The LilyPad Arduino: using computational textiles to investigate engagement, aesthetics, and diversity in computer science education

Abstract: The advent of novel materials (such as conductive fibers) combined with accessible embedded computing platforms have made it possible to re-imagine the landscapes of fabric and electronic crafts--extending these landscapes with the creative range of electronic/computational textiles or e-textiles. This paper describes the LilyPad Arduino, a fabric-based construction kit that enables novices to design and build their own soft wearables and other textile artifacts. The kit consists of a microcontroller and an assortment of sensors and actuators in stitch-able packages; these elements can be sewn to cloth substrates and each other with conductive thread to build e-textiles. This paper will introduce the latest version of the kit; reflect on its affordances; present the results of our most recent user studies; and discuss possible directions for future work in the area of personalized e-textile design and its relation to technology education.

The LilyPad Arduino: Toward Wearable Engineering for Everyone

Abstract: Electronic textiles, or e-textiles, are an increasingly important part of wearable computing, helping to make pervasive devices truly wearable. These soft, fabric-based computers can function as lovely embodiments of Mark Weiser's vision of ubiquitous computing: providing useful functionality while disappearing discreetly into the fabric of our clothing. E-textiles also give new, expressive materials to fashion designers, textile designers, and artists, and garments stemming from these disciplines usually employ technology in visible and dramatic style. Integrating computer science, electrical engineering, textile design, and fashion design, e-textiles cross unusual boundaries, appeal to a broad spectrum of people, and provide novel opportunities for creative experimentation both in engineering and design. Moreover, e-textiles are cutting- edge technologies that capture people's imagination in unusual ways. (What other emerging pervasive technology has Vogue magazine featured?) Our work aims to capitalize on these unique features by providing a toolkit that empowers novices to design, engineer, and build their own e-textiles.

LilyPad in the wild: how hardware's long tail is supporting new engineering and design communities

Abstract: This paper examines the distribution, adoption, and evolution of an open-source toolkit we developed called the LilyPad Arduino. We track the two-year history of the kit and its user community from the time the kit was commercially introduced, in October of 2007, to November of 2009. Using sales data, publicly available project documentation and surveys, we explore the relationship between the LilyPad and its adopters. We investigate the community of developers who has adopted the kit---paying special attention to gender---explore what people are building with it, describe how user feedback impacted the development of the kit and examine how and why people are contributing their own LilyPad-inspired tools back to the community. What emerges is a portrait of a new technology and a new engineering/design community in co-evolution.

Fabric PCBs, electronic sequins, and socket buttons: techniques for e-textile craft

Abstract: The blossoming research field of electronic textiles (or e-textiles) seeks to integrate ubiquitous electronic and computational elements into fabric. This paper concerns one of the most challenging aspects of the design and construction of e-textile prototypes: namely, engineering the attachment of traditional hardware components to textiles. We present three new techniques for attaching off-the-shelf electrical hardware to e-textiles: (a) the design of fabric PCBs or iron-on circuits to attach electronics directly to a fabric substrate; (b) the use of electronic sequins to create wearable displays and other artifacts; and (c) the use of socket buttons to facilitate connecting pluggable devices to textiles. In this work we have focused on using easily obtained materials and developing user-friendly techniques; our aim is to develop methods that will make e-textile technology available to crafters, students, and hobbyists. This paper describes the techniques and employs them as a springboard for a wider-ranging discussion of "e-textile craft".

Crafting technology: Reimagining the processes, materials, and cultures of electronics

Abstract: This article examines the practice of electronics building in the context of other crafts. We compare the experience of making electronics with the experiences of carving, sewing, and painting. Our investigation is grounded in a survey of 40 practicing craftspeople who are working in each of these disciplines. We then use this survey as a foundation for a discussion of hybrid craft—integrations of electronics with carving, sewing, and painting. We present examples of hybrid craft and discuss the ways in which blended practices can enrich and diversify technology.

Asymmetric Supercapacitor Electrodes and Devices.

