AR (Augmented Reality) & Virtual Reality (VR) applications (apps) are based on computer simulation of real-life scenarios and environments. The simulation will bear an increased level of resemblance with whatever will be depicted from real-life, either graphically or sensorially. The word ‘sensorially’ is broader than ‘graphically’ given it means all things perceptible to our senses I.e. graphics, touch, sound, voice, smell and so forth. Usually, the quality of resemblance with all the original should be many times higher and much more accurate in the case of VR than in AR apps.
Take into account the video recording of the 100-metre dash in the recent Olympic Games. The original commentary might be in English and if so, since it is, that video are not very thanks for visiting french. Either changing the commentary to French or adding suitable French sub-titles is likely to make it more fun into a French audience. This, essentially, is when AR finds its opportunity – augmenting the initial with an increase of useful info – in your example, substituting French for English and consequently, making this content more vital towards the French-speaking. As another example, take into account the video capture of your road accident. Two cars collide over a highway and one is badly damaged. Law enforcement most likely are not able to pin-point which of the two drivers was in charge of the accident just by viewing the recording. 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, the main one responsible could possibly be established with close to, maybe, hundred-percent certainty.
VR (Virtual Reality), however, is fairly completely different from AR. The truth is, both only share one thing alike – computer based simulation. As pointed out above, the simulation supplied by VR must be for these quality that it must be indistinguishable from reality. Theoretically, that is impossible. Therefore, for practical purposes, VR only means a degree of approximation, sufficient to get a user to obtain a ‘live’ experience with the simulated environment. Moreover, VR is interactive and responds sensorially, in ‘real-time’, and simply as with real-life e.g. inside a 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 against a close place. Then you definitely throw a lighted match-stick onto the pile… it will respond immediately showing a powerful, quickly spreading fire burning about the pile, its shape occasionally altered from the breeze… so when in real-life… the fox (scared from the fire), must hightail it? – and it does! The machine may allow you to customize the direction, speed and alteration within the speed from the the wind, angle of throw in the match-stick etc. along with 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 as though he/she were inside the desired environment/ place, personally, but not waste time, travel & resource costs etc.
VR applications consume awesome numbers of computing power. In comparison, AR applications usually are not in any respect demanding on resources – AR applications run comfortably on mobile phones, tablets, other hand-helds, laptops and desktops. Very probably, you are using a few AR apps on your Android/ iOS device, today, lacking the knowledge of it! (e.g. Wordlens, Wikitude World Browser etc.).
The reason behind the main difference is that VR apps first must correctly interpret whatever action the consumer performed and then ‘make out’ the appropriate response that the real environment would return, detailed with animated graphics, movements from the right directions, sounds and the like as well as, depending on correct physics, math and then any other sciences involved. Most significantly, ‘latency’, or response time through the application, has to be sufficiently high. If not, the consumer, who may have feature understandably high expectations, will most likely get so completely put-off that he/she might burst out with a string of unprintable words to the effect "to hell with this dumb thing!’. To prevent 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 needed. Which explains, why.
