Research areas in the Displays Federated Laboratory with participating UIUC faculty. Database Management for Battlefield Visualization and Planning Drs. Sharad Mehrotra, Douglas Johnston, Caroline Hayes, and Ouri Wolfson Objective: To develop and validate techniques for improving user performance in the management and interaction with multidimensional (spatio-temporal) databases used for battlefield information. View Papers in This Area Intelligent Information Processing for Visualization Drs. Caroline Hayes, Gerald DeJong, David Wilkins, Patricia Jones, Janet Sniezek, Robin Bargar, and David Goldberg Objective: To develop intelligent information processing techniques for the filtering, fusion, and selection of time-critical spatial/temporal battlefield information for display in a soldier’s or commander’s multimedia display system. Also, to develop methods to model and track the user’s changing tasks, goals, and priorities, and use them to control information collection and display. View Papers in This Area  Visual Representation and Virtual Space Displays Drs. M. Pauline Baker, Christopher Wickens, William Sherman, and Douglas Johnston Objective: To develop and empirically validate effective techniques for presentation and interaction with terrain and battle-related information on desktop and virtual reality displays. View Papers in This Area Computer Vision-Based Augmented Reality Drs. Christopher Wickens, and Narendra Ahuja Objective: To enhance situational awareness using AR technology. Improve techniques to align real and virtual objects, and study the cognitive issues and perform analysis for guided augmentation for AR. View Papers in This Area Visual Perception and Eyetracking in Virtual Reality Environments Drs. George McConkie, Arthur Kramer, and David Zola Objective: To study issues in visual perception and eye movement control that arise in virtual reality situations. These studies will yield information to guide the development of displays for virtual reality environments, and for using eye gaze as a control device. View Papers in This Area 3D Audio and Information Integration Drs. Robin Bargar, Yunxin Zhao, and Ken Wang Objective: To prototype components of an individualized, user-sensitive auditory display that enhances a listener’s ability to understand multiple messages to increase situational awareness in a minimized time span. View Papers in This Area Tactile Interface Dr. David Beebe Objective: To develop novel tactile interface schemes for display and display control. View Papers in This Area Speech and Vision Integration for Display Control Drs. Thomas Huang, Rajeev Sharma, Jerry Morgan, Yunxin Zhao, and Jim Bass Objective: To develop novel and effective paradigms for human computer interface combining vision, speech, and natural language understanding. View Papers in This Area Physiological Indicators of Cognitive/Attentional States Drs. Arthur Kramer, George McConkie, Celestine Ntuen Objective: To investigate the utility of physiological indices as real-time measures of attention, mental workload, and the functional state (i.e., level of alertness) of the soldier. View Papers in This Area Cognitive Modeling of Virtual Reality Environments Drs. George McConkie, Arthur Kramer, Christopher Wickens, and David Zola Objective: To investigate the development and use of cognitive representations of virtual space, and factors that affect these representations. View Papers in This Area Image/Video Compression for Display Environments Drs. Thomas Huang, and Kannan Ramchandran Objective: To develop image/video compression and representation techniques that are suitable for distributed databases and multiple display resolutions. Key performance criteria are scalability, interoperability, and ease of manipulation View Papers in This Area Integrated Systems Laboratory Ms. Rachael Brady Objective: View Papers in This Area
