CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims benefit to U.S. Provisional Application No. 63/078,234, filed Sep. 14, 2020, entitled “USER INTERFACES FOR INDICATING DISTANCE,” the entire contents of which are hereby incorporated by reference. 
    
    
     FIELD 
     The present disclosure relates generally to computer user interfaces, and more specifically to techniques for providing an indication of distance to an entity. 
     BACKGROUND 
     Computer systems can include features for identifying entities using, for example, a camera of the computer systems. Computer systems can also determine a distance between two stationary points within a field of view of the camera. 
     BRIEF SUMMARY 
     Some techniques for providing a distance using electronic devices, however, are generally cumbersome and inefficient. For example, some existing techniques provide distance between two or more points within a field of view of an electronic device, but do not provide an indication of distance between a point within the field of view and the electronic device itself. In addition, some existing techniques use a complex and time-consuming user interface, which may include multiple key presses or keystrokes. Existing techniques require more time than necessary, wasting user time and device energy. This latter consideration is particularly important in battery-operated devices. 
     Accordingly, the present technique provides electronic devices with faster, more efficient methods and interfaces for providing an indication of distance to an entity. Such methods and interfaces optionally complement or replace other methods for providing an indication of distance to an entity. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated computing devices, such methods and interfaces conserve power and increase the time between battery charges. 
     In accordance with some embodiments, a method performed at a computer system that is in communication with one or more cameras and a display generation component is described. The method comprises: displaying, via the display generation component, a visual representation of a field of view of the one or more cameras; in accordance with a determination that an entity meets a set of detection criteria, the set of detection criteria including a first criterion that is met when the entity is detected within the field of view of the one or more cameras, providing, concurrently with the visual representation of the field of view that includes the entity, one or more indicators of distance between the computer system and the entity, wherein providing the one or more indicators of distance includes: displaying, via the display generation component, a visual distance indicator that indicates the distance between the computer system and the entity; and in accordance with a failure to determine that an entity meets the set of detection criteria, forgoing providing the one or more indicators of a distance between the computer system and the entity. 
     In accordance with some embodiments, a non-transitory computer-readable storage medium is described. The non-transitory computer-readable storage medium stores one or more programs configured to be executed by one or more processors of a computer system that is in communication with one or more cameras and a display generation component, the one or more programs including instructions for: displaying, via the display generation component, a visual representation of a field of view of the one or more cameras; in accordance with a determination that an entity meets a set of detection criteria, the set of detection criteria including a first criterion that is met when the entity is detected within the field of view of the one or more cameras, providing, concurrently with the visual representation of the field of view that includes the entity, one or more indicators of distance between the computer system and the entity, wherein providing the one or more indicators of distance includes: displaying, via the display generation component, a visual distance indicator that indicates the distance between the computer system and the entity; and in accordance with a failure to determine that an entity meets the set of detection criteria, forgoing providing the one or more indicators of a distance between the computer system and the entity. 
     In accordance with some embodiments, a transitory computer-readable storage medium is described. The transitory computer-readable storage medium stores one or more programs configured to be executed by one or more processors of a computer system that is in communication with one or more cameras and a display generation component, the one or more programs including instructions for: displaying, via the display generation component, a visual representation of a field of view of the one or more cameras; in accordance with a determination that an entity meets a set of detection criteria, the set of detection criteria including a first criterion that is met when the entity is detected within the field of view of the one or more cameras, providing, concurrently with the visual representation of the field of view that includes the entity, one or more indicators of distance between the computer system and the entity, wherein providing the one or more indicators of distance includes: displaying, via the display generation component, a visual distance indicator that indicates the distance between the computer system and the entity; and in accordance with a failure to determine that an entity meets the set of detection criteria, forgoing providing the one or more indicators of a distance between the computer system and the entity. 
     In accordance with some embodiments, a computer system is described. The computer system comprises: one or more cameras; a display generation component; one or more processors; and memory storing one or more programs configured to be executed by the one or more processors, the one or more programs including instructions for: displaying, via the display generation component, a visual representation of a field of view of the one or more cameras; in accordance with a determination that an entity meets a set of detection criteria, the set of detection criteria including a first criterion that is met when the entity is detected within the field of view of the one or more cameras, providing, concurrently with the visual representation of the field of view that includes the entity, one or more indicators of distance between the computer system and the entity, wherein providing the one or more indicators of distance includes: displaying, via the display generation component, a visual distance indicator that indicates the distance between the computer system and the entity; and in accordance with a failure to determine that an entity meets the set of detection criteria, forgoing providing the one or more indicators of a distance between the computer system and the entity.

     DESCRIPTION OF EMBODIMENTS 
     The following description sets forth exemplary methods, parameters, and the like. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure but is instead provided as a description of exemplary embodiments. 
     There is a need for electronic devices that provide efficient methods and interfaces for providing an indication of distance to an entity. For example, a user that is vision impaired can have difficulty estimating a distance between the user and another person or object in front of the user. Displaying a user interface on an electronic device that provides an indication of distance to an entity enable the user to quickly and accurately determine how far another person or object is to the electronic device, and thus, how far another person or object is to the user holding the electronic device. Such techniques can reduce the cognitive burden on a user who request a determination of distance to an entity, thereby enhancing productivity. Further, such techniques can reduce processor and battery power otherwise wasted on redundant user inputs. 
     Below,  FIGS.  1 A- 1 B,  2 ,  3 ,  4 A- 4 B, and  5 A- 5 B  provide a description of exemplary devices for performing the techniques for providing an indication of distance to an entity.  FIGS.  6 A- 6 M  illustrate exemplary user interfaces for providing an indication of distance to an entity.  FIG.  7    is a flow diagram illustrating methods of providing an indication of distance to an entity in accordance with some embodiments. The user interfaces in  FIGS.  6 A- 6 M  are used to illustrate the processes described below, including the processes in  FIG.  7   . 
     Although the following description uses terms “first,” “second,” etc. to describe various elements, these elements should not be limited by the terms. These terms are only used to distinguish one element from another. For example, a first touch could be termed a second touch, and, similarly, a second touch could be termed a first touch, without departing from the scope of the various described embodiments. The first touch and the second touch are both touches, but they are not the same touch. 
     The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     The term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context. 
     Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touchpad). In some embodiments, the electronic device is a computer system that is in communication (e.g., via wireless communication, via wired communication) with a display generation component. The display generation component is configured to provide visual output, such as display via a CRT display, display via an LED display, or display via image projection. In some embodiments, the display generation component is integrated with the computer system. In some embodiments, the display generation component is separate from the computer system. As used herein, “displaying” content includes causing to display the content (e.g., video data rendered or decoded by display controller  156 ) by transmitting, via a wired or wireless connection, data (e.g., image data or video data) to an integrated or external display generation component to visually produce the content. 
     In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse, and/or a joystick. 
     The device typically supports a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application. 
     The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user. 
     Attention is now directed toward embodiments of portable devices with touch-sensitive displays.  FIG.  1 A  is a block diagram illustrating portable multifunction device  100  with touch-sensitive display system  112  in accordance with some embodiments. Touch-sensitive display  112  is sometimes called a “touch screen” for convenience and is sometimes known as or called a “touch-sensitive display system.” Device  100  includes memory  102  (which optionally includes one or more computer-readable storage mediums), memory controller  122 , one or more processing units (CPUs)  120 , peripherals interface  118 , RF circuitry  108 , audio circuitry  110 , speaker  111 , microphone  113 , input/output (I/O) subsystem  106 , other input control devices  116 , and external port  124 . Device  100  optionally includes one or more optical sensors  164 . Device  100  optionally includes one or more contact intensity sensors  165  for detecting intensity of contacts on device  100  (e.g., a touch-sensitive surface such as touch-sensitive display system  112  of device  100 ). Device  100  optionally includes one or more tactile output generators  167  for generating tactile outputs on device  100  (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system  112  of device  100  or touchpad  355  of device  300 ). These components optionally communicate over one or more communication buses or signal lines  103 . 
     As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure, and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button). 
     As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user&#39;s sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user&#39;s hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user&#39;s movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user. 
     It should be appreciated that device  100  is only one example of a portable multifunction device, and that device  100  optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in  FIG.  1 A  are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application-specific integrated circuits. 
     Memory  102  optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Memory controller  122  optionally controls access to memory  102  by other components of device  100 . 
     Peripherals interface  118  can be used to couple input and output peripherals of the device to CPU  120  and memory  102 . The one or more processors  120  run or execute various software programs and/or sets of instructions stored in memory  102  to perform various functions for device  100  and to process data. In some embodiments, peripherals interface  118 , CPU  120 , and memory controller  122  are, optionally, implemented on a single chip, such as chip  104 . In some other embodiments, they are, optionally, implemented on separate chips. 
     RF (radio frequency) circuitry  108  receives and sends RF signals, also called electromagnetic signals. RF circuitry  108  converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. RF circuitry  108  optionally includes well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. RF circuitry  108  optionally communicates with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication. The RF circuitry  108  optionally includes well-known circuitry for detecting near field communication (NFC) fields, such as by a short-range communication radio. The wireless communication optionally uses any of a plurality of communications standards, protocols, and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA), Evolution, Data-Only (EV-DO), HSPA, HSPA+, Dual-Cell HSPA (DC-HSPDA), long term evolution (LTE), near field communication (NFC), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Bluetooth Low Energy (BTLE), Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, and/or IEEE 802.11ac), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e-mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document. 
     Audio circuitry  110 , speaker  111 , and microphone  113  provide an audio interface between a user and device  100 . Audio circuitry  110  receives audio data from peripherals interface  118 , converts the audio data to an electrical signal, and transmits the electrical signal to speaker  111 . Speaker  111  converts the electrical signal to human-audible sound waves. Audio circuitry  110  also receives electrical signals converted by microphone  113  from sound waves. Audio circuitry  110  converts the electrical signal to audio data and transmits the audio data to peripherals interface  118  for processing. Audio data is, optionally, retrieved from and/or transmitted to memory  102  and/or RF circuitry  108  by peripherals interface  118 . In some embodiments, audio circuitry  110  also includes a headset jack (e.g.,  212 ,  FIG.  2   ). The headset jack provides an interface between audio circuitry  110  and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone). 
     I/O subsystem  106  couples input/output peripherals on device  100 , such as touch screen  112  and other input control devices  116 , to peripherals interface  118 . I/O subsystem  106  optionally includes display controller  156 , optical sensor controller  158 , depth camera controller  169 , intensity sensor controller  159 , haptic feedback controller  161 , and one or more input controllers  160  for other input or control devices. The one or more input controllers  160  receive/send electrical signals from/to other input control devices  116 . The other input control devices  116  optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some embodiments, input controller(s)  160  are, optionally, coupled to any (or none) of the following: a keyboard, an infrared port, a USB port, and a pointer device such as a mouse. The one or more buttons (e.g.,  208 ,  FIG.  2   ) optionally include an up/down button for volume control of speaker  111  and/or microphone  113 . The one or more buttons optionally include a push button (e.g.,  206 ,  FIG.  2   ). In some embodiments, the electronic device is a computer system that is in communication (e.g., via wireless communication, via wired communication) with one or more input devices. In some embodiments, the one or more input devices include a touch-sensitive surface (e.g., a trackpad, as part of a touch-sensitive display). In some embodiments, the one or more input devices include one or more camera sensors (e.g., one or more optical sensors  164  and/or one or more depth camera sensors  175 ), such as for tracking a user&#39;s gestures (e.g., hand gestures) as input. In some embodiments, the one or more input devices are integrated with the computer system. In some embodiments, the one or more input devices are separate from the computer system. 
     A quick press of the push button optionally disengages a lock of touch screen  112  or optionally begins a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, U.S. Pat. No. 7,657,849, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g.,  206 ) optionally turns power to device  100  on or off. The functionality of one or more of the buttons are, optionally, user-customizable. Touch screen  112  is used to implement virtual or soft buttons and one or more soft keyboards. 
     Touch-sensitive display  112  provides an input interface and an output interface between the device and a user. Display controller  156  receives and/or sends electrical signals from/to touch screen  112 . Touch screen  112  displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output optionally corresponds to user-interface objects. 
     Touch screen  112  has a touch-sensitive surface, sensor, or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen  112  and display controller  156  (along with any associated modules and/or sets of instructions in memory  102 ) detect contact (and any movement or breaking of the contact) on touch screen  112  and convert the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages, or images) that are displayed on touch screen  112 . In an exemplary embodiment, a point of contact between touch screen  112  and the user corresponds to a finger of the user. 
     Touch screen  112  optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch screen  112  and display controller  156  optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen  112 . In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone® and iPod Touch® from Apple Inc. of Cupertino, Calif. 
     A touch-sensitive display in some embodiments of touch screen  112  is, optionally, analogous to the multi-touch sensitive touchpads described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, touch screen  112  displays visual output from device  100 , whereas touch-sensitive touchpads do not provide visual output. 
     A touch-sensitive display in some embodiments of touch screen  112  is described in the following applications: (1) U.S. patent application Ser.

