“…The need for a pointing device as an interaction item is underscored in [4], where a PDA is visually tracked to emulate a wand in an augmented reality environment. Multiview tracking of markers on the PDA provides pose information for augmenting the virtual wand, whereas this work employs a physical wand.…”

Abstract.A method is proposed that visually estimates the 3D pose and endpoints of a thin cylindrical physical object, such as a wand, a baton, or a stylus, that is manipulated by a user. The method utilizes multiple synchronous images of the object to cover wide spatial ranges, increase accuracy and deal with occlusions. Experiments demonstrate that the method can be applied in real-time using modest and conventional hardware and that the outcome suits the purposes of employing the approach for human computer interaction.

“…The Virtual Environments group at the Fraunhofer Society in Birlinghoven has developed several examples of the use of tracked PDAs ( (Simon et al, 2005), (Holtkämper et al, 2007)) and Tablet PCs (Holtkämper et al, 2007) in virtual environments. This approach has been mainly used for system control, but could also be used to show additional 2D information which would, due to the small displays, only be available to very few people.…”

3D stereoscopic visualization and virtual reality techniques are increasingly used for quality control, analysis and discussion of 3D geoscientific data in the oil and gas industry. They provide an excellent and easily comprehensible insight into complex 3D structures of the earth's subsurface. However, in many research topics in environmental and geosciences the analysis of data usually also involves data that might be better viewed in 2D. Examples are maps or histograms. The use of virtual environments as visual information systems for the efficient communication and discussion of complex multi-attribute data sets also requires 2D data to be visualized with a high quality. Further it is often not possible to show all the relevant information simultaneously and so an interactive virtual environment is required that provides an overview and the necessary interaction techniques to select additional information, e.g. from a database, to be visualized on request. This article describes the hardware setup installed at the UFZ Centre for Environmental Research and a software solution for how to use this setup efficiently to connect 2D data representations with 3D visualization and interaction.
