title: Wireless control of smartphones with tongue motion using tongue drive assistive technology.
abstract: Tongue Drive System (TDS) is a noninvasive, wireless and wearable assistive technology that helps people with severe disabilities control their environments using their tongue motion. TDS translates specific tongue gestures to commands by detecting a small permanent magnetic tracer on the users' tongue. We have linked the TDS to a smartphone (iPhone/iPod Touch) with a customized wireless module, added to the iPhone. We also migrated and ran the TDS sensor signal processing algorithm and graphical user interface on the iPhone in real time. The TDS-iPhone interface was evaluated by four able- bodied subjects for dialing 10-digit phone numbers using the standard telephone keypad and three methods of prompting the numbers: visual, auditory, and cognitive. Preliminary results showed that the interface worked quite reliably at a rate of 15.4 digits per minute, on average, with negligible errors.