     Touch screen  112  optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user optionally makes contact with touch screen  112  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     In some embodiments, in addition to the touch screen, device  100  optionally includes a touchpad for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch screen  112  or an extension of the touch-sensitive surface formed by the touch screen. 
     Device  100  also includes power system  162  for powering the various components. Power system  162  optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices. 
     Device  100  optionally also includes one or more optical sensors  164 .  FIG.  1 A  shows an optical sensor coupled to optical sensor controller  158  in I/O subsystem  106 . Optical sensor  164  optionally includes charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor  164  receives light from the environment, projected through one or more lenses, and converts the light to data representing an image. In conjunction with imaging module  143  (also called a camera module), optical sensor  164  optionally captures still images or video. In some embodiments, an optical sensor is located on the back of device  100 , opposite touch screen display  112  on the front of the device so that the touch screen display is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user&#39;s image is, optionally, obtained for video conferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of optical sensor  164  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor  164  is used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     Device  100  optionally also includes one or more depth camera sensors  175 .  FIG.  1 A  shows a depth camera sensor coupled to depth camera controller  169  in I/O subsystem  106 . Depth camera sensor  175  receives data from the environment to create a three dimensional model of an object (e.g., a face) within a scene from a viewpoint (e.g., a depth camera sensor). In some embodiments, in conjunction with imaging module  143  (also called a camera module), depth camera sensor  175  is optionally used to determine a depth map of different portions of an image captured by the imaging module  143 . In some embodiments, a depth camera sensor is located on the front of device  100  so that the user&#39;s image with depth information is, optionally, obtained for video conferencing while the user views the other video conference participants on the touch screen display and to capture selfies with depth map data. In some embodiments, the depth camera sensor  175  is located on the back of device, or on the back and the front of the device  100 . In some embodiments, the position of depth camera sensor  175  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a depth camera sensor  175  is used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     In some embodiments, a depth map (e.g., depth map image) contains information (e.g., values) that relates to the distance of objects in a scene from a viewpoint (e.g., a camera, an optical sensor, a depth camera sensor). In one embodiment of a depth map, each depth pixel defines the position in the viewpoint&#39;s Z-axis where its corresponding two-dimensional pixel is located. In some embodiments, a depth map is composed of pixels wherein each pixel is defined by a value (e.g., 0-255). For example, the “0” value represents pixels that are located at the most distant place in a “three dimensional” scene and the “255” value represents pixels that are located closest to a viewpoint (e.g., a camera, an optical sensor, a depth camera sensor) in the “three dimensional” scene. In other embodiments, a depth map represents the distance between an object in a scene and the plane of the viewpoint. In some embodiments, the depth map includes information about the relative depth of various features of an object of interest in view of the depth camera (e.g., the relative depth of eyes, nose, mouth, ears of a user&#39;s face). In some embodiments, the depth map includes information that enables the device to determine contours of the object of interest in a z direction. 
     Device  100  optionally also includes one or more contact intensity sensors  165 .  FIG.  1 A  shows a contact intensity sensor coupled to intensity sensor controller  159  in I/O subsystem  106 . Contact intensity sensor  165  optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor  165  receives contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ). In some embodiments, at least one contact intensity sensor is located on the back of device  100 , opposite touch screen display  112 , which is located on the front of device  100 . 
     Device  100  optionally also includes one or more proximity sensors  166 .  FIG.  1 A  shows proximity sensor  166  coupled to peripherals interface  118 . Alternately, proximity sensor  166  is, optionally, coupled to input controller  160  in I/O subsystem  106 . Proximity sensor  166  optionally performs as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety.

     Device  100  optionally also includes one or more tactile output generators  167 .  FIG.  1 A  shows a tactile output generator coupled to haptic feedback controller  161  in I/O subsystem  106 . Tactile output generator  167  optionally includes one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Contact intensity sensor  165  receives tactile feedback generation instructions from haptic feedback module  133  and generates tactile outputs on device  100  that are capable of being sensed by a user of device  100 . In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device  100 ) or laterally (e.g., back and forth in the same plane as a surface of device  100 ). In some embodiments, at least one tactile output generator sensor is located on the back of device  100 , opposite touch screen display  112 , which is located on the front of device  100 .

In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device  100  optionally includes, in addition to accelerometer(s)  168 , a magnetometer and a GPS (or GLONASS or other global navigation system) receiver for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device  100 . 
     In some embodiments, the software components stored in memory  102  include operating system  126 , communication module (or set of instructions)  128 , contact/motion module (or set of instructions)  130 , graphics module (or set of instructions)  132 , text input module (or set of instructions)  134 , Global Positioning System (GPS) module (or set of instructions)  135 , and applications (or sets of instructions)  136 . Furthermore, in some embodiments, memory  102  ( FIG.  1 A ) or  370  ( FIG.  3   ) stores device/global internal state  157 , as shown in  FIGS.  1 A and  3   . Device/global internal state  157  includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display  112 ; sensor state, including information obtained from the device&#39;s various sensors and input control devices  116 ; and location information concerning the device&#39;s location and/or attitude. 
     Operating system  126  (e.g., Darwin, RTXC, LINUX, UNIX, OS X, iOS, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     Communication module  128  facilitates communication with other devices over one or more external ports  124  and also includes various software components for handling data received by RF circuitry  108  and/or external port  124 . External port  124  (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with, the 30-pin connector used on iPod® (trademark of Apple Inc.) devices. 
     Contact/motion module  130  optionally detects contact with touch screen  112  (in conjunction with display controller  156 ) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module  130  includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module  130  receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module  130  and display controller  156  detect contact on a touchpad. 
     In some embodiments, contact/motion module  130  uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device  100 ). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined threshold values without changing the trackpad or touch screen display hardware. Additionally, in some implementations, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter). 
     Contact/motion module  130  optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (liftoff) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (liftoff) event. 
     Graphics module  132  includes various known software components for rendering and displaying graphics on touch screen  112  or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including, without limitation, text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations, and the like. 
     In some embodiments, graphics module  132  stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module  132  receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller  156 . 
     Haptic feedback module  133  includes various software components for generating instructions used by tactile output generator(s)  167  to produce tactile outputs at one or more locations on device  100  in response to user interactions with device  100 . 
     Text input module  134 , which is, optionally, a component of graphics module  132 , provides soft keyboards for entering text in various applications (e.g., contacts  137 , e-mail  140 , IM  141 , browser  147 , and any other application that needs text input). 
     GPS module  135  determines the location of the device and provides this information for use in various applications (e.g., to telephone  138  for use in location-based dialing; to camera  143  as picture/video metadata; and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

These modules (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. For example, video player module is, optionally, combined with music player module into a single module (e.g., video and music player module  152 ,  FIG.  1 A ). In some embodiments, memory  102  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  102  optionally stores additional modules and data structures not described above. 
     In some embodiments, device  100  is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device  100 , the number of physical input control devices (such as push buttons, dials, and the like) on device  100  is, optionally, reduced. 
     The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device  100  to a main, home, or root menu from any user interface that is displayed on device  100 . In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad. 
       FIG.  1 B  is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory  102  ( FIG.  1 A ) or  370  ( FIG.  3   ) includes event sorter  170  (e.g., in operating system  126 ) and a respective application  136 - 1  (e.g., any of the aforementioned applications  137 - 151 ,  155 ,  380 - 390 ). 
     Event sorter  170  receives event information and determines the application  136 - 1  and application view  191  of application  136 - 1  to which to deliver the event information. Event sorter  170  includes event monitor  171  and event dispatcher module  174 . In some embodiments, application  136 - 1  includes application internal state  192 , which indicates the current application view(s) displayed on touch-sensitive display  112  when the application is active or executing. In some embodiments, device/global internal state  157  is used by event sorter  170  to determine which application(s) is (are) currently active, and application internal state  192  is used by event sorter  170  to determine application views  191  to which to deliver event information. 
     In some embodiments, application internal state  192  includes additional information, such as one or more of: resume information to be used when application  136 - 1  resumes execution, user interface state information that indicates information being displayed or that is ready for display by application  136 - 1 , a state queue for enabling the user to go back to a prior state or view of application  136 - 1 , and a redo/undo queue of previous actions taken by the user. 
     Event monitor  171  receives event information from peripherals interface  118 . Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display  112 , as part of a multi-touch gesture). Peripherals interface  118  transmits information it receives from I/O subsystem  106  or a sensor, such as proximity sensor  166 , accelerometer(s)  168 , and/or microphone  113  (through audio circuitry  110 ). Information that peripherals interface  118  receives from I/O subsystem  106  includes information from touch-sensitive display  112  or a touch-sensitive surface. 
     In some embodiments, event monitor  171  sends requests to the peripherals interface  118  at predetermined intervals. In response, peripherals interface  118  transmits event information. In other embodiments, peripherals interface  118  transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration). 
     In some embodiments, event sorter  170  also includes a hit view determination module  172  and/or an active event recognizer determination module  173 . 
     Hit view determination module  172  provides software procedures for determining where a sub-event has taken place within one or more views when touch-sensitive display  112  displays more than one view. Views are made up of controls and other elements that a user can see on the display. 
     Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture. 
     Hit view determination module  172  receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module  172  identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (e.g., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module  172 , the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view. 
     Active event recognizer determination module  173  determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module  173  determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module  173  determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views. 
     Event dispatcher module  174  dispatches the event information to an event recognizer (e.g., event recognizer  180 ). In embodiments including active event recognizer determination module  173 , event dispatcher module  174  delivers the event information to an event recognizer determined by active event recognizer determination module  173 . In some embodiments, event dispatcher module  174  stores in an event queue the event information, which is retrieved by a respective event receiver  182 . 
     In some embodiments, operating system  126  includes event sorter  170 . Alternatively, application  136 - 1  includes event sorter  170 . In yet other embodiments, event sorter  170  is a stand-alone module, or a part of another module stored in memory  102 , such as contact/motion module  130 . 
     In some embodiments, application  136 - 1  includes a plurality of event handlers  190  and one or more application views  191 , each of which includes instructions for handling touch events that occur within a respective view of the application&#39;s user interface. Each application view  191  of the application  136 - 1  includes one or more event recognizers  180 . Typically, a respective application view  191  includes a plurality of event recognizers  180 . In other embodiments, one or more of event recognizers  180  are part of a separate module, such as a user interface kit or a higher level object from which application  136 - 1  inherits methods and other properties. In some embodiments, a respective event handler  190  includes one or more of: data updater  176 , object updater  177 , GUI updater  178 , and/or event data  179  received from event sorter  170 . Event handler  190  optionally utilizes or calls data updater  176 , object updater  177 , or GUI updater  178  to update the application internal state  192 . Alternatively, one or more of the application views  191  include one or more respective event handlers  190 . Also, in some embodiments, one or more of data updater  176 , object updater  177 , and GUI updater  178  are included in a respective application view  191 . 
     A respective event recognizer  180  receives event information (e.g., event data  179 ) from event sorter  170  and identifies an event from the event information. Event recognizer  180  includes event receiver  182  and event comparator  184 . In some embodiments, event recognizer  180  also includes at least a subset of: metadata  183 , and event delivery instructions  188  (which optionally include sub-event delivery instructions). 
     Event receiver  182  receives event information from event sorter  170 . The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device. 
     Event comparator  184  compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator  184  includes event definitions  186 . Event definitions  186  contain definitions of events (e.g., predefined sequences of sub-events), for example, event  1  ( 187 - 1 ), event  2  ( 187 - 2 ), and others. In some embodiments, sub-events in an event ( 187 ) include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event  1  ( 187 - 1 ) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first liftoff (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second liftoff (touch end) for a predetermined phase. In another example, the definition for event  2  ( 187 - 2 ) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display  112 , and liftoff of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers  190 . 
     In some embodiments, event definition  187  includes a definition of an event for a respective user-interface object. In some embodiments, event comparator  184  performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display  112 , when a touch is detected on touch-sensitive display  112 , event comparator  184  performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler  190 , the event comparator uses the result of the hit test to determine which event handler  190  should be activated. For example, event comparator  184  selects an event handler associated with the sub-event and the object triggering the hit test. 
     In some embodiments, the definition for a respective event ( 187 ) also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer&#39;s event type. 
     When a respective event recognizer  180  determines that the series of sub-events do not match any of the events in event definitions  186 , the respective event recognizer  180  enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture. 
     In some embodiments, a respective event recognizer  180  includes metadata  183  with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy. 
     In some embodiments, a respective event recognizer  180  activates event handler  190  associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer  180  delivers event information associated with the event to event handler  190 . Activating an event handler  190  is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer  180  throws a flag associated with the recognized event, and event handler  190  associated with the flag catches the flag and performs a predefined process. 
     In some embodiments, event delivery instructions  188  include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process. 
     In some embodiments, data updater  176  creates and updates data used in application  136 - 1 . For example, data updater  176  updates the telephone number used in contacts module  137 , or stores a video file used in video player module. In some embodiments, object updater  177  creates and updates objects used in application  136 - 1 . For example, object updater  177  creates a new user-interface object or updates the position of a user-interface object. GUI updater  178  updates the GUI. For example, GUI updater  178  prepares display information and sends it to graphics module  132  for display on a touch-sensitive display. 
     In some embodiments, event handler(s)  190  includes or has access to data updater  176 , object updater  177 , and GUI updater  178 . In some embodiments, data updater  176 , object updater  177 , and GUI updater  178  are included in a single module of a respective application  136 - 1  or application view  191 . In other embodiments, they are included in two or more software modules. 
     It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices  100  with input devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc. on touchpads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized. 
       FIG.  2    illustrates a portable multifunction device  100  having a touch screen  112  in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI)  200 . In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers  202  (not drawn to scale in the figure) or one or more styluses  203  (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward), and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device  100 . In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap. 
     Device  100  optionally also include one or more physical buttons, such as “home” or menu button  204 . As described previously, menu button  204  is, optionally, used to navigate to any application  136  in a set of applications that are, optionally, executed on device  100 . Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen  112 . 
     In some embodiments, device  100  includes touch screen  112 , menu button  204 , push button  206  for powering the device on/off and locking the device, volume adjustment button(s)  208 , subscriber identity module (SIM) card slot  210 , headset jack  212 , and docking/charging external port  124 . Push button  206  is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device  100  also accepts verbal input for activation or deactivation of some functions through microphone  113 . Device  100  also, optionally, includes one or more contact intensity sensors  165  for detecting intensity of contacts on touch screen  112  and/or one or more tactile output generators  167  for generating tactile outputs for a user of device  100 . 
       FIG.  3    is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device  300  need not be portable. In some embodiments, device  300  is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child&#39;s learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device  300  typically includes one or more processing units (CPUs)  310 , one or more network or other communications interfaces  360 , memory  370 , and one or more communication buses  320  for interconnecting these components. Communication buses  320  optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device  300  includes input/output (I/O) interface  330  comprising display  340 , which is typically a touch screen display. I/O interface  330  also optionally includes a keyboard and/or mouse (or other pointing device)  350  and touchpad  355 , tactile output generator  357  for generating tactile outputs on device  300  (e.g., similar to tactile output generator(s)  167  described above with reference to  FIG.  1 A ), sensors  359  (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s)  165  described above with reference to  FIG.  1 A ). Memory  370  includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory  370  optionally includes one or more storage devices remotely located from CPU(s)  310 . In some embodiments, memory  370  stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory  102  of portable multifunction device  100  ( FIG.  1 A ), or a subset thereof. Furthermore, memory  370  optionally stores additional programs, modules, and data structures not present in memory  102  of portable multifunction device  100 . For example, memory  370  of device  300  optionally stores drawing module  380 , presentation module  382 , word processing module  384 , website creation module  386 , disk authoring module  388 , and/or spreadsheet module  390 , while memory  102  of portable multifunction device  100  ( FIG.  1 A ) optionally does not store these modules. 
     Each of the above-identified elements in  FIG.  3    is, optionally, stored in one or more of the previously mentioned memory devices. Each of the above-identified modules corresponds to a set of instructions for performing a function described above. The above-identified modules or programs (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. In some embodiments, memory  370  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  370  optionally stores additional modules and data structures not described above. 
     Attention is now directed towards embodiments of user interfaces that are, optionally, implemented on, for example, portable multifunction device  100 . 
       FIG.  4 A  illustrates an exemplary user interface for a menu of applications on portable multifunction device  100  in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device  300 . In some embodiments, user interface  400  includes the following elements, or a subset or superset thereof:
         Signal strength indicator(s)  402  for wireless communication(s), such as cellular and Wi-Fi signals;   Time  404 ;   Bluetooth indicator  405 ;   Battery status indicator  406 ;   Tray  408  with icons for frequently used applications, such as:
           Icon  416  for telephone module  138 , labeled “Phone,” which optionally includes an indicator  414  of the number of missed calls or voicemail messages;   Icon  418  for e-mail client module  140 , labeled “Mail,” which optionally includes an indicator  410  of the number of unread e-mails;   Icon  420  for browser module  147 , labeled “Browser;” and   Icon  422  for video and music player module  152 , also referred to as iPod (trademark of Apple Inc.) module  152 , labeled “iPod;” and   
           Icons for other applications, such as:
           Icon  424  for IM module  141 , labeled “Messages;”   Icon  426  for calendar module  148 , labeled “Calendar;”   Icon  428  for image management module  144 , labeled “Photos;”   Icon  430  for camera module  143 , labeled “Camera;”   Icon  432  for online video module  155 , labeled “Online Video;”   Icon  434  for stocks widget  149 - 2 , labeled “Stocks;”   Icon  436  for map module  154 , labeled “Maps;”   Icon  438  for weather widget  149 - 1 , labeled “Weather;”   Icon  440  for alarm clock widget  149 - 4 , labeled “Clock;”   Icon  442  for workout support module  142 , labeled “Workout Support;”   Icon  444  for notes module  153 , labeled “Notes;” and   Icon  446  for a settings application or module, labeled “Settings,” which provides access to settings for device  100  and its various applications  136 .   
               

