First read about this on the Detective Marketing blog. A mindblowing presentation about a experement where they try widghen the senses. With just a couple of bucks almost anyone can buy and make those devices. Those new devices probably wont be out for commercial use for some years (or maybe they will be in one form or another).
But whats more interesting is what entrepenures and scientists will develop for new unthinkalbe uses. Better yet, in the hands of really creative game designers a new way of playing games will emerge. The possibilities are endless!
