TL;DR: The Timelines system is described, which was created to address both these paradigm shifts and two years of user testing results from the VANNA system, which supports both quantitative and qualitative analysis, and exploratory sequential data analysis.
Abstract: Human‐Computer Interaction (HCI) researchers collect, analyze, and interpret information about user behavior in order to make inferences about the systems they are designing. This paper describes four paradigm shifts in HCI research and discusses how each influences data collection and analysis. Based on these trends the implications for tool design are outlined. We then describe the Timelines system, which was created to address both these paradigm shifts and two years of user testing results from the VANNA system [4, 5, 6]. The Timelines system is an interactive data collection and visualization tool which supports both quantitative and qualitative analysis, and exploratory sequential data analysis. It accepts many diverse types of temporal data and provides the user with powerful data manipulation and color, graphical visualization tools. We summarize four representative case studies which reflect different methodological approaches and research goals, typical of our user community. From this the implications for the design of our system (and for data collection and analysis tools in general) are described.

TL;DR: This video presents the results of the studies into collaborative writing, and shows how the results have been applied to the design of SAS SE (Synchronous Asynchronous Structured Shared Editor).
Abstract: Writing k very often a collaborative activity. Despite this, very little is understood about how people write together, and very few systems are available to support this activity. This video presents the results of our studies into collaborative writing, and shows how the results of our work have been applied to the design of SAS SE (Synchronous Asynchronous Structured Shared Editor).

TL;DR: Timelines addresses the problem of coding the video and searching such temporal data for patterns in Generation of large sets of data using keystroke capture or video tape.
Abstract: The gathering and analysis of temporal data is an important and difficult step in evaluating interactive systems. Generation of large sets of data using keystroke capture or video tape is deceptively simple. The real difficulty lies in analysing this data. Timelines addresses this problem of coding the video and searching such temporal data for patterns.

TL;DR: MAD assists in the process of developing and refining the concept for a movie by supporting the intrinsically hierarchical nature of movies; it supports a top-down design approach as well as a bottom-up implementation approach.
Abstract: In this article we present a computer program called “MAD”, Movie Authoring and Design. Whereas most computer software for filmmaking focuses on the editing and post-production stage, MAD is designed specifically to support the authoring stage, and may be used before any film footage is shot. It assists in the process of developing and refining the concept for a movie by supporting the intrinsically hierarchical nature of movies; it supports a top-down design approach as well as a bottom-up implementation approach. MAD allows the user to keep script, storyboards, sounds, and digitized video clips together in a single document. Visualizing the final result is assisted by the “play” feature, which allows an approximation to the final film to be played on the author’s workstation at any time. The accuracy of this approximation increases as additional script, timing information, and other data is added to the movie.
