I'm sorry but I have been in recent contact with many people involved
in this project, and in just two words- your wrong.

Here is a correspondence I received from Stuart Dambrot, who has worked
with the prototype:

You couldn't be more incorrect - or misleading - in your response. The 
MindDrive referred to in the initial message (The Other 90 Percent 
Technologies, Sausalito (415) 332-0433) uses an extremely complex 
algorithm to recover far more information than GSR. As I mentioned in my
response to the initial query, I was involved in the announcement and have
worked with the prototype, and it is as far beyond GSR/EEG measurement as 
cellular phones are beyond tin cans-and-string. If this seems a bit 
overreactive, please recall that advances in science and technology are
often stifled or overlooked because of the power of uniformed opinion.

It doesn't use traditoinal EEG or galvonic skin response methods to read
you electrical field.  It works far faster. By the way I listed the number
of the company in the paragraph. If you still don't beleive me call them. 

P.S. I understood that it didn't read your mind in reality, but in practice 
it might as well.
