Augmented reality is a term for a live direct or indirect view of a physical real-world environment which is augmented by virtual computer-generated imagery. Lately there is a large lamber of augmented reality applications and platforms that work on mobile smartphones and tablets.
The applications are using a number of hardware components in order to produce the augmented reality environment. These include: screen, camera, GPS, compass, accelerometer, RFID reader etc. These are used together to identify the user’s location and field of view as well as understand its physical environment characteristics. From the collected data a number of calculations take place and geographical position, direction, screen picture and the other various forms of data are laid over the camera view, like inserting an additional layer of visual information over your screen picture.
The most well known platforms/applications are:
Wikitude was the world’s very first Augmented Reality Browser for smartphones in 2008. It was first published when Google introduced the first Android device end of 2008 (the G1), which (again) was the very first mobile device carrying the hardware components required to make AR possible: GPS, accelerometer and digital compass.
