Advanced Visualization Laboratory

Visualization is one of the most powerful tools that can be brought to bear as we expand the ways in which computing resources can be used to enhance human endeavors. Medical personnel make extensive use of visualization tools, signal processing and image reconstruction techniques as they render images of anatomical structures using scan data. Engineers rely on visualization tools as they design automobiles, bridges, and buildings. Visualization software is used to monitor the operating status of our air traffic, power grids, telephone networks, railroads and subway systems. This laboratory is an advanced visualization facility in which research in visualization, immersive virtual environments, and information fusion is conducted with a core theme of enhancing human and computer interaction and enabling information technology as an assistive partner in several human activities. Research conducted in this laboratory targets two broad areas of current interest: rehabilitation engineering and homeland security.

Problems inherent in the application of immersive virtual reality environments as an assistive technology for patient rehabilitation are investigated. This involves studying the interplay of visualization and immersion with real time physically accurate simulations with the goal of developing virtual environments that are both visually and physically realistic. New paradigms can be created for rehabilitation and advanced level training through a combination of immersion in 3-D realistic scenarios and knowledge based tutoring.

Many issues that are critical in homeland security require the development of new strategies to enhance human understanding of large, multi-source data sets and the operation of complex systems. By combining data fusion algorithms with visualization techniques and user interaction, we can build an environment in which people monitoring our critical infrastructure can be more effective. We can also enhance human collaborative abilities by tele-immersion and software agent-based decision-support methods.
