    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’ because it means all things perceptible to our senses I.e. graphics, touch, sound, voice, smell and so on. Usually, how much resemblance together with the original should be many times higher and much more accurate when it comes to VR than in AR apps.

    Consider the video recording of an 100-metre dash in the recent Olympic Games. The first commentary could possibly be in English therefore, as it’s, that video won’t be very here you are at the French. Either changing the commentary to French or adding suitable French sub-titles could make it more pleasurable into a French audience. This, in simple terms, is how AR finds its opportunity – augmenting the initial with an increase of useful info – in our example, substituting French for English and therefore, making this content more valuable for the French-speaking. As another example, consider the video capture of your road accident. Two cars collide on a highway and one is badly damaged. The police might not be capable of pin-point which of the drivers was to blame for the accident by simply viewing the video. If, however, the recording was pre-processed by an AR application that added mass, speed and direction info. in the cars on the video, then, usually the one responsible could be established with close to, maybe, hundred-percent certainty.

    VR (Virtual Reality), however, is quite different from AR. In reality, the two only share a very important factor in common – internet based simulation. As pointed out above, the simulation given by VR has to be for these top quality that it is indistinguishable from reality. Theoretically, this is impossible. Therefore, for practical purposes, VR only means a diploma of approximation, sufficient for a user to get a ‘live’ connection with the simulated environment. Moreover, VR is interactive and responds sensorially, in ‘real-time’, and simply like real-life e.g. in the VR application, imagine you are in a forest, planning 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 nearby place. Then you throw a lighted match-stick about the pile… the machine will respond immediately showing a robust, quickly spreading fire burning for the pile, its shape occasionally altered through the blowing wind… so when in real-life… the fox (scared by the fire), must hightail it? – also it does! The system may let you alter the direction, speed and alteration within the speed from the the wind, angle of throw of the match-stick etc. and also the system will respond together with the new results immediately! Thus, VR enables you to definitely test out real-life scenarios and have sufficiently accurate results just like though he/she were within the desired environment/ place, directly, but saving time, travel & resource costs etc.

    VR applications consume awesome numbers of computing power. Compared, AR applications aren’t whatsoever demanding on resources – AR applications run comfortably on mobiles, tablets, other hand-helds, laptops and desktops. Very probably, you’re using a couple of AR apps on your Android/ iOS device, today, with no knowledge of it! (e.g. Wordlens, Wikitude World Browser etc.).

    The real reason for the main difference is the fact that VR apps first must correctly interpret whatever action the user performed and then ‘make out’ the proper response that the real environment would return, complete with animated graphics, movements from the right directions, sounds and so on as well as, much like correct physics, math and any other sciences involved. Most of all, ‘latency’, or even the response time through the application, has to be sufficiently high. Or else, the consumer, who’s include understandably high expectations, will certainly get so completely put-off that he/she might burst out with a string of unprintable words for the effect "to hell using this type of dumb thing!’. To avoid such failures, your personal computer (or network of computers) designed with unusually powerful mobile processors, high-fidelity graphics software, precision motion trackers and advanced optics, is essential. Which explains, why.
