Abstract
A near-eye display system includes a display panel to display a near-eye lightfield frame comprising an array of elemental images and an eye tracking component to track a pose of a user's eye. The system further includes a lenslet array and a rendering component to adjust the focal points of the array of elemental images in the integral lightfield frame based on the pose of the user's eye. A method of operation of the near-eye display system includes determining, using an eye tracking component of the near-eye display system, a first pose of a user's eye and determining a desired focal point for an array of elemental images forming an integral lightfield frame based on the first pose of the user's eye. The method further includes changing the focal length of light projecting out of a lenslet array based on the first pose of the user's eye.
