Typing performance of a full alphabet keyboard and a joystick type of mouse (with on-screen keyboard) provided by a wireless integrated tongue control system (TCS) has been investigated. The speed and accuracy have been measured in a form of a throughput defining the true correct words per minute [cwpm]. Training character sequences were typed in a dedicated interface that provided visual feedback of activated sensors, a map of the alphabet associated, and the task character. Testing sentences were typed in Word, with limited visual feedback, using non-predictive typing (map of characters in alphabetic order associated to sensors) and predictive typing (LetterWise) for TCS keyboard, and non-predictive typing for TCS mouse. Two subjects participated for four and three consecutive days, respectively, two sessions per day. Maximal throughput of 2.94, 2.46, and 2.06, 1.68 [cwpm] were obtained with TCS keyboard by subject 1 and 2 with predictive and non-predictive typing respectively. Maximal throughput of 2.09 and 1.71 [cwpm] was obtained with TCS mouse by subject 1 and 2, respectively. Same experimental protocol has been planned for a larger number of subjects.
对一种无线集成舌控制系统（TCS）提供的全字母键盘和操纵杆式鼠标（配有屏幕键盘）的打字性能进行了研究。速度和准确性以吞吐量的形式进行测量，吞吐量定义为每分钟真正正确的单词数[cwpm]。训练字符序列在一个专用界面中输入，该界面提供激活传感器的视觉反馈、相关字母表的映射以及任务字符。测试句子在Word中输入，视觉反馈有限，TCS键盘使用非预测性打字（按字母顺序与传感器关联的字符映射）和预测性打字（LetterWise），TCS鼠标使用非预测性打字。两名受试者分别连续四天和三天参与，每天进行两次测试。受试者1和受试者2使用TCS键盘进行预测性打字和非预测性打字时，最大吞吐量分别为2.94、2.46和2.06、1.68[cwpm]。受试者1和受试者2使用TCS鼠标时，最大吞吐量分别为2.09和1.71[cwpm]。已为更多受试者制定了相同的实验方案。
