Pneumatic and acoustic suit: multimodal haptic suit for enhanced virtual reality simulation

Abstract A haptic device provides users with physical feedback to enhance their experience in virtual reality (VR). We developed a multimodal suit, called as Pneumatic and Acoustic (PA) which exhibits high-resolution feedback, applies high pressure realistic vibration user. The PA suit artificially simulates the sensation of brief strong collisions such impact an explosion, ball, or fist. pneumatic actuators, consisting 40 air bladders, are designed bellows-type devices for vertical inflation. bladders placed on chest at equal interval distance 30 mm feedback. acoustic actuators use effective sound signal collision similar vibrations. This study aims examine effectiveness our improving VR users. recognition tests clearly show that participants distinguish between patterns position collided objects suit. user involving ball shows transmits approximate real artificial Our receiving explosion simulations confirm improves depending types contents. results prove creates distinguishable guiding task powerful hence providing high-quality simulation.
