In this paper, we present Synesthesia Wear, a full-body, customizable haptic interface, and demonstrate its capabilities with an untethered spatial computing experience. This wear not only looks as flexible as ordinary cloth, but also the attached modules are powered and controlled through this conductive textile via two-dimensional signal transmission(2DST) technology. The haptic modules have a pin, badge-like connector, and it can be freely attached on the conductive textile(Fig.1(b)), enabling users to personally customize the experience to their own liking. This module can render variations of haptic feedback to the torso and all limbs of the body, and visualize representations using LED light patterns. We also designed a spatial computing experience(Fig.1(c)) inspired by the perceptual phenomenon called synesthesia. The system provides an sensory blended experience in which the user walks around freely in real space. The user can interact with real and virtual environments, in a reality-overlapping way by wearing Synesthesia Wear.
