ABSTRACT:
A computer pointing-input device has a low risk of inducing Repetitive Stress Syndrome and Carpal Tunnel Syndrome in a user by providing thumb and hand actuated controls. A main body (16) of the device is held laterally in a hand of the user with the thumb of the hand resting on a thumb switch (21). The palm of the hand rests on the main body (16) and an outer edge of the palm of the hand rests on a hand switch (31). The thumb switch (21) is operable by a downward pressure from the user's thumb, and the hand switch (31) is operable by downward pressure from the outer side of the user's palm.
