@gregward44, did you try contacting Conscious Labs at the links I gave on September 18? Their speller uses a computer monitor screen with flickering labels for the alphabet letters / numbers. The EEG

Yes, here is a commercial speller based on OpenBCI hardware. I'm unclear the current status or pricing, you can contact them.

The research was conducted by a team from The University of Essex. I do not know the specification of the eeg cap or the signal amplifier that was used but I do know that they were using a “speller” s

PS I would like to say to you because I think that for Laura the EMG (neurofly) solution could be better: with the P300 speller but also with a VEP speller Laura has to look at the screen for a lot

re: P300 spellers

In the last years I tried to use EEG (p300 speller + Cyton board and your cap and electrodes) to facilitate the communication to my daughter (she is a disabled girl). I got a lot of problems becaus

Thinkpulse electrode 'probably' works without any wetting, since he offers a package including MindAffect speller and his custom headset.

It is recommended to use wet type electrodes, tutorials covers this. ThinkPulse actives 'probably' work, since Conscious Labs offers a similar cVEP speller package.

may differ for visual P300 tasks, such as your speller question."

One hypothesis may be that auditory P300 signal origins may be closer to the cEEGrid sites, but that this may differ for visual P300 tasks, such as your speller question.

I read on your website something about your cEEGrid. Do you think that is it possible to use cEEGrid with a P300 speller?

thank you for your organizing the discussion! (I wrote some comments about ThinkPulse in this forum inside a discussion about “issues with my 2 Cyton dongles / speller apps [resolved]))";

About 18 months ago in this forum I posed the problem of ThinkPulse sensors+Ultracortex Mark IV + Cyton not working while the Cap with wet electrodes + Cyton worked very well (BCI P300 speller applica

I'm confused about this. I observed artifacts when I was using the simple photoresistor. I am using it as an external trigger for synchronization in a traditional p300 matrix speller to mark on/off wh
