AR (Augmented Reality) & Virtual Reality (VR) applications (apps) are generally according to computer simulation of real-life scenarios and environments. The simulation will bear a higher amount of resemblance with whatever will be depicted from real-life, either graphically or sensorially. The phrase ‘sensorially’ is broader than ‘graphically’ given it means things perceptible to our senses I.e. graphics, touch, sound, voice, smell and so forth. Usually, just how much resemblance together with the original must be more often than not higher plus much more accurate in the case of VR when compared to AR apps.
Look at the videos of a 100-metre dash through the recent Olympic Games. The main commentary may be in English and if so, as it is, that video will not be very welcome to france. Either changing the commentary to French or adding suitable French sub-titles could make it more fun into a French audience. This, in simple terms, is the place AR finds its opportunity – augmenting the first with additional useful info – in our example, substituting French for English and consequently, making this content more valuable to the French-speaking. As another example, think about the video capture of your road accident. Two cars collide over a highway and something is badly damaged. The police is probably not capable of pin-point which present in drivers was to blame for the accident by simply viewing the playback quality. If, however, it was pre-processed by an AR application that added mass, speed and direction info. with the cars to the video, then, the main one responsible could be established with near, maybe, hundred-percent certainty.
VR (Virtual Reality), alternatively, is quite distinctive from AR. In reality, both only share one thing in common – internet based simulation. As mentioned above, the simulation furnished by VR needs to be for these quality that it must be indistinguishable from reality. Theoretically, this really is impossible. Therefore, for practical purposes, VR only means a college degree of approximation, sufficient for the user to acquire a ‘live’ experience of the simulated environment. Moreover, VR is interactive and responds sensorially, in ‘real-time’, and such as real-life e.g. inside a VR application, imagine you’re in a forest, on the point of 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 throw a lighted match-stick on to the pile… the system will respond immediately showing a solid, quickly spreading fire burning around the pile, its shape occasionally altered from the breeze… and as in real-life… the fox (scared with the fire), must try to escape? – and yes it does! The machine may enable you to alter the direction, speed and alteration inside the speed with the breeze, angle of throw of the match-stick etc. and the system will respond together with the new results immediately! Thus, VR enables anyone to experiment with real-life scenarios and acquire sufficiently accurate results equally as though he/she were within the desired environment/ place, face-to-face, but time savings, travel & resource costs etc.
VR applications consume awesome quantities of computing power. In contrast, AR applications are certainly not at all demanding on resources – AR applications run comfortably on mobile phones, tablets, other hand-helds, laptops and desktops. Very probably, you are using a number of AR apps on your Android/ iOS device, today, without knowing it! (e.g. Wordlens, Wikitude World Browser etc.).
The real reason for the gap is VR apps first must correctly interpret whatever action the consumer performed and then ‘make out’ the appropriate response that the real environment would return, complete with animation, movements within the right directions, sounds and so on plus, as per correct physics, math and any other sciences involved. Most importantly, ‘latency’, or the response time through the application, must be sufficiently high. Otherwise, an individual, who may have come with understandably high expectations, is sure to get so completely put-off that he/she might burst out with a string of unprintable words for the effect "to hell with this dumb thing!’. To prevent such failures, some type of computer (or network of computers) equipped with unusually powerful mobile processors, high-fidelity graphics software, precision motion trackers and advanced optics, is necessary. And that explains, why.
