Augmented Reality (AR) is generally understood as the extension of images or image sequences through context-related meta-information. This can already be a simple display, for example, the name of the street in which you are located. But even complex applications, in which 3D models are projected, animated and rendered, are part of the state of art.
At the IOSB, the most modern technologies of man-machine interfaces are used. Bidirectional displays in spectacles, on the one hand, enable the pupil to be captured and thus the viewing direction; on the other hand, information can be directly displayed to the user.
The department VID is concerned, among other things, with the determination of the viewing direction in order to determine thereupon the object which the user is looking at. The objects and the information stored there are already predefined. In general, one differentiates between markerless and marker-based methods for object detection.
In the case of marker-free methods, methods of object recognition are used to locate and identify objects. Marker-based methods, on the other hand, use certain patterns, which are well known and easy to detect in shape and size. At the IOSB, so-called MCMXT badges have been specially developed for this purpose which permit reliable localization and identification (128 different badges), even with low image resolutions.
