Tongue Drive System (TDS) is a tongue operated, unobtrusive, minimally invasive, wireless assistive technology (AT), which can enable people with severe disabilities to control different devices using their tongue motion. TDS can translate specific tongue movements into user-defined commands by detecting the position of a small permanent magnetic tracer attached to the users' tongue. We have built an external TDS (eTDS) prototype on a wireless headphone and interfaced it to a laptop and a commercial powered wheelchair (PWC). eTDS performance was evaluated by eight subjects with high level (C3 approximately C5) spinal cord injury (SCI) at the Shepherd Center in Atlanta, GA. Preliminary results show that all the subjects can successfully perform common tasks related to computer access, such as controlling a mouse cursor or playing a computer game, as well as complex wheelchair navigation tasks, such as driving through an obstacle course.
舌驱动系统（TDS）是一种由舌头操作、不引人注意、微创的无线辅助技术（AT），它能使严重残疾人士通过舌头运动控制不同设备。TDS通过检测附着在使用者舌头上的一个小型永磁追踪器的位置，将特定的舌头动作转化为用户定义的指令。我们在一副无线耳机上构建了一个外部舌驱动系统（eTDS）原型，并将其与一台笔记本电脑和一辆商用动力轮椅（PWC）连接。位于佐治亚州亚特兰大市谢泼德中心的8名高位（C3至C5）脊髓损伤（SCI）患者对eTDS的性能进行了评估。初步结果表明，所有受试者都能成功完成与计算机操作相关的常见任务，如控制鼠标光标或玩电脑游戏，以及复杂的轮椅导航任务，如穿越障碍赛道。
