Augmented reality(AR) is a combination of perceived reality and computer-generated reality. Like augmented virtuality( AV), it belongs to mixed reality( MR). In contrast to virtual reality( VR), augmented reality involves providing the user with additional information that is directly related to real perceptions.
In augmented reality, reality is augmented by additional information, with real-time interaction between the perception and the additional information. In the first AR applications, real-time videos were enriched with computer graphics and animations. This AR technology was and is used in television for sporting events, where certain motion sequences are superimposed as moving lines on the live broadcast.
In this way, the running routes of soccer players can be made clear, or in other sports, the best marks to be beaten can be superimposed, for example in long jumping or ski jumping. The areas of application for augmented reality include almost all areas of daily life, including the service sector, where technicians are shown the individual service steps of the installation or repairs on a monitor.
Augmented reality and mobile communication
Newer developments rely on mobile communication and support users with additional information for location-based services( LBS), which is superimposed on the display of smartphones and iPhones. This additional information can be anything from geospatial and navigational data, information about historic buildings, properties for sale, exhibition exhibits, and much, much more. One example is the Layarapp for Android, which adds additional information to the real world. The programs are perfected in such a way that the user only has to hold the camera of his smartphone on a street, building or other object and additional information, graphics, animations or videos are displayed on the cell phone screen. For example, the route, the purchase price of a property, historical information about a building or a work of art. The display relies on image recognition, location, the viewer's current position and angle of view, and takes navigation data into account for possible directions.
Augmented reality can be used in humanitarian, disaster relief and entertainment applications. But it can also be used in construction work, in head-up displays in flight simulators or in automotive technology, building planning and exhibition technology.
