Toward Characterizing the Productivity Benefits of Very Large Displays

Abstract: Larger display surfaces are becoming increasingly available due to multi-monitor capability built into many systems, in addition to the rapid decrease in their costs However, little is known about the performance benefits of using these larger surfaces compared to traditional single-monitor displays In addition, it is not clear that current software designs and interaction techniques have been properly tuned for these larger surfaces A preliminary user study was carried out to provide some initial evidence about the benefits of large versus small display surfaces for complex, multi-application office work Significant benefits were observed in the use of a prototype, larger display, in addition to significant positive user preference and satisfaction with its use over a small display In addition, design guidelines for enhancing user interaction across large display surfaces were identified User productivity could be significantly enhanced in future graphical user interface designs if developed with these findings in mind

System and method for analyzing system user behavior

Abstract: A system and method for monitoring and analyzing user activity of an interactive system, providing insight and recommendations to improve the interactive system based on the user activity. The present invention analyzes user behavior in the context of the structure of the interactive system as experienced by the user, the analysis of business-critical user tasks, the automated generation of recommendations for improving the interactive system, reports on the interactive system's application logic and data, unique visualizations of user behavior through the use of graphical displays, and secure report viewing and creation. The present invention can be applied to number of interactive systems or a combination thereof.

Display time as implicit feedback: understanding task effects

Abstract: Recent research has had some success using the length of time a user displays a document in their web browser as implicit feedback for document preference. However, most studies have been confined to specific search domains, such as news, and have not considered the effects of task on display time, and the potential impact of this relationship on the effectiveness of display time as implicit feedback. We describe the results of an intensive naturalistic study of the online information-seeking behaviors of seven subjects during a fourteen-week period. Throughout the study, subjects' online information-seeking activities were monitored with various pieces of logging and evaluation software. Subjects were asked to identify the tasks with which they were working, classify the documents that they viewed according to these tasks, and evaluate the usefulness of the documents. Results of a user-centered analysis demonstrate no general, direct relationship between display time and usefulness, and that display times differ significantly according to specific task, and according to specific user.

Selective information synchronization based on implicit user designation

Abstract: A device and method for synchronizing information between computer systems is provided. Certain subsets of information may be synchronized, while excluding other information from the synchronization process. The determination of the information subset to synchronize requires no explicit designation by the user. Instead, the subset of information to be synchronized is ascertained through actions of the user that implicitly indicate the user's interest in the information, allowing for an intuitive assumption of the user's synchronization desires, and requiring no user activity outside of the user's normal operational activity.

Empirical Evaluation of User Models and User-Adapted Systems

Abstract: Empirical evaluations are needed to determine which users are helped or hindered by user-adapted interaction in user modeling systems. A review of past UMUAI articles reveals insufficient empirical evaluations, but an encouraging upward trend. Rules of thumb for experimental design, useful tests for covariates, and common threats to experimental validity are presented. Reporting standards including effect size and power are proposed.
