Rotation direction control by finger movement

Control of direction of motor rotation is achieved via real-time image acquisition and processing. The model is prepared using Matlab and Simulink platforms and input is taken via any camera attached to the system. Commands are executed to rotate the rotor in either direction depending upon the movement of any object in front of the camera, be it a pencil, a pen, a human finger, a human eyeball or any body part for that matter. No costly system is required besides a webcam for image capturing and a dc motor. This novel controlling system befits all and highly reduces human effort. Besides bringing rapidity in execution of systems, it is a boon for the motor disabled.
