I think that virtual reality merely allows people to transcend the rules, laws and constraints of our physical work. We are based in the physical world, like you stated “Truth is Truth and reality is reality”, but VR allows us to suspend those realities and explore and learn without those limitations that may be placed on us. Many years ago I went to a VR conference. On company was working on a system where they would take people with a fear of heights and with a helmet and a controller and would have them walk across a bridge to a bar or something. I tried it out, and I tell you even though it was very crude computer generated graphics it felt very real. When your visualand auditory were controlled by the helmet, it felt very real. In my mind I knew it, but my body and senses told me something way different.

The author of this response makes an excellent point about suspending realities to explore and learn. This option (to suspend) is certainly one of the huge advantages of using virtual environments for education, training, support groups, etc.
As an objectivist I would ask: does suspending reality for a while change reality? No. The constructivist in me would say; suspending reality allows us to us the virtual environment to support the construction of meaning on a topic.
