HeatFlow: A Thermal-Tactile Display for Dynamic 2D Thermal Movements
summary
A wearable grid of nine tactile actuators and one thermal actuator renders moving heat by combining thermal masking with apparent tactile motion, using phantom points, averaged actuator intensities, and a warmup synchronization phase. Three studies with 16 participants each find best continuity around 50 mm/s and 3 cm spacing, hot cues giving strongest flows. The heat flow algorithm outperforms two prior motion methods on 10 geometric patterns and boosts immersion when applied to VR on arm, palm, and face.
