The body of a mouse pointing device is modified to accommodate large hands by extending the side of the mouse on the thumb side to match the size of the hand. Symmetrical mouse designs place the mouse buttons under the middle and index fingers, with the ring finger and pinky and thumb holding the mouse. A small mouse body forces the user to hold the mouse with the thumb in an unnatural position, thereby resulting in muscle strain and fatigue. By extending the mouse body where the thumb meets the body, the effort in using the mouse is reduced.
