Demonstration of JetController: High-speed Ungrounded Force Feedback Controllers Using Air Propulsion Jets

Abstract

JetController is a novel haptic technology capable of supporting high-speed and persistent 3-DoF ungrounded force feedback. It uses high-speed pneumatic solenoid valves to modulate compressed air to achieve 20-50Hz of full impulses at 4.0-1.0N and combines multiple air propulsion jets to generate 3-DoF force feedback. Compared to propeller-based approaches, JetController is more than 10 times faster in impulse frequency, and its handheld device is significantly lighter and more compact. JetController supports a wide range of haptic events in games and VR experiences, from firing automatic weapons in games like Halo to cutting fruits in Fruit Ninja. To discuss the differences between JetController and vibrotactile feedback approaches, we designed a new prototype based on PS5 Controller, DualSense [1]. There are three haptic approaches in our demonstration, JetController, Adaptive Trigger, and regular vibration feedback. We provide two scenarios, driving with tactile (surface texture) feedback and shooting with recoil feedback.
