   brainwave controled robot in robot magazine this month.
   It is interesting the article doen't say much how it works.
   The references at the end of the article are to 2 youtube videos on it you can see how that is hard to search information.
   The students presentation on it is interesting.
   Is their any documentation on the processing methods they used to catagorise the signals into up down left right or forward backward right twist left twist.
   It could be fun to add a A , & B button option to play some retro nintendo games.

   So I think they used a statistics method to work with the sensor data on the laptop does anyone know what they used I was looking into blind signal seperation that is otherwise known as the cocktail party problem. It seperates signals to see the indivigual components without knowing more info about the mixture of signals.

   is it this:

   You can see the labs publications here:

   The paper describing how they go from eeg to motor control is here:

   Cool lab for sure.

   ACTIVATION OF A MOBILE ROBOT THROUGH A BRAIN COMPUTER INTERFACE

   When to replace the keyboard
   —by Kevin M. Berry

   Here is the information from robot magazines table of contents I will check to see if I can find that link they were both youtube. The person who did it gave a presentation the other was a demonstration video.

   Those are still very interesting links thow! Thanks!

   Well I found some C programming code that was for blind source separation that is a attempt at solving the cocktail party problem. It separates mixed signals into their components for example would allow the system to see 1 muscle units signal.

   Well I looked through more of the video and it seperates the signals using wavelets transform.

   Here is the link for BSS C code: http://perso.telecom-paristech.fr/~cardoso/guidesepsou.html

   it compiled and ran on my laptop using gcc.

   Now blind signal separation BSS takes apart the mixed signals and gives back the original signals. Now I can not fallow how it does that but here is C code that has been ported many times to different slower math orented languages like R or matlab.

   But you can see how if the sensors have a high speed link to a pc running the signal separation program located here.

   Then sensors placed on the arm like a blood pressure cuff might see the individual motor signals motor units from the separated signals.

   I hope to have it done by next year but I will drink some more coffee and try for the end of the week poslathian. :)
