Augmented Reality (AR) taps the potential of designing and presenting information where attention is fully paid: in the focus of visual and acoustic awareness. AR technology is part of a rapid development that aims at invisibly integrating computers into our everyday life. Using AR, physical surroundings are extended and, thus, augmented by the presentation of virtual elements. Research into virtual reality started 20 years ago, as did research into AR. Visualizations and simulations in medical science were to become the first fields of application of AR technology, followed by applications in military, car and aircraft industry. The use of AR in entertainment, tourism and computer games has become prominent only recently. Meanwhile, there are different approaches to adapting computer and video games and to staging objects of cultural value using AR technology.
