Portal Views for Content Items

Abstract

Various implementations disclosed herein include devices, systems, and methods for providing an XR environment that represents an environment with a viewing portal for viewing additional content items disposed behind the viewing portal. Some implementations determine a first position of the viewing portal in a 3D coordinate system that corresponds to the environment, determine a second position of the content item in the 3D coordinate system, the second position being opposite the front of the viewing portal, and determine a viewpoint of the electronic device in the 3D coordinate system. In some implementations, a portion of the content item that is visible through the viewing portal from a viewpoint is identified, the portion being identified based on the first position, the second position, and the viewpoint. A view of the identified portion of the content item is then provided in the environment.

Description

[Technical Field]

[0001] The present disclosure relates generally to electronic devices that display virtual content, and more particularly to systems, methods, and devices that provide views of virtual content in a physical environment. [Background technology]

[0002] Augmented reality (XR) environments provide views that combine real and virtual content in various ways. For example, an XR environment can include views that include virtual content items that correspond to two-dimensional (2D) photographs viewed within the real physical environment. Existing systems and techniques may not display such virtual content in a manner that adequately distinguishes the virtual content from the surrounding physical environment. For example, a 2D photograph may be displayed such that its edges are not easily distinguishable from the surrounding physical environment, or such that portions of the virtual content appear to extend through boundaries / walls of the physical environment. Improved techniques are needed for providing views of XR environments with virtual 2D photographs within the physical environment. Summary of the Invention

[0003] Various implementations disclosed herein include devices, systems, and methods that provide a view of an XR environment, including a physical environment with a viewing portal for viewing additional virtual content items positioned at a distance behind the viewing portal. For example, a panoramic photograph may be textured onto a virtual curved surface that is a calculated distance, such as 10 meters, behind the viewing portal. In some implementations, placing a content item behind the viewing portal can provide a desirable appearance, for example, that better distinguishes the content item from the physical environment at the edges of the viewing portal. In some implementations, multiple viewing portals for different content items may be presented simultaneously, and selection of one of the content items may trigger the provision of an expanded viewing portal for the selected content item. Alternatively, multiple viewing portals may show the same content item, for example, to allow comparison of different imaging effects applied to the same content item.

[0004] In general, one innovative aspect of the subject matter described herein can be implemented in a method that includes determining a first position of a viewing portal within a 3D coordinate system corresponding to an environment and determining a second position of a content item within the 3D coordinate system, the second position being opposite the front of the viewing portal. A viewpoint of an electronic device is then determined within the 3D coordinate system. In some implementations, a portion of the content item visible through the viewing portal from a viewpoint is identified, the portion being identified based on the first position, the second position, and the viewpoint. A view of the identified portion of the content item within the environment is then provided.

[0005] The present disclosure may have a more detailed description, as can be understood by those skilled in the art, by reference to aspects of several exemplary implementations, some of which are illustrated in the accompanying drawings. [Brief explanation of the drawings]

[0016] According to common practice, the various features illustrated in the figures may not be drawn to scale. Accordingly, dimensions of various features may be arbitrarily increased or decreased for clarity. In addition, some drawings may not depict all of the components of a given system, method, or device. Finally, like reference numerals may be used throughout the specification and figures to indicate like features.

[0017] Numerous details have been described to provide a thorough understanding of the exemplary implementations shown in the drawings. However, the drawings merely illustrate some exemplary aspects of the present disclosure and therefore should not be considered limiting. Those skilled in the art will understand that other effective aspects or variations do not include all of the specific details described herein. Furthermore, well-known systems, methods, components, devices, and circuits have not been described in exhaustive detail so as not to obscure more pertinent aspects of the exemplary implementations described herein.

[0018] Various implementations disclosed herein include devices, systems, and methods that provide a view of an XR environment including a depiction of a physical environment having a viewing portal for viewing additional content items located behind the viewing portal (e.g., opposite the front of the viewing portal). In some implementations, the viewing portal is a virtual 2D plane (e.g., a planar area bounded by a rounded rectangle). In some implementations, the additional content items are displayed using a surface located a predetermined distance (e.g., 10 meters or some other distance) behind the viewing portal. For example, a 2D panoramic picture may be textured onto a vertically flat, horizontally curved surface 10 meters behind the viewing portal and centered on the viewing portal.

