AR (Augmented Reality) & Virtual Reality (VR) applications (apps) are generally depending on computer simulation of real-life scenarios and environments. The simulation will bear a higher amount of resemblance with whatever is being depicted from real-life, either graphically or sensorially. The definition of ‘sensorially’ is broader than ‘graphically’ because it means all things perceptible to senses I.e. graphics, touch, sound, voice, smell and so on. Usually, the degree of resemblance with the original must be many times higher plus more accurate when it comes to VR than in AR apps.
Consider the video recording of your 100-metre dash from your recent Olympic Games. The initial commentary may be in English and if so, as it’s, that video are not very welcome to french. Either changing the commentary to French or adding suitable French sub-titles can make it more fulfilling with a French audience. This, in essence, is when AR finds its opportunity – augmenting the original with increased useful info – in our example, substituting French for English and as a consequence, making this content more vital to the French-speaking. As another example, think about the video capture of the road accident. Two cars collide on a highway and something is badly damaged. Police officers is probably not capable to pin-point which of the drivers was responsible for the accident by merely viewing the video. If, however, the video was pre-processed by an AR application that added mass, speed and direction info. with the cars on the video, then, the one responsible could possibly be established with near, maybe, hundred-percent certainty.
VR (Virtual Reality), alternatively, is quite distinctive from AR. The truth is, both only share one thing in keeping – internet based simulation. As stated before, the simulation furnished by VR has to be for these high quality that it must be indistinguishable from reality. Theoretically, this can be impossible. Therefore, for practical purposes, VR only means a degree of approximation, sufficient for the user to obtain a ‘live’ connection with the simulated environment. Moreover, VR is interactive and responds sensorially, in ‘real-time’, and just such as real-life e.g. within a VR application, imagine you’re in a forest, about to burn a pile of cut-down bushes and dry leaves. You douse the pile with gasoline. A fox is keenly watching you an area place. Then you definitely throw a lighted match-stick onto the pile… it will respond immediately showing a robust, quickly spreading fire burning about the pile, its shape occasionally altered from the blowing wind… in addition to being in real-life… the fox (scared through the fire), must back off? – plus it does! The system may permit you to customize the direction, speed and alteration from the speed with the the wind, angle of throw of the match-stick etc. and also the system will respond with the new results immediately! Thus, VR enables one to experiment with real-life scenarios and acquire sufficiently accurate results just as though he/she were from the desired environment/ place, directly, but saving time, travel & resource costs etc.
VR applications consume awesome amounts of computing power. When compared, AR applications are not in any respect demanding on resources – AR applications run comfortably on mobiles, tablets, other hand-helds, laptops and desktops. Very probably, you’re using a few AR apps in your Android/ iOS device, right now, without knowing it! (e.g. Wordlens, Wikitude World Browser etc.).
The reason behind the difference is VR apps first should correctly interpret whatever action the person performed then ‘make out’ the appropriate response that the real environment would return, detailed with animation, movements inside the right directions, sounds and so forth and also, depending on correct physics, math and then any other sciences involved. Most importantly, ‘latency’, or the response time from the application, must be sufficiently high. Otherwise, an individual, who’s feature understandably high expectations, is sure to get so completely put-off that he/she might burst by helping cover their a string of unprintable words towards the effect "to hell using this type of dumb thing!’. To stop such failures, a computer (or network of computers) designed with unusually powerful mobile processors, high-fidelity graphics software, precision motion trackers and advanced optics, is needed. And that explains, why.
