Abstract: A gaze tracking system for use by the driver of a vehicle includes an opaque frame circumferentially enclosing a transparent field of view of the driver, light emitting diodes coupled to the opaque frame for emitting infrared light onto various regions of the driver's eye gazing through the transparent field of view, and diodes for sensing intensity of infrared light reflected off of various regions of the driver's eye.

Abstract: Methods are disclosed herein to blur an image to be displayed on a stereo display (such as virtual or augmented reality displays) based on the focus and convergence of the user. The methods approximate the complex effect of chromatic aberration on focus, utilizing three (R/G/B) simple Gaussian blurs. For transparency the methods utilize buffers for levels of blur rather than depth. The methods enable real-time chromatic-based blurring effects for VR/AR displays.
