     FIELD 
     The present disclosure relates generally to computer-generated reality environments, and more specifically to dynamically controlling displays in a computer-generated reality environment. 
     BACKGROUND 
     Computer-generated reality environments are environments where at least some objects displayed for a user&#39;s viewing are generated by a computer. In some uses, a user may interact with a representation of a physical display within the computer-generated reality environment. However, there is a lack of robust functionality for dynamically controlling the size of displays within computer-generated reality environments. In addition, there is a lack of functionality for controlling the display of representations within computer-generated reality environments. 
     Furthermore, in current systems, there is a lack of functionality for controlling a display of user interface elements based on a gaze within computer-generated reality environments. Further still, existing systems lack functionality for controlling the displaying of a virtual display window based on a hinge angle of a physical device within computer-generated reality environments.

     DESCRIPTION 
     Various examples of electronic systems and techniques for using such systems in relation to various CGR technologies are described. 
     A physical environment (or real environment) refers to a physical world that people can sense and/or interact with without aid of electronic systems. Physical environments, such as a physical park, include physical articles (or physical objects or real objects), such as physical trees, physical buildings, and physical people. People can directly sense and/or interact with the physical environment, such as through sight, touch, hearing, taste, and smell. 
     In contrast, a CGR environment refers to a wholly or partially simulated environment that people sense and/or interact with via an electronic system. In CGR, a subset of a person&#39;s physical motions, or representations thereof, are tracked, and, in response, one or more characteristics of one or more virtual objects simulated in the CGR environment are adjusted in a manner that comports with at least one law of physics. For example, a CGR system may detect a person&#39;s head turning and, in response, adjust graphical content and an acoustic field presented to the person in a manner similar to how such views and sounds would change in a physical environment. In some situations (e.g., for accessibility reasons), adjustments to characteristic(s) of virtual object(s) in a CGR environment may be made in response to representations of physical motions (e.g., vocal commands). 
     A person may sense and/or interact with a CGR object using any one of their senses, including sight, sound, touch, taste, and smell. For example, a person may sense and/or interact with audio objects that create a 3D or spatial audio environment that provides the perception of point audio sources in 3D space. In another example, audio objects may enable audio transparency, which selectively incorporates ambient sounds from the physical environment with or without computer-generated audio. In some CGR environments, a person may sense and/or interact only with audio objects. 
     Examples of CGR include virtual reality and mixed reality. 
     A virtual reality (VR) environment (or virtual environment) refers to a simulated environment that is designed to be based entirely on computer-generated sensory inputs for one or more senses. A VR environment comprises a plurality of virtual objects with which a person may sense and/or interact. For example, computer-generated imagery of trees, buildings, and avatars representing people are examples of virtual objects. A person may sense and/or interact with virtual objects in the VR environment through a simulation of the person&#39;s presence within the computer-generated environment, and/or through a simulation of a subset of the person&#39;s physical movements within the computer-generated environment. 
     In contrast to a VR environment, which is designed to be based entirely on computer-generated sensory inputs, a mixed reality (MR) environment refers to a simulated environment that is designed to incorporate sensory inputs from the physical environment, or a representation thereof, in addition to including computer-generated sensory inputs (e.g., virtual objects). On a virtuality continuum, an MR environment is anywhere between, but not including, a wholly physical environment at one end and a VR environment at the other end. 
     In some MR environments, computer-generated sensory inputs may respond to changes in sensory inputs from the physical environment. Also, some electronic systems for presenting an MR environment may track location and/or orientation with respect to the physical environment to enable virtual objects to interact with real objects (that is, physical articles from the physical environment or representations thereof). For example, a system may account for movements so that a virtual tree appears stationary with respect to the physical ground. 
     Examples of MR include augmented reality and augmented virtuality. 
     An augmented reality (AR) environment refers to a simulated environment in which one or more virtual objects are superimposed over a physical environment, or a representation thereof. For example, an electronic system for presenting an AR environment may have a transparent or translucent display through which a person may directly view the physical environment. The system may be configured to present virtual objects on the transparent or translucent display, so that a person, using the system, perceives the virtual objects superimposed over the physical environment. Alternatively, a system may have an opaque display and one or more imaging sensors that capture images or video of the physical environment, which are representations of the physical environment. The system composites the images or video with virtual objects, and presents the composition on the opaque display. A person, using the system, indirectly views the physical environment by way of the images or video of the physical environment, and perceives the virtual objects superimposed over the physical environment. As used herein, a video of the physical environment shown on an opaque display is called “pass-through video,” meaning a system uses one or more image sensor(s) to capture images of the physical environment, and uses those images in presenting the AR environment on the opaque display. Further alternatively, a system may have a projection system that projects virtual objects into the physical environment, for example, as a hologram or on a physical surface, so that a person, using the system, perceives the virtual objects superimposed over the physical environment. 
     An AR environment also refers to a simulated environment in which a representation of a physical environment is transformed by computer-generated sensory information. For example, in providing pass-through video, a system may transform one or more sensor images to impose a select perspective (e.g., viewpoint) different than the perspective captured by the imaging sensors. As another example, a representation of a physical environment may be transformed by graphically modifying (e.g., enlarging) portions thereof, such that the modified portion may be representative but not photorealistic versions of the originally captured images. As a further example, a representation of a physical environment may be transformed by graphically eliminating or obfuscating portions thereof. 
     An augmented virtuality (AV) environment refers to a simulated environment in which a virtual or computer generated environment incorporates one or more sensory inputs from the physical environment. The sensory inputs may be representations of one or more characteristics of the physical environment. For example, an AV park may have virtual trees and virtual buildings, but people with faces photorealistically reproduced from images taken of physical people. As another example, a virtual object may adopt a shape or color of a physical article imaged by one or more imaging sensors. As a further example, a virtual object may adopt shadows consistent with the position of the sun in the physical environment. 
     There are many different types of electronic systems that enable a person to sense and/or interact with various CGR environments. Examples include head mounted systems, projection-based systems, heads-up displays (HUDs), vehicle windshields having integrated display capability, windows having integrated display capability, displays formed as lenses designed to be placed on a person&#39;s eyes (e.g., similar to contact lenses), headphones/earphones, speaker arrays, input systems (e.g., wearable or handheld controllers with or without haptic feedback), smartphones, tablets, and desktop/laptop computers. A head mounted system may have one or more speaker(s) and an integrated opaque display. Alternatively, a head mounted system may be configured to accept an external opaque display (e.g., a smartphone). The head mounted system may incorporate one or more imaging sensors to capture images or video of the physical environment, and/or one or more microphones to capture audio of the physical environment. Rather than an opaque display, a head mounted system may have a transparent or translucent display. The transparent or translucent display may have a medium through which light representative of images is directed to a person&#39;s eyes. The display may utilize digital light projection, OLEDs, LEDs, uLEDs, liquid crystal on silicon, laser scanning light source, or any combination of these technologies. The medium may be an optical waveguide, a hologram medium, an optical combiner, an optical reflector, or any combination thereof. In one example, the transparent or translucent display may be configured to become opaque selectively. Projection-based systems may employ retinal projection technology that projects graphical images onto a person&#39;s retina. Projection systems also may be configured to project virtual objects into the physical environment, for example, as a hologram or on a physical surface.

Processor(s)  102  include one or more general processors, one or more graphics processors, and/or one or more digital signal processors. In some examples, memory(ies)  106  are one or more non-transitory computer-readable storage mediums (e.g., flash memory, random access memory) that store computer-readable instructions configured to be executed by processor(s)  102  to perform the techniques described below. 
     System  100  includes RF circuitry(ies)  104 .

     System  100  includes display(s)  120 . In some examples, display(s)  120  include a first display (e.g., a left eye display panel) and a second display (e.g., a right eye display panel), each display for displaying images to a respective eye of the user. Corresponding images are simultaneously displayed on the first display and the second display. Optionally, the corresponding images include the same virtual objects and/or representations of the same physical objects from different viewpoints, resulting in a parallax effect that provides a user with the illusion of depth of the objects on the displays. In some examples, display(s)  120  include a single display. Corresponding images are simultaneously displayed on a first area and a second area of the single display for each eye of the user. Optionally, the corresponding images include the same virtual objects and/or representations of the same physical objects from different viewpoints, resulting in a parallax effect that provides a user with the illusion of depth of the objects on the single display. 
     In some examples, system  100  includes touch-sensitive surface(s)  122  for receiving user inputs, such as tap inputs and swipe inputs. In some examples, display(s)  120  and touch-sensitive surface(s)  122  form touch-sensitive display(s). 
     System  100  includes image sensor(s)  108 . Image sensors(s)  108  optionally include one or more visible light image sensor, such as charged coupled device (CCD) sensors, and/or complementary metal-oxide-semiconductor (CMOS) sensors operable to obtain images of physical objects from the real environment. Image sensor(s) also optionally include one or more infrared (IR) sensor(s), such as a passive IR sensor or an active IR sensor, for detecting infrared light from the real environment. For example, an active IR sensor includes an IR emitter, such as an IR dot emitter, for emitting infrared light into the real environment. Image sensor(s)  108  also optionally include one or more event camera(s) configured to capture movement of physical objects in the real environment. Image sensor(s)  108  also optionally include one or more depth sensor(s) configured to detect the distance of physical objects from system  100 . In some examples, system  100  uses CCD sensors, event cameras, and depth sensors in combination to detect the physical environment around system  100 . In some examples, image sensor(s)  108  include a first image sensor and a second image sensor. The first image sensor and the second image sensor are optionally configured to capture images of physical objects in the real environment from two distinct perspectives. In some examples, system  100  uses image sensor(s)  108  to receive user inputs, such as hand gestures. In some examples, system  100  uses image sensor(s)  108  to detect the position and orientation of system  100  and/or display(s)  120  in the real environment. For example, system  100  uses image sensor(s)  108  to track the position and orientation of display(s)  120  relative to one or more fixed objects in the real environment. 
     In some examples, system  100  includes microphones(s)  112 . System  100  uses microphone(s)  112  to detect sound from the user and/or the real environment of the user.

Orientation sensor(s)  110  optionally include one or more gyroscopes and/or one or more accelerometers. 
     Various aspects of the present disclosure are directed to systems and techniques that provide functionality for controlling displays (e.g., virtual displays) within a CGR environment. 
     In particular, aspects of the present disclosure are directed to systems and techniques that provide functionality to dynamically control the size of a display in a CGR environment. In some aspects, controlling the size of a display may include controlling a resizing of the display. The systems and techniques described herein allow for expanding and/or contracting a representation of a display in a CGR environment, for example in response to a moving of a visual object meeting a resizing criterion. Throughout this disclosure, resizing may be used to refer collectively to the expansion and/or contraction of the representation of a display within a CGR. As shown in embodiments described below, expansion of the representation of a display may be performed virtually, in which the expanded representation of the display may include at least an area or portion that is a computer-generated display area. As also shown in embodiments described below, contraction of the representation of a display may be performed virtually, in which contracting the representation of a display may include ceasing to display at least an area or portion of a computer-generated display area (e.g., a portion of the expanded display area) and/or obfuscating a portion of the representation of the display (e.g., obfuscating a portion of a physical display within the CGR environment). 
       FIGS.  2 A- 2 F  illustrate exemplary techniques for dynamically controlling the size of a display in a CGR environment in accordance with aspects of the present disclosure. In particular,  FIG.  2 A  illustrates user  202  and electronic device  200 . In some embodiments, electronic device  200  may be a wearable electronic device (e.g., an HMD). Examples of a wearable electronic device are described herein, such as with respect to electronic device  100   a  described above with reference to  FIGS.  1 A and  1 B . 
     It is noted that although the discussion that follows is focused on a wearable electronic device, such as an HMD, this is done by way of example and should not be construed as limiting in any way. Indeed, the techniques disclosed herein may be applicable to any implementation and form factor of electronic devices configured to present a CGR environment (e.g., HMDs, HUDs, vehicle windshields having integrated display capability, windows having integrated display capability, etc.) as described above. 
     In embodiments, electronic device  200  may be configured to present a CGR environment to user  202 . The CGR environment presented to user  202  may include presenting display  204 . In aspects, display  204  may be a representation of a physical display (e.g., a monitor or screen of a physical computer). For example, display  204  may be a computer-generated simulation of a physical display. In some embodiments, the computer-generated simulation of a physical display may be configured to be perceived as a physical display by user  202 , although display  204  may be a computer-generated simulation of a physical display, and/or may be configured to behave as a physical display. In some embodiments, the computer-generated simulation of a physical display may be a computer-generated display area with no corresponding physical counterpart and/or representation. In these cases, the computer-generated simulation of a physical display may be a display area that may not simulate a physical display. In these embodiments, the computer-generated simulation of a physical display may not be configured to be perceived as a physical display by user  202 , but instead may be configured to be perceived as a virtual display area, and/or may not be configured to behave as a physical display. 