     It should be noted that the icon labels illustrated in  FIG.  4 A  are merely exemplary. For example, icon  422  for video and music player module  152  is labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon. 
       FIG.  4 B  illustrates an exemplary user interface on a device (e.g., device  300 ,  FIG.  3   ) with a touch-sensitive surface  451  (e.g., a tablet or touchpad  355 ,  FIG.  3   ) that is separate from the display  450  (e.g., touch screen display  112 ). Device  300  also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors  359 ) for detecting intensity of contacts on touch-sensitive surface  451  and/or one or more tactile output generators  357  for generating tactile outputs for a user of device  300 . 
     Although some of the examples that follow will be given with reference to inputs on touch screen display  112  (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in  FIG.  4 B . In some embodiments, the touch-sensitive surface (e.g.,  451  in  FIG.  4 B ) has a primary axis (e.g.,  452  in  FIG.  4 B ) that corresponds to a primary axis (e.g.,  453  in  FIG.  4 B ) on the display (e.g.,  450 ). In accordance with these embodiments, the device detects contacts (e.g.,  460  and  462  in  FIG.  4 B ) with the touch-sensitive surface  451  at locations that correspond to respective locations on the display (e.g., in  FIG.  4 B,  460    corresponds to  468  and  462  corresponds to  470 ). In this way, user inputs (e.g., contacts  460  and  462 , and movements thereof) detected by the device on the touch-sensitive surface (e.g.,  451  in  FIG.  4 B ) are used by the device to manipulate the user interface on the display (e.g.,  450  in  FIG.  4 B ) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein. 
     Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse-based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously. 
       FIG.  5 A  illustrates exemplary personal electronic device  500 . Device  500  includes body  502 . In some embodiments, device  500  can include some or all of the features described with respect to devices  100  and  300  (e.g.,  FIGS.  1 A- 4 B ). In some embodiments, device  500  has touch-sensitive display screen  504 , hereafter touch screen  504 . Alternatively, or in addition to touch screen  504 , device  500  has a display and a touch-sensitive surface. As with devices  100  and  300 , in some embodiments, touch screen  504  (or the touch-sensitive surface) optionally includes one or more intensity sensors for detecting intensity of contacts (e.g., touches) being applied. The one or more intensity sensors of touch screen  504  (or the touch-sensitive surface) can provide output data that represents the intensity of touches. The user interface of device  500  can respond to touches based on their intensity, meaning that touches of different intensities can invoke different user interface operations on device  500 .

