Abstract
Eye safety and eye tracking accuracy is enhanced through pupil-aware eye tracking, where a fringe pattern projection or illumination onto the eye is locally dimmed in an area corresponding to the pupil. Fringe projection local dimming is accomplished by modifying (locally dimming) the fringe pattern at the projector. Illumination local dimming is accomplished at the light source (e.g., a laser source) before the light is provided by a micro-electromechanical system (MEMS) to the eye. An amount of light provided to non-pupil areas such as sclera may be increased to enhance a signal-to-noise ratio (SNR), which may lead to more accurate eye tracking.