[0019] Placing additional content items at a distance behind the viewing portal allows the user of the electronic device to focus on depth beyond the viewing portal window. Displacement of content behind the portal may make the distinction between the content viewed at the edge of the portal and the surrounding environment more apparent. Displacement of content behind the portal may also provide the appearance of depth between the portal and the virtual content and / or within the 2D virtual content itself. Virtual content may include 2D pictures, 2D images, 2D panoramas, etc.

[0020] The viewing portal configuration may be determined based on the content being viewed through it and / or the physical environment, hi some implementations, the shape and / or size of the viewing portal is controlled such that the viewing portal displayed within the physical environment does not intersect with the physical boundaries (e.g., walls, ceiling, floor) of the physical environment.

[0021] 1 shows a user 120 using an electronic device 180 in a physical environment 105, which in this example is a room in a house or an office. The electronic device 180 presents an XR environment.

[0022] As shown in FIG. 1 , the display 110 of the electronic device 180 presents an XR environment that includes a 2D photograph (e.g., a panoramic photograph) as virtual content 140 within a representation 130 of the physical environment 105. The virtual content 140 appears to float within the physical environment 105. However, the 2D panoramic photograph 140 displayed at the correct scale occludes an undesirably large portion of the representation of the physical environment 105, in this case obscuring the physical environment 105 because portions 140 a, 140 b of the virtual content 140 extend beyond the walls of the physical environment 105. In some cases, the virtual content 140 can cover other user interfaces or virtual content presented in the XR environment. This can occur particularly when viewing multiple large virtual content items, such as the 2D panoramic photograph 140, in the physical environment 105.

[0023] Thus, in some implementations, the virtual content and the physical or virtual environment are separated using a viewing portal (e.g., a user interface). For example, the viewing portal can be a 2D plane (e.g., a planar area bounded by a rounded rectangle) within the physical or virtual environment that serves as a portal to the 3D virtual environment. Included within that virtual environment can be a surface oriented toward the viewing portal and positioned at a predetermined depth (e.g., 10 meters or some other distance) behind the viewing portal to display the virtual content with the appearance of depth in the 3D virtual environment. The distance at which the virtual content (e.g., a 2D photograph) is positioned behind the viewing portal is selected to give the viewer (e.g., eyes / brain) the illusion that the photographed scene is true to scale; in other words, the illusion that the person is looking out a window in a real landscape or real environment. People can judge distance (in part) by the vergence angle of their eyes; once a person's object of focus is past a few meters, their brain can no longer distinguish actual depth from vergence of the eyes (e.g., they are said to be focusing at "infinity" at that point). In this case, secondary considerations in the presentation (e.g., geometry, relative size, shadows, etc.) can provide alternative hints at depth using a separate viewing portal and virtual content placement on the surface behind the viewing portal.

[0024] In some implementations, the virtual content includes a 2D photograph, a 2D panoramic photograph, or a 2D depth-separated photograph. The 2D depth-separated photograph may include at least one portion (e.g., a subject of the photograph) having a first depth and a second portion (e.g., a background) having a second depth greater than the first depth.

[0025] 2 illustrates virtual content displaced behind and viewed through an exemplary viewing portal. As shown in FIG. 2, display 110 of electronic device 180 displays textured virtual content 140 on surface 260 that is vertically flat and horizontally curved to be 10 meters (e.g., a preset distance) behind viewing portal 250. In some examples, surface 260 may comprise a full or partial cylindrical shell centered at viewing portal 250. In FIG. 2, virtual content 140 displayed behind viewing portal 250 has a focal length that is different from and greater than the distance to viewing portal 250.

