力反馈鼠标的推出，通过力输出提供高保真触觉提示，可能代表了定点设备设计中期待已久的技术突破。然而，很少有研究探讨力反馈对于台式计算机人机界面的好处。十名成年人执行了八十项转向任务，参与者使用传统的力反馈鼠标将光标移动通过具有不同难度指数的小隧道。对于力反馈条件，鼠标显示将光标拉至隧道中心的力。这些任务需要光标在水平和垂直屏幕上移动。与传统鼠标相比，在力反馈条件下，移动时间平均快 52%。此外，对于传统的鼠标垂直移动来说，比水平屏幕移动需要更多的时间来完成。另外十名成年人完成了组合转向和瞄准任务，参与者导航穿过隧道，然后单击隧道尽头的一个小盒子。力反馈再次缩短了完成任务的时间。尽管移动时间比纯转向任务慢，但转向难度指数主导了转向目标关系。这些结果进一步支持人机界面受益于人类用户的触觉提示的额外感官输入。
The introduction of a force-feedback mouse, which provides high fidelity tactile cues via force output, may represent a long-awaited technological breakthrough in pointing device designs. However, there have been few studies examining the benefits of force-feedback for the desktop computer human interface. Ten adults performed eighty steering tasks, where the participants moved the cursor through a small tunnel with varying indices of difficulty using a conventional and force-feedback mouse. For the force-feedback condition, the mouse displayed force that pulled the cursor to the center of the tunnel. The tasks required both horizontal and vertical screen movements of the cursor. Movement times were on average 52 percent faster during the force-feedback condition when compared to the conventional mouse. Furthermore, for the conventional mouse vertical movements required more time to complete than horizontal screen movements. Another ten adults completed a combined steering and targeting task, where the participants navigated through a tunnel and then clicked a small box at the end of the tunnel. Again, force-feedback improved times to complete the task. Although movement times were slower than the pure steering task, the steering index of difficulty dominated the steering-targeting relationship. These results further support that human computer interfaces benefit from the additional sensory input of tactile cues to the human user.
