The present disclosure generally relates to systems, methods, and devices for displaying, on a first device, content rendered by a second device.
In various implementations, a first device generates content to be rendered on a second device. It may be desirable to reduce the bandwidth used in transmitting the content from the first device to the second device.
So that the present disclosure can be understood by those of ordinary skill in the art, a more detailed description may be had by reference to aspects of some illustrative implementations, some of which are shown in the accompanying drawings.
In accordance with common practice the various features illustrated in the drawings may not be drawn to scale. Accordingly, the dimensions of the various features may be arbitrarily expanded or reduced for clarity. In addition, some of the drawings may not depict all of the components of a given system, method or device. Finally, like reference numerals may be used to denote like features throughout the specification and figures.
Various implementations disclosed herein include devices, systems, and methods for distributed content rendering. In various implementations, the method is performed by a first device including a display, one or more processors, and non-transitory memory. The method includes determining a pose of a virtual object in a volumetric environment. The method includes generating a request for content rendering instructions based on the pose of the virtual object. The method includes sending, to a second device, the request for the content rendering instructions. The method includes receiving, from the second device, the content rendering instructions. The method includes displaying, based on the content rendering instructions, a content rendering on the virtual object.
In accordance with some implementations, a device includes one or more processors, a non-transitory memory, and one or more programs; the one or more programs are stored in the non-transitory memory and configured to be executed by the one or more processors. The one or more programs include instructions for performing or causing performance of any of the methods described herein. In accordance with some implementations, a non-transitory computer readable storage medium has stored therein instructions, which, when executed by one or more processors of a device, cause the device to perform or cause performance of any of the methods described herein. In accordance with some implementations, a device includes: one or more processors, a non-transitory memory, and means for performing or causing performance of any of the methods described herein.
People may sense or interact with a physical environment or world without using an electronic device. Physical features, such as a physical object or surface, may be included within a physical environment. For instance, a physical environment may correspond to a physical city having physical buildings, roads, and vehicles. People may directly sense or interact with a physical environment through various means, such as smell, sight, taste, hearing, and touch. This can be in contrast to an extended reality (XR) environment that may refer to a partially or wholly simulated environment that people may sense or interact with using an electronic device. The XR environment may include virtual reality (VR) content, mixed reality (MR) content, augmented reality (AR) content, or the like. Using an XR system, a portion of a person's physical motions, or representations thereof, may be tracked and, in response, properties of virtual objects in the XR environment may be changed in a way that complies with at least one law of nature. For example, the XR system may detect a user's head movement and adjust auditory and graphical content presented to the user in a way that simulates how sounds and views would change in a physical environment. In other examples, the XR system may detect movement of an electronic device (e.g., a laptop, tablet, mobile phone, or the like) presenting the XR environment. Accordingly, the XR system may adjust auditory and graphical content presented to the user in a way that simulates how sounds and views would change in a physical environment. In some instances, other inputs, such as a representation of physical motion (e.g., a voice command), may cause the XR system to adjust properties of graphical content.
Numerous types of electronic systems may allow a user to sense or interact with an XR environment. A non-exhaustive list of examples includes lenses having integrated display capability to be placed on a user's eyes (e.g., contact lenses), heads-up displays (HUDs), projection-based systems, head mountable systems, windows or windshields having integrated display technology, headphones/earphones, input systems with or without haptic feedback (e.g., handheld or wearable controllers), smartphones, tablets, desktop/laptop computers, and speaker arrays. Head mountable systems may include an opaque display and one or more speakers. Other head mountable systems may be configured to receive an opaque external display, such as that of a smartphone. Head mountable systems may capture images/video of the physical environment using one or more image sensors or capture audio of the physical environment using one or more microphones. Instead of an opaque display, some head mountable systems may include a transparent or translucent display. Transparent or translucent displays may direct light representative of images to a user's eyes through a medium, such as a hologram medium, optical waveguide, an optical combiner, optical reflector, other similar technologies, or combinations thereof. Various display technologies, such as liquid crystal on silicon, LEDs, uLEDs, OLEDs, laser scanning light source, digital light projection, or combinations thereof, may be used. In some examples, the transparent or translucent display may be selectively controlled to become opaque. Projection-based systems may utilize retinal projection technology that projects images onto a user's retina or may project virtual content into the physical environment, such as onto a physical surface or as a hologram.