       FIG.  5 B  depicts exemplary personal electronic device  500 . In some embodiments, device  500  can include some or all of the components described with respect to  FIGS.  1 A,  1 B , and  3 . Device  500  has bus  512  that operatively couples I/O section  514  with one or more computer processors  516  and memory  518 . I/O section  514  can be connected to display  504 , which can have touch-sensitive component  522  and, optionally, intensity sensor  524  (e.g., contact intensity sensor). In addition, I/O section  514  can be connected with communication unit  530  for receiving application and operating system data, using Wi-Fi, Bluetooth, near field communication (NFC), cellular, and/or other wireless communication techniques. Device  500  can include input mechanisms  506  and/or  508 . Input mechanism  506  is, optionally, a rotatable input device or a depressible and rotatable input device, for example. Input mechanism  508  is, optionally, a button, in some examples. 
     Input mechanism  508  is, optionally, a microphone, in some examples. Personal electronic device  500  optionally includes various sensors, such as GPS sensor  532 , accelerometer  534 , directional sensor  540  (e.g., compass), gyroscope  536 , motion sensor  538 , and/or a combination thereof, all of which can be operatively connected to I/O section  514 . 
     Memory  518  of personal electronic device  500  can include one or more non-transitory computer-readable storage mediums, for storing computer-executable instructions, which, when executed by one or more computer processors  516 , for example, can cause the computer processors to perform the techniques described below, including process  700  ( FIG.  7   ). A computer-readable storage medium can be any medium that can tangibly contain or store computer-executable instructions for use by or in connection with the instruction execution system, apparatus, or device. In some examples, the storage medium is a transitory computer-readable storage medium. In some examples, the storage medium is a non-transitory computer-readable storage medium. The non-transitory computer-readable storage medium can include, but is not limited to, magnetic, optical, and/or semiconductor storages. Examples of such storage include magnetic disks, optical discs based on CD, DVD, or Blu-ray technologies, as well as persistent solid-state memory such as flash, solid-state drives, and the like. Personal electronic device  500  is not limited to the components and configuration of  FIG.  5 B , but can include other or additional components in multiple configurations. 
     As used here, the term “affordance” refers to a user-interactive graphical user interface object that is, optionally, displayed on the display screen of devices  100 ,  300 , and/or  500  ( FIGS.  1 A,  3 , and  5 A- 5 B ). For example, an image (e.g., icon), a button, and text (e.g., hyperlink) each optionally constitute an affordance. 
     As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad  355  in  FIG.  3    or touch-sensitive surface  451  in  FIG.  4 B ) while the cursor is over a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch screen display (e.g., touch-sensitive display system  112  in  FIG.  1 A  or touch screen  112  in  FIG.  4 A ) that enables direct interaction with user interface elements on the touch screen display, a detected contact on the touch screen acts as a “focus selector” so that when an input (e.g., a press input by the contact) is detected on the touch screen display at a location of a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch screen display) that is controlled by the user so as to communicate the user&#39;s intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device). 
     Tactile output patterns may have a corresponding characteristic frequency that affects the “pitch” of a haptic sensation that is felt by a user from a tactile output with that characteristic frequency. For a continuous tactile output, the characteristic frequency represents the number of cycles that are completed within a given period of time (e.g., cycles per second) by the moveable mass of the tactile output generator. For a discrete tactile output, a discrete output signal (e.g., with 0.5, 1, or 2 cycles) is generated, and the characteristic frequency value specifies how fast the moveable mass needs to move to generate a tactile output with that characteristic frequency. 
     Tactile output patterns may have a characteristic amplitude that affects the amount of energy that is contained in a tactile signal, or a “strength” of a haptic sensation that may be felt by a user through a tactile output with that characteristic amplitude. In some embodiments, the characteristic amplitude of a tactile output pattern refers to an absolute or normalized value that represents the maximum displacement of the moveable mass from a neutral position when generating the tactile output. In some embodiments, the characteristic amplitude of a tactile output pattern is adjustable, e.g., by a fixed or dynamically determined gain factor (e.g., a value between 0 and 1), in accordance with various conditions (e.g., customized based on user interface contexts and behaviors) and/or preconfigured metrics (e.g., input-based metrics, and/or user-interface-based metrics). In some embodiments, the characteristic amplitude of a tactile output pattern may be modulated by an “envelope” and the peaks of adjacent cycles may have different amplitudes, where one of the waveforms shown above is further modified by multiplication by an envelope parameter that changes over time (e.g., from 0 to 1) to gradually adjust amplitude of portions of the tactile output over time as the tactile output is being generated. 
     For ease of explanation, the descriptions of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting either: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, and/or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold. 
     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that are implemented on an electronic device, such as portable multifunction device  100 , device  300 , or device  500 . 
       FIGS.  6 A- 6 M  illustrate exemplary user interfaces for providing an indication of distance to an entity, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIG.  7   . 
       FIG.  6 A  illustrates electronic device  600  having a display  602  and side button  604 . At  FIG.  6 A , electronic device  600  displays user interface  606  on display  602 , where user interface  606  corresponds to a camera application that enables a user to capture images using a camera (e.g., of one or more cameras) of electronic device  600 . For instance, user interface  606  includes a field of view representation  606   a  that includes a visual representation of an area surrounding electronic device  600  and that is within a field of view of the camera. User interface  606  also includes a capture user interface object  606   b . In response to detecting user input corresponding to capture user interface object  606   b , electronic device  600  causes an image to be captured that is within the field of view of the camera. Additionally, user interface  606  includes image library user interface object  606   c . In response to detecting user input corresponding to selection of image library user interface object  606   c , electronic device  600  displays an image library (e.g., an image library user interface) that includes images captured by electronic device  600 . 
     At  FIG.  6 A , electronic device  600  detects user input  650   a  (e.g., a multi-tap or multi-press gesture, such as three successive taps or presses) on side button  604 . In response to detecting user input  650   a , electronic device  600  displays user interface  608  corresponding to a magnification application, as shown at  FIG.  6 B . For example, the magnification application enables a user to use device  600  to magnify (e.g., zoom) a representation of an area surrounding electronic device  600  that is within the field of view of the camera. In some embodiments, in response to detecting user input  650   a  while displaying user interface  606 , electronic device displays user interface  608 . In some embodiments, in response to detecting user input  650   a , electronic device  600  displays user interface  608  independent of the user interface being displayed (e.g., a user interface other than  606 ). 
     At  FIG.  6 B , user interface  608  includes field of view representation  608   a  that includes a visual representation of an area surrounding electronic device  600  and that is within the field of view of the camera. User interface  608  also includes magnifier user interface object  608   b , flash user interface object  608   c , brightness user interface object  608   d , contrast user interface object  608   e , color user interface object  608   f , distancing user interface object  608   g , settings user interface object  608   h , and capture user interface object  608   i . In response to detecting user input (e.g., a swipe gesture and/or a tap gesture) on magnifier user interface object  608   b , electronic device  600  is configured to zoom in or out the visual representation displayed at field of view representation  608   a . In other words, in response to detecting a right swipe gesture on the magnifier user interface object  608   b , electronic device  600  zooms in (e.g., magnifies) the visual representation displayed at the field of view representation  608   a . In response to detecting a left swipe gesture on magnifier user interface object  608   b , electronic device  600  zooms out (e.g., de-magnifies) the visual representation displayed at the field of view representation  608   a . In some embodiments, distancing user interface object  608   g  is a toggle that causes electronic device  600  to activate a distancing feature in response to a first user input (e.g., when toggle is in an inactive position) and causes electronic device to deactivate the distancing feature in response to a second user input (e.g., when toggle is in an active position). 
     At  FIG.  6 B , electronic device  600  detects user input  650   b  (e.g., a tap gesture) on distancing user interface object  608   g . In response to detecting user input  650   b  on distancing user interface object  608   g , electronic device  600  displays distancing user interface  610 , as shown at  FIG.  6 C . In some embodiments, electronic device  600  detects another user input, different from user input  650   b  to cause display of user interface  610 . For example, electronic device  600  can be configured to cause display of user interface  610  in response to detecting a user-specific user input that is set by the user of electronic device  600 . In some embodiments, the user-specific user input includes a gesture on display  602 . In some embodiments, the user-specific user input includes a gesture on side button  604 . Alternatively, electronic device can detect user input  650   c  (e.g., a tap gesture) on settings user interface object  608   h . In response to detecting user input  650   c  on settings user interface object  608   h , electronic device  600  displays user interface  608  with settings menu  608   j , as shown at  FIG.  6 K . 
     At  FIG.  6 C , electronic device  600  displays distancing user interface  610  in response to detecting user input  650   b . Distancing user interface  610  corresponds to a distancing feature of electronic device  600  that provides an indication of a distance between an entity (e.g., a person and/or an object) and electronic device  600  (and thus the user holding electronic device  600 ). The distancing feature of electronic device  600  enables a user to determine a distance between the user and an entity that is detected within a field of view (or a portion of a field of view) of the camera of electronic device  600 . Thus, users that have a vision impairment may utilize electronic device  600  to determine how close an entity is to the device and user as the user holds electronic device  600 . 
     At  FIG.  6 C , distancing user interface  610  includes a field of view representation  612 , which displays a visual representation of a portion of an area surrounding electronic device  600  that is within a field of view of the camera (e.g., of one or more cameras) of electronic device  600 . For example, the camera of electronic device  600  is configured to capture images of an area that is within the field of view of the camera (e.g., an area at which the camera is directed that is based on movement of electronic device  600  by the user). At  FIG.  6 C , field of view representation  612  includes first person  612   a  and second person  612   b  being within a field of view of the camera. At  FIG.  6 C , distancing user interface  610  corresponds to a first mode of the distancing feature of electronic device  600 , as indicated by mode indicator  610   a  of distancing user interface  610 . As discussed in detail below with reference to  FIGS.  6 E- 6 J , distancing user interface  622  corresponds to a second mode of the distancing feature of electronic device  600  as indicated by mode indicator  622   a  of distancing user interface  622 . 
     In the first mode, distancing user interface  610  detects a closest entity (e.g., people and/or objects) to electronic device  600  that is positioned within center portion  614  of field of view representation  612 . For instance, at  FIG.  6 C , center portion  614  of field of view representation  612  is represented by lines  614   a  and  614   b  along display  602  of electronic device  600 . Lines  614   a  and  614   b  indicating center portion  614  are not displayed on distancing user interface  610 , but rather are used for explanatory purposes to show the portions within field of view representation  612  that entities are detected when the distancing feature is active and in the first mode. In some embodiments, lines  614   a  and  614   b  may be closer toward the center of display  602  or away from the center of display  602  to cover a predetermined center portion of field of view representation  612 . For example, in some embodiments, center portion  614  includes 30%, 40%, 50%, 60%, and/or 70% of field of view representation  612  based on a position of lines  614   a  and  614   b  with respect to the center of display  602 . 
     When electronic device  600  operates the distancing feature in the first mode, an entity that is outside of center portion  614  is optionally not detected by electronic device  600  and an indication of distance to an entity that is outside of center portion  614  is not displayed on distancing user interface  610 . At  FIG.  6 C , first person  612   a  is within center portion  614  of field of view representation  612 , but second person  612   b  is outside of center portion  614  of field of view representation  612 . Accordingly, electronic device  600  does not cause display of an indication of distance to second person  612   b  because second person  612   b  is not positioned within center portion  614  of field of view representation  612 . At  FIG.  6 C , second person  612   b  is positioned closer to electronic device  600  (and the user of electronic device  600 ) than first person  612   a . However, because second person  612   b  is not within center portion  614  of field of view representation  612 , electronic device  600  does not display an indication of distance between electronic device  600  and second person  612   b.    
     At  FIG.  6 C , electronic device  600  detects first person  612   a  because first person is the closest entity (e.g., object and/or person) to electronic device  600  that is positioned within center portion  614  of field of view representation  612 . In response to detecting first person  612   a  within center portion  614  of field of view representation  612 , electronic device  600  displays first distance indicator  616  and second distance indicator  618 . First distance indicator  616  and second distance indicator  618  may provide visual confirmation to the user of electronic device  600  that the distancing feature is activated on electronic device  600 . Additionally, electronic device  600  displays distancing feature indicator  610   b  on distancing user interface  610  to indicate that the distancing feature is activated. First distance indicator  616  is a visual representation of a distance between electronic device  600  and first person  612   a . At  FIG.  6 C , first distance indicator  616  is a dashed or dotted line having a start point  616   a  and an end point  616   b . Start point  616   a  represents a position of electronic device  600  (and/or the user of electronic device  600 ) within field of view representation  612 . At  FIG.  6 C , start point  616   a  is positioned above and adjacent to second distance indicator  618  on display  602  as a reference point to indicate the position of electronic device  600  on field of view representation  612 . Displaying start point  616   a  of first distance indicator  616  above and adjacent to second distance indicator  628  facilitates a user&#39;s understanding that first distance indicator  616  and second distance indicator  618  are related (e.g., second distance indicator  618  provides further, textual context for the visual representation of distance provided by first distance indicator  616 ). In some embodiments, start point  616   a  is positioned at the bottom of display  602  and below second distance indicator  618 . 
     End point  616   b  of first distance indicator  616  is displayed as being positioned proximate to (or adjacent to) first person  612   a  within field of view representation  612 . In some embodiments, end point  616   b  is displayed on field of view representation  612  proximate to a portion of first person  612   a  that is detected by electronic device  600  as being closest to electronic device  600 . For example, when first person  612   a  is facing the user of electronic device  600  and sitting down, end point  616   b  can be positioned on field of view representation  612  proximate to a foot of first person  612   a  (e.g., the foot of first person  612   a  is closer to electronic device  600  than other portions of the body of first person  612   a  when first person  612   a  is sitting down and facing the user of electronic device  600 ). In some embodiments, end point  616   b  is positioned within field of view representation  612  at (or near) a mid-point of a body of first person  612   a  and/or another entity that is determined to be the closest distance to electronic device  600  and is within field of view representation  612 . 
     As set forth above, at  FIG.  6 C , first distance indicator  616  includes a dashed and/or dotted line between a detected entity within center portion  614  and electronic device  600 . The dashed and/or dotted line of first distance indicator  616  continuously increases from start point  616   a  to end point  616   b . For example, dots of first distance indicator  616  steadily increase in diameter from start point  616   a  to end point  616   b  (e.g., sequentially). In some embodiments, dashes of first distance indicator  616  steadily increase in thickness and/or length from start point  616   a  to end point  616   b  (e.g., sequentially). In some embodiments, first distance indicator  616  does not increase from start point  616   a  to end point  616   b , but instead maintains a diameter of dots and/or a thickness/length of dashes from start point  616   a  to end point  616   b.    
     At  FIG.  6 C , second distance indicator  618  is a textual representation (e.g., numeric representation) of the distance between first person  612   a  and electronic device  600 . In other words, second distance indicator  618  provides a numeric value of an estimate of distance between first person  612   a  and electronic device  600 . In some embodiments, electronic device  600  estimates the distance between first person  612   a  and electronic device  600  using the camera of electronic device  600 . In some embodiments, electronic device  600  includes multiple cameras and estimates the distance between first person  612   a  and electronic device  600  via parallax analysis with information (e.g., displacement, position, and/or angle information of a detected entity from a line of sight) received from two or more cameras of electronic device  600  to. In some embodiments, electronic device  600  generates a depth map using information (e.g., displacement, position, and/or angle information of a detected entity from a line of sight) received from the two or more cameras of electronic device  600  to estimate the distance between first person  612   a  and electronic device  600 . 
     In some embodiments, electronic device  600  displays second distance indicator  618  with a rounded numerical value of distance (e.g., estimated distance) between first person  612   a  and electronic device  600 . For example, electronic device  600  rounds an estimated distance determined from information received from one or more cameras of electronic device  600  to one or two significant figures. In some embodiments, electronic device  600  rounds the estimated distance to one significant figure when second distance indicator  618  represents a first metric (e.g., feet). In some embodiments, electronic device rounds the estimated distance to two significant figures when second distance indicator  618  represents a second metric (e.g., meters). As set forth below with reference to  FIG.  6 M , electronic device  600  displays second distance indicator  618  with a particular metric (e.g., feet or meters) based on a metric setting selected by user of electronic device  600 . 
     As set forth above, when operating in the first mode of the distancing feature, electronic device  600  detects the closest entity to electronic device  600  within center portion  614  of field of view representation  612 . As such, electronic device  600  forgoes display of first distance indicator  616  and second distance indicator  618  for entities that are detected within center portion  614 , but are determined to be a farther distance from electronic device  600  than a closest entity within center portion  614 . 
     At  FIG.  6 D , first person  612   a  is positioned (e.g., moved) outside of center portion  614  of field of view representation  612  and second person  612   b  remains positioned outside of center portion  614 . Accordingly, electronic device forgoes display of first distance indicator  616  and second distance indicator  618  because no entity is detected within center portion  614  of field of view representation  612  (e.g., between lines  614   a  and  614   b , which are not displayed on distancing user interface  610 ). At  FIG.  6 D , electronic device  600  displays indicator  620  (e.g., “No Person Detected”) indicating that no entity is positioned and/or detected within center portion  614  of field of view representation  612 . In some embodiments, electronic device  600  forgoes display of first distance indicator  616  and second distance indicator  618  and displays indicator  620  when an entity is detected and positioned within center portion  614 , but electronic device  600  determines that the distance between the detected entity and electronic device  600  is beyond a threshold distance (e.g., 10 feet, 15 feet, and/or 20 feet). 
     As set forth above, electronic device  600  can operate using two different modes of the distancing feature. In some embodiments, electronic device  600  switches from the first mode of the distancing feature to the second mode of the distancing feature via user input on mode indicator  610   a  displayed in distancing user interface  610 . In some embodiments, electronic device  600  switches from the first mode of the distancing feature to the second mode of the distancing feature via user input on distancing settings user interface  656 , shown at  FIG.  6 M . In some embodiments, electronic device  600  switches from the first mode of the distancing feature to the second mode of the distancing feature in response to a custom (e.g., user-specified) user input, such as a long press gesture on display  602  when distancing user interface  610  is displayed and/or a single or multi-tap (or multi-press) gesture on side button  604  when distancing user interface  610  is displayed. 
     In response to detecting the user input that causes electronic device  600  to switch from the first mode of the distancing feature to the second mode of the distancing feature, electronic device  600  displays distancing user interface  622 , as shown at  FIG.  6 E . At  FIG.  6 E , the second mode of the distancing feature is activated by electronic device  600  and the first mode of the distancing feature is deactivated by electronic device  600 . Distancing user interface  622  includes indicator  622   b  indicating that the first mode has been deactivated (e.g., “Track Center Person Off”). When operating in the second mode of the distancing feature, electronic device  600  detects a closest entity within any portion of field of view representation  624  of distancing user interface  622  (as opposed to only detecting entities that are positioned within center portion  614  of field of view representation  612 , as described above with reference to  FIGS.  6 C and  6 D ). Accordingly, the second mode of the distancing feature enables a user of electronic device  600  to determine a closest entity to electronic device  600  (and to the user holding electronic device  600 ) within field of view representation  624 , whereas the first mode of the distancing feature enables a user of electronic device  600  to determine a closest entity that is in front of (e.g., positioned in center portion  614  of field of view representation  612 ) electronic device  600  (and in front of the user holding electronic device  600 ). Thus, a user of electronic device  600  may activate the first mode of the distancing feature when walking and/or moving to determine an entity that is closest to the user and in front of the user when walking and/or moving. Alternatively, the user of electronic device  600  may activate the second mode of the distancing feature when stationary (e.g., standing, sitting, and/or laying down) to determine an entity that is closest to the user and within the field of view of a camera of electronic device  600 . 
     At  FIG.  6 E , distancing user interface  622  includes field of view representation  624  that includes first person  624   a  (e.g., first person  612   a ) and second person  624   b  (e.g., second person  612   b ). First person  624   a  and second person  624   b  are both within field of view representation  624 , and because the second mode of the distancing feature is activated, electronic device  600  detects second person  624   b  because second person  624   b  is determined to be closer to electronic device  600  than first person  624   a . When operating in the second mode of the distancing feature, electronic device  600  can detect multiple entities within field of view representation  624 , but optionally displays indicators of distance to the closest detected entity within field of view representation  624  (e.g., without displaying indicators to other entities). The user of electronic device  600  may have the need to determine how far away the user is positioned to the closest entity without needing to determine the distance to entities that are farther away than the closest entity within field of view representation  624 . 
     At  FIG.  6 E , distancing user interface  622  includes first distance indicator  626  and second distance indicator  628 , which both indicate a distance between electronic device  600  and second person  624   b . However, electronic device  600  forgoes display of a distance indicator (e.g., first distance indicator  626  and second distance indicator  628 ) for first person  624   a  because first person  624   a  is determined to be positioned a greater distance away from electronic device  600  than second person  624   b . As set forth above, first distance indicator  626  and second distance indicator  628  provide visual confirmation to the user of electronic device  600  that the distancing feature is activated on electronic device  600 . First distance indicator  626  is a visual representation of a distance between electronic device  600  and first person  624   a . At  FIG.  6 E , first distance indicator  626  is a dashed or dotted line having a start point  626   a  and an end point  626   b . Start point  626   a  represents a position of electronic device  600  (and/or the user of electronic device  600 ) within field of view representation  624 . At  FIG.  6 E , start point  626   a  is positioned above and adjacent to second distance indicator  628  on display  602  as a reference point to indicate the position of electronic device  600  on field of view representation  624 . In some embodiments, start point  626   a  is positioned at the bottom of display  602  and below second distance indicator  628 . 
     End point  626   b  is displayed as being positioned proximate to second person  624   b  within field of view representation  624 . In some embodiments, end point  626   b  is displayed on field of view representation  624  proximate to a portion of second person  624   b  that is detected by electronic device  600  as being closest to electronic device  600 . For example, when second person  624   b  is facing the user of electronic device  600  and sitting down, end point  626   b  can be positioned on field of view representation  624  proximate to a foot of second person  624   b  (e.g., the foot of second person  624   b  is closer to electronic device  600  than other portions of the body of second person  624   b  when second person  624   b  is sitting down and facing the user of electronic device  600 ). In some embodiments, end point  626   b  is displayed at (or near) a midpoint of a body of second person  624   b , as shown at  FIG.  6 E . 
     As set forth above, at  FIG.  6 E , first distance indicator  626  includes a dashed and/or dotted line between a closest detected entity within field of view representation  624  and electronic device  600 . The dashed and/or dotted line of first distance indicator  626  continuously increases from start point  626   a  to end point  626   b . For example, dots of first distance indicator  626  steadily increase in diameter from start point  626   a  to end point  626   b . In some embodiments, dashes of first distance indicator  626  steadily increase in thickness and/or length from start point  626   a  to end point  626   b . In some embodiments, first distance indicator  626  does not continuously increase in diameter and/or thickness/length from start point  626   a  to end point  626   b.    
     At  FIG.  6 E , second distance indicator  628  is a textual representation (e.g., numeric representation) of the distance between second person  624   b  and electronic device  600 . In other words, second distance indicator  628  provides a numeric value of an estimate of distance between second person  624   b  and electronic device  600 . In some embodiments, electronic device  600  estimates the distance between second person  624   b  and electronic device  600  using the camera of electronic device  600 . In some embodiments, electronic device  600  includes multiple cameras and estimates the distance between second person  624   b  and electronic device  600  via parallax analysis with information (e.g., displacement, position, and/or angle information of a detected entity from a line of sight) received from two or more cameras of electronic device  600 . In some embodiments, electronic device  600  generates a depth map using information (e.g., displacement, position, and/or angle information of a detected entity from a line of sight) received from the two or more cameras of electronic device  600  to estimate the distance between second person  624   b  and electronic device  600 . 
