      TK 730 The TK 730 is a hybrid typewriter/knitting machine that converts words into a knitted code. It does this by decoding the typed word and re-encoding it into the pattern of the knitwork. The idea comes from the common root of the words text and textile: the Latin texere,…

      How I learned to stop worrying and love the deliverable

      I don’t remember when I first heard the word deliverable, but I do remember ferociously loathing it. Many of interactions’ readers undoubtedly live and breathe deliverables, but here’s a quick definition for those who are still innocent: A deliverable is a document created by one group of people that is…

      SIGCHI in Latin America

      After years of volunteer investment, SIGCHI is now at the center of the HCI network in North America, Europe, and the Pacific Rim. South of the border, however, is a different story. We meet occasionally with some of our Latin American colleagues at our conferences—typically only about 25 when CHI…

      From data divination to data-aware design

      In the past few years, I have sifted through more trace data than I care to remember. By trace data I mean logs of actions taken by users on Internet sites—mostly aggregated data from many users, but sometimes data from single users, such as search query logs. Why all this…

      The digital apprentice

      Imagine making fresh pasta in your kitchen. The ingredients get placed on the counter, one by one. Pour a cup of flour onto a board. Knead in the eggs, salt, and water. Roll out the dough; monitor its thickness. Cut, stuff, pinch, and boil. Now imagine what this might be…

      How do you describe your lab to visitors? The Game Innovation Lab is an interdisciplinary research and teaching space where we take games as an innovation challenge for advancing computer science and engineering as well as design. We designed the space to be highly reconfigurable, with affordances for creativity and…

    • Sustainability does not begin with the individual

      Sustainability does not begin with the individual

      In the past decade, an increasing amount of HCI research has been concerned with making personal and household environmental impacts (such as energy, water, or CO2 equivalents) more visible, with the aim of educating people and affecting their relevant actions. We have two concerns with this. First, when evaluated “in…

      Of turf fires, fine linen, and Porter cake

      Living history museums are challenging environments to enhance with interactive technology. Their heritage is complex, usually including entire buildings, historical artifacts, and live performances, all within an outdoor site often landscaped to be part of the display. Visitors explore living history museums with an interest in immersive reconstructions of ways…

      Will content credibility problems flatline health innovation?

      Digital content—the text, images, audio, and video that make up digital experiences—is in demand. And in few areas is it more in demand than health: Eight in 10 American Internet users have looked online for health information [1]. If you think about it, much health innovation explores how to get…

      Understanding HCI policy in Spain in the context of accessibility

      Spain pioneered policies related to disability and accessibility, especially in the physical environment. The first major piece of legislation was Act 13/1982 on the Social Integration of People with Disabilities [1]. The law was published just a few years after the reinstitution of democracy in Spain in 1977 and the…

      Punctuated equilibrium and technology change

      Several Timelines columns have argued that we fail to notice indirect consequences of successive waves of new hardware. This essay explores the dynamics of technology change, illustrated by an oscillation in the conditions affecting collaboration across continents in the computer-supported cooperative work community. Major technology shifts affect technology producers and…

      Coherence and responsiveness

      The world we live in is full of systems: phone systems, legal systems, air traffic control systems, educational systems, banking systems, digital communication systems (such as the Internet), computer operating systems, purchasing systems, HR systems, healthcare systems. Systems are designed and evolved; they are built, maintained, modified, and replaced. Systems…

      Tech break ups

      I’m sorry to say, skinny Moleskines, but I’m breaking up with you. Have you ever broken up with someone? I’ll bet it was painful. Hidden secrets come pouring out; hurtful words are exchanged. And yet, for the first time in a long time, it feels good to be totally, brutally…

      Understanding unavailability in a world of constant connection

      Historically, the problem of coordinating opportunities for real-time communication has been dominated by the problem of co-presence. Before there was any interactive media, people had to be in the same place to talk. Visiting somebody’s house (“calling,” in the early sense) to see if they were available or scheduling a…

      Disappearing interfaces

      One day I was watching a TV commercial for Apple’s iPad2. The script definitely had an Apple ring to it. The ad began with, “Now we can watch a newspaper,” and ended with, “and touch the stars!” This upset me at first, because it seemed to overstate what the product…

      The design case

      When designers work, no matter what process they follow or type of thinking they employ, they inevitably face the moment of invention. This is the point at which no theory, guideline, example, or statement of best practice can tell the designer or the design team specifically what to do [1].…

      Modeling is not the answer!

      In a 2008 CACM Viewpoints column, Susan Landau [1] calls for an understanding of the complexity of human behavior underlying IT security and proposes a multidimensional approach, with contributions from areas such as business, anthropology, and engineering. The reason for including these various fields is that the strong cryptology and…

      HCI for peace

      Two hundred thirty-seven million. That is a conservative estimate of the number of people killed as a direct consequence of war and doctrinal hatred during the 20th century [1]. It’s the equivalent of two 9/11 attacks every day for the entire century. One trillion two hundred eighty-three billion dollars. That…
