Abstract: A method for determining a focal point depth of a user of a three dimensional (“3D”) display device includes tracking a first gaze path of the user. The method also includes analyzing 3D data to identify one or more virtual objects along the first gaze path of the user. The method further includes when only one virtual object intersects the first gaze path of the user identifying a depth of the only one virtual object as the focal point depth of the user.

Abstract: Methods and systems are provided for a reprojection engine for augmented-reality devices. The augmented-reality device projects virtual content within a real-world environment. The augmented-reality device tracks a six degrees of freedom headpose of the augmented-reality device, depth information of the virtual content, motion vectors that correspond to movement of the virtual content, and a color buffer for a reprojection engine. The reprojection engine generates a reprojection of the virtual content defined by an extrapolation of a first frame using the headpose, the depth information, motion vectors, and the color surface data structure. The reprojected virtual content continues to appear as if positioned with the real-world environment regardless of changes in the headpose of the augmented-reality device or motion of the virtual content.

Abstract: A computer implemented method for warping virtual content includes generating warped virtual content by transforming source virtual content. The method also includes determining whether a memory location corresponding to an X, Y location of the warped virtual content in an output frame of reference is occupied by pre-existing virtual content. The method further includes storing the warped virtual content in the memory location if the memory location is not occupied. Moreover, the method includes comparing respective Z locations of the warped virtual content and the pre-existing virtual content to identify virtual content with a Z location closer to a viewing location if the memory location is occupied. The method also includes storing the warped virtual content in the memory location corresponding to the X, Y location if a Z location of warped virtual content is closer to the viewing location than a pre-existing Z location of pre-existing virtual content.

The method also includes a second source generating second virtual content based on a second pose. The method further includes a compositor processing the first and second virtual content in a single pass. Processing the first and second virtual content includes generating warped first virtual content by warping the first virtual content based on a third pose, generating warped second virtual content by warping the second virtual content based on the third pose, and generating output content by compositing the warped first and second virtual content.

Abstract: An augmented reality viewing system is described. A local coordinate frame of local content is transformed to a world coordinate frame. A further transformation is made to a head coordinate frame and a further transformation is made to a camera coordinate frame that includes all pupil positions of an eye. One or more users may interact in separate sessions with a viewing system. If a canonical map is available, the earlier map is downloaded onto a viewing device of a user. The viewing device then generates another map and localizes the subsequent map to the canonical map.

Abstract: A method of assessing latency in a communications network comprising attempting to contact from a UE in a cellular network a specific internet resource with a HTTP request addressed to the resource, and capturing data specifying the period between making the attempt and receiving at the UE from the resource a response to the request. Thus data can be obtained from which can be made an end-to-end measurement of the latency affecting a user of a UE. Such measurements can be used by the operator of the communications network to, amongst other things, assess whether the network is performing satisfactorily, to advise users about the performance of the network and to determine that hardware or software within the network needs repair, upgrade or augmentation.

Abstract: Techniques for calculating a predicted head pose time for a display device are described herein. A request to start a frame is generated. A target finish time stamp associated with rendering the frame is calculated. A number of VSync periods from a last VSync to a target VSync is determined based on the target finish time stamp. A target VSync time stamp is calculated based on the number of VSync periods from the from the last VSync to the target VSync. The target VSync time stamp is compared to the target finish time stamp. The predicted head pose time is calculated based on the target VSync time stamp and a fixed platform offset.

Abstract: Disclosed is an improved approach for generated recordings from augmented reality systems from the perspective of a camera within the system. Instead of re-using rendered virtual content from the perspective of the user's eyes for AR recordings, additional virtual content is rendered from an additional perspective specifically for the AR recording. That additional virtual content is combined with image frames generated by a camera to form the AR recording.
