Mid-Air Haptics Visualization System Using Augmented Reality Headset and Multiple Ultrasound Transducer Arrays

Augmented reality (AR) is expected to be used in various fields. To achieve highly realistic AR, it is necessary to add other sensations in addition to audiovisual stimuli. Mid-air haptics is an ideal candidate for presenting tactile sensations, but it requires a large-scale system with very many channels. In this paper, we propose a mid-air haptics visualization system using an AR headset and multiple ultrasound transducer arrays. The proposed method can provide a new AR experience that synchronizes a virtual visual object and a virtual tactile object with a small-scale system using consumer products. Finally, we confirmed the effectiveness of the proposed method through evaluation experiments.
