3D-interaction; input device comparison

The visualization domain handles complex data sets, which are visualized on a 2D screen. This is achieved by data transformations which cause a loss of information. Data can easier be analysed when interaction is supported. In the context of this paper multidimensional input devices refer to interaction devices with more than 2 degrees of freedom. I will consider a 6D-ball (the Spaceball from Spatial Systems) and a glove (the DataGlove from VPL, which incorporates a Polhemus 3Space Isotrack system). These are devices that support full 3D interaction. The paper is organized in two parts. The first part investigates the suitability of input devices for interaction in 3D scenes in general. A system is realized that supports the comparison of the "old" devices mouse and dials with the above mentioned "modern" devices. In particular the graphics interactions identifying and transforming an object (translation and rotation) are investigated and the results are presented. This system can als o be used to train users in getting familiar with the input devices. The second part of the paper describes the use of multidimensional input devices in scientific visualization applications, which are currently under research at FhG-IGD.(IGD)
