A server device and method are provided for use in predictive server-side rendering of scenes based on client-side user input. The server device may include a processor and a storage device holding instructions for an application program executable by the processor to receive, at the application program, a current navigation input in a stream of navigation inputs from a client device over a network, calculate a predicted future navigation input based on the current navigation input and a current application state of the application program, render a future scene based on the predicted future navigation input to a rendering surface, and send the rendering surface to the client device over the network.

Predictive server-side rendering of scenes

A head mounted display device including a processor configured to compute a rendered rendering surface of a predicted scene having a predicted user viewpoint, the predicted user viewpoint being a prediction of a viewpoint that a user will have at a point in time that was predicted for the user of the head mounted display device prior to the point in time, receive, from the user input device, a subsequent user navigation input near the point in time in the stream of user input, determine an actual user viewpoint based on the subsequent user navigation input, determine a user viewpoint misprediction based on the predicted user viewpoint and the actual user viewpoint, and reconstruct a viewport for the actual user viewpoint from the rendered rendering surface.

Reconstructing viewport upon user viewpoint misprediction

A client device and method are provided for reconstructing a viewport from a rendered rendering surface of a predicted user viewpoint in order to reduce user perceived latency of the network. The client device may execute instructions to: receive, from a server device over a network, a rendered rendering surface of a predicted scene having a predicted user viewpoint, receive, from the user input device, a subsequent user navigation input in the stream of user input, determine an actual user viewpoint based on the subsequent user navigation input, determine a user viewpoint misprediction based on the predicted user viewpoint and the actual user viewpoint, and reconstruct a viewport for the actual user viewpoint from the rendered rendering surface.

A client device and method are provided for use in synthesizing a second eye viewport using interleaving in order to reduce bandwidth costs. The client device may comprise a user input device that receives a stream of user input, a stereoscopic display device, a processor, and a storage device holding instructions for a client application program, executable by the processor to obtain, at a view interpolation module of the client application program, a current rendered rendering surface representing a current view of a scene for a first eye of a user and a previously rendered rendering surface representing a past view of the scene for a second eye of the user, synthesize and display a current second eye viewport representing a current view of the scene for the second eye of the user based on the current rendered rendering surface and the previously rendered rendering surface.
