Startup Idea : Shifting computer mouse for carpal tunnel

The problem is repetitive injury/carpal tunnel that happen with overuse of hand and arm, overtaxing the tendons and nerves. The result is pain, numbness, tingling, etc. in the hand and arm which could lead to surgery to alleviate the symptoms. One way I have been addressing is through my computer mouse. There are many different kinds and I have tried several. But, these devices can continue the repetitive motion. I would like to see a computer mouse that utilizes several different technologies and automatically shifts the user through them during the day to keep different tendons and nerves in play.
