  • Welcome
    • WELCOMEParticipation, technology and interaction design

      Ron Wakkary, Erik Stolterman

      As a reader of this magazine, you are probably involved in some new forms of social participatory work made possible by the Internet and interactive technology. Many of us are working to achieve some common goal by using technology that helps us conquer distance and time. It seems as if…

    • Killing off user-centered design

      John Zimmerman

      Over the past few years, I have heard many proclamations and complaints from IxD/HCI practitioners and researchers that make me feel we have lost our way, that we have drunk a bit too much of our own Kool-Aid. I am the user’s advocate. I fight with the developers and managers…

    • BETWEEN THE LINES The social life of marginalia

      Liz Danzico

      On a single day, I count 44 notes I’ve scribbled down while traveling between home and work. These notes are part private, part public, and all parts messy. These are everyday marginalia—notes in a printed book, saves in Instapaper, lists in Simplenote, snaps in Instagram, likes in Tumblr, shares in…

    • Making time

      Elizabeth Churchill

      “One morning, as Gregor Samsa was waking up from anxious dreams, he discovered that in his bed he had been transformed into a monstrous verminous bug.” Thus begins one of my favorite novels, The Metamorphosis, by Franz Kafka. What is most remarkable about Gregor’s awakening, in which he discovers that…

    • Building outwards from sustainable HCI

      Elaine Huang

      This column marks the start of a new forum for interactions entitled Sustainability in (Inter)Action, which considers the application of HCI and interaction design to problems of environmental sustainability and explores the ways in which knowledge and expertise from other fields can contribute to these efforts. In recent years there…

    • An internet of things that do not exist

      Chris Speed

      What are the implications of our relationship with physical artifacts as the technical and cultural phenomenon known as the Internet of Things begins to emerge? The term, coined in 1999, is attributed to the Auto-ID research group at MIT and was explored in depth by the International Telecommunication Union in…

    • IT in healthcare

      Elizabeth Mynatt

      Healthcare is both deeply personal and staggeringly complex. It starts with individual physical bodies and stretches to include an array of technologies, physical places, caregiver networks (both formal and informal), and decision-making tasks. Each configuration of body, people, technology, places, and decisions presents compelling and timely challenges for human-centered computing.…

    • INTERACTING WITH PUBLIC POLICYAre HCI researchers an endangered species in Brazil?

      Simone Barbosa, Clarisse de Souza

      Recently, Brazilian researchers have been receiving mixed signals regarding the recognition of human-computer interaction (HCI) as a relevant area of study in Brazil. On the one hand, HCI was granted considerable prestige when the Brazilian Computer Society launched its Five Grand Challenges for the decade in 2006. One of them…

    • TIMELINESThe DigiBarn computer museum

      Bruce Damer

      In 1993 ACM sponsored HCI researchers on a vist to Eastern and Central Europe. I met Bruce Damer in Prague, where he held a professorship in computer science despite not having a Ph.D. Bruce quickly impressed me as one of the most brilliantly creative people I’d ever met, a visionary…

    • Conversational alignment

      Austin Henderson, Jed Harris

      People invent and revise their conversation midsentence. People assume they understand enough to converse and then simply jump in; all the while they monitor and correct when things appear to go astray from the purposes at hand. This article explores how this adaptive regime works, and how it meshes with…

      Jeanine* was a 32-year-old project manager, married and pregnant with her first child. She regularly posted Facebook updates about her pregnancy to share her excitement with friends and family, often with accompanying cell phone photos of her growing belly. After nine months of anticipation and a smooth delivery, she gave…

      Pedro Campos, Miguel Campos, Joaquim Jorge

      The experience is common: You and your interaction design teammates have collaboratively conceived, designed, and installed a fancy multimedia installation, following every important user-centered design principle, actively involving all stakeholders in the design process, validating every requirement and concern, and finally installing the myriad of equipments needed. And you did…

    • Public policy and HCI in the U.S. context

      Jonathan Lazar

      Although most of us working in HCI have no background in public policy, non-governmental and governmental policy decisions have a major impact on the work that we do. This is true across the globe. As researchers we are used to collaborating internationally; therefore, I know not everyone within the research…

    • How prototyping practices affect design results

      Steven Dow

      Iterate rapidly. Explore broadly. Gather feedback from multiple sources. Don’t conflate ego with object. These pearls of wisdom state principles and values with which few designers disagree. Behind these mantras lie decades of human science research that can enrich our understanding of design. For the past few years, my Stanford…

    • Using 3-D projection to bring a statue to life

      Kim Halskov, Peter Dalsgaard

      In the dungeons of Kronborg, a nearly 400-year-old Renaissance castle known from Shakespeare’s Hamlet, there is a statue of Holger the Dane. Holger the Dane is a mythical figure who, according to one myth, will awaken and defend the country when an enemy from beyond the borders threatens the kingdom…

      Jeremiah Still

      Like many who submit manuscripts to the CHI conference each year, I look forward to reading the reviewers’ reflections on my submissions. This year my coauthors and I were asked to justify the validity of our highly controlled research; similar requests have been made of our recent submissions to journals.…

    • Understanding, fostering, and supporting cultures of participation

      Gerhard Fischer

      Cultures are defined in part by their media and their tools for thinking, working, learning, and collaborating. In the past, the design of most media emphasized a clear distinction between producers and consumers [1]. Television is the medium that most obviously exhibits this orientation and has contributed to the degeneration…
