Abstract

Current invention propounds a novel active contact lens device, system, as well as, a corresponding method of operation of such contact lens with an embedded orientation determination mechanism. The system, furthermore, utilizes an onboard, integrated orientation and gaze sensing component to determine eye orientation, in 3D (x,y,z) dimension corresponding to the direction of eye gaze, or in 2D (x,y) dimension, denoting orientation relative to the horizontal or vertical line of the eye, also known as, the horizontal or vertical meridian of the eye. Such a system may be used to provide rich augmented reality (AR) or virtual reality (VR) experience to its user/wearer. Hereby, we propose to incorporate several electronic, electro-optical, optical or other types of components into the contact lens substrate and interconnect them to form such an innovative AR/VR enabled active contact lens system. The system proffered herein, may incorporate and integrate a number of the following components: an integrated orientation sensing module, a positioning module (a location determination module—for example GPS sensor), an integrated substantially transparent, or semi-transparent, or non-transparent display device, a source of electric power, a communication component, a processing component, and an audio output device. Some constituent modules may be integrated into the lens substrate and some may be located remotely and accessible via wireless communication channel. The smart contact lens with an embedded orientation module may be used to implement a variety of reactive, adaptive, predictive, behavior monitoring and analyzing systems.
