Title: Displaying representations of environments

Abstract:
A method includes displaying a home ER environment characterized by home ER world coordinates, including one or more diorama-view representation of one or more respective ER environments. Each diorama-view representation includes ER objects arranged in a spatial relationship according to corresponding ER world coordinates. In some implementations, in response to detecting an input directed to a first diorama-view representation, the method includes transforming the home ER environment. Transforming the home ER environment includes transforming the spatial relationship between a subset of the ER objects as a function of the home ER world coordinates and corresponding ER world coordinates. In some implementations, in response to detecting an input associated with a first one of a plurality of diorama-view representations, the method includes changing display of the first one of the plurality of diorama-view representations from a first viewing vector to a second viewing vector while maintaining an arrangement of ER objects.

     SUMMARY 
     In accordance with some implementations, a method is performed at an electronic device with one or more processors, a non-transitory memory, one or more input devices, and a display device. The method includes displaying, via the display device, a home enhanced reality (ER) environment characterized by home ER world coordinates, including a first diorama-view representation of a first ER environment. The first diorama-view representation includes one or more of ER objects arranged in a spatial relationship according to first ER world coordinates. The method includes detecting, via the one or more input devices, a first input that is directed to the first diorama-view representation. The method includes, in response to detecting the first input, transforming the home ER environment by: ceasing to display the first diorama-view representation within the home ER environment, transforming the spatial relationship between a subset of the one or more ER objects as a function of the home ER world coordinates and the first ER world coordinates, and displaying, via the display device, the subset of the one or more ER objects within the home ER environment based on the transformation. 
     In accordance with some implementations, a method is performed at an electronic device with one or more processors, a non-transitory memory, one or more input devices, and a display device. The method includes displaying, via the display device, a plurality of diorama-view representations from a corresponding plurality of viewing vectors. The plurality of diorama-view representations corresponds to a plurality of enhanced reality (ER) environments. Each of the plurality of diorama-view representations is associated with a respective set of ER world coordinates that characterizes a respective ER environment. The plurality of diorama-view representations includes a first one of the plurality of diorama-view representations displayed from a first viewing vector. The first one of the plurality of diorama-view representations includes a first one or more of ER objects arranged according to a first set of ER world coordinates. The method includes detecting, via the one or more input devices, an input associated with the first one of the plurality of diorama-view representations. The method includes, in response to detecting the input, changing display of the first one of the plurality of diorama-view representations from the first viewing vector to a second viewing vector while maintaining the first one or more ER objects arranged according to the first set of ER world coordinates. 
     In accordance with some implementations, an electronic device includes one or more processors, a non-transitory memory, one or more input devices, and a display device. The one or more programs are stored in the non-transitory memory and configured to be executed by the one or more processors and the one or more programs include instructions for performing or causing performance of the operations of any of the methods described herein. In accordance with some implementations, a non-transitory computer readable storage medium has stored therein instructions which when executed by one or more processors of an electronic device, cause the device to perform or cause performance of the operations of any of the methods described herein. In accordance with some implementations, an electronic device includes means for performing or causing performance of the operations of any of the methods described herein. In accordance with some implementations, an information processing apparatus, for use in an electronic device, includes means for performing or causing performance of the operations of any of the methods described herein. 
     In some circumstances, a device may display one or more objects within an operating environment. In some applications, the device modifies display of a current operating environment. Modifying the current operating environment may include displaying different (e.g., new) virtual objects at respective predetermined locations within the current operating environment, independent of user input. Displaying a virtual object at a predetermined location within the current operating environment is problematic because the virtual object and a physical (e.g., real-world) object that is also within the current operating environment may obstruct (e.g., occlude) each other, degrading the functionality provided by the current operating environment. 
     By contrast, various implementations include systems, methods, and electronic devices that, in response to detecting a first input directed to a first diorama-view representation of a first ER environment, transforming a subset of ER objects included in the first diorama-view representation into the home ER environment as a function of home ER world coordinates and first ER world coordinates. In some implementations, the method includes moving the subset of ER objects in response to detecting a second input. For example, in some implementations, the method includes moving the subset of ER objects relative to physical objects within the home ER environment. Accordingly, occlusions (e.g., obstructions) between physical objects and ER objects are negated, enabling a richer set of functionality with respect to the home ER environment. 
     In some circumstances, a device may display content within an operating environment. For example, in conventional video conference applications, the operating environment corresponds to a shared communication environment. The device displays remotely-located individuals associated with the shared communication environment based on respective recorded video streams of the individuals. Accordingly, the individuals may graphically interact with each other. The device displays the content within the operating environment in two-dimensions (2D), such as a flat 2D video stream associated with a video conference. However, the device lacks a mechanism for enabling three-dimensional (3D) manipulation of the displayed content within the operating environment. 
     By contrast, various implementations include methods, systems, and electronic devices that enable changing a perspective view of a first one of a plurality of displayed diorama-view representations based on a user input. The plurality of diorama-view representations corresponds to a plurality of enhanced reality (ER) environments. Each of the plurality of diorama-view representations is associated with a respective set of ER world coordinates that characterizes a respective ER environment. Based on the user input, an electronic device changes the perspective view of the first one of the plurality of diorama-view representations while maintaining the previous arrangement of ER objects therein according to a respective set of ER world coordinates. Accordingly, the first one of the plurality of diorama-view representations may be manipulated from a 3D perspective, enabling a richer set of functionality with respect to the ER environments. 
     DESCRIPTION 
     Reference will now be made in detail to implementations, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the various described implementations. However, it will be apparent to one of ordinary skill in the art that the various described implementations may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the implementations. 
     It will also be understood that, although the terms first, second, etc. are, in some instances, used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the scope of the various described implementations. The first contact and the second contact are both contacts, but they are not the same contact, unless the context clearly indicates otherwise. 
     The terminology used in the description of the various described implementations herein is for the purpose of describing particular implementations only and is not intended to be limiting. As used in the description of the various described implementations and the appended claims, the singular forms “a”, “an”, and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes”, “including”, “comprises”, and/or “comprising”, when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     As used herein, the term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting”, depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event]”, depending on the context. 
     Various examples of electronic systems and techniques for using such systems in relation to various enhanced reality technologies are described. 
     A physical setting refers to a world with which various persons can sense and/or interact without use of electronic systems. Physical settings, such as a physical park, include physical elements, such as, for example, physical wildlife, physical trees, and physical plants. Persons can directly sense and/or otherwise interact with the physical setting, for example, using one or more senses including sight, smell, touch, taste, and hearing. 
     An enhanced reality (ER) setting or a computer-generated reality (CGR) setting, in contrast to a physical setting, refers to an entirely (or partly) computer-produced setting that various persons, using an electronic system, can sense and/or otherwise interact with. In ER/CGR, a person&#39;s movements are in part monitored, and, responsive thereto, at least one attribute corresponding to at least one virtual object in the ER/CGR setting is changed in a manner that is consistent with one or more physical laws. For example, in response to an ER/CGR system detecting a person looking upward, the ER/CGR system may adjust various audio and graphics presented to the person in a manner consistent with how such sounds and appearances would change in a physical setting. Adjustments to attribute(s) of virtual object(s) in an ER/CGR setting also may be made, for example, in response to representations of movement (e.g., voice commands). 
     A person may sense and/or interact with an ER/CGR object using one or more senses, such as sight, smell, taste, touch, and sound. For example, a person may sense and/or interact with objects that create a multi-dimensional or spatial acoustic setting. Multi-dimensional or spatial acoustic settings provide a person with a perception of discrete acoustic sources in multi-dimensional space. Such objects may also enable acoustic transparency, which may selectively incorporate audio from a physical setting, either with or without computer-produced audio. In some ER/CGR settings, a person may sense and/or interact with only acoustic objects. 
     Virtual reality (VR) is one example of ER/CGR. A VR setting refers to an enhanced setting that is configured to only include computer-produced sensory inputs for one or more senses. A VR setting includes a plurality of virtual objects that a person may sense and/or interact with. A person may sense and/or interact with virtual objects in the VR setting through a simulation of at least some of the person&#39;s actions within the computer-produced setting, and/or through a simulation of the person or her presence within the computer-produced setting. 
     Mixed reality (MR) is another example of ER/CGR. An MR setting refers to an enhanced setting that is configured to integrate computer-produced sensory inputs (e.g., virtual objects) with sensory inputs from the physical setting, or a representation of sensory inputs from the physical setting. On a reality spectrum, an MR setting is between, but does not include, a completely physical setting at one end and a VR setting at the other end. 
     In some MR settings, computer-produced sensory inputs may be adjusted based on changes to sensory inputs from the physical setting. Moreover, some electronic systems for presenting MR settings may detect location and/or orientation with respect to the physical setting to enable interaction between real objects (i.e., physical elements from the physical setting or representations thereof) and virtual objects. For example, a system may detect movements and adjust computer-produced sensory inputs accordingly, so that, for example, a virtual tree appears fixed with respect to a physical structure. 
     Augmented reality (AR) is an example of MR. An AR setting refers to an enhanced setting where one or more virtual objects are superimposed over a physical setting (or representation thereof). As an example, an electronic system may include an opaque display and one or more imaging sensors for capturing video and/or images of a physical setting. Such video and/or images may be representations of the physical setting, for example. The video and/or images are combined with virtual objects, wherein the combination is then displayed on the opaque display. The physical setting may be viewed by a person, indirectly, via the images and/or video of the physical setting. The person may thus observe the virtual objects superimposed over the physical setting. When a system captures images of a physical setting, and displays an AR setting on an opaque display using the captured images, the displayed images are called a video pass-through. Alternatively, a transparent or semi-transparent display may be included in an electronic system for displaying an AR setting, such that an individual may view the physical setting directly through the transparent or semi-transparent displays. Virtual objects may be displayed on the semi-transparent or transparent display, such that an individual observes virtual objects superimposed over a physical setting. In yet another example, a projection system may be utilized in order to project virtual objects onto a physical setting. For example, virtual objects may be projected on a physical surface, or as a holograph, such that an individual observes the virtual objects superimposed over the physical setting. 
     An AR setting also may refer to an enhanced setting in which a representation of a physical setting is modified by computer-produced sensory data. As an example, at least a portion of a representation of a physical setting may be graphically modified (e.g., enlarged), so that the modified portion is still representative of (although not a fully-reproduced version of) the originally captured image(s). Alternatively, in providing video pass-through, one or more sensor images may be modified in order to impose a specific viewpoint different than a viewpoint captured by the image sensor(s). As another example, portions of a representation of a physical setting may be altered by graphically obscuring or excluding the portions. 
     Augmented virtuality (AV) is another example of MR. An AV setting refers to an enhanced setting in which a virtual or computer-produced setting integrates one or more sensory inputs from a physical setting. Such sensory input(s) may include representations of one or more characteristics of a physical setting. A virtual object may, for example, incorporate a color associated with a physical element captured by imaging sensor(s). Alternatively, a virtual object may adopt characteristics consistent with, for example, current weather conditions corresponding to a physical setting, such as weather conditions identified via imaging, online weather information, and/or weather-related sensors. As another example, an AR park may include virtual structures, plants, and trees, although animals within the AR park setting may include features accurately reproduced from images of physical animals. 
     Various systems allow persons to sense and/or interact with ER/CGR settings. For example, a head mounted system may include one or more speakers and an opaque display. As another example, an external display (e.g., a smartphone) may be incorporated within a head mounted system. The head mounted system may include microphones for capturing audio of a physical setting, and/or image sensors for capturing images/video of the physical setting. A transparent or semi-transparent display may also be included in the head mounted system. The semi-transparent or transparent display may, for example, include a substrate through which light (representative of images) is directed to a person&#39;s eyes. The display may also incorporate LEDs, OLEDs, liquid crystal on silicon, a laser scanning light source, a digital light projector, or any combination thereof. The substrate through which light is transmitted may be an optical reflector, holographic substrate, light waveguide, optical combiner, or any combination thereof. The transparent or semi-transparent display may, for example, transition selectively between a transparent/semi-transparent state and an opaque state. As another example, the electronic system may be a projection-based system. In a projection-based system, retinal projection may be used to project images onto a person&#39;s retina. Alternatively, a projection-based system also may project virtual objects into a physical setting, for example, such as projecting virtual objects as a holograph or onto a physical surface. Other examples of ER/CGR systems include windows configured to display graphics, headphones, earphones, speaker arrangements, lenses configured to display graphics, heads up displays, automotive windshields configured to display graphics, input mechanisms (e.g., controllers with or without haptic functionality), desktop or laptop computers, tablets, or smartphones.

The electronic device  100  includes memory  102  (which optionally includes one or more computer readable storage mediums), a memory controller  122 , one or more processing units (CPUs)  120 , a peripherals interface  118 , an input/output (I/O) subsystem  106 , a speaker  111 , a touch-sensitive display system  112 , an inertial measurement unit (IMU)  130 , image sensor(s)  143  (e.g., camera), contact intensity sensor(s)  165 , audio sensor(s)  113  (e.g., microphone), eye tracking sensor(s)  164  (e.g., included within a head-mountable device (HMD)), a hand tracking sensor  150 , a body pose sensor  190 , and other input or control device(s)  116 . In some implementations, the electronic device  100  corresponds to one of a mobile phone, tablet, laptop, wearable computing device, head-mountable device (HMD), head-mountable enclosure (e.g. the electronic device  100  slides into or otherwise attaches to a head-mountable enclosure), or the like. In some implementations, the head-mountable enclosure is shaped to form a receptacle for receiving the electronic device  100  with a display. 
     In some implementations, the peripherals interface  118 , the one or more processing units  120 , and the memory controller  122  are, optionally, implemented on a single chip, such as a chip  103 . In some other implementations, they are, optionally, implemented on separate chips. 
     The I/O subsystem  106  couples input/output peripherals on the electronic device  100 , such as the touch-sensitive display system  112  and the other input or control devices  116 , with the peripherals interface  118 . The I/O subsystem  106  optionally includes a display controller  156 , an image sensor controller  158 , an intensity sensor controller  159 , an audio controller  157 , an eye tracking controller  162 , one or more input controllers  160  for other input or control devices, an IMU controller  132 , a hand tracking controller  180 , a body pose controller  195 , and a privacy subsystem  170 . The one or more input controllers  160  receive/send electrical signals from/to the other input or control devices  116 . The other input or 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 implementations, the one or more input controllers  160  are, optionally, coupled with any (or none) of the following: a keyboard, infrared port, Universal Serial Bus (USB) port, stylus, and/or a pointer device such as a mouse. The one or more buttons optionally include an up/down button for volume control of the speaker  111  and/or audio sensor(s)  113 . The one or more buttons optionally include a push button. In some implementations, the other input or control devices  116  includes a positional system (e.g., GPS) that obtains information concerning the location and/or orientation of the electronic device  100  relative to a physical environment. 
     The touch-sensitive display system  112  provides an input interface and an output interface between the electronic device  100  and a user. The display controller  156  receives and/or sends electrical signals from/to the touch-sensitive display system  112 . The touch-sensitive display system  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 implementations, some or all of the visual output corresponds to user interface objects. As used herein, the term “affordance” refers to a user-interactive graphical user interface object (e.g., a graphical user interface object that is configured to respond to inputs directed toward the graphical user interface object). Examples of user-interactive graphical user interface objects include, without limitation, a button, slider, icon, selectable menu item, switch, hyperlink, or other user interface control. 
     The touch-sensitive display system  112  has a touch-sensitive surface, sensor, or set of sensors that accepts input from the user based on haptic and/or tactile contact. The touch-sensitive display system  112  and the display controller  156  (along with any associated modules and/or sets of instructions in the memory  102 ) detect contact (and any movement or breaking of the contact) on the touch-sensitive display system  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 the touch-sensitive display system  112 . In an example implementation, a point of contact between the touch-sensitive display system  112  and the user corresponds to a finger of the user or a stylus. 
     The touch-sensitive display system  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 implementations. The touch-sensitive display system  112  and the 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 the touch-sensitive display system  112 . 
     The user optionally makes contact with the touch-sensitive display system  112  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some implementations, the user interface is designed to work 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 implementations, the electronic device  100  translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     The speaker  111  and the audio sensor(s)  113  provide an audio interface between a user and the electronic device  100 . Audio circuitry receives audio data from the peripherals interface  118 , converts the audio data to an electrical signal, and transmits the electrical signal to the speaker  111 . The speaker  111  converts the electrical signal to human-audible sound waves. Audio circuitry also receives electrical signals converted by the audio sensors  113  (e.g., a microphone) from sound waves. Audio circuitry converts the electrical signal to audio data and transmits the audio data to the peripherals interface  118  for processing. Audio data is, optionally, retrieved from and/or transmitted to the memory  102  and/or RF circuitry by the peripherals interface  118 . In some implementations, audio circuitry also includes a headset jack. The headset jack provides an interface between audio circuitry 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). 
     The inertial measurement unit (IMU)  130  includes accelerometers, gyroscopes, and/or magnetometers in order measure various forces, angular rates, and/or magnetic field information with respect to the electronic device  100 . Accordingly, according to various implementations, the IMU detects one or more positional change inputs of the electronic device  100 , such as the electronic device  100  being shaken, rotated, moved in a particular direction, and/or the like. 
     The image sensor(s)  143  capture still images and/or video. In some implementations, an image sensor  143  is located on the back of the electronic device  100 , opposite a touch screen on the front of the electronic device  100 , so that the touch screen is enabled for use as a viewfinder for still and/or video image acquisition. In some implementations, another image sensor  143  is located on the front of the electronic device  100  so that the user&#39;s image is obtained (e.g., for selfies, for videoconferencing while the user views the other video conference participants on the touch screen, etc.). In some implementations, the image sensor(s) are integrated within a HMD. 
     The contact intensity sensors  165  detect intensity of contacts on the electronic device  100  (e.g., a touch input on a touch-sensitive surface of the electronic device  100 ). The contact intensity sensors  165  are coupled with the intensity sensor controller  159  in the I/O subsystem  106 . The contact intensity sensor(s)  165  optionally include 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). The contact intensity sensor(s)  165  receive contact intensity information (e.g., pressure information or a proxy for pressure information) from the physical environment. In some implementations, at least one contact intensity sensor  165  is collocated with, or proximate to, a touch-sensitive surface of the electronic device  100 . In some implementations, at least one contact intensity sensor  165  is located on the back of the electronic device  100 . 
     The eye tracking sensor(s)  164  detect eye gaze of a user of the electronic device  100  and generate eye tracking data indicative of the eye gaze of the user. In various implementations, the eye tracking data includes data indicative of a fixation point (e.g., point of regard) of the user on a display panel, such as a display panel within a head-mountable device (HMD), a head-mountable enclosure, or within a heads-up display. 
     The hand tracking sensor  150  obtains hand tracking data indicative of a position of a hand of a user. In various implementations, the electronic device  100  utilizes the hand tracking data in order to manipulate display of a diorama-view representation of an ER environment. For example, in some implementations, the electronic device  100  moves the diorama-view representation in order to track the current position of the hand of the user. As another example, the electronic device 
     The body pose sensor  190  obtains body pose data indicative of a position of a head or body of a user. In various implementations, the electronic device  100  utilizes the body pose data in order to manipulate display of a diorama-view representation of an ER environment. For example, the body pose data indicates the user is turning his/her head sideways, and the electronic device  100  accordingly manipulates the perspective view of the diorama-view representation of the ER environment. 
     In various implementations, the electronic device  100  includes a privacy subsystem  170  that includes one or more privacy setting filters associated with user information, such as user information included in the eye gaze data and/or body position data associated with a user. In some implementations, the privacy subsystem  170  selectively prevents and/or limits the electronic device  100  or portions thereof from obtaining and/or transmitting the user information. To this end, the privacy subsystem  170  receives user preferences and/or selections from the user in response to prompting the user for the same. In some implementations, the privacy subsystem  170  prevents the electronic device  100  from obtaining and/or transmitting the user information unless and until the privacy subsystem  170  obtains informed consent from the user. In some implementations, the privacy subsystem  170  anonymizes (e.g., scrambles or obscures) certain types of user information. For example, the privacy subsystem  170  receives user inputs designating which types of user information the privacy subsystem  170  anonymizes. As another example, the privacy subsystem  170  anonymizes certain types of user information likely to include sensitive and/or identifying information, independent of user designation (e.g., automatically). As yet another example, the privacy system  170  denies access to a first individual having a first access level that does not satisfy an access level criterion that is associated with an ER session, and allows access to a second individual having a second access level that satisfies the access level criterion. 
       FIGS.  2 A- 2 V  are examples of an operating environment  200  in accordance with some implementations. While pertinent features are shown, those of ordinary skill in the art will appreciate from the present disclosure that various other features have not been illustrated for the sake of brevity and so as not to obscure more pertinent aspects of the example implementations disclosed herein. 
     To that end, as illustrated in  FIG.  2 A , the operating environment  200  includes an electronic device  203 , which is being held by a user  210 , and a physical table  220 . In some implementations, the electronic device  203  corresponds to a mobile device, such as a smartphone, laptop, tablet, etc. In some implementations, the electronic device  203  is similar to and adapted from the electronic device  100  in  FIG.  1   . The electronic device  203  is associated with a field-of-view  204  associated with a portion of the operating environment  200 . 
     According to various implementations, the electronic device  203  is configured to present a home ER environment  206  to the user  210 . The home ER environment  206  is characterized by home ER world coordinates  208 . In some implementations, the home ER world coordinates  208  define a set of points existing in a three-dimensional (3D) space. In some implementations, the home ER environment  206  corresponds to a purely virtual environment, and thus the electronic device  203  does not display the physical table  220  within the home ER environment  206 , irrespective of the position of the electronic device  203  relative to the operating environment  200 . 
     In some implementations, the home ER environment  206  corresponds to an AR environment. For example, in some implementations, the electronic device  203  is configured to present the home ER environment  206  and to enable video pass-through of at least a portion of physical objects within the operating environment  200  therein. As one example, with reference to  FIG.  2 F , after the user  210  wearing an electronic device  203  has rotated the orientation of the electronic device  203  towards the physical table  220 , the electronic device  203  displays the physical table  220  within the home ER environment  206 . As another example, in some implementations, the electronic device  203  includes a transparent or additive display that enables optical see-through of the operating environment  200  including physical objects within the operating environment  200 . 
     The home ER environment  206  includes a first diorama-view representation  230  of a first ER environment and a second diorama-view representation  240  of a second ER environment. In some implementations, a diorama-view representation is representative of a purely virtual environment. On the other hand, in some implementations, a diorama-view representation is at least partially representative of a real environment. For example, in some implementations, a diorama-view representation includes structure features of a real environment, such as the walls, floor, and ceiling of a user&#39;s living room. As another example, in some implementations, a diorama-view representation includes physical objects that are within virtual structural features, such as a real table inside a virtual room. 
     The first diorama-view representation  230  includes one or more of ER objects arranged in a spatial relationship according to first ER world coordinates  232 . For example, the first ER world coordinates  232  define a respective set of points existing in a 3D space. Namely, the first diorama-view representation  230  includes a television  234 , an avatar  236 , and a couch  238 . The avatar  236  corresponds to a virtual representation of an individual that is associated with (e.g., connected to) the first ER environment. For example, in some implementations, the avatar  236  is associated with an ER session that enables graphical representations of individuals to be displayed within the first ER environment. In some implementations, the electronic device  203  dynamically updates the first diorama-view representation  230 , such as playback of video content via the television  234  or movement of the avatar  236 , in order to reflect changes within the first ER environment. 
     The second diorama-view representation  240  includes one or more of ER objects arranged in a spatial relationship according to second ER world coordinates  242 . Namely, the second diorama-view representation  240  includes a credenza  244  and a chair  246 . For example, the second ER world coordinates  242  define a respective set of points existing in a 3D space. One of ordinary skill in the art will appreciate that the diorama-view representations may include any number and types of ER objects arranged in a variety of ways. One of ordinary skill in the art will appreciate that the diorama-view representations may include any number of avatars. 
     In some implementations, the electronic device  203  corresponds to a head-mountable device (HMD) being worn by the user  210 . The HMD presents the home ER environment  206  described above with reference to  FIG.  2 A . In some implementations, the HMD includes an image sensor that is associated with the field-of-view  204 , and the HMD displays, within the home ER environment  206 , AR content that includes physical objects. In some implementations, the HMD is similar to and adapted from the electronic device  100  in  FIG.  1   . In some implementations, the HMD is configured to present the home ER environment  206  and to enable video pass-through of at least a portion of physical objects within the operating environment  200  therein. As another example, in some implementations, the HMD includes a transparent or additive display enables optical see-through of the operating environment  200  including physical objects within the operating environment  200 . 
     In some implementations, the HMD includes an integrated display (e.g., a built-in display) that displays the home ER environment  206 . In some implementations, the HMD includes a head-mountable enclosure. In various implementations, the head-mountable enclosure includes an attachment region to which another device with a display can be attached. In various implementations, the head-mountable enclosure is shaped to form a receptacle for receiving another device that includes a display (e.g., the electronic device  203  illustrated in  FIG.  2 A ). For example, in some implementations, the electronic device  203  slides/snaps into or otherwise attaches to the head-mountable enclosure. In some implementations, the display of the device attached to the head-mountable enclosure presents (e.g., displays) the home ER environment  206 . 
       FIGS.  2 B- 2 H  illustrate changing respective perspective views of the first diorama-view representation  230  and the second diorama-view representation  240  based on various user inputs. As illustrated in  FIG.  2 B , the electronic device  203  detects an input  250  associated with the second diorama-view representation  240 . The input  250  requests to move the second diorama-view representation  240  upward along the z-axis of the home ER world coordinates  208  to a position above the first diorama-view representation  230 . For example, in some implementations, an eye tracking sensor of (e.g., integrated within) the electronic device  203  detects the input  250 , wherein the input  250  corresponds to an eye gaze input that indicates that an eye gaze of the user  210  is directed towards the second diorama-view representation  240 . As another example, in some implementations, a hand tracking sensor of (e.g., integrated within) the electronic device  203  detects the input  250 , wherein the input  250  corresponds to a hand tracking motion made by the user  210  that is directed towards the second diorama-view representation  240 . 
     In response to detecting the input  250  in  FIG.  2 B , the electronic device  203  changes display of the second diorama-view representation  240  from a first viewing vector to a second viewing vector by moving the second diorama-view representation  240  to a position above the first diorama-view representation  230 , as illustrated in  FIG.  2 C . A viewing vector provides one or more of a field-of-view (FOV), pose/rotational coordinates, translational coordinates, perspective, and/or the like relative to the user  210  and the home ER coordinate system  208 . While changing display of the second diorama-view representation  240  from the first viewing vector to the second viewing vector, the electronic device  203  maintains the credenza  244  and the chair  246  according to the second ER world coordinates  242 . In other words, the electronic device  203  maintains the spatial relationship between the credenza  244  and the chair  246  within the second diorama-view representation  240 . For example, as illustrated in  FIGS.  2 B and  2 C , the longer edge of the credenza  244  runs substantially along (e.g., parallel to) the y-axis of the second ER world coordinates  242 . As another example, as illustrated in  FIGS.  2 B and  2 C , the bottom of the legs of the credenza  244  and the bottom of the legs of the chair  246  are at the z=0 location of the z-axis of the second ER world coordinates  242 . As yet another example, the electronic device  203  maintains respective position of the credenza  244  and the chair  246  relative to each other along the x-y plane of the second ER world coordinates  242  in  FIGS.  2 B and  2 C . 
     As illustrated in  FIG.  2 D , the electronic device  203  detects a movement input  251 , such as via an IMU of the electronic device  203 . The movement input  251  corresponds to the user  210  moving clockwise (as viewed from above) around the first diorama-view representation  230  and the second diorama-view representation  240  within the operating environment  200 . In response to detecting the movement input  251  in  FIG.  2 D , the field-of-view  204  associated with the electronic device  203  and thus the displayed home ER environment  206  includes a portion of the physical table  220 , as is illustrated in  FIG.  2 E . 
     In further response to detecting the movement input  251  in  FIG.  2 D , the electronic device  203  changes display of the first diorama-view representation  230  and the second diorama-view representation  240  according to the rotation of the home ER environment  206 , as illustrated in  FIG.  2 E . Namely, the electronic device  203  rotates the first diorama-view representation  230  and the ER objects therein (e.g., the television  234 , the avatar  236 , and the couch  238 ) 90-degrees according to the corresponding rotation of the home ER world coordinates  208 , as indicated by rotation of the first ER world coordinates  232  between  FIG.  2 D  and  FIG.  2 E . For example, the view of the avatar  236  changes from a front-view of the avatar  236  in  FIG.  2 D  to a side-view of the avatar  236  in  FIG.  2 E . While rotating the first diorama-view representation  230 , the electronic device  203  maintains the television  234 , the avatar  236 , and the couch  238  according to the first ER world coordinates  232 . In other words, the electronic device  203  maintains the spatial relationship between the television  234 , the avatar  236 , and the couch  238  within the first diorama-view representation  230 . 
     Moreover, as illustrated in  FIG.  2 E , the electronic device  203  rotates the second diorama-view representation  240  and the ER objects therein (e.g., the credenza  244  and the chair  246 ) 90-degrees according to the corresponding rotation of the home ER world coordinates  208 , as indicated by rotation of the second ER world coordinates  242  between  FIG.  2 D  and  FIG.  2 E . For example, the view of the credenza  244  changes from a front-view of the credenza  244  in  FIG.  2 D  to a side-view of the credenza  244  in  FIG.  2 E . While rotating the second diorama-view representation  240 , the electronic device  203  maintains the credenza  244  and the chair  246  according to the second ER world coordinates  242 . In other words, the electronic device  203  maintains the spatial relationship between the credenza  244  and the chair  246  within the second diorama-view representation  240 . 
     As illustrated in  FIG.  2 F , the electronic device  203  detects a selection input  252  directed to the first diorama-view representation  230 . For example, the selection input  252  is detected by an eye tracking sensor of the electronic device  203  or by a hand tracking sensor of the electronic device  203 . In response to detecting the selection input  252  in  FIG.  2 F , the electronic device  203  ceases to display the second diorama-view representation  240  and maintains display of the first diorama-view representation  230 , as illustrated in  FIG.  2 G . 
     As illustrated in  FIG.  2 H , the electronic device  203  detects a manipulation input  253  directed to the first diorama-view representation  230 . The manipulation input  253  rotates the first diorama-view representation  230  90-degrees counterclockwise (as viewed from above) relative to the home ER world coordinates  208 . Accordingly, as illustrated in  FIGS.  2 H and  2 I , the first ER world coordinates  232  associated with the first diorama-view representation  230  rotate according to the manipulation input  253 , whereas the home ER world coordinates  208  do not change. Accordingly, the respective views of the television  234 , the avatar  236 , and the couch  238  change from a side-view to a front-view between  FIGS.  2 H and  2 I . 
       FIGS.  2 J- 2 N  illustrate functionality associated with an ER session that is associated with the first ER environment. The ER session enables respective graphical representations of individuals to be concurrently within the first ER environment. For example, the ER session enables a particular individual that is represented by the avatar  236  to be within the first ER environment. In some implementations, the electronic device  203  receives a request to join an ER session and displays a corresponding indication. For example, in some implementations, the indication corresponds to an ER join interface  254 , as illustrated in  FIG.  2 J . Moreover, as illustrated in  FIG.  2 J , the electronic device  203  plays (e.g., via a speaker) a first set of speech data  256  that is associated with the particular individual that is associated with (e.g., connected to) the ER session. For example, the first set of speech data  256  is a verbal request to join the ER session, such as “Hey, Bob. Come join my ER environment and we can virtually watch TV together.” As another example, the first set of speech data  256  include ambient noise associated with the first ER environment, such as noise from the television  234 . 
     As illustrated in  FIGS.  2 K and  2 L , the electronic device  203  displays an animation of the avatar  236  based on a corresponding movement of the particular individual. As illustrated in  FIG.  2 K , the avatar  236  moves from standing beside the couch  238  to sitting on the couch  238  facing the television  234 , as is indicated by movement arrow  257 , which is illustrated for purely explanatory purposes. Accordingly, as illustrated in  FIG.  2 L , the electronic device  203  displays the first diorama-view representation  230  with the avatar  236  having moved from beside the couch  238  to sitting on the couch  238  and facing the television  234 . 
     As illustrated in  FIG.  2 M , the electronic device  203  obtains (e.g., via an audio sensor) a second set of speech data  258  from the user  210  and provides the second set of speech data  258  to the particular individual. For example, the second set of speech data  258  is a verbal affirmation to join the ER session, such as “Hey, Jill. Sure, I will join your ER environment. I want to watch the baseball game on TV.” 
       FIGS.  2 N- 2 V  illustrate transforming a spatial relationship between a subset of the ER objects within the first diorama-view representation  230  as a function of the first ER world coordinates  232  and the home ER world coordinates  208 . As illustrated in  FIG.  2 N , the first diorama-view representation  230  has a first height value indicated by a first reference measurement  260   a , which is illustrated for purely explanatory purposes. 
     As illustrated in  FIG.  2 N , the electronic device  203  detects an acceptance input  259  that accepts the request to join the ER session. In response to detecting the acceptance input  259  in  FIG.  2 N , the electronic device  203 : ceases to display the first diorama-view representation  230 , transforms a subset of the ER objects within the first diorama-view representation  230  as a function of the first ER world coordinates  232  and the home ER world coordinates  208 , and displays the subset of the ER objects based on the transformation, as illustrated in  FIG.  2 O . In some implementations, as illustrated in  FIG.  2 O , the electronic device  203  displays the subset of the ER objects within a bounded ER environment  261 . As illustrated in  FIG.  2 O , the bounded ER environment  261  has a second height value indicated by a second reference measurement  260   b , which is illustrated for purely explanatory purposes. Notably, as illustrated in  FIG.  2 O , the second height value indicated by the second reference measurement  260   b  is larger than the first height value indicated by the first reference measurement  260   a . One of ordinary skill in the art will appreciate that other dimensional components (e.g., depth and width) of the bounded ER environment  261  are larger than corresponding dimensional components of the first diorama-view representation  230 . 
     Displaying the bounded ER environment  261  may assist the user  210  in repositioning the subset of the ER objects in order to avoid physical objects and thus avoid visual obstructions, as will be described below. In some implementations, the electronic device  203  displays the subset of the ER objects without the bounded ER environment  261 . 
     As illustrated in  FIG.  2 O , the subset of the ER objects includes a transformed television  264  that is based on the television  234 , a transformed avatar  266  that is based on the avatar  236 , and a transformed couch  268  that is based on the couch  238 . The transformed television  264 , the transformed avatar  266 , and the transformed couch  268  are arranged according to transformed ER world coordinates  262  that are based on the first ER world coordinates  232 . As compared with the first diorama-view representation  230  and the ER objects therein, the bounded ER environment  261  and the subset of the ER objects therein more accurately represent ER objects that may later be merged into or replace the home ER environment  206 . For example, in some implementations, transforming the subset of the ER objects corresponds to enlarging each of the subset of the ER objects by a scaling factor. The scaling factor may be predetermined or may be specified by a user input. For example, in some implementations, the scaling factor corresponds to true-scale. In this example, the subset of the ER objects appears substantially equivalent to how they would after being merged into or replacing the home ER environment  206 . 
     In some implementations, electronic device  203  arranges the transformed television  264 , the transformed avatar  266 , and the transformed couch  268  in order to match (within an error threshold) the corresponding arrangement of the television  234 , the avatar  236 , and the couch  238  within the first diorama-view representation  230  as defined by the first ER world coordinates  232  and the home ER world coordinates  208 . For example, as compared with the corresponding ER objects within the first diorama-view representation  230  illustrated in  FIG.  2 N , the subset of the ER objects ( 264 ,  266 ,  268 ) illustrated in  FIG.  2 O  are similarly located and oriented relative to each other. 
     In some implementations, transformation of the subset of the ER objects results in the relative distances between the transformed television  264 , the transformed avatar  266 , and the transformed couch  268  matching relative distances of the corresponding ER objects within the first diorama-view representation  230  within an error threshold. 
     In some implementations, transformation of the subset of the ER objects corresponds to changing resolutions of some or all of the subset of the ER objects. For example, in some implementations, the electronic device  203  performs object identification (e.g., semantic segmentation or object tracking) in order to identify dynamic ER objects (e.g., the avatar  236 ), and reduces resolutions of static ER objects (e.g., the couch  238 ). 
     In some implementations, the bounded ER environment  261  and the subset of the ER objects are obscured by one or more physical objects within the home ER environment  206 . For example, as illustrated in  FIG.  2 O , the bounded ER environment  261  and the subset of the ER objects are initially displayed along a back wall of the home ER environment  206 . Accordingly, were the user  210  to request to merge the subset of the ER objects into the home ER environment  206 , the transformed television  264  would be behind and therefore blocked by the back wall, degrading the experience of the user  210 . Accordingly, according to various implementations, the electronic device  203  enables movement of the subset of the ER objects in order to avoid physical obstructions. 
     For example, referring to  FIG.  2 P , the electronic device  203  detects an input  270  that corresponds to moving the bounded ER environment  261  and the subset of the ER objects therein away from the back wall of the home ER environment  206 . In response to detecting the input  270  in  FIG.  2 P , the electronic device  203  moves the bounded ER environment  261  and the subset of the ER objects therein away from the back wall to above the physical table  220 , as illustrated in  FIG.  2 Q . However, as illustrated in  FIG.  2 Q , the transformed avatar  266  and the transformed couch  268  obstruct a portion of the physical table  220 . 
     As illustrated in  FIG.  2 R , the electronic device  203  detects an input  272  that corresponds to further moving the bounded ER environment  261  and the subset of the ER objects therein down along the z-axis of the home ER world coordinates  208  away from the physical table  220 . In response to detecting the input  272  in  FIG.  2 R , the electronic device  203  moves the bounded ER environment  261  and the ER objects therein down along the z-axis of the home ER world coordinates  208 . Accordingly, as illustrated in  FIG.  2 S , the transformed avatar  266  and the transformed couch  268  no longer obstruct the physical table  220 , improving the experience of the user  210 . 
     As illustrated in  FIG.  2 T , the electronic device  203  detects an input  274  directed to the bounded ER environment  261 . The input  274  corresponds to a request to enter the first ER environment. In some implementations, in response to detecting the input  274  in  FIG.  2 T , the electronic device  203  adds a true-scale (e.g., full-size) television  282 , a true-scale avatar  284 , and a true-scale couch  286  to the home ER environment  206 , as illustrated in  FIG.  2 U . Notably, as illustrated in  FIG.  2 U , the true-scale television  282  is within the field-of-view  204 , but the true-scale avatar  284  and the true-scale couch  286  are not. However, were the user  210  to rotate the electronic device  203  clockwise 90 degrees (as viewed from above), such as by turning his or her head towards the true-scale avatar  284 , then the true-scale avatar  284  and the true-scale couch  286  would be within the field-of-view  204 . 
     In some implementations, adding the subset of the ER objects to the home ER environment  206  corresponds to resizing the subset of the ER objects to true-scale. As illustrated in  FIG.  2 U , the transformed avatar  266  and the transformed couch  268  do not obstruct the physical table  220 . Accordingly, the user  210  may interact with the true-scale ER objects independent of providing additional inputs, leading to a more pleasant experience and reducing processor, memory, and battery utilization of the electronic device  203 . 
     In some implementations, in response to detecting the input  274  in  FIG.  2 T , the electronic device  203  replaces the home ER environment  206  with the first ER environment  290 , such as when the first ER environment  290  is a pure VR environment, as illustrated in  FIG.  2 V . The first ER environment  290  includes the true-scale television  282 , the true-scale avatar  284 , and the true-scale couch  286 , but not the physical table  220 . 
       FIG.  3    is a flow diagram of a method  300  of changing a perspective view of a diorama-view representation of an ER environment based on a user input in accordance with some implementations. In various implementations, the method  300  or portions thereof are performed by an electronic device (e.g., the electronic device  100  in  FIG.  1    or the electronic device  203  in  FIGS.  2 A- 2 V ). In various implementations, the method  300  or portions thereof are performed by an HMD. In some implementations, the method  300  is performed by processing logic, including hardware, firmware, software, or a combination thereof. In some implementations, the method  300  is performed by a processor executing code stored in a non-transitory computer-readable medium (e.g., a memory). In various implementations, some operations in method  300  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As represented by block  302 , in some implementations, the method  300  includes generating a plurality of diorama-view representations respectively corresponding to a plurality of ER environments. In some implementations, the method  300  includes obtaining a plurality of characterization vectors that respectively provide a plurality of spatial characterizations of the corresponding plurality of ER environments. Each of the plurality of characterization vectors includes a plurality of object label values that respectively identify one or more ER objects. Each of the plurality of characterization vectors also includes a plurality of relative position values providing respective positions of the one or more ER objects relative to each other. Moreover, the method  300  includes generating, from the corresponding plurality of ER environments and the plurality of characterization vectors, the plurality of diorama-view representations of the corresponding plurality of ER environments according to the relative position values. For example, an object label value may include instance object label values and/or semantic object label values. As another example, an object label value may include one sub-value or multiple sub-values. As yet example, a particular volumetric region of an ER environment may include three objects and thus has three corresponding object label values, such as “first object,” “second object,” and “third object.” An object label value may be associated with an object and/or a feature thereof (e.g., table, chair, corner, edge, etc.). Moreover, an object label value may identify a moving object, such as an avatar of a particular individual within the ER environment. In some implementations, the spatial characterization corresponds to a volumetric (e.g., three-dimensional (3D)) characterization. 
     In some implementations, generating the plurality of diorama-view representations is based on a scaling factor, such as scaling down the corresponding plurality of ER environments by a scaling factor. For example, in some implementations, the scaling factor is predetermined. As another example, the scaling factor is obtained via a user input, such as an input that is directed to an affordance of a touch-sensitive surface of the electronic device or an input that corresponds to an eye gaze location of a user. As yet another example, in some implementations, the method  300  includes determining the scaling factor based on physical objects within a physical environment. To that end, in some implementations, the method  300  includes obtaining, via the image sensor, pass-through image data bounded by a field-of-view of a physical environment associated with the image sensor; identifying, within the pass-through image data, one or more physical objects within the physical environment; and determining the scaling factor based on the one or more physical objects. For example, the scaling factor may be based on respective positions and/or sizes (e.g., volumes) of the one or more physical objects, such as scaling down more when there are relatively large physical objects within the physical environment. In some implementations, the scaling factor is based on dimensions (e.g., volume) of a respective ER environment. 
     As represented by block  304 , the method  300  includes displaying, via a display device, the plurality of diorama-view representations from a corresponding plurality of viewing vectors. The plurality of diorama-view representations corresponds to a plurality of enhanced reality (ER) environments. Each of the plurality of diorama-view representations is associated with a respective set of ER world coordinates that characterizes a respective ER environment. The plurality of diorama-view representations includes a first one of the plurality of diorama-view representations displayed from a first viewing vector. The first one of the plurality of diorama-view representations includes a first one or more of ER objects arranged according to a first set of ER world coordinates. As another example, each of the plurality of diorama-view representations corresponds to a bounded region associated with a respective set of ER world coordinates. The orientation, position, location, etc. of a particular plurality of ER objects within a corresponding diorama-view representation is based on the respective set of ER world coordinates. The ER objects may include a combination of movable inanimate objects (e.g., a chair or table), living objects (e.g., one or more avatars representing an individual), and inanimate structural objects (e.g., ceiling, wall, boundary of the diorama-view representation). In some implementations, the electronic device displays the plurality of diorama-view representations in accordance with determining satisfaction of a spatial proximity threshold. For example, diorama-view representations are spaced sufficiently far away from each other so as to avoid obscuring each other. A particular viewing vector provides one or more of: a field-of-view (FOV), pose/rotational coordinates, translational coordinates, a perspective, and/or the like. 
     In some implementations, the method  300  includes displaying the plurality of diorama-view representations within a home ER environment, such as the home ER environment  206  in  FIGS.  2 A- 2 V . As one example, with reference to  FIG.  2 A , the electronic device  203  displays a first diorama-view representation  230  of a first ER environment and a second diorama-view representation  240  of a second ER environment within the home ER environment  206 . Continuing with this example, the first diorama-view representation  230  includes a television  234 , an avatar  236 , and a couch  238  arranged according to first ER world coordinates  232 . Continuing with this example, the second diorama-view representation  240  includes a credenza  244  and a chair  246  arranged according to second ER world coordinates  242 . 
     In some implementations, the method  300  includes displaying, within a particular one of the plurality of diorama-view representations, a recording of activity within a respective ER environment associated with the particular one of the plurality of diorama-view representations. In some implementations, the recording includes activity within the particular one of the plurality of diorama-view representations over a previous span of time. For example, the recording includes activity over the last day, indicating that five people entered and left a respective ER environment and three of those people drew on a whiteboard within the respective ER environment. 
     In some implementations, the electronic device displays the plurality of diorama-view representations based on control values. For example, the control values may be set via a user input. Control values may include, for example, a combination of whether or not to mute audio, whether a previewing user may communicate with individuals who have joined the first ER session, and/or whether the previewing user sees a history (e.g., log) of who has joined and left and when. 
     In some implementations, the electronic device displays the plurality of diorama-view representations based on eye gaze data. To that end, the method  300  includes obtaining eye gaze data indicative of an eye gaze location, wherein displaying the plurality of diorama-view representations is based on the eye gaze data. For example, an electronic device renders and displays a particular one of the plurality of diorama-view representation with high resolution (e.g., emphasized) when the eye gaze data indicates that the eye gaze location is closest to the particular one of the a plurality of diorama-view representation. As another example, the electronic device does not display another one of the plurality of diorama-view representation when the eye gaze data indicates that the eye gaze location has not been within a threshold distance from the other one of the plurality of diorama-view representation for a threshold amount of time. As yet another example, the electronic device ceases performing live updates on (e.g., keeping static) contents of a portion of the plurality of diorama-view representations that are not within a threshold distance from the eye gaze location. 
     As represented by block  306 , in some implementations, the plurality of diorama-view representations corresponds to reduced-sized representations of the corresponding plurality of ER environments. As one example, the television  234  within the first diorama-view representation  230  illustrated in  FIG.  2 N  corresponds to a reduced-sized version of the true-scale television  282  illustrated in  FIG.  2 U . In some implementations, the number of ER objects within a particular diorama-view representation is the same as or fewer than the number of ER objects with a corresponding ER environment. For example, the method  300  includes selectively rendering and/or displaying certain objects, such as displaying living objects (e.g., the avatar  236 ), but not rendering structural features (e.g., walls) of the home ER environment. In some implementations, the method  300  includes rendering different features of a particular diorama-view representation with different level of fidelity (e.g., resolution). By selectively rendering and/or displaying, an electronic device reduces utilization of processing and battery resources. 
     As represented by block  308 , in some implementations, displaying the plurality of diorama-view representations includes animating a portion of the plurality of diorama-view representations. As one example, with reference to  FIGS.  2 K and  2 L , the electronic device  203  displays movement of the avatar  236  because an individual associated with the avatar  236  is moving within his or her respective physical environment, causing a resulting movement of his or her avatar  236  within the ER environment. 
     As represented by block  310 , in some implementations, at least a subset of the corresponding plurality of ER environments is respectively associated with a plurality of ER environments corresponding to a plurality of ER sessions. Each of the plurality of ER environments enables graphical representations of individuals to be concurrently within the ER environment. According to various implementations, each of the one or more corresponding individuals is associated with a respective access level that satisfies an access level criterion that is associated with the respective ER session, such as is managed by the privacy subsystem  170  in  FIG.  1   . Accordingly, for example, a particular individual who has no preexisting relationship with any of the individuals currently associated with an ER environment cannot view a corresponding diorama-view representation. 