Abstract: The world is recently witnessing an explosive development of novel electronic and optoelectronic devices that demand more-reliable power sources that combine higher energy density and longer-term durability. Supercapacitors have become one of the most promising energy-storage systems, as they present multifold advantages of high power density, fast charging-discharging, and long cyclic stability. However, the intrinsically low energy density inherent to traditional supercapacitors severely limits their widespread applications, triggering researchers to explore new types of supercapacitors with improved performance. Asymmetric supercapacitors (ASCs) assembled using two dissimilar electrode materials offer a distinct advantage of wide operational voltage window, and thereby significantly enhance the energy density. Recent progress made in the field of ASCs is critically reviewed, with the main focus on an extensive survey of the materials developed for ASC electrodes, as well as covering the progress made in the fabrication of ASC devices over the last few decades. Current challenges and a future outlook of the field of ASCs are also discussed.

Defining Computational Thinking for Mathematics and Science Classrooms

Abstract: Science and mathematics are becoming computational endeavors. This fact is reflected in the recently released Next Generation Science Standards and the decision to include “computational thinking” as a core scientific practice. With this addition, and the increased presence of computation in mathematics and scientific contexts, a new urgency has come to the challenge of defining computational thinking and providing a theoretical grounding for what form it should take in school science and mathematics classrooms. This paper presents a response to this challenge by proposing a definition of computational thinking for mathematics and science in the form of a taxonomy consisting of four main categories: data practices, modeling and simulation practices, computational problem solving practices, and systems thinking practices. In formulating this taxonomy, we draw on the existing computational thinking literature, interviews with mathematicians and scientists, and exemplary computational thinking instructional materials. This work was undertaken as part of a larger effort to infuse computational thinking into high school science and mathematics curricular materials. In this paper, we argue for the approach of embedding computational thinking in mathematics and science contexts, present the taxonomy, and discuss how we envision the taxonomy being used to bring current educational efforts in line with the increasingly computational nature of modern science and mathematics.

The Long Tail: Why the Future of Business is Selling Less of More

Abstract: The Long Tail: How Technology is turning mass markets into millions of niches. (p. 15). This passage from The Long Tail, pretty much sums it all up. The Long Tail by Chris Anderson is a good and worthwhile read for information scientists, computer scientists, ecommerce researchers, and others interested in all areas of Web research. The central premise of the book is that the combination of (1) the Pareto or Zipf distribution (i.e., power law probability distribution) that is characteristic of Web traffic and (2) the direct access to consumers via Web technology has opened up new business opportunities in the ''long tail''. Producers and advertisers no longer have to target ''the big hits'' at the head of the distribution. Instead, they can target the small, niche communities or even individuals in the tail of the distribution. The long tail is has been studied by Web researchers and has been noted in term usage on search engines, access times to servers, and popularity of Web sites. Andersen points out that the long tail also applies to products sold on the Web. He recounts that a sizeable percentage of Amazon sales come from books that only sell a few copies, a large number of songs from Rhapsody get downloaded only once in a month, and a significant number of movies from Netflix only get ordered occasionally. However, since the storage is in digital form for the songs and music (and Amazon out sources the storage of books) there is little additional inventory cost of these items. This phenomenon across all Web companies has led to a broadening of participation by both producers and consumers that would not have happened without the Web. The idea of the long tail is well known, of course. What Anderson has done is present it in an interesting manner and in a Web ecommerce setting. He applies it to Web businesses and then relates the multitude of other factors ongoing that permit the actual implementation of the long tail effect. Anderson also expands on prior work on the long tail by introducing an element of time, given the distribution a three dimensional effect. All in all, it is a nifty idea. The book is comprised of 14 chapters, plus an Introduction. Chapter 1 presents an overview of what the long tail is. Chapter 2 discusses the ''head'', which is the top of the tail where the …

The Maker Movement in Education

Abstract: In this essay, Erica Halverson and Kimberly Sheridan provide the context for research on the maker movement as they consider the emerging role of making in education. The authors describe the theoretical roots of the movement and draw connections to related research on formal and informal education. They present points of tension between making and formal education practices as they come into contact with one another, exploring whether the newness attributed to the maker movement is really all that new and reflecting on its potential pedagogical impacts on teaching and learning.

Mapping the landscape of sustainable HCI

Abstract: With the recent growth in sustainable HCI, now is a good time to map out the approaches being taken and the intellectual commitments that underlie the area, to allow for community discussion about where the field should go. Here, we provide an empirical analysis of how sustainable HCI is defining itself as a research field. Based on a corpus of published works, we identify (1) established genres in the area, (2) key unrecognized intellectual differences, and (3) emerging issues, including urgent avenues for further exploration, opportunities for interdisciplinary engagement, and key topics for debate.
