Abstract

Operation of an electronic contact lens takes into account saccadic motion of the eye and reduced visual perception during saccades (saccadic suppression). The user's eye motion is tracked, and onset of a saccade is detected based on the eye's motion. For example, saccades may be detected when the eye's acceleration or jerk exceeds a threshold. The endpoint of the saccade is then predicted in real-time while the saccade is still occurring. This may be the temporal endpoint (i.e., when the saccade ends) and/or the positional endpoint (i.e., the eye position at the end of the saccade). Operation of the electronic contact lens is adjusted based on the predicted endpoint.