[0026] In some implementations, virtual content 140 is positioned behind viewing portal 250 to give the appearance of depth when viewed through viewing portal 250 in physical environment 105. As shown in FIG. 2 , as electronic device 180 moves within physical environment 105, the portion of virtual content 140 visible through viewing portal 250 changes according to the changing perspective of electronic device 180. For example, as electronic device 180 moves left in physical environment 105, additional areas to the right of virtual content 140 become visible through fixed viewing portal 250. It should be understood that virtual content 140 on surface 260 may only be viewable through viewing portal 250. For example, if a user moves to the side or behind viewing portal 250 in representation 130 of physical environment 105, neither virtual content 140 nor surface 260 will be visible behind viewing portal 250.

[0027] In some implementations, the initial position of the viewing portal 250 relative to the representation 130 of the physical environment 105 in the XR environment is a default position in front of and oriented toward the electronic device 180. For example, the initial position of the viewing portal 250 may be 3 feet in front of the electronic device 180, facing the electronic device 180, and 5 feet above the floor (e.g., ground surface) of the physical environment 105. In some implementations, the initial size and shape of the viewing portal 250 is determined by an application running and displaying the corresponding virtual content behind and visible through the viewing portal 250. In some implementations, the viewing position of the viewing portal 250 relative to the physical environment 105 is manually controlled and can be moved by the user 120 of the electronic device 180.

[0028] In some implementations, the initial position of the virtual content 140 is oriented (e.g., centered) toward the viewing portal 250. In some implementations, the horizon or horizon line shown in the surface 260 behind the viewing portal 250 or in the virtual content 140 is aligned with the horizon or horizon line of the physical environment 105 or other viewing environment. Such alignment may be achieved by tracking the position and orientation of the device 180 within the physical environment, identifying the location of the horizon line based on the orientation and position of the device 180, identifying the horizon line shown in the 2D content (e.g., based on image analysis or metadata such as capture information associated with the capture of the 2D content), and aligning the horizon line when placing the 2D content relative to a representation of the physical environment. In some implementations, the ground plane shown in the surface 260 behind the viewing portal 250 or in the virtual content 140 is aligned with the ground plane of the physical environment 105 or other viewing environment. In some implementations, the placement and shape of surface 260 is determined by an application running and displaying corresponding virtual content on surface 260 that is viewed through a corresponding viewing portal. In some implementations, physical environment 105 or other viewing environment may not include other surfaces or content.

[0029] In some implementations, virtual content is positioned behind and not suitable to be viewed through a corresponding viewing portal based on the depth (e.g., focal length) included in the virtual content. For example, it may be undesirable to use a panorama created with objects close to the capturing image sensor because stereo capture may result in a noticeable difference between left-eye and right-eye capture, which may result in visual discomfort when viewed through the viewing portal.

[0030] 3A illustrates separate virtual content positioned behind and viewed through multiple exemplary viewing portals. As shown in FIG. 3A, display 110 illustrates a panoramic 2D photograph as virtual content 340-1 viewed through viewing portal 350-1, virtual content 140 viewed through viewing portal 350-2, and a panoramic 2D photograph as virtual content 340-3 viewed through viewing portal 350-3. Virtual content 340-1 is a rocky hill, virtual content 140 is a rocky shore of a lake, and virtual content 340-3 is a sunrise over the water. In some implementations, the portions of virtual content 340-1, 140, and 340-3 visible through viewing portals 350-1, 350-2, and 350-3 are displayed on different corresponding surfaces displaced behind each respective viewing portal 350-1, 350-2, and 350-3. Surfaces and associated virtual content can only be viewed through their respective viewing portals (e.g., virtual content 340-1 can be viewed through viewing portal 350-1, but not through viewing portals 350-2 and 350-3). In some implementations, corresponding surfaces can be positioned to have a common focal length based on the characteristics (e.g., size, capture parameters, object size, shape, etc.) of the respective virtual content 340-1, 340-2, 340-3. In some implementations, corresponding surfaces can be centered around and displaced behind each respective viewing portal. In other words, corresponding surfaces can be located in different locations when placed within the same virtual environment, but can partially overlap.

