Abstract

See full text

A system includes a pair of electronic contact lenses that obtain respective motion sensor measurements in response to eye movements. A tracking module derives estimated orientations for both eyes based on the sensor measurements and a set of correlations and constraints that describe human eye movement. The model describes the limited number of ways that an individual eye can move and relationships between relative movement of the left and right eye. The tracking module performs filtering based on the measurements and the eye model to suppress noise and generate orientation estimates for both eyes.
