For some people, touching a touch screen is difficult, if not
impossible. According to Georgia Tech, more than 200,000 kids in
the U.S. public school system have some sort of orthopedic
disability that hinders them from experiencing the vast
information that awaits them on a tablet or smartphone. Children
with neurological disorders -- such as muscular dystrophy,
cerebral palsy, and spina bifida -- can also have difficulty
using touch-screen devices due to motor skill impairments. The
need to counteract this limitation inspired Ayanna Howard, a
Georgia Tech engineering professor, and graduate student Hae Won
Park to create Access4Kids, a prototype assistive device that
could level the playing field. The wireless-enabled Access4Kids
can be worn on the forearm, or attached to a wheelchair. To make
it work, the child merely touches one of three pressure-
measuring sensors, which convert taps and swipes into highly
accurate gestures that makes tablet operation easier for those
lacking fine-motor skills. In a press