[0031] As shown in FIG. 3B , the portions of virtual content 340-1, 140, 340-3 visible through viewing portals 350-1, 350-2, 350-3 may be displayed on the same surface 260 or on different surfaces located at the same location. Therefore, the focal lengths of the virtual content 340-1, 140, 340-3 may be the same. The focal lengths of the virtual content 340-1, 140, 340-3 may be different from and greater than the distances to the viewing portals 350-1, 350-2, 350-3. For example, a common focal length allows user 120 to easily switch their attention between the individual pieces of virtual content 340-1, 140, 340-3 within physical environment 105. In some implementations, viewing portals 350-1, 350-2, 350-3 have a common shape and size. In some implementations, viewing portals 350-1, 350-2, 350-3 are different sizes but maintain a common shape, which allows user 120 to better recognize and distinguish virtual content 340-1, 140, 340-3 from physical environment 105. In some implementations, viewing portals 350-1, 350-2, 350-3 have rounded corners, which may further allow user 120 to distinguish the 3D virtual environment viewed through viewing portals 350-1, 350-2, 350-3 from the physical environment 105 viewed around viewing portals 350-1, 350-2, 350-3. The rounded corners on viewing portals 350-1, 350-2, 350-3 may use the same radius for the curved corners. In some implementations, the viewing portals 350-1, 350-2, 350-3 have edges with perceptible depth. In some implementations, the edge effects of the viewing portals 350-1, 350-2, 350-3 enable consistent or desired lighting effects to be provided with respect to the virtual content and lighting effects in the viewing portals (e.g., light spilling from the viewing portals).

[0032] 3C , portions of virtual content 340-1, 140, 340-3 viewable through viewing portals 350-1, 350-2, 350-3 can be displayed on different surfaces 360-1, 360-2, 360-3 located in the same or different XR environments. In some implementations, when different virtual content 340-1, 140, 340-3 are located on different respective surfaces 360-1, 360-2, 360-3 behind corresponding viewing portals 350-1, 350-2, 350-3 that are viewed simultaneously in a physical or virtual environment, the different respective surfaces 360-1, 360-2, 360-3 can be determined such that the respective focal lengths of the viewable portions of the different virtual content 340-1, 140, 340-3 are similar to each other and are all different from the distances from user 120 to the viewing portals 350-1, 350-2, 350-3.

[0033] In some implementations, the design of a viewing portal (e.g., size, shape, aspect ratio, depth, animation, etc.) is determined by the application running and / or displaying the corresponding virtual content behind and viewed through the viewing portal. Separating the viewing portal from the virtual content viewed through the corresponding viewing portal but displayed behind it allows the design of the corresponding viewing portal to be changed (e.g., expanded, stretched, or animated) without modifying the virtual content. In some implementations, the corresponding viewing portal always covers the edges of the virtual content viewed through it. For example, the viewing portal can change (e.g., size, shape, etc.) based on the virtual content viewed through it to prevent visible gaps between the corresponding viewing portal and the viewed virtual content no matter where user 120 moves within physical environment 105. In some implementations, the corresponding viewing portal is removed from physical environment 105 to prevent visible gaps between the corresponding viewing portal and the viewed virtual content. In some implementations, the placement (eg, display size) of the virtual content behind the viewing portal is based on the original size and physical environment 105 of the virtual content or representations therein.

[0034] FIG. 3D illustrates a selected virtual content item being viewed through an exemplary expanded viewing portal displaced behind it. As shown in FIG. 3A, when virtual content 140 is selected by user 120, viewing portal 350-2 can be expanded and stretched so that more of 2D panoramic photograph 140 is visible to user 120. As shown in FIG. 3D, when virtual content 140 is selected by user 120 in FIG. 3B, all 180 degrees of 2D panoramic photograph 140 is visible to user 120 on surface 260 through expanded viewing portal 350-2′ within physical environment 105. In this case, viewing portal 350-2′ can provide the visual effect of user 120 entering a virtual environment behind viewing portal 350-2 shown in FIGS. 3A-3C. In some implementations, there are other types of effects (e.g., audio, etc.) that can be applied based on which virtual content 340-1, 140, 340-3 is selected and where the corresponding viewing portal is positioned relative to physical environment 105.

