## Background
FIELD OF THE DISCLOSURE
This relates generally to electronic devices that are capable of detecting one or more attributes relating to user presence at a device.
BACKGROUND OF THE DISCLOSURE
User interaction with devices such as computers and other electronic computing devices has increased significantly in recent years. These devices can be devices such as computers, tablets, televisions, multimedia devices, and the like.
Interaction with such devices can be performed using various input devices, such as touch screen displays, touch-sensitive surfaces, remote controls, mice and other input devices. However, there are instances where user interaction with the computing devices would be enhanced if the user were not required to physically provide input to the computing devices, but rather if the computing devices were to take certain actions autonomously based on user detection. This latter consideration is particularly important where input devices are battery-operated.
SUMMARY OF THE DISCLOSURE
The embodiments described in this disclosure are directed to one or more devices that optionally perform facial identification, gaze determination, audio-based presence detection, distance determination, and presence determination with respect to one or more users of the devices, and one or more actions that the devices optionally perform in response to the above. The full descriptions of the embodiments are provided in the Drawings and the Detailed Description, and it is understood that the Summary provided above does not limit the scope of the disclosure in any way.

DETAILED DESCRIPTION
In the following description of embodiments, reference is made to the accompanying drawings which form a part hereof, and in which it is shown by way of illustration specific embodiments that are optionally practiced. It is to be understood that other embodiments are optionally used and structural changes are optionally made without departing from the scope of the disclosed embodiments.
Exemplary Devices
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 touch pads), 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 or a television with a touch-sensitive surface (e.g., a touch screen display and/or a touch pad). In some embodiments, the device does not have a touch screen display and/or a touch pad, but rather is capable of outputting display information (such as the user interfaces of the disclosure) for display on a separate display device, and capable of receiving input information from a separate input device having one or more input mechanisms (such as one or more buttons, a touch screen display and/or a touch pad). In some embodiments, the device has a display, but is capable of receiving input information from a separate input device having one or more input mechanisms (such as one or more buttons, a touch screen display and/or a touch pad).
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. Further, as described above, it should be understood that the described electronic device, display and touch-sensitive surface are optionally distributed amongst two or more devices. Therefore, as used in this disclosure, information displayed on the electronic device or by the electronic device is optionally used to describe information outputted by the electronic device for display on a separate display device (touch-sensitive or not). Similarly, as used in this disclosure, input received on the electronic device (e.g., touch input received on a touch-sensitive surface of the electronic device) is optionally used to describe input received on a separate input device, from which the electronic device receives input information.
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, a television channel browsing 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 or non-portable devices with touch-sensitive displays, though the devices need not include touch-sensitive displays or displays in general, as described above. FIG. 1A is a block diagram illustrating portable or non-portable multifunction device 100 with touch-sensitive displays 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 (CPU's) 120, peripherals interface 118, RF circuitry 108, audio circuitry 110, speaker 111, microphone 113, input/output (I/O) subsystem 106, other input or control devices 116, and external port 124. Device 100 optionally includes one or more optical sensors 164. Device 100 optionally includes one or more 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).
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'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'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'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 or non-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. 1A 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. Further, the various components shown in FIG. 1A are optionally implemented across two or more devices; for example, a display and audio circuitry on a display device, a touch-sensitive surface on an input device, and remaining components on device 100. In such an embodiment, device 100 optionally communicates with the display device and/or the input device to facilitate operation of the system, as described in the disclosure, and the various components described herein that relate to display and/or input remain in device 100, or are optionally included in the display and/or input device, as appropriate.
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. Access to memory 102 by other components of device 100, such as CPU 120 and the peripherals interface 118, is, optionally, controlled by memory controller 122.
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 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, Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n), 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, 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 or 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 alternate embodiments, input controller(s) 160 are, optionally, coupled to any (or none) of the following: a keyboard, infrared port, 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).
Touch-sensitive display 112 provides an input interface and an output interface between the device and a user. As described above, the touch-sensitive operation and the display operation of touch-sensitive display 112 are optionally separated from each other, such that a display device is used for display purposes and a touch-sensitive surface (whether display or not) is used for input detection purposes, and the described components and functions are modified accordingly. However, for simplicity, the following description is provided with reference to a touch-sensitive display. 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 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 converts 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®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif.
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 (not shown) 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 or non-portable devices.
Device 100 optionally also includes one or more optical sensors 164. FIG. 1A 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 lens, 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, another optical sensor is located on the front of the device so that the user's image is, optionally, obtained for videoconferencing while the user views the other video conference participants on the touch screen display.
Device 100 optionally also includes one or more contact intensity sensors 165. FIG. 1A 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. 1A shows proximity sensor 166 coupled to peripherals interface 118. Alternately, proximity sensor 166 is coupled to input controller 160 in I/O subsystem 106. In some embodiments, the proximity sensor turns off and disables touch screen 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).
Device 100 optionally also includes one or more tactile output generators 167. FIG. 1A 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.
Device 100 optionally also includes one or more accelerometers 168. FIG. 1A shows accelerometer 168 coupled to peripherals interface 118. Alternately, accelerometer 168 is, optionally, coupled to an input controller 160 in I/O subsystem 106. 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 (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) 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 stores device/global internal state 157, as shown in FIGS. 1A 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's various sensors and input control devices 116; and location information concerning the device's location and/or attitude.
Operating system 126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, 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 thresholds 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 and intensities. 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 (lift off) 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 (lift off) 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.

Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). 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 re-arranged in various embodiments. 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 (whether included in device 100 or on a separate device, such as an input device). 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. 1B is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory 102 (in FIG. 1A) 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, peripheral 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, 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 module 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'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 (not shown) 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 includes 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 lift-off (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second lift-off (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 lift-off 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'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 145. 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 and/or touchpads 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 touch-pads; 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 or non-portable multifunction device 100 having a touch screen 112 in accordance with some embodiments. As stated above, multifunction device 100 is described as having the various illustrated structures (such as touch screen 112, speaker 111, accelerometer 168, microphone 113, etc.); however, it is understood that these structures optionally reside on separate devices. For example, display-related structures (e.g., display, speaker, etc.) and/or functions optionally reside on a separate display device, input-related structures (e.g., touch-sensitive surface, microphone, accelerometer, etc.) and/or functions optionally reside on a separate input device, and remaining structures and/or functions optionally reside on multifunction device 100.
The touch screen 112 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 includes 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 one embodiment, 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, head set 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 include the display and the touch-sensitive surface, as described above, but rather, in some embodiments, optionally communicates with the display and the touch-sensitive surface on other devices. Additionally, 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 (such as a television or a set-top box), a navigation device, an educational device (such as a child'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 (CPU's) 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. 1A), 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. 1A). 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 or non-portable multifunction device 100 (FIG. 1A), or a subset thereof. Furthermore, memory 370 optionally stores additional programs, modules, and data structures not present in memory 102 of portable or non-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 or non-portable multifunction device 100 (FIG. 1A) optionally does not store these modules.
Each of the above identified elements in FIG. 3 are, 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 re-arranged 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.
FIG. 4 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 357) for detecting intensity of contacts on touch-sensitive surface 451 and/or one or more tactile output generators 359 for generating tactile outputs for a user of device 300.
Although some of the examples which 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. In some embodiments the touch sensitive surface (e.g., 451 in FIG. 4) has a primary axis (e.g., 452 in FIG. 4) that corresponds to a primary axis (e.g., 453 in FIG. 4) on the display (e.g., 450). In accordance with these embodiments, the device detects contacts (e.g., 460 and 462 in FIG. 4) with the touch-sensitive surface 451 at locations that correspond to respective locations on the display (e.g., in FIG. 4, 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) are used by the device to manipulate the user interface on the display (e.g., 450 in FIG. 4) 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.
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) 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. 1A or touch screen 112 in FIG. 4A) 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'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).
In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., an “up stroke” of the respective press input).
In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90% or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances).
For ease of explanation, the description 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.
FIG. 5 illustrates a block diagram of an exemplary architecture for the device 500 according to some embodiments of the disclosure. In the embodiment of FIG. 5, media content is optionally received by device 500 via network interface 502, which is optionally a wireless or wired connection.

User Interfaces and Associated Processes
Facial Identification
People interact with electronic devices in many ways, such as running applications and performing various tasks. These interactions can be enhanced by identifying the faces of the people interacting with the devices and performing various actions in accordance with the identifications—in some cases, without requiring additional input from the people. The embodiments described below provide ways to enhance the above interactions. Enhancing interactions with a device reduces the amount of time needed by a person to perform operations, and thus reduces the power usage of the device and increases battery life for battery-powered devices.
FIGS. 6A-6D illustrate exemplary ways in which interactions with electronic devices are enhanced based on facial identification in accordance with some embodiments of the disclosure. The embodiments in these figures are used to illustrate the processes described below, including the processes described with reference to FIGS. 7A-7E.
FIG. 6A illustrates an exemplary use configuration for electronic device 600 according to embodiments of the disclosure. In some embodiments, electronic device 600 is optionally device 500 as described above with reference to FIG. 5, including a set top box or other user interface generating device that is in communication with a remote control and a display device. Optionally, electronic device 600 is coupled to a camera 602. Camera 602 is optionally included in electronic device 600; in some embodiments, the camera is external to the electronic device, for example, in a display device to which the electronic device is coupled. In some embodiments, camera 602 optionally corresponds to any one of optical sensor(s) 164 in FIG. 1A and sensors (359) in FIG. 3. Camera 602 optionally includes any type of image sensor, such as a red-green-blue (RGB) image sensor, a depth image sensor, and an infrared (IR) image sensor. Electronic device 600 optionally receives sensed image data from camera 602. In the embodiment illustrated, a first person 604 is located in front of camera 602 such that the camera is able to capture an image of the first person. It is understood that people use devices. When a person uses a device (e.g., device 600), that person is optionally referred to as a user of the device. Thus, in this disclosure, references to a “person” or “people” are optionally interchangeable with references to a “user” or “users”, and references to a “user” or “users” are optionally interchangeable with references to a “person” or “persons”.
FIG. 6B illustrates an exemplary first image 606 provided by camera 602 to electronic device 600. In some embodiments, first image 606 includes first person 604 and other people or things 610. In some embodiments, electronic device 600 identifies the face 608 of first person 604 from first image 606. Identifying the face 608 of first person 604 optionally includes determining the shape and/or location of the face in the image, and not necessarily the identity of the person to whom the face belongs, though both are within the scope of the disclosure. Electronic device 600 optionally performs an action in accordance with the identification of the face 608 of first person 604, as will be described in more detail below.
FIG. 6C illustrates an exemplary action performed by electronic device 600 in accordance with the identification of the face 608 of first person 604. In some embodiments, electronic device 600 generates a user interface for display on a display device, such as a television. In some embodiments, the user interface includes second image 612 that includes the face 614 of a second person 616, where the face 614 of the second person 616 is different from the face 608 of first person 604 (e.g., second image 612 is an image of a person different than first person 604). Electronic device 600 optionally identifies the face 614 of the second person 616 from second image 612. Identifying the face 614 of the second person 616 optionally includes determining the shape and/or location of the face in the image, and not necessarily the identity of the person to whom the face belongs, though both are within the scope of the disclosure. In the illustrated embodiment, electronic device 600 replaces the face 614 of the second person 616 in second image 612 with the face 608 of first person 604 from first image 606, thus providing a simple and automatic way of replacing one person's face with another person's face in an image.
FIG. 6D illustrates another exemplary action performed by electronic device 600 in accordance with the identification of the face 608 of first person 604. As described above, in some embodiments, electronic device 600 generates a user interface 618 for display on a display device, such as a television. User interface 618 optionally includes one or more user interface elements 620, 622 and 624, which optionally include things such as images, buttons, toolbars, media content, icons, application windows, etc. Electronic device 600 optionally determines an orientation of face 608 of first person 604 in first image 606 with respect to the display device. Determining an orientation of face 608 of first person 604 with respect to the display device optionally includes determining whether first person's 604 face 608 aligns with the display device (e.g., the top of the person's face aligns with the top of the display device, the bottom of the person's face aligns with the bottom of the display device, etc.). In some embodiments, electronic device 600 aligns user interface 618 for display on the display device with the orientation of face 608 of first person 604 in first image 606. Aligning user interface 618 optionally includes lining up the user interface with the first person's 604 face 608 by, for example, rotating a user interface element (e.g., image, toolbar, media content, icon, application window, etc.) such that one or more of the top/bottom/left/right of the user interface element align with one or more of the top/bottom/left/right of the face 608 of the first person 604 in the first image 606, as illustrated.
In some embodiments, aligning user interface 618 with the first person's 604 face 608 includes forgoing aligning user interface 618 based on an orientation of the electronic device 600 detected by one or more sensors of the electronic device. For example, even if a mobile phone is being held sideways with respect to gravity as detected by one or more accelerometers or an inertial measurement unit, the mobile phone optionally does not rotate the user interface on the mobile phone if the person in front of the mobile phone is also sideways, e.g., looking at the phone while laying down on his/her side. For example, in some circumstances, the default behavior of the device optionally is to align the user interface so that a bottom edge of the user interface is aligned with the edge of the device that is oriented down (e.g., closest to the floor), but if a face is detected, this default behavior is optionally overridden so that even if a first edge of the device is closest to the floor, the user interface will optionally be aligned with a second edge that causes the user interface to be oriented so that it appears right-side-up for the user.
In some embodiments, the user interface includes a content item being played (e.g., a movie, a television show, a game, a song, a radio show), and performing the action on the electronic device in accordance with the identification of the face of the first person optionally includes associating the playing of the content item with the first person (e.g., tracking the person's viewing or other activity history without requiring the person to manually login to the electronic device, or marking notifications as read by the user only if the user is in front of the display when the notifications are displayed on the display, even if the user is logged in and the device is not asleep). In some embodiments, the electronic device identifies, based on the face of the first person in the first image, a first profile on the electronic device that is associated with the face of the first person (e.g., actually identifying the person). In such embodiments, associating the playing of the content item with the first person optionally includes associating the playing of the content item with the first profile. In some embodiments, the electronic device updates a play count of the content item in the first profile.
In some embodiments, two or more people might be captured in an image taken by the camera. In such instances, the first image optionally further includes a face of a second person. In addition to identifying the face of the first person in the first image, the electronic device optionally identifies the face of the second person from the first image, identifies, based on the face of the second person in the first image, a second profile on the electronic device that is associated with the face of the second person (e.g., actually identifying the second person), and associates the playing of the content item with the second profile. In other words, the electronic device optionally associates the playing of the content item with both the first person and the second person.
In some embodiments, the second person might join the first person after the first person has started playing the content item. In such instances, the electronic device optionally receives a second image including the face of the first person (e.g., a second image including just one person), identifies the face of the first person from the second image, and in response to identifying the face of the first person from the second image, continues to associate the playing of the content item with the first person (e.g., while the face of the first person continues to be detected, continuing to associate the playing of the content item with the first person). The electronic device optionally receives a third image including the face of the first person and a face of a second person (e.g., a third image including both the first person and the second person), where the third image was captured after the second image was captured (e.g., the second person arrives at the display device while the first person is watching the content item). In some embodiments, the electronic device identifies the face of the first person and the face of the second person from the third image (e.g., identifying both people at the display device), and in response to identifying the face of the first person and the face of the second person from the third image, continues to associate the playing of the content item with the first person (e.g., while the face of the first person continues to be detected, continuing to associate the playing of the content item with the first person), and associates the playing of the content item with the second person (e.g., starts associating the playing of the content item with the second person when the face of the second person is identified).
In some embodiments, the electronic device verifies that the first person is identified for longer than a certain time period before finally associating the playing of the content item with the first person. In such instances, as described above, the user interface generated by the electronic device optionally includes a content item being played (e.g., a movie, a television show, a game, a song, a radio show). Performing the action on the electronic device in accordance with the identification of the face of the first person optionally includes making a preliminarily association of the playing of the content item with the first person (e.g., tracking the person's viewing or other activity history without requiring the person to manually login to the electronic device, or marking notifications as read by the user only if the user is in front of the display when the notifications are displayed on the display, even if the user is logged in and the device is not asleep). In some embodiments, the electronic device receives a second image at least a first time threshold (e.g., 1, 15, or 30 seconds) after receiving the first image. After receiving the second image, the electronic device optionally determines whether the second image includes the face of the first person. In accordance with a determination that the second image does not include the face of the first person, the electronic device optionally cancels the preliminary association of the playing of the content item with the first person. In accordance with a determination that the second image includes the face of the first person, the electronic device optionally confirms the preliminary association of the playing of the content item with the first person (e.g., to ensure that first person is “present” for long enough to associate the content item with that person).
FIGS. 7A-7E are flow diagrams illustrating a method 700 of performing an action based in part on identification of a face in an image in accordance with some embodiments (e.g., as described above with reference to FIGS. 6A-6D). The method 700 is optionally performed at an electronic device such as device 500 as described above with reference to FIG. 5, including a set top box or other user interface generating device that is in communication with a remote control and a display device. Some operations in method 700 are, optionally, combined and/or the order of some operations is, optionally, changed.
As described below, the method 700 provides ways in which a device can react to identifying the face of a user. The method reduces the cognitive burden on a user when interacting with a user interface on the device, and reduces the need for the user to physically interact with the device, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, increasing the efficiency of the user's interaction with the user interface conserves power and increases the time between battery charges.
In some embodiments, an electronic device (e.g., a set top box or other user interface generating device that is in communication with a remote control and a display device, such as device 600 in FIG. 6A) with one or more processors and memory generates (702) a user interface for display on a display device (e.g., a television or other display device). In some embodiments, the user interface includes a content item being played (704) (e.g., a movie, a television show, a game, a song, a radio show).
In some embodiments, the device receives (706) a first image including a face of a first person (e.g., an image of the person from an RGB camera, such as image 606 including face 608 in FIG. 6B). In some embodiments, the user interface includes a second image that includes a face of a second person, the face of the second person being different from the face of the first person (708) (e.g., an image of someone other than the first person, such as image 612 including face 614 in FIG. 6C). In some embodiments, the first image further includes a face of a second person (710).
In some embodiments, the device identifies (712) the face of the first person from the first image (e.g., determining the shape/location of the face in the image, not necessarily the identity of the person to whom the face belongs).
In some embodiments, the device performs (714) an action on the electronic device in accordance with the identification of the face of the first person (e.g., displaying the image on the display device with everything but the person's face having some visual effect, logging the person into the electronic device, etc.). In some embodiments, performing the action on the electronic device in accordance with the identification of the face of the first person comprises associating the playing of the content item with the first person (716) (e.g., tracking the person's viewing or other activity history without requiring the person to manually login to the electronic device or marking notifications as read by the user only if the user is in front of the display when the notifications are displayed on the display, even if the user is logged in and the device is not asleep). In some embodiments, performing the action on the electronic device in accordance with the identification of the face of the first person comprises making a preliminarily association of the playing of the content item with the first person (718) (e.g., preliminarily tracking the person's viewing or other activity history without requiring the person to manually login to the electronic device or marking notifications as read by the user only if the user is in front of the display when the notifications are displayed on the display, even if the user is logged in and the device is not asleep).
In some embodiments, the device identifies (720) the face of the second person from the second image (e.g., determining the shape/location of the face in the image, not necessarily the identity of the person to whom the face belongs). In some embodiments, performing the action on the electronic device in accordance with the identification of the face of the first person comprises replacing the face of the second person in the second image with the face of the first person in the first image (722) (e.g., placing the first person's face into an image that has another face, such as replacing face 614 in image 612 with face 608 in FIG. 6C).
In some embodiments, the device determines (724) an orientation of the face of the first person in the first image with respect to the display device (e.g., determining whether the first person's face aligns with the display device). In some embodiments, performing the action on the electronic device in accordance with the identification of the face of the first person comprises aligning the user interface for display on the display device with the orientation of the face of the first person in the first image (726) (e.g., lining up the user interface with the person's face by, for example, rotating a user interface element (e.g., image, toolbar, icon, application window, etc.) such that one or more of the top/bottom/left/right of the user interface element align with one or more of the top/bottom/left/right of the face of the first person in the first image). FIG. 6D and its associated discussion provide an exemplary embodiment in which such aligning is performed. In some embodiments, aligning the user interface with the orientation of the face of the first person comprises forgoing aligning the user interface based on an orientation of the device detected by one or more sensors of the device (728) (e.g., even if a mobile phone is being held sideways with respect to gravity as detected by one or more accelerometers or an inertial measurement unit, the mobile phone not rotate the user interface on the mobile phone if the person in front of the mobile phone is also sideways, e.g., looking at the phone while laying down on his/her side). For example, the default behavior of the device is optionally to align the user interface so that a bottom edge of the user interface is aligned with the edge of the device that is oriented down (e.g., closest to the floor), but if a face is detected, this default behavior is overridden so that even if a first edge of the device is closest to the floor, the user interface will be aligned with a second edge that causes the user interface to be oriented so that it appears right-side-up for a user.
In some embodiments, the device identifies (730), based on the face of the first person in the first image, a first profile on the electronic device that is associated with the face of the first person (e.g., actually identifying the person). In some embodiments, associating the playing of the content item with the first person comprises associating the playing of the content item with the first profile (732). In some embodiments, associating the playing of the content item with the first profile comprises updating a play count of the content item in the first profile (734).
In some embodiments, the device identifies (738) the face of the second person from the first image. In some embodiments, the device identifies (740), based on the face of the second person in the first image, a second profile on the electronic device that is associated with the face of the second person (e.g., identify the second user). In some embodiments, the device associates (742) the playing of the content item with the second profile.
