MINIMAL LATENCY APPARATUS AND METHOD FOR SUPPORTING FOVEATED RENDERING
A virtual reality/augmented reality (VR/AR) wearable assembly is described herein. The VR/AR wearable assembly includes a display device, a photosensor oculography (PSOG) assembly including an eye tracking assembly, and a processor coupled to the PSOG assembly and the display device. The processor including an eye-tracking module configured to execute an algorithm to render computer-generated images on the display device including the steps of detecting a saccade of a corresponding eye of the patient via the eye tracking assembly and determining an initial saccade gaze position location of the corresponding eye associated with the detected saccade, determining a peak velocity of the saccade, determining a final saccade end gaze position based on the determined peak velocity of the saccade, and rendering a foveated image on the display device at an image location corresponding to the determined final saccade end gaze position.
1 . A virtual reality/augmented reality (VR/AR) wearable assembly comprising:
a wearable frame adapted to be worn over a patient's eyes;
a display device mounted to the wearable frame;
a photosensor oculography (PSOG) assembly mounted to the wearable frame and including an eye tracking assembly; and
a processor coupled to the PSOG assembly and the display device, the processor including an eye-tracking module configured to execute an algorithm to render computer-generated images on the display device including the steps of:
detecting a saccade of a corresponding eye of the patient via the eye tracking assembly and determining an initial saccade gaze position location of the corresponding eye associated with the detected saccade;
determining a peak velocity of the saccade;
determining a final saccade end gaze position based on the determined peak velocity of the saccade; and
rendering a foveated image on the display device at an image location corresponding to the determined final saccade end gaze position.
