In the late 1990's, I recall that there was a piece of hardware being demonstrated in Best Buy that supposedly allowed you to control your computer via signals sent from your brain.
The way it worked was that there was a small metallic plate that you would place your finger on. This plate was connected to (I believe) a USB port, and it somehow translated the signals from your brain into "left" and "right" commands for the computer.
In the Best Buy demonstration, the product was hooked up to the slalom game that came with Windows 3.1 or 95 or so; the point was to ski left and right, avoiding trees, and hitting hills of snow to gain points by jumping in the air and doing tricks.
The device somehow detected "brain patterns" and allowed you to ski the courses without actually moving. I remember it being notoriously hard to control at first, but after a few minutes, the brain control seemed natural and intuitive, and it actually made me a bit giddy to see the skier move without any apparent physical movement on my part.
The problem is that I can't seem to find any documentation on this product anywhere. It seemingly had the name "Max" or the like, and I remember spending hours in Best Buy playing it before it mysteriously disappeared and was never seen again.
What was this product, who created it, and why did it mysteriously vanish without a trace? Is it still possible to find/purchase one of these devices, or is the science behind it complete bull? I remember it working pretty well, but the device cost about $300 USD, which was more than you'd pay for a complete game console of the era.
Can anyone shed any light on this product, and what happened to it?
