在这篇文章中，我们描述了两个案例研究，在这些案例中，我们在路点导航任务中测试了触觉躯干显示器。显示器由围绕操作员的腰带上的八个振动元件组成。案例研究都是在振动的工作环境中进行的：一架瞪羚直升机和一艘高速刚性充气船。这两种环境都会导致全身振动，从而干扰显示器上振动信号的感知。振动触觉显示屏通过操作员周围水平面上的局部振动指示下一个路点的方向，并通过所有振动元件同时敲击1秒通过路点。这两个案例研究都表明，显示是直观的：无需培训，两个操作员都可以直接达到高性能水平。此外，尽管全身振动，操作员仍毫不费力地感知到触觉显示。这表明这种创新的显示已经准备好在现实世界中实施。
In this paper we describe two case studies in which we tested a tactile torso display in a waypoint navigation task. The display consisted of eight vibrating elements in a belt around the operator. The case studies were both conducted in a vibrating working environment: a Gazelle helicopter and a high speed rigid inflatable boat. Both environments result in whole body vibrations that can disturb the perception of the vibratory signals on the display. The vibrotactile display indicated the direction to the next waypoint by a localised vibration in the horizontal plane around the operator, and the passage through the waypoint by a 1-second tap by all vibrating elements simultaneously. Both case studies show that the display is intuitive: without training, both operators directly reach high performance levels. Furthermore, the operators had no trouble in perceiving the tactile display despite the whole body vibrations. This indicates that this innovative display is ready to be implemented in real world settings.
