A device for generating and delivering control signals to a computer has a housing with a top foot engaging surface on a top portion. Roller bearings captivated between the top portion and a base portion are disposed in moving engagement with a plate, thereby allowing the user's foot to move the top portion relative to the base. Optical sensors detect movement of the top portion and transmit electrical signals to a microcontroller which interprets the linear directional movement relative to X and Y coordinates. The user's foot is selectively moved over either a left or right light sensor to perform left and right mouse click operations. An external RCA jack allows for attachment of external cursor control devices, such as hand or finger operated mouse click controls. In one embodiment, magnetic switches are provided in a keyboard to perform left and right click operations, wherein a magnetic ring worn on the hand of the user is selectively passed over either a left or right magnetic switch to perform the left or right click operation. In an alternative embodiment, magnetic switch devices are worn on a finger of the left and right hands and magnetic rings worn on the thumbs are used to selectively perform the left and right click operations by moving the magnetic ring on either the left or right hand in close proximity to the magnetic switch worn on the same hand.
