System Design of Wearable Tactile Device Based on Virtual Reality

Virtual reality technology has brought new experiences to human-computer interaction, while force feedback technology can improve the immersion and realism of virtual contact. Currently, there are some commercial haptic device products on the market, but these devices are commercial and non-open source, and the development technology of haptic devices is confidential. In this paper, a wearable fingertip force feedback glove based on virtual reality is designed. The glove uses a limit on the connecting rod to achieve force feedback on the fingertip, uses a potentiometer sensor as input, uses a motor as output, and uses serial communication between the upper and lower computers. The entire device has low cost and is easy to wear. To verify the effectiveness of this device, a pressure sensor is used to measure the contact force during the interaction process, and the actual measured feedback force is compared with the theoretical feedback force. The experimental results show that the force feedback glove can apply feedback force within the allowable error range, and has good real-time performance.
