Ocz Nia

[masterg]

Hello,

I am a computer engineering student, this coming semester i am going to be building a handheld gaming device for my project and i thought the NIA would be a different and unique piece of equipment to integrate into a project such as that. I bought one and am seeing how it works on a normal computer, but i was wondering if i could get information on how the signals are passed through the headband itself. The handheld device wouldn't have windows xp, so no driver support or interface and at this point no usb hookups so i was wondering what signals go through the 3 prong headband to send and receive atleast the glance/muscle movements as they seem to be the easiest to intrepret.

If anyone could answer that, it would be much appreciated,

posted this in OCZ forums weeks ago and no responses yet so im trying to expand my basis.put one in OCZ forum here but i figure may have more ppl in tech talk.

I was thinking of buying a NIA a few months back because I thought it would be really interesting piece of equipment to have and possibly hack it/get it to work with linux and some other applications than just games. What I found out when I searched then web was that OCZ had essentially bought/licensed the NIA from some company that made this kind of equipment for disabled people. The hardware itself seems to be rather unsofisticated; The key to the whole thing is the software and the algorithms/heuristics that are used to analyze that signals that the hardware registers. This made me give give up on the NIA.

I recommend that you take a look the following pages if you havn't done so already:

I think it picks up information through the pores on your skin, I thought I remember seeing that somewhere. It has been a long time since I used my NIA though so Im not positive. And ya, glance and muscle movement are definitely easiest. I never got the brain part working right, according to the program my mind is literally incapable of being in a thinking state.

yea, OCZ just told me that the entire system is passive which makes it alot easier. i just need to find out how the different signals are retrieved and sorted out. they are picked up by the nodes and sent into an operational amplifier and polarities are switched and then shipped off to the pic and shift registers but is the brainwaves/muscles sorted out software or hardware side and wtf does this optocoupler do

[EniGmA1987]

I would imagine that the signals are sorted out in software, where it can read the incoming electrical levels and decide whats what.

digital isolator and optocoupler inside, google has a hard time finding the chips let alone datasheets for them >.> even on alldatasheets

thing you would probably be interested regarding brain reading and mind control stuff:
