舌头驱动系统（TDS）是一种非侵入性、微创、可穿戴和无线的舌头-计算机接口（TCI），其可以通过检测附接到用户舌头上的小型永磁示踪器的位置来推断其用户的意图，所述意图以其自愿的舌头运动来表示。任何特定的舌头运动都可以被转换成用户定义的命令，并用于访问和控制用户环境中的各种设备。最新的外部TDS（eTDS）原型是建立在无线耳机和接口到笔记本电脑和电动轮椅。使用定制的传感器信号处理算法和图形用户界面，在佐治亚州亚特兰大市的Shepherd中心，由13名患有高位脊髓损伤（C2-C5）的幼稚受试者评价了eTDS的性能。人体试验的结果表明，计算机访问的平均信息传输速率为95位/分钟，准确率为82%。这种信息传输速率比在人类受试者身上测试的基于EEG的BCI高出约两倍。研究还表明，受试者对电动轮椅有直接和完全的控制，以至于他们能够执行复杂的轮椅导航任务，例如驾驶通过障碍物。
The tongue drive system (TDS) is an unobtrusive, minimally invasive, wearable and wireless tongue–computer interface (TCI), which can infer its users' intentions, represented in their volitional tongue movements, by detecting the position of a small permanent magnetic tracer attached to the users' tongues. Any specific tongue movements can be translated into user-defined commands and used to access and control various devices in the users' environments. The latest external TDS (eTDS) prototype is built on a wireless headphone and interfaced to a laptop PC and a powered wheelchair. Using customized sensor signal processing algorithms and graphical user interface, the eTDS performance was evaluated by 13 naive subjects with high-level spinal cord injuries (C2–C5) at the Shepherd Center in Atlanta, GA. Results of the human trial show that an average information transfer rate of 95 bits/min was achieved for computer access with 82% accuracy. This information transfer rate is about two times higher than the EEG-based BCIs that are tested on human subjects. It was also demonstrated that the subjects had immediate and full control over the powered wheelchair to the extent that they were able to perform complex wheelchair navigation tasks, such as driving through an obstacle course.
