      1. Nebula The design of the garment evokes images of star fields and nebulas. Nebula is an interactive prototype used to examine the properties of textiles, fashion accessories, and digital technologies to arrive at a garment design that brings these elements together in a cohesive manner. Bridging the gap…

      What are you reading?

      The Sense of Style By Steven Pinker (2014) I love style guides and books about writing. As a nonnative speaker of English, I'm always on the lookout for a new resource to help me improve my language skills. Having read a few of Pinker's books and watched a couple…

      Remnance of form

      Describe what you made. Remnance of Form (typo intentional) is an interactive installation that explores the dynamic tension between an object and its shadow. The computer-generated shadow can transform into any shape, creating a new narrative that challenges our perception of reality. Our setup allows viewers to directly manipulate…

      I am a Luddite—-well, sort of

      Me, a Luddite? But I have not destroyed any machines. Not recently—or deliberately, anyway. On the contrary, I use plenty of machines and all sorts of digital online services. Moreover, I work on research and innovation projects that aim to create innovative ICT services. So, how am I a…

    • Why should we care about Bitcoin?

      Elizabeth Churchill

      Why should we care about Bitcoin?

      "Bitcoin Accepted," said the sign at the makeshift lemonade stand, staffed by a serious tween. "Really?" "Yes," she said. "Will cash do?" She shrugged as I handed her $2, two classic greenbacks. "It's changing the world," she said. "Bitcoin." I had not set out that morning thinking I would…

      Ending charge anxiety

      Who would think that electric vehicle charging stations—relatively simple technology compared with, say, facial recognition—could be so hard to use? It's not the interface on the device itself; that part is fairly simple. Tap a card, insert a plug, walk away. The problem lies in how the chargers are…

      How do you describe your lab to visitors? We design interactive products to solve the problems of developing countries. We believe that information and communication technologies (ICTs) give us the opportunity to address many problems that have plagued a large number of people in the world for many years.…

      Sustainability in an imaginary world

      What if our environmental crisis is as much a failure of our imagination as it is a moment of reckoning with the material consequences of modernity? What would technologically mediated public engagement with sustainability look like, if instead of discussing gallons of fuel or water consumed, carbon dioxide parts-per-million,…

      Isn’t it time to change the way we think about time?

      A number of publications have been concerned with the ways in which digital networks and systems may affect perceptions of time and everyday rhythms. Concerns are often directed to how new technologies may contribute to an overall speeding up of everyday life, and the negative consequences of this influence.…

      Exploring personal data for public good research

      Lifestyle and environment are important determinants of individual health and wellbeing. In the U.S., sedentary habits, poor diets, and a lack of sleep are widespread, contributing to the epidemics of obesity, diabetes, and cardiovascular disease. Exposure to environmental pollution is on the rise, linked with increased risk for asthma,…

      Design thinking and UX: Two sides of the same coin

      Over the past decade, design thinking has emerged as a boardroom buzzword promising innovation, quality, and the possibility of accelerating a progressive business agenda. At the same time, user experience (UX) has become a mission-critical consideration for companies in every industry, and of every shape and size. While many…

      Public policy and HCI

      All systems, whether human or technical, evolve and grow. And we often call the time frame for growth and development a lifecycle. The Interacting with Public Policy forum has had a lifecycle of six years. It is now time to allow new topics to grace the pages of Interactions.…

      Stefanie Mueller, Patrick Baudisch

      Laser cutters: A new class of 2D output devices

      The invention of new input and output devices has been a longtime enabler of human-computer interaction research. In particular, a combination of analog-digital and digital-analog converters allowed us to replace analog solutions with digital solutions. For instance, the invention of 2D scanners/printers allowed ordinary people to create printed products,…

      Online video and interactive TV experiences

      Media production and consumption are a central part of everyday life. People love to create, curate, and share media content using a variety of devices. It is no surprise, then, that leading device manufacturers, service providers, start-up innovators, and research groups are all vying to push the limits of…

    • Designing through value constellations

      Chris Speed, Deborah Maxwell

      Designing through value constellations

      Designers have always been good at mediating value. Their sensibilities for understanding how to manipulate materials, images, and actions have been adding value to products and services for a long time. Design studios across the world have used increasingly creative tactics to add value to both the most banal…

      Benefiting from legacy bias

      In "Reducing Legacy Bias in Gesture Elicitation Studies" (May–June 2014), Meredith Morris and colleagues presented a solution to the bias coming from users' "experience with prior interfaces and technologies, particularly the WIMP (windows, icons, menus, and pointing) interfaces that have been standard on traditional PCs for the past two…

      After interaction

      It is, arguably, where it all began for interaction. Doug Engelbart's retrospectively titled "The Mother of All Demos" spectacularly set the scene for what we do in HCI and especially for what we imagine interaction to be. Engelbart and his team showcased a remarkable collection of technologies for seeing…

    • Third-wave HCI, 10 years later—participation and sharing

      Susanne Bødker

      Almost 10 years ago I gave a keynote at NordiCHI in which I discussed the second and third waves of HCI [1]. I chose the topic due to a general frustration over whether the third wave was about to throw out the baby with the bath water, discarding what…