[0035] In some implementations, if the 2D panoramic photograph 140 included 360 degrees when it was created, the 360-degree virtual content 140 can be viewed as the user 120 rotates 360 degrees within the physical environment 105 through a viewing portal 350-2′ that can frame a spherically shaped surface displayed within the physical environment 105 with the top and bottom removed. Additionally, the virtual content displayed behind the corresponding viewing portal can include orientations other than horizontal. For example, the panorama can be oriented vertically, such as at a 30-degree or 45-degree angle.

[0036] 4 illustrates virtual content displaced behind and viewed through multiple exemplary viewing portals. As shown in FIG. 4, display 110 shows virtual content 140 as seen by user 120 through multiple viewing portals 450-1, 450-2, 450-3, and 450-4. Virtual content 140 includes a rocky shore of a lake, a portion of the lake, and clouds in the distance above the lake. In some implementations, virtual content 140 is displayed on a single 2D surface that extends behind viewing portals 450-1, 450-2, 450-3, and 450-4, with different portions of virtual content 140 being visible through each of viewing portals 450-1, 450-2, 450-3, and 450-4 based on the perspective of electronic device 180 within physical environment 105. As shown in FIG. 4, when viewed by a user 120 at viewing portals 450-1, 450-2, 450-3, 450-4 in physical environment 105, virtual content 140 is displayed on a flat 2D plane behind viewing portals 450-1, 450-2, 450-3, 450-4, respectively.

[0037] As shown in FIG. 4 , each of viewing portals 450-1, 450-2, 450-3, and 450-4 applies different artistic effects to the same 2D panoramic image 140 viewed by user 120 through the portal. For example, the different visual effects can include, but are not limited to, vibrant warm hues, silver tones, monochrome tones, cool hues, effects that emphasize natural light, etc. Visual effects can make the virtual content appear more sketch-like or painting-like and can adjust clarity, color, brightness, or contrast. In this way, viewing portals 450-1, 450-2, 450-3, and 450-4 provide a tangible way for user 120 to simultaneously view virtual content 140 through different simulations of visual effects.

[0038] FIG. 5 illustrates virtual content displaced behind and viewed through another exemplary viewing portal. For example, the placement of the virtual content in the virtual environment behind the corresponding viewing portal (e.g., entered through) can be based on characteristics of the virtual content. In some implementations, the characteristics of the virtual content include the orientation or movement of the capturing electronic device when the virtual content was created. In some implementations, the gravity vector and other sensor data of the capturing electronic device can be used to determine the placement of the virtual content behind the corresponding viewing portal (e.g., the horizon, the ground plane, the pose of objects therein, etc.). In some implementations, image analysis of the virtual content can be used to determine the placement of the virtual content behind the corresponding viewing portal in the physical environment (e.g., the horizon, the ground plane, the pose of objects therein, etc.).

[0039] As shown in FIG. 5 , user 120 views virtual content 540 positioned behind a viewing portal 550 in a representation of physical environment 105 using the same orientation as the creator of the virtual content 540. In some implementations, the horizon of the virtual content 540 coincides with the horizon of the physical environment 105. In FIG. 5 , the skyscraper in the virtual content 540 may be displayed on a flat 2D surface oriented toward the viewing portal 550 and curved to be 10 meters behind and above the viewing portal 550. For example, the virtual content 540 may be displayed on a surface 260 rotated 90 degrees to have a vertical orientation relative to the portal 540 in the physical environment 105. However, the placement is not intended to be so limited, and other implementations may provide placement of the virtual content 540 behind the viewing portal 550 in the physical environment 105 that maintains or replicates the capture orientation. For example, the virtual content 540 can be displayed on intersecting orthogonal planes positioned behind the viewing portal 550, a first vertical plane parallel to the far wall of the physical environment 105 and a second horizontal plane parallel to the ceiling.

