Augmented Reality is an interface technology that is changing the way we access information, Camera- equipped mobile phones with significant processing power and graphics abilities provide an inexpensive and versatile platform for AR applications, AR is a field where mobile camera vision and graphics meet and virtual and real objects appear together on the screen in real time. It has many possible applications in a wide variety of fields including marketing, entertainment, education, medicine and manufacturing.

Augmented reality (AR) is the integration of digital information with live video or the user's environment in real time. AR applications for smartphones include global positioning system (GPS) to pinpoint the user's location and its compass to detect device orientation. Basically, AR takes an existing picture and blends new information into it. AR applications require a camera program to deliver the information in the marker to the hand held device. The marker, which is sometimes called a target, might be a barcode or simple series of geometric shapes, like a picture. When the AR app receives the digital information contained in the marker, it begins to execute the code for the augmented reality program.
