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 top level of resemblance with whatever will be depicted from real-life, either graphically or sensorially. The definition of 'sensorially' is broader than 'graphically' as it means all things perceptible to your senses I.e. graphics, touch, sound, voice, smell and so forth. Usually, the quality of resemblance with all the original must be often times higher plus much more accurate in the matter of VR compared to AR apps.

Consider the videos of an 100-metre dash from the recent Olympic Games. The original commentary could possibly be in English therefore, because it is, that video are not very welcome to the French. Either changing the commentary to French or adding suitable French sub-titles could make it more pleasurable with a French audience. This, in essence, is where AR finds its opportunity - augmenting the original with an increase of useful info - in your example, substituting French for English and consequently, making the information more valuable for the French-speaking. As the second example, take into account the video capture of an road accident. Two cars collide on a highway then one is badly damaged. Police officers might not be in a position to pin-point which present in drivers was accountable for the accident just by viewing the recording. If, however, it was pre-processed by an AR application that added mass, speed and direction info. with the cars to the video, then, usually the one responsible could possibly be established with close to, maybe, hundred-percent certainty.



VR (Virtual Reality), conversely, is quite not the same as AR. Actually, the two only share another thing alike - computer based simulation. As stated before, the simulation given by VR must be of these high quality that it is indistinguishable from reality. Theoretically, this can be impossible. Therefore, for practical purposes, VR only means a qualification 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 as with real-life e.g. within a VR application, imagine you're in a forest, getting ready to burn a pile of cut-down bushes and dry leaves. You douse the pile with gasoline. A fox is keenly watching you from an area place. Then you throw a lighted match-stick on to the pile... the device will respond immediately showing a powerful, quickly spreading fire burning around the pile, its shape occasionally altered through the blowing wind... and as in real-life... the fox (scared with the fire), must try to escape? - also it does! The machine may let you alter the direction, speed and alteration within the speed from the breeze, angle of throw of the match-stick etc. as well as the system will respond with all the new results immediately! Thus, VR enables one to try out real-life scenarios and have sufficiently accurate results equally as though he/she were in the desired environment/ place, personally, but saving time, travel & resource costs etc.

VR applications consume awesome quantities of computing power. When compared, AR applications usually are not at all demanding on resources - AR applications run comfortably on mobile phones, tablets, other hand-helds, laptops and desktops. Very probably, you're using a number of AR apps on your Android/ iOS device, right this moment, with no knowledge of it! (e.g. Wordlens, Wikitude World Browser etc.).

The real reason for the main difference is that VR apps first should correctly interpret whatever action the consumer performed and after that 'make out' the appropriate response that the real environment would return, full of animation, movements within the right directions, sounds etc as well as, depending on correct physics, math as well as any other sciences involved. Most importantly, 'latency', or even the response time from the application, needs to be sufficiently high. Otherwise, an individual, who may have come with 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 to the effect "to hell with this dumb thing!'. To avoid such failures, your personal computer (or network of computers) furnished with unusually powerful mobile processors, high-fidelity graphics software, precision motion trackers and advanced optics, is necessary. And that explains, why.
