Akers, David, Simpson, Matthew, Jeffries, Robin and Winograd, Terry (2009): Undo and erase events as indicators of usability problems. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 659-668. Available online

“One approach to reducing the costs of usability testing is to facilitate the automatic detection of critical incidents: serious breakdowns in interaction that stand out during software use. This research evaluates the use of undo and erase events as indicators of critical incidents in Google SketchUp (a 3D-modeling application), measuring an indicator's usefulness by the numbers and types of usability problems discovered. We compared problems identified using undo and erase events to problems identified using the user-reported critical incident technique [Hartson and Castillo 1998]. In a within-subjects experiment with 35 participants, undo and erase episodes together revealed over 90% of the problems rated as severe, several of which would not have been discovered by self-report alone. Moreover, problems found by all three methods were rated as significantly more severe than those identified by only a subset of methods. These results suggest that undo and erase events will serve as useful complements to user-reported critical incidents for low cost usability evaluation of creation-oriented applications like SketchUp.”

Riche, Yann, Simpson, Matthew and Viller, Stephen (2008): Zebra: exploring users' engagement in fieldwork. In: Proceedings of DIS08 Designing Interactive Systems 2008. pp. 50-57. Available online

“Participatory Design is a design approach that provides a popular set of techniques for designing interactive systems in collaboration with end-users. Technology probes are one of such techniques, developed recently to encourage users' engagement with design ideas while capturing interaction. In this paper, we describe a technology probe called Zebra, which aimed at exploring the design of an observation tool for fieldwork with busy professionals. We deployed Zebra in the coffee room of our lab and observed researchers' reactions to the proposed concepts it embodied, both as researchers and as participants. We found that participants engaged with the probe in ways ranging from playful performances, through to abandoning the social space. Based on analysis of the collected qualitative and quantitative data, we present our reflections on the Zebra probe, how it eased the burden of engagement in the design process, and helped us better understand the potential of the observation tool for participatory design with busy professionals.”
