MotionRing: Creating Illusory Tactile Motion around the Head using 360° Vibrotactile Headbands
summary
A 360° vibrotactile headband uses a 1‑D sparse array of vibration motors to produce apparent tactile motion by timing motor onsets rather than moving parts, demonstrated with 12 and 16 motors and angular speeds of 0.5–4.9 revolutions per second. A perception study maps ISOI thresholds as a function of motor spacing, duration and intensity. Two game demos (teleportation, dodging) show improved directionality and enjoyment versus static or visual feedback and achieve 92% top choice for teleportation.
