            Written in C

            Low response time (specify)
            Test cases: poke specific coordinates several times, make sure we get the same data (within margin TBD)
            Use a target area (TBD)

            Rabbit or ARM microcontroller
            Accept TBD% average-sized fingers
            Accept TBD% average-sized hand edges
            Reject TBD% average-sized palms
            (Test the above with many users with a range of hand sizes)
