Vibrating Watch Helps People with Parkinson’s Disease Write

A watch developed by Haiyan Zhang, a Microsoft researcher, makes writing easier for people with Parkinson’s disease. It was created to help Emma Lawton, a graphic designer diagnosed with early-onset Parkinson’s at age 29, to write again. Packed with vibrating motors, a wearable prototype of the watch rhythmically pulses on the wrist. The specific therapeutic mechanism of the watch is still unknown, but it is believed to work by overcoming an erroneous feedback mechanism that underlies parkinsonian tremor.
