Abstract. This paper raises the question of why electronic whiteboards are not ubiquitous. The paper provides a design-oriented analysis of traditional as well as electronic whiteboards in the context of collaborative and individual activities. We offer a novel perspective on whiteboards for collaborative activity based on a survey of the electronic whiteboard literature, a series of interviews with users of traditional whiteboards, and concepts rooted in Activity Theory. We identify a number of characteristics of the non-electronic whiteboard that are important to understand and preserve in the design of electronic whiteboard systems. Most importantly, we argue that the strength of non-electronic whiteboards is a combination of their simplicity and stability as well as a discontinuity between material on and outside of the whiteboard. We argue that the non-electronic whiteboard has uses and properties, which will require an electronic substitute to differ fundamentally in design compared to our traditional personal computing devices as well as most designs seen today. We present a set of themes for design of future electronic whiteboard systems that emphasize limitations as a main design principle. We conclude with three principles for design: The idea of installation rather than application; the principle of supplementing rather than replacing; and finally the principle of embracing and enhancing discontinuities.

“…Coupling capture and access capabilities to these surfaces would help document and share work with others. Commercially available systems such as SmartBoards, or research systems such as the ZombieBoard (which uses a camera and special glyphs to initiate capture; Saund, 1999), are examples of existing systems that could provide such services.…”

Computer Algebra Systems and matrix-based mathematics packages provide sophisticated functionality to assist with mathematical problem solving. However, despite their widespread adoption, little work in the human-computer interaction community has examined the extent to which these computational tools support expert problem solving. In this article, we report findings from a qualitative study comparing and contrasting the work practices and software use of practicing researchers in mathematics and engineering who share the goal of developing and defending new mathematical formulations. Our findings indicate that although computational tools are used by both groups to support their work, current mathematics software plays a relatively minor, somewhat untrusted role in the process. Our data suggest that five primary factors limit the applicability of current mathematics software to expert work practices: (a) a lack of transparency in how current software derives its computed results; (b) the lack of clearly defined operational boundaries indicating whether the system can meaningfully operate on the user's input (whether expressions or data); (c) the need for free-form two-dimensional input to support annotations, diagrams, and in-place manipulation of objects of interest; (d) the potential for transcription problems when switching between physical and computational Andrea Bunt is a computer scientist with an interest in cognitive tools, software complexity, and intelligent interactive systems; she is an Assistant Professor in the Department of Computer Science at the University of Manitoba.