     As represented by block  312 , in some implementations, at least a subset of the plurality of diorama-view representations includes one or more ER representations (e.g., avatars) of one or more corresponding individuals. Each of the one or more corresponding individuals is associated with a respective ER session. As one example, with reference to  FIG.  2 A , the electronic device  203  displays an avatar  236  that is associated with an ER session, which, itself, is associated with the first ER environment. In some implementations, the method  300  includes providing two-way audio between an electronic device and an avatar within a diorama-view representation. To that end, the method  300  includes playing, via a speaker of the electronic device, a first set of speech data while displaying the plurality of diorama-view representations. The first set of speech data is associated with one or more corresponding individuals that are associated with a particular ER session associated with a respective ER environment. For example, the first set of speech data is uttered by the one or more corresponding individuals. As another example, the playback of the first set of speech data is in real time or is delayed via buffering. As yet another example, the first set of speech data may be spatialized so as to sound as though originating from within a diorama-view representation. Moreover, the method  300  includes obtaining, via an audio sensor of the electronic device, a second set of speech data from a user associated with the electronic device. Moreover, the method  300  includes providing the second set of speech data to the respective ER environment so that the second set of speech data is audible to the one or more corresponding individuals that are associated with the particular ER session. The second set of speech data may be presented to participants of respective ER environments in a variety of ways, such as spatialized audio from above the respective ER environments. 
     As represented by block  314 , in some implementations, the first one of the plurality of diorama-view representations corresponds to an augmented reality (AR) representation of a first ER environment. For example, the first one of the plurality of diorama-view representations includes AR content overlaid on environmental data that is associated with physical features of an operating environment. For example, with reference to  FIG.  2 A , the couch  238  within the first diorama-view representation  230  may correspond to a physical couch that is associated with the first ER environment. In some implementations, the method  300  includes obtaining (e.g., via an image sensor) the environmental data (e.g., pass-through image data), generating ER objects, and overlaying the ER objects on the environmental data. 
     As represented by block  316 , in some implementations, the first one of the plurality of diorama-view representations corresponds to a virtual reality (VR) representation of a first ER environment. For example, the second diorama-view representation  240 , including structural objects (e.g., the floor and walls), the credenza  244 , and the chair  246  correspond to ER objects. 
     As represented by block  318 , the method  300  includes detecting, via one or more input devices, an input associated with the first one of the plurality of diorama-view representations. As represented by block  320 , in some implementations, the input is directed to the first one of the plurality of diorama-view representations. As one example, with reference to  FIG.  2 H , the manipulation input  253  is directed to the first diorama-view representation  230 . For example, the input changes the orientation of (e.g., rotating) the first one of the plurality of diorama-view representations. As another example, the input moves the first one of the plurality of diorama-view representations along an axis, such as translating the first one of the plurality of diorama-view representations along an x-y axis. 
     As represented by block  322 , in some implementations, the input corresponds to a change in position of the electronic device from a first pose to a second pose relative to the first one of the plurality of diorama-view representations. As represented by block  324 , in some implementations, the input is directed to multiple diorama-view representations. For example, the electronic device includes an IMU that detects positional changes of the electronic device. As one example, with reference to  FIG.  2 D , the electronic device  203  detects the movement input  251  that corresponds to the user  210  moving around the first diorama-view representation  230  and the second diorama-view representation  240  within the operating environment  200 . In response to detecting the movement input  251 , the electronic device  203  changes the first diorama-view representation  230  and the second diorama-view representation  240  from a first pose to a second pose. 
     As represented by block  326 , the method  300  includes, in response to detecting the input, changing display of the first one of the plurality of diorama-view representations from the first viewing vector to a second viewing vector while maintaining the first one or more ER objects arranged according to the first set of ER world coordinates. As one example, with reference to  FIGS.  2 D and  2 E , in response to detecting the movement input  251 , the electronic device  203  correspondingly changes respective viewing vectors associated with the first diorama-view representation  230  and the second diorama-view representation  240 , as indicated by respective changes to the first ER world coordinates  232  and the second ER world coordinates  242 . As another example, with reference to  FIGS.  2 H and  2 I , in response to detecting the manipulation input  253  directed to the first diorama-view representation  230 , the electronic device  203  correspondingly rotates the first diorama-view representation  230 , as indicated by a change to the first ER world coordinates  232  relative to the home ER world coordinates  208 . 
       FIG.  4    is a flow diagram of a method  400  of transforming a spatial relationship between a subset of ER objects as a function of respective coordinates associated with a corresponding diorama-view representation and home ER world coordinates in accordance with some implementations. In various implementations, the method  400  or portions thereof are performed by an electronic device (e.g., the electronic device  100  in  FIG.  1    or the electronic device  203  in  FIGS.  2 A- 2 V ). In various implementations, the method  400  or portions thereof are performed by an HMD. In some implementations, the method  400  is performed by processing logic, including hardware, firmware, software, or a combination thereof. In some implementations, the method  400  is performed by a processor executing code stored in a non-transitory computer-readable medium (e.g., a memory). In various implementations, some operations in method  400  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As represented by block  402 , in some implementations, the method  400  includes displaying a plurality of diorama-view representations of a corresponding plurality of ER environments within a home ER environment. The plurality of diorama-view representations includes a first diorama-view representation of a first ER environment. As one example, with reference to  FIG.  2 A , the electronic device  203  displays a first diorama-view representation  230  of a first ER environment and a second diorama-view representation  240  of a second ER environment within the home ER environment  206 . Continuing with this example, the first diorama-view representation  230  includes a television  234 , an avatar  236 , and a couch  238  arranged according to first ER world coordinates  232 . Continuing with this example, the second diorama-view representation  240  includes a credenza  244  and a chair  246  arranged according to second ER world coordinates  242 . 
     In some implementations, as represented by block  404 , the method  400  includes detecting a selection input that selects the first diorama-view representation from the plurality of diorama-view representations. As one example, with reference to  FIG.  2 F , the electronic device  203  detects the selection input  252  that is directed to the first diorama-view representation  230 . In some implementations, as represented by block  406 , the select input is based on eye gaze data obtained by, for example, an eye tracking sensor integrated within an electronic device or HMD. For example, the eye gaze data indicates that an eye gaze location of a user is directed to the first diorama-view representation of the plurality of diorama-view representations. 
     As represented by block  408 , the method  400  includes displaying a home ER environment characterized by home ER world coordinates, including the first diorama-view representation of the first ER environment. The first diorama-view representation includes one or more of ER objects arranged in a spatial relationship according to first ER world coordinates. In some implementations, displaying the first diorama-view representation includes ceasing to display the remainder of the plurality of diorama-view representations. In some implementations, displaying the first diorama-view representation includes displaying the remainder of the plurality of diorama-view representations with a lower resolution than the first diorama-view representation. In some implementations, displaying the first diorama-view representation includes ceasing to perform live updates of contents of the first diorama-view representation. In some implementations, the first diorama-view representation corresponds to a reduced-size representation of the first ER environment. As an example, the one or more ER objects includes a combination of movable objects (e.g., a chair or table), living objects (e.g., one or more avatars representing respective individuals), structural objects (e.g., ceiling, wall, boundary of the diorama-view representation), anchored objects (e.g., a bookshelf), and/or the like. The orientation, position, location, etc. of the one or more ER objects is based on the first ER world coordinates. In some implementations, as represented by block  410 , the home ER environment includes one or more physical objects associated with the home ER world coordinates. As one example, with reference to  FIG.  2 A , the home ER environment  206  includes a physical table  220 . 
     As represented by block  412 , the method  400  includes detecting a first input that is directed to the first diorama-view representation. As one example, with reference to  FIG.  2 N , the acceptance input  259  accepts an invitation to join an ER session associated with the first diorama-view representation  230 . For example, the first input is associated with an interest to initiate (e.g., join or display) the first ER environment, such as a voice input, picking up or putting down the first diorama-view representation (e.g., as detected via a hand sensor), etc. 
