为了让视力受损的人能够访问图形信息，我们以前开发了一种称为“触觉鼠标”的设备。它由一个电脑鼠标和一个小的触觉显示器组成。触觉信息根据鼠标的动作反馈到手指，给用户探索有形绘图的感觉。然而，由于触觉显示器很小，当用户移动鼠标太多时，他们往往会偏离有形的图形。为了确定减少这种偏差的条件，我们进行了两个实验：一个是在线跟踪，一个是形状识别。我们发现，当被称为“手移动到针比”的参数太低时，偏差的机会增加，而当它太高时，识别失败更频繁地发生。因此，中间条件，导致较少的偏差和较少的歧视失败被认为是足够的触觉鼠标的有效使用。
To provide visually-impaired people access to graphical information, we previously developed a device called a “tactile mouse.” It consists of a computer mouse and a small tactile display. Tactile information is fed back to the fingers according to the mouse's movements, giving the user the feeling of exploring tangible drawings. Because the tactile display is small, however, users tend to deviate from the tangible graphics when they move the mouse too much. To identify conditions for reducing this deviation, we conducted two experiments : one on line following and one on shape discrimination. We found that when the parameter called “hand-movement-to-pin ratio” was too low, the chances of deviation increased, and when it was too high, discrimination failures occurred more frequently. Consequently, intermediate conditions that led to less deviation and fewer discrimination failures were found to be adequate for the efficient use of the tactile mouse.
