Smyle Mouse provides hands-free computer mouse control via gentle head motions and smiles. This can be very useful for people with disabilities or impairments related to use of hands, arms or fingers. This can include severe disabling conditions such as ALS, Spinal Cord Injury, Multiple Sclerosis, Stroke, Cerebral Palsy, Neuro-muscular diseases, and others, but also pain/discomfort in hands/arms due to Carpal Tunnel Syndrome and Arthritis. People looking for ergonomic computer mice can also use Smyle Mouse. What can be easier on your hands than not using them at all?!
