Abstract
A head mounted display (HMD) comprises an eye tracking system configured to enable eye-tracking using light. The eye tracking system comprises two or more illumination sources positioned relative to one another and an optical detector in order to capture. The optical detector is configured to capture images of the cornea based on one or more reflections. The eye tracking unit is configured to generate a model of the user's eye. The generated eye model is used to determine eye tracking information such as gaze direction as the user glances at different objects in the HMD.
