AttraCar: Multisensory In-Car VR with Thermal, Airflow, and Motion Feedback through Built-In Vehi...
summary
AttraCar repurposes a car’s HVAC and power seat to deliver thermal, airflow, and motion cues, using PWM and CAN control, relay valves, PI loops and K-type sensing, with airflow up to 7.6 m/s, seat travel at 14 mm/s, temperature range 15–50 °C and end-to-end latency ~68 ms. JND tests define four intensity levels, a 24‑participant on‑road study (six feedback conditions, 1.2 km route, 4–5 min scenarios) shows combined feedback maximizes presence and reduces motion sickness, though single modalities like airflow or seat motion already provide most benefits and hot-only thermal cues can increase discomfort.
