HapReel: A Racket-shaped Haptic Display Controller for Presenting Vibrotactile and Force Feedback through Fingertip Deformation

Racket sports in virtual spaces are rapidly gaining popularity. However, to approximate the real-world experience, particularly when hitting the ball, tactile feedback is crucial. Current feedback is primarily through vibrations and audio, and providing rich tactile feedback typically requires large, heavy devices. This research proposes a method to realize more realistic tactile feedback by presenting force sensations through fingertip deformation using a small device. This novel device has the potential to enable immersive experiences in VR racket sports and aid in the training for racket sports.
