oday, augmented reality (AR) is a fast growing technology, which connects the real world with the computer generated 3D world. To be more specific, it adds computer graphic elements over the real world environment in real time to give the user all kinds of information. For an AR technology to be fully qualified, the following three aspects must be fulfilled:
A. Combination of real world with the computer generated virtual world.
B. The results of combination of real world and virtual world should be interactive in real time.
C. The real time results should be presented to the user in 3D.
With the current technologies, all the above three aspects that qualify augmented reality are possible with the following equipment and devices:
1. Head gear with a transparent HUD (heads-up display).
2. Shader lamps, smart projectors, and mobile projectors that can spatially map out computer generated environment on any surface.
3. Handheld devices like smartphone equipped with camera, GPS, and MEMS (Microelectromechanical systems) sensors. (MEMS sensors basically controls accelerometer, digital compass, and gyroscope in a handheld device)
4.Eye gear or eye glasses with integrated HUD.
AR technology can be applied in various applications ranging from modern warfare to education, manufacturing and repairs to medical science, and much more. Let us look at some of the applications where AR assists the user by combining the real world with the computer generated imagery.
Military Aircraft
It has already been several years since military aircrafts and helicopters using headgear with HUD to overlay computer graphics upon the pilot's view of the real world. Apart from providing basic flight and navigation information, this augmented reality even registers the targets on the battlefield and provides the pilot a way to aim the aircraft weapons.
Manufacturing and Repairs
Augmented reality can even be applied in assembly, maintenance, and repair of complex machinery. AR can make the instruction easier by superimposing computer generated images on the actual equipment. This way, the technician will know the step-by-step task that need to be done and how to be done.
Medical Science
Doctors and surgeons can use AR technology as a visualization and training assistance for their patient's diagnosis and/or surgery. AR can make it possible to collect medical data of the patient in real time using non-invasive beams like computed tomography (CT) scans, magnetic resonance imaging (MRI), or ultrasound imaging. Furthermore, this medical data could be analyzed within the matter of seconds' right in front of the doctor's eyes, enabling quick remedy to the patient's ailment. Even while operating the patient, AR can assist the surgeon by providing step-by-step instruction, as well as constant monitor feed of patient's heartbeat, blood pressure and so on.
Aside from this, AR technology is also applied in archaeology, art, commerce, education, architect, sports, tourism, entertainment, workplace, and much more. AR technology is growing quickly and within few years from now, who knows where it will reach.
