AR (Augmented Reality) & Virtual Reality (VR) applications (apps) tend to be according to computer simulation of real-life scenarios and environments. The simulation will bear a high amount of resemblance with whatever will be depicted from real-life, either graphically or sensorially. The word ‘sensorially’ is broader than ‘graphically’ given it means everything perceptible to the senses I.e. graphics, touch, sound, voice, smell and so forth. Usually, the degree of resemblance with the original needs to be often times higher plus more accurate in the case of VR compared to AR apps.
Think about the video recording of your 100-metre dash from your recent Olympic Games. The initial commentary could possibly be in English therefore, as it’s, that video are not very thank you for visiting in france they. Either changing the commentary to French or adding suitable French sub-titles is likely to make it more fun with a French audience. This, in simple terms, is how AR finds its opportunity – augmenting the original with additional useful info – in our example, substituting French for English and therefore, making the content more valuable for the French-speaking. As the second example, look at the video capture of the road accident. Two cars collide on the highway and one is badly damaged. Police officers is probably not able to pin-point which of the drivers was in charge of the accident just by viewing it. If, however, it 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 possibly be established with near to, maybe, hundred-percent certainty.
VR (Virtual Reality), conversely, is very different from AR. Actually, both the only share one thing in accordance – internet based simulation. As pointed out, the simulation furnished by VR has to be of these good quality that it’s indistinguishable from reality. Theoretically, that is impossible. Therefore, for practical purposes, VR only means a diploma of approximation, sufficient for any user to obtain a ‘live’ example of the simulated environment. Moreover, VR is interactive and responds sensorially, in ‘real-time’, and merely such as real-life e.g. in the VR application, imagine you’re 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 a close place. You then throw a lighted match-stick about the pile… it will respond immediately showing a robust, quickly spreading fire burning on the pile, its shape occasionally altered by the blowing wind… so that as in real-life… the fox (scared with the fire), must back off? – and it does! The device may let you change the direction, speed and alteration in the speed from the blowing wind, angle of throw of the match-stick etc. and the system will respond using the new results immediately! Thus, VR enables one to try out real-life scenarios and obtain sufficiently accurate results equally as though he/she were from the desired environment/ place, face-to-face, but not waste time, travel & resource costs etc.
VR applications consume awesome quantities of computing power. When compared, AR applications are certainly not in any respect demanding on resources – AR applications run comfortably on mobile phones, tablets, other hand-helds, laptops and desktops. Very probably, you use a few AR apps on your Android/ iOS device, right now, with no knowledge of it! (e.g. Wordlens, Wikitude World Browser etc.).
The explanation for the main difference is VR apps first must correctly interpret whatever action the user performed then ‘make out’ the proper response that the real environment would return, full of animated graphics, movements within the right directions, sounds and so on and in addition, as per correct physics, math and then any other sciences involved. Most of all, ‘latency’, or perhaps the response time from your application, must be sufficiently high. If not, the user, who’s have understandably high expectations, will certainly 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!’. In order to avoid 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. Which explains, why.
