Nvidia Develops Lightweight VR Gaze Tracking System Using LED Sensors
uploadvr | March 27, 2020
Nvidia’s new gaze tracker uses a capability of common LEDs — their ability to both emit and sense light — to simplify the process of determining the eye’s position relative to a display. Like other gaze tracking systems, the Nvidia system uses a ring of infrared LEDs to project unseen light into the eye, but here, LEDs also are used for color-selective sensing from the same location. This enables the smallest and lowest-cost gaze tracking yet developed, the researchers note, while matching the accuracy and sampling rates of today’s most common solutions.
