Eye tracking system for vr/ar hmd units including pancake lens modules

Abstract

A virtual reality (VR) wearable assembly is described herein. The VR wearable assembly includes a wearable frame adapted to be worn over a patient's eyes and a pair of photosensor oculography (PSOG) assemblies mounted to the wearable frame such that each PSOG assembly is positioned adjacent a corresponding eye of the patient. Each PSOG assembly includes a display housing having an inner surface defining an interior cavity extending between a first end and second end, a micro-OLED display coupled to the display housing and positioned within the interior cavity adjacent the second end of the display housing, an eye tracking assembly coupled to the display housing and positioned adjacent the first end of the display housing, and a pancake lens mounted to the display housing and positioned within the interior cavity between the eye tracking assembly and the micro-OLED display.
