Parnin, Chris and DeLine, Robert (2010): Evaluating cues for resuming interrupted programming tasks. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 93-102.

Developers, like all modern knowledge workers, are frequently interrupted and blocked in their tasks. In this paper we present a contextual inquiry into developers' current strategies for resuming interrupted tasks and investigate the effect of automated cues on improving task resumption. We surveyed 371 programmers on the nature of their tasks, interruptions, task suspension and resumption strategies and found that they rely heavily on note-taking across several types of media. We then ran a controlled lab study to compare the effects of two different automated cues to note taking when resuming interrupted programming tasks. The two cues differed in (1) whether activities were summarized in aggregate or presented chronologically and (2) whether activities were presented as program symbols or as code snippets. Both cues performed well: developers using either cue completed their tasks with twice the success rate as those using note-taking alone. Despite the similar performance of the cues, developers strongly preferred the cue that presents activities chronologically as code snippets.

Bach, Paula M., DeLine, Robert and Carroll, John M. (2009): Designers wanted: participation and the user experience in open source software development. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 985-994.

We present design concepts and related mockups that support the user experience for projects hosted on CodePlex, an open source project hosting website. Rationale for the design concepts is grounded in the open source literature and a thirteen-week study with the CodePlex team. We propose that fostering ways to build trust, providing opportunities for merit, supporting crossover of work activities, and supporting user experience (UX) best practices in CodePlex will help dismantle the social and technological barriers for UX and encourage UX designer participation. We address UX designer motivation as a challenge for participation and conclude that the mockups presented are a first step in furthering the user experience in open source software development.

DeLine, Robert (2008): development tools. In: Proceedings of the 2008 International Workshop on Cooperative and Human Aspects of Software Engineering 2008. pp. 33-36.

Developers need better knowledge tools to answer their information needs, rather than continuing to rely so heavily on communication with coworkers. Web sites, like the social bookmarking site, might provide a way forward. They are designed to provide each user an individual incentive for entering data, but provide even more value by combining data from different users into collective knowledge. Several research projects hint that designing knowledge tools for developers using this principle would be more cost effective and provide better incentive structures for capturing knowledge.

DeLine, Robert, Khella, Amir, Czerwinski, Mary and Robertson, George (2005): Towards understanding programs through wear-based filtering. In: Proceedings of the ACM Symposium on Software Visualization 2005. pp. 183-192.

Large software projects often require a programmer to make changes to unfamiliar source code. This paper presents the results of a formative observational study of seven professional programmers who use a conventional development environment to update an unfamiliar implementation of a commonly known video game. We describe several usability problems they experience, including keeping oriented in the program's source text, maintaining the number and layout of open text documents and relying heavily on textual search for navigation. To reduce the cost of transferring knowledge about the program among developers, we propose the idea of wear-based filtering, a combination of computational wear and social filtering. The development environment collects interaction information, as with computational wear, and uses that information to direct the attention of subsequent users, as with social filtering. We present sketches of new visualizations that use wear-based filtering and demonstrate the feasibility of our approach with data drawn from our study.

Mackinlay, Jock D., Robertson, George G. and DeLine, Robert (1994): Developing Calendar Visualizers for the Information Visualizer. In: Szekely, Pedro (ed.) Proceedings of the 7th annual ACM symposium on User interface software and technology November 02 - 04, 1994, Marina del Rey, California, United States. pp. 109-118.

The increasing mass of information confronting a business or an individual have created a demand for information management applications. Time-based information, in particular, is an important part of many information access tasks. This paper explores how to use 3D graphics and interactive animation to design and implement visualizers that improve access to large masses of time-based information. Two new visualizers have been developed for the Information Visualizer: 1) the Spiral Calendar was designed for rapid access to an individual's daily schedule, and 2) the Time Lattice was designed for analyzing the time relationships among the schedules of groups of people. The Spiral Calendar embodies a new 3D graphics technique for integrating detail and context by placing objects in a 3D spiral. It demonstrates that advanced graphics techniques can enhance routine office information tasks. The Time Lattice is formed by aligning a collection of 2D calendars. 2D translucent shadows provide views and interactive access to the resulting complex 3D object. The paper focuses on how these visualizations were developed. The Spiral Calendar, in particular, has gone through an entire cycle of development, including design, implementation, evaluation, revision and reuse. Our experience should prove useful to others developing user interfaces based on advanced graphics.

Pausch, Randy, Conway, Matthew and DeLine, Robert (1992): Lessons Learned from SUIT, the Simple User Interface Toolkit. In ACM Transactions on Information Systems, 10 (4) pp. 320-344.

In recent years, the computer science community has realized the advantages of GUIs (Graphical User Interfaces). Because high-quality GUIs are difficult to build, support tools such as UIMSs, UI Toolkits, and Interface Builders have been developed. Although these tools are powerful, they typically make two assumptions: first, that the programmer has some familiarity with the GUI model, and second, that he is willing to invest several weeks becoming proficient with the tool. These tools typically operate only on specific platforms, such as DOS, the Macintosh, or UNIX/X-windows. The existing tools are beyond the reach of most undergraduate computer science majors, or professional programmers who wish to quickly build GUIs without investing the time to become specialists in GUI design. For this class of users, we developed SUIT, the Simple User Interface Toolkit. SUIT is an attempt to distill the fundamental components of an interface builder and GUI toolkit, and to explain those concepts with the tool itself, all in a short period of time. We have measured that college juniors with no previous GUI programming experience can use SUIT productively after less than three hours. SUIT is a C subroutine library which provides an external control UIMS, an interactive layout editor, and a set of standard "widgets," such as sliders, buttons, and check boxes. SUIT-based applications run transparently across the Macintosh, DOS, and UNIX/X platforms. SUIT has been exported to hundreds of external sites on the internet. This paper describes SUIT's architecture, the design decisions we made during its development, and the lessons we learned from extensive observations of over 120 users.

Pausch, Randy, Young II, Nathaniel R. and DeLine, Robert (1991): SUIT: The Pascal of User Interface Toolkits. In: Rhyne, James R. (ed.) Proceedings of the 4th annual ACM symposium on User interface software and technology Hilton Head, South Carolina, United States, 1991, Hilton Head, South Carolina, United States. pp. 117-125.

User interface support software, such as UI toolkits, UIMSs, and interface builders, are currently too complex for undergraduates. Tools typically require a learning period of several weeks, which is impractical in a semester course. Most tools are also limited to a specific platform, usually either Macintosh, DOS, or UNIX/X. This is problematic for students who switch from DOS or Macintosh machines to UNIX machines as they move through the curriculum. The situation is similar to programming languages before the introduction of Pascal, which provided an easily ported, easily learned language for undergraduate instruction. SUIT (the Simple User Interface Toolkit), is a C subroutine library which provides an external control UIMS, an interactive layout editor, and a set of standard screen objects. SUIT applications run transparently across Macintosh, DOS, UNIX/X, and Silicon Graphics platforms. Through careful design and extensive user testing of the system and its documentation, we have been able to reduce learning time. We have formally measured that new users are productive with SUIT in less than three hours. SUIT currently has over one hundred students using it for undergraduate and graduate course work and for research projects.
