Augmented reality
Augmented reality is a form of joining real mapping of the surrounding world with the media generated by a device on the screen of that device (usually mobile). It is device sensors (video camera, microphone, GPS, etc.) that play an important role in generating augmented reality allowing devices to register images of the surrounding world. The educational purpose of augmented reality is to provide instant support in understanding the reality surrounding the user and a mechanism for suggesting how a given task can be realized.
