Abstract
An apparatus for tracking eye gaze includes a capacitive sensor array having a plurality of capacitive sensors. The capacitive sensor array is configured to detect eye movement based at least on a proximity of the plurality of capacitive sensors to a part of an eye of a user (e.g., a bulge in the cornea). A frame of the apparatus is configured to be worn on a head of the user and configured to support the capacitive sensor array positioned in front of the eye. A control circuit of the apparatus is configured to receive signals from the capacitive sensor array. A body electrode of the apparatus is positioned on the frame and electrically connected to the control circuit, the body electrode configured to establish an electrical connection with a body of the user. A conductive line of the apparatus connects the body electrode to the control circuit.
