Mind Game - Help?

Hey, I'm sure many of you have seen that new game which involves using ekg/eeg sensors and a ball, wherebuy 2 people sitting opposite to each other will try to still their mental acitivity and win the game. The ball will move towards the person who has his mind most at ease.

I'm trying to replicate this in C51, but haven't found any material to help me, except an EKG schematic without any guidance on how to make the sensors.

I hope you guys can help me create a replica, hopefully to allow others to innovate on the game by making other types of games using the same concept as well as allowing people with less money to be able to have a bit of mental fun.

I'm sure many of you are also interested in this, and if we can work together, we can create a DIY guide for this game and also use the concept for other purposes, e.g. mind training applications etc.

Hope someone can help me.

Thanks

  • I hope you guys can help me create a replica,

    Well, do you want a game based on actual physiological principles, or will a random number generator do?

    The latter is trivial, the former is a truly complex task that a C51 is probably unsuited for. And getting the firmware right will be the _smallest_ problem, since the analog side of measuring physiological signals is far from simple - it's about things like:

    - proper interfacing to the body
    - safety(!!!, you're planning to hook up things to a real, life human, right?)
    - signal quality (electrical signals coming from the body are _tiny_, you'll need a precision at least in the ~10 uV range for a useful ECG, and you'll probably be dealing with microvolts (or even fractions thereof) if you want to do an EEG)

    and probably a bunch of other things that even I don't know about since they're handled by the hardware engineer and not the firmware guy (me).