     In some embodiments, display  204  may represent a physical display that is presented to user  202  via electronic device  200 . For example, display  204  may include an actual physical display, and may not be a computer-generated simulation of the display. In this case, display  204  may be presented to user  202  such that user  202  may view the physical display, instead of viewing a computer-generated simulation of the physical display. In some embodiments, presenting the physical display to user  202  may be performed via a transparent or translucent display of electronic device  200 , or may be performed via pass-through video as described above, such that user  202  may perceive the actual physical display. In yet other embodiments, presenting the physical display to user  202  may be performed by superimposing a photorealistic image and/or video of the physical display on a simulated environment. 
     In other embodiments, display  204  may include a computer-generated simulation of a physical display (e.g., a computer-generated simulation of a physical display or a purely virtual display) as described above. The computer-generated simulation of the physical display may be presented to the user  202  via electronic device  200 . In some embodiments, presenting the computer-generated simulation of the physical display to user  202  may include displaying the computer-generated simulation of the physical display on a display of electronic device  200 . In some implementations, the computer-generated simulation of the physical display may be superimposed upon a physical environment, or a representation thereof (e.g., as in MR implementations), such that user  202  may perceive the computer-generated simulation of the physical display superimposed over the physical environment. In other implementations, the computer-generated simulation of the physical display may be a virtual object that is part of a fully CGR environment (e.g., as in VR applications). 
     It is noted that display  204 , whether a representation of a physical display or a computer-generated simulation, may be presented as a 3D object. As such, user  202  may perceive display  204  as a 3D representation of a physical display. In some embodiments, where display  204  is a computer-generated simulation of a physical display, display  204  may be presented to the user with a blurred background, and/or a translucent background, such that objects behind display  204  may be visible, or at least somewhat visible, to user  202 . In the case where display  204  is a physical display, display  204  may be presented to user  202  without a blurred or translucent background, such that objects behind display  204  may not be visible to user  202 . 
     In embodiments, display  204  may be represented as having a particular size. For example, where display  204  is an actual physical display, the size of display  204  may be determined by the actual size of the display. In implementations where display  204  is a computer-generated simulation, the size of the simulated display may be predetermined and may be perceived by user  202 . It is noted that in a computer-generated simulation, the size of display  204  may be a size as perceived by the user in the CGR environment. In these cases, user  202  may perceive display  204  to be a particular size as determined by operations and functionality of electronic device  200 . 
     In some embodiments, display  204  may include display area  206 . Display area  206  may be configured to function as the display area of display  204  such that visual objects (e.g., visual object  210 ) to be displayed by display  204  may be presented on display area  206 . In embodiments, display area  206  may have a particular size, which may comprise a portion or the entirety of display  204 . In some embodiments, display area  206  may comprise the entirety of display  204  such that display area  206  encompasses the area from edge to edge of display  204 . In other embodiments, display  204  may include bezel  208  of a particular width that surrounds display  204 . In this case, display area  206  may encompass the area of display  204  not including bezel  208 . 
     Visual object  210  may be a visual object configured to be displayed on display  204 . In some aspects, visual object  210  may be a 2D object and may be any visual object that may be configured to be displayed on a display. For example, visual object  210  may be an icon, a 2D window, an image, etc. 
     In some embodiments, such as in implementations where display  204  may be a physical display, visual object  210  may be an object displayed on the physical display. For example, visual object  210  may be displayed as a graphical object of display  204 . In these cases, visual object  210  may be presented to user  202  via a transparent or translucent display of electronic device  200 , or via pass-through video, such that user  202  may perceive the graphical object displayed on display  204 . 
     In other embodiments, visual object  210  may be a visual object displayed on a display of electronic device  200 . In some implementations, the visual object displayed on electronic device  200  may be superimposed on the representation of display  204 . Where display  204  is a physical display, user  202  may perceive the visual object as being displayed on display  204 , although visual object  204  may not be displayed on display  204  but rather on a display of electronic device  200 . Where display  204  is a computer-generated simulation of a physical display, user  202  may perceive the visual object as being displayed on display  204 , where both visual object  204  and display  204  may be displayed on a display of electronic device  200 . 
     Display  204  may also be configured to include a proximity threshold  212 . In embodiments, proximity threshold  212  may be visible or may be invisible on display  204 . Proximity threshold  212  may be predetermined to be a particular distance  214  from an edge of display area  206 , or from an edge of display  204 . As a traditional display may have four edges, in some embodiments, a proximity threshold may be configured for each of the edges or for any subset of the four edges. For example, a proximity threshold may be configured for the right and left edges of display  204 , but no proximity threshold may be configured for the top and bottom edges of display  204 . As will be described in more detail below, proximity threshold  212  may be used to determine whether display  204  may be resized in accordance with aspects of the present disclosure. It is noted that in some implementation, display  204  does not include a proximity threshold for any of the edges. 
       FIG.  2 B  illustrates an example of visual object  210  being moved in direction  216  from first location  220  to second location  222  of display area  206 . In aspects, the moving of visual object  210  from first location  220  to second location  222  may be in response to a request to move visual object  210 . The request to move visual object  210  may be included in a user input. For example, a user (e.g., user  202 , or another user) may drag or otherwise move visual object  210  from first location  220  to second location  222 . The dragging or moving of visual object  210  may be performed using input sensors, as described above, configured to detect a user input to interact with visual objects of the CGR environment. In some embodiments, the input sensors may include a mouse, a stylus, touch-sensitive surfaces, image-sensors, etc. 
     As illustrated in  FIG.  2 B , the moving operation of visual object  210  in direction  216  from first location  220  to second location  222  may not meet a criterion for resizing display  204 . In embodiments, the criterion for resizing display  204  may include any one or more of the second location being within a proximity threshold of an edge of the display, the second location being at least partially outside of the display area of the display, and/or the moving operation being in a particular direction. When the moving operation of visual object  210  meets any of the above criteria, display  204  may be resized in accordance with aspects of the present disclosure. However, when the moving operation of visual object  210  does not meet any of the above criteria, resizing of display  204  may be forgone. 
     As used herein, a second location being within a proximity threshold of an edge of the display may include the situation where the visual object being moved to the second location at least partially enters the proximity threshold when in the second location. Similarly, the second location being at least partially outside of the display area of the display may include the situation where the visual object being moved to the second location at least partially enters the area outside the display area of the display when in the second location. 
     For example, as illustrated in  FIG.  2 B , second location  222  may be within display area  206 . However, in this case, second location  222  may not be within a predetermined proximity (e.g., proximity threshold  212 ) to the edge of display  204 , or at least partially outside display area  206 . As such, in the example illustrated in  FIG.  2 B , display  204  may not be resized. In some embodiments, the criterion for resizing the display is not met until the entire visual object being moved enters the proximity threshold or the area outside the display area. 
       FIG.  2 C  illustrates another example of a moving operation of visual object  210  in direction  216  from first location  220  to second location  224 . As shown in  FIG.  2 C , a request to move visual object  210  from first location  220  to second location  224  may be received. Second location  224  is a location in which at least a portion of visual object  210  is within proximity threshold  212  to edge  230  of display  204 . In this case, second location  224  being a location in which at least a portion of visual object  210  is within proximity threshold  212  to edge  230  of display  204  meets a criterion for resizing display  204 . In response to the second location meeting a criterion for resizing the display, display  204  may be resized. 
       FIG.  2 D  illustrates yet another example of a moving operation of visual object  210  in direction  216  from first location  220  to second location  226 . As shown in  FIG.  2 D , a request to move visual object  210  from first location  220  to second location  226  may be received. Second location  226  is a location in which at least a portion of visual object  210  is outside the display area of display  204 . In this case, second location  226  being a location in which at least a portion of visual object  210  is outside the display area of display  204  meets a criterion for resizing display  204 . In response to the second location meeting a criterion for resizing the display, display  204  may be resized. 
     In embodiments, resizing display  204  may include expanding the display area of display  204  by displaying display area  206  and additional display area  260 . Additional display area  260  may be a computer-generated display area that may be appended or otherwise added to display  204  such that expanded display  204  may be perceived as larger by user  202 . In some embodiments, additional display area  260  may be added to display  204  such that the expanded display  204  may be perceived as a single, cohesive, and integrated display by user  202 . In other words, in these embodiments, user  202  may not perceive that additional display area  260  has been appended to display  204 . In implementations where display  204  is a computer-generated simulation, expanding the display  204  may include displaying display  204  in a larger size, including additional display area  260 . 
     In embodiments, expanding display  204  may include expanding the display in the direction  216  of the moving operation, from the edge  230  of the current display  204  (e.g., the edge of the physical display or the edge of the computer-simulated representation of a physical display) to the edge (e.g., edge  240  in  FIG.  2 C  or edge  242  in  FIG.  2 D ) of the expanded display  204  by an amount  250 . In these embodiments, edge  230  may be determined to be the expanding edge because the request to move the visual object  210  includes a request to move visual object  210  toward edge  230 . 
     The size of the expansion (e.g., the size of additional display area  260 , and/or the size of amount  250 ) may be determined by the size of visual object  210  and may be sized to accommodate displaying visual object  210  in the expanded area. In other embodiments, the size of the expansion may be determined by the amount that the second location (e.g., second location  240  in  FIG.  2 C  or edge  242  in  FIG.  2 D ) and/or the amount that visual object  210  has moved passed proximity threshold  212  toward the edge. For example, where second location  224  and/or visual object  210  have moved x distance passed edge  230 , display  204  may be expanded by an amount x. In yet other embodiments, the size of the expansion may be determined based on ergonomics designs, such as to reduce neck strain. 
     In some embodiments, for example where display  204  is a physical display and visual object  210  is a visual object displayed on display  204 , as visual object  210  enters into the expanded display area of display  204 , visual object  204  may be transitioned to a visual object being displayed on a display of electronic device  200 . In this sense, user  202  is able to perceive visual object  210  even after visual object  210  may be moved to outside the physical display. The transition may also allow for a seamless presentation of visual object  210  as it is moved into the expanded area. 
     It is noted that although the present discussion is focused on an expansion of the display from the left edge of the display leftward, the techniques herein are equally applicable where the expansion may be from the right edge rightward in response to moving a visual object toward the right edge of the display. Additionally, the same applies to an expansion of the top and/or bottom edges. Also, in some embodiments, it is noted that the expansion of the display may be limited to left and right, and moving an object to within a proximity of the top or bottom edges, and/or outside of the area proximate to the top or bottom edges, may not cause an expansion of the display. 
     In embodiments, the expansion of display  204  may be performed as soon as visual object  210  crosses proximity threshold  212  (e.g., as shown in  FIG.  2 C ) or edge  230  (e.g., as shown in  FIG.  2 D ), and display  204  may continue to expand as more of visual object  210  crosses proximity threshold  212  or edge  230 . In other embodiments, display  204  may not be expanded until at least a predetermined portion of visual object  210  has crossed proximity threshold  212  (e.g., as shown in  FIG.  2 C ) or edge  230  (e.g., as shown in  FIG.  2 D ), or until the entirety of visual object  212  has crossed proximity threshold  212  or edge  230 . 
     In some embodiments, expanding display  204  may include animating the expansion operation. For example, with reference to  FIG.  2 D , as display  204  is expanded from current edge  230  to expanded edge  242 , the expansion may be animated by, e.g., displaying the edge of display  204  as moving or shifting from current edge  230  to expanded edge  242 . The speed of the animation may be based on the speed at which visual object  210  is being moved, or may be based on a predetermined and/or fixed value. In some embodiments, as will be described in more detail below, as display  204  is expanded, the expanded display may be curved. 
     In embodiments, resizing operations of display  204  (e.g., expanding and/or contracting) may include rearranging structural elements of display  204 . For example, the representation of display  204  may include display stand  270 . Display stand  270  may be a visual element that provides more realism to the representation of display  204 . In embodiments, resizing display  204  may also include shifting display stand  270  to an appropriate location relative to the expanded display such that the proportions of the display may be maintained. For example, display stand  270  may be shifted from location  272  in the unexpanded display  204  to location  274  in the expanded display  204 . As such, after the expansion operations of display  204 , the stand retains a location approximately in the middle portion of display  204 , thereby maintaining the proportions of a display. In embodiments, the shifting of display stand  270  may be animated and may show the stand sliding from location  272  to location  274  as display  204  is expanded. 
     In some embodiments, the expansion of display  204  may be limited to a particular size. For example, a threshold size may be used whereupon it being reached by the size of expanded display  204 , expansion of display  204  may be forgone. For example, based on moving operations of visual object  210  meeting a resizing criterion (e.g., a criterion for expanding the display), display  204  may be determined to be expanded to a particular size as described above. For example, in order to accommodate visual object  210  in the expanded display, display  204  may be determined to be expanded by amount  250  by adding additional display area  260 , resulting in a target expanded size for the expanded display area of display  204 . Where there is no threshold size, display  204  may be expanded as determined. However, where a threshold size is present, the threshold size may be compared to the target expanded size, and where the target expanded size of display  204  exceeds the threshold size, expansion of display  204  may be forgone. In some embodiments, display  204  may still be expanded, but the expansion may be limited to the threshold size. 
