Design of eye-machine interaction system (IMAGE)
Caption
(a) Left: encoding of blink information, the schematic indicates that the brain generates specific commands and stimulates the eyes to blink accordingly when a specific situation is encountered. Centre: EMI lens. Right: decoding the blink information for machine interface, healthcare, and AR/VR. (b) I, The exploded structure diagram of the blink-recognizable EMI lens, II, digital photographs of the EMI lens in different orientations. (c) The internal circuit of the EMI lens and the reading circuit of the frequency signal. (d) The encoding and decoding process of blink information. The capacitance of the sensor in designed EMI lens changes when the eyes switch between different states (eyes open, squinting, and eyes closed), and then covert to frequency, which is recorded by the external coil and transmitted to the electrical circles for signal process, finally decoding for the drone control application.
