Abstract
A method for operating a display of a virtual reality or augmented reality headset includes determining a direction of movement of a user's eye, estimating a future gaze direction from the determined direction of movement, and rendering an image on the display having higher resolution image data in a region including the estimated gaze direction and lower resolution image data outside of the region including the determined gaze direction. The determining the direction of movement of the user's eye includes illuminating the user's eye with a beam of light emitted by a first laser, receiving, at the first laser, light redirected from the user's eye_such that self-mixing interference occurs within the laser cavity between light generated by the first laser and the light redirected from the user's eye, measuring the self-mixing interference, and determining a direction of movement of the user's eye-from the measured self-mixing interference.
