Subject: Where does the future of virtual reality lie?

Would it be practical and possible to someday create a computer program to 
stimulate certain areas in the brain, and read output of the brain to 
create an in-your-mind virtual reality program. For example, the center 
that controls sight can be stimulated to produce images. Would muscle 
functions be able to be read and interrupted? Could touch centers be 
stimulated to create a realistic feeling to the game. Would there be a 
chance of injury such as a coma or brain damage?
