Virtual Sophrologist : un système de formation de relaxation par neurofeedback en réalité virtuelle
Relaxation techniques can relieve us from stress, anxiety, pain, and diseases. Many researchers succeed in relaxing subjects by various methods. However, few are concerned about the ability of relaxation. Hence, the main goal of this study is to help people relax faster. We developed a virtual reality neurofeedback relaxation training system, called Virtual Sophrologist, which immerses users in fantastic environments by a Virtual Reality headset, guides users to follow the Sophrology instructions by a female voice, and displays feedback in real time, which is translated from the Meditation Score collected by EEG. To evaluate this system, we recruited 6 subjects to participate in our 8-session relaxation training and collected their subjective data (by self-report) and objective data (by an EEG headset) to measure the psychological level and to calculate the Time Interval to Relaxation that they took to reach the maximum Meditation Score. The results show decreases in Anxiety and Depression Score from the psychological level, a decrease in Time Interval to Relaxation and an increase in the maximum Meditation Score. Therefore, our system will be useful as a training tool for users who need or want to experience a fast and deep relaxation, whenever they need.
