AR (Augmented Reality) & Virtual Reality (VR) applications (apps) are according to computer simulation of real-life scenarios and environments. The simulation will bear a high degree of resemblance with whatever has been depicted from real-life, either graphically or sensorially. The phrase ’sensorially’ is broader than ’graphically’ since it means as much as possible perceptible to your senses I.e. graphics, touch, sound, voice, smell and so on. Usually, how much resemblance with all the original must be often times higher and more accurate in the case of VR when compared to AR apps.
Consider the videos of a 100-metre dash from the recent Olympics. The original commentary might be in English and if so, as it is, that video are not very thank you for visiting the French. Either changing the commentary to French or adding suitable French sub-titles can make it more fulfilling with a French audience. This, basically, is the place AR finds its opportunity – augmenting the first with additional useful info – in your example, substituting French for English and as a consequence, making the content more valuable towards the French-speaking. As the second example, consider the video capture of a road accident. Two cars collide on a highway and one is badly damaged. The police is probably not capable to pin-point which of these two drivers was responsible for the accident just by viewing it. If, however, it was pre-processed by an AR application that added mass, speed and direction info. with the cars towards the video, then, normally the one responsible could be established with near, maybe, hundred-percent certainty.
VR (Virtual Reality), however, is pretty distinctive from AR. Actually, the two only share something alike – computer based simulation. As pointed out above, the simulation supplied by VR needs to be of such top quality it is indistinguishable from reality. Theoretically, that is impossible. Therefore, for practical purposes, VR only means a college degree of approximation, sufficient for a user to get a ’live’ experience 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 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 against an area place. Then you definitely throw a lighted match-stick on to the pile… it will respond immediately showing a powerful, quickly spreading fire burning around the pile, its shape occasionally altered by the the wind… so when in real-life… the fox (scared with the fire), must hightail it? – plus it does! The machine may let you customize the direction, speed and alteration in the speed from the wind flow, angle of throw of the match-stick etc. and also the system will respond with the new results immediately! Thus, VR enables one to test out real-life scenarios and get sufficiently accurate results in the same way though he/she were inside the desired environment/ place, personally, but save your time, travel & resource costs etc.
VR applications consume awesome amounts 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 use a couple of AR apps in your Android/ iOS device, at this time, not understanding it! (e.g. Wordlens, Wikitude World Browser etc.).
The real reason for the gap is always that VR apps first should correctly interpret whatever action the user performed then ’make out’ the right response that this real environment would return, filled with animation, movements within the right directions, sounds and so on and also, according to correct physics, math and then for any other sciences involved. Most significantly, ’latency’, or the response time in the application, needs to be sufficiently high. Otherwise, an individual, who may have have 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 towards the effect "to hell with this 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 necessary. Understanding that explains, why.