       FIG.  2 E  illustrates another example of a dynamic resizing operation of a display. In the example illustrated in  FIG.  2 E , a request to move visual object  210  from first location  220  to second location  228  may be received. In this example, second location  228  may be a location in which at least a portion of visual object  210  may meet a resizing criterion with respect to more than one edge at the same time. For example, second location  228  may be a location in which at least a portion of visual object  210  is outside the display area proximate to both the left edge and the top edge of display  204 . In this case, display  204  may be expanded from both the left edge  230  and top edge  232  in accordance with the description above. The expansion of the left edge  230  may be to edge  244  and may comprise animating the expansion. Similarly, the expansion of the top edge  232  may be to edge  246  and may comprise animating the expansion. In aspects, the expansion of both left edge  230  and top edge  232  may be done simultaneously or near-simultaneously, and user  202  may perceive the expansion of the two edges as a diagonal expansion. 
     In some embodiments, not illustrated, user  202  may first move visual object  210  from first location  220  to a second location meeting a resizing criterion with respect to a single display edge (e.g., a second location outside the display area proximate to the left edge of display  204 ) and then move visual object  210  from the second location to a third location meeting a resizing criterion with respect to another display edge (e.g., a third location outside the display area proximate to the top edge of display  204 ). In this case, display  204  may first be expanded from the left edge in response to the moving of visual object  210  to the second location, and then subsequently expand from the top edge in response to the moving of visual object  210  to the third location. Alternatively, display  204  may not first be expanded from the left edge and then subsequently from the top edge when a visual object is moved to the second and third locations, respectively, but instead may be expanded from the left edge and the top edge simultaneously, or near-simultaneously, when the visual object is moved to the third location. In that sense, the second location may be thought of as a transitional location and may not cause resizing operations. In aspects, a transitional location may be determined based on whether the moving operations have stopped for a predetermined amount of time. For example, user  202  may first move visual object  210  to the second location, stop for a time period, and then move the visual object to the third location. In this case, if the time period does not exceed a predetermined threshold, the second location may be determined to be a transitional location and expansion of display  204  based on the second location may be forgone (e.g., expansion from the left edge) even if the second location otherwise meets a resizing criterion (e.g., it&#39;s a location within a proximity threshold or is a location outside the display area of display  204 ). 
       FIG.  2 F  illustrates an example of a dynamically controlling a resizing operation of a display that includes contracting the display. In the example illustrated in  FIG.  2 F , a request to move visual object  210  in direction  217  from first location  221  to second location  210  may be received. In embodiments, first location  221  may be part of an expanded display area of display  204 . For example, display  204  may have previously been expanded to include additional display area  260  by expanding from edge  234  to edge  248  by an amount  256 . In this case, moving visual object  210  to within display area  206 , which may not include additional display area  260 , may be determined to meet a resizing criterion. In this case, the resizing criterion may include contracting the expanded display back to the original display size by contracting from edge  248  in direction  217  to edge  234 . Edge  234  may be the actual edge of display  204  (e.g., the edge of display  204  prior to the previous expansion). As described above, with respect to expansion operations, contracting operations may include animating the contraction of the edges such that the edge of display  204  appears to move from edge  248  to edge  234 . 
     In some embodiments, moving visual object  210  to a second location beyond the bottom edge of display  204  may cause contracting operations that may minimize display  204  entirely. In this case, minimizing display  204  may include collapsing the entire display into a representation indicating that the display is in a minimized state. User  202  may interact with the minimized representation to cause display  204  to be restored to a previous size. 
     In some embodiments, not illustrated, the second location may not be entirely within display area  206  and may include at least a portion of additional display area  260 . In this case, it may be determined that resizing criterion has been met, and display  204  may be contracted. In this case, display  204  may be contracted but only to a display size that is still able to accommodate displaying visual object  210  within the contracted display area. This partial contraction may be repeated as visual object  210  is moved to a location entirely within display area  206 . 
     In other embodiments, first location  221  may not represent a part of an expanded display area of display  204 , but instead may be part of unexpanded display area  206 . In this example, the original size of display  204  may include additional display area  260  all the way to edge  248 . For this example, the original size of display  204  may include display area  206  and additional display area  260 . In this case, it may be determined that moving visual object  210  to second location  229  may support a smaller display area for display  204  while still accommodating display of visual object  210 . This may be determined to meet a resizing criterion. In this case, the resizing criterion may include contracting the display area of display  204  to a smaller size. The display area of display  204  may be contracted from edge  248  in direction  217  to edge  234 . Edge  248  may be the actual edge of display  204  (e.g., the edge of display  204  prior to the contraction). As described above, with respect to expansion operations, contracting operations may include animating the contraction of the edges such that the edge of display  204  appears to move from edge  248  to edge  234 . 
     In implementations where display  204  is a physical display, contracting a previously unexpanded display may include obfuscating part of the display. For example, additional display area  260  may be obfuscated when contracting display  204  after moving visual object  210  to second location  229  such that the obfuscated parts of display  204  may not function to display visual objects. One application of this functionality may be in AV applications, where the obfuscated portion of the display may be obfuscated by replacing it with appropriate portions of the computer-generated simulation, such that user  202  may perceive display  204  as smaller while being able to perceive virtual objects behind the obfuscated portions of the display area. 
       FIG.  3    illustrates an example of a shifting operation of a display. In this example, moving visual object  210  from first location  223  to second location  225  may meet a resizing criterion as described above with respect to  FIGS.  2 A- 2 F . However, in this example, instead of resizing display  204 , display  204  is instead shifted in the direction of the moving operation. The amount of shifting may be based on the amount of moving after the visual object has been placed on location meeting a resizing criterion per the above discussion. This functionality may be employed by user  202  to move display  204  to another location when manipulating 2D visual objects displayed on display  204 . 
       FIGS.  4 A and  4 B  illustrate an example of resizing operations in accordance with aspects of the present disclosure.  FIG.  4 A  illustrates user  202  and electronic device  200 . As mentioned above, in some embodiments, electronic device  200  may be a wearable electronic device (e.g., an HMD). As also mentioned above, in some embodiments, electronic device  200  may be similar to electronic device  100   a  described above with reference to  FIGS.  1 A and  1 B . 
       FIG.  4 A  illustrates user  202  being presented with a CGR environment that includes display  204 . As described above, display  204  may be a physical display or a computer-generated simulation of a physical display. Display  204  may include visual objects  410  and  411  within display area  206 . Visual objects  410  and  411  and display area  206  may be as described above. In some aspects, display  204  may be presented to user  202  as a curved display or may be presented as a flat display. 
     As described above, moving operations of visual objects  410  and/or  411  may cause dynamic resizing of display  204 . In embodiments, dynamic resizing of display  204  may include expanding of display  204 . For example, a request to move visual object  210  in direction  416  from location  410  to location  422  may be received. Moving visual object  210  in direction  416  from location  410  to location  422  may be determined to meet a resizing (e.g., expanding) criterion, as described herein. In response to moving visual object  210  in direction  416  from location  410  to location  422 , display  204  may be expanded from edge  430  to edge  440  to include additional display area  460 . Additional display area  460  may be a computer-generated virtual display area configured similarly to additional display area  260  described above. Similarly, a request to move visual object  211  in direction  417  from location  411  to location  423  may be received. Moving visual object  211  in direction  417  from location  411  to location  423  may be determined to meet a resizing (e.g., expanding) criterion, as described herein. In response to moving visual object  211  in direction  417  from location  411  to location  423 , display  204  may be expanded from edge  431  to edge  441  to include additional display area  461 . Additional display area  461  may be a computer-generated virtual display area configured similarly to additional display area  260  described above. 
     In embodiments, as display  204  is expanded from edge  430  to edge  440 , and/or from edge  431  to edge  441 , the expanded display areas may be curved, as can be seen in  FIG.  4 A . In some embodiments, before the expansion, display  204  may or may not be curved, but the expanding operations may cause display  204  to be curved regardless. In these cases, after expansion, not only may the additional area  460  be curved, but the original pre-expansion display may also be curved. In this sense, the expanded display is configured to be perceived by user  202  as a single, cohesive, and integrated curved display. In some embodiments, the expanded display may be contracted based on moving operations of visual object  410 , as described above. In this case, whether the original pre-expansion display  204  was curved or not, after contraction, display  204  may remain curved. In other embodiments, after contraction operations, display  204  may return to a flat configuration. 
       FIG.  4 B  illustrates an example top-view configuration of resizing operations in accordance with aspects of the present disclosure. In particular,  FIG.  4 B  illustrates the curving aspects of expansion operations. For example, as display  204  is expanded in direction  450 , the expanded display is curved. Similarly, as display  204  is expanded in direction  451 , the expanded display is also curved. In some embodiments, the curving of the expanded display may cause the expanded display to partially or fully surround user  202 , such that the user may perceive the display as a display surrounding him or her. In some embodiments, expansion operations in a single direction  452  may continue from one edge of display  204  to the other edge. For example, user  202  may drag a visual object from one location within the display area of display  204  toward edge  432  of display  204  in direction  452 . User  202  may continue to drag the visual object to a location outside of display  204  proximate to edge  432 , causing display  204  to expand from edge  430  in direction  452 . User  202  may continue to drag the visual object in direction  452  through the expansion of display  204 , causing display  204  to continue to be expanded and curved. If user  202  continues to drag the visual object through the expansion until the leading edge  434  of the expansion meets edge  433  of display  204 , the result would be a 360 degree curved expanded display wholly surrounding user  202 , as illustrated in  FIG.  4 B . It is again noted that, as described above, display  204  may be a curved display, even though display  204  is illustrated as a flat display in  FIG.  4 B . 
     In some embodiments, the expanded display area surrounding user  202  may be rotated when user  202  moves his or her head toward the left or the right in order to provide an ergonomically beneficial approach that may reduce neck strain. For example, as user  202  moves his or her head to the right, the expanded display area surrounding user  202  may be rotated toward the left, in order to “bring” the portions of the expanded display area into view of user  202 . In this manner, user  202  does not have to turn his or her neck excessively to view the portions of the expanded display area that are not within the front periphery of user  202 . 
       FIG.  5    is a flow diagram illustrating method  500  for dynamically controlling the size of a display in a CGR environment. In some embodiments, method  500  may be performed by an electronic device such as electronic device  100   a  described above with reference to  FIGS.  1 A and  1 B , and/or electronic device  200 . 
     At block  502 , a representation of a physical display within a CGR environment is presented to a user. For example, an electronic device, such as electronic device  200 , may be used to present a representation of a physical display (e.g., display  204 ) to a user (e.g., user  202 ). In some embodiments, the representation of the display may be an actual physical display presented to the user via a translucent display of the electronic device or pass-through video. In other embodiments, the representation of the display may be a computer-generated simulation of a physical display displayed on a display of the electronic device. In embodiments, the representation of the physical display may include a first display area (e.g., display area  206 ). 
     At block  504 , a visual object (e.g., visual object  210 ) may be displayed at a first location within the first display area of the representation of the physical display. In some embodiments, the visual object may be displayed via the display of the wearable electronic device. In some embodiments, for example, where the representation of the physical display is an actual physical display, the visual object may be displayed on the physical display. In aspects, the visual object may be a 2D object and may be any visual object that may be configured to be displayed on a display. For example, the visual object may be an application icon, a 2D application window, an image, a thumbnail, etc. 
     At block  506 , a request to move the visual object to a second location within the CGR environment may be received. For example, user input may include a request to drag the visual object from the first location to a second location. The user input may include a dragging operation performed using any input sensor configured to operate within a CGR environment, such as a mouse, a stylus, a touch-sensitive surface, image-sensors, etc. 
     At block  508 , in response to receiving the request to move the visual object to the second location, an expanded display area of the representation of the physical display is displayed when the second location meets a criterion. The expanded display area may include at least a portion of the first display area and a second display area. In embodiments, the second display area (e.g., additional display area  260 ) may be a computer-generated display area that may be added to the representation of the physical display to generate the expanded display area. In some embodiments, the second display area may be added to the representation of the physical display such that the expanded display area may be perceived as a single, cohesive, and integrated display by a user. 
     In some embodiments, the criterion that is met by the second location in order to expand the display area may include any one or more of the second location being within a proximity threshold of an edge of the representation of the physical display, the second location being at least partially outside of the first display area, and/or the request to move the visual object being in a particular direction. 
     In embodiments, displaying an expanded display area of the representation of the physical display may include expanding the representation of the physical display in the direction in which the visual object may have been moved. The expanding may include expanding from an edge of the representation of the physical display in the direction of the visual object move. In aspects, the expansion operation may be animated. In some embodiments, when the visual object has been moved to a location meeting a resizing criterion with respect to a top or bottom edge of the representation of the physical display (e.g., the second location is a location within a proximity threshold of a top or bottom edge, or when the second location is a location at least partially outside of the first display area proximate to the top or bottom edge) the displaying of the expanded display area of the representation of the physical display may be forgone. Instead, the size of the representation of the physical display is maintained. 
