SolefulTap: Augmenting Tap Dancing Experience using a Floor-Type Impact Display
share
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.