[0040] Figure 6A illustrates virtual content viewed through yet another exemplary viewing portal positioned behind it. As shown in Figure 6A, user 120 views virtual content 640 positioned behind viewing portal 650 in physical environment 105. In Figure 6A, virtual content 640 is a 2D depth-separated photograph that includes an isolated object 640a having a first depth and an isolated background 640b having a second depth that is greater than the first depth.

[0041] FIG. 6B shows a subsequent view of the depth-separated object 640a of the virtual content 640 moved in front of and aligned with the depth-separated background 640b that remains viewed by the user 120 through the modified viewing portal 650′ in the physical environment 105. As shown in FIG. 6B, the ground plane 660 of the background 640b of the virtual content 640′ is expanded such that the object 640a appears in front of and separated from the background 640b on the ground plane 660. In some implementations, the modified viewing portal 650′ has a size based on the size of the object 640a of the virtual content 640′. In some implementations, the virtual content 640′ is a 3D virtual object in the physical environment 105. In some implementations, the virtual content 640′ is aligned within the physical environment 105 (e.g., on a flat surface such as a ground plane, floor, desktop, or tabletop). As shown in FIG. 6B, the virtual content 640′ is aligned with the top surface of a box 670. In some implementations, the objects 640a of the virtual content 640' are aligned to different characteristics (horizon lines, distinctive features, etc.) of the background 640b of the virtual content 640'.

[0042] In some implementations, the virtual content 640 and viewing portal 650 move as animated objects between the arrangement shown in Figure 6A and the subsequent configuration shown in Figure 6B. In some implementations, text can be added that has a spatial relationship to the view of the virtual content 640' shown in Figure 6B. In some implementations, visual effects (e.g., smoke, lightning, celebratory effects, etc.) can be added that have a spatial relationship to the arrangement of the virtual content 640' shown in Figure 6B. In some implementations, audio effects (e.g., point source, ambience, spatial audio, etc.) can be added that have a spatial relationship to the view of the virtual content 640' shown in Figure 6B.

[0043] FIG. 7 is a flowchart illustrating an example method for providing a view of an XR environment showing a physical or virtual environment using a viewing portal for viewing additional content items placed behind the viewing portal. For example, a panoramic photograph may be textured onto a virtual curved surface that is, for example, 10 meters behind the viewing portal. In some implementations, placing the content items behind the viewing portal can provide a desirable appearance, for example, to better distinguish the content items from the physical environment at the edges of the viewing portal and / or give the viewer the sense of viewing an image with depth. In some implementations, method 700 is performed by a device (e.g., electronic device 800 of FIG. 8 ). Method 700 can be performed using an electronic device or by multiple devices in communication with each other. In some implementations, method 700 is performed by processing logic, which includes hardware, firmware, software, or a combination thereof. In some implementations, method 700 is performed by a processor executing code stored in a non-transitory computer-readable medium (e.g., memory). In some implementations, method 700 is performed by an electronic device having a processor.

[0044] At block 710, method 700 determines a first position of the viewing portal within a 3D coordinate system corresponding to the environment (e.g., the physical environment or the virtual environment). In some implementations, the initial position of the viewing portal is a pre-defined location (e.g., centered) based on the physical environment or the 3D coordinate system. In some implementations, the initial position of the viewing portal is based on depth data and / or other sensor data acquired about the physical environment. In some implementations, an initial size and / or aspect ratio of the viewing portal may also be determined.

[0045] At block 720, method 700 determines a second position of the content item within the 3D coordinate system, the second position being opposite the front of the viewing portal. In some implementations, the second position is selected at a focal distance behind the first position such that the view of the additional content item from both eyes of a person is substantially the same (e.g., there is little or no parallax). For example, the additional content item may be placed 10 meters behind the viewing portal and centered within the viewing portal. In some implementations, the content item includes a depth-segmented image, a 2D photograph, or a 2D panoramic photograph. In some implementations, determining the second position may also involve identifying a surface, e.g., a flat surface or a curved flat surface, that textures the content item. The display size of an image corresponding to the content item on a surface object may be based on the original size of the content item or a depiction therein.

