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.
舌驱动系统（TDS）是一种无创、无线且可穿戴的辅助技术，它能帮助严重残疾人士通过舌头运动来控制周围环境。TDS通过检测用户舌头上的一个小型永久磁性追踪器，将特定的舌头动作转化为指令。我们已通过一个定制的无线模块将TDS与智能手机（iPhone/iPod Touch）相连，并将该模块添加到iPhone上。我们还在iPhone上实时移植并运行了TDS传感器信号处理算法和图形用户界面。四名身体健全的受试者对TDS-iPhone界面进行了评估，他们使用标准电话键盘拨打10位电话号码，并采用了三种提示数字的方法：视觉、听觉和认知提示。初步结果表明，该界面工作相当可靠，平均每分钟可拨打15.4个数字，错误率可忽略不计。