     As represented by block  414 , the method  400  includes, in response to detecting the first input, transforming the home ER environment. According to some implementations, transforming the home ER environment includes ceasing to display the first diorama-view representation within the home ER environment and transforming the spatial relationship between a subset of the one or more ER objects as a function of the home ER world coordinates and the first ER world coordinates. As represented by block  416 , the method  400  includes displaying the subset of the one or more ER objects within the home ER environment based on the transformation. As one example, in response to detecting the acceptance input  259  that selects the first diorama-view representation  230  in  FIG.  2 N , the electronic device  203  displays the bounded ER environment  261  including the transformed television  264 , the transformed avatar  266 , and the transformed couch  268 , as illustrated in  FIG.  2 O . For example, the subset of the one or more ER objects corresponds to respective representations of the corresponding ER objects. As another example, the subset of the one or more ER objects may include some or all of the one or more ER objects. In some implementations, transforming the spatial relationship includes increasing respective sizes of the subset of the one or more ER objects as compared with the same objects within the first diorama-view representation. In some implementations, transforming the spatial relationship includes increasing distances between the subset of the one or more ER objects as compared with the same objects within the first diorama-view representation, while maintaining relative distances between the subset of the one or more ER objects. For example, in the first diorama-view representation an ER stapler is 1 inch from an ER table and 3 inches from an ER wall and the transformation changes the distance between the ER stapler and the ER table to 2 inches and the distance between the ER stapler and the ER wall to 6 inches. In some implementations, transforming the spatial relationship includes moving the subset of the one or more ER objects relative to the home ER environment, such as dragging the subset of the one or more ER objects along an x-y axis. In some implementations, transforming the spatial relationship includes continuously increasing respective sizes of the subset of the one or more ER objects until true-scale representations of the subset of the one or more ER objects are achieved. 
     In some implementations, as represented by block  418 , the method  400  includes, in response to detecting the first input, displaying the subset of the one or more ER objects from a first viewing vector. For example, the viewing vector provides one or more of: a field-of-view (FOV), pose/rotational coordinates, translational coordinates, a perspective, and/or the like. 
     In some implementations, as represented by block  420 , the method  400  includes moving the subset of the one or more ER objects based on identified physical object(s). To that end, the method  400  includes obtaining, via an image sensor, environmental data (e.g., pass-through image data) bounded by a field-of-view associated with the image sensor, wherein the environmental data is associated with a physical environment including one or more physical objects. Moreover, the method  400  includes identifying, within the environmental data, a particular one of the one or more physical objects located within a spatial proximity threshold of the subset of the one or more ER objects and moving the subset of the one or more ER objects relative to the one or more physical objects based on the particular one of the one or more physical objects. For example, the method  400  includes identifying the particular one of the one or more physical objects via instance segmentation and/or semantic segmentation. As another example, the particular one of the one or more physical objects is larger than a volumetric threshold and thus is likely to obscure the subset of the one or more ER objects. In some implementations, the particular one of the one or more physical objects satisfies a spatial proximity threshold with respect to the subset of the one or more ER objects. For example, the spatial proximity threshold is satisfied when the particular one of the one or more physical objects is less than a threshold distance away from the subset of the one or more ER objects. In some implementations, the method  400  includes displaying an indicator that is indicative of the particular one of the one or more physical objects, such as a color overlay or animation that is on the surface of a portion of the particular one of the one or more physical objects (e.g., “do not move the ER environment downwards because there is a large wall there”). 
     In some implementations, as represented by block  422 , the method  400  includes detecting a second input. As one example, the second input is directed to the subset of the one or more ER objects. For example, the second input is directed to a separate affordance, such as pressing a left arrow in order to move a diorama-view representation leftwards. In some implementations, the second input has three degrees of freedom. For example, a diorama-view representation may be spun, rotated, and/or translated along an x-z plane, but not moved up or down in a y direction. In some implementations, the second input is detected via an inertial measurement unit (IMU), such as a gyroscope or accelerometer. As another example, the second input corresponds to a change in position of the electronic device from a first pose to a second pose relative to the subset of the one or more ER objects. 
     In some implementations, as represented by block  424 , the second input is detected via a hand tracking sensor or an eye tracking sensor. To that end, in some implementations, the method  400  includes detecting the second input via the hand tracking sensor; obtaining hand tracking data from the hand tracking sensor based on the second input; and determining, from the hand tracking data, that the second input is directed to the subset of the one or more ER objects. For example, the method  400  includes comparing a hand position indicated by the hand tracking data against the position of the subset of the one or more ER objects. In some implementations, the method  400  includes detecting the second input via the eye tracking sensor; obtaining eye tracking data from the eye tracking sensor based on the second input; and determining, from the eye tracking data, that the second input is directed to the subset of the one or more ER objects. For example, the method  400  includes determining the second input is directed to the subset of the one or more ER objects by comparing an eye gaze position indicated by the eye gaze data against the position of the subset of the one or more ER objects. 
     In some implementations, as represented by block  426 , the method  400  includes, in response to detecting the second input, changing display of the subset of the one or more ER objects from the first viewing vector to a second viewing vector while maintaining the subset of the one or more ER objects arranged according to the first ER world coordinates. For example, changing display of the subset of the one or more ER objects from the first viewing vector to a second viewing vector may include a combination of rotating, flipping, or moving along a fixed axis with a nominal amount of rotation, etc. As one example, in response to detecting the input  272  in  FIG.  2 R , the electronic device  203  moves the transformed television  264 , the transformed avatar  266 , and the transformed couch  268  from above the physical table  220  downwards along the z-axis of the home ER world coordinates  208  to the side of the physical table  220  in  FIG.  2 S . Continuing with this example, the electronic device  203  maintains arrangement of the transformed television  264 , the transformed avatar  266 , and the transformed couch  268  according to the transformed ER world coordinates  262 . In some implementations, as represented by block  428 , changing display of the subset of the one or more ER objects from the first viewing vector to the second viewing vector is based on the change in position of the electronic device from a first pose to a second pose. In some implementations, as represented by block  430 , changing display of the subset of the one or more ER objects from the first viewing vector to the second viewing vector includes moving the subset of the one or more ER objects relative to the one or more physical objects. 
     In some implementations, as represented by block  432 , the method  400  includes detecting an input requesting to enter the first ER environment. As one example, with reference to  FIG.  2 T , the input  274  is directed to the bounded ER environment  261  and corresponds to a request to enter the bounded ER environment  261 . For example, the input  274  corresponds to one of an eye gaze input, a hand gesture, a voice input, a touch input, and/or the like. As another example, the input  274  corresponds to placing or dropping a diorama-view representation on the ground in order to enable the diorama-view representation expand to true-scale or in order to enable the diorama-view representation replace the current environment. 
     In some implementations, as represented by block  434 , the method  400  includes, in response to detecting the input requesting to enter the first ER environment, adding the subset of the one or more ER objects to the home ER environment. As one example, in response to detecting the input  274  in  FIG.  2 T , the electronic device  203  adds the transformed television  264 , the transformed avatar  266 , and the transformed couch  268  to the home ER environment  206  including the physical table  220 , as illustrated in  FIG.  2 U . In some implementations, adding the subset of the one or more ER objects to the home ER environment includes overlaying the subset of the one or more ER objects on physical objects within the home ER environment. In some implementations, adding the subset of the one or more ER objects to the home ER environment includes skinning physical features (e.g., structural features, such as walls, floor) of the first ER environment and adding the physical features, in addition to adding the subset of the one or more ER objects, to the home ER environment. 
     In some implementations, as represented by block  436 , the method  400  includes, in response to detecting the input requesting to enter the first ER environment, replacing the home ER environment with the first ER environment that includes the subset of the one or more ER objects. For example, replacing the home ER environment with the first ER environment corresponds to replacing the home ER environment with a purely VR environment. As one example, in response to detecting the input  274  in  FIG.  2 T , the electronic device  203  replaces the home ER environment  206  with the first ER environment  290 , as illustrated in  FIG.  2 V . As contrasted with the home ER environment  206  illustrated in  FIG.  2 U , the first ER environment  290  corresponds to a purely VR environment and thus does not include the physical table  220 .
