In some prototype mobility aids for the blind information about the environment is obtained with the aid of patterns within a matrix of tactile point stimuli. The aim of this report is to summarize some experiments on the possibilities of guiding movements in 3-D space by devices of this kind, the movements studied being: (1) batting a ball, (2) walking and pointing to a target, and (3) slalom walking. The results were that movements could be guided by such a matrix with reasonable precision and time consumption. There are many remaining problems, especially in a cluttered environment, but they can be expected to be decreased if we are able to increase our knowledge about how touch, or rather the haptic system, is functioning, and if we can utilize this knowledge in constructing more effective tactile displays.
在一些为盲人设计的原型移动辅助设备中，通过触觉点刺激矩阵内的图案来获取有关环境的信息。本报告的目的是总结一些关于此类设备在三维空间中引导运动可能性的实验，所研究的运动包括：（1）击球，（2）行走并指向目标，以及（3）障碍滑雪行走。结果表明，这样的矩阵能够以合理的精度和时间消耗来引导运动。仍然存在许多问题，尤其是在杂乱的环境中，但如果我们能够增加对触觉，或者更确切地说是触觉系统如何运作的了解，并且如果我们能够在构建更有效的触觉显示器时利用这些知识，那么这些问题有望减少。
