We propose SolefulTap for a novel tap dancing experience. It allows users to feel as if they are tap dancing or appreciate a tap dancing performance using the sensations of their own feet. SolefulTap uses a method called Step Augmentation that provides audio-haptic feedback to users, generating impacts in response to users' simple step motions. Our prototype uses a floor-type impact display consisting of pressure sensors, which detect users' steps, and solenoids, which generate feedback through impact. Through a preliminary user study, we confirmed that the system can provide untrained users with the experience of tap dancing. This study serves as a case study that provides insight into how a reactive environment can affect the human capabilities of physical expression and the sensation experienced.

翻译：我们提出SolefulTap，旨在提供一种新颖的踢踏舞体验。该系统使用户能够通过自身足部感知，体验宛如正在表演踢踏舞或欣赏踢踏舞演出的感受。SolefulTap采用名为"步态增强"（Step Augmentation）的方法，通过向用户提供音频-触觉反馈，根据用户简单的踏步动作生成相应的冲击响应。我们的原型系统采用地板式触感显示装置，该装置由用于检测用户踏步动作的压力传感器和通过冲击产生反馈的螺线管组成。初步用户研究表明，该系统能够为未经训练的参与者提供踢踏舞体验。本研究作为一项案例研究，深入探讨了反应式环境如何影响人体物理表达能力及感知体验。
