A wireless computer mouse for use by someone right handed. The mouse has an ergonomic vertical set up so that the control buttons and scrolling wheel are on the right side rather than the top of the device. In the use of this mouse the hand is held in a vertical handshake position which encourages a neutral posture and generally avoids forearm twisting. The designer, Jack Lo, invented the vertical mouse in 1994 due to the discomfort he had when using a conventional mouse. His invention was the first mouse to support a hand in a fully upright handshake position for eliminating the arm twisting required by ordinary mice. The first Evoluent VerticalMouse became commercially available in late 2002.
