Abstract

An eye-tracked head-mounted display (ET-HMD) system is able to display virtual images as a classical headmounted display (HMD) does, while additionally tracking the gaze direction of the user. An HMD with fullyintegrated eyetracking capability offers multi-fold benefits, not only to fundamental scientific research but also to emerging applications of such technology. A key limitation of the state-of-the-art ET-HMD technology is the lack of compactness and portability. In this paper, we present an innovative design of a high resolution optical see-through ET-HMD system based on freeform optical technology. A prototype system is demonstrated, which offers a goggle-like compact form factor, non-obstructive see-through field of view, true high-definition image resolution for the virtual display, and better than 0.5 arc minute of angular resolution for the see-through view. We will demonstrate the application of the technology as an assistive and augmentative communication (AAC) device.
