    AR (Augmented Reality) & Virtual Reality (VR) applications (apps) are depending on computer simulation of real-life scenarios and environments. The simulation will bear a top a higher level resemblance with whatever is being depicted from real-life, either graphically or sensorially. The word ‘sensorially’ is broader than ‘graphically’ as it means all things perceptible to senses I.e. graphics, touch, sound, voice, smell and so on. Usually, the quality of resemblance using the original should be often higher and much more accurate regarding VR in comparison to AR apps.

    Consider the video recording of the 100-metre dash through the recent Olympics. The main commentary might be in English and if so, as it’s, that video will not be very welcome to french. Either changing the commentary to French or adding suitable French sub-titles is likely to make it more enjoyable with a French audience. This, in simple terms, is where AR finds its opportunity – augmenting the first with more useful info – within our example, substituting French for English and consequently, making the content worth more on the French-speaking. As another example, think about the video capture of your road accident. Two cars collide on a highway then one is badly damaged. The police is probably not capable of pin-point which of the drivers was to blame for the accident by merely viewing it. If, however, the recording was pre-processed by an AR application that added mass, speed and direction info. with the cars on the video, then, usually the one responsible may be established with near to, maybe, hundred-percent certainty.

    VR (Virtual Reality), on the other hand, is very distinctive from AR. The truth is, the 2 only share one thing in keeping – computer based simulation. As stated before, the simulation furnished by VR must be of which good quality that it’s indistinguishable from reality. Theoretically, this really is impossible. Therefore, for practical purposes, VR only means a qualification of approximation, sufficient for the user to get a ‘live’ connection with the simulated environment. Moreover, VR is interactive and responds sensorially, in ‘real-time’, and simply such as real-life e.g. within a VR application, imagine you have 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 from a close place. Then you throw a lighted match-stick to the pile… the system will respond immediately showing a solid, quickly spreading fire burning for the pile, its shape occasionally altered through the the wind… so when in real-life… the fox (scared with the fire), must try to escape? – and yes it does! The machine may allow you to alter the direction, speed and alteration from the speed of the blowing wind, angle of throw with the match-stick etc. and also the system will respond together with the new results immediately! Thus, VR enables someone to experiment with real-life scenarios and acquire sufficiently accurate results just as though he/she were inside the desired environment/ place, face-to-face, but time savings, travel & resource costs etc.

    VR applications consume awesome numbers of computing power. Compared, AR applications usually are not at all demanding on resources – AR applications run comfortably on mobiles, tablets, other hand-helds, laptops and desktops. Very probably, you use several AR apps on your own Android/ iOS device, right now, lacking the knowledge of it! (e.g. Wordlens, Wikitude World Browser etc.).

    The explanation for the difference is that VR apps first have to correctly interpret whatever action the consumer performed then ‘make out’ the appropriate response that this real environment would return, filled with animation, movements in the right directions, sounds and so on and in addition, as per correct physics, math and any other sciences involved. Most significantly, ‘latency’, or even the response time from the application, has to be sufficiently high. If not, an individual, who has feature understandably high expectations, will most likely get so completely put-off that he/she might burst by helping cover their a string of unprintable words to the effect "to hell with this particular dumb thing!’. In order to avoid such failures, a pc (or network of computers) furnished with unusually powerful mobile processors, high-fidelity graphics software, precision motion trackers and advanced optics, is required. Which explains, why.
