ReYou technology creates personal audio and vibroacoustic effects based on the user's HRV data in real time.
PPG - photoplethysmogram
BCG - ballistocardiogram
HRV - heart rate variability
Key Features
- 1Any sensors which detect R-R intervals can be used for the input signal. We use PPG and BCG sensors based on proprietary algorithms with 99% accuracy (patented).
- 2User psychophysiological state real-time analysis
- 3Personalized audio and vibroacoustic effects based on the user's current state
- 4Biofeedback helps user to control their current state by managing audio and vibroacoustic effects
- 5Generative audio and vibroacoustic content rooted in biophilic design
How it Works
Sensors (PPG — photoplethysmogram, BCG — ballistocardiogram) detect heart rate variability (R-R intervals).
Process the data (rhythmogram).
To analyze the data we rely on Heart Rate Variability Standards of Measurement, Physiological Interpretation, and Clinical Use by European Society of Cardiology and the North American Society of Pacing and Electrophysiology.
Identify the part of the autonomic nervous system responsible for your heart function and overall state.
Autonomic nervous system consists of two branches — sympathetic and parasympathetic. The sympathetic branch stimulates your heart activity, while the parasympathetic branch calms it down.
To rest and relax we rely on the parasympathetic branch of the autonomic nervous system.
When analyzing the rhythmogram we look for the components linked to the activity of the parasympathetic nervous system, and depending on the intensity of these components, generate auditory and vibroacoustic stimuli.
The sound stimuli include nature sounds and textures (biophilic design). The audio is recorded using binaural microphones to create a surround sound effect. This technique makes for a truly immersive and relaxing listening experience.
The more relaxed you are, the more vivid and detailed the sounds become.

In Terms of Science
Biophilic design
The premise of biophilia is based on the hypothesis that the environment full of natural landscapes reduces stress, improves concentration and focus.
It is noted that both direct and indirect interaction with elements of nature exerts a positive impact on the cognitive and psychophysiological state of a person, promotes recovery after stress and reduces fatigue [1, 2, 3].

Biofeedback
Biofeedback is a technology which provides the user with external feedback about the state of their body and its changes. Biofeedback training implies continuous real-time monitoring of certain physiological parameters and managing them via multimedia, game-centered and other techniques in a given range of values.
When developing our technology, we rely on the heart rate variability training protocol [4, 5, 6]. The main physiological mechanisms which ensure the effectiveness of the training include a set of processes:

- phase relations between heart rate fluctuations and respiration;
- phase relations between heart rate and blood pressure fluctuations;
- baroreflex activity;
- resonant characteristics of the cardiovascular system