Numerous details are described in order to provide a thorough understanding of the example implementations shown in the drawings. However, the drawings merely show some example aspects of the present disclosure and are therefore not to be considered limiting. Those of ordinary skill in the art will appreciate that other effective aspects and/or variants do not include all of the specific details described herein. Moreover, 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 example implementations described herein.
In various implementations, a first device generates content to be rendered on a second device. For example, in various implementations, the first device transmits, to the second device, content rendering instructions interpretable by the second device to generate a content rendering. In various implementations, the content rendering instructions include an image or video stream that the second device renders on a virtual object, such as a virtual picture frame or virtual television. To advantageously reduce the amount of bandwidth in transmitting the content rendering instructions from the first device to the second device, the first device generates the content rendering instructions based on a pose of the virtual object. For example, when the user is close to the virtual picture frame and the image will be rendered by the second device at a first size, the image transmitted by the first device has a first resolution. When the user is far from the virtual picture frame and the image will be rendered by the second device at a second size smaller than the first size, the image transmitted by the first device has a second resolution lower than the first resolution. As another example, when the virtual picture frame is at first angle to the user (e.g., facing the user) and the image will be rendered by the second device with a first width, the image transmitted by the first device has a first horizontal resolution. When the virtual picture frame is at a second angle to the user (e.g., rotated about a vertical axis of the virtual picture frame such that the virtual picture frame is partially turned away from the user) and the image will be rendered by the second device with a second width less than the first width, the image transmitted by the first device has a second horizontal resolution lower than the first horizontal resolution.
Further, in various implementations, the content rendering instructions include graphic commands. For example, rather than transmit an image of a text field populated with particular text, the content rendering instructions include the particular text and a graphic command to render a text field populated with the particular text.

In some implementations, the electronic device 120 includes a suitable combination of software, firmware, and/or hardware.

As such, in some implementations, the user holds the electronic device 120 in his/her hand(s). In some implementations, while providing XR content, the electronic device 120 is configured to display an XR object (e.g., an XR cylinder 109) and to enable video pass-through of the physical environment 105 (e.g., including a representation 117 of the table 107) on a display 122. The electronic device 120 is described in greater detail below with respect to
According to some implementations, the electronic device 120 provides an XR experience to the user while the user is virtually and/or physically present within the physical environment 105.
In some implementations, the user wears the electronic device 120 on his/her head. For example, in some implementations, the electronic device includes a head-mounted system (HMS), head-mounted device (HMD), or head-mounted enclosure (HME). As such, the electronic device 120 includes one or more XR displays provided to display the XR content. For example, in various implementations, the electronic device 120 encloses the field-of-view of the user. In some implementations, the electronic device 120 is a handheld device (such as a smartphone or tablet) configured to present XR content, and rather than wearing the electronic device 120, the user holds the device with a display directed towards the field-of-view of the user and a camera directed towards the physical environment 105. In some implementations, the handheld device can be placed within an enclosure that can be worn on the head of the user. In some implementations, the electronic device 120 is replaced with an XR chamber, enclosure, or room configured to present XR content in which the user does not wear or hold the electronic device 120.

Although the data obtaining unit 342, the rendering requesting unit 344, the XR presenting unit 346, and the data transmitting unit 348 are shown as residing on a single device (e.g., the electronic device 120), it should be understood that in other implementations, any combination of the data obtaining unit 342, the rendering requesting unit 344, the XR presenting unit 346, and the data transmitting unit 348 may be located in separate computing devices.
