AR (Augmented Reality) & Virtual Reality (VR) applications (apps) tend to be based on computer simulation of real-life scenarios and environments. The simulation will bear a top a higher level resemblance with whatever will be depicted from real-life, either graphically or sensorially. The term 'sensorially' is broader than 'graphically' since it means everything perceptible to senses I.e. graphics, touch, sound, voice, smell etc. Usually, how much resemblance together with the original should be often times higher and more accurate in the matter of VR compared to AR apps.
Look at the videos of your 100-metre dash from your recent Olympics. The first commentary could be in English therefore, since it is, 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 fun to a French audience. This, in essence, is where AR finds its opportunity - augmenting the first with more useful info - within our example, substituting French for English and as a consequence, making the content more vital towards the French-speaking. As the second example, consider the video capture of an road accident. Two cars collide with a highway and one is badly damaged. The authorities may not be in a position to pin-point which of the two drivers was responsible for the accident by merely viewing the playback quality. If, however, the playback quality was pre-processed by an AR application that added mass, speed and direction info. from the cars towards the video, then, the one responsible may be established with near, maybe, hundred-percent certainty.
VR (Virtual Reality), alternatively, is fairly different from AR. In fact, the two only share another thing in keeping - internet based simulation. As pointed out above, the simulation provided by VR has to be of these top quality that it is indistinguishable from reality. Theoretically, this really is impossible. Therefore, for practical purposes, VR only means a diploma of approximation, sufficient for the user to get a 'live' experience 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 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 from a close place. You then throw a lighted match-stick onto the pile... the system will respond immediately showing a powerful, quickly spreading fire burning about the pile, its shape occasionally altered with the breeze... so that as in real-life... the fox (scared from the fire), must try to escape? - and it does! The system may enable you to affect the direction, speed and alteration from the speed from the the wind, angle of throw from the match-stick etc. and the system will respond with the new results immediately! Thus, VR enables anyone to experiment with real-life scenarios and acquire sufficiently accurate results just like though he/she were in the desired environment/ place, personally, but saving time, travel & resource costs etc.
VR applications consume awesome levels of computing power. In contrast, AR applications are certainly not whatsoever demanding on resources - AR applications run comfortably on mobiles, tablets, other hand-helds, laptops and desktops. Very probably, you use a number of AR apps on the Android/ iOS device, right this moment, not understanding it! (e.g. Wordlens, Wikitude World Browser etc.).
The explanation for the real difference is the fact that VR apps first have to correctly interpret whatever action an individual performed and after that 'make out' the appropriate response the real environment would return, detailed with animation, movements within the right directions, sounds and so forth as well as, depending on correct physics, math as well as any other sciences involved. Most importantly, 'latency', or response time through the application, has to be sufficiently high. Or even, the consumer, who has include understandably high expectations, will certainly get so completely put-off that he/she might burst out with 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 necessary. Which explains, why.
