我们提出了一种概念验证触觉设备，旨在为坐着的人提供触觉提示，以模拟行走的感觉。通过利用行走的周期性，该设备使用凸轮将马达的旋转运动转换为脚底的周期性压力变化。凸轮从动件装置驱动一组上下移动的板，按压脚底以产生所需的力模式。利用实际的行走压力分布数据设计了凸轮型线。描述用户行走的活动虚拟环境被耦合到系统，以与在虚拟环境中采取的脚步一起显示脚底的翻滚感觉。
We present a proof-of-concept haptic device designed to provide a seated person with haptic cues to simulate the sensation of walking. By taking advantage of the cyclic nature of walking, the device uses cams to translate rotational motion from a motor to cyclic pressure variations on the bottom of the foot. The cam-follower arrangement actuates a set of plates that move up and down, pressing on the soles of the feet to generate the required pattern of forces. Cam profiles were designed using actual data of walking pressure distributions. An active virtual environment, depicting the user walking, is coupled to the system to display the rolling sensation on the bottom of the feet in tandem with footsteps taken in the virtual environment.
