Control your TV with just a thought.

Have you ever thought," wouldn't it be cool if i could change the channel just by thinking about it?" well pretty soon you may well be able to.

The "brain-machine interface" developed by Hitachi inc. is the first step. It analyzes slight changes in the brain's blood flow and translates brain motion into electric signals.

Hitachi's scientists are set to develop a brain TV controller letting users turn a TV on and off or switch channels by only thinking. The technology could one day replace remote controls and keyboards.

One advantage to Hitachi's technology is that sensors don't have to physically enter the brain. Earlier technologies developed by U.S. companies like Neural Signals Inc. required implanting a chip under the skull.

Hitachi Inc. is already testing the device by making a model train run just by the persons thoughts. One of the first problems facing the company is the size of the headband, even though there is a prototype compact version, It still weighs a whopping 2 LBS.

This looks like its going to be a great new tech toy, and I for one can't wait for the day I can flip through the channels on my TV without having to look for that darn remote.
