Envelope of Human Cognition for Battlefield Information Processing

Das, S. Proceedings of the 10th International Conference on Information Fusion, Quebec City, Canada (July, 2007) In this paper, we describe Envelope, an adaptive, symbolic, and hybrid cognitive architecture. Envelope integrates reactive and skill-based human behavior, which relies primarily on working memory, with conscious and knowledge-based problem-solving behavior, which relies heavily on long-term memory. Envelope […]

Determining the Impact of Auditory Peripheral Displays for UAV Operators

Graham, H., Fouse, A., Cummings, M., & Pfautz, J. Proceedings of the Fourth Annual Workshop on Human Factors of Unmanned Aerial Vehicles, Chandler, AZ (May, 2007) Unmanned aerial vehicle (UAV) operators work in an information-rich environment. As a result, there is a desire to improve operator performance by utilizing alternate modalities of information display, primarily […]

Video Surveillance of Pedestrians and Vehicles

Gutchess, D., Ablavsky, V., Thangali, A., Sclaroff, S., and Snorrason, M. Proceedings of SPIE Defense & Security, vol. 6569, Orlando, FL (May, 2007). In this paper, we focus on the problem of automated surveillance in a parking lot scenario. We call our research system VANESSA, for Video Analysis for Nighttime Surveillance and Situational Awareness. VANESSA […]

Learning Patterns of Activity for Anomaly Detection

Gutchess, D., Checka, N., and Snorrason, M. Proceedings of SPIE Defense & Security, vol. 6560, Orlando, FL (May, 2007). Commercial security and surveillance systems offer advanced sensors, optics, and display capabilities, but lack intelligent processing. This necessitates human operators who must closely monitor video for situational awareness and threat assessment. For instance, urban environments are […]

Spatiotemporal Clustering from Noisy Data

Kanjilal, P., Das, S., and Lawless, D. IJCAI Workshop on Spatial and Temporal Reasoning, Hyderabad, India (January, 2007) Spatiotemporal clustering of multiple objects in a simulated space is considered. New preprocessing methods using Singular Value Decomposition (SVD) and Approximate Entropy are discussed to reduce clutter. A systematic procedure is presented to identify spatiotemporal clusters in […]

Formalizing Ecological Display Development: The Form Comparison Matrix

Kilgore, R. Proceedings of the 51st Annual Meeting of the Human Factors and Ergonomics Society, Baltimore, MD (October 2007). Combined, the Ecological Interface Design (EID) and Cognitive Work Analysis (CWA) frameworks foster the development of complex system interfaces that capitalize on human perceptive capabilities to support skill-, rule- and knowledge-based control behavior. While numerous examples […]

Modeling the Effects of Behavior Moderators for Simulation-Based Human-Factors Design

Neal Reilly, S., Bachman, J., Harper, K., Marotta, S., and Pfautz, J. Proceedings of the 51st Annual Meeting of the Human Factors and Ergonomics Society, Baltimore, MD (October, 2007) Designing systems, interfaces, procedures and artifacts in simulated environments before they are developed and deployed has the potential to greatly decrease the costs of design and […]
