Hapto-Band: Wristband Haptic Device Conveying Information

摘要

We have developed a wristband haptic device called Hapto-band to intuitively convey various pieces of information such as ball direction and player actions in sports. Hapto-band has the advantage that it keeps both hands free and puts less burden on the user's body even when enjoying content for a long time. This device has four vibration actuators that are controlled wirelessly. When the user wears Hapto-band on the wrist, the four vibration actuators are in contact with four positions of the wrist, and various pieces of information can be conveyed by changing the vibration position and the vibration type. In this study, we developed a demonstration system to communicate information about player actions, such as serving/receiving, and the trajectory of the ball in volleyball games to the user via tactile sense by using Hapto-band, and we conducted an experiment to evaluate the effectiveness of using this device to convey player actions in sports.
