Together with sight and hearing, touch represents a means of communication for human beings. Indeed, the sense of touch is capable of proving a whole non-verbal language that can be developed and offer many more possibilities than traditionally believed. Much of what is found in the literature about tactile communication concerns tactile stimulation of the fingertips and hands. However, as the area of tactile feedback is a ‘hot’ research topic especially in human-computer interaction, other body areas have been explored as well; wrist/forearm [1], abdomen [2], chest [3], tongue [4], ears [5], and head [6] have been studied to transmit information to a user (a comprehensive survey of wearable tactile devices can be found in [7]). Devices are as diverse as the technology used and the location on the body. Yet, the human foot has not received much attention.

与视觉和听觉一起，触觉代表了人类的一种交流方式。事实上，触觉能够证明一种完整的非语言语言，它可以被开发并提供比传统认为的更多的可能性。在有关触觉交流的文献中发现的大部分内容都涉及对指尖和手的触觉刺激。然而，由于触觉反馈领域是一个“热门”研究课题，尤其是在人机交互方面，其他身体领域也得到了探索；手腕/前臂 [1]、腹部 [2]、胸部 [3]、舌头 [4]、耳朵 [5] 和头部 [6] 已被研究向用户传输信息（可穿戴触觉设备的综合调查可以见 [7]）。设备与使用的技术和在身体上的位置一样多样化。然而，
