Welcome to the future!
Ever heard of an EEG machine? Try this wiki entry if you haven’t.
EEG’s are used to get an idea about which parts of your brain are active, and how they are active. They are of course extremely low resolution in the sense that out of the billions of neurons crammed in upstairs (or in some of our cases, hundreds of millions), EEG’s record at most about 50 summary signals.
Microsoft and a host of others are trying to pair EEG’s up with various tasks like categorizing pictures, robot control and eventually transcribing thoughts to writing.
But perhaps the best part about EEG’s, or maybe just the internet, is that they can be built by the average (and slightly nutty) enthusiast.
Looks like I’ve found another project to work on after I finish my 100 watt CO2 laser CNC cutter!
