Biofeedback and neurofeedback training utilize real-time monitoring of biological and brain signals to improve concentration, emotional control, reduce stress, and optimize performance. Using specialized sensors, users receive immediate feedback on their physiological state or brain activity and learn to consciously influence these parameters.

Applications include VR and AR, medicine, psychology, sports, education, and mental and relaxation training. It is an effective tool for developing cognitive skills, improving mental health, and increasing performance in work and sports.

EEG (electroencephalography) biosignals are electrical signals generated by the brain that can be measured using specialized sensors and electrodes placed on the scalp. EEG analysis allows for real-time monitoring of brain activity, detecting states of concentration, relaxation, stress, and responses to stimuli.

In VR, AR, neurofeedback, medicine, and scientific research, EEG enables brain-computer interaction, device control, and the optimization of training and therapy. It is a powerful tool for studying brain activity and creating intelligent and personalized experiences using immersive technology.
