With the Hippus Handshoe mouse support is provided for fingers and thumb. The finger support is a curved surface which follows the finger arch of the relaxed finger (Extensor and Flexor muscles in equilibrium). In view of the anatomical shape of the human hand the thumb supporting element lies at a pre-defined lower level relative to the finger supporting part. Both supports, for thumb and fingers, join to provide the hand palm support. The hand palm and finger support starts at the wrist and ends at the finger tips and thus follows the full length of the inner contour of the hand. The width of the hand palm and finger support is defined from its highest point up to the base of the mouse. The outer edge of the little finger (Ulnar) side of the mouse is also provided with a supporting contour.
