For whom? If you wish to multiply your personal productivity and efficiency, while hoping to get rid of disturbing thoughts that keep you awake at night — the Mind Tracker app and BCI devices are just what you need. How does it work? Neurons constantly generate electrical signals called brain activity waves. The sensors of devices read these waves, and the BCI Mind Tracker app decodes the signal into the metrics easy to understand. We call this the brain control panel. On the one hand, Mind Tracker enables real-time and retrospective analysis of brain activity through convenient dashboards. On the other hand, it serves as a tool for enhancing personal productivity and stress resilience. What can the Mind Tracker do? 1. The BCI Mind Tracker determines the user’s individual Alpha Peak Frequency (iAPF). IAPF is a genetically determined intrinsic feature of brain activity that is responsible for a person’s behavioral pattern It is measured within the frequency of 7 to 13 Hz. Alpha peak is gauged by Mind Tracker in just 2 minutes. iAPF values in Hz determine inclination to certain social roles, such as: - creative people (7–9.5 Hz) - managers (9.5–10.5 Hz) - engineers (10.5–13 Hz) 2. It shows the brain's workload level with tasks in real-time. 3. The tracker identifies the user's current psycho-emotional state: - engagement; - relaxation; - fatigue; - anxiety; - stress. 4 It displays the user's attitude towards the task they are currently solving: the level of focus, calmness, or tension. 5. The Mind Tracker BCI helps to get rid of anxious thoughts and become more emotionally resilient. Emotional resilience is the ability to not react to external irritants. It develops alongside the skill of controlling one's own alpha brainwave rhythm. The Stress Resistance alpha training course with biofeedback helps individuals learn how to control their alpha waves, maintaining a high alpha rhythm frequency during work, learning, or when tackling other complex tasks. 6. The Productivity feature helps establish an individual productive work rhythm. The Mind Tracker BCI app shows when the brain is tired and determines the minimum required time for the brain to return to a productive state. Scientific research: The technology for the Mind Tracker BCI app is based on research of individual Alpha Peak Frequency, the Klimesch fatigue index, and the biotech lab's own scientific developments.