In some embodiments, the device receives (746) a second image including the face of the first person (e.g., a second image including just one person). In some embodiments, the device identifies (748) the face of the first person from the second image. In some embodiments, in response to identifying the face of the first person from the second image, the device continues to associate (750) the playing of the content item with the first person (e.g., while the face of the first person continues to be detected, continue to associate the playing of the content item with the first person). In some embodiments, the device receives (752) a third image including the face of the first person and a face of a second person (e.g., a third image including two people). In some embodiments, the third image was captured after the second image was captured (754) (e.g., the second person arrives at the display device while the first person is watching the content item). In some embodiments, the device identifies (756) the face of the first person and the face of the second person from the third image (e.g., identifying both people at the display device). In some embodiments, in response to identifying the face of the first person and the face of the second person from the third image (758) the device continues to associate (760) the playing of the content item with the first person (e.g., while the face of the first person continues to be detected, continue to associate the playing of the content item with the first person), and the device associates (762) the playing of the content item with the second person (e.g., start associating the playing of the content item with the second person when the face of the second person is identified).
In some embodiments, the device receives (766) a second image. In some embodiments, the second image is received at least a first time threshold after receiving the first image (768) (e.g., 1, 15, or 30 seconds). In some embodiments, after receiving the second image, the device determines (770) whether the second image includes the face of the first person. In some embodiments, in accordance with a determination that the second image does not include the face of the first person, the device cancels (772) the preliminary association of the playing of the content item with the first person. In some embodiments, in accordance with a determination that the second image includes the face of the first person, the device confirms (774) the preliminary association of the playing of the content item with the first person (e.g., ensure that first person is “present” for long enough to associate the content item with them).
It should be understood that the particular order in which the operations in FIGS. 7A-7E have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 900, 1100, 1300 and 1500) are also applicable in an analogous manner to method 700 described above with respect to FIGS. 7A-7E. For example, the user interfaces, display device and content item described above with reference to method 700 optionally have one or more of the characteristics of the user interfaces, display devices and content items (or media content) described herein with reference to other methods described herein (e.g., methods 900, 1100, 1300 and 1500). For brevity, these details are not repeated here.
The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in an information processing apparatus such as general purpose processors (e.g., as described above with respect to FIGS. 1A, 3 and 5) or application specific chips.
The operations described above with reference to FIGS. 7A-7E are, optionally, implemented by components depicted in FIGS. 1A-1B. For example, generation operation 702, receiving operation 706, identification operation 712 and performing operation 714 are, optionally implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B.
Gaze Determination
Determining where in a user interface a person is looking (e.g., gaze location), and performing one or more actions based on that gaze location, can enhance the person's experience when interacting with the user interface. Such a user interface, generated by a device, enables the person to perform certain actions associated with the device without the need to provide physical input, such as through a touch-sensitive surface or a mouse. The embodiments described below describe ways in which determining a person's gaze location in a user interface can enhance that person's experience when interacting with the user interface. Enhancing the usability of a device reduces the amount of time needed by the person to perform operations, and thus reduces the power usage of the device and increases battery life for battery-powered devices.
FIGS. 8A-8E illustrate exemplary ways in which interactions with user interfaces are enhanced based on gaze determination in accordance with some embodiments of the disclosure. The embodiments in these figures are used to illustrate the processes described below, including the processes described with reference to FIGS. 9A-9C.
FIG. 8A illustrates an exemplary user interface 800 according to embodiments of the disclosure. User interface 800 is optionally generated by an electronic device such as device 500 as described above with reference to FIG. 5, including a set top box or other user interface generating device that is in communication with a remote control and a display device. User interface 800 is optionally for display on a display device, such as a television or other display device. In the illustrated embodiment, user interface 800 includes a plurality of user interface elements 802, 804, 806, 808 and 810. The user interface elements are optionally any combination of any user interface elements that can appear in a user interface, such as icons, application windows, buttons, toolbars, media content, docks, etc. Though user interface 800 includes a plurality of user interface elements, it is understood that the processes described here are optionally performed in a user interface including only a single user interface element.
The electronic device described above optionally determines a gaze location 812 in user interface 800. The gaze location 812 is a location in user interface 800 to which a person's gaze is directed. In other words, the electronic device optionally determines where in user interface 800 the person is looking. In making this determination, the electronic device uses any suitable method for determining the gaze location 812, such as identifying the person's eyes and their direction, and the person's distance from the display device, and calculating the gaze location based on those quantities. Other methods of determining the gaze location 812 are similarly within the scope of the disclosure.
Once the electronic device determines the gaze location 812, the electronic device optionally determines whether the gaze location 812 coincides with a user interface element in user interface 800. In other words, the electronic device optionally determines whether the person is looking at a user interface element in user interface 800. In the illustrated embodiment, if the electronic device were determining whether the gaze location 812 coincides with user interface element 806, for example, the electronic device would determine that it does not. If, however, the electronic devise were determining whether the gaze location 812 coincides with user interface element 810, the electronic device would determine that is does.
In accordance with a determination that the gaze location 812 coincides with user interface element 810 (e.g., a determination that the person is looking at user interface element 810), the electronic device optionally performs an action with respect to user interface element 810. Possible actions that the electronic device optionally performs are described in more detail below.
FIGS. 8B-8C illustrate an exemplary action that the electronic device optionally performs based on the gaze location 812 in user interface 800. FIG. 8B illustrates user interface 800, mostly as described above. However, in the embodiment of FIG. 8B, user interface element 806 is requesting the person's attention by, for example, flashing, bouncing, or any other mechanism for requesting the person's attention. User interface element 806 might request the person's attention for many reasons, including but not limited to, requiring the person's input to proceed with an operation (such as installing a program), or providing a notification of an event (such as receipt of a new email) to the person. In the illustrated embodiment, the person is looking at user interface element 802 while user interface element 806 is requesting the person's attention.
In FIG. 8C, the person has started to look at user interface element 806, and thus gaze location 812 has shifted from user interface element 802 to user interface element 806. As illustrated, because the gaze location 812 is now coincident with user interface element 806, electronic device optionally acknowledges user interface element's 806 request for attention, and ceases any mechanism user interface element 806 was utilizing to request the person's attention (e.g., bouncing, flashing).
FIGS. 8D-8E illustrate another exemplary action that the electronic device optionally performs based on the gaze location 812 in user interface 800. FIG. 8D illustrates user interface 800, as described above. In FIG. 8D, gaze location 812 is between the user interface elements in user interface 800.
In FIG. 8E, the person has started to look at user interface element 806, and thus gaze location 812 is coincident with user interface element 806. As a result, electronic device optionally emphasizes user interface element 806 relative to other user interface elements. In other words, the user interface element at which the person is looking is optionally emphasized relative to other user interface elements. In the illustrated example, user interface element 806 is enlarged while the sizes of the remaining user interface elements remain constant. In some implementations, emphasizing a user interface element is accomplished by increasing its brightness relative to other user interface elements, promoting its position in a user interface element z-order, blurring or dimming other user interface elements, changing its position relative to other user interface elements, or any other mechanism for emphasizing the user interface element relative to other user interface elements.
In some embodiments, the electronic device optionally determines one or more portions of the display device that are not coincident with the gaze location and a particular user interface element, and adjusts an output of the one or more portions of the display device that are not coincident with the gaze location. In other words, the electronic device optionally dims or turns off parts of the display device that the person is not looking at.
In some embodiments, a user interface element coincident with the gaze location becomes a selected user interface element. In some embodiments, a particular user interface element includes moving items, such as a stock ticker including scrolling stock quotes. The electronic device optionally determines which of the moving items (e.g., stock quotes) the gaze location coincides with, and the electronic device optionally modifies the movement of the looked-at moving item (e.g., slowing down or stopping the movement) so that the particular moving item is visible in the user interface. For example, when a person looks at a specific stock quote in a scrolling stock quote list, the electronic device optionally stops the scrolling of the stock quotes so that the looked-at stock quote is visible and can be more easily read by the person.
In some embodiments, the user interface element including the moving items is an autoscrolling list, and the moving items are elements of the autoscrolling list. In some embodiments, the user interface element is an image catalog (e.g., a collection of photographs, album artwork, etc.), and the moving items are images in the image catalog. In some embodiments, the user interface element is a content bar (e.g., a channel bar, an application bar, etc.), and the moving items are representations of content items accessible form the content bar (e.g., channels, programs, and apps that are presented to the person in response to detecting activation of a corresponding representation in the content bar).
In some embodiments, a particular user interface element includes content. For example, the user interface element optionally contains text and/or images. In such a circumstance, when the gaze location coincides with the user interface element, the electronic device optionally designates the content in the user interface element as being read. For example, the electronic device optionally tracks when a person has read all portions of a contract (or tracks which portions of the contract the person has read), a message, an email, etc., and when the electronic device determines that the person has read the entire contract/message/email, the electronic device optionally designates the contract/message/email as being read. In some embodiments, the electronic device designates portions of the contract/message/email as being read as they are read by the person.
In some embodiments, the gaze location is used to designate a user interface element as being an active user interface element. For example, if the gaze location is coincident with a particular user interface element, the electronic device optionally designates that particular user interface element as being an active user interface element. Then, when input from an input device (e.g., a mouse) for interacting with an active user interface element is received by the electronic device, the electronic device facilitates interaction with the particular user interface element (e.g., the active user interface element) in accordance with the input. For example, a person optionally designates which of a plurality of application windows the person desires to scroll with a scrolling input on a mouse by, for example, looking at the appropriate application window. The person optionally alters this designation simply by looking at different application windows. Then, the person optionally provides a scrolling input, for example, to the electronic device, and the application window at which the person is looking optionally scrolls in response to the scrolling input.
In some embodiments, the input device has an associated cursor (e.g., mouse pointer) in the user interface. In such circumstances, the electronic device optionally ignores the location of the cursor in designating the user interface element with which the gaze location is coincident as the active user interface element. For example, a scrolling input receiving from a mouse optionally scrolls an application window the person is looking at, and not the application window over which the mouse curser is located.
FIGS. 9A-9C are flow diagrams illustrating a method 900 of performing an action based in part on determining a gaze location in accordance with some embodiments (e.g., as described above with reference to FIGS. 8A-8E). The method 900 is performed at an electronic device such as device 500 as described above with reference to FIG. 5, including a set top box or other user interface generating device that is in communication with a remote control and a display device. Some operations in method 900 are, optionally, combined and/or the order of some operations is, optionally, changed.
As described below, the method 900 provides ways in which a device optionally reacts to determining a gaze location of a user. The method reduces the cognitive burden on a user when interacting with a user interface on the device, and reduces the need for the user to physically interact with the device, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, increasing the efficiency of the user's interaction with the user interface conserves power and increases the time between battery charges.