Moreover,
The XR environment 400 includes a plurality of objects, including one or more real objects (e.g., a wall 411, a picture 412, a table 413, and a phone 414) and one or more virtual objects (e.g., a virtual clock 421 and a virtual cylinder 422). In various implementations, certain objects (such as the real objects 411, 412, 413, and 414 and the virtual cylinder 422) are displayed at a location in the XR environment 400, e.g., at a location defined by three coordinates in a three-dimensional (3D) XR coordinate system. Accordingly, when the electronic device moves in the XR environment 400 (e.g., changes position and/or orientation), the objects are moved on the display of the electronic device, but retain their location in the XR environment 400. Such virtual objects that, in response to motion of the electronic device, move on the display, but retain their position in the XR environment 400 are referred to as world-locked objects. In various implementations, certain virtual objects (such as the virtual clock 421) are displayed at locations on the display such that when the electronic device moves in the XR environment 400, the objects are stationary on the display on the electronic device. Such virtual objects that, in response to motion of the electronic device, retain their location on the display are referred to as head-locked objects or display-locked objects.
In various implementations, the request for content rendering instructions includes a skewing (or other perspective transform) of the content rendering. For example, in various implementations, when the virtual phone 440 is at a first angle to the user (e.g., facing the user), the content rendering has a first horizontal resolution. When the virtual phone 440 is at a second angle to the user (e.g., rotated about a vertical axis of the virtual phone 440 such that the virtual screen 441 is partially turned away from the user), the content rendering has a second (lower) horizontal resolution.
The electronic device sends the request for the content rendering instructions to another electronic device, such as the phone 414, and receives content rendering instructions from the other electronic device. In various implementations, the content rendering instructions include a content rendering (e.g., an image) to be displayed by the electronic device. In various implementations, the content rendering received from the phone 414 is approximately the size and shape of the virtual screen 441 as displayed by the electronic device (e.g., as determined by the pose of the virtual phone 440).
In various implementations, the content rendering instructions include graphic commands interpretable by the electronic device to generate a content rendering. Further, in various implementations, the electronic device generates a content rendering based on the content rendering instructions.
In various implementations, the graphic commands interpretable by the electronic device to generate the content rendering utilize less bandwidth than would the content rendering. In various implementations, the graphic commands include API (application programming interface) commands. For example, in various implementations, the graphic commands include instructions to create a view, add a button at a particular location in the view, add a text field in a particular location in the view, add text to the text field, add an image at a particular location in the view, etc. In various implementations, the electronic device follows the commands to generate (and populate) the view and performs a perspective transform of the view based on the pose of the virtual phone 440 to generate the content rendering.
Thus, in various implementations, the graphic commands include instructions to add an image to a particular location in the view. Further, the graphic commands include data indicative of the image (e.g., an image file). In various implementations, a size and/or resolution of the image transmitted by the phone 414 is based on the pose of the virtual phone 440. In various implementations, the graphic commands exclude elements of the view that would not be visible in the content rendering.
The electronic device displays the content rendering on the virtual screen 441 of the virtual phone 440. In
In various implementations, the electronic device detects the left hand 432 interacting with the virtual screen 441 as a hand gesture event. The hand gesture event indicates a particular hand gesture (e.g., a “tap” performed by extending the pointer finger with the other fingers and thumbs drawn in while the hand moves forward and back) and a particular location in the XR environment 400. The electronic device determines that the location in the XR environment 400 corresponds to a location on the virtual phone 440 and generates a corresponding touch event for the phone 414. The touch event indicates a touch gesture (e.g., a “tap” performed by briefly touching the screen of the phone 414) and a particular location on the phone 414. In various implementations, the data indicative of the user interaction includes the touch event.
During the sixth time period, the XR environment 400 includes the left hand 432 interacting with the virtual screen 441 moving from a particular location within the text field and moving upwards (e.g., so as to scroll the text field).
In various implementations, in response to detecting the left hand 432 interacting with the virtual screen 441 moving from the particular location and moving upwards, the electronic device sends data indicative of the user interaction to the phone 414. In response, the phone 414 generates updated content rendering instructions (based on data received from the application corresponding to the particular application launching affordance) and transmits the updated content rendering instructions to the electronic device.
