ABSTRACT
Ambiguity is usually considered anathema in Human Computer Interaction. We argue, in contrast, that it is a resource for design that can be used to encourage close personal engagement with systems. We illustrate this with examples from contemporary arts and design practice, and distinguish three broad classes of ambiguity according to where uncertainty is located in the interpretative relationship linking person and artefact. Ambiguity of information finds its source in the artefact itself, ambiguity of context in the sociocultural discourses that are used to interpret it, and ambiguity of relationship in the interpretative and evaluative stance of the individual. For each of these categories, we describe tactics for emphasising ambiguity that may help designers and other practitioners understand and craft its use.

Recommendations
Advancing ambiguity
CHI '06: Proceedings of the SIGCHI Conference on Human Factors in Computing SystemsAmbiguity is an important concept for HCI because of its pervasiveness in everyday life, yet its emergent nature challenges the role of design. We examine these difficulties with regards to Aoki and Woodruff's [1] proposal to use ambiguity as a resource ...
Ambiguity as a Resource to Inform Proto-Practices: The Case of Skin Conductance
Skin conductance is an interesting measure of arousal level, largely unfamiliar to most end-users. We designed a mobile application mirroring end-users’ skin conductance in evocative visualizations, purposefully made ambiguous to invite rich ...
Understanding interaction design practices
CHI '11: Proceedings of the SIGCHI Conference on Human Factors in Computing SystemsThere is an undesirable gap between HCI research aimed at influencing interaction design practice and the practitioners in question. To close this gap, we advocate a theoretical and methodological focus on the day-to-day, lived experience of designers. ...
