Yeah, I saw that article in today's newspaper.

I'm more excited by the possible medical uses for the idea that Sony has just patented. Imagine how useful it would be for people who've permanently lost any of their senses.

I hope Sony actually takes serious steps to develop this idea, though. It'd be terrible if the concept just sat on a shelf and rotted, because no-one could be bothered risking a lawsuit from Sony by developing it themselves.

Totally immersive games would be wonderful, but potentially very dangerous. There could be very nasty side-effects from experiencing a totally lifelike, completely palpable war, survival horror or crime simulator.
Also, what happens when someone goes one step further and adds a pain sensation?

Many possibilities.
On another note, there is speculation (not official) that Nintendo will be incorporating some form of brain interface with the 'Revolution', that will allow players to controll the games with their minds. ^__^ lol
This technology already exists, and is used in some hospitals. Physically disabled patients can use their minds to move a cursor around a screen and select various options. Wonderful stuff.
