Virtual Reality technologies are moving ahead as fast as most of the modern day science like alternative energy, BioTech, Nanotech, Super Computers, or Artificial Intelligence. Not too far off into the future you will be able to sit in your living room and eating your dinner and drinking red wine sitting at Jesus' Last Supper, you'll be able to blast off with the Space Shuttle, watch the Roman Gladiators in a 2200 year old stadium or sit down with the past President of your choice for coffee. All in virtual reality and it will be so real, you'll forget where you actually are.
So, what technologically advanced hardware will you need to accomplish this, what sort of computer hardware will your living room have in it? Well, you'll have a few holographic projection units, several large flat panel screens of very thin material which will double as your wallpaper. You will have a special scent machine that will deliver the aroma that fits the scene; I hope you are not planning on milking cows in your virtual reality living room, peeyooo!
You will also have a modern day sound synthesizer with something similar to today's surround sound units. The first generation of this highly evolved technology will include helmets and a good amount of augmented reality technologies. But the later versions will not require the cumbersome helmet display units. Of course, to truly be authentic, you might want to brush up on your foreign languages, which you can also learn full immersed in the foreign city of your choice while learning at home.
Lastly, you will want to have a cool wardrobe of clothing that can camouflage itself for the scene. Indeed, you will become a character in your own virtual reality movie. You can be anything, go anywhere, live any life, without leaving home. Pretty cool is not it?
