“Developing Brain Computer Music interfaces for Meditation” was the topic of Krisztiáns PhD thesis, as shown in the following YouTube demonstration:
The real-time graphs of OpenBCI with OpenBCI GUI which shows alpha waves during listening to music is impressive. Unfortunately, we did not jet find any confirmation that the Greentek Gelfree cap is helpful as a tool for meditation pracititioners to use it on a daily basis. Eventually, the EEG cap needs to be replaced by another one.
We did not study Krisztián Hofstädters PhD. Thesis in detail. But we have studied intensely the subject EEG devices and meditation in our journal. The demonstration shown above gives at first sight the impression that his OpenBCI setup with Greentek Gelfree EEG cap is suitable for practitioners of meditation. But if we have a closer look at the demonstration, we see that only 2 channels of EEG are recorded. For only 2 channels, no EEG cap is necessary. The Muse headband with the Mind Monitor app offers 4 EEG channels and shows alpha brain waves as well. We do not know of anyone else who has demonstrated the Greentek Gelfree EEG cap is suitable for practitioners of meditation.
In the OpenBCI forum, we can find users who bought the Greentek Gelfree EEG cap. But are not most of the users in the OpenBCI forum beginners with beginner questions? We do not know of any other projects than those of Krisztián Hofstädter who uses the Greentek EEG cap and shows brain data, expept from a YouTube video demo of MbrrainTrain.
