The working group "Multimedia
NRW: The Virtual Knowledge Factory", founded in 1996, is a collaborative
effort to bundle research from different areas of human-machine interaction.
The SGIM project contributes to this overall goal by developing techniques
for communicating with multimedia systems through the detection and interpretation
of a user's verbal (speech) and coarse gestural input. The aim is to overcome
the physical limitations of common computer displays and input devices;
to enable enhanced interaction methods when using large-screen displays
(wall projections, workbenches, caves), thus allowing the user to operate
an application system in a more natural and convenient manner.
In
an experimental
application of virtual construction 'users' gestural communication
is supported by simple speech input. Object types and locations can be
referenced via verbal expressions, e.g. "...this wheel", to identify objects
and locations in sole cases where gestural communication is unnatural or
reaches technical limitations. Therefore, the gestural data gathered by
electromagnetic 6DOF position- and orientation sensors
(trackers) s integrated with output from a speech analyser to form
multimodal inputs for the multimedia system.
The
construction of a mobile platform ("City-Mobile"), based on large-screen
projected CAD-models, serves as a shared testbed application which integrates
the results achieved by the different research groups. M4I
"Multi modal Man Machine Interaction" from the University of Bielefeld,
the Institute for Media
Communication in St. Augustin and the European Centre for Mechatronic
in Aachen concentrate their efforts on the implementation of a demonstration
system to evaluate the research results using a real world application.
Project cooperation exists with several other institutions. The Graduate
Study Program `Task-oriented Communications' as well as the Collaborative
Research Center 'Situated Artificial Communicators' (SFB360) of the University
of Bielefeld are in-house partners in the project.
The research project SGIM is embedded in the working group "Multimedia NRW - The Virtual Knowledge Factory" and is sponsored by the Ministry of Science and Research of the Federal State North-Rhine-Westphalia under grant no. IV A 3 - 107 032 96.
