TouchingSpace利用触控板将地图渲染为有界区域，结合音频、触觉与对话代理，帮助盲人和低视力用户自主探索空间，提升出行前理解。
AI 中文摘要
现有的无障碍地图系统要么通过手部探索布局，要么通过语音传递信息；很少有系统将两者结合起来，以支持盲人和低视力（BLV）人群在出行前的空间理解。我们提出了TouchingSpace：一个系统，它检索室外场所的地图数据，并将其周围环境渲染为固定触控板位置上的有界区域。在探索过程中，用户会收到音频和触觉反馈，并可以向对话代理提出开放式问题。我们进行了一项用户研究，有十四名BLV参与者使用TouchingSpace探索了一个场所，并反思了这种体验。我们发现，参与者使用声音和振动来定位场所，使用语音来识别和描述它们；有界表面支持用手进行发现、修正和空间检查；他们期望这种意识能支持未来的出行。TouchingSpace展示了笔记本电脑触控板如何支持自主的空间探索。这些发现表明，无障碍AI地图应将对话建立在有界、用户可控的空间表面上。
英文摘要
Accessible map systems either make a layout explorable by hand or convey information through speech; few combine both to support pre-travel spatial understanding for blind and low-vision (BLV) people. We present TouchingSpace: a system that retrieves map data for an outdoor place and renders its surroundings as bounded regions at fixed trackpad positions. During exploration, users receive audio and haptic feedback and can ask a conversational agent open-ended questions. We conducted a user study with fourteen BLV participants who explored a place using TouchingSpace and reflected on the experience. We found participants used sound and vibration to locate places and speech to identify and describe them; the bounded surface supported discovery, revision, and spatial checks by hand; they expected this awareness to support future travel. TouchingSpace demonstrates how a laptop trackpad can support self-directed spatial exploration. These findings suggest accessible AI maps should ground conversation on bounded, user-controlled spatial surfaces.
