Dynamic Brake Control for a Wearable Impulsive Force Display by a String and a Brake System

In recent years, it has become possible to experience sports in the virtual reality (VR) space. Although many haptic displays in the VR environment currently use vibrators as the mainstream, the vibrators’ presentation is not suitable to express ball-receiving in the VR sports experience. Therefore, we have developed a novel haptic display that reproduces an impulsive force by instantaneously applying traction to the palm using a string and wearable brake system. This paper proposes a method to present various reaction forces by dynamic control of the braking system and report the quantitative evaluation of the device’s physical and psychological usability.
