Information Visualization, Human-Computer Interaction, Multimodal Interaction.
My research focuses on interactive information visualization. Specifically, I study visualization of time-based activity, including data such as video, sensor data, and annotations. My methods draw from those of cognitive psychology, cognitive ethnography, and computer science. As part of this research I have developed a number of software tools to explore visualization concepts and collect data about interacting with visualized data. This includes ChronoViz, a tool to support visualization of video, data, and associated annotations.
