Abstract
The present invention is an improved system for use of eye tracking including spatial mapping percepts in a visual prosthesis by presenting an electrically induced precept through a visual prosthesis, requesting a subject look to the direction of the percept and tracking their eye movement. Eye movement is both faster and more accurate than asking a visual prosthesis user to point to the location of a percept. This method can be beneficial in a retinal prosthesis, but is particularly useful in a cortical visual prosthesis where visual cortex does not match the retinotopic map. Methods are presented for calibrating an eye tracker. Eye tracking hardware may also be used for blanking video information base on the subject's natural blink reflex.