[0046] In some implementations, the second position is independent of the first position at block 720, so the viewing portal can be expanded, stretched, or animated without modifying the content item. In some implementations, the second position is selected to provide the appearance of depth to the content item.

[0047] In some implementations, the second position aligns the content item with respect to the environment or 3D coordinate system at block 720. The alignment of the content item at the second position may be determined using sensor data (e.g., orientation, motion, gravity vectors, etc.) from the electronic device that created the content item. In some implementations, the second position aligns image features (e.g., horizon lines) corresponding to the content item on the surface object with features (e.g., horizon lines) of the environment.

[0048] At block 730, the method 700 generates a surface object, the surface object textured with an image corresponding to the content item, the surface object positioned at a second position. In some implementations, the content item is a panoramic photograph, and the surface object includes a virtual curved surface that is a distance behind the viewing portal. In some implementations, the image corresponding to the content item includes a 2D image corresponding to the content item. In some implementations, the surface object includes a portion of a cylindrical shell, and the interior surface of the cylindrical shell is textured with an image corresponding to the content item.

[0049] At block 740, the method 700 determines a viewpoint of the electronic device within a 3D coordinate system. In some implementations, the viewpoint of the electronic device is determined based on sensor data of the electronic device. In some implementations, the viewpoint of the electronic device is determined relative to the physical environment. In some implementations, the initial position of the viewing portal is a set distance directly in front of the viewpoint.

[0050] At block 750, the method 700 identifies a portion of the surface object that is visible through the viewing portal from the viewpoint, the portion being identified based on the first position, the second position, and the viewpoint. In some implementations, the size, aspect ratio, or first position of the viewing portal is determined based on parameters of an application that is running when the surface object is viewed and / or characteristics of the content item being viewed.

[0051] At block 760, the method 700 provides a view of the identified portion of the surface object in the environment. In some implementations, the identified portion of the surface content changes as the viewpoint of the electronic device moves within the physical environment. For example, the identified portion may be the subject of a content item.

[0052] In some implementations, the viewing portal can distinguish the content item from the physical environment (e.g., using the edges of the viewing portal). The viewing portal may also distinguish the surface object from the environment using the edges of the viewing portal. In some implementations, the size of the viewing portal is smaller than the physical environment, and the identified portion of the surface object does not intersect with an enclosing surface, such as a wall, of the physical environment.

[0053] In some implementations, different content items are placed behind corresponding multiple viewing portals that can be viewed simultaneously in a physical or virtual environment, and the focal lengths of the viewable portions of the different content items are determined to be similar to each other and different from the distances to the multiple viewing portals in the physical or virtual environment. In some implementations, multiple viewing portals for different content items may be viewed simultaneously, and selecting one of the content items may provide an expanded viewing portal such that more of the selected content item is visible in the physical environment. Alternatively, multiple viewing portals for the same content item can be used to enable comparison of different imaging effects applied to the same content item.

[0054] The method 700 may include providing a view of a plurality of viewing portals corresponding to a plurality of different content items in an environment, the plurality of viewing portals including the viewing portal and the plurality of content items including the content items. The plurality of content items may be provided on a plurality of surface objects at consistent focal distances behind corresponding viewing portals of the plurality of viewing portals. In accordance with a selection of one of the plurality of content items, a size of a corresponding one of the plurality of viewing portals may be expanded.

[0055] In some implementations, the content item includes a first portion with a first depth and a second portion with a second, greater depth. Then, while a portion of the surface object corresponding to the second portion remains visible, the viewing portal is reduced in size, and the first portion is moved to a position on the ground surface in front of the reduced-size viewing portal while simultaneously changing the first portion to a corresponding size.

[0056] In some implementations, blocks 710 to 760 are executed repeatedly. In some implementations, the techniques disclosed herein may be implemented on a wearable device such as an HMD having an optical see-through or opaque display.

[0057] While the examples provided above describe the use of a viewing portal in a physical environment, it should be understood that the viewing portal may also be used to view content in a virtual environment to provide similar benefits.
