    Complex interaction2010In: ACM Transactions on Computer-Human Interaction, ISSN 1073-0516, E-ISSN 1557-7325, Vol. 17, no 2Article in journal (Refereed)
    Abstract [en]

    An almost explosive growth of complexity puts pressure on people in their everyday doings. Digital artifacts and systems are at the core of this development. How should we handle complexity aspects when designing new interactive devices and systems? In this article we begin an analysis of interaction complexity. We portray different views of complexity; we explore not only negative aspects of complexity, but also positive, making a case for the existence of benign complexity. We argue that complex interaction is not necessarily bad, but designers need a deeper understanding of interaction complexity and need to treat it in a more intentional and thoughtful way. We examine interaction complexity as it relates to different loci of complexity: internal,external, and mediated complexity. Our purpose with these analytical exercises is to pave the way for design that is informed by a more focused and precise understanding of interaction complexity.

    The Anatomy of Prototypes: Prototypes as Filters, Prototypes as Manifestations of Design Ideas2008In: ACM Transactions on Computer-Human Interaction, ISSN 1073-0516, E-ISSN 1557-7325, Vol. 15, no 2, article id 7Article in journal (Refereed)
    Abstract [en]

    The role of prototypes is well established in the field of HCI and Design. A lack of knowledge, however, about the fundamental nature of prototypes still exists. Researchers have attempted to identify different types of prototypes, such as low-vs. high-fidelity prototypes, but these attempts have centered on evaluation rather than support of design exploration. There have also been efforts to provide new ways of thinking about the activity of using prototypes, such as experience prototyping and paper prototyping, but these efforts do not provide a discourse for understanding fundamental characteristics of prototypes. In this article, we propose an anatomy of prototypes as a framework for prototype conceptualization. We view prototypes not only in their role in evaluation but also in their generative role in enabling designers to reflect on their design activities in exploring a design space. We base this framework on the findings of two case studies that reveal two key dimensions: prototypes as filters and prototypes as manifestations. We explain why these two dimensions are important and how this conceptual framework can benefit our field by establishing more solid and systematic knowledge about prototypes and prototyping.

    Objects with Intent: Designing Everyday Things as Collaborative Partners2019In: ACM Transactions on Computer-Human Interaction, ISSN 1073-0516, E-ISSN 1557-7325, Vol. 26, no 4, p. 1-30, article id 26Article in journal (Refereed)
    Abstract [en]

    In HCI there is an increasing trend to approach computing artifacts as agents. In this article, we make a case for “Objects with Intent” (OwI’s) as an emerging type of agents that take advantage of the meaning of everyday things as the site for their intelligence and agency. After reviewing relevant existing research in HCI and related fields, we demonstrate how OwI’s provide a new perspective on human–agent interaction. We then elaborate on how the notion of OwI’s is informed by Dennett’s theory of intentionality and Leontiev’s Activity Theory. Thereafter, we illustrate the application of OwI’s through the design case of Fizzy, a robotic ball used to stimulate hospitalized children to engage in physical play. We end by discussing the nature and merit of OwI’s and reflecting more broadly on the challenges involved in designing OwI’s.