     In some embodiments, electronic device  600  displays second distance indicator  628  with a rounded numerical value of distance between second person  624   b  and electronic device  600 . For example, electronic device  600  rounds an estimated distance determined from information received from one or more cameras of electronic device  600  to one or two significant figures. In some embodiments, electronic device  600  rounds the estimated distance to one significant figure when second distance indicator  628  represents a first metric (e.g., feet). In some embodiments, electronic device  600  rounds the estimated distance to two significant figures when second distance indicator  628  represents a second metric (e.g., meters). As set forth below with reference to  FIG.  6 M , electronic device  600  displays second distance indicator  628  (and second distance indicator  618 ) with a particular metric (e.g., feet or meters) based on a metric setting selected by the user of electronic device  600 . 
     At  FIG.  6 E , electronic device  600  displays first distance indicator  626  and second distance indicator  628  to provide an indication of distance between electronic device  600  and second person  624   b  because second person  624   b  is determined to be closest to electronic device  600  (e.g., based on data and/or information received from one or more cameras of electronic device  600 ). At  FIG.  6 F , field of view representation  624  includes first person  624   a , second person  624   b , and third person  624   c  (e.g., third person  624   c  has moved into the field of view of one or more cameras of electronic device). Second person  624   b  is positioned closer to electronic device  600  as compared to the position of second person  624   b  shown in  FIG.  6 E  (e.g., second person  624   b  is positioned 4 feet from electronic device  600  instead of 5 feet from electronic device  600 ). At  FIG.  6 F , second person  624   b  is still the closest entity (e.g., person and/or object) detected within field of view representation  624  to electronic device  600 . Accordingly, distancing user interface  622  includes first distance indicator  626  and second distance indicator  628  that provide an indication of distance between second person  624   b  and electronic device  600 . In addition, electronic device  600  does not display (e.g., forgoes display of) distance indicators that provide an indication of distance between first person  624   a  and/or third person  624   a  because second person  624   b  is determined to be closest to electronic device  600 . 
     At  FIG.  6 F , electronic device  600  causes audio output as shown by audio indicator  630  and haptic output as shown by haptic indicators  632 . In some embodiments, electronic device  600  causes audio output and/or haptic output when an entity within the field of view representation  624  is determined to be positioned within a threshold distance range from electronic device  600  (e.g., positioned at or less than 6 feet from electronic device  600 ). As such, electronic device  600  outputs audio and/or haptics to alert the user of electronic device  600  that an entity is detected as being within the threshold distance range from electronic device  600 . In some embodiments, the audio output shown by audio indicator  630  is an alert that does not include speech (e.g., an alarm sound and/or an audio tone). In some embodiments, the audio output shown by audio indicator  630  includes audio having speech that provides additional information to the user, such as information related to a distance between electronic device  600  and the closest detected entity within field of view representation  624  (e.g., second person  624   b ). As described below with reference to  FIG.  6 M , electronic device  600  adjusts audio output and haptic output based on user inputs detected by electronic device  600  when distancing settings user interface  656  is displayed. 
     At  FIG.  6 G , first person  624   a  and second person  624   b  maintain their respective positions within field of view representation  624  and third person  624   c  is positioned closest to electronic device  600  within field of view representation  624  (e.g., third person  624   c  has moved and/or walked closer to the user holding electronic device  600  or vice versa). At  FIG.  6 G , electronic device  600  adjusts first distance indicator  626  to provide a visual indication of distance between third person  624   c  and electronic device  600  instead of a visual indication of distance between second person  624   b  and electronic device  600  (e.g., because third person  624   c  is detected to be closer to electronic device  600  than second person  624   b ). As such, end point  626   b  of first distance indicator  626  is displayed at a position on field of view representation  624  that is proximate to third person  624   c  instead of second person  624   b . As shown at  FIG.  6 G , electronic device  600  maintains the position of start point  626   a  of first distance indicator  626  at a position above second distance indicator  628 . Accordingly, electronic device  600  moves and/or adjusts first distance indicator  626  to provide the visual indication of distance between the closest entity within field of view representation  624  and electronic device  600 . 
     Also, electronic device  600  updates second distance indicator  628  to provide a textual (e.g., numeric) representation of distance between third person  624   c  and electronic device  600 . As such, second distance indicator  628  provides the textual representation of distance between the closest entity detected within field of view representation  624  and electronic device  600 . Positioning start point  626   a  of first distance indicator  626  directly above second distance indicator  628  facilitates a user&#39;s understanding that second distance indicator  628  is associated with first distance indicator  626  and provides the textual representation of distance between the closest entity detected within field of view representation  624  (e.g., third person  624   c ) and electronic device  600 . 
     At  FIG.  6 G , second distance indicator  628  indicates that third person  624   c  is positioned at a distance closer to electronic device  600  when compared to the distance between second person  624   b  and electronic device  600  in  FIG.  6 F  (e.g., 2 feet instead of 4 feet). At  FIG.  6 G , electronic device  600  outputs audio, as indicated by audio indicator  634 , and outputs haptic feedback, as indicated by haptic indicator  636 . In some embodiments, electronic device  600  maintains audio output and haptic feedback output while displaying distancing user interface  622  (and/or distancing user interface  610 ) and when electronic device  600  determines that an entity in field of view representation  624  is within the threshold distance range (e.g., a distance at or within 6 feet between electronic device  600  and the closest entity within field of view representation  624 ). 
     At  FIG.  6 G , audio indicator  634  indicates that electronic device  600  outputs audio differently when compared to audio indicator  630  of  FIG.  6 F  (e.g., as indicated by two musical notes instead of one musical note) because third person  624   c  is determined to be closer to electronic device  600  in  FIG.  6 G  than second person  624   b  in  FIG.  6 F . In some embodiments, electronic device  600  adjusts audio output based on the determined distance between electronic device  600  and the closest entity within field of view representation  624 . For example, electronic device  600  may increase a volume level of the audio output, increase a frequency of the audio output, and/or increase a pitch of the audio output as the distance between the closest entity within field of view representation  624  and electronic device  600  decreases. Similarly, electronic device  600  may reduce a volume level of the audio output, decrease a frequency of the audio output, and/or decrease a pitch of the audio output as the distance between the closest entity within field of view representation  624  and electronic device  600  increases. As such, users that are vision impaired may listen to the audio output instead of viewing distancing user interface  622  to determine an estimate of a distance between the user and the closest entity within field of view representation  624 . 
     As set forth above, in some embodiments, electronic device  600  causes audio output that includes speech. Electronic device  600  can also adjust the volume level, frequency, and/or pitch of audio output that includes speech based on the determined distance between electronic device  600  and the closest entity within field of view representation  624 . In some embodiments, the audio output that includes speech includes information related to the distance between electronic device  600  and the closest entity detected within field of view representation  624 . For instance, the audio output that includes speech can include voice audio that outputs speech indicating (speaking) the distance between electronic device  600  and the closest entity detected within field of view representation  624 . 
     At  FIG.  6 G , haptics indicator  636  indicates that electronic device  600  outputs haptic feedback differently when compared to haptics indicator  632  of  FIG.  6 F  (e.g., as indicated by an additional mark representing haptic feedback) because third person  624   c  is determined to be closer to electronic device  600  in  FIG.  6 G  than second person  624   b  in  FIG.  6 F . In some embodiments, electronic device  600  adjusts haptic output based on the determined distance between electronic device  600  and the closest entity within field of view representation  624 . For example, electronic device  600  may increase an intensity level of the haptic output, increase a frequency of the haptic output, and/or increase a pitch of the haptic output as the distance between the closest entity within field of view representation  624  and electronic device  600  decreases. Similarly, electronic device  600  may reduce an intensity level of the haptic output, decrease a frequency of the haptic output, and/or decrease a pitch of the haptic output as the distance between the closest entity within field of view representation  624  and electronic device  600  increases. As such, users that are vision impaired may sense (e.g., feel) the haptic output instead of viewing distancing user interface  622  to determine an estimate of a distance between the user and the closest entity within field of view representation  624 . 
     Accordingly, in addition to electronic device  600  displaying first distance indicator  626  and second distance indicator  628 , electronic device  600  is also configured to output audio and/or haptic feedback to provide an indication of distance between electronic device  600  and the closest entity within field of view representation  624 . Thus, users that are vision impaired can sense (e.g., hear and/or feel) the audio and/or haptic feedback to determine an estimated distance between the user and the closest entity within field of view representation  624 . 
     At  FIG.  6 H , field of view representation  624  no longer includes first person  624   a , second person  624   b , and third person  624   c . As such, electronic device  600  does not detect any entity within field of view representation  624 . At  FIG.  6 H , electronic device  600  displays distancing user interface  622  with indicator  622   c  indicating that an entity is not detected within field of view representation  624  (e.g., “No Person Detected”). In some embodiments, electronic device  600  replaces display of second distance indicator  628  with indicator  622   c  and ceases to display first distance indicator  626 . Further, electronic device  600  can cease audio output and haptic output to further indicate to the user of electronic device  600  that an entity is not within field of view representation  624 . 
     As set forth above, in some embodiments, electronic device  600  displays indicator  622   c  on distancing user interface  622  when an entity is within field of view representation  624 , but the entity is determined to be positioned at a distance beyond a threshold distance range (e.g., 10 feet, 15 feet, 20 feet) from electronic device  600 . For instance, even though an entity is displayed and/or detected within field of view representation  624 , electronic device  600  displays indicator  622   c  in response to a determination that the entity is positioned a distance beyond the threshold distance range from electronic device  600 . 
     Turning back to  FIG.  6 F , electronic device  600  detects user input  650   d  on mapping toggle user interface object  638  of distancing user interface  622 . In response to detecting user input  650   d , electronic device  600  displays distancing user interface  622  including mapping user interface object  640 , as shown at  FIG.  6 I . In some embodiments, electronic device  600  does not display mapping user interface object  638  on distancing user interface  622  (and/or distancing user interface  610 ). In some embodiments, electronic device displays distancing user interface object  608   g  instead of mapping user interface object  638 , such that distancing user interface object  608   g  acts as a toggle to activate and deactivate the distancing feature on electronic device  600 . 
     At  FIG.  6 I , field of view representation  624  includes first person  624   a , second person  624   b , and third person  624   c . As set forth above with reference to  FIG.  6 F , electronic device  600  determines that second person  624   b  is the closest entity to electronic device  600  within field of view representation  624 . Thus, distancing user interface  622  includes first distance indicator  626  and second distance indicator  628 , which provide an indication of the distance between second person  624   b  and electronic device  600 . In addition, distancing user interface  622  includes mapping user interface object  640  that provides an indication of distance between electronic device  600  and entities within and/or outside of field of view representation  624 . At  FIG.  6 I , mapping user interface object  640  includes first indicator  640   a  corresponding to a position of electronic device  600  (and thus the user holding electronic device  600 ), second indicator  640   b  corresponding to a position of first person  624   a  with respect to the position of electronic device  600 , third indicator  640   c  corresponding to a position of second person  624   b  with respect to the position of electronic device  600 , and fourth indicator  640   d  corresponding to a position of third person  624   c  with respect to the position of electronic device  600 . 
     Further, mapping user interface object  640  includes first distance ring  640   e  corresponding to a first predetermined distance (e.g., 3 feet) from electronic device  600 , second distance ring  640   f  corresponding to a second predetermined distance (e.g., 6 feet), greater than the first predetermined distance, from electronic device  600 , and third distance ring  640   g  corresponding to a third predetermined distance (e.g., 9 feet), greater than the first and second predetermined distances, from electronic device  600 . First distance ring  640   e , second distance ring  640   f , and third distance ring  640   g  enable a user of electronic device  600  to easily understand a proximity of all detected entities to the user based on the positions of indicators  640   a - 640   d  within first distance ring  640   e , second distance ring  640   f , and third distance ring  640   g.    
     Further still, mapping user interface object  640  includes first field of view indicator  640   h  and second field of view indicator  640   i , which represent a position of field of view indicator  624  on mapping user interface object  640 . Mapping user interface object  640  represents an area surrounding electronic device  600  (and user holding electronic device  600 ) that extends beyond field of view indicator  624 . In some embodiments, mapping user interface object  640  represents an area corresponding to 360 degrees about the position of electronic device  600  (e.g., the position represented by first indicator  640   a ). As such, first field of view indicator  640   h  and second field of view indicator  640   i  enable a user to determine where entities have been detected within field of view representation  624  as well as outside of field of view representation  624 . 
     In some embodiments, mapping user interface object  640  tracks movement of entities detected within field of view representation  624  in real time while field of view representation  624  is displayed  624 , but does not update movement of entities detected outside of field of view representation  624  (e.g., movement of a person that is no longer within field of view representation  624 ). In some embodiments, mapping user interface object  640  tracks movement of entities detected within field of view representation  624  at a predetermined time interval (e.g., every half second, every second, and/or every ten seconds) while field of view representation  624  is displayed  624 , but does not update movement of entities detected outside of field of view representation  624  (e.g., movement of a person that is no longer within field of view representation  624 ). 
     At  FIG.  6 I , electronic device  600  detects user input  650   e  (e.g., a tap gesture) on mapping user interface object  640 . In response to detecting user input  650   e  on mapping user interface object  640 , electronic device  600  displays enlarged mapping user interface object  642 , as shown at  FIG.  6 J . At  FIG.  6 J , enlarged mapping user interface object  642  overlaps and/or at least partially covers field of view representation  624 . Also at  FIG.  6 J , enlarged mapping user interface object  642  includes substantially the same components as mapping user interface object  640  (e.g., components  640   a - 640   i ). Accordingly, a user who is vision impaired may view and comprehend distances between of detected entities, both within the currently displayed field of view representation  624  and outside of the currently displayed field of view representation  624 , and electronic device  600 . At  FIG.  6 J , electronic device  600  detects user input  650   f  (e.g., a tap gesture) on end user interface object  644  of distancing user interface  622 . In response to detecting user input  650   f  on end user interface object  644 , electronic device  600  deactivates the distancing feature, and displays user interface  608 , as shown at  FIG.  6 B . 
     As set forth above, at  FIG.  6 B , electronic device  600  can detect user input  650   c  on settings user interface object  608   h . In response to detecting user input  650   c  on settings user interface object  608   h , electronic device  600  displays settings menu  608   j , as shown at  FIG.  6 K . 
     At  FIG.  6 K , settings menu  608   j  includes general settings user interface object  646 , distancing user interface object  648 , and magnifier user interface object  652 . Electronic device  600  displays distancing user interface  610  and/or distancing user interface  622  in response to detecting user input on distancing user interface object  648 . Additionally, electronic device  600  displays user interface  608  in response to detecting user input on magnifier user interface object  652 . As such, electronic device  600  is configured to activate and deactivate the distancing feature in response to user input on distancing user interface object  648  and magnifier user interface object  652 , respectively. At  FIG.  6 K , electronic device  600  detects user input  650   g  (e.g., a tap gesture) on general settings user interface object  646 . In response to detecting user input  650   g  on general settings user interface object  646 , electronic device  600  displays general settings user interface  654 , as shown at  FIG.  6 L . 
     At  FIG.  6 L , general settings user interface  654  includes first settings area  654   a , second settings area  654   b , filter settings user interface object  656   c , and distancing settings user interface object  656   d . In some embodiments, first settings area  654   a  and second settings area  654   b  correspond to user interface objects that electronic device  600  is configured to display on user interface  608 . As such, electronic device  600  can display and/or cease to display user interface objects on user interface  608  in response to detecting user input in first settings area  654   a  and/or second settings area  654   b . At  FIG.  6 L , electronic device  600  detects user input  650   h  (e.g., a tap gesture) on distancing settings user interface object  656   d . In response to detecting user input  650   h , electronic device  600  displays distancing settings user interface  656 , as shown at  FIG.  6 M . 
     At  FIG.  6 M , distancing settings user interface  656  includes metric settings area  658 , mode settings area  660 , and feedback settings area  662 . Metric settings area  658  includes first metric user interface object  658   a  (e.g., “Meters”) and second metric user interface object  658   b  (e.g., “Feet”). At  FIG.  6 M , distancing settings user interface  656  includes indicator  658   c  indicating that the second metric corresponding to second metric user interface object  658   b  is currently selected and/or activated. As set forth above, electronic device  600  can adjust a metric that is indicated by second distance indicator  618  and second distance indicator  628  in response to detecting user input on first metric user interface object  658   a  and/or second metric user interface object  658   b . Further, electronic device  600  may round a numerical value indicated by second distance indicator  618  and second distance indicator  628  differently based on whether user input is detected on first metric user interface object  658   a  or second metric user interface object  658   b . For example, electronic device  600  can display second distance indicator  618  and second distance indicator  628  with a numeric value indicating an estimated distance rounded to two significant figures in response to detecting user input on first metric user interface object  658   a . Electronic device  600  can display second distance indicator  618  and second distance indicator  628  with a numeric value indicating an estimated distance rounded to one significant figure in response to detecting user input on second metric user interface object  658   b . In some embodiments, electronic device  600  may display second distance indicator  618  and second distance indicator  628  with a numeric value indicating an estimated distance rounded to the same significant figure regardless of whether first metric user interface object  658   a  or second metric user interface object  658   b  is selected. 
     Mode settings area  660  includes first mode user interface object  660   a  corresponding to the first mode of the distancing feature of electronic device  600  and second mode user interface object  660   b  corresponding to the second mode of the distancing feature of electronic device  600 . At  FIG.  6 M , distancing settings user interface  656  includes indicator  660   c  indicating that the first mode of the distancing feature associated with first mode user interface object  660   a  is selected and/or activated. As set forth above, the first mode of the distancing feature of electronic device  600  detects an entity that is closest to electronic device  600  within center portion  614  of field of view representation  612 . The second mode of the distancing feature of electronic device  600  detects an entity that is closest to electronic device  600  that is positioned at any location within field of view representation  624 . Accordingly, electronic device  600  displays distancing user interface  610  when first mode user interface object  660   a  is selected and/or activated and displays distancing user interface object  622  when second mode user interface object  660   b  is selected and/or activated. 
     Feedback settings area  662  includes sounds user interface object  662   a  (e.g., a first toggle) corresponding to activating or deactivating first audio output that does not include speech by electronic device  600  when the distancing feature is activated. Feedback settings area  662  also includes speech user interface object  662   b  (e.g., a second toggle) corresponding to activating or deactivating second audio output that does include speech by electronic device  600  when the distancing feature is activated. Further, feedback settings area  662  includes haptics user interface object  662   c  (e.g., a third toggle) corresponding to activating or deactivating haptic feedback by electronic device  600  when the distancing feature is activated. As set forth above, in some embodiments, electronic device  600  outputs first audio output, second audio output, and/or haptics feedback when an entity detected by electronic device (e.g., within center portion  614  of field of view representation  612  and/or within field of view representation  624 ) is determined to be within a distance threshold range (e.g., 6 feet) from electronic device  600 . Further, as set forth above, electronic device  600  is configured to adjust output of the first audio output, the second audio output, and/or haptics feedback based on the determined distance between the detected entity and electronic device  600 . 
       FIG.  7    is a flow diagram illustrating a method for providing an indication of distance to an entity using computer system in accordance with some embodiments. Method  700  is performed at a computer system (e.g.,  100 ,  300 ,  500 ,  600 ) (e.g., a smart device, such as a smartphone or a smartwatch; and/or a mobile device) that is in communication with one or more cameras (e.g., one or more cameras (e.g., dual cameras, triple cameras, quad cameras, etc.) on the same or different sides of the computer system (e.g., front cameras, back cameras)) and a display generation component (e.g., a display, and/or a touch screen). Some operations in method  700  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     The computer system (e.g.,  600 ) displays ( 702 ), via the display generation component, a visual representation (e.g.,  612 ,  624 ) of a field of view of (e.g., a first camera of) the one or more cameras (e.g., a viewfinder, a live viewfinder, and/or a visual representation of a portion of an area and/or scene surrounding the computer system that is currently within a field of view of the one or more cameras). 
     In some embodiments, the computer system detects (e.g., via the one or more cameras, via a depth of field camera/sensor) an entity (e.g., a person and/or an object (e.g., a non-person)) within the field of view of the one or more cameras. 
     In some embodiments, the computer system determines (e.g., in response to detecting the entity in the field of view; and/or subsequent to detecting the entity in the field of view) a distance (e.g., from the computer system) to the entity. In some embodiments, the distance is determined via parallax between two (or more) cameras of the one or more cameras and/or via a depth map generated via one or two (or more) cameras of the one or more cameras. 
     In accordance with ( 704 ) a determination that an entity (e.g.,  612   a ,  612   b ,  612   c ) meets a set of detection criteria, the set of detection criteria including a first criterion that is met when the entity is detected within the field of view of the one or more cameras, the computer system (e.g.,  600 ) provides ( 706 ), concurrently with the visual representation (e.g.,  612 ,  624 ) of the field of view that includes the entity (e.g., concurrently with the detected entity in the visual representation of the field of view of the one or more cameras; and/or overlaid on the visual representation of the field of view), one or more indicators of distance between the computer system and the entity, wherein providing the one or more indicators of distance includes: displaying, via the display generation component, a visual distance indicator (e.g.,  616 ,  618 ,  626 ,  628 ) (e.g., a line (e.g., a dashed line or solid line) that includes a length indicative of the distance, and/or a numeric value indicative of the distance) that indicates the distance between the computer system and the entity; and In some embodiments, the visual distance indicator includes a numeric value that corresponds to the distance between the detected entity and the computer system, such as a numeric value that is rounded to within one or two significant figures. In some embodiments, the computer system detects a plurality of entities concurrently within the field of view of the one or more cameras and displays the visual distance indicator for only the closest detected entity of the plurality of detected entities. 
     In accordance with ( 708 ) a failure to determine that an entity meets the set of detection criteria (e.g., a determination that no entity is detected that meets the set of detection criteria), the computer system (e.g.,  600 ) forgoes providing ( 710 ) the one or more indicators of a distance between the computer system and the entity. 
     In some embodiments, the one or more indicators of distance varies over time as (e.g., in conjunction with) the distance between the computer system and the entity varies over time. 
     Providing indicators (including a visual indicator) of distance between the computer system and the entity when a set of conditions is met for the entity provides the user with feedback about the distance to the entity, better enabling the user of the computer system to safely navigate their environment in relation to the entity. For example, the user may want to avoid running into objects or may want to stay a healthy distance from other people to reduce the risk of infection, such as through social distancing. This feedback is particularly relevant when the user of the computer system has sight limitations. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user better understand their environment, provide proper inputs, and reduce user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, providing ( 706 ) the one or more indicators of the distance includes: providing (e.g., outputting via an audio output at a speaker of the computer system and/or transmitting to wireless headphones in communication with the computer system for audio output) an audio distance indicator output (e.g.,  630 ,  634 ) that changes based on the distance between the computer system and the entity. 
     Providing indicators (including an audio indicator) of distance between the computer system and the entity when a set of conditions is met for the entity provides the user with feedback about the distance to the entity, better enabling the user of the computer system to safely navigate their environment in relation to the entity. For example, the user may want to avoid running into objects or may want to stay a healthy distance from other people to reduce the risk of infection, such as through social distancing.

