FOR people with hand tremors, using a computer mouse can be arduous, or downright impossible. IBM believes it has a solution that will allow millions of people with this problem to use a computer normally.
Jim Levine, a researcher at IBM’s T. J. Watson Research Center in New York, has invented a mouse adapter that filters out the “noise” produced by shaky hand movements. Compatible with any computer, the adapter has a small microprocessor that digitally smoothes the motion data from the mouse. In effect, it suppresses rapid tremor oscillations, while leaving the slow, steady progress toward the user’s goal.…
