学习一个环境对有视觉障碍的人来说可能是一个挑战。盲文地图允许用户了解一组地点之间的空间关系。然而，实物盲文地图往往价格昂贵，可能并不总是以足够的细节覆盖感兴趣的区域，并且可能无法提供最新信息。我们建立了一个用于表示地理信息的手持系统，称为SpaceSense，它包括定制的空间触觉反馈硬件-连接到移动的触摸屏设备上不同位置的多个振动电机。它通过振动触觉反馈提供有关目的地和书签位置的距离和方向的高级信息，以帮助用户保持这些点之间的空间关系。SpaceSense还采用了一种总结技术，用于公共和商业场所的在线用户评论。我们的用户研究表明，与没有空间触觉反馈的系统相比，使用SpaceSense的参与者可以更准确地建立和维护地图上地点之间的空间关系。他们特别指出，空间触觉反馈是成功建立和维持心理地图的贡献因素。
Learning an environment can be challenging for people with visual impairments. Braille maps allow their users to understand the spatial relationship between a set of places. However, physical Braille maps are often costly, may not always cover an area of interest with sufficient detail, and might not present up-to-date information. We built a handheld system for representing geographical information called SpaceSense, which includes custom spatial tactile feedback hardware-multiple vibration motors attached to different locations on a mobile touch-screen device. It offers high-level information about the distance and direction towards a destination and bookmarked places through vibrotactile feedback to help the user maintain the spatial relationships between these points. SpaceSense also adapts a summarization technique for online user reviews of public and commercial venues. Our user study shows that participants could build and maintain the spatial relationships between places on a map more accurately with SpaceSense compared to a system without spatial tactile feedback. They pointed specifically to having spatial tactile feedback as the contributing factor in successfully building and maintaining their mental map.
