Abstract:
The Human-Computer Interaction HCI Laboratory at the Naval Research Laboratory NRL is developing high-performance interactive computer systems for use in Naval command and control applications. New technology allows computerized systems to make greater use of a persons natural physical, perceptual, and cognitive skills. These systems make it faster and more straightforward for users to access and enter information within the context of time critical, real world situations. Our work focuses on developing novel interaction techniques-ways of using physical input and output devices to perform user tasks. Previous work has demonstrated the effectiveness of individual interaction techniques. This study is now being extended to encompass multi-modal interaction, in which combinations of interaction techniques am available to a user. We am incorporating these techniques into a command and control testbed, that will be tested through empirical, user-based evaluation. Such new capabilities increase the complexity of software development and maintenance requirements of already complex systems. New software architectures must co-evolve with the technology to structure and manage these additional requirements. This report describes the new demands placed on interactive systems and explains how we am addressing this challenge, through development of a flexible software architecture.
