While the augmentation of head-mounted displays (HMDs) with eye-tracking (ET) capabilities adds challenges to designing compact and portable displays, a systematic approach to integration offers opportunities to improve overall performance and robustness. To investigate the design and optimization of illumination schemes in an ET-HMD system, we present a simulated eye illumination and imaging system, which allows us to explore the critical parameters that affect the quality of the eye illumination. We present details on the modeling process and simulation results.

We present a novel foveated imaging system which consists of three major components: a foveated imager, a peripheral imager, and a 2D scanning sub-system. The foveated imager captures a narrow field of view (FOV) with high angular resolution to mimic the foveated region of interest (FRoI), and the peripheral imager captures a wide FOV with low angular resolution to provide the peripheral region for context. The scanning system, implemented with a single-element two-axis MEMS mirror, is capable of sweeping the FRoI across the entire FOV at a maximum speed of 100Hz. A bench prototype and experimental results are presented as verifications of our optical design concept and feasibility.
