I adapted my own mouse to alleviate the hand tremors.Simply making any mouse heavier will work for most. As soon as I grasp the hefty mouse the tremors stop. I have sought technical assistance in developing my invention from those one would think would be most interested with no success. ie Parkinsons Foundation, Dept. of Health, etc.
I can see the mouse settings being useful to let the computer know what constitutes a deliberate mouse movement, but indeed a heavier mouse would seem to help the user know when the mouse pointer is going to move.
Think there might be issues with RSI or similar with using a heavier mouse though.
