Complex biofeedback for vision correction “Biosvyaz”
The BFB software and indicator complex registers and processes several signals of electrical activity of the brain (EEG), respiratory rate (RR) and heart rate (HR). The program evaluates visual acuity for the right and left eyes and, based on the results, determines for the biofeedback instructor the tactics for developing the skill of effortless vision using the biofeedback method. Individual rhythms (alpha, beta, theta) are isolated from EEG signals and biofeedback signals are generated corresponding to changes in the intensity or time of presence of the selected rhythms. The program divides the processed information onto two computer monitors. One monitor (the trainee's monitor) receives information about changes in the processed bioelectric signals with indication of these changes in the form of biofeedback (BFB), and the second monitor (the instructor's monitor) receives information about the results of statistical processing of these signals. BFB signals are presented visually on the computer monitor screen (changes in the brightness of video clips, curtain movement, animated game scenes, changing slides, etc.), as well as in the form of audio signals (threshold on/off, change in tone, etc.). The software of the complex selects individual rhythms through several EEG channels with subsequent processing of the EEG pattern, RR, current heart rate, as well as comparison of the processed signals with reference characteristics, on the basis of which multimedia BFB signals are generated, reflecting deviations of real indicators from the reference ones. The complex provides assessment of the quality of vision in the initial state before the start of training sessions with biofeedback and at various stages of developing the skill of effortless vision, subsequent processing of these results with the issuance of recommendations that determine the strategy and tactics of conducting biofeedback training sessions aimed at improving vision function.