     In some embodiments, the size of the second display area (e.g., the size of the expansion) may be determined by a size sufficient to accommodate the visual object in the second location. In some cases, the size of the second display area (e.g., the width of the second display area) may be less than the size (e.g., the width) of the visual object, such as in cases in which at least a portion of the visual object remains within the first display area. In other cases, the size of the second display area may be at least the size of the visual object, such as in cases in which the entirety of the visual object is outside the first display area when in the second location. 
     In embodiments, expanding the representation of the physical display may include limiting the expansion of the representation of the physical display to a predetermined threshold size. For example, an expanded area of a target size may be determined to accommodate the visual object at the second location. In this case, the target size may exceed a predetermined threshold size. In response to the target size exceeding the predetermined threshold size, the expanded area may be limited to the threshold size, or the expansion of the display area may be forgone altogether. 
     In some embodiments, the visual object may be moved from the second location to a third location within the first display area. In these embodiments, it may be determined that the expanded display area is no longer necessary to accommodate the visual object. In these cases, the expanded display area may be contracted back to its original pre-expansion size. For example, the second area may no longer be displayed, and instead, only the first display area may be displayed. In embodiments, the contraction of the expanded area may be animated. 
     In embodiments, when the representation of the physical display is expanded, such as by displaying the expanded display area, the representation of the physical display may be curved. For example, the first display area and the second display area may be curved when the expanded display area is displayed. In some embodiments, only the second display area may be curved, while the first display area remains in flat form. In some embodiments, after the expanded display area is contracted, the contracted display area may maintain a curve form. In other embodiments, after the expanded display area is contracted, the contracted display area may be displayed in a flat form. 
     In some embodiments, after expansion, at least a portion of the visual object may be displayed on the first display area, and at least another portion of the visual object may be displayed on the second display area. In this manner, the user may perceive the visual display object as being displayed in a single, coherent display, without indication that the display is an expanded display composed of the original first display area and the additional second display area. 
     Aspects of the present disclosure are directed to systems and techniques that provide functionality for controlling the displaying of representations of a system bar in a display within a CGR environment. In embodiments, controlling the displaying of representations of a system bar in a display may include displaying a first representation of the system bar in a first region of the display (e.g., a physical or virtual display) of the CGR environment, detecting, while the system bar is not selected, an event in a second region of the display, and displaying a second representation of the system bar in the second region when the event meets a system bar movement criteria. In embodiments, the system bar movement criteria may include events that may indicate potential and/or actual user interaction with elements in the second region of the display. For example, the system bar movement criteria may include an opening of an application in the second region of the display, detecting a user&#39;s gaze directed to the second region of the display, detecting a movement of a cursor to the second region of the display, a selection of an interactive element for displaying the second representation of the system bar in the second region of the display, etc. 
       FIGS.  6 A and  6 B  illustrate exemplary techniques for controlling the displaying of representations of a system bar in a display within a CGR environment in accordance with aspects of the present disclosure. In particular,  FIGS.  6 A and  6 B  illustrate an example in which the displaying of representations of a system bar is controlled based on an event that meets a system bar movement criteria that includes a change in a user&#39;s gaze or a change in a cursor position. 
       FIG.  6 A  illustrates user  202  wearing electronic device  200 , which is configured to allow user  202  to view CGR environment  290 . As mentioned above, in some embodiments, electronic device  200  may be similar to electronic device  100   a  described above with reference to  FIGS.  1 A and  1 B . 
     As illustrated in  FIG.  6 A , CGR environment  290  includes display  600 . In embodiments, display  600  may be a representation of a display (e.g., a physical display such as a monitor or screen of a physical computer), such as a computer-generated simulation of a physical display. In some embodiments, the computer-generated simulation of a display may be a computer-generated display area with no corresponding physical counterpart and/or representation. In these cases, the computer-generated simulation of a physical display may be a display area that may not simulate a physical display. In some implementations, the computer-generated simulation of the physical display may be superimposed upon a physical environment, or a representation thereof (e.g., as in MR implementations), such that user  202  may perceive the computer-generated simulation of the physical display superimposed over the physical environment. In other implementations, the computer-generated simulation of the physical display may be a virtual object that is part of a fully CGR environment (e.g., as in VR applications). 
     In some embodiments, display  600  may represent a physical display that is presented to user  202  via electronic device  200 . For example, display  600  may include an actual physical display rather than a computer-generated simulation of the display. In this case, as described above with respect to display  204  of  FIG.  2 A , display  600  may be presented to user  202  such that user  202  may view the physical display, instead of viewing a computer-generated simulation of the physical display. In yet other embodiments, presenting the physical display to user  202  may be performed by superimposing a photorealistic image and/or video of the physical display on a simulated environment. 
     As shown in  FIG.  6 A , display  600  may include regions  601 ,  602 , and  603 . In some embodiments, some, or all, of regions  601 ,  602 , and  603  may be regions in representations of a physical display (e.g., virtual displays), or may be physical displays. In these embodiments, display  600  may represent an aggregated display comprising more than one display. As such, regions  601 ,  602 , and  603  may be determined to be in different representations of physical displays. For example, region  601  may be included in a representation of a first physical display, region  602  may be included in a representation of a second physical display, and region  603  may be included in a representation of a third physical display. 
     In some embodiments, display  600  may be a representation of a single, continuous display (e.g., virtual display or physical display). In these embodiments, regions  601 ,  602 , and  603  may be determined to be regions in the same representation of a physical display. 
     A first representation  620  of a system bar may be displayed by electronic device  200  in a region of display  600 . For example, first representation  620  may be displayed on region  603  of display  600 . In embodiments, first representation  620  may be displayed at any location within region  603 . For example, although first representation  620  is shown as displayed at the bottom of region  603 , first representation  620  may be displayed at the top, left, right, center, etc., of region  603 . In embodiments, the location of first representation  620  in region  603  may be determined by system preferences and/or settings or may be determined by a user (e.g., user  202 ), who may position the system bar at a particular location within region  603 . 
     A system bar, as used herein, may refer to a portion (e.g., strip) of a display area that may be used to display system elements such as system information (e.g., notifications, statuses (e.g., of opened applications), etc.), provide navigation of functions and files within the system, display selectable elements for opening applications (e.g., icons, affordances, etc.), display selectable elements for selecting opened applications (e.g., icons, affordances, etc.), provide application-specific options and/or functions (e.g., when provided in association with a text editor the system bar may present options to open/close/save a file, etc.). In some embodiments, a system bar is a menu with multiple options. In some embodiments, selection of each option in the menu causes an electronic device to perform different operations. 
     In embodiments, an input mechanism may be included to facilitate user interaction. For example, the input mechanism may include a mechanism for a user (e.g., user  202 ) to interact with display  600 . In embodiments, the input mechanism may include a representation of an appendage of the user (e.g., a representation of a finger, hand, leg, foot, etc.), a user&#39;s gaze (e.g., head gaze, eye gaze, etc.), an input device (e.g., a mouse, stylus, pen, touch-sensitive surface, image sensors, etc.), etc. In embodiments, the representation of an appendage of the user may include a virtual representation of the appendage and/or may include data representing characteristics of the appendage (e.g., location, orientation, distance to a particular point, etc.) within the CGR environment. In aspects, the input mechanism may be detected using input sensors (e.g., touch-sensitive surfaces, image-sensors, etc.) configured to perform hand-tracking, head gaze-tracking, eye gaze-tracking, finger-tracking, etc. As shown in  FIG.  6 A , the input mechanism may include a gaze  650  of user  202 , and/or cursor  610 . 
     In embodiments, gaze  650  of user  202  may be detected. Detected gaze  650  may be a head gaze (e.g., the direction in which the user&#39;s head is facing), an eye gaze (e.g., the direction in which the user&#39;s eyes are looking), a combination thereof, etc. Gaze  650  of user  202  may be determined to be focused, placed, or otherwise directed to a particular region of display  600 . For example, gaze  650  of user  202  may be determined to be directed to region  603 , where first representation  620  of the system bar is displayed. Alternatively or additionally, cursor  610  may be determined to be located and/or displayed at a location within region  603 . 
     In embodiments, the input mechanism may be moved. For example, gaze  650  of user  202  may be moved, and the movement of gaze  650  may be detected (e.g., using image sensors, etc.). In embodiments, in response to the detected change in the user&#39;s gaze, a determination of the direction of the new direction of the gaze may be made. 
     In one particular example, first representation  620  displayed in region  603  may be translucent (e.g., semi-transparent). In embodiments, a determination that the new direction of gaze  650  is directed to a new location in region  603  that is closer than the previous location at which gaze  650  was directed may cause first representation  620  to transition from being translucent to being opaque. For example, a determination that the change in gaze  650  indicates that gaze  650  is approaching first representation  620  (e.g., based on a determination that the new direction of gaze  650  is a location within a predetermined distance of first representation  620 ) may cause first representation  620  to become opaque. In embodiments, the opacity of first representation  620  may be based on the distance from the location at which gaze  650  is directed to the location of first representation  620 . For example, as gaze  650  gets closer to first representation  620 , the opacity of first representation  620  may increase. In embodiments, as gaze  650  moves away from first representation  620 , the opacity of first representation  620  may decrease (e.g., first representation  620  may become more translucent). In additional or alternative embodiments, this functionality to vary the opacity of first representation  620  may be based on the movement of cursor  610  toward or away from first representation  620 , and may use a similar technique as discussed above with respect to a change in the user&#39;s gaze (e.g., gaze  650 ). 
     In alternate examples, as illustrated in  FIG.  6 B , a determination may be made that the new direction of gaze  650  may be directed to a region that is different than region  603 , such as directed to region  602 , as illustrated in  FIG.  6 B . In aspects, a representation of the system bar may not currently be displayed in region  602 . As such, the user&#39;s gaze (e.g., gaze  650 ) may be detected in region  602 , region  602  being different from region  603  in which first representation  620  may currently be displayed. The detection of gaze  650  may be determined to be an event in region  602  of display  600 . It is noted that, in some embodiments, rather than detecting a movement of the user&#39;s gaze from region  603  of the display to region  602 , the user&#39;s gaze may be detected in region  602  without detecting the actual movement of the user&#39;s gaze from region  603 . In other words, whether gaze  650  has moved from region  603  to region  602  may not be detected, but gaze  650  may be detected as directed to region  602 . It is noted that, in embodiments, detecting the event in region  602  of display  600 , and also the further steps described below, may occur while the system bar is not selected. For example, the detecting gaze  650  on region  602 , and subsequently displaying a second representation of the system bar, may occur without user  202  selecting and/or interacting with the system bar (e.g., via first representation  620 ). 
     In some embodiments, detecting that gaze  650  is directed to a particular region may include a determination that gaze  650  has remained directed to a location within the particular region for at least a predetermined period of time. For example, a determination may be made that gaze  650  has remained directed to region  602  for a period of time that is less than the predetermined period of time (e.g., the direction of gaze  650  is moved to a different direction before the predetermined period of time expires). In this case, an event in region  602  may not be determined to occur. When it is determined that gaze  650  has remained directed to region  602  for a period of time that is at least the same as the predetermined period of time (e.g., the direction of gaze  650  does not move to a different direction before the predetermined period of time expires), an event in region  602  may be determined to be detected. 
     In embodiments, in response to detecting the event in region  602 , a determination is made as to whether the event meets a system bar movement criteria or not. In the example illustrated in  FIG.  6 B , the event in region  602  may be determined to meet the system bar movement criteria when the event in region  602  is determined to be a user&#39;s gaze (e.g., gaze  650 ) detected in region  602 . 
     In response to a determination that the event in region  602  meets the system bar movement criteria (e.g., gaze  650  is detected in region  602 ), a second representation (e.g., second representation  621 ) of the system bar is displayed in region  602 , as shown in  FIG.  6 B . In embodiments, second representation  621  may have the same size as first representation  620 . In embodiments, second representation  621  may be similar to first representation  620 . For example, second representation  621  may include the same theme, the same information, the same interactive elements (e.g., application icons, affordances, etc.), etc. In some embodiments, second representation  621  may be different from first representation  620 . 
     In embodiments, first representation  620  may continue to be displayed in region  603  while second representation  621  is displayed in region  602 . In some embodiments, first representation  620  may be displayed as translucent in region  603  while second representation  621  is displayed in region  602 . In these embodiments, first representation  620  may transition from translucent to opaque when gaze  650  is determined to move back to region  603 . In other embodiments, first representation  620  may cease to be displayed in region  603  while second representation  621  is displayed in region  602 . 
