AR (Augmented Reality) & Virtual Reality (VR) applications (apps) are both depending on computer simulation of real-life scenarios and environments. The simulation will bear a high degree of resemblance with whatever will be depicted from real-life, either graphically or sensorially. The term 'sensorially' is broader than 'graphically' since it means all things perceptible to the senses I.e. graphics, touch, sound, voice, smell and so forth. Usually, the degree of resemblance using 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 your 100-metre dash through the recent Olympic Games. The initial commentary might be in English therefore, as it's, that video will not be very here you are at in france they. Either changing the commentary to French or adding suitable French sub-titles will make it more fulfilling to a French audience. This, in simple terms, is when AR finds its opportunity - augmenting the first with additional useful info - within our example, substituting French for English and thus, making this article more significant towards the French-speaking. As another example, take into account the video capture of the road accident. Two cars collide on the highway and one is badly damaged. The police most likely are not able to pin-point which of the two drivers was responsible for the accident by merely viewing it. If, however, the recording 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 to, maybe, hundred-percent certainty.
VR (Virtual Reality), conversely, is fairly distinctive from AR. In fact, the 2 only share a very important factor in accordance - computer based simulation. As pointed out, the simulation supplied by VR needs to be for these top quality it is indistinguishable from reality. Theoretically, this is impossible. Therefore, for practical purposes, VR only means a degree of approximation, sufficient for the user to secure 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 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 an area place. Then you throw a lighted match-stick on to the pile... the system will respond immediately showing a powerful, quickly spreading fire burning about the pile, its shape occasionally altered by the wind flow... so that as in real-life... the fox (scared by the fire), must run away? - plus it does! The device may allow you to alter the direction, speed and alteration in the speed of the the wind, angle of throw from the match-stick etc. and also the system will respond with the new results immediately! Thus, VR enables one to experiment with real-life scenarios and get sufficiently accurate results just as though he/she were inside the desired environment/ place, face-to-face, but saving time, travel & resource costs etc.
VR applications consume awesome levels of computing power. When compared, AR applications usually are not whatsoever demanding on resources - AR applications run comfortably on mobiles, tablets, other hand-helds, laptops and desktops. Very probably, you're using a few AR apps on the Android/ iOS device, right now, with no knowledge of it! (e.g. Wordlens, Wikitude World Browser etc.).
The reason for the real difference is the fact that VR apps first must correctly interpret whatever action the consumer performed and then 'make out' the right response that this real environment would return, filled with animation, movements from the right directions, sounds and so on plus, as per correct physics, math as well as any other sciences involved. Most importantly, 'latency', or even the response time from your application, should be sufficiently high. If not, the person, that has come with understandably high expectations, will certainly get so completely put-off that he/she might burst by helping cover their a string of unprintable words to the effect "to hell using this type of dumb thing!'. In order to avoid 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 necessary. Which explains, why.
