Snapshot of some virtual environment where biofeedback has been used. In the environment, we can see the image of the heart and brain with different colours and shapes. The size and the colours of the heart and brain were mapped with the level of arousal. A small pink heart represents a normal condition. However, as the heart rate increases, its colour and size also change in the VR environment. The colour and size of the brain are related to the laterality index