     In some embodiments, second representation  621  may be displayed in region  602  in the same orientation and/or in the same area as first representation  620  in region  603 . For example, first representation  620  may be displayed as a horizontal bar across the bottom of region  603 . In this case, second representation  621  may be displayed as a horizontal bar across the bottom of region  602 . It will be appreciated that the description of first representation  620  and second representation  621  as being displayed on the bottom of their respective regions is for illustrative purposes and not by way of limitation. Thus, in embodiments, first representation  620  and second representation  621  may be displayed at any of the bottom, top, left, and/or right side of their respective regions. In embodiments, second representation  621  may be displayed in a different orientation and/or in a different area as first representation  620  in region  603 . 
     Alternatively or additionally, the input mechanism may include cursor  610 . In these implementations, as shown in  FIG.  6 B , cursor  610  may be moved from a location in region  603  to a location in region  602 . The movement of cursor  610  from region  603  to region  602  may be detected (e.g., using input sensors, image sensors, etc.). In embodiments, the detection of cursor  610  in region  602  may be determined to be an event in region  602  of display  600 . It is noted that, in some embodiments, rather than detecting a movement of cursor  610  from region  603  of the display to region  602 , cursor  610  may be detected in region  602  without detecting the actual movement of cursor  610  from region  603 . In other words, whether cursor  610  has moved from region  603  to region  602  may not be detected, but cursor  610  may be detected in region  602 . It is noted that, in embodiments, detecting the event in region  602  of display  600 , and also the further steps described below, may occur while the system bar is not selected. For example, the detecting cursor  610  on region  602 , and subsequently displaying a second representation of the system bar, may occur without user  202  selecting and/or interacting with the system bar (e.g., via first representation  620 ). 
     In embodiments, in response to detecting the event in region  602 , a determination may be made as to whether the event meets a system bar movement criteria or not. In the example illustrated in  FIG.  6 B , the event in region  602  may be determined to meet the system bar movement criteria when the event in region  602  is determined to include detecting cursor  610  being moved to region  602 . 
     In response to a determination that the event in region  602  meets the system bar movement criteria (e.g., cursor  610  being moved to region  602 ), a second representation (e.g., second representation  621 ) of the system bar is displayed in region  602 , as shown in  FIG.  6 B , and as discussed above. 
     It is noted that although the foregoing examples, and the examples that follow, may be focused on a description of specific events detected in a second region of the display (e.g., detecting a user&#39;s gaze in the second region, detecting a cursor being moved to the second region, and/or interacting with a selectable element in the second region), this is done for illustrative purposes and is not intended to be limiting in any way. In some embodiments, other events may be detected, and these events may be determined to meet a system movement criteria or not. As will be appreciated, any event indicating a potential and/or actual interaction by a user with the second region (e.g., interaction with UI elements in the second region) may be considered and/or may trigger an event in the second region. 
       FIGS.  7 A and  7 B  illustrate another example of techniques for controlling the displaying of representations of a system bar in a display within a CGR environment in accordance with aspects of the present disclosure. In particular,  FIGS.  7 A and  7 B  illustrate an example in which the displaying of representations of a system bar is controlled based on an event that meets a system bar movement criteria that include an interaction with a selectable UI element. 
       FIG.  7 A  illustrates CGR environment  290  including display  600 . As discussed above, display  600  may be a representation of a display (e.g., a virtual representation of a physical display), a display area, or a physical display. Display  600  may include regions  601 ,  602 , and  603 . As also discussed above, in some embodiments, some, or all, of regions  601 ,  602 , and  603  may be regions in representations of a physical display (e.g., virtual displays), or may be physical displays. In some embodiments, display  600  may be a representation of a single, continuous display (e.g., virtual display or physical display), and regions  601 ,  602 , and  603  may be determined to be regions in the same representation of a physical display. 
     As shown in  FIG.  7 A , a first representation  720  of a system bar may be displayed by electronic device  200  in the bottom area of region  601 . In embodiments, first representation  720  may be displayed at any location within region  601  (e.g., bottom, top, left, right, center, etc.), as described above. In embodiments, a representation of the system bar may not currently be displayed in region  602 . 
     Selectable UI element  630  may be displayed in region  602  of display  600 . In embodiments, region  602  may include a plurality of selectable UI elements, and selectable UI element  630  may be included in the plurality of selectable UI elements. In embodiments, selectable UI element  630  may include an icon, an affordance, a signifier, a button, an interactive UI element, and/or any other UI element configured to allow a user to select the UI element. Selectable UI element  630  may be associated with an application and may be configured to cause, in response to being selected, the associated application to open. 
     For example, as illustrated in  FIG.  7 B , a user (e.g., user  202 ) may interact with selectable UI element  630 . In embodiments, the interaction may be determined to indicate a selection of UI element  630 . In response to the selection of selectable UI element  630 , an associated application (e.g., application  631 ) may be opened and/or displayed in region  602 . 
     In embodiments, the selection of selectable UI element  630 , and/or the opening of application  631  may be detected. In embodiments, the selection of selectable UI element  630 , and/or the opening of application  631  may be determined to be an event in region  602  of display  600 . It is noted that, in embodiments, detecting the event in region  602  of display  600 , and also the further steps described below, may occur while the system bar is not selected (e.g., while a user (e.g., user  202 ) may not select and/or interact with the system bar (e.g., via first representation  720 )). 
     In embodiments, in response to detecting the event in region  602 , a determination is made as to whether the event meets a system bar movement criteria or not. In the example illustrated in  FIG.  7 B , the event in region  602  may be determined to meet the system bar movement criteria when the event in region  602  is determined to be a selection of a selectable UI element (e.g., selectable UI element  630 ) in region  602 , and/or the opening of an application (e.g., application  631 ) in region  602 . 
     In response to a determination that the event in region  602  meets the system bar movement criteria (e.g., selection of selectable UI element  630 , and/or the opening of application  631  is detected in region  602 ), a second representation (e.g., second representation  721 ) of the system bar is displayed in region  602 , as shown in  FIG.  7 B . In embodiments, second representation  721  may have the same size as first representation  720 . In embodiments, second representation  721  may be similar to first representation  720 . For example, second representation  721  may include the same theme, the same information, the same interactive elements (e.g., application icons, affordances, etc.), etc. In some embodiments, second representation  721  may be different than first representation  720 . 
     In embodiments, the first representation may continue to be displayed in region  601  while second representation  721  is displayed in region  602 . In other embodiments, first representation  720  may cease to be displayed in region  601  while second representation  721  is displayed in region  602 . 
     In some embodiments, second representation  721  may be displayed in region  602  in the same orientation (horizontal, vertical, angled, etc.) and/or in the same area (bottom, top, left, and/or right) as first representation  720  in region  601 . In embodiments, second representation  721  may be displayed in a different orientation and/or in a different area as first representation  720  in region  601 . 
       FIGS.  8 A and  8 B  illustrate another example of techniques for controlling the displaying of representations of a system bar in a display within a CGR environment in accordance with aspects of the present disclosure. In particular,  FIGS.  8 A and  8 B  illustrate an example in which the displaying of representations of a system bar in regions of a representation of a display is controlled based on a detected event that meets a system bar movement criteria. 
       FIG.  8 A  illustrates CGR environment  290  including display  600 . As discussed above, display  600  may be a representation of a display (e.g., a virtual representation of a physical display), a display area, or may be a physical display. In embodiments, display  600  may represent a single display or may represent an aggregated display comprising more than one display. In the example illustrated in  FIG.  8 A , display  600  may be a representation of a single display. Display  600  may include regions  670  and  680 . Regions  670  and  680  may be regions within the single representation of display  600 . Regions  670  may be defined by border  671 , and region  680  may be defined by border  681 . In aspects, borders  671  and  681  may not be displayed on display  600  or may be displayed in display  600 . 
     In aspects, display  600  may be a curved display. In some embodiments, display  600  may have a size such that display  600  may partially or fully surround a user (e.g., user  202 ) located in front of display  600 , such that the user may perceive display  600  as a display surrounding him or her. 
     As shown in  FIG.  8 A , a first representation  820  of a system bar may be displayed by electronic device  200  in the bottom area of region  670 . In embodiments, first representation  820  may be displayed at any location within region  670  (e.g., bottom, top, left, right, center, etc.), as described above. In embodiments, a representation of the system bar may not currently be displayed in region  680 . 
       FIG.  8 B  illustrates event  840  being detected in region  680  of display  600 . In embodiments, event  840  may be an event indicating a potential and/or actual interaction by a user (e.g., user  202 ) with region  680 . In embodiments, a determination may be made as to whether event  840  meets a system bar movement criteria or not. For example, a determination may be made as to whether event  840  is at least one of a detection of a user&#39;s gaze in region  680 , a detection of a cursor being moved into region  680 , an detection of an interaction with a selectable element in region  680 , opening of an application in region  680 , any other event indicating a potential and/or actual interaction by a user with region  680 , and/or any combination thereof. 
     It is noted that, in embodiments, detecting event  840  in region  680  of display  600 , and also the further steps described below, may occur while the system bar is not selected (e.g., while a user (e.g., user  202 ) may not select and/or interact with the system bar (e.g., via first representation  720 )). 
     In response to a determination that event  840  in region  680  meets a system bar movement criteria, a second representation (e.g., second representation  821 ) of the system bar is displayed in region  680 , as shown in  FIG.  8 B . In embodiments, second representation  821  may have the same size as first representation  820 . In embodiments, second representation  821  may be similar to first representation  820 . For example, second representation  821  may include the same theme, the same information, the same interactive elements (e.g., application icons, affordances, etc.), etc. In some embodiments, second representation  821  may be different than first representation  820 . 
     In some embodiments, second representation  821  may be displayed in region  680  in the same orientation (horizontal, vertical, angled, etc.) and/or in the same area (bottom, top, left, and/or right) as first representation  820  in region  670 . In embodiments, second representation  821  may be displayed in a different orientation and/or in a different area as first representation  820  in region  670 . 
     In embodiments, first representation  820  may continue to be displayed in region  670  while second representation  821  is displayed in region  680 . In other embodiments, first representation  820  may cease to be displayed in region  670  while second representation  821  is displayed in region  680 . 
     In some embodiments, second representation  821  may be displayed at a location within region  680  based on the location of event  840 . For example, event  840  may be detected in region  680  and may be determined to be at a particular location within region  680  (e.g., location in region  680  at which a user&#39;s gaze may be directed, location in region  680  to which a cursor may be moved, location in region  680  of a UI element with which a user may interact, location in region  680  at which an application may be opened, etc. In these embodiments, second representation  821  may be displayed at the location within region  680  in which event  840  may be detected. In other embodiments, second representation  821  may be displayed at either the bottom, top, right, or left side of region  680  regardless of the location within region  680  in which event  840  may be detected. 
       FIG.  9    is a flow diagram illustrating method  500  for controlling the displaying of representations of a system bar in a display within a CGR environment. In some embodiments, method  900  may be performed by system  100  or a portion of system  100 . In some embodiments, method  900  may be performed by one or more external systems and/or devices. In some embodiments, method  900  may be performed by system  100  (or a portion of system  100 ) in conjunction with one or more external systems and/or devices. 
     At block  902 , the system displays, via a display of an electronic device (e.g., a wearable electronic device, an HMD device, etc.), a virtual display area representing a physical display within a CGR environment. For example, a virtual display area representing a physical display may be displayed via a first display (e.g., a left eye display panel) or second display (e.g., a second eye display panel) of an electronic device. 
     In aspects, the virtual display area may represent a curved display. In some embodiments, the virtual display area may represent a curved display having a size such that the display may partially or fully surround a user located in front of the represented display, such that the user may perceive the display as a display surrounding him or her. 
     In embodiments, the virtual display area may be a representation of a single, continuous physical display. In other embodiments, the virtual display area may be a representation of more than one physical display (e.g., an aggregation of more than one physical display). In embodiments, the virtual display area may include at least one region configured for displaying UI elements and for displaying a representation of a system bar. 
     At block  904 , the system displays a first representation of a system bar in a first region of the virtual display. In embodiments, the first representation of the system bar may be a virtual representation displayed within the CGR environment. In embodiments, the first representation may be displayed at any location within the first region (e.g., bottom, top, left, right, center, etc.). In embodiments, a representation of the system bar may not currently be displayed in another region of the virtual display area. In embodiments, the system bar may include a plurality of affordances, icons, and/or selectable UI elements. 
     At block  906 , the system detects an event in a second region of the virtual display. In aspects, the second region of the virtual display may be outside of the first region of the virtual display. In embodiments, the detected event may be an event indicating a potential and/or actual interaction by a user with the second region. In embodiments, a determination may be made as to whether the event meets a system bar movement criteria or not. For example, a determination may be made as to whether the event is at least one of a detection of a user&#39;s gaze in the second region, a detection of a cursor being moved into the second region, a detection of an interaction with a selectable element in the second region, opening of an application in the second region, any other event indicating a potential and/or actual interaction by a user with the second region, and/or any combination thereof. 
     At block  908 , the system displays a second representation of the system bar in the second region when a determination is made that the event meets the system bar movement criteria. In embodiments, detecting the event in the second region and displaying the second representation of the system bar when the event meets the system bar movement criteria may occur while the system bar is not currently selected (e.g., while a user (e.g., user  202 ) may not select and/or interact with the system bar (e.g., via the first representation)). 
