Abstract
A light-emitting contact lens and a method and system for tracking a user's eye position using the light-emitting contact lens are disclosed. The eye position tracking can be used, for example, to allow the user to interact with a display device such that the position of the user's eye determines the image generated by the display device. Thus, as the user's eye moves, the image on the display device will be altered to represent the new position (e.g., viewing angle) of the user with regard to the display device.
