Toward Models of Information Re-Finding
Speaker: Rob Capra , Center for HCI, Virginia Tech
Date: November 21 2003
A considerable amount of research is conducted to help users find information on the web. However, re-finding information that has been found before is a considerably different process that has not been researched as extensively as finding. Computer users today often need to store, re-find, and re-use electronic information, yet these tasks are not well understood and have limited support in existing software tools and interfaces. Currently, there are no clearly established models of electronic information re-finding.
In this talk, I will present information re-finding from a human-computer interaction viewpoint, highlighting dimensions that could contribute to models of information re-finding. Our research group at Virginia Tech is exploring how people approach electronic information re-finding and how tools can support users' re-finding needs, especially across different computing platforms and devices. I will present results from empirical studies that illustrate the important role that artifacts such as waypoints play in the re-finding process. I will also present preliminary results from a controlled, laboratory study that is underway to investigate the effects that dimensions such as familiarity, frequency, and difficulty may have on the approaches that users take to re-find information.
Rob Capra is a Ph.D. student in HCI at Virginia Tech, graduating in the spring of 2004. His dissertation work focuses on information re-finding, especially for mobile users. He is a member of the CHI community and has published in the areas of HCI, AI, and Programming Languages. Rob's research interests include information management, voice user interfaces, and natural language processing. Prior to starting his Ph.D., he worked for five years in research and development for Southwestern Bell (SBC) in their Speech and Language Technology group, focusing on voice user interfaces for telephony applications. Rob has a Master's degree in computer science from Washington University in St. Louis and has over 20 years experience working with computers.
