The Goldtouch Mouse from KeyOvation is based on the shape of the original Goldtouch Mouse, leveraging the slope angles specified by ergonomists and health safety professionals. The ergonomic design supports the hand in a naturally sloping angle that places the wrist in a neutral position. The mouse wheel is placed forward on the mouse to minimize bending of the interphalangeal joints and provide more comfortable scrolling. There is no need to adapt to a radically mouse orientation to gain ergonomic benefits. The mouse positions the hand and wrist in a naturally sloping angle. The user is immediately oriented to the shape and angle of the mouse, and is therefore, immediately productive.