In some embodiments, an electronic device (e.g., a set top box or other user interface generating device that is in communication with a remote control and a display device) with one or more processors and memory generates (902) a user interface (e.g., user interface 800 in FIG. 8A) for display on a display device (e.g., a television or other display device). In some embodiments, the user interface includes a first user interface element (904) (e.g., an icon, an application window, a button, etc., such as user interface element 806 in FIG. 8A). In some embodiments, the first user interface element comprises a user interface element requesting attention (906) (e.g., a bouncing icon, such as user interface element 806 in FIG. 8B). In some embodiments, the user interface further includes a second user interface element (908) (e.g., the first user interface element is a first application window and the second user interface element is a second application window). In some embodiments, the first user interface element comprises a plurality of moving items (910) (e.g., stock ticker with scrolling stock quotes). In some embodiments, the first user interface element comprises an autoscrolling list, and the plurality of moving items comprise elements of the autoscrolling list (912). In some embodiments, the first user interface element comprises an image catalog (e.g., collection of photographs, album artwork, etc.), and the plurality of moving items comprise images in the image catalog (914). In some embodiments, the first user interface element comprises a content bar (e.g., channel bar, app bar), and the plurality of moving items comprise representations of content items accessible from the content bar (916) (e.g., channels, programs, apps that are presented to the user in response to detecting activation of a corresponding representation in the content bar). In some embodiments, the first user interface element comprises content (918) (e.g., text, images, etc.).
In some embodiments, the device determines (920) a gaze location in the user interface (e.g., gaze location 812 in FIG. 8A). In some embodiments, the gaze location comprises a location in the user interface to which a person's gaze is directed (922) (e.g., the device determines where in the user interface the person is looking; the determination is optionally based on identifying the person's eyes and their direction).
In some embodiments, the device determines (924) whether the gaze location in the user interface coincides with the first user interface element (e.g., the device determines whether the person is looking at the first user interface element, such as whether gaze location 812 coincides with user interface element 806 in FIG. 8B).
In accordance with a determination that the gaze location coincides with the first user interface element (926), in some embodiments, the device performs (928) an action with respect to the first user interface element (e.g., acknowledging a displayed message). In some embodiments, performing the action with respect to the first user interface element comprises acknowledging the request for attention in response to determining that the gaze location coincides with the first user interface element (930) (e.g., the icon stops bouncing, such as acknowledging user interface element 806's request for attention in FIG. 8C). In some embodiments, performing the action with respect to the first user interface element comprises emphasizing the first user interface element relative to the second user interface element (932) (e.g., emphasizing (brightness, blur, size, etc.) the application window that the user is looking at relative to other application window(s) the user is not looking at, such as is illustrated in FIGS. 8D-8E). In some embodiments, performing the action with respect to the first user interface element comprises selecting the first user interface element (934) (e.g., select a user interface element the user is looking at). In some embodiments, performing the action with respect to the first user interface element comprises designating the content in the first user interface element as being read (936) (e.g., track whether a user has read all portions of a contract, message, email, etc.). In some embodiments, performing the action with respect to the first user interface element comprises designating the first user interface element as an active user interface element (938).
In some embodiments, the device determines (940) one or more portions of the display device that are not coincident with the gaze location and the first user interface element. In some embodiments, performing the action with respect to the first user interface element comprises adjusting an output of the one or more portions of the display device that are not coincident with the gaze location (942) (e.g., dimming or turning off parts of the display that the user is not looking at).
In some embodiments, the device determines (944) a first item of the plurality of moving items with which the gaze location coincides. In some embodiments, performing the action with respect to the first user interface element comprises modifying a movement (e.g., slowing down or stopping) of the first item of the plurality of moving items such that the first item is visible in the user interface (946) (e.g., when the user looks at a specific stock quote, stopping the scrolling of the stock quotes so that the looked-at stock quote is visible and can be more easily read by the user).
In some embodiments, the device receives (950) a first input from an input device (e.g., mouse) for interacting with an active user interface element. In some embodiments, a location of a cursor associated with the input device is coincident with the second user interface element (952). In some embodiments, designating the first user interface element as the active user interface element comprises ignoring the location of the cursor in designating the first user interface element as the active user interface element (954) (e.g., scrolling the application window the user is looking at, not the application window over which the cursor is located). In some embodiments, in response to the first input, the device interacts with the first user interface element in accordance with the first input (956) (e.g., the window that the user is looking at will scroll in response to a scroll input received on a mouse).
It should be understood that the particular order in which the operations in FIGS. 9A-9C have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 700, 1100, 1300 and 1500) are also applicable in an analogous manner to method 900 described above with respect to FIGS. 9A-9C. For example, the user interfaces, display device, user interface elements and gaze location described above with reference to method 900 optionally have one or more of the characteristics of the user interfaces, display devices, user interface elements and gaze locations described herein with reference to other methods described herein (e.g., methods 700, 1100, 1300 and 1500). For brevity, these details are not repeated here.
The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in an information processing apparatus such as general purpose processors (e.g., as described above with respect to FIGS. 1A, 3 and 5) or application specific chips.
The operations described above with reference to FIGS. 9A-9C are, optionally, implemented by components depicted in FIGS. 1A-1B. For example, generation operation 902, determination operations 920 and 924, and performing operation 928 are, optionally implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B.
Audio-Based Presence Detection
Determining whether a person is present at a device can be beneficial in providing that person an enhanced user experience with the device. For example, if a television were able to determine that a person is in the presence of the television, the television could forgo going to sleep so the person's television-viewing can remain uninterrupted. The embodiments described below describe ways in which a device can determine whether a person is present at the device. A device that is able to determine whether a person is present at the device reduces the amount of interaction needed between the person and the device, and thus reduces the power usage of the device and increases battery life for battery-powered devices.
FIG. 10 illustrates exemplary ways in which a device optionally determines whether a person is present at the device in accordance with some embodiments of the disclosure. The embodiments in these figures are used to illustrate the processes described below, including the processes described with reference to FIGS. 11A-11B.
FIG. 10 illustrates an exemplary spatial configuration of devices according to embodiments of the disclosure. Device 1001 is optionally a device such as device 500 as described above with reference to FIG. 5, including a set top box or other user interface generating device that is in communication with a remote control and a display device. In the illustrated embodiment, device 1001 is coupled to sound-playback device 1002. Sound-playback device 1002 is optionally a speaker or any device having a speaker, such as a television. In the illustrated example, sound-playback device 1002 has speaker 1004. Sound-playback device 1002 optionally corresponds to one or more of multifunction device 100 in FIGS. 1A and 2, device 300 in FIG. 3, and display 514 in FIG. 5; speaker 1004 optionally corresponds to speaker 111 in FIGS. 1A and 2. Device 1008 is a sound-receiving device. Sound-receiving device 1008 is optionally a microphone or any device having a microphone, such as a mobile and/or wearable device. Sound-receiving device optionally corresponds to one or more of multifunction device 100 in FIGS. 1A and 2, microphone 113 in FIGS. 1A and 2, and device 300 in FIG. 3.
In some embodiments, device 1001 optionally determines whether sound-receiving device 1008 is present at sound-playback device 1002 by generating a first sound 1006 for playback on the sound-playback device. The first sound 1006 is optionally an audible sound, or an inaudible sound that is outside of the normal range of hearing for a human (e.g., below 20 Hz or above 20,000 Hz). While or after sound-playback device 1002 has played the first sound 1006, device 1001 optionally receives an output from the microphone on sound-receiving device 1008. Device 1001 optionally receives this output via a wireless connection with sound-receiving device 1008, such as via Bluetooth Low Energy (sometimes called Bluetooth LE).
Device 1001 then optionally determines whether sound-receiving device 1008 is present at sound-playback device 1002 based on a plurality of presence criteria. If the presence criteria are satisfied, device 1001 optionally designates a user of the sound-receiving device 1008 as being present at sound-playback device 1002. For example, when the presence criteria are satisfied with respect to a mobile phone, a user of the mobile phone is determined to be present at the sound-playback device. In some embodiments, only sound-receiving device 1008, and not a user of the sound-receiving device, is designated as being present when the presence criteria are satisfied. If the presence criteria are not satisfied with respect to the mobile phone, the user of the mobile phone is determined to be not present at the sound-playback device—this determination optionally encompasses simply not designating the user as present, or changing a “present” determination for that user to a “not present” determination.
In some embodiments, the presence criteria include sound-detection criteria that is satisfied when the output from the microphone on the sound-receiving device 1008 corresponds to the first sound 1006 for playback on sound-playback device 1002. For example, device 1001 optionally determines whether sound-receiving device 1008 detected the first sound 1006 played by the sound-playback device 1002 by comparing the first sound with the output from the microphone on the sound-receiving device. If the output from the microphone and the first sound 1006 match, then in some embodiments, the sound-detection criteria is satisfied.
In some embodiments, the presence criteria also include verification criteria that is satisfied when presence of the sound-receiving device 1008 at the sound-playback device 1002 is verified using something other than the first sound 1006. In other words, the verification criteria is optionally satisfied when device 1001 verifies that sound-receiving device 1008 is present at sound-playback device 1002 in a way other than through detection of first sound 1006. Some such verification methods optionally include facial recognition and/or sound-receiving device 1008 motion checks, as will be described in more detail below. Thus, in some embodiments, the user of the sound-receiving device 1008 is not designated as being present at sound-playback device 1002 until both the sound-detection criteria and the verification criteria are satisfied.
In some embodiments, designating the user of sound-receiving device 1008 as being present at sound-playback device 1002 includes determining a user associated with the sound-receiving device (e.g., determining who uses, owns, or is registered on the sound-receiving device), and designating that user as being present at the sound-playback device.
In some embodiments, prior to generating first sound 1006 for playback on sound-playback device 1002, device 1001 optionally transmits a wake command to sound-receiving device 1008 to request that the sound-receiving device turn on its microphone. For example, device 1001 optionally sends a wireless signal to a mobile device to have the mobile device turn on its microphone. In this way, sound-receiving device 1008 need not always keep its microphone on, preserving battery life.
In some embodiments, the verification criteria include a criterion that is satisfied when a face of the user of the sound-receiving device 1008 is recognized at the sound-playback device 1002. In such cases, device 1001 optionally ensures via facial recognition that the relevant user is at sound-playback device 1002 before designating that user as being present. In some embodiments, sound-playback device 1002 has a camera (such as an RGB, IR and/or depth camera) from which device 1001 optionally analyzes one or more images to check for facial recognition of the user.
In some embodiments, the verification criteria include a criterion that is satisfied when sound-receiving device 1008 has sensed motion during a most recent time period (e.g., a time period such as the last 1, 5, 15, or 30 minutes). In such cases, device 1001 optionally designates the user as being present at sound-playback device 1002 only if sound-playback device 1008 has recently sensed motion. Device 1001 does this so as to not designate a user as being present when that user has left, for example, their telephone in the room with sound-playback device 1002, and the user is not actually there.
In some embodiments, the verification criteria include a criterion that is satisfied when sound-receiving device 1008 is on the same wireless network (e.g., WiFi network or any wireless communication network) as the sound-playback device. In other words, in such embodiments, device 1001 checks to make sure that sound-playback device 1002 and sound-receiving device 1008 are on the same wireless network before designating the user as being present at the sound-playback device.