     In embodiments, the second representation of the system bar may have the same size as the first representation. In embodiments, the second representation may be similar to the first representation (e.g., the second representation may include the same theme, the same information, the same interactive elements (e.g., application icons, affordances, etc.), etc., as the first representation). In some embodiments, the second representation may be different from the first representation. 
     In some embodiments, the second representation may be displayed in the second region in the same orientation (horizontal, vertical, angled, etc.) and/or in the same area (bottom, top, left, and/or right) as the first representation in the first region. In embodiments, the second representation may be displayed in a different orientation and/or in a different area from the first representation in the first region. 
     In embodiments, the first representation may continue to be displayed in the first region while the second representation is displayed in the second region. In other embodiments, the first representation may cease to be displayed in the first region while the second representation is displayed in the second region. 
     In embodiments, the first representation may continue to be displayed in the first region as a translucent object, while the second representation may be displayed in the second region as an opaque object. In embodiments, the first representation may transition from translucent to opaque when a user&#39;s gaze or a cursor is determined to move into the first region. 
     Aspects of the present disclosure are directed to systems and techniques that provide functionality for controlling the displaying of a virtual display window based on a hinge angle of a physical device within a CGR environment. In embodiments, controlling whether a virtual display window is manifested (e.g., displayed within the CGR environment) may include displaying the virtual display window adjacent to the physical device (e.g., adjacent to a display of the physical device) when a hinge angle of the physical device reaches a threshold hinge angle. 
       FIGS.  10 A- 10 J  illustrate exemplary techniques for controlling the displaying of a virtual display window based on a hinge angle of a physical device within a CGR environment in accordance with aspects of the present disclosure. 
       FIG.  10 A  illustrates physical device  1000  within CGR environment  1090 . In embodiments, physical device  1000  may be a device with a hinging functionality, in which at least two portions of the physical device may be configured to turn about a hinge point and come together or separate from each other. For example, physical device  1000  may include portion  1020  and portion  1021 , both of which may be configured to hinge about hinge point  1010 . In embodiments, portions  1020  and  1021  may separate from each other while remaining attached at hinge point  1010 . In embodiments, physical device  1000  may be any device with such hinging functionality (e.g., a laptop, a smartphone, a folding tablet, a briefcase, etc.). 
     In embodiments, physical device  1000  may be part of CGR environment  1090 . For example, as discussed above, physical device  1000  may be presented (e.g., to a user (e.g., user  202 )) via a transparent or translucent display of electronic device  200 , or may be presented via pass-through video as described above, such that the actual physical device  1000  may be perceived. 
     In embodiments, a hinge angle of physical device  1000  may be measured by measuring the angle of the separation between portion  1020  and portion  1021 . For example, as shown in  FIG.  10 B , a current hinge angle of physical device  1000  may be determined to be zero. That is, portion  1020  and portion  1021  may be together. 
       FIG.  10 C  illustrates a hinge action upon physical device  1000 . In embodiments, either portion  1021  or portion  1021 , or both, may hinge about hinge point  1010  to separate from each other. In the example illustrated in  FIG.  10 C , portion  1020  may hinge about hinge point  1010  in direction  1040  away from portion  1021 . For example, physical device  1000  may be determined to be opened by the hinging action of portion  1020  away from portion  1021 . The hinging action may create hinge angle  1050  between portions  1020  and  1021 . 
       FIG.  10 D  illustrates the hinging action of portion  1020  rotating about hinge point  1010  and moving away from portion  1021 , thereby creating current hinge angle  1050  between portion  1020  and portion  1021 . In embodiments, current hinge angle  1050  may be measured. For example, image sensors may be used to track the location of portions  1020  and  1021  relative to each other to measure current hinge angle  1050 . In other implementations, sensors in physical device  1000  may be used to measure current hinge angle  1050 , and physical device  1000  may provide data representative of the hinge angle to device  200 . 
     In embodiments, threshold hinge angle  1051  may be provided. Threshold hinge angle  1051  may be a predetermined hinge angle against which the current hinge angle may be measured. In embodiments, threshold hinge angle  1051  may be an angle with respect to portion  1021 , portion  1021  being a bottom portion of physical device  1000 . In embodiments, threshold hinge angle  1051  may be displayed as a virtual object within CGR environment (e.g., as a line, broken line, point, etc.). In some embodiments, threshold hinge angle  1051  may not be displayed. 
     In embodiments, a determination may be made as to whether the measured current hinge angle exceeds the threshold hinge angle or not. For example, current hinge angle  1050  may be compared against threshold hinge angle  1051  to determine if current hinge angle  1050  exceeds threshold hinge angle  1051  or not. When a determination is made that the current hinge angle does not exceed the threshold hinge angle, a virtual display window may not be manifested. In embodiments, not manifesting the virtual display window may include forgoing to display the virtual display window in accordance with the description below. Conversely, when a determination is made that the measured hinge angle exceeds the threshold hinge angle, a virtual display window may be manifested. 
     As illustrated in  FIGS.  10 C and  10 D , current hinge angle  1050  does not exceed threshold hinge angle  1051 . In accordance with the determination that current hinge angle  1050  does not exceed threshold hinge angle  1051 , a virtual display window may not be manifested. 
       FIGS.  10 E and  10 F  illustrate a further hinging action of portion  1020  rotating about hinge point  1010  and moving further away from portion  1021  in direction  1040 . In this example, current hinge angle  1050  has increased. In embodiments, a determination may be made as to whether current hinge angle  1050  now exceeds threshold hinge angle  1051  or not. For example, current hinge angle  1050  may be compared against threshold hinge angle  1051  to determine in current hinge angle  1050  exceeds threshold hinge angle  1051  or not. As illustrated in  FIGS.  10 E and  10 F , current hinge angle  1050  does not exceed threshold hinge angle  1051 . In accordance with the determination that current hinge angle  1050  does not exceed threshold hinge angle  1051 , a virtual display window may not be manifested. 
     In some embodiments, physical device  1000  may be configured with a display (e.g., display  1030 . Physical device  1000  may also be configured such that display  1030  may be inactive and/off (e.g., not displaying content or displaying wholly dark or black screen) until a particular hinge angle has been reached. When the hinge angle of physical device  1000  reaches the particular hinge angle, display  1030  may be turned on or activated. In the example illustrated in  FIG.  10 E , hinge angle  1050 , while perhaps not exceeding threshold hinge angle  1051 , has reached the hinge angle to activate display  1030 . In this case, display  1030  may be activated. In embodiments, activating display  1030  may include displaying at least a portion of content in display  1030 . For example, display  1030  may be activated, and content  1031  and content  1032  may be displayed in display  1030 . In embodiments, content  1031  and content  1032  may be different contents, may be portions of a content or may be different portions of the same content. 
       FIGS.  10 G and  10 H  illustrates a yet further hinging action of portion  1020  rotating about hinge point  1010  and moving even further away from portion  1021 . In this example, current hinge angle  1050  has increased further. In embodiments, a determination may be made as to whether current hinge angle  1050  now exceeds threshold hinge angle  1051  or not. For example, current hinge angle  1050  may be compared against threshold hinge angle  1051  to determine in current hinge angle  1050  exceeds threshold hinge angle  1051  or not. As illustrated in  FIGS.  10 E and  10 F , current hinge angle  1050  exceeds threshold hinge angle  1051 . In accordance with the determination that current hinge angle  1050  exceeds threshold hinge angle  1051 , a virtual display window may be manifested. 
     In embodiments, manifesting a virtual display window may include displaying at least one virtual display window within CGR environment  1090  relative to the physical device. In embodiments, the virtual display window may be displayed at any region within CGR environment  1090  that facilitates configuring the virtual display window as connected to the physical device. In embodiments, for example, where the physical device may not have a display, the virtual display window may be displayed to represent a display of the physical device. In some embodiments, for example, where the physical device may have a display, the virtual display window may be displayed as connected to a display of the physical device (e.g., as an extension of the display of the physical device). In embodiments, the size of the virtual display window may be the same as the size of the display of the physical device. In other embodiments, the size of the virtual display window may be different from the size of the display of the physical device. In these cases, the size of the virtual display window may be determined based on system preferences and/or settings, and/or may be determined based on environmental characteristics. For example, the size of the virtual display window may be determined to accommodate a desk (e.g., a virtual desk, or physical desk) within the CGR environment where physical device  1000  may be laid. 
     In the example illustrated in  FIG.  10 G , virtual display window  1060  may be displayed, when it is determined that current hinge angle  1050  exceeds threshold hinge angle  1051 , in a region above the physical device  1000  and connected to display  1030  of physical device  1000 . In this example, virtual display window  1060  extends display  1030  upwards. In some embodiments, additional virtual display windows may be displayed. For example, virtual display window  1061  may be displayed to the left of physical device  1000  to extend display  1030  leftwards, and/or virtual display window  1062  may be displayed to the right of physical device  1000  to extend display  1030  rightwards. As will be appreciated, additional or less virtual display windows may be displayed. For example, in embodiments, additional virtual display windows may be displayed such that an entire region comprising the virtual display windows and physical display  1030  represent a single, coherent, extended display. 
     In embodiments, displaying virtual display window  1060 , and ceasing to display virtual display window  1060  as described below, may be performed gradually. In embodiments, displaying virtual display window  1060  may include initially displaying virtual display window  1060  with a high transparency (e.g., non-zero transparency) and gradually decreasing the transparency of virtual display window  1060  until virtual display window  1060  is rendered opaque. In some embodiments, the transparency of virtual display window  1060  may depend on the hinge angle of physical device  1000 . In embodiments, the size of virtual display window  1060  may also be increased gradually, and in some embodiments, the size of virtual display window  1060  may depend on the hinge angle. 
     In embodiments, at least a portion of the content displayed in display  1030  of physical device  1000  may be displayed in the virtual display window. For example, as shown in  FIG.  10 G , content  1031 , which was previously displayed in display  1030 , may be displayed in virtual display window  1060 . In embodiments, which portion of content previously displayed in the display of the physical device may be displayed in the virtual display window may be determined automatically upon the display of the virtual window. For example, content  1031  and content  1032  may be portions of content that represents a coherent element (e.g., an image, an application window, etc.). In this case, when virtual display window  1060  is displayed in response to the hinge angle of physical device  1000  exceeding threshold hinge angle  1051 , the coherent element may be increased in size, portion  1031  may be moved to virtual display window  1060 , and portion  1031  may remain displayed in display  1030 . In embodiments, content  1031  and content  1032  may not be portions of content that represents a coherent element, but nevertheless, at least a portion of the content may be moved to virtual display window  1060 . In some embodiments, a user (e.g., user  202 ) may select content to move to virtual display window  1060 . 
     In embodiments, content may be displayed in the virtual display window that was not previously displayed in the display of the physical device. For example, content  1033  may not previously be displayed in display  1030  of physical device  1000 . In this case, when virtual display window  1060  is displayed in response to the hinge angle of physical device  1000  exceeding threshold hinge angle  1051 , content  1033  may be displayed in virtual display window  1060 . 
     In embodiments, content displayed in the virtual window may be concurrently displayed (e.g., shared) in the physical display. For example, content  1033  may be displayed in display  1030  of physical device  1000 . In response to a user input (e.g., a selection of an interactive element, a dragging gesture, a click, etc.), content  1033  may be concurrently displayed (e.g., shared) in physical display  1030 . In this manner, a user viewing CGR environment  1090 , and who may perceive virtual display window  1060  via device  200 , may share virtual content from the CGR environment, via the real-world physical display (e.g., display  1030 ), to other users who may not be able to perceive CGR environment  1090 . 
     In embodiments, virtual display window  1060  may be displayed a particular tilt angle with respect to physical device  1000 . In embodiments, the tilt angle of virtual display window  1060  may be the same as the hinge angle of portion  1020 . In other embodiments, the tilt angle of virtual display window  1060  may be fixed and/or predetermined. In these cases, even if the hinge angle of physical device changes, the tilt angle of virtual display window  1060  may remain the same (e.g., as long as the hinge angle of the physical device exceeds the threshold hinge angle). 
       FIGS.  10 I and  10 J  illustrate a hinging action in which portion  1020  rotates about hinge point  1010  in direction  1041  towards portion  1021 . In this example, based on direction  1041 , it may be determined that physical device  1000  is being closed. In this example, it may be determined that current hinge angle  1050  has decreased. In embodiments, a determination may be made as to whether current hinge angle  1050  exceeds threshold hinge angle  1051  or not. For example, current hinge angle  1050  may be compared against threshold hinge angle  1051  to determine in current hinge angle  1050  exceeds threshold hinge angle  1051  or not. As illustrated in  FIG.  10 J , current hinge angle  1050  no longer exceeds threshold hinge angle  1051 . In accordance with the determination that current hinge angle  1050  does not exceed threshold hinge angle  1051 , the displaying of the virtual display window (e.g., virtual display window  1060 ,  1061 ,  1062 , and/or any combination thereof) is ceased. 
