Impact of EEG-Based Virtual Reality Haptic Force Feedback on User Experience

This study investigates the effects of haptic force feedback on brain neurofunctional connectivity and user immersion in virtual reality (VR) rehabilitation training. We used a VR setup with wearable force feedback devices to compare task performance between conditions with force feedback and those without it across different difficulty levels. By collecting Electroencephalography (EEG) signals and subjective data, we gained valuable insights into cognitive and emotional responses. Results showed enhanced neural activity and stronger immersion in the beta and gamma frequency bands under force feedback conditions. Multi-modal stimulation improved cognitive memory and user experience, with effects positively correlated to task difficulty. These findings show that combining natural interactions with our senses can improve virtual reality (VR) training and help develop better rehabilitation methods in the future.
