Contribution
The paper presents a new wearable haptic device capable of rendering comprehensive torque feedback from any angle, integrating control and handle parts with a string tension mechanism.
Findings
Successfully rendered 360-degree torque feedback in VR demos
Enhanced realism in virtual interactions with the device
Demonstrated effective control of wrist torque sensations
Abstract
Haptic feedback increases the realism of virtual environments. This paper proposes a wearable haptic device that renders torque feedback to the user's wrist from any angle. The device comprises a control part and a handle part. The control part consists of three DC gear motors and a microcontroller, while the handle part securely holds the Oculus Quest 2 right controller. The control part manages string tension to deliver the sensation of torque feedback during interactions with virtual tools or objects. The three points of the handle part are connected to the three motors of the control part via strings, which pull the handle part to render precise 360-degree (yaw and pitch) torque feedback to the user's wrist. Finally, to show the effectiveness of the proposed device, two VR demos were implemented- Shooting Game and Shielding Experience.
