Given these limitations that I see, I have constantly tried to think of ways to remove said limitation given today’s available technologies.  On the physical side of things, I have always wondered how one would move in a virtual environment.  Until this day, the best solution I could think of was some type of platform that was able to move in any direction; this way, the person standing on this platform would always stay in the middle while moving (walking, running, etc.), thereby moving (one’s body) without actually moving (in physical space).  This would allow one to actually walk (while staying in place) without lifting one’s legs in the air and putting them back to “walk in place.”  But then, how would one interact with virtual objects?  Some form of full body tracking seemed to be the answer.  If the entirety of one’s physical body is tracked in real-time, then it is completely possible to duplicate its movements virtually.  Then comes the issue of visual immersion.  Again, constantly staring at one screen is fundamentally insufficient, so how would this be fixed?  The most obvious solution is the creation of a visual display (or a combination of displays) that totally and completely surrounds the user.  I have personally experienced a 360 degrees display that surrounded the audience, and it was incredible.  No matter which way you turned, you were always looking at the environment around you, even if the “action” you were supposed to be looking at was behind you.  However, even this was limited.  Looking up and down provided no visual material.  So while this 360 degrees display was a huge step in the right direction, it still had its issues.  So the next step from here would be to create a display that, not only surrounded the user horizontally, but also vertically.  This way, no matter which way the user turned, there would always be (virtual) visual information to see; there would be nowhere the user could look to see something from the real world that would break the virtual immersion.
           That was the basic setup of how I imagined this piece to work – some mechanism that involved leg movement in order to allow the user to move throughout the virtual world while physically not moving forward/backwards/etc., some kind of body tracking to recreate one’s movements in a virtual world, and some kind of complete (virtual) visual stimulus.