     In embodiments, ceasing to display the virtual display window may include moving at least a portion of the content displayed in the virtual display window to display  1030  of physical device  1000 . In embodiments, the content that is moved to display  1030  may include content that was previously displayed in display  1030  but was moved to the virtual display window, and/or may include content that was displayed in the virtual display window but not previously displayed in display  1030 . 
     In embodiments, as described above, ceasing to display the virtual display window may be performed gradually. For example, the transparency of the virtual display window may be gradually increased until the virtual display window ceases to be visible. In alternative or additional embodiments, ceasing to display the virtual display window may include gradually decreasing the size of the virtual display window until the window ceases to be visible. 
       FIG.  11    is a flow diagram illustrating method  1100  for controlling the displaying of a virtual display window based on a hinge angle of a physical device within a CGR environment. In some embodiments, method  1100  may be performed by system  100  or a portion of system  100 . In some embodiments, method  1100  may be performed by one or more external systems and/or devices. In some embodiments, method  1100  may be performed by system  100  (or a portion of system  100 ) in conjunction with one or more external systems and/or devices. In embodiments, method  1100  may be performed by an electronic device (e.g., a wearable electronic device, an HMD device, etc.). 
     At block  1102 , the system receives and/or obtains data representative of a hinge angle of a physical object. In embodiments, the hinge angle of the physical device may be measured using image sensors, sensors in the physical device, using computer vision techniques that may employ forward-facing camera, etc. 
     In embodiments, in response to obtaining the data representative of the hinge angle of the physical device, a determination may be made as to whether the hinge angle of the physical device exceeds a threshold hinge angle or not. For example, the hinge angle may be compared against the threshold hinge angle to determine if the hinge angle exceeds the threshold hinge angle or not. When a determination is made that the hinge angle does not exceed the threshold hinge angle, a virtual display window may not be manifested. In embodiments, not manifesting the virtual display window may include forgoing to display the virtual display window. 
     At block  1104 , the system displays, via a display of the electronic device (e.g., a wearable electronic device, an HMD device, etc.), a virtual display window relative to the physical device when a determination is made that the hinge angle exceeds a threshold hinge angle, in response to obtaining the data representative of the hinge angle of the physical device. For example, a virtual display area relative to the physical device may be displayed via a first display (e.g., a left eye display panel) or second display (e.g., a second eye display panel) of an electronic device. 
     In embodiments, the virtual display window may be displayed at any region within the CGR environment that facilitates configuring the virtual display window to be displayed as connected to the physical device. In embodiments, the virtual display window may be displayed as connected to a display of the physical device (e.g., as an extension of the display of the physical device). In embodiments, the size of the virtual display window may be the same as the size of the display of the physical device. In other embodiments, the size of the virtual display window may be different from the size of the display of the physical device. 
     In embodiments, the virtual display window may be displayed in a region above the physical device. In some embodiments, additional or alternative virtual display windows may be displayed (e.g., on the left or right of the physical device). 
     In embodiments, displaying the virtual display window, and ceasing to display the virtual display window, may be performed gradually. For example, displaying the virtual display window may include initially displaying the virtual display window with a high transparency and gradually decreasing the transparency of the virtual display window until the virtual display window is rendered opaque. In embodiments, the size of the virtual display window may be increased gradually until reaching a determined size when the virtual display window is displayed. 
     In embodiments, at least a portion of the content displayed in a display of the physical device may be displayed in the virtual display window. For example, when the virtual display window is displayed in response to the hinge angle of the physical device exceeding the threshold hinge angle, at least a portion of the content that was previously displayed in the display of the physical device may be moved to the virtual display window. 
     In embodiments, content displayed in the virtual display window may be concurrently displayed (e.g., shared) in the physical display. For example, in response to a user input (e.g., a selection of an interactive element, a dragging gesture, a click, etc.), content displayed in the virtual display window may be concurrently displayed (e.g., shared) in the display of the physical device. In this manner, a user presented with the CGR environment, and who may perceive the virtual display window via the electronic device, may share virtual content from the CGR environment, via a real-world physical display, to other users who may not be able to perceive the CGR environment. 
     In embodiments, the virtual display window may be displayed at a particular tilt angle with respect to the physical device. In embodiments, the tilt angle of the virtual display window may be maintained even if the hinge angle and/or a tilt angle of the physical device changes. 
     In embodiments, in response to detecting that the hinge has changed, a determination may be made as to whether the new hinge angle of the physical device exceeds the threshold hinge angle or not. When a determination is made that the new hinge angle does not exceed the threshold hinge angle, the displaying of the virtual display window may be ceased. 
     In embodiments, ceasing to display the virtual display window may include moving at least a portion of content displayed in the virtual display window to the display of the physical device. In embodiments, the content that is moved to the display of the physical device may include content that was previously displayed in the display of the physical device but was moved to the virtual display window, and/or may include content that was displayed in the virtual display window but not previously displayed in the display of the physical device. 
     In embodiments, as described above, ceasing to display the virtual display window may be performed gradually. For example, the transparency of the virtual display window may be gradually increased until the virtual display window ceases to be visible. In alternative or additional embodiments, ceasing to display the virtual display window may include gradually decreasing the size of the virtual display window until the window ceases to be visible. 
     Aspects of the present disclosure are directed to systems and techniques that provide functionality for controlling the displaying of UI elements based on a gaze within a CGR environment. In embodiments, controlling the displaying of a UI element (e.g., a cursor, an application window, etc.) based on a gaze within a CGR environment may include displaying the UI element at a first position within the CGR environment, detecting a current gaze of a user within the CGR environment, and, upon receiving a request that meets moving criteria, displaying the UI element at a lead-in position and then moving the UI element from the lead-in position to a second position determined based on the user&#39;s gaze. 
       FIGS.  12 A- 12 E  illustrate exemplary techniques for controlling the displaying of UI element based on a gaze within a CGR environment in accordance with aspects of the present disclosure. In particular,  FIG.  12 A  illustrates user  202  wearing electronic device  200 , which is configured to allow user  202  to view CGR environment  1290 . As mentioned above, in some embodiments, electronic device  200  may be similar to electronic device  100   a  described above with reference to  FIGS.  1 A and  1 B . 
     As illustrated in  FIG.  12 A , CGR environment  1290  includes display  1200 . In embodiments, display  1200  may be a representation of a display (e.g., a physical display such as a monitor or screen of a physical computer), such as a computer-generated simulation of a physical display. In some embodiments, the computer-generated simulation of a display may be a computer-generated display area with no corresponding physical counterpart and/or representation. In these cases, the computer-generated simulation of a physical display may be a display area that may not simulate a physical display. In some implementations, the computer-generated simulation of the physical display may be superimposed upon a physical environment, or a representation thereof (e.g., as in MR implementations), such that user  202  may perceive the computer-generated simulation of the physical display superimposed over the physical environment. In other implementations, the computer-generated simulation of the physical display may be a virtual object that is part of a fully CGR environment (e.g., as in VR applications). 
     In some embodiments, display  1200  may represent a physical display that is presented to user  202  via electronic device  200 . For example, display  1200  may include an actual physical display and may not be a computer-generated simulation of the display. In this case, as described above with respect to display  204  of  FIG.  2 A , display  1200  may be presented to user  202  such that user  202  may view the physical display, instead of viewing a computer-generated simulation of the physical display. In yet other embodiments, presenting the physical display to user  202  may be performed by superimposing a photorealistic image and/or video of the physical display on a simulated environment. 
     In aspects, display  1200  may be a curved display. In some embodiments, display  1200  may extend such that display  1200  may partially or fully surround user  202 , such that user  202  may perceive display  1200  as a display surrounding him or her. 
     In embodiments, an input mechanism may be included to facilitate user interaction. For example, the input mechanism may include a mechanism for a user (e.g., user  202 ) to interact with display  1200  or with UI elements of display  1200 . In embodiments, the input mechanism may include a representation of an appendage of the user (e.g., a virtual representation of a finger, hand, leg, foot, etc.), a user&#39;s gaze (e.g., head gaze, eye gaze, etc.), an input device (e.g., a mouse, stylus, pen, touch-sensitive surface, image sensors, etc.), etc. In embodiments, the representation of an appendage of the user may include a virtual representation of the appendage and/or may include data representing characteristics of the appendage (e.g., location, orientation, distance to a particular point, etc.) within the CGR environment. In aspects, the input mechanism may be detected using input sensors (e.g., touch-sensitive surfaces, image-sensors, etc.) configured to perform hand-tracking, head gaze-tracking, eye gaze-tracking, finger-tracking, etc. 
     In embodiments, UI elements associated with the input mechanisms may be provided. For example, as illustrated in  FIG.  12 A , a UI element  1210  may be provided and displayed in display  1200 . In embodiments, UI element  1210  may be a cursor, an application window, etc. In this example, a current location of UI element  1210  within CGR  1290  may be location  1220 . Additionally, the input mechanism may include gaze  1250  of user  202 . In particular, it is noted that gaze  1250  may have a direction associated with it, and thus gaze  1250  may be directed to a particular location within CGR environment  1290 . 
     In embodiments, a gaze, and a direction of the gaze, may be detected. For example, gaze  1250  of user  202 , which may be a head gaze (e.g., the direction in which the user&#39;s head is facing), an eye gaze (e.g., the direction in which the user&#39;s eyes are looking), a combination thereof, etc., may be detected using input and/or image sensors. 
       FIG.  12 B  shows that gaze  1250  of user  202  has moved. In particular, it is shown that gaze  1250  is directed to location  1221 . Location  1221  may be a location within area  1201  of display  1200 . As illustrated, area  1201  may be defined by border  1202 . 
     In embodiments, gaze  1250 , directed to location  1221  in area  1201 , may be detected using input sensors and/or image sensors. As such, it may be determined that the current gaze of user  202  (e.g., gaze  1250 ) may be directed to location  1221 , and/or directed to area  1201 . Furthermore, as noted above, gaze  1250  may be a head gaze, in which case it may be determined that the user&#39;s head is directed to location  1221  and/or area  1201 , or may be an eye gaze, in which case it may be determined that the user&#39;s eyes are directed to location  1221  and/or area  1201 . 
     In embodiments, gaze  1250  may be used to determine a second location within CGR environment  1290 . The second location may be a location to which UI element  1210  is to be moved. In embodiments, the second location may be a point (e.g., location  1221 ) or may be an area (e.g., area  1201 ), and may be determined based on the location at which gaze  1250  is directed. For example, as gaze  1250  is directed to location  1221  and area  1201 , the second location may be determined to be location  1221  or location  1201 . In some embodiments, for example, where the second location is determined to be an area, the particular location within the area at which UI element  1210  is to be moved may be a snap point. In these cases, UI element  1210  may be moved to the area (e.g., area  1201 ), but may be snapped to the snap location (e.g., location at which the user&#39;s gaze is directed, or a default location). In embodiments, the second location may be based on a UI element upon which the user is determined to be looking. For example, based on gaze  1250 , it may be determined that user  202  may be looking at a UI element at location  1221  (e.g., a particular selectable UI element, a status UI element (e.g., a time icon, etc.), a system element (e.g., system display icon, etc.), etc.). 
     In some embodiments, the second location may be determined based on a dwell time of gaze  1250 . For example, gaze  1250  may be detected at area  1201 , and it may be determined that gaze  1250  is directed to location  1221 . In this case, location  1221  may be determined to be the second location when gaze  1250  is determined to remain directed at (e.g., dwell on) location  1250  for at least a predetermined period of time. If gaze  1250  does not remain directed at location  1250  for at least the predetermined period of time, the second location is not determined. 
     In some embodiments, the second location may be determined based on gaze  1250  being directed to a particular UI element. For example, when gaze  1250  is directed to a particular UI element in area  1201 , area  1201 , or a location within area  1201  (e.g., a snap location or the location within area  1201  at which gaze  1250  may be directed) may be determined as the second location. In embodiments, a particular UI element may be provided in area  1201 , where the particular UI element may be configured to indicate a request to move UI element  1210  to area  1201  and/or to the location where the particular UI element is displayed. In these cases, the particular UI element may be determined to be selected when gaze  1250  is directed to the particular UI element (e.g., for at least a predetermined amount of time), and area  1201 , or a location within area  1201  (e.g., a snap location or the location of the particular UI element) may be determined as the second location. 
     In embodiments, determining to move UI element  1210  may be based on a request to move UI element  1210  meeting a movement criteria. For example, a request to move UI element  1210  may be received. In embodiments, a request to move UI element  1210  may include an actual movement of UI element  1210 . For example, the input mechanism (e.g., a mouse, stylus, pen, touch-sensitive surface, image sensors, etc.) associated with UI element  1210 , or configured to control UI element  1210 , may be moved (e.g., by user  202 ), which may normally cause a corresponding movement of UI element  1210  within display  1200 . In embodiments, the movement of the input mechanism may be determined to be a request to move UI element  1210 . In embodiments, the request to move UI element  1210  may include a click and hold of an input mechanism. In embodiments, a determination may be made as to whether the request to move UI element  1210  meets the movement criteria or not. 
