VibroMap: Understanding the Spacing of Vibrotactile Actuators across the Body
summary
Two controlled experiments map minimum and maximum inter-motor distances for vibrotactile arrays using ERM vibration motors mounted on cloth, tested at seven body locations (wrist, forearm, upper arm, back, torso/stomach, thigh, leg) in transverse and longitudinal orientations with 24 participants. An adaptive one-up one-down staircase finds threshold distances for phantom continuity; a localization task measures error. Results show the wrist has the tightest spacing, the back the largest, the stomach yields the worst localization, and transverse orientation supports smaller spacing and better localization.
