我们介绍NaviRadar：一种用于手机的交互技术，它使用雷达隐喻来传达用户在期望路线上交叉的正确方向。雷达扫描按顺时针方向旋转，触觉反馈提供，每次扫描都清楚地传达用户当前的方向和用户必须行进的方向。在第一项研究中，我们评估了整体概念，并测试了五种不同的触觉模式，通过一个单一的因素来传达两个不同的方向。结果表明，人们能够很容易地理解NaviRadar的概念，并且可以在提供的整个360°的平均偏差中识别出37°的正确方向。第二项研究表明，与口头指令相比，NaviRadar在感知可用性和导航性能方面取得了类似的结果。通过只使用触觉反馈，NaviRadar与现有系统相比具有明显的优势。特别是，导航不需要视觉注意力；因此，它可以用来提高人们对周围环境的认识。此外，缺乏音频注意力使得它可以在嘈杂的环境中使用，或者可以更好地将这种注意力用于导航过程中与他人交谈。
We introduce NaviRadar: an interaction technique for mobile phones that uses a radar metaphor in order to communicate the user's correct direction for crossings along a desired route. A radar sweep rotates clockwise and tactile feedback is provided where each sweep distinctly conveys the user's current direction and the direction in which the user must travel. In a first study, we evaluated the overall concept and tested five different tactile patterns to communicate the two different directions via a single tactor. The results show that people are able to easily understand the NaviRadar concept and can identify the correct direction with a mean deviation of 37° out of the full 360° provided. A second study shows that NaviRadar achieves similar results in terms of perceived usability and navigation performance when compared with spoken instructions. By using only tactile feedback, NaviRadar provides distinct advantages over current systems. In particular, no visual attention is required to navigate; thus, it can be spent on providing greater awareness of one's surroundings. Moreover, the lack of audio attention enables it to be used in noisy environments or this attention can be better spent on talking with others during navigation.
