Sunday Morning, Half Day
Object-Oriented Design of Human-Computer Interaction
Convention Ctr — Room 15
Mary Beth Rosson, Virginia Tech

Object-oriented design methods are claimed to reduce the gap between the problem domain and the software system. This has important implications for the design of human-computer interaction: A software model that mirrors the real world should reduce the cognitive distance between how a system works and the mental models that users build to use and understand the software. This tutorial explores how to apply object-oriented thinking to the design of human-computer interaction. The methods discussed are part of a general scenario-based framework for usability engineering. In this framework, a scenario is a narrative of the goals, actions, and reactions of actors pursuing goals with an interactive system. The tutorial presents scenario-based techniques for developing and integrating object-oriented views of requirements, activity design, user interface design, and usability evaluation. Throughout, design rationale is captured, serving to raise and discuss the implications that object-oriented concepts will have for the user experience. Concepts and techniques are introduced briefly, then illustrated with examples. The format will be lecture interspersed with presentation and discussion of the examples.

Attendee Background: General knowledge of object-oriented concepts, interest in use-centered design of interactive systems.

Presenter: Mary Beth Rosson is an associate professor of computer science at Virginia Tech. She is an expert in human-computer interaction (HCI), and the author of numerous research papers on the relationship between HCI and object-oriented design. Rosson has given research papers and tutorials at the ACM SIGCHI, OOPSLA, and ECOOP conferences and has served in many leadership positions in SIGCHI and SIGPLAN. Most recently, she was General Chair of OOPSLA 2000.
