mousphere is a concept mouse design for elderly.
The idea of this design is inspired by the traditional Chinese metal exercise ball, which is two round smooth hollow metal ball that you hold in hand and rotate them to exercise the hand muscle. The reason of using the motion to control mouse rather then normal mouse is normal mouse create pain and pressure to the hand. Also some of the elderly have problem on the tension in the muscle of the hand, thus this design allow them to use mouse and help exercise to avoid this disease.
The design use the magnetic force to function the mouse movement, the motion of the rotating give the direction and speed of the control of the pointer on the computer screen. And the button provide the normal left and right click on a mouse, which this concept design can function as a normal mouse.
