Návrh a implementace biofeedbackových her založených na měření variability srdečního rytmu

Abstract

This bachelor thesis focuses on the design and implementation of biofeedback-based games using heart rate variability. The aim of the work is to develop a system capable of acquiring physiological data from a Bluetooth Low Energy device, processing them in real time, and using them to control game mechanics. The thesis introduces the theoretical background of biofeedback and HRV, including the principles of the autonomic nervous system. It also addresses communication with the sensing device and processing of RR intervals, including filtering and computation of time-domain and frequency-domain metrics. The work includes the design and implementation of several games that use the player's physiological state as input, as well as a visualization method for biofeedback. The functionality of the system was experimentally evaluated, and the results indicate that the proposed solution is capable of reflecting changes in the user's physiological state within the game environment.
