摘要:
An eye-mountable device includes an enclosure material, a capacitive sensor system, and a controller. The enclosure material has a concave surface and a convex surface. The concave surface is configured to be removeably mounted over a cornea and the convex surface is configured to be compatible with eyelid motion when the concave surface is so mounted. The capacitive sensor system is disposed within the enclosure material. The capacitive sensor system has at least one capacitance value that varies with changes in a gazing direction of the cornea. The controller is disposed within the enclosure material and electrically connected to the capacitive sensor system. The controller is configured to measure the capacitance value of the capacitive sensor system to detect the changes in the gazing direction.
