Translating Combinations of User Gaze Direction and Predetermined Facial Gestures into User Input Instructions for Near-Eye-Display (NED) Devices

A Near-Eye-Display (NED) devices that translates combinations of user gaze direction and predetermined facial gestures into user input instructions. The NED device includes an eye tracking system and a display that renders computer-generated images within a user's field-of-view. The eye tracking system may continually track the user's eye movements with a high degree of accuracy to identify specific computer-generated images that a user is focused on. The eye tracking system may also identify various facial gestures such as, for example, left-eye blinks and/or right-eye blinks that are performed while the specific computer-generated images are being focused on. In this way, NED devices are enabled to identify combinations of user gaze direction and predetermined facial gestures and to translate these identified combinations into user input instructions that correspond to specific computer-generated images.
