Abstract: Head-mounted virtual and augmented reality display systems include a light projector with one or more emissive micro-displays having a first resolution and a pixel pitch. The projector outputs light forming frames of virtual content having at least a portion associated with a second resolution greater than the first resolution. The projector outputs light forming a first subframe of the rendered frame at the first resolution, and parts of the projector are shifted using actuators, such that physical positions of light output for individual pixels occupy gaps between the old locations of light output for individual pixels. The projector then outputs light forming a second subframe of the rendered frame. The first and second subframes are outputted within the flicker fusion threshold. Advantageously, an emissive micro-display (e.g., micro-LED display) having a low resolution can form a frame having a higher resolution by using the same light emitters to function as multiple pixels of that frame.

Abstract: A VR system is described. A simulation engine receives position data of an object during a scenario and transmits the position data to a modular symptoms generator. The modular symptoms generator queries a database to determine predefined position data for the object during the scenario and compares the captured position data with the predefined position data for the object during the scenario. If the position data for the object meets or exceeds the predefined position data, the modular symptoms generator executes a first modification on a portion of the scenario and if the position data for the object fails to meet or exceed the predefined position data, the modular symptoms generator executes a second modification on a portion of the scenario. The first modification results in a more favorable situation as compared to the situation resulting from the second modification.
