Enabling collaborative geoinformation access and decision-making through a natural, multimodal interface

Current computing systems do not support human work effectively. They restrict human-computer interaction to one mode at a time and are designed with an assumption that use will be by individuals (rather than groups), directing (rather than interacting with) the system. To support the ways in which humans work and interact, a new paradigm for computing is required that is multimodal, rather than unimodal, collaborative, rather than personal, and dialogue-enabled, rather than unidirectional. To address this challenge, we have developed an approach to natural, multimodal, multiuser dialogue-enabled interfaces to geographic information systems that make use of large-screen displays and integrated speech-gesture interaction. After outlining our goals and providing a brief overview of relevant literature, we introduce the Dialogue-Assisted Visual Environment for Geoinformation (DAVE_G). DAVE_G is being developed using a human-centered systems approach that contextualizes development and assessment in the current practice of potential users. In keeping with this human-centered approach, we outline a user task analysis and associated scenario development that implementation i
