Voting difficulties hung over America's presidential election in 2000 like a dark cloud. Hanging chads, a butterfly ballot, and the Supreme Court remain the most vivid memories of that political donnybrook. Passage of 2002's Help America Vote Act sparked further interest in the physical process of casting a ballot, yet several recent contests still produced confusion at the polls. A solution to at least some of those problems may be found in new technology, but such innovations carry their own concerns and questions. V oting Technology is the first book to investigate in a scientific and authoritative manner how voters respond to the new equipment. The authors—an interdisciplinary group of experts in American elections, political behavior, human-computer interaction, and human factors psychology—assess five commercially available voting systems, each one representing a specific class based on shared design principles, as well as a prototype system not currently available. They evaluate the systems against different criteria (including ease of use, speed, and accuracy) using field experiments, laboratory experiments, and expert reviews. The results reveal the good and bad about the new systems, including specific features that contribute to clarity, confusion, or error. Going beyond the concern with spoiled ballots, they determine whether voters actually cast their ballots for the candidates they intended to support. They address fundamental questions of whether voters like and trust the equipment and whether the various systems are equally usable by all voters. Their research also opens up an entirely new line of inquiry by asking about the interaction between ballot format and voter behavior. The concluding chapter pulls together best practices that will guide manufacturers of voting systems, ballot designers, election officials, political observers, and of course, voters. In a political system based on free exercise of personal choice, the least we can do is make sure our choices are being accurately recorded and counted.

The Not-So-Simple Act of Casting a Ballot

Voting Technology

Since the beginning of the computer age, researchers from many disciplines have sought to facilitate people's use of computers and to provide ways for scientists to make sense of the immense quantities of data coming out of them. One gainful result of these efforts has been the field of information visualization, whose technology is increasingly applied in scientific research, digital libraries, data mining, financial data analysis, market studies, manufacturing production control, and data discovery. This book collects 38 of the key papers on information visualization from a leading and prominent research lab, the University of Maryland’s Human-Computer Interaction Lab (HCIL). Celebrating HCIL’s 20th anniversary, this book presents a coherent body of work from a respected community that has had many success stories with its research and commercial spin-offs. Each chapter contains an introduction specifically written for this volume by two leading HCI researchers, to describe the connections among those papers and reveal HCIL’s individual approach to developing innovations. *Presents key ideas, novel interfaces, and major applications of information visualization tools, embedded in inspirational prototypes. *Techniques can be widely applied in scientific research, digital libraries, data mining, financial data analysis, business market studies, manufacturing production control, drug discovery, and genomic studies. *Provides an "insider" view to the scientific process and evolution of innovation, as told by the researchers themselves. *This work comes from the prominent and high profile University of Maryland's Human Computer Interaction Lab
