AR (Augmented Reality) & Virtual Reality (VR) applications (apps) are both based on computer simulation of real-life scenarios and environments. The simulation will bear a higher a higher level resemblance with whatever has depicted from real-life, either graphically or sensorially. The word 'sensorially' is broader than 'graphically' as it means everything perceptible to the senses I.e. graphics, touch, sound, voice, smell and so forth. Usually, how much resemblance with the original has to be more often than not higher and more accurate when it comes to VR when compared to AR apps.

Take into account the videos of the 100-metre dash in the recent Olympic Games. The first commentary might be in English and if so, as it's, that video will not be very thank you for visiting french. Either changing the commentary to French or adding suitable French sub-titles is likely to make it more fulfilling to a French audience. This, basically, is the place AR finds its opportunity - augmenting the original with an increase of useful info - inside our example, substituting French for English and consequently, making this article more vital towards the French-speaking. As another example, take into account the video capture of a road accident. Two cars collide on a highway then one is badly damaged. The authorities most likely are not capable of pin-point which present in drivers was to blame for the accident by merely viewing the playback quality. If, however, it was pre-processed by an AR application that added mass, speed and direction info. in the cars to the video, then, normally the one responsible could be established with near, maybe, hundred-percent certainty.



VR (Virtual Reality), however, is quite completely different from AR. The truth is, the two only share a very important factor in keeping - computer based simulation. As pointed out, the simulation given by VR has to be for these quality it is indistinguishable from reality. Theoretically, this can be impossible. Therefore, for practical purposes, VR only means a degree of approximation, sufficient for any user to obtain a 'live' experience with the simulated environment. Moreover, VR is interactive and responds sensorially, in 'real-time', and merely as with real-life e.g. in the VR application, imagine you are in 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. Then you definitely throw a lighted match-stick onto the pile... the machine will respond immediately showing a strong, quickly spreading fire burning for the pile, its shape occasionally altered by the breeze... so when in real-life... the fox (scared from the fire), must back off? - and yes it does! The device may enable you to affect the direction, speed and alteration within the speed with the the wind, angle of throw in the match-stick etc. and the system will respond with the new results immediately! Thus, VR enables you to definitely research real-life scenarios and have sufficiently accurate results just as though he/she were from the desired environment/ place, personally, but save your time, travel & resource costs etc.

VR applications consume awesome amounts of computing power. In comparison, AR applications are not at all demanding on resources - AR applications run comfortably on cellphones, tablets, other hand-helds, laptops and desktops. Very probably, you're using a couple of AR apps on your own Android/ iOS device, right now, without knowing it! (e.g. Wordlens, Wikitude World Browser etc.).

The real reason for the main difference is the fact that VR apps first need to correctly interpret whatever action an individual performed and then 'make out' the proper response that the real environment would return, complete with animation, movements within the right directions, sounds and so on and also, depending on correct physics, math and then any other sciences involved. Most importantly, 'latency', or the response time from the application, has to be sufficiently high. If not, the consumer, who's 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 on the effect "to hell with this dumb thing!'. To stop such failures, a pc (or network of computers) equipped with unusually powerful mobile processors, high-fidelity graphics software, precision motion trackers and advanced optics, is needed. And that explains, why.
