摘要
The ability to relax is sometimes challenging to achieve, nevertheless it is extremely important for mental and physical health, particularly to effectively manage stress and anxiety.We propose a virtual reality experience that integrates a wearable, low-cost EEG headband and an olfactory necklace that passively promotes relaxation.The physiological response was measured from the EEG signal.Relaxation scores were computed from EEG frequency bands associated with a relaxed mental state using an entropy-based signal processing approach.The subjective perception of relaxation was determined using a questionnaire.A user study involving 12 subjects showed that the subjective perception of relaxation increased by 26.1 % when using a VR headset with the olfactory necklace, compared to not being exposed to any stimulus.Similarly, the physiological response also increased by 25.0 %.The presented work is the first Virtual Reality Therapy system that uses scent in a wearable manner and proves its effectiveness to increase relaxation in everyday life situations.
