Finally make the USB Trackball controller I always needed. Inspired by Caleb's thecontrollerproject.com. A defective left hand prevents me from moving from mouse to keyboard quickly, or typing efficiently. If you ever held game controllers upside down, or crossed over left and right, you know some of the problems I have. The only mouse that works for me with minimal pain or frustration is the Logitech Trackball Marble Mouse.
1. Make several designs around accessibility issues.
2. Make some mistakes and learn from them.
3. Make the ultimate pointing device designed for my hand.
4. Long term goal is to build up a work area, experience and determination to contribute to thecontrollerproject.com.
I am going to start hacking the Logitech Trackball Marble Mouse, and build around that first, then hopefully move up to more effective designs.
