Augmented Reality


Augmented Reality (AR) denotes techniques that show real world images or videos combined with additional visual information, must commonly with computer graphics.  In contrast to Virtual Reality the focus lies on the real world view, which is enriched by computer graphics which are not used to create an immersive artificial scenario.

Systems like the Heads-Up-Display (HUD) in modern cars show that AR is already part of our everyday life. Marking lines or spots in sport documentations are another famous example. Besides using annotations for the sake of information, AR is used in marketing and advertisment since the visual effect can boost the attractiveness of products.

Often the camera image suffices as tracking information.

Augmented Reality Software can be used on a wide variety of hardware, since it only requires the device to have a camera and a display. Therefore Smartphones are as well suited as AR device as most Laptops, Tablets and high end head worn devices as the SmartGlasses by Google, Vuzix, Epson, etc…