As an example, in various implementations, the electronic device detects the left hand 432 interacting with the virtual screen 441 as a hand gesture event. The hand gesture event indicates a particular hand gesture (e.g., a “swipe” performed by extending the pointer finger with the other fingers and thumbs drawn in while the hand moves from a first location to a second location) and a particular location in the XR environment 400. The electronic device determines that the location in the XR environment 400 corresponds to a location on the virtual phone 440 and generates a corresponding touch event for the phone 414. The touch event indicates a touch gesture (e.g., a “swipe” performed by moving a contact along a screen of the phone 414) and a particular location on the phone 414.
However, in various implementations, the electronic device generates an updated content rendering without sending data indicative of the user interaction to the phone 414. For example, as the electronic device previously received the text beginning with “First text” and listing eight items, in response to the hand gesture event, the electronic device scrolls the text field without transmitting data indicative of the user interaction to the phone 414.
The electronic device sends the request for the content rendering instructions to the phone 414 and receives content rendering instructions. Further, in various implementations, the electronic device generates a content rendering based on the content rendering instructions and displays the content rendering on the virtual tile 451. In
In various implementations, the request for the content rendering instructions includes an indication of a landscape mode or a portrait mode. Accordingly, in various implementations, the content rendering instructions are generated, by the phone 414, based on a landscape mode or a portrait mode. Thus, in
The method 500 begins, in block 510, with the device determining a pose of a virtual object in a volumetric environment. In various implementations, determining the pose of the virtual object includes determining a position of the virtual object in the volumetric environment (e.g., three-dimensional coordinates of the virtual object in the volumetric environment). In various implementations, determining the pose of the virtual object includes determining an orientation of the virtual object in the volumetric environment.
In various implementations, the virtual object includes a flat two-dimensional surface. For example, in

In various implementations, the request for the content rendering instructions indicates a size of the content rendering. In various implementations, the request for the content rendering indicates a resolution of the content rendering. In various implementations, the request for the content rendering indicates a shape of the content rendering. For example, in various implementations, the request for the content rendering indicates a skewing, an affine transform, or a perspective transform of the content rendering. In various implementations, the request for the content rendering instructions indicates a landscape mode or a portrait mode.
The method 500 continues, in block 530, with the device sending, to a second device, the request for the content rendering instructions. In response to receiving the request for the content rendering, the second device generates the content rendering instructions based on the request for the content rendering instructions.
The method 500 continues, in block 540, with the device receiving, from the second device, the content rendering instructions. In various implementations, the content rendering instructions include graphic commands Thus, in various implementations, the method 500 includes generating a view based on the graphic commands and generating a content rendering based on the view and the pose of the virtual object.
In various implementations, the content rendering instructions include an image. In various implementations, a size and/or resolution of the image is based on the pose of the virtual object. In various implementations, the image is a size and shape of the virtual object. In various implementations, the image includes a matrix of pixels, wherein the matrix of pixels includes a parallelogram-shaped or trapezoid-shaped region of the matrix having RGB values and a transparency value of opaque and the remainder of the pixels have a transparency value indicating that the region is transparent.
In various implementations, the method 500 includes transforming the image based on the pose of the virtual object, e.g., such that the transformed image is the size and shape of the virtual object.
The method 500 continues, in block 550, with the device displaying, based on the content rendering instructions, the content rendering on the virtual object. In various implementations, displaying the content rendering on the virtual object includes generating, based on the content rendering instructions, the content rendering.
In various implementations, displaying the content rendering on the virtual object includes displaying the content rendering on a flat two-dimensional surface of the virtual object. In various implementations, the size and shape of the content rendering is approximately equal to the size and shape of the flat two-dimensional surface displayed by the device. Thus, in various implementations, displaying the content rendering includes hiding the virtual object. For example, in
In various implementations, the method 500 further includes detecting a user input, such as a user input interacting with the virtual object. For example, in
In various implementations, detecting the user input includes detecting a hand gesture event. In various implementations, the method 500 includes mapping the hand gesture event to a touch gesture event. In various implementations, sending the data indicative of the user input includes sending the touch gesture event.