In some embodiments, the above presence determination is optionally re-performed when sound-receiving device 1008 has sensed a large amount of motion, to determine whether the large amount of motion corresponds to the user having left the room with the sound-receiving device while previously having been in the room, for example. In such embodiments, device 1001 optionally detects motion of sound-receiving device 1008. In accordance with a determination that the motion exceeds a predefined threshold (e.g., more than a predefined change in location, more than a predefined change in velocity, more than a predefined change in acceleration), the device optionally re-evaluates the plurality of presence criteria as described above to determine whether sound-receiving device 1008 remains at the sound-playback device 1002.
In some embodiments, sound-playback device 1002 is configured to go into, for example, a sleep state after a certain amount of time has passed without any activity being sensed at the sound-playback device. For example, a television is optionally configured to go to sleep after 30 minutes have passed without any input from a remote control or any video input to the television. In such cases, device 1001 optionally forgoes transitioning sound-playback device 1002 into the sleep state when the presence criteria are satisfied. For example, sound-playback device 1002 is optionally configured to transition from a first state (e.g., active or awake state, and optionally also includes a person's status on a chat program, for example) to a second state (e.g., inactive or sleep state, also optionally including a person's status on the chat program, for example) in response to one or more transition criteria (e.g., lack of activity in the user interface of the sound-playback device for longer than a threshold time period) being satisfied at the sound-playback device (e.g., transitioning a person's chat program status from “active” to “inactive” after a threshold time period of inactivity). However, in accordance with the determination that the plurality of presence criteria are satisfied, device 1001 optionally forgoes transitioning from the first state of the sound-playback device to the second state of the sound-playback device in response to the one or more transition criteria being satisfied at the sound-playback device. In other words, despite the one or more transition criteria being met, device 1001 optionally maintains the sound-playback device 1002 in the first (e.g., active or awake) state due to the determined presence of the person at the sound-playback device.
FIGS. 11A-11B are flow diagrams illustrating a method 1100 of performing presence detection in accordance with some embodiments (e.g., as described above with reference to FIG. 10). The method 1100 is performed at an electronic device such as device 500 as described above with reference to FIG. 5, including a set top box or other user interface generating device that is in communication with a remote control and a display device. Some operations in method 1100 are, optionally, combined and/or the order of some operations is, optionally, changed.
As described below, the method 1100 provides ways in which a device optionally determines the presence of a user without a user needing to manually designate his/her presence. The method reduces the cognitive burden on a user when interacting with the device, and reduces the need for the user to physically interact with the device, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, increasing the efficiency of the user's interaction with the device conserves power and increases the time between battery charges.
In some embodiments, an electronic device (e.g., a set top box or other user interface generating device that is in communication with a remote control and a display device, such as device 1001 in FIG. 10) with one or more processors and memory generates (1102) a first sound (e.g., an audible or inaudible sound that is outside of the normal range of hearing for a human (below 20 Hz or above 20,000 Hz), such as first sound 1006 in FIG. 10) for playback on a sound-playback device (e.g., a speaker or any device having a speaker, such as a television and/or device 1002 in FIG. 10). In some embodiments, the sound-playback device is configured to transition from a first state (e.g., active or awake state, and optionally also includes a person's status on a chat program, for example) to a second state (e.g., inactive or asleep state, also optionally including a person's status on the chat program, for example) in response to one or more transition criteria (e.g., lack of activity in the user interface for longer than a threshold time period) being satisfied at the sound-playback device (1104) (e.g., transitioning a person's chat program status from “active” to “inactive” after a threshold time period of inactivity).
In some embodiments, the device receives (1106) (e.g., via wireless communication, such as Bluetooth LE) an output from a microphone on a sound-receiving device (e.g., a microphone or any device having a microphone, such as a mobile and/or wearable device, sending data resulting from detecting the first sound to the electronic device; for example, device 1008 in FIG. 10). In some embodiments, prior to generating the first sound for playback on the sound-playback device, the device transmits a wake command to the sound-receiving device for turning on the microphone on the sound-receiving device (1108) (e.g., the device sends a wireless signal to a mobile device to have the mobile device turn on its microphone).
In some embodiments, the device determines (1110) whether the sound-receiving device is present at the sound-playback device based on a plurality of presence criteria, including sound-detection criteria that is satisfied when the output from the microphone on the sound-receiving device corresponds to the first sound for playback on the sound-playback device (1112) (e.g., the device determines whether the sound-receiving device detected the first sound played by the sound-playback device by comparing the first sound with the output from the microphone on the sound-receiving device), and verification criteria that is satisfied when a presence of the sound-receiving device at the sound-playback device is verified using a quantity other than the first sound (1114) (e.g., by facial recognition, motion checks, etc.). In some embodiments, the verification criteria include a criterion that is satisfied when a face of the user of the sound-receiving device is recognized at the sound-playback device (1116) (e.g., the device looks for a facial recognition match and a sound-based presence determination before designating the user as present). In some embodiments, the verification criteria include a criterion that is satisfied when the sound-receiving device has sensed motion during a most recent time period (1118) (e.g., a time period such as the last 1, 5, 15, or 30 minutes so as to ignore the sound-based presence determination if the mobile device has been left on a table in the room somewhere). In some embodiments, the verification criteria include a criterion that is satisfied when the sound-receiving device resides on a same wireless network as the sound-playback device (1120) (e.g., the device checks for sound-based presence and whether the sound-playback device and the sound-receiving device are on the same wireless network connection before designating the user as being present).
In accordance with a determination that the plurality of presence criteria are satisfied, in some embodiments, the device designates (1122) a user of the sound-receiving device as being present at the sound-playback device (e.g., when the presence criteria are satisfied with respect to a mobile phone, a user of the mobile phone is determined to be present at the sound-playback device. If the presence criteria are not satisfied with respect to the mobile phone, the user of the mobile phone is determined to be not present at the sound-playback device—this determination optionally encompasses simply not designating the user as present, or changing a “present” determination for that user to a “not present” determination). In some embodiments, designating the user of the sound-receiving device as being present at the sound-playback device comprises determining a user associated with the sound-receiving device (e.g., determining who uses, owns, or is registered on the sound-receiving device), and designating the user as being present at the sound-playback device (1124). In some embodiments, in accordance with the determination that the plurality of presence criteria are satisfied, the device forgoes (1126) transitioning from the first state of the sound-playback device to the second state of the sound-playback device in response to the one or more transition criteria being satisfied at the sound-playback device (e.g., despite the one or more transition criteria being met, maintaining the sound-playback device in the first (e.g., active or awake) state due to the presence of the person in front of the display device).
In some embodiments, the device detects (1130) motion of the sound-receiving device. In some embodiments, in accordance with a determination that the motion exceeds a predefined threshold (e.g., more than a predefined change in location, more than a predefined change in velocity, more than a predefined change in acceleration), the device re-evaluates (1132) the plurality of presence criteria to determine whether the sound-receiving device remains at the sound-playback device (e.g., the device determines whether a user has left the room while previously having been in the room).
It should be understood that the particular order in which the operations in FIGS. 11A-11B have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 700, 900, 1300 and 1500) are also applicable in an analogous manner to method 1100 described above with respect to FIGS. 11A-11B. For brevity, these details are not repeated here.
The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in an information processing apparatus such as general purpose processors (e.g., as described above with respect to FIGS. 1A, 3 and 5) or application specific chips.
The operations described above with reference to FIGS. 11A-11B are, optionally, implemented by components depicted in FIGS. 1A-1B. For example, generation operation 1102, receiving operation 1106, determination operation 1110 and designation operation 1122 are, optionally implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B.
Distance Determination
Displaying different user interfaces on a device based on whether a person is far away from the device or close to the device can enhance the person's interaction with the device. For example, a television can present a user interface with large user interface elements that provide summary information (e.g., information about the current program and the next program) when a person is far away from the television, and can present more detailed information (e.g., a program guide with information about programs from multiple channels and multiple time slots) when the person is close to the television. The embodiments described below describe ways in which a person's interaction with a device can be enhanced by providing different user interfaces at different distances. Enhancing a person's interactions with a device reduces the amount of time needed by the person to perform operations, and thus reduces the power usage of the device and increases battery life for battery-powered devices.
FIGS. 12A-12B illustrate exemplary ways in which different user interfaces are optionally presented at different distances in accordance with some embodiments of the disclosure. The embodiments in these figures are used to illustrate the processes described below, including the processes described with reference to FIGS. 13A-13D.
FIG. 12A illustrates an exemplary user interface 1200 for display on display device 1002 when person 1210 is far from the display device. Display device 1002 is optionally any display device, such as a television or other display device. Display device 1002 is optionally coupled to device 1001, which is optionally a device such as device 500 as described above with reference to FIG. 5, including a set top box or other user interface generating device that is in communication with a remote control and a display device.
In some embodiments, device 1001 determines whether person 1210 is further than threshold distance 1208 from display device 1002, or closer than the threshold distance from the display device. Device 1001 optionally makes this distance determination based on information received from one or more optical sensors, such as IR, depth and/or RGB cameras. In the illustrated embodiment, person 1210 is further than threshold distance 1208 from display device 1002. Threshold distance 1208 is optionally any number of distances, fixed or variable, such as 1/10, 1⁄2, 1, 3, or 5 meters from display device 1002.
If, as illustrated in FIG. 12A, device 1001 determines that person 1210 is further than threshold distance 1208 from display device 1002, the device optionally provides user interface 1200 for display on the display device. User interface 1200 is optionally any user interface suited for or intended for presentation when person 1210 is further than threshold distance 1208 from display device 1002. For example, user interface 1200 is optionally a user interface including summary information, a screen saver, application windows without relatively small user interface elements, user interface elements at a relatively large size, and/or status information (e.g., date, time, weather, news headlines, stock prices, number of unread emails, etc.). In the illustrated embodiment, user interface 1200 includes two user interface elements 1202 and 1204. User interface element 1202 is optionally a content item, such as a video or an image. User interface element 1204 is optionally an information bar, providing information about the content item (e.g., user interface element 1202), such as a title and a description.
FIG. 12B illustrates an exemplary user interface 1201 for display on display device 1002 when person 1210 is close to the display device. In the illustrated embodiment, device 1001 has determined that person 1210 is closer than threshold distance 1208 from display device 1002. Thus, device 1001 optionally provides user interface 1201 for display on display device 1002. User interface 1201 is optionally any user interface suited for or intended for presentation when person 1210 is closer than threshold distance 1208 from display device 1002. For example, user interface 1201 is optionally a user interface including detailed information, a home screen, application windows including relatively small user interface elements, and/or user interface elements at a relatively small size. In the illustrated embodiment, user interface includes three user interface elements 1202, 1204, and 1206. User interface elements 1202 and 1204 are optionally smaller versions of the same user interface elements that were in user interface 1200 (e.g., the user interface that is displayed when the person is far away from the display device). User interface element 1206 is optionally a user interface element that is not included in user interface 1200 (e.g., the user interface that is displayed when the person is far away from the display device), and is only included in user interface 1201. For example, user interface element 1206 is optionally a channel or application bar from which various content (such as media content or applications) is optionally accessed. User interface element 1206 is optionally only included in user interface 1201 because it is optionally better suited for close viewing/interaction as opposed to far viewing/interaction.
