定点设备是台式计算机图形用户界面 (GUI) 的重要输入工具，需要精确的电机控制和灵活的使用。触觉力反馈设备为操作员提供触觉提示，为现有的视觉和听觉界面增添触觉。然而，在办公环境中使用力反馈设备的性能增强、舒适度以及可能的肌肉骨骼负荷尚不清楚。假设通过添加力反馈，执行任务的时间以及任务的自我报告的疼痛和不适会得到改善，26 名年龄从 22 岁到 44 岁的人在目标目标周围有或没有吸引力力场的情况下执行了 540 次点击任务。添加力反馈后，点击移动速度大约快 25%（配对 t 检验，p < 0.001）。通过问卷测量，用户感知到的不适和疼痛也随着力反馈的增加而减小（p < 0.001）。然而，随着任务环境中添加额外的分散力场，模拟更真实的工作情况，这种差异会减小。这些结果表明，对于给定的任务，使用力反馈设备可以提高性能，并可能减少使用鼠标期间的肌肉骨骼负荷。这项研究的实际或潜在应用包括人机界面设计，特别是广泛用于图形用户界面的指点设备设计。
Pointing devices, essential input tools for the graphical user interface (GUI) of desktop computers, require precise motor control and dexterity to use. Haptic force-feedback devices provide the human operator with tactile cues, adding the sense of touch to existing visual and auditory interfaces. However, the performance enhancements, comfort, and possible musculoskeletal loading of using a force-feedback device in an office environment are unknown. Hypothesizing that the time to perform a task and the self-reported pain and discomfort of the task improve with the addition of force feedback, 26 people ranging in age from 22 to 44 years performed a point-and-click task 540 times with and without an attractive force field surrounding the desired target. The point-and-click movements were approximately 25% faster with the addition of force feedback (paired t-tests, p < 0.001). Perceived user discomfort and pain, as measured through a questionnaire, were also smaller with the addition of force feedback (p < 0.001). However, this difference decreased as additional distracting force fields were added to the task environment, simulating a more realistic work situation. These results suggest that for a given task, use of a force-feedback device improves performance, and potentially reduces musculoskeletal loading during mouse use. Actual or potential applications of this research include human-computer interface design, specifically that of the pointing device extensively used for the graphical user interface.
