2023年8月23日 · The EOG acquisition system is interfaced with an ATmega AVR microcontroller to acquire a dataset that can be used for controlling hardware such as Light Emitting Diodes (LEDs), wheelchair, and robot arm.

An Electro-Oculogram (EOG) is a device which measures the position of the retina along with whether the eye is open or closed using electrodes. These electrodes can be placed in pairs above and below or to the sides of the eye. Since the eye acts as a dipole, as one looks around, the potential di erence
