Abstract :
A new and innovative method to measure the eye movement in a wireless manner was proposed. We verified the feasibility of our idea by fabrication and performance test of a prototype system. The prototype system consisted of a contact lens with a ring-shaped thin magnet, and eyeglasses frame-shaped PCB with analog/digital signal processing circuitry as well as four magnetoresistive sensors. This new method based on the magnetic contact lens sensing technique (MCLST) is expected to overcome all the disadvantages of the existing techniques.
