Item The Design of History Mechanisms and Their Use in Collaborative Educational Simulations(1999) Plaisant, C.; Rose, A.; Rubloff, G.; Salter, R.; Shneiderman, B.; ISRReviewing past events has been useful in many domains. Videotapes and flight data recorders provide invaluable technological help to sports coaches or aviation engineers. Similarly, providing learners with a readable recording of their actions may help them monitor their behavior, reflect on their progress, and experiment with revisions of their experiences. It may also facilitate active collaboration among dispersed learning communities. Learning histories can help students and professionals make more effective use of digital library searching, word processing tasks, computer-assisted design tools, electronic performance support systems, and web navigation.This paper describes the design space and discusses the challenges of implementing learning histories. It presents guidelines for creating effective implementations, and the design tradeoffs between sparse and dense history records. The paper also presents a first implementation of learning histories for a simulation-based engineering learning environment called SimPLE (Simulated Processes in a Learning Environment) for the case of a semiconductor fabrication module, and reports on early user evaluation of learning histories implemented within SimPLE.
Item LifeLines: Visualizing Personal Histories(1995) Plaisant, C.; Milash, Brett; Rose, A.; Widoff, S.; Shneiderman, B.; ISRLifeLines provide a general visualization environment for personal histories that can be applied to medical and court records, professional histories and other types of biographical data. A one-screen overview shows multiple facets of the records. Aspects, for example medical conditions or legal cases, are displayed as individual time lines, while icons indicate discrete events, such as physician consultations or legal reviews. Line color and thickness illustrate relationships or significance, scaling tools and filters allow users to focus on part of the information. LifeLines reduce the chances of missing information, facilitate spotting anomalies and trends and streamline access to details, while remaining tailorable and easily sharable between applications. The paper describes the use of LifeLines for youth records of the Maryland Department of Juvenile Justice and also for medical records. User's feedback was collected using a Visual Basic Prototype for the youth record. Techniques to deal with complex records are reviewed and issues of a standard personal record format are discussed.Item A Photo History of SIGCHI: Evolution of Design from Personal to Public(2002-09-18) Shneiderman, B.; Kules, B.; Plaisant, C.; Rose, A.; Rucheir, R.For 20 years I have been photographing personalities and events in the emerging discipline of human- computer interaction. Until now, only a few of these photos were published in newsletters or were shown to visitors who sought them out. Now this photo history is going from a personal record to a public archive. This archive should be interesting for professional members of this community who want to reminisce, as well as for historians and journalists who want to understand what happened. Students and Web surfers may also want to look at the people who created better interfaces and more satisfying user experiences. (Also UMIACS-TR-2002-77) (Also HCI-TR-2002-14)
