Over the years there hasn’t been a mouse designed specifically for the elderly. Hard to grip the mouse and it keeps sliding and slipping when the buttons are pushed. Sometimes it is hard for the elderly to recognize the front or back of the mouse.
In response to these problems we made quick foam mock-ups and some volume mockups to test for ergonomics and best hand positions. The first form is more bullbus at the back and tapors into a beak like shape to reduce sliding and slipping. It also points in the direction of the computer to indicate front and back of the mouse. Another form is more truncated to help squeeze buttons more effectively and easier to hold and navigate. The third form is combination of the first two ideas. Flat area at the front to minimize slipping and more rounded at the back for better gripping.
