We would have to take a second look at the first paragraph of this article to get a hint. Today VR would be best described as a computer technology that uses Virtual reality headsets. Depending on the intended degree of experience, it can be combined with physical spaces, multi-projected environments and other physical peripherals.<\/p>\n

These are combined in order to give the illusion of realistic images, sounds and other sensations that immerse the user into the virtual environment. Some of these hardware inclusions can pass additional signals such as vibrations and these devices are called haptic devices. It may also be known as as force feedback especially when it comes to medical, video gaming and military training applications.<\/p>\n

These environments allow the user to look around the scene, interact with actors in the environment using hand held devices, treadmills and other similar forms of hardware.<\/p>\n

With virtual reality one can also interact over distances such as through remote communication environments which makes telepresence and telexistence possible.<\/p>\n

Now that we has a respectable understanding of what virtual reality is, let see the areas where humans have found some use for this technology whether its life saving or just an excuse to kill time.<\/p>\n