As described above, device 1001 optionally provides a different user interface for display on display device 1002 depending on whether person 1210 is further than or closer than threshold distance 1208 from display device 1002.
In some embodiments, the device optionally identifies a face of the person based on the information received from the one or more optical sensors. In such implementations, the determination as to whether the person is further than the threshold distance from the display device or closer than the threshold distance from the display device is optionally based on the size of the face of the person (e.g., by comparing the size of face to a “standard” sized face known to be at a reference distance, and extrapolating the person's distance based on the comparison).
In some embodiments, the device optionally detects movement of the person from a distance further than the threshold distance to a distance closer than the threshold distance from the display device. In response to detecting the movement, the device optionally provides the “close” user interface (e.g., the user interface that is displayed when the person is near to the display device) for display on the display device.
In some embodiments, the device optionally detects movement of the person from a distance closer than the threshold distance to a distance further than the threshold distance from the display device. In response to detecting the movement, the device optionally provides the “far” user interface (e.g., the user interface that is displayed when the person is far from the display device) for display on the display device.
In some embodiments, the person is further than the threshold distance from the display device, and the “far” user interface is provided for display on the display device. The “far” user interface optionally includes a first user interface element (e.g., an email graphic) and a second user interface element (e.g., a music collection graphic). While the “far” user interface is displayed on the display device, the device optionally determines a gaze location in the “far” user interface, where the gaze location is a location in the “far” user interface to which the person looking. The device optionally detects movement of the person to a distance closer than the threshold distance from the display device (e.g., the person is moving towards the display device). In response to detecting the movement of the person, the device provides the “close” user interface (e.g., the user interface that is displayed when the person is near the display device) for display on the display device, where the “close” user interface includes information based on the gaze location. For example, when a person is looking at an email, when the person moves closer to the display, additional details about the email are optionally displayed (e.g., a sender, other recipients, timestamps, etc.). As another example, if the person is looking at an image of cover art for a music album, when the person moves closer to the display, additional details about the album are displayed (e.g., a track list, artist, track times, etc.). Optionally, when the additional information is displayed based on the gaze location, additional information is not displayed for other user interface elements that the person is not looking at (e.g., when cover art for multiple albums is displayed, a track list is only displayed for the album corresponding to the cover art that the person is looking at when the person gets closer to the display and is not displayed for other albums).
In some embodiments, the device logs the person out of any areas the person might be logged into when the person moves away from the display device. For example, the person might be close to the display device, and logged into one or more areas on the device (e.g., iTunes store, email service, etc.). The device optionally detects movement of the person to a distance further than the threshold distance from the display device (e.g., the person is moving away from the display device), and in response, optionally logs out of the one or more areas on the electronic device. For example, the device optionally logs out of the person's iTunes store account when that person leaves the display device.
In some embodiments, the “far” and “close” user interfaces include the same user interface element at different sizes. For example, the “far” user interface optionally includes a user interface element (e.g., text string, application window, button, etc.) at a first size. The “close” user interface optionally includes the same user interface element at a second size, smaller than the first size.
In some embodiments, the “far” user interface provides summary information about something, and the “close” user interface provides detailed information about that same thing. For example, the “far” user interface optionally includes summary information about a first quantity (e.g., weather, unread emails, etc.), and the “close” user interface optionally includes detailed information about the first quantity. Thus, in some embodiments, the “far” user interface optionally includes a snapshot of the weather, such as a high temperature, low temperature, and current temperature for the current day, and the “close” user interface optionally includes more detailed information about the weather, such as the above temperatures as well as the humidity, chance of rain, wind, and wind chill for the current day.
In some embodiments, the “far” user interface does not include one or more user interface elements that are optionally included in the “close” user interface. For example, the “close” user interface optionally includes application windows, a menu bar and an application dock. Because the menu bar and application bar could be difficult to view and/or interact with at a distance, the “far” user interface optionally includes only the application windows, and not the menu bar or the application dock.
FIGS. 13A-13D are flow diagrams illustrating a method 1300 of providing different user interfaces at different distances in accordance with some embodiments (e.g., as described above with reference to FIGS. 12A-12B). The method 1300 is performed at an electronic device such as device 500 as described above with reference to FIG. 5, including a set top box or other user interface generating device that is in communication with a remote control and a display device. Some operations in method 1300 are, optionally, combined and/or the order of some operations is, optionally, changed.
As described below, the method 1300 provides ways in which a device optionally provides different user interfaces based on the distance of a user from a display device. The method reduces the cognitive burden on a user when interacting with a user interface on the device, and reduces the need for the user to physically interact with the device, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, increasing the efficiency of the user's interaction with the user interface conserves power and increases the time between battery charges.
In some embodiments, an electronic device (e.g., a set top box or other user interface generating device that is in communication with a remote control and a display device, such as device 1001 in FIG. 12A) with one or more processors and memory determines (1302) whether a person (e.g., person 1210 in FIG. 12A) is further than a threshold distance (e.g., further than a distance such as 1/10, 1⁄2, 1, 3 or 5 meters, such as distance 1208 in FIG. 12A) from a display device (e.g., a television or other display device, such as device 1002 in FIG. 12A) or closer than the threshold distance from the display device. In some embodiments, determining whether the person is further than the threshold distance from the display device or closer than the threshold distance from the display device is based on information received from one or more optical sensors (1304) (e.g., IR, depth, and/or RGB cameras).
In accordance with a determination that the person is further than the threshold distance from the display device, in some embodiments, the device provides (1306) a first user interface (e.g., a user interface including summary information, a screen saver, application windows without small user interface elements, user interface elements at a larger size, status information (e.g., date, time, weather, news headlines, stock prices, number of unread emails), such as user interface 1200 in FIG. 12A) for display on the display device. In some embodiments, the first user interface (e.g., the user interface that is displayed when the user is far away from the display device) includes a user interface element (e.g., text string, application window, button, etc.) at a first size (1308) (e.g., user interface element 1202 in FIG. 12A). In some embodiments, the first user interface includes summary information about a first quantity (1310) (e.g., weather, unread emails, etc.). In some embodiments, the first user interface includes a first set of user interface elements (1312) (e.g., application windows, such as user interface elements 1202 and 1204 in FIG. 12A).
In accordance with a determination that the person is closer than the threshold distance from the display device, in some embodiments, the device provides (1314) a second user interface (e.g., a user interface including detailed information, a home screen, application windows including small user interface elements, user interface elements at a smaller size, such as user interface 1201 in FIG. 12B) for display on the display device. In some embodiments, the second user interface is different than the first user interface (1316). In some embodiments, the second user interface (e.g., the user interface that is displayed when the user is near to the display device) includes the user interface element (e.g., text string, application window, button, etc.) at a second size, smaller than the first size (1318) (e.g., user interface element 1202 in FIG. 12B). In some embodiments, the second user interface includes detailed information about the first quantity (1320) (e.g., the first user interface includes a snapshot of the weather, such as a high temperature, low temperature, and current temperature for the current day, and the second user interface includes more detailed information about the weather, such as the above temperatures as well as the humidity, chance of rain, wind, and wind chill for the current day). In some embodiments, the second user interface includes the first set of user interface elements (e.g., the application windows that were displayed when the user was far away from the device, such as user interface elements 1202 and 1204 in FIGS. 12A and 12B) and a second set of user interface elements (1322) (e.g., a relatively small menu bar and dock, such as user interface element 1206 in FIG. 12B, and the application windows that were displayed when the user was far away from the device).
In some embodiments, the device identifies (1324) a face of the person based on the information received from the one or more optical sensors. In some embodiments, determining whether the person is further than the threshold distance from the display device or closer than the threshold distance from the display device is based on a size of the face of the person (1326) (e.g., the device compares the size of the face to a “standard” sized face known to be at a reference distance, and extrapolates the person's distance based on the comparison).
In some embodiments, the person is determined to be further than the threshold distance (e.g., further than a distance such as 1/10, 1⁄2, 1, 3 or 5 meters) from the display device (1328). In some embodiments, while the first user interface (e.g., the user interface that is displayed when the user is far away from the display device) is displayed on the display device, the device detects (1330) movement of the person to a distance closer than the threshold distance from the display device. In some embodiments, in response to detecting the movement of the person to the distance closer than the threshold distance, the device provides (1332) the second user interface (e.g., the user interface that is displayed when the user is near to the display device) for display on the display device.
In some embodiments, the person is determined to be closer than the threshold distance (e.g., closer than a distance such as 1/10, 1⁄2, 1, 3 or 5 meters) from the display device (1334). In some embodiments, while the second user interface (e.g., the user interface that is displayed when the user is near to the display device) is displayed on the display device, the device detects (1336) movement of the person to a distance further than the threshold distance from the display device. In some embodiments, in response to detecting the movement of the person to the distance further than the threshold distance, the device provides (1338) the first user interface (e.g., the user interface that is displayed when the user is far away from the display device) for display on the display device.
In some embodiments, the person is further than the threshold distance (e.g., further than a distance such as 1/10, 1⁄2, 1, 3 or 5 meters) from the display device, and the first user interface (e.g., the user interface that is displayed when the user is far away from the display device) is provided for display on the displace display device, the first user interface including a first user interface element (e.g., an email graphic) and a second user interface element (1340) (e.g., a music collection graphic). In some embodiments, while the first user interface is displayed on the display (1342) the device determines (1344) a gaze location in the first user interface, wherein the gaze location comprises a location in the first user interface to which the person's gaze is directed, and detects (1346) movement of the person to a distance closer than the threshold distance from the display device (e.g., the person is moving towards the display device). In some embodiments, in response to detecting the movement of the person, the device provides (1348) the second user interface (e.g., the user interface that is displayed when the user is near to the display device) for display on the display device, the second user interface including information based on the gaze location (e.g., based on where in the user interface the person is looking). For example, when a person is looking at an email, when the person moves closer to the display, additional details about the email are displayed (e.g., a sender, other recipients, timestamps, etc.). As another example, if the person is looking at an image of cover art for a music album, when the person moves closer to the display, additional details about the album are displayed (e.g., a track list, artist, track times, etc.). Optionally, when the additional information is displayed based on the gaze location, additional information is not displayed for other user interface elements that the person is not looking at (e.g., when cover art for multiple albums is displayed, a track list is only displayed for the album corresponding to the cover art that the person is looking at when the person gets closer to the display and is not displayed for other albums).
In some embodiments, the device determines (1350) whether the gaze location coincides with the first user interface element or the second user interface element in the first user interface (e.g., the device determines whether the person is looking at the email graphic or the music collection graphic). In some embodiments, in response to detecting the movement of the person to the distance closer than the threshold distance from the display device (1352) (e.g., the person is moving towards the display device), in accordance with a determination that the gaze location coincides with the first user interface element (e.g., the person is looking at the email graphic), the device provides (1354) the second user interface (e.g., the user interface that is displayed when the user is near to the display device) for display on the display device, the second user interface including information associated with the first user interface element (e.g., more information about the person's emails, such as email previews, names of senders of unread emails, etc.), and in accordance with a determination that the gaze location coincides with the second user interface element (e.g., the person is looking at the music collection graphic), the device provides (1356) the second user interface (e.g., the user interface that is displayed when the user is near to the display device) for display on the display device, the second user interface including information associated with the second user interface element (e.g., more information about the person's music collection, such as new songs, artists of new songs, etc.).