     In some embodiments, the audio changes over time as the distance between the computer system and the entity changes, the audio being based on the current distance. In some embodiments, the audio is continuous. In some embodiments, the audio is recurring. 
     In some embodiments, a pitch of the audio distance indicator output (e.g.,  630 ,  634 ) becomes higher as the distance between the computer system and the entity decreases, a frequency (e.g., rate of beeps/sound and/or how often a repeating sound is produced) of the audio distance indicator output (e.g.,  630 ,  634 ) becomes higher as the distance between the computer system and the entity decreases, or (optionally, and) a volume (e.g., loudness) of the audio distance indicator output (e.g.,  630 ,  634 ) increases as the distance between the computer system and the entity decreases. 
     In some embodiments, a pitch of the audio distance indicator output becomes higher as the distance between the computer system and the entity decreases. 
     Providing indicators (including an audio indicator) of change in distance between the computer system and the entity when a set of conditions is met for the entity provides the user with feedback about the distance to the entity, better enabling the user of the computer system to safely navigate their environment in relation to the entity. For example, the user may want to avoid running into objects or may want to stay a healthy distance from other people to reduce the risk of infection, such as through social distancing.

     In some embodiments, the pitch of the audio distance indicator output changes based on the distance between the computer system and the entity. In some embodiments, the pitch becomes lower as the distance between the computer system and the entity increases. In some embodiments, the pitch remains constant as the distance between the computer system and the entity remains constant. 
     In some embodiments, a frequency (e.g., rate of beeps/sound and/or how often a repeating sound is produced) of the audio distance indicator output becomes higher as the distance between the computer system and the entity decreases. 
     Providing indicators (including an audio indicator) of change in distance between the computer system and the entity when a set of conditions is met for the entity provides the user with feedback about the distance to the entity, better enabling the user of the computer system to safely navigate their environment in relation to the entity. For example, the user may want to avoid running into objects or may want to stay a healthy distance from other people to reduce the risk of infection, such as through social distancing.

