I never tried those virtual reality helmet games when they were in shopping centres, did not want to look like a dick waving my arms around. But from what I was hearing on the radio the other day, I think a next generation version of virtual reality is about to take off. I expect it to be a dominant form of entertainment within the next decade, that's why I think any attempt at sensory vests for books, will be quickly overtaken by virtual reality. The holodecks are a lot further away, I only see them working with very sophisticated nanoswarms that can instantly create the infrastructure of the virtual scenes someone is seeing, ie, if you see a seat, the nanoswarm creates the framework of a seat for you to sit on. I have always been fascinated by how the holo decks would work.

Now if it were to develop over time, it could be interesting. I think that eventually all of these worlds will merge, where by we will 'visit' holographic worlds where we can interact with 3D humans etc, a bit like the Holo Deck in Next Generation, perhaps wearing some sort of suit, so that we can feel sensations.
Pretty soon we wont have to leave the house or actually interact with 'real' people at all.
