Mental State Recognition
Promoting Relaxation by Real-Time Mental State Recognition
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. For this reason, we propose a virtual reality experience that integrates a wearable, low-cost EEG headband and an olfactory necklace that passively promotes relaxation.
Due to the increasing quality and availability of low-cost EEG systems they can be applied in such a scenario to measure the current level of relaxation. Therefore, we introduce new algorithms for real-time mental state recognition based on an entropy-based signal processing approach.