     In some embodiments, the frequency of the audio distance indicator output changes based on the distance between the computer system and the entity. In some embodiments, the frequency becomes lower as the distance between the computer system and the entity increases. In some embodiments, the frequency remains constant as the distance between the computer system and the entity remains constant. 
     In some embodiments, a volume (e.g., loudness) of the audio distance indicator output increases as the distance between the computer system and the entity decreases. 
     Providing indicators (including an audio indicator) of change in distance between the computer system and the entity when a set of conditions is met for the entity provides the user with feedback about the distance to the entity, better enabling the user of the computer system to safely navigate their environment in relation to the entity.

     In some embodiments, the volume of the audio distance indicator output changes based on the distance between the computer system and the entity. In some embodiments, the volume reduces as the distance between the computer system and the entity increases. In some embodiments, the volume remains constant as the distance between the computer system and the entity remains constant. 
     In some embodiments, the audio distance indicator output (e.g.,  630 ,  634 ) includes stereo components, the stereo components including a first audio channel with a first characteristic (e.g., a first volume, a first pitch, a first spatial filter applied) and a second audio channel with a second characteristic (e.g., a second volume, a second pitch, a second spatial filter applied) that is different from the first characteristic, the first characteristic and the second characteristic based on the distance between the computer system and the entity. 
     Providing indicators, such as stereo or spatial audio indicators, of distance between the computer system and the entity when a set of conditions is met for the entity provides the user with feedback about the distance to the entity, better enabling the user of the computer system to safely navigate their environment in relation to the entity. For example, the user may want to avoid running into objects or may want to stay a healthy distance from other people to reduce the risk of infection, such as through social distancing. This feedback is particularly relevant when the user of the computer system has sight limitations. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user better understand their environment, provide proper inputs, and reduce user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the first audio channel (e.g., left channel) is different from the second audio channel (e.g., right audio channel). In some embodiments, the first audio channel and the second audio channel are produced based on a direction and/or location of the entity with respect to the computer system or the user. In some embodiments, the stereo components are generated such that a user of the computer system perceives audio of the audio distance indicator output as originating from a direction that corresponds to a direction of the entity with respect to the computer system or the user. 
     In some embodiments, the stereo component includes spatial audio. Spatial audio includes audio characteristics of sound have been modified (e.g., by applying filters) such that a user (e.g., listener) perceives the sound as being emitted from a particular location in space (e.g., three-dimensional (3D) space). Such techniques can be achieved using speakers, such as headphones, earbuds, or loudspeakers. In some examples, such as when the user is using headphones, a binaural simulation is used to recreate binaural cues that give the user the illusion that sound is coming from a particular location in space. For example, the user perceives the source of the sound as coming from the left of the user. For another example, the user perceives the source of the sound as coming from a particular direction and/or distance relative to the user. For another example, the user perceives the source of the sound as passing by from left to right in front of the user. This effect can be enhanced by using head tracking to adjust the binaural filters to create the illusion that the location of the source of the sound stays static in space with respect to the user and/or tracks the location of the entity in space with respect to the user, even when the user&#39;s head moves or rotates. In some examples, such as when the user is using loudspeakers, a similar effect is achieved by using crosstalk cancellation to give the user the illusion that sound is coming from a particular location in space. 
     In some embodiments, the spatial audio is produced based on a direction and/or location of the entity with respect to the computer system or the user. In some embodiments, the spatial audio is generated such that a user of the computer system perceives audio of the audio distance indicator output as originating from a direction and/or location (e.g., direction, distance, and/or height) that corresponds to the entity with respect to the computer system or the user. 
     In some embodiments, the audio distance indicator output verbally indicates that the entity (e.g., a person) is detected and/or the distance to the entity. 
     In some embodiments, providing ( 706 ) the one or more indicators of the distance includes: providing a tactile distancing indicator output (e.g.,  632 ,  636 ) (e.g., via one or more tactile output generators, and/or at a remote device in communication with the computer system, such as a watch logged into the same user account as the computer system) that changes based on the distance between the computer system and the entity. 
     Providing indicators, such as tactile indicators, of distance between the computer system and the entity when a set of conditions is met for the entity provides the user with feedback about the distance to the entity, better enabling the user of the computer system to safely navigate their environment in relation to the entity. For example, the user may want to avoid running into objects or may want to stay a healthy distance from other people to reduce the risk of infection, such as through social distancing. This feedback is particularly relevant when the user of the computer system has sight limitations. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user better understand their environment, provide proper inputs, and reduce user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, a pitch of the tactile distance indictor output (e.g.,  632 ,  636 ) changes (e.g., varies over time) based on the distance (e.g., over time) between the computer system and the entity, a frequency (e.g., characteristic frequency) of the tactile distance indictor output (e.g.,  632 ,  636 ) changes based on the distance between the computer system and the entity, or (optionally, and) a waveform of the tactile distance indictor output changes based on the distance between the computer system and the entity. 
     In some embodiments, a pitch of the tactile distance indictor output changes (e.g., varies over time) based on the distance (e.g., over time) between the computer system and the entity. 
     Providing indicators, such as tactile indicators, of change in distance between the computer system and the entity when a set of conditions is met for the entity provides the user with feedback about the distance to the entity, better enabling the user of the computer system to safely navigate their environment in relation to the entity.

     In accordance with some embodiments, a frequency (e.g., characteristic frequency) of the tactile distance indictor output changes based on the distance between the computer system and the entity. 
     Providing indicators, such as tactile indicators, of change in distance between the computer system and the entity when a set of conditions is met for the entity provides the user with feedback about the distance to the entity, better enabling the user of the computer system to safely navigate their environment in relation to the entity.

     In accordance with some embodiments, a waveform of the tactile distance indictor output changes based on the distance between the computer system and the entity. 
     Providing indicators, such as tactile indicators, of change in distance between the computer system and the entity when a set of conditions is met for the entity provides the user with feedback about the distance to the entity, better enabling the user of the computer system to safely navigate their environment in relation to the entity.

