Someday there could be gloves that allow you to feel these "holograms" using cables that prevent your fingers from moving up/down, etc.
I also think this could be a short-term way to introduce full-body physical constraints in full-on virtual reality. (In the more distant future, we will probably know how to stimulate the brain directly to produce these sensations.) I envision a full-body suit (fitted to the user with near perfection) with a bunch of cables going in every direction. So if you try to push a virtual wall, the proper cables will be set to resist. Doesn't seem very practical, but the glove version might be.
