This is a hot area. Our last post on the topic was widely posted on about 5,000 blogs including Kotaku. Here, Mike Kenward of Science Business puts a price tag on the wireless human-computer interface of about $5,000. We wonder how quickly these interface devices, which offer potential to aid in recovery from strokes or to assist individuals like Stephen Hawking regain tactile functionality or to narrowcast va RSS to subscribers all over the world on their PC's - will be made into products. For me, I wouldn't bet against some of the companies that have redefined consumer electronics from getting active and making something happen.
