Touch Feedback for Rehabilitation

Profs at IITB are planning to make a foot-operated touch screen for the disabled and I was wondering wheter we could give it some Haptic Feedback.

Say you have a Touch Screen – a planar rectangular screen partitioned as 9 (3×3 grid of) virtual buttons. No partitions exist physically. Can we send a tactile feedback to the user by vibrating one of these cells? Say by using 4 vibrators at the corners of the screen and varying their intensity? Contrast this with having 9 vibrators on each of the cells (not a very smart idea).

Can you think of any techniques of sending localized vibrations (haptic feedback)? Let me know.
