One of the problems with virtual reality is that it is virtual - the things yopu see and interact with are not really there, so you can't reach out and touch them. Which generally makes most VR experiences pretty passive - even adding a joy stick makes VR more like a game than a simulation. Of course, many companies are working on ways to add touch to virtual objects. One recent company is Dexmo, which adds an exoskeleton to your hands to enable simulated touch. While the set-up looks clunky, the idea that it is recreating the shape and consistency of virtual objects could be very useful in medical, educational, and manufacturing realms, among others. Apparently, no price is given, and the manufacturer wants to wait until VR software begins programming touch into their games and simulations. But this is still one step closer to Star Trek Holodecks (or at least the immersion suits described in Ready Player One).
