communicate with locked-in, ALS
Good morning everyone!
My name is Nicola (from Italy) and I started to get interested in EEG projects to look for a solution to communicate with my mother, who is sick with ALS (amyotrophic lateral sclerosis) and now in total lock-in (inability to communicate by any means, even with optical communicators as she did until recently).
So I started looking for alternative solutions that would allow at least a YES/NO communication.
I don't have great skills in the field, but I have always been passionate about computer science and electronics in general. A first project was to use a Neurosky EEG headset (taken from the game Star Wars - The Force Trainer II) connecting it to an Arduino board to detect a signal that could somehow be associated with YES/NO. The problem is that this type of headset, very basic, allows only to detect a signal when there is brain activity in general and this makes it difficult to associate, for example, the presence of signal with the YES and the absence with the NO.
As a total ignorant in the field, I am wondering if the boards with multiple channels are able to detect different types of brain waves (I make an example, perhaps silly, to make the idea: thinking about good things activates a type of wave, thinking about bad things activates another type of wave). This would allow to associate the two types of waves to YES and NO.
Can you give me some more information about this?
On the OpenBCI site I see that there are different types of boards based on the number of channels.
- Ganglion Board (4-channels)
- Cyton Biosensing Board (8-channels)
- Cyton + Daisy Biosensing Boards (16-channels)
Would any of these work for my "project"? I don't know if I managed to explain my problem, please ask me any questions that may be helpful to understand better.
Thank you all very much!
