[Blindmath] touchpads for drawing and feedback...

[David Engebretson Jr.]

I've been trying to find a touchpad, in lew of a mouse, that would work with 
the program dr. baldwin has been creating  to evaluate shapes with sound 
feedback.

Does anyone have any recommendations for a touchpad that is at least 8.5x11, 
scale-able with screen resolution, and is plug and play with usb on a 
windows xp machine.

suggestions?

best,
david
