Abstract
Apparatus, systems and methods that facilitate eye tracking using a contact lens are provided. In some aspects, the contact lens includes: a substrate; an antenna, disposed on or within the substrate, that harvests radio frequency energy; an integrated circuit, disposed on or within the substrate, that receives power from the antenna; and electrical components, disposed on or within the substrate, that determine motion of an eye over which the contact lens is placed, and perform tracking of the eye based, at least, on the motion. For example, the motion of the eye can be determined based on telemetry components fabricated on or within a substrate of the contact lens. In some aspects, the contact lens can include light emitters that radiate light in a direction of the gaze of the wearer of the contact lens. A heads-up device can perform eye tracking based on the direction of the light beams.
