Best mouse for a person with trembling hands
I didn't want to let him use the integrated track pad because I found it very unpractical, so I ordered an Apple (wired) mouse for him. Unfortunately his hand is often trembling, and he has very little space to move the mouse, so we need to lift the mouse to move it without affecting the pointer's position an be able to move the pointer from the top-left corner to the bottom-right corner of the screen.
All this causes him great difficulty (pointing precisely and lifting the mouse) so I wondered if a mouse with a track ball would be more suitable.
What do you think ?