     In some embodiments, the pitch, frequency, and waveform of the tactile distance indictor output does not change when the distance between the computer system and the entity does not change. 
     In some embodiments, the visual representation of the field of view of (e.g., a first camera of) the one or more cameras is displayed as part of a user interface of a computer application configured to provide (e.g., as a different feature of the computer application) variable magnification (e.g.,  608 ), based on user input, of visual representations of a second field of view of the one or more cameras (e.g., a magnifier application that provides magnification of the second field of view, which is different from (e.g., smaller (and a subset) of) the field of view). In some embodiments, the visual representation of the field of view of the one or more cameras is configured to not be magnified based on user input (e.g., is not user zoomable). 
     Providing indicators of distance between the computer system and the entity when a set of conditions is met for the entity as part of a variable magnification application provides the user with quick access between magnifying nearby objects for reading and determining a distance to entities in the environment, better enabling the user of the computer system to safely navigate their environment in relation to the entity. For example, the user may want to avoid running into objects or may want to stay a healthy distance from other people to reduce the risk of infection, such as through social distancing. This feedback is particularly relevant when the user of the computer system has sight limitations. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user better understand their environment, provide proper inputs, and reduce user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the set of detection criteria includes a second criterion that is met when a social distancing feature is active. While the social distancing feature is not active, the computer system (e.g.,  600 ) displays a selectable social distancing icon (e.g.,  608   g ) (e.g., to set the social distancing feature to active). The computer system (e.g.,  600 ) receives selection of (e.g.,  650   b , a tap input on) the selectable social distancing icon. In response to receiving selection of the selectable social distancing icon, the computer system (e.g.,  600 ) sets the social distancing feature to active. 
     Providing the user with a mechanism to turn on or of the feature to detect and provide indicators of distance between the computer system and entities enables the computer system to avoid the extra processing of entity detection and providing user feedback when the feature is not desired, thereby reducing power usage and improving battery life. 
     In some embodiments, the computer system monitors for when the social distancing feature is active and does not monitor for entities when the social distancing feature is not active. In response to detecting selection of the selectable social distancing icon, the computer system optionally displays the representation of the field of view of the one or more cameras, determines whether entity(ies) in the field of view meet the set of detection criteria, and (when an entity meets the set of detection criteria) provides the one or more indicators of the distance to the user (e.g., via the displayed visual distance indicator, via the audio distance indicator output, and/or via the tactile distance indictor output). In some embodiments, prior to detecting selection of the selectable social distancing icon, the computer system does not monitor the field of view of the one or more cameras for entities (whether the first portion or any other portion) and/or does not provide the one or more indicators of distance (e.g., visual distance indicator, audio distance indicator output, and/or tactile distance indictor output) to the user about entities within the field of view. 
     In some embodiments, the set of detection criteria includes a third criterion that is met when a social distancing feature is active. The computer system (e.g.,  600 ) receives one or more inputs (e.g., user inputs) that specify a respective user input (e.g., a touch gesture, a three-finger tap input, a three-finger double-tap input, a double- or triple-press of a button of the computer system) to activate the social distancing feature. Subsequent to the respective user input being specified, the computer system (e.g.,  600 ) detects (e.g., in any of various user interface, independent of the application currently displayed, independent of the content currently displayed, and/or while displaying a field of view of one or more cameras) a user input. In response to receiving the user input: in accordance with a determination that the user input corresponds to the respective user input (e.g.,  650   a ), the computer system (e.g.,  600 ) activates the social distancing feature and in accordance with a determination that the user input does not correspond to the respective user input, the computer system (e.g.,  600 ) forgoes activating the social distancing feature. 
     Enabling the user to define a gesture to activate monitoring of entities in the field of view of the computer system enables the computer system to activate the monitoring without the need to navigate a complex hierarchy of user interfaces. Reducing the number of inputs needed to perform an operation enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the computer system can receive user input to configure/specify what input will cause the computer system to start monitoring for social distancing/begin detecting for entities and/or providing the user with feedback about detected entities. 
     In some embodiments, the computer system (e.g.,  600 ) receives user configuration input (e.g., selection of settings) for setting one or more parameters (e.g.,  658 ,  660 ,  662 ) (enabling, disabling, changing characteristics of) for providing the distance between the computer system and the entity. In response to receiving the user configuration input, the computer system (e.g.,  600 ) sets one or more parameters for providing the distance between the computer system and the entity. 
     In some embodiments, setting one or more parameters for providing the distance between the computer system and the entity includes: in accordance with a determination that the user configuration input corresponds to selection of a unit of length (e.g., meters, feet) (e.g.,  658 ) of the visual distance indicator, displaying a distance using the unit of length (e.g.,  618 ,  628 ) as part of displaying the visual distance indicator. 
     Configuring the computer system to provide desired output about distance improves the feedback provided to the user. Providing improved feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, setting one or more parameters for providing the distance between the computer system and the entity includes: in accordance with a determination that the user configuration input corresponds to enabling an audio indication of the distance (e.g.,  662   a ,  662   b ), configuring the computer system to provide (e.g., outputting via an audio output at a speaker of the computer system and/or transmitting to wireless headphones in communication with the computer system for audio output) an audio distance indicator output (e.g.,  630 ,  634 ) that changes based on the distance as part of providing the one or more indicators of the distance, and in accordance with a determination that the user configuration input corresponds to disabling the audio indication of the distance (e.g.,  662   a ,  662   b ), configuring the computer system (e.g.,  600 ) to not provide (e.g., outputting via an audio output at a speaker of the computer system and/or transmitting to wireless headphones in communication with the computer system for audio output) the audio distance indicator output that changes based on the distance as part of providing the one or more indicators of the distance. 
     Configuring the computer system to provide desired output about distance improves the feedback provided to the user. Providing improved feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the audio distance indicator output includes non-speech audio and/or speech audio, which can optionally be individually enabled or disabled via the user configuration input. 
     In some embodiments, setting one or more parameters for providing the distance between the computer system and the entity includes: in accordance with a determination that the user configuration input corresponds to enabling a tactile indication of the distance (e.g.,  662   c ), configuring the computer system to provide a tactile distancing indicator output (e.g.,  632 ,  636 ) (e.g., via one or more tactile output generators, and/or at a remote device in communication with the computer system, such as a watch logged into the same user account as the computer system) that changes based on the distance between the computer system and the entity as part of providing the one or more indicators of the distance; and in accordance with a determination that the user configuration input corresponds to disabling the tactile indication of the distance (e.g.,  662   c ), configuring the computer system to not provide the tactile distancing indicator output (e.g., via one or more tactile output generators, and/or at a remote device in communication with the computer system, such as a watch logged into the same user account as the computer system) that changes based on the distance between the computer system and the entity as part of providing the one or more indicators of the distance. 
     Configuring the computer system to provide desired output about distance improves the feedback provided to the user. Providing improved feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in accordance with a determination that the computer system (e.g.,  600 ) is operating in a first detection mode, the set of detection criteria includes a center entity criterion (e.g., as in  FIG.  6 C ) and in accordance with a determination that the computer system is operating in a second detection mod, the set of detection criteria includes a closest entity criterion that is different from the center entity criterion (e.g., as in  FIG.  6 E ). 
     Operating in different modes enables the computer system to provide the user with distance information that is most relevant to the user&#39;s environment. For example, a user who is traversing an area may benefit more from information about entities that are in their path ahead of them while a user who is stationary may benefit more from information about entities both directly in front and not directly in front of them. Providing improved feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, when the computer system operating in the first detection mode, the set of detection criteria does not include the closest entity criterion. In some embodiments, when the computer system is operating in the second detection mode, the set of detection criteria does not include the center entity criterion. 
     In some embodiments, the center entity criterion is met when the entity (e.g.,  624   a ,  624   b ,  624   c ) is determined to be in a center of the representation of the field of view (e.g., the center of the representation of the field of view overlapping at least a portion of the entity displayed as part of the representation, and/or regardless of whether an entity closer to the computer system is detected, a center portion of representation of the field of view of the one or more cameras) of the one or more cameras. In some embodiments, the center of the representation of the field of view excludes peripheral portions of the representation of the field of view. In some embodiments, the center criterion is met for an entity when the entity is the closest detected entity in the center of the representation. 
     In some embodiments, the center criterion is not met for entities that are not determined to be in the center of the representation of the field of view and, as a result, the computer system forgoes providing the one or more indicators of distance between the computer system and entities not in the center of the representation of the field of view. 
     Operating in different modes enables the computer system to provide the user with distance information that is most relevant to the user&#39;s environment. For example, a user who is traversing an area may benefit more from information about entities that are in their path ahead of them while a user who is stationary may benefit more from information about entities both directly in front and not directly in front of them. Providing improved feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the set of detection criteria includes the center entity criterion. 
     In some embodiments, the closest entity criterion is met when the entity (e.g.,  624   a ,  624   b ,  624   c ) is determined to be a closest entity in the representation of the field of view of the one or more cameras to the computer system (e.g., independent of where in the field of view or the representation of the field of view the entity is located). 
     In some embodiments, the closest entity criterion is not met for entities that are not determined to be the closest entity (to the computer system) in the representation of the field of view and, as a result, the computer system forgoes providing the one or more indicators of distance between the computer system and those entities. In some embodiments, the computer system provides the indications of distance for only the closet entity and not for other entities. 
     Operating in different modes enables the computer system to provide the user with distance information that is most relevant to the user&#39;s environment. For example, a user who is traversing an area may benefit more from information about entities that are in their path ahead of them while a user who is stationary may benefit more from information about entities both directly in front and not directly in front of them. Providing improved feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the set of detection criteria includes the closest entity criterion. 
     In some embodiments, the computer system (e.g.,  600 ) receives user input (e.g., on  66 ) to change the operating mode. In response to receiving the user input to change the operating mode: in accordance with a determination that the user input to change the operating mode corresponds to a request to operate in the first detection mode, configuring the computer system (e.g.,  600 ) to operate in the first detection mode and in accordance with a determination that the user input to change the operating mode corresponds to a request to operate in the second detection mode, configuring the computer system (e.g.,  600 ) to operate in the second detection mode. 
     Operating in different modes enables the computer system to provide the user with distance information that is most relevant to the user&#39;s environment. For example, a user who is traversing an area may benefit more from information about entities that are in their path ahead of them while a user who is stationary may benefit more from information about entities both directly in front and not directly in front of them. Providing improved feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the computer system (e.g.,  600 ) displays, via the display generation component (e.g., concurrently with the visual distance indicator, concurrently with (e.g., overlaid on) the visual representation of a field of view), a (e.g., concentric, circular) graphical element (e.g.,  640 ) (e.g., a radar-style view, a top down view) that includes (e.g., one or more) indications (e.g.,  640   b - 640   d ) of entities (e.g., all entities, all persons and not non-persons) detected in the field of view of the one or more cameras, independent of whether the entities meet the set of detection criteria, wherein the locations of the displayed indications of respective entities on the graphical element are based on a distance from the computer system to the respective entities and a direction from the computer system to the respective entities. In some embodiments, the distances among the displayed indications of respective entities on the graphical element is based on (e.g., representative of) distances among the respective entities. In some embodiments, the displayed indications of respective entities are dots or circles. In some embodiments, the graphical element includes a location (e.g., identified by a visual marker, and/or a center of the graphical element) corresponding to the computer system and distances between the location corresponding to the computer system and the indications of respective entities are based on (e.g., are proportional to) determined distances between the computer system and the respective entities. 
     Providing a radar-style view that includes visual representations of multiple (e.g., all) detected entities enables the computer system to provide the user with a more comprehensive view of the user&#39;s environment. For example, a user who wants to traverse an area may benefit from information about the location of multiple entities in the area. Providing improved feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, a selectable option is displayed which, when activated, causes display of the graphical element that includes indications of entities detected in the field of view. 
     In some embodiments, the computer system (e.g.,  600 ) receives selection of (e.g.,  650   e , tap on) the graphical element (e.g.,  640 ) that includes (e.g., one or more) indications of entities. In response to receiving selection of the graphical element that includes indications of entities, the computer system (e.g.,  600 ) enlarges the graphical element (e.g.,  640 ) and displays the enlarged graphical element overlaid on the representation of the field of view (as shown in  FIG.  6 J ). 
     Providing an enlarged radar-style view that includes visual representations of multiple (e.g., all) detected entities enables the computer system to provide the user with a more easily visually understandable view of the user&#39;s environment. For example, a user who wants to traverse an area may benefit from information about the location of multiple entities in the area. Providing improved feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in accordance with a failure to determine that an entity meets the set of detection criteria (e.g., as in  FIGS.  6 D and  6 H ) (e.g., a determination that no entity is detected that meets the set of detection criteria), the computer system (e.g.,  600 ) displays, via the display generation component (e.g., concurrently with the visual representation of the field of view of the one or more cameras), an indication (e.g.,  620 ,  622   c ) that no entity meets the set of detection criteria (e.g., display “No persons found”). 
     Providing an indication that no entities meet the detection criteria provides the user with feedback about the user&#39;s surroundings. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the set of detection criteria includes a maximum distance criterion that is met when the entity is within a threshold distance from the computer system (e.g., within 15 feet from the computer system). Thus, in some embodiments, persons that are more than the threshold distance from the computer system do not meet the detection criteria and a distance for the person is not displayed. 
     Limiting the feedback to entities that are within a threshold distance from the computer system provides the user with feedback about the user&#39;s more immediate surroundings. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the visual distance indicator (e.g.,  616 ,  626 ) is displayed overlaid on the representation of the field of view and the visual distance indicator includes a linear object (e.g., a line, a solid line, a dotted line) that includes an endpoint (e.g.,  616   b ,  626   b ) that is adjacent to (or overlaid on) the entity (e.g., to the person, to the feet of the person) displayed in the representation of the field of view. 
     Providing a linear object (e.g., a line) that extends to the entity provides the user with feedback about which entity in the field of view provided distance information corresponds to. This is particularly helpful for the user when multiple entities are displayed in the representation of the field of view, but distances are provided for only a subset (e.g., one) of the entities. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, a second endpoint of the linear object is adjacent to a numerical representation of the distance between the computer system to the entity. 
     In some embodiments, the visual representation  612 ,  624 ) of the field of view of the one or more cameras includes an indicator (e.g.,  610   b ) that indicates that the computer system is currently configured to display the visual distance indicator that indicates the distance between the computer system and the entity in accordance with a determination that the entity meets a set of detection criteria. In some embodiments, the computer system (e.g.,  600 ) displays a second visual representation of the field of view of the one or more cameras that: in accordance with a determination that the computer system, while displaying the second visual representation of the field of view of the one or more cameras, is currently configured to display the visual distance indicator that indicates the distance between the computer system and the entity in accordance with a determination that the entity meets a set of detection criteria, includes the indicator (e.g.,  610   b ) that indicates that the computer system is currently configured to display the visual distance indicator that indicates the distance between the computer system and the entity in accordance with a determination that the entity meets a set of detection criteria; and in accordance with a determination that the computer system, while displaying the second visual representation of the field of view of the one or more cameras, is not currently configured to display the visual distance indicator that indicates the distance between the computer system and the entity in accordance with a determination that the entity meets a set of detection criteria, does not include the indicator that indicates that the computer system is currently configured to display the visual distance indicator that indicates the distance between the computer system and the entity in accordance with a determination that the entity meets a set of detection criteria. 
     In some embodiments, while displaying the representation of the field of view, displaying, via the display generation component, an indication overlaid on the field of view that indicates a social distancing feature (e.g., the computer system is monitoring the field of view of the one or more camera for entities that meet the set of one or more criteria) is activated to detect entities in the field of view. 
     Providing the user with a visual indication that the social distancing feature is activated provides the user with feedback about the state of the computer system and whether the computer system will provide alerts/distances as entities come near. Providing improved feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the computer system provides the user with visual feedback that the computer system is monitoring for social distancing and/or attempting to detect entities to provide distance feedback for entities that meet the set of distance criteria. 
     In some embodiments, while displaying the representation of the field of view and monitoring the field of view of the one or more camera for entities that meet the set of one or more criteria: the computer system (e.g.,  600 ) displays, via the display generation component, a toggle (e.g.,  608   g ,  644 ) (or button). The computer system (e.g.,  600 ) receives selection (e.g.,  650   f ) of the toggle. In response to receiving selection of the toggle (and in accordance with a determination that the computer system was monitoring the field of view of the one or more camera for entities that meet the set of one or more criteria when selection of the toggle was received), the computer system (e.g.,  600 ) ceases monitoring the field of view of the one or more camera for entities that meet the set of one or more criteria. 
     Ceasing monitoring of the field of view for entities in response to user input provides the user with a mechanism to reduce processing when entity detection is not required, thereby reducing power usage and improving the battery life of the device. 
     In some embodiments, in response to receiving selection of the toggle, and in accordance with a determination that the computer system was not monitoring the field of view of the one or more camera for entities that meet the set of one or more criteria when selection of the toggle was received, initiating monitoring of the field of view of the one or more camera for entities that meet the set of one or more criteria. 
     In accordance with some embodiments, the set of detection criteria includes a person detection criterion that is met when the entity is (e.g., determined to be) a person (e.g., not an animal, and/or not a non-person such as an object). In accordance with some embodiments, the set of detection criteria alternatively includes an object detection criterion that is met when the entity is (e.g., determined to be) an object (e.g., not a person). 
     As described below, method  700  provides an intuitive way for providing an indication of distance to an entity. The method reduces the cognitive burden on a user for determining distances to entities, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to determine distances to entities faster and more efficiently conserves power and increases the time between battery charges. 
     The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the techniques and their practical applications. Others skilled in the art are thereby enabled to best utilize the techniques and various embodiments with various modifications as are suited to the particular use contemplated. 
     Although the disclosure and examples have been fully described with reference to the accompanying drawings, it is to be noted that various changes and modifications will become apparent to those skilled in the art. Such changes and modifications are to be understood as being included within the scope of the disclosure and examples as defined by the claims. 
     As described above, one aspect of the present technology is the gathering and use of data available from various sources to provide a user with an estimate of distance between the user and an entity located within a surrounding of the user. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, twitter IDs, home addresses, data or records relating to a user&#39;s health or level of fitness (e.g., vital signs measurements, medication information, exercise information), date of birth, or any other identifying or personal information. 
     The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to determine information related to the surroundings of the user, such as entities that may be located within proximity to the user. Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. For instance, health and fitness data may be used to provide insights into a user&#39;s general wellness, or may be used as positive feedback to individuals using technology to pursue wellness goals. 
     The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should occur after receiving the informed consent of the users. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of or access to certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country. 
     Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of location services and entity detection, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app. 
     Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user&#39;s privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods. 
     Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, an estimated distance between an electronic device and an entity within a field of view of a camera of the electronic device may be determined and conveyed to a user without using location information associated with the electronic device.
