A conceptual update of affordance theory that introduces the mechanisms and conditions framework, providing a vocabulary and critical perspective. Technological affordances mediate between the features of a technology and the outcomes of engagement with that technology. The concept of affordances, which migrated from psychology to design with Donald Norman's influential 1988 book, The Design of Everyday Things, offers a useful analytical tool in technology studies—but, Jenny Davis argues in How Artifacts Afford, it is in need of a conceptual update. Davis provides just such an update, introducing the mechanisms and conditions framework, which offers both a vocabulary and necessary critical perspective for affordance analyses. The mechanisms and conditions framework shifts the question from what objects afford to how objects afford, for whom, and under what circumstances. Davis shows that through this framework, analyses can account for the power and politics of technological artifacts. She situates the framework within a critical approach that views technology as materialized action. She explains how request, demand, encourage, discourage, refuse, and allow are mechanisms of affordance, and shows how these mechanisms take shape through variable conditions—perception, dexterity, and cultural and institutional legitimacy. Putting the framework into action, Davis identifies existing methodological approaches that complement it, including critical technocultural discourse analysis (CTDA), app feature analysis, and adversarial design. In today's rapidly changing sociotechnical landscape, the stakes of affordance analyses are high. Davis's mechanisms and conditions framework offers a timely theoretical reboot, providing tools for the crucial tasks of both analysis and design.

Some 13,000 years ago, humans were drawn repeatedly to a small valley in what is now Central Texas, near the banks of Buttermilk Creek. These early hunter-gatherers camped, collected stone, and shaped it into a variety of tools they needed to hunt game, process food, and subsist in the Texas wilderness. Their toolkit included bifaces, blades, and deadly spear points. Where they worked, they left thousands of pieces of debris, which have allowed archaeologists to reconstruct their methods of tool production. Along with the faunal material that was also discarded in their prehistoric campsite, these stone, or lithic, artifacts afford a glimpse of human life at the end of the last ice age during an era referred to as Clovis. The area where these people roamed and camped, called the Gault site, is one of the most important Clovis sites in North America. A decade ago a team from Texas A&M University excavated a single area of the site—formally named Excavation Area 8, but informally dubbed the Lindsey Pit—which features the densest concentration of Clovis artifacts and the clearest stratigraphy at the Gault site. Some 67,000 lithic artifacts were recovered during fieldwork, along with 5,700 pieces of faunal material. In a thorough synthesis of the evidence from this prehistoric “workshop,” Michael R. Waters and his coauthors provide the technical data needed to interpret and compare this site with other sites from the same period, illuminating the story of Clovis people in the Buttermilk Creek Valley.

A foundational text offering a unified design vocabulary and a common methodology for maximizing the expressive power of digital artifacts. Digital artifacts from iPads to databases pervade our lives, and the design decisions that shape them affect how we think, act, communicate, and understand the world. But the pace of change has been so rapid that technical innovation is outstripping design. Interactors are often mystified and frustrated by their enticing but confusing new devices; meanwhile, product design teams struggle to articulate shared and enduring design goals. With Inventing the Medium, Janet Murray provides a unified vocabulary and a common methodology for the design of digital objects and environments. It will be an essential guide for both students and practitioners in this evolving field. Murray explains that innovative interaction designers should think of all objects made with bits—whether games or Web pages, robots or the latest killer apps—as belonging to a single new medium: the digital medium. Designers can speed the process of useful and lasting innovation by focusing on the collective cultural task of inventing this new medium. Exploring strategies for maximizing the expressive power of digital artifacts, Murray identifies and examines four representational affordances of digital environments that provide the core palette for designers across applications: computational procedures, user participation, navigable space, and encyclopedic capacity. Each chapter includes a set of Design Explorations—creative exercises for students and thought experiments for practitioners—that allow readers to apply the ideas in the chapter to particular design problems. Inventing the Medium also provides more than 200 illustrations of specific design strategies drawn from multiple genres and platforms and a glossary of design concepts.

'Useful Objects' examines the cultural history of nineteenth-century American museums through the eyes of writers, visitors, and collectors. Throughout this period, museums gradually transformed from encyclopedic cabinets to more specialized public institutions. These changes prompted wider debates about how museums determine what objects to select, preserve, and display-and who gets to decide. Drawing on a wide range of archival materials and accounts in fiction, guidebooks, and periodicals, this text shows how the challenges facing nineteenth-century museums continue to resonate in debates about their role in American culture today.

Whether he's attending a Bruce Springsteen concert the day after visiting Michael Brown's grave, or discussing public displays of affection at a Carly Rae Jepsen show, he writes with a poignancy and magnetism that resonates profoundly. In the wake of the nightclub attacks in Paris, he recalls how he sought refuge as a teenager in music, at shows, and wonders whether the next generation of young Muslims will not be afforded that opportunity now. While discussing the everyday threat to the lives of Black Americans, Abdurraqib recounts the first time he was ordered to the ground by police officers: for attempting to enter his own car. In essays that have been published by the New York Times, MTV, and Pitchfork, among others—along with original, previously unreleased essays—Abdurraqib uses music and culture as a lens through which to view our world, so that we might better understand ourselves, and in so doing proves himself a bellwether for our times.

In 1939, as the Nazis closed in, Alfred Berger mailed a desperate letter to an American stranger who happened to share his last name. He and his wife, Viennese Jews, had found escape routes for their daughters. But now their money, connections, and emotional energy were nearly exhausted. Alfred begged the American recipient of the letter, “You are surely informed about the situation of all Jews in Central Europe.... By pure chance I got your address.... My daughter and her husband will go... to America.... Help us to follow our children.... It is our last and only hope....” After languishing in a California attic for decades, Alfred’s letter ended up in the hands of Faris Cassell, a journalist who couldn’t rest until she discovered the ending of the story. Traveling across the United States as well as to Austria, the Czech Republic, Belarus, and Israel, she uncovered an extraordinary story of heart-wrenching loss and unforgettable love that endures to this day. Did the Bergers’ desperate letter find a response? Did they—and their daughters—survive? Did they leave living descendants? You will find the answers here. A story that will move any reader, The Unanswered Letter is a poignant reminder that love and hope never die.

To make sense of the world, we’re always trying to place things in context, whether our environment is physical, cultural, or something else altogether. Now that we live among digital, always-networked products, apps, and places, context is more complicated than ever—starting with "where" and "who" we are. This practical, insightful book provides a powerful toolset to help information architects, UX professionals, and web and app designers understand and solve the many challenges of contextual ambiguity in the products and services they create. You’ll discover not only how to design for a given context, but also how design participates in making context.
