Haptic Feedback Devices Applied to Various Systems
A system that enables the user to play the role of Zatoichi, a fictional Japanese blind swordmaster. An "ultrasonic wave focusing device" located in front of the user's face emits ultrasound waves in different ways in accordance with the location of the person acting as an "opponent" so that it becomes possible to find the location of the opponent without using the eyes. When the opponent is located to the left, ultrasonic waves come from the left, and vice versa. As the opponent comes closer, the ultrasound waves become stronger. When I used the system, I felt as if wind was blowing to my face and thought it was tickling.