     In embodiments, the request to move UI element  1210  may be determined to meet the movement criteria when a second location has been determined based on the user&#39;s gaze (e.g., gaze  1250 ). In these cases, a determination of the second location may indicate that the user&#39;s gaze (e.g., gaze  1250 ) has been detected as directed to area  1201  and/or location  1221 , detected as dwelling on a location for at least a predetermined period, and/or detected as directed at a particular element in area  1201 , as described above. 
     In embodiments, the request to move UI element  1210  may be determined to meet the movement criteria when, additionally, the movement of the input mechanism exceeds a threshold amount of movement. For example, as shown in  FIG.  12 B , gaze  1250  may be directed to area  1201  and/or location  1221 . In this example, an input mechanism may be moved by an input mechanism movement distance. The input mechanism movement distance may be compared against a threshold amount of movement. If the input mechanism movement distance exceeds the threshold amount of movement, the request to move UI element  1210  may be determined to meet the movement criteria. Conversely, if the input mechanism movement distance does not exceed the threshold amount of movement, the request to move UI element  1210  may be determined not to meet the movement criteria. 
     In embodiments, the request to move UI element  1210  may be determined to meet the movement criteria when, additionally, the movement of the input mechanism is in a particular direction. For example, as shown in  FIG.  12 B , gaze  1250  may be directed to area  1201  and/or location  1221 . In this example, an input mechanism may be moved in direction  1231 , towards area  1201  and location  1221 . In this example, as the movement direction of the input mechanism is towards the location and/or area at which gaze  1250  is directed, the request to move UI element  1210  may be determined to meet the movement criteria. Conversely, if the movement direction of the input mechanism is not towards the location and/or area at which gaze  1250  is directed, the request to move UI element  1210  may be determined not to meet the movement criteria. 
     In embodiments, the request to move UI element  1210  may be determined to meet the movement criteria when, additionally, gaze  1250  is directed to a particular type of application. For example, gaze  1250  may be directed to an application displayed in area  1201 . In this example, the input mechanism associated with UI element  1210  may be moved. If the application at which gaze  1250  is directed is of a particular type, the request to move UI element  1210  may be determined to meet the movement criteria. Conversely, if the application at which gaze  1250  is directed is not of a particular type, the request to move UI element  1210  may be determined not to meet the movement criteria. 
     In embodiments, when the request to move UI element  1210  is determined to meet the movement criteria, as described above, UI element  1210  may be moved to the second location. As shown in  FIG.  12 B , the second location may be determined to be location  1221 , in accordance with the description above. As also shown, there is a distance  1230  between the current location  1220  of UI element  1210  and the second location (e.g., location  1221 ). Thus, in order to move UI element  1210  to location  1221 , distance  1230  needs to be traversed. As will be appreciated, moving UI element  1210  from location  1220  to location  1221  may include dragging UI element  1210  across display  1200 , in correspondence with the movement of the input mechanism (e.g., a mouse, stylus, pen, touch-sensitive surface, image sensors, etc.)), to the second location (e.g., location  1221 ). However, this dragging movement may take a long time, and in some cases, the user may lose track of where UI element  1210  is. This is particularly significant when a display in which the UI element being displayed is a large display (e.g., a display substantially or wholly surrounding a user). On the other hand, moving UI element  1210  from location  1220  to location  1221  may include teleporting UI element  1210  from location  1220  to location  1221 . For example, UI element  1210  may be displayed at location  1221  while simultaneously being ceased to be displayed at location  1220 . However, teleporting UI element  1210  from location  1220  to location  1221  might cause an undesirable effect, e.g., upon the sudden appearance of UI element  1210  in the new location  1221 . In addition, the user may lose sight of UI element  1210  in location  1221 , especially when the new location  1221  may include content being displayed, which might obscure where the UI element is to be displayed. 
     In embodiments, moving UI element  1210  to location  1221  may include a two-stage process. In embodiments, the two-stage process of embodiments may be configured to facilitate a user perceiving the movement of the UI element to the new location and/or area without an undesirable surprise and may render the movement of UI element  1210  to location  1221  easier to follow and perceive. In embodiments, the two-stage process may include teleporting UI element  1210  from location  1220  to a lead-in location different from location  1221 , and moving (e.g., dragging) UI element from the lead-in location to location  1221 . 
       FIG.  12 C  shows UI element  1210  being teleported from location  1220  to lead-in location  1222 . In embodiments, teleporting UI element  1210  from location  1220  to lead-in location  1222  may include displaying UI element  1210  at lead-in location  1222  while simultaneously, or near-simultaneously, ceasing to display UI element  1210  at location  1220 . The effect is that UI element  1210  seems to teleport from location  1220  to location  1222 . 
     In embodiments, lead-in location  1222  may be determined based on the second location (e.g., location  1221 ). For example, the lead-in location may be determined to be a location at a predetermined distance, in the direction of location  1220 , from the second location. In embodiments, lead-in location  1222  may also be a location determined based on the area in which the second location is located. For example, each area of display  1200  may have a predetermined lead-in location. For example, lead-in location  1222  may be a predetermined lead-in location for area  1201 . 
       FIG.  12 D  shows UI element  1210  initially being moved from lead-in location  1222  to location  1221  after being teleported to lead-in location  1222  from location  1220 .  FIG.  12 E  shows UI element  1210  moved to location  1221 . In embodiments, moving element  1210  from lead-in location  1222  to location  1221  may be animated, and a user may perceive that UI element  1210  moves, slides, or is otherwise dragged from lead-in location  1222  to location  1221 . In some embodiments, audio may also be played as part of the animation of the moving of UI element  1210  from lead-in location  1222  to location  1221 . In some embodiments, different audio may be played when UI element  1210  is teleported to lead-in location  1222  from location  1220 . 
       FIG.  13    is a flow diagram illustrating method  1300  for controlling the displaying of a UI element based on a gaze within a CGR environment. In some embodiments, method  1300  may be performed by system  100  or a portion of system  100 . In some embodiments, method  1300  may be performed by one or more external systems and/or devices. In some embodiments, method  1300  may be performed by system  100  (or a portion of system  100 ) in conjunction with one or more external systems and/or devices. 
     At block  1302 , the system displays, via a display of an electronic device (e.g., a wearable electronic device, an HMD device, etc.), a UI element at a first position within a CGR environment. For example, a UI element may be displayed at a first position within a CGR environment via a first display (e.g., a left eye display panel) or second display (e.g., a second eye display panel) of an electronic device. 
     In embodiments, the first position at which the UI element is displayed may be a location within a virtual display. In embodiments, the virtual display may represent a curved display having a size such that the display may partially or fully surround a user, such that the user may perceive the display as a display surrounding him or her. 
     In embodiments, the UI element may be a UI element (e.g., a cursor) associated with an input mechanism (e.g., a mouse, stylus, pen, touch-sensitive surface, image sensors, etc.), and the input mechanism may be configured to control the UI element. For example, UI element may be moved based on a corresponding movement of the associated input mechanism. In embodiments, the UI element may be an application window. 
     At block  1304 , the system detects a current gaze of the user within the CGR environment. For example, a gaze of the user may be detected using input sensors and/or image sensors. In embodiments, the gaze of the user may be head gaze, eye gaze, or a combination thereof. In embodiments, detecting the current gaze of the user may include detecting a direction to which the current gaze is directed. In embodiments, the current gaze may be determined to be directed at a particular location and/or area within the CGR environment. 
     At block  1306 , the system determines, based on the current gaze of the user, a second position within the CGR environment. In embodiments, the second position is different from the first position. For example, the second position may be a position in a different area and/or a different location within the CGR environment than the area and/or location of the first position. 
     In embodiments, for example, where the second position is determined to be an area, the location within the area at which the UI element is to be moved may be a snap point. In these embodiments, the UI element may be moved to the second position (e.g., an area) and may be snapped to the snap location. In embodiments, the second position may be based on a UI element upon which the user is determined to be looking. In embodiments, the second position may be determined based on a dwell time of the gaze of the user. For example, the second position may be determined to be a location at which the gaze of the user remains directed (e.g., dwells) for at least a predetermined period of time. 
     At block  1308 , the system receives a request to move the UI element. In embodiments, the request to move the UI element may include a movement of the input mechanism (e.g., a mouse, stylus, pen, touch-sensitive surface, image sensors, etc.) associated with the UI element. In embodiments, the request to move the UI element may be a request to move the UI element a movement distance or may be a request to move the UI element in a movement direction. In embodiments, the request to move the UI element may include a click and hold of the input mechanism (e.g., a click and hold of a mouse, stylus, etc.). 
     At block  1310 , the system, in response to determining that the request meets a movement criteria, displays the UI element at a third position within the CGR environment. In embodiments, the third position may be different from the first position and the second position. In embodiments, the third-position may be a lead-in location, as described above, within the CGR environment. 
     In embodiments, displaying the UI element at the third position within the CGR environment may include teleporting the UI element from the first position to the third position. For example, displaying the UI element at the third position may include displaying the UI element at the third position while simultaneously, or near-simultaneously, ceasing to display the UI element at the first position. The effect is that the UI element seems to teleport from the first position to the third position. 
     In embodiments, determining that the request meets the movement criteria may include determining that the user&#39;s gaze has been detected as directed to the second position, has been detected as dwelling on the second position or a UI element in the second position for at least a predetermined period of time, and/or has been detected as directed to a particular UI element in the second position. 
     In embodiments, determining that the request meets the movement criteria may further include determining that the movement distance of the input mechanism exceeds a threshold amount of movement. If the input mechanism movement distance exceeds the threshold amount of movement, the request to move the UI element may be determined to meet the movement criteria. Conversely, if the input mechanism movement distance does not exceed the threshold amount of movement, the request to move the UI element may be determined not to meet the movement criteria. 
     In embodiments, determining that the request meets the movement criteria may further include determining that the movement direction of the input mechanism is in a particular direction. If the movement direction of the input mechanism is determined to be towards the second position, the request to move the UI element may be determined to meet the movement criteria. Conversely, if the movement direction of the input mechanism is determined to be not towards the second position, the request to move the UI element may be determined not to meet the movement criteria. 
     In embodiments, determining that the request meets the movement criteria may further include determining that the current gaze of the user is directed to a particular type of application. If the application at which the gaze of the user is directed is determined to be of a particular type, the request to move the UI element may be determined to meet the movement criteria. Conversely, if the application at which the gaze of the user is directed is not determined to be of the particular type, the request to move the UI element may be determined not to meet the movement criteria. 
     At block  1312 , the system, in response to displaying the UI element at the third position, moves, in accordance with the request, the UI element to the second position. In aspects, moving the UI element from the third position to the second position may include sliding, dragging, and/or otherwise moving the UI element from the third position to the second position such that the UI element seems to move (instead of teleport) from the third position to the second position. 
     In embodiments, moving the UI element from the third position to the second position may include animating the move. The animation may be such that a user may perceive that the UI element  1210  slides, drags, and/or otherwise moves (instead of teleport) from the third position to the second position. 
     As described above, one aspect of the present technology is the gathering and use of data available from various sources to provide specialized resource management of low-power devices (e.g., HMD devices) to conserve battery life for users and to provide specialized content to users of the low-power devices. The present disclosure contemplates that, in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, twitter IDs, home addresses, data or records relating to a user&#39;s health or level of fitness (e.g., vital signs measurements, medication information, exercise information, etc.), date of birth, or any other identifying or personal information. 
     The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to conserve battery life of a user&#39;s low-power device. Accordingly, for example, the use of such personal information data the system to properly manage resources to conserve battery life for the low-power devices. Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. For instance, health and fitness data may be used to provide insights into a user&#39;s general wellness or may be used as positive feedback to individuals using technology to pursue wellness goals. 
     The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should occur after receiving the informed consent of the users. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of or access to certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country. 
     Despite the foregoing, the present disclosure also contemplates examples in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of managing resources for low-powered devices, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. In another example, users can select not to provide eye-tracking data, such as pupil location, pupil dilation, and/or blink rate for specialized resource management. In yet another example, users can select to limit the length of time the eye-tracking data is maintained or entirely prohibit the development of a baseline eye tracking profile. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app. 
     Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health-related applications, data de-identification can be used to protect a user&#39;s privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount and/or the specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods. 
     Therefore, although the present disclosure broadly covers the use of personal information data to implement one or more various disclosed examples, the present disclosure also contemplates that the various examples can also be implemented without the need for accessing such personal information data. That is, the various examples of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, resources of low-powered devices can be managed, and content (e.g., status updates and/or objects) can be selected and delivered to users by inferring preferences based on non-personal information data or a bare minimum amount of personal information, such as the content being requested by the device associated with a user, other non-personal information available to the system controlling the low-power device, or publicly available information.