In some embodiments, the person is closer than the threshold distance from the display device, and the person is logged into one or more areas (e.g., iTunes store, email service, etc.) on the electronic device (1358). In some embodiments, the device detects (1360) movement of the person to a distance further than the threshold distance from the display device (e.g., the person is moving away from the display device). In some embodiments, in response to detecting the movement of the person to the distance further than the threshold distance from the display device, the device logs out (1362) of the one or more areas on the electronic device (e.g., the device logs out of the person's iTunes store account when they leave the display device).
It should be understood that the particular order in which the operations in FIGS. 13A-13D have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 700, 900, 1100 and 1500) are also applicable in an analogous manner to method 1300 described above with respect to FIGS. 13A-13D. For example, the user interfaces, display device, user interface elements, gaze locations and optical sensors described above with reference to method 1300 optionally have one or more of the characteristics of the user interfaces, display devices, user interface elements, gaze locations and optical sensors described herein with reference to other methods described herein (e.g., methods 700, 900, 1100 and 1500). For brevity, these details are not repeated here.
The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in an information processing apparatus such as general purpose processors (e.g., as described above with respect to FIGS. 1A, 3 and 5) or application specific chips.
The operations described above with reference to FIGS. 13A-13D are, optionally, implemented by components depicted in FIGS. 1A-1B. For example, determination operation 1302, and providing operations 1306 and 1314 are, optionally implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B.
Presence Determination
Performing various actions at a device based on whether a person is present at the device can be beneficial in providing that person an enhanced user experience with the device. For example, if a television were able to determine whether a person is in the presence of the television, the television could take certain actions that can enhance the person's experience with the device. The embodiments described below describe ways in which a device can enhance a person's experience with the device based on whether the person is present at the device. Enhancing a person's experience with a device reduces the amount of time needed by the person to perform operations, and thus reduces the power usage of the device and increases battery life for battery-powered devices.
FIGS. 14A-14B illustrate exemplary ways in which a person's experience with a device is optionally enhanced based on presence detection in accordance with some embodiments of the disclosure. The embodiments in these figures are used to illustrate the processes described below, including the processes described with reference to FIGS. 15A-15C.
FIG. 14A illustrates an exemplary user interface 1400 in accordance with embodiments of the disclosure. In the illustrated embodiment, user interface 1400 includes a video of a ball 1402 moving across the screen. In some embodiments, user interface 1400 includes the playing of any media content, such as a movie or music. User interface is optionally for display on display device 1002, which is optionally any type of display device, such as a television. Display device 1002 is optionally coupled to device 1001. Device 1001 is optionally a device such as device 500 as described above with reference to FIG. 5, including a set top box or other user interface generating device that is in communication with a remote control and a display device.
In some embodiments, while the media content is playing in user interface 1400, device 1001 optionally determines whether one or more presence criteria are satisfied. These presence criteria optionally include a criterion that is satisfied while a person is present at display device 1002. In other words, device 1001 optionally determines whether a person is present at display device 1002. If device 1001 determines that a person is present at display device 1002, the device optionally maintains the playing of the media content in user interface 1400, as illustrated. More generally, in some embodiments, if device 1001 determines that the one or more presence criteria are satisfied, the device optionally maintains the playing of the media content in user interface 1400. Whether the one or more presence criteria are satisfied is optionally determined based on information received from one or more optical sensors (e.g., IR, depth, and/or RGB cameras).
FIG. 14B illustrates user interface 1400 when device 1001 determines that the one or more presence criteria are not satisfied. In the illustrated embodiment, device 1001 has determined that a person is not (or no longer) present at display device 1002. As a result, device 1001 optionally modifies the playing of the media content in a first manner. In the illustrated embodiment, device 1001 has paused the playing of the video of the ball 1402 moving across the screen. In some embodiments, in accordance with a determination that the one or more presence criteria are not satisfied, device 1001 pauses the media content (as illustrated), bookmarks a current position in the media content, reduces a volume of the media content, or performs any other modification of the playing of the media content. As such, modification of the playing of media content is based on whether one or more presence criteria are satisfied.
In some embodiments, the device optionally transfers the playing of the media content to another device when the one or more presence criteria are not satisfied. For example, in accordance with a determination that the one or more presence criteria are not satisfied, the device optionally determines a second device (e.g., mobile device) associated with a first person (e.g., the first person's iPhone). Then, the device optionally transfers the playing of the media content to the second device. For example, the device optionally transfers the playing of the media content from the display device to the first person's iPhone in response to determining that the first person is no longer present at the display device. This transfer is optionally accomplished, for example, by transferring an indication of progress of the first person in the media content so that the media content will start playing on the second device where the user left off on the first device. In some embodiments, transferring the playing of the media content includes initiating playback of the media content on the second device. In some embodiments, transferring the playing of the media content includes transferring the media content from the first device to the second device. In some embodiments, the playing of the media content is transferred to the second device without transferring the media content to the second device (e.g., because the content is already present on both devices or because both devices are streaming the content from a remote source such as a video or audio streaming service).
In some embodiments, the device modifies the playing of the media content even if the one or more presence criteria are satisfied. For example, in some embodiments, in accordance with a determination that the one or more presence criteria are satisfied (e.g., the first person is present at the display device), the device optionally determines a relative location of the first person with respect to the display device. In other words, the device optionally determines where in relation to the display device the first person is. Then, the device optionally modifies the playing of the media content in a second manner (e.g., by beamforming the audio of the media content), different from the first manner, based on the relative location of the first person. Thus, in some embodiments, the device optionally adjusts the audio output of the media content to beamform the audio to the first person's position.
In some embodiments, in accordance with a determination that the one or more presence criteria are satisfied (e.g., the first person is present at the display device), the device optionally determines a distance of the first person from the display device, and modifies the playing of the media content in a second manner, different from the first manner, based on the distance of the first person from the display device. For example, in some embodiments, the device adjusts the volume of the media content or the size of the media content in the display based on the distance of the first person from the display device (e.g., if the first person is far from the display device, the device optionally increased the volume of the media content).
In some embodiments, the one or more presence criteria include a criterion that is satisfied when the first person is oriented towards the display device (e.g., the first person's face, shoulders, and/or torso are positioned towards the display device). In some embodiments, the one or more presence criteria include a criterion that is satisfied when the first person's gaze is directed at the display device (e.g., the first person is looking at the display device). In other words, in these embodiments, the device does not count the first person as being “present” unless the first person is oriented towards the display device and/or the first person is looking at the display device. If these criteria are not met, the device optionally determines that the first person is not paying attention to the playing of the media content in the user interface, and modifies the playing of the media content, as described above and/or below.
In some embodiments, the device reacts accordingly when two or more people are present at the display device. For example, while displaying the media content to a single person (e.g., after detecting that the presence criteria are met for the first person), the device optionally detects that two or more people are present at the display device (e.g., detecting that the presence criteria are met for a first person and a second person). In accordance with a determination that two or more people are present at the display device, the device optionally modifies the playing of the media content in a second manner by increasing a visibility (e.g., size, brightness, and placement) of the media content in the user interface. For example, the device optionally enlarges the media content in the user interface to facilitate easier viewing by two or more people concurrently, as each of the two or more people will, in some circumstances, need to be further from the display device than if there were only a single person watching.
In some circumstances, some or all of the media content is designated as private media content, and thus the device is configured to respond accordingly when two or more people are present at the display device. For example, while displaying the media content to a single person (e.g., after detecting that the presence criteria are met for the first person), the device optionally detects that two or more people are present at the display device. In accordance with a determination that two or more people are present at the display device, the device optionally determines whether the media content is designated as private media content (e.g., not to be shared with more than the person associated with it). In accordance with a determination that the media content is designated as private media content, the device optionally modifies the playing of the media content in a second manner by reducing a visibility of the media content (e.g., hiding, fading out, turning off the display device) in the user interface. Thus, the device optionally hinders the viewing of private media content by others.
In some embodiments, in accordance with a determination that the media content is not designated as private media content (e.g., the media content can be shared with more than the person associated with it), the device optionally modifies the playing of the media content in a third manner by increasing the visibility (e.g., size, brightness, placement) of the media content in the user interface (e.g., enlarging the media content in the user interface to facilitate easier viewing by two or more people concurrently, as each of the two or more people will, in some circumstances, need to be further from the display device than if there were only a single person watching).
In some embodiments, when the one or more presence criteria are satisfied, an action is optionally performed on the device based on activity being performed on a second device. For example, in accordance with a determination that the one or more presence criteria are satisfied (e.g., the first person is present at the display device), the device optionally determines whether a second device (e.g., mobile device) is present at the display device with the first person, and whether a specified type of activity (e.g., activities better suited for the display device rather than the mobile device) is being performed on the second device (e.g., mobile device). If so, in accordance with a determination that the second device is present at the display device with the first person and that the specified type of activity is being performed on the second device, the device (the “first device”) optionally performs an action on the first device (e.g., a set top box or other user interface generating device that is in communication with a remote control and a display device) based on the activity being performed on the second device.
For example, the first device optionally transfers activity (e.g., playback of media content, video chatting) from the mobile device to the first device (e.g., set top box), and/or provides mobile device status information (e.g., incoming phone call, new email notification, etc.) on the display device (e.g., television). For example, if the first person is engaged in a video chat on a mobile device, when the first person and the mobile device are present at the display device, the first device optionally transfers the video chat from the mobile device to the first device so that the first person can continue the video chat on the display device, which could be a device such as a television. Such a transfer is also optionally performed for playback of media content (e.g., a movie) on the mobile device; specifically, transferring playback of the media content from the mobile device to the first device for display on the display device. As another example, status information about events on a mobile device are optionally provided on the display device when the first person and the mobile device are determined to be present at the display device such that the first person can easily see this information without having to look at the mobile device—status information such as information about incoming phone calls (e.g., caller name and number), new email messages received (e.g., sender name, subject line, first few lines of the email), new text messages received (e.g., sender name, first few lines of the text message), etc.
In some embodiments, the device reverts playback of the media content to its original playback mode when the person returns to the display device. For example, in some embodiments, at a first point in time, the one or more presence criteria are not satisfied (e.g., the person is not present at the display device), and the playing of the media content is modified in the first manner (e.g., pausing the media content, bookmarking a current position in the media content, reducing a volume of the media content). At a second point in time, after the modification of the playing of the media content in the first manner, in some embodiments, the device determines that the one or more presence criteria are satisfied (e.g., the person returns to the display device). In response to determining that the one or more presence criteria are satisfied, the device optionally reverses the modification of the playing of the media content in the first manner (e.g., resuming playback of the media content, increasing the volume of the media content, etc.).
