A comparison of Auto Train Brain neurofeedback rewarding interfaces in terms of efficacy

- Auto Train Brain is a mobile app that was specifically developed for dyslexic children to increase their reading speed and reading comprehension. In the original mobile app, there was only one unique neurofeedback user interface that provided visually and audibly rewarding feedback to the subject with a red-green colored arrow on the screen. Later on, new modules are added to the app with the requests of the end-users. These are the “youtube” video-based interface, “Spotify” auditory-based interface, and arrow interface which gives visual and auditory cues. In this research, we have compared the efficacy of the neurofeedback rewarding interfaces. The experiment group consists of 20 dyslexic children aged 7-to 10 (15 males, 5 females) who have preferred one interface over the others each day and used it at home for more than six months. The result indicates that though the “youtube” interface is liked most by the participants, the arrow-based simple neurofeedback interface reduces theta brain waves more than other rewarding schemes. On the other hand, “youtube” and “spotify” based interfaces increase Beta band powers more than the arrow interface in the cortex. The ”Spotify” user interface improves the fast brain waves more on the temporal lobes (T7 and T8) as the feedback given was only auditory.
