Abstract

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.

ASYMMETRICAL MOUSE (Cont'd)

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.

The shape of the modified mouse body resembles an L. The vertical section of the L represents the body of the mouse, and the horizontal section of the L is the proposed new extension for the thumb. By adjusting the size and position of the extension, hands of various sizes can be accommodated. Figure 1 illustrates an example of the shape of the asymmetric mouse of a right handed person. It is noted that the extension can be extended to the other side of the mouse for a left handed person. In other words, the extension of the asymmetrical mouse can be a sliding bar which can slide to either side of the mouse.
