Developing Gaze Tracker for Diffractive-Optics-Enabled Near-to-Eye Displays

摘要

A near-to-eye display (NED) is one display solution where an image can be perceived to be larger than the actual physical device on which it is displayed. A thin, light user friendly and high-performing see-through NED has been prototyped using very thin plastic light guides with diffractive structures on the surfaces. To be able to efficiently interact with the displayed user interface, we have also integrated a video-based gaze tracker into the NED, using similar diffractive optics.
