Capacitive gaze tracking for auto-accommodation in a contact lens
Abstract:
A method of capacitive gaze detection for accommodation includes monitoring at least one capacitance value of a capacitive sensor system disposed within a contact lens. The at least one capacitance value varies in response to changes in a gazing direction of a cornea upon which the contact lens is removeably mounted. The changes in the gazing direction of the cornea are detected in real-time based upon changes in the at least one capacitance value. An accommodation actuator disposed within the contact lens is manipulated to automatically change an optical power of the contact lens in response to detecting changes in the gazing direction.
