A Buddhist Point of View of Virtual Reality Buddhism teaches that what is real is experience; seeing, hearing, smelling, tasting, feeling, thinking.

From this perspective, is virtual reality, (video games, Oculus Rift, and such) objectively less "real" than reality? One certainly sees, hears, feels and thinks in virtual reality. 

If material objects are not real; are digital images of them any less real?

I suspect there is an objective answer to this from a Buddhist point of view and I'm interested in understanding it.
Gosh, that's a heavy question. All I'll do is point you to some potentially useful material. I suggest you take a look at comparisons between the philosophy of Wittgenstein, and that of Nagarjuna. (Professional analytic philosophers may be knee-jerking like crazy here, but I'll persist.) The central idea that connects them -- if anything does -- is the idea that what you are asking sits outside the bounds of what language can express. It -- the notion of more or less "real"-ness -- is an example of what Wittgenstein referred to in stating "Whereof one cannot speak, thereon one must remain silent."

Or, less exotically, I really do think that the movie "The Matrix" has something to offer here. When Neo asks Morpheus, inside the battle simulation, "So this isn't real?", Morpheus replies "What is real?" Put another way, why are you distinguishing between "virtual" reality, and "real" reality? Ultimately we have no idea what is "out there"; the only thing we do know for sure is that we are perceiving it.

I don't know if that is of any use whatsoever :-)
