The simplest definition of Augmented Reality (AR) is that it's a field of computer science that involves combining the physical world and an interactive, 3D virtual world.
Augmented reality (AR) is a live, direct or indirect, view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data.
Applications of Augmented Reality -
1] Interactive real time processing:
2] Video Games :
The video game industry has released major augmented
reality products for more than a decade. The EyeToy for Sony PlayStation 2 and
3 takes input from an inexpensive video camera and composites the live video feed with CG onto the TV screen. This toy detects the user's body position in
front of the camera as an alternative input method to the typical joystick or
gamepad.
3] Physical interactions with 3D models :
4] Simulations:
