Abstract
A method for color-based calibration for eye-tracking includes presenting a calibration image to an eyebox area via a waveguide of a head mounted display (HMD). An estimated pupil center location of an eye is determined with an eye-tracking system. Next, user input is received in response to the calibration image. The user input includes an indication of a perceived color nonuniformity of the calibration image. The estimated pupil center location is then adjusted based on the user input.
