In this paper, the results of a 2-D center-out task in a Fitts's law experiment have been presented for measuring the performance of the Tongue Drive System (TDS). Although the end-user population for TDS is individuals with tetraplegia, in this study, we recruited 6 able-bodied subjects in 3 sessions, conducted in 3 consecutive days. They performed the same task with their right hand using a standard mouse for achieving a baseline as well as a standard keypad with their right index finger. The resulting average throughput for TDS, keypad, and mouse were 1.67, 2.17, and 3.99 bit/s, respectively.
本文展示了在菲茨定律实验中二维中心向外任务的结果，以测量舌驱动系统（TDS）的性能。尽管TDS的最终用户群体是四肢瘫痪者，但在本研究中，我们连续三天分三个阶段招募了6名身体健全的受试者。他们用右手使用标准鼠标执行相同任务以建立基线，并用右手食指操作标准键盘。TDS、键盘和鼠标的平均吞吐量分别为1.67、2.17和3.99比特/秒。