FIGS. 15A-15C are flow diagrams illustrating a method 1500 of modifying media content playback based on presence detection in accordance with some embodiments (e.g., as described above with reference to FIGS. 14A-14B). The method 1500 is performed at an electronic device such as device 500 as described above with reference to FIG. 5, including a set top box or other user interface generating device that is in communication with a remote control and a display device. Some operations in method 1500 are, optionally, combined and/or the order of some operations is, optionally, changed.
As described below, the method 1500 provides ways in which a device optionally modifies the playback of media content in a user interface based on presence detection. The method reduces the cognitive burden on a user when interacting with a user interface on the device, and reduces the need for the user to physically interact with the device, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, increasing the efficiency of the user's interaction with the user interface conserves power and increases the time between battery charges.
In some embodiments, an electronic device (e.g., a set top box or other user interface generating device that is in communication with a remote control and a display device, such as device 1001 in FIG. 14A) with one or more processors and memory (the “first device”) plays (1502) media content (e.g., movie or music, such as the video presented in user interface 1400 in FIG. 14A) on the first device. In some embodiments, the media content is included in a user interface (such as user interface 1400 in FIG. 14A) for display on a display device (1504) (such as display 1002 in FIG. 14A). In some embodiments, the first device determines (1506) whether one or more presence criteria are satisfied. In some embodiments, the one or more presence criteria include a criterion that is satisfied while a first person is present at the display device (1508). In some embodiments, the one or more presence criteria include a criterion that is satisfied when the first person is oriented towards the display device (1510) (e.g., the first person's face, shoulders, and/or torso are positioned towards the display device). In some embodiments, the one or more presence criteria include a criterion that is satisfied when the first person's gaze is directed at the display device (1512) (e.g., the first person is looking at the display device). In some embodiments, determining whether the one or more presence criteria are satisfied is based on information received from one or more optical sensors (1514) (e.g., IR, depth, and/or RGB cameras).
In accordance with a determination that the one or more presence criteria are not satisfied, in some embodiments, the first device modifies (1516) the playing of the media content in a first manner (e.g., pausing the media content, bookmarking a current position in the media content, reducing a volume of the media content, such as is illustrated in FIG. 14B). In some embodiments, the first device determines (1518) a second device (e.g., mobile device) associated with the first person (e.g., the first person's iPhone). In some embodiments, modifying the playing of the media content in the first manner comprises transferring the playing of the media content to the second device (1520) (e.g., transferring the playing of the media content from the display device to the first person's iPhone in response to determining that the first person is no longer present at the display device, for example by transferring an indication of progress of the user in the content so that the content will start playing on the second device where the user left off on the first device). In some embodiments, transferring the playing of the media content includes initiating playback of the content on the second device. In some embodiments, transferring the playing of the media content includes transferring the media content from the first device to the second device. In some embodiments, the playing of the media content is transferred to the second device without transferring the media content to the second device (e.g., because the content is already present on both devices or because both devices are streaming the content from a remote source such as a video or audio streaming service).
In some embodiments, in accordance with a determination that the one or more presence criteria are satisfied (e.g., the first person is present at the display device), the first device maintains (1524) the playing of the media content in the user interface (e.g., the first device continues playing the media content when the first person is present at the display device). In some embodiments, the first device determines (1526) a relative location of the first person with respect to the display device (e.g., where in relation to the display device the first person is present). In some embodiments, the first device modifies (1528) the playing of the media content in a second manner (e.g., beamforming audio associated with the media content) based on the relative location of the first person (e.g., the first device adjusts the audio output of the media content to beamform the audio to the first person's position), wherein the second manner is different from the first manner. In some embodiments, the first device determines (1530) a distance of the first person from the display device. In some embodiments, the first device modifies (1532) the playing of the media content in a second manner (e.g., beamforming audio, adjusting volume, adjusting the size of media content displayed) based on the distance of the first person from the display device, wherein the second manner is different from the first manner. In some embodiments, the first device determines (1534) whether a second device (e.g., mobile device) is present at the display device with the first person, and whether a specified type of activity (e.g., activities better suited for the display device rather than the mobile device) is being performed on the second device. In some embodiments, in accordance with a determination that the second device is present at the display device with the first person and that the specified type of activity is being performed on the second device, the first device (e.g., a set top box or other user interface generating device that is in communication with a remote control and a display device) performs (1536) an action on the first device based on the activity being performed on the second device (e.g., the first device transfers an activity (e.g., playback of media content, video chatting) from the mobile device to the first device (e.g., set top box), provides mobile device status information (e.g., incoming phone calls, new email notifications, etc.) on the display device (e.g., television), etc.). For example, if the first person is engaged in a video chat on a mobile device, when the first person and the mobile device are present at the display device, the first device transfers the video chat from the mobile device to the first device so that the first person can continue the video chat on the display device, which could be a device such as a television. Such a transfer is also optionally performed for playback of media content (e.g., a movie) on the mobile device; specifically, transferring playback of the media content from the mobile device to the first device for display on the display device. As another example, status information about events on a mobile device is optionally provided on the display device when the first person and the mobile device are determined to be present at the display device such that the first person can easily see this information without having to look at the mobile device—status information is optionally information such as information about incoming phone calls (e.g., caller name and number), new email messages received (e.g., sender name, subject line, first few lines of the email), new text messages received (e.g., sender name, first few lines of the text message), etc.
In some embodiments, while displaying the media content to a single person (1538) (e.g., after detecting that the presence criteria are met for the first person), the first device detects (1540) that two or more people are present at the display device (e.g., detecting that the presence criteria are met for a first person and a second person). In some embodiments, in accordance with a determination that two or more people are present at the display device (1542), the first device modifies (1544) the playing of the media content in a second manner by increasing a visibility (e.g., size, brightness, placement) of the media content in the user interface (e.g., enlarging the media content in the user interface to facilitate easier viewing by two or more people concurrently, as each of the two or more people will optionally need to be further from the display device than if there were only a single person watching). In some embodiments, the first device determines (1546) whether the media content is designated as private media content (e.g., not to be shared with more than the person associated with it). In some embodiments, in accordance with a determination that the media content is designated as private media content, the first device modifies (1548) the playing of the media content in a second manner by reducing a visibility of the media content (e.g., hiding, fading out, turning off the display device) in the user interface. In some embodiments, in accordance with a determination that the media content is not designated as private media content (e.g., the media content can be shared with more than the person associated with it), the first device modifies (1550) the playing of the media content in a third manner by increasing the visibility (e.g., size, brightness, placement) of the media content in the user interface (e.g., enlarging the media content in the user interface to facilitate easier viewing by two or more people concurrently, as each of the two or more people will optionally need to be further from the display device than if there were only a single person watching).
In some embodiments, at a first point in time, the one or more presence criteria are not satisfied (e.g., the person is not present at the display device), and the playing of the media content is modified in the first manner (1552) (e.g., pausing the media content, bookmarking a current position in the media content, reducing a volume of the media content). In some embodiments, at a second point in time, after the modification of the playing of the media content in the first manner, the first device determines (1554) that the one or more presence criteria are satisfied (e.g., the person returns to the display device). In some embodiments, in response to determining that the one or more presence criteria are satisfied, the first device reverses (1556) the modification of the playing of the media content in the first manner (e.g., resuming playback of the media content, increasing the volume of the media content, etc.).
It should be understood that the particular order in which the operations in FIGS. 15A-15C have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 700, 900, 1100 and 1300) are also applicable in an analogous manner to method 1500 described above with respect to FIGS. 15A-15C. For example, the user interfaces, display device, media content and optical sensors described above with reference to method 1500 optionally have one or more of the characteristics of the user interfaces, display devices, media content (or content items) and optical sensors described herein with reference to other methods described herein (e.g., methods 700, 900, 1100 and 1300). For brevity, these details are not repeated here.
The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in an information processing apparatus such as general purpose processors (e.g., as described above with respect to FIGS. 1A, 3 and 5) or application specific chips.
The operations described above with reference to FIGS. 15A-15C are, optionally, implemented by components depicted in FIGS. 1A-1B. For example, playing operation 1502, determination operation 1506, and modification operation 1516 are, optionally implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B.
In accordance with some embodiments, FIG. 16 shows a functional block diagram of an electronic device 1600 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in FIG. 16 are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.
As shown in FIG. 16, an electronic device 1600 optionally includes a receiving unit 1602 configured to receive images, sensor units 1614 configured to sense an orientation of the electronic device, and a processing unit 1604 coupled to the receiving unit 1602 and the sensor units 1614. In some embodiments, the processing unit 1604 includes a display enabling unit 1606, an identifying unit 1608, a performing unit 1610 and a determining unit 1612.
In some embodiments, the receiving unit 1602 is configured to receive a first image including a face of a first person. In some embodiments, the processing unit 1604 is configured to generate a user interface for display on a display device (e.g., with the display enabling unit 1606), identify the face of the first person from the first image (e.g., with the identifying unit 1608), and perform an action on the electronic device in accordance with the identification of the face of the first person (e.g., with the performing unit 1610).
In some embodiments, the user interface includes a second image that includes a face of a second person, the face of the second person being different from the face of the first person, and the processing unit 1604 is further configured to identify the face of the second person from the second image (e.g., with the identifying unit 1608), wherein performing the action on the electronic device in accordance with the identification of the face of the first person comprises replacing the face of the second person in the second image with the face of the first person in the first image (e.g., with the performing unit 1610). In some embodiments, the processing unit 1604 is further configured to determine an orientation of the face of the first person in the first image with respect to the display device (e.g., with the determining unit 1612), wherein performing the action on the electronic device in accordance with the identification of the face of the first person comprises aligning the user interface for display on the display device with the orientation of the face of the first person in the first image (e.g., with the performing unit 1610). In some embodiments, aligning the user interface with the orientation of the face of the first person comprises forgoing aligning the user interface based on an orientation of the device detected by one or more sensor units 1614 of the device (e.g., with the performing unit 1610), the sensor units 1614 being coupled to the processing unit 1604 and the receiving unit 1602.
In some embodiments, the user interface includes a content item being played, and performing the action on the electronic device in accordance with the identification of the face of the first person comprises associating the playing of the content item with the first person (e.g., with the performing unit 1610). In some embodiments, the processing unit 1604 is further configured to identify, based on the face of the first person in the first image, a first profile on the electronic device that is associated with the face of the first person (e.g., with the identifying unit 1608), wherein associating the playing of the content item with the first person comprises associating the playing of the content item with the first profile (e.g., with the performing unit 1610). In some embodiments, associating the playing of the content item with the first profile comprises updating a play count of the content item in the first profile (e.g., with the performing unit 1610).
In some embodiments, the first image further includes a face of a second person, and the processing unit 1604 is further configured to identify the face of the second person from the first image (e.g., with the identifying unit 1608), identify, based on the face of the second person in the first image, a second profile on the electronic device that is associated with the face of the second person (e.g., with the identifying unit 1608), and associate the playing of the content item with the second profile (e.g., with the performing unit 1610).
