在本文中，我们提出了三个实地评估触觉陆地导航系统。在实验1中，我们从实验室环境过渡到用于训练美国陆军士兵陆地导航的崎岖地形。在这种具有挑战性的地形上航行需要仔细注意周围的环境。参与者使用1)地图和指南针，2)标准的字母数字手持式GPS设备，3)触觉GPS系统，沿着600米的树木茂密的地形导航3个航路点，同时也响应无线电信息请求。实验二在夜间行动中使用了同样具有挑战性的地形，参与者还必须使用1)手持GPS设备，2)基于地图的头戴式GPS和3)触觉GPS系统来搜索活体和轮廓目标。除了导航，参与者还搜索剪影和活人目标。实验3让参与者使用1)商用GPS箭头显示器，2)触觉GPS系统，以及3)两者同时进行导航。我们的结论是，触觉导航显示可以在艰苦的户外环境中使用，并且在高认知和视觉工作量的条件下优于视觉显示。
In this paper, we present three field-based evaluations of a tactile land navigation system. In Experiment 1, we transition from a laboratory setting to rugged terrain used to train US Army soldier land navigation. Navigation in this challenging terrain requires careful attention to one's surroundings. Participants navigated 3 waypoints along 600 meters through heavily wooded terrain, using 1) map and compass, 2) standard alpha-numeric handheld GPS device, and 3) the tactile GPS system, while also responding to radio requests for information. Experiment 2 used the same challenging terrain during night operations, where participants must also search for live and silhouette targets, using 1) handheld GPS device, 2) head-mounted map-based GPS, and 3) the tactile GPS system. In addition to navigating, participants searched for silhouette and live (human) targets. Experiment 3 had participants navigate with 1) a commercial GPS arrow display, 2) the tactile GPS system, and 3) both together. We conclude that tactile navigation displays can be used in strenuous outdoor environments and can outperform visual displays under conditions of high cognitive and visual workload.
