本研究采用描述性个案研究设计，比较受试者使用三种电脑输入设备（舌触键盘、HeadMaster和口腔棒）的表现。样本包括四名严重身体残疾的学生在一所社区大学的自适应计算机班就读。性能检查的组成部分是输入速度，准确性和水平的感知努力。还检查了受试者对每个接口设备的接受程度。 实验结果显示，使用嘴棒的输入速度最快，其次是HeadMaster，然后是舌触键盘。输入的准确性没有显著差异。三名受试者将舌触键盘评定为需要最低的感知用力率，其次是HeadMaster，然后是口腔棒。总体性能不一定影响受试者对器械的可接受性评级。本研究的信息将有助于治疗师评估计算机接口器械对患者的有效性和可取性。
This research employed a descriptive case study design to compare subjects' performance using three computer input devices: the Tongue Touch Keypad, the HeadMaster, and the mouthstick. The sample consisted of four students with severe physical disabilities enrolled in an adaptive computer class at a community college. Components of performance examined were input speed, accuracy, and level of perceived exertion. Subjects' acceptance of each of the interface devices was also examined. Results showed input speed to be the fastest with the mouthstick, followed by the HeadMaster and then the Tongue Touch Keypad. Accuracy of input did not vary significantly. Three subjects rated the Tongue Touch Keypad as requiring the lowest rate of perceived exertion, followed by the HeadMaster and then the mouthstick. Overall performance did not necessarily affect subjects' acceptability ratings of the devices Information from this study will assist therapists in evaluating the effectiveness and desirability of computer interface devices for patients.
