Abstract

The objectoriented visualization Toolkit VTK is widely used for scientific visualization VTK is a visualization library that provides a large number of functions for presenting threedimensional data Interaction with the visualized data is controlled with twodimensional input devices such as mouse and keyboard Support for real threedimensional and multimodal input is nonexistent This paper describes VRVTK a multimodal interface to VTK on a virtual environment Six degree of freedom input devices are used for spatial 3D interaction They control the 3D widgets that are used to interact with the visualized data Head tracking is used for camera control Pedals are used for clutching Speech input is used for application commands and system control To address several problems specific for spatial 3D interaction a number of additional features such as more complex interaction methods and enhanced depth perception are discussed Furthermore the need for multimodal input to support interaction with the visualization is shown Two existing VTK applications are ported using VRVTK to run in a desktop virtual reality system Informal user experiences are presentedArjan J F Kok is an assistant professor at the Department of Computer Science at the Open University of the Netherlands He studied Computer Science at the Delft University of Technology The Netherlands He received his PhD from the same university He worked as a Scientist for TNO Netherlands Organization for Applied Scientific Research and as assistant professor at the Eindhoven University of Technology before he joined the Open University His research interests are visualization virtual reality and computer graphicsRobert van Liere studied Computer Science at the Delft University of Technology the Netherlands He received his PhD with the thesis “Studies in Interactive Scientific Visualization” at the University of Amsterdam Since 1985 he has worked at CWI the Center for Mathematics and Computer Science in Amsterdam in which he is the head of CWI’s visualization research group Since 2004 he holds a parttime position as full professor at the Eindhoven University of Technology His research interests are in interactive data visualization and virtual reality He is a member of IEEEThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
