The smart contact lenses for human-machine interaction (HMI) track eye movements and can be used for health care and augmented reality (AR) applications. They work on radio frequencies. The chip-free and battery-free lenses employ the frequency encoding strategy and successfully detect eye movement and closure. The high angular accuracy of the lenses enables eye command recognition, which can be helpful for robot control.
