Ergonomics The Right Handed Evoluent VerticalMouse The Evoluent VerticalMouse 3 is a patented mouse that supports your hand in a relaxed handshake # position, eliminating the arm-twisting required by ordinary mice. The VerticalMouse remains steady, not moving sideways when clicking with normal force as the thumb naturally opposes the finger movements. The mouse has a patented shape that supports your hand in a fully upright handshake position that eliminates the forearm twisting required by ordinary mice, thus relieving hand, wrist, and arm pain.
