Supplementary Material for "Modular tacTiles for Sonic Interactions with Smart Environments"

In this paper, we present a prototype of a spatially resolved force sensing floor surface. The force sensors are based on conductive paper and grouped into modules called tacTiles. Due to the cheap and widely available materials used for tacTiles, the approach is suitable as a low-cost alternative for spatially resolved tactile sensing. The necessary techniques are shared as an open source and open hardware project to provide an affordable tactile sensing for smart environments. As an interactive application of these tacTiles, we present a detection of step direction algorithm used to count steps into and out of a room.

本研究提出一款空间分辨式压力感应地板原型装置。该压力传感器以导电纸为基底，被整合为名为tacTiles的模块化单元。由于tacTiles所使用的材料廉价且易于获取，本方案可作为空间分辨触觉传感的低成本替代方案。相关核心技术以开源软硬件项目的形式公开，旨在为智能环境提供高性价比的触觉传感解决方案。基于上述tacTiles的交互应用场景，本研究提出一款步向检测算法，可统计进出房间的步数。本数据集附带以下展示视频：交互式热图可视化与硬件组件演示视频、搭配外接LED矩阵可视化的监测声化演示视频、监测（步数）声化演示视频以及平衡任务声化演示视频。
