Abstract
A head mounted display (HMD) includes one or more light field cameras for tracking one or both eyes of a user wearing the HMD. The HMD optionally includes light sources positioned inside the HMD and that illuminate one or both of the eyes of the user. The light field camera captures a plenoptic image of the user's eye. The plenoptic image includes light intensity data and direction data of the captured light rays. An eye tracking system updates a 3D light field model of the user's eye based on depth information from the plenoptic image frame. The eye tracking system identifies an iris plane of the user's eye using the 3D light field model. The eye tracking system determines a gaze direction of the user's eye by identifying the normal to the center of the iris plane.
