Abstract:
Cognitive science is beginning to provide us with well-supported models of the stages that professional analysts go through in the course of conducting an investigation, be it reactive or proactive in nature. These models generally fall under the title of Sensemaking, with one of the most well-known models being that of Pirolli and Card.
In using these models to improve visual analytics systems, we have at least two distinct problems: (1) how to infer high-level knowledge of the Sensemaking states from a record of user interactions with an interactive analysis system, and (2) how to use this knowledge to provide user guidance resulting in better human-machine interaction and a more robust investigative process. The answers to these questions lie at the intersection of research in machine learning, knowledge representation, user interfaces and cognitive science, and addressing them requires an end-to-end system perspective.
In this talk, we discuss our initial approach to these problems and the insights gained into building interactive systems that support users' cognitive models.
