This special issue contains essays regarding the CHI '95 conference, which featured a panel titled, Discount or Disservice? Discount Usability Analysis: Evaluation at a Bargain Price or Simply Damaged Merchandise? Wayne Gray, who organized the panel, presented a controversial critique of studies that had evaluated various usability evaluation methods (UEMs). The level of interest in this discussion led Gray to propose a review article that dealt with the issues in a more systematic fashion. The resulting essay, written by Gray and his collaborator Marilyn Salzman, conducted an in-depth review of a series of influential studies that used experimental methods to compare a variety of UEMs. Gray and Salzman's analysis was framed using Cook and Campbell's (1979) well-known discussion of various forms of validity. They used this to evaluate numerous details of these comparative studies, and they concluded that the studies fell short on the criteria by which good experimental studies are designed and interpreted.

It's been known for years that usability testing can dramatically improve products. But with a typical price tag of $5,000 to $10,000 for a usability consultant to conduct each round of tests, it rarely happens. In this how-to companion to Don't Make Me Think: A Common Sense Approach to Web Usability, Steve Krug spells out a streamlined approach to usability testing that anyone can easily apply to their own Web site, application, or other product. (As he said in Don't Make Me Think, "It's not rocket surgery".) Using practical advice, plenty of illustrations, and his trademark humor, Steve explains how to: Test any design, from a sketch on a napkin to a fully-functioning Web site or application Keep your focus on finding the most important problems (because no one has the time or resources to fix them all) Fix the problems that you find, using his "The least you can do" approach By paring the process of testing and fixing products down to its essentials ("A morning a month, that's all we ask"), Rocket Surgery makes it realistic for teams to test early and often, catching problems while it's still easy to fix them. Rocket Surgery Made Easy adds demonstration videos to the proven mix of clear writing, before-and-after examples, witty illustrations, and practical advice that made Don't Make Me Think so popular.

In April 1991 BusinessWeek ran a cover story entitled, "I Can't Work This ?#!!@ Thing," about the difficulties many people have with consumer products, such as cell phones and VCRs. More than 15 years later, the situation is much the same-but at a very different level of scale. The disconnect between people and technology has had society-wide consequences in the large-scale system accidents from major human error, such as those at Three Mile Island and in Chernobyl. To prevent both the individually annoying and nationally significant consequences, human capabilities and needs must be considered early and throughout system design and development. One challenge for such consideration has been providing the background and data needed for the seamless integration of humans into the design process from various perspectives: human factors engineering, manpower, personnel, training, safety and health, and, in the military, habitability and survivability. This collection of development activities has come to be called human-system integration (HSI). Human-System Integration in the System Development Process reviews in detail more than 20 categories of HSI methods to provide invaluable guidance and information for system designers and developers.

For the last 20 years the dominant form of user interface has been the Graphical User Interface (GUl) with direct manipulation. As software gets more complicated and more and more inexperienced users come into contact with computers, enticed by the World Wide Web and smaller mobile devices, new interface metaphors are required. The increasing complexity of software has introduced more options to the user. This seemingly increased control actually decreases control as the number of options and features available to them overwhelms the users and 'information overload' can occur (Lachman, 1997). Conversational anthropomorphic interfaces provide a possible alternative to the direct manipulation metaphor. The aim of this paper is to investigate users reactions and assumptions when interacting with anthropomorphic agents. Here we consider how the level of anthropomorphism exhibited by the character and the level of interaction affects these assumptions. We compared characters of different levels of anthropomorphic abstraction, from a very abstract character to a realistic yet not human character. As more software is released for general use with anthropomorphic interfaces there seems to be no consensus of what the characters should look like and what look is more suited for different applications. Some software and research opts for realistic looking characters (for example, Haptek Inc., see http://www.haptek.com). others opt for cartoon characters (Microsoft, 1999) others opt for floating heads (Dohi & Ishizuka, 1997; Takama & Ishizuka, 1998; Koda, 1996; Koda & Maes, 1996a; Koda & Maes, 1996b).

The UX Book: Process and Guidelines for Ensuring a Quality User Experience aims to help readers learn how to create and refine interaction designs that ensure a quality user experience (UX). The book seeks to expand the concept of traditional usability to a broader notion of user experience; to provide a hands-on, practical guide to best practices and established principles in a UX lifecycle; and to describe a pragmatic process for managing the overall development effort. The book provides an iterative and evaluation-centered UX lifecycle template, called the Wheel, for interaction design. Key concepts discussed include contextual inquiry and analysis; extracting interaction design requirements; constructing design-informing models; design production; UX goals, metrics, and targets; prototyping; UX evaluation; the interaction cycle and the user action framework; and UX design guidelines. This book will be useful to anyone interested in learning more about creating interaction designs to ensure a quality user experience. These include interaction designers, graphic designers, usability analysts, software engineers, programmers, systems analysts, software quality-assurance specialists, human factors engineers, cognitive psychologists, cosmic psychics, trainers, technical writers, documentation specialists, marketing personnel, and project managers. A very broad approach to user experience through its components—usability, usefulness, and emotional impact with special attention to lightweight methods such as rapid UX evaluation techniques and an agile UX development process Universal applicability of processes, principles, and guidelines—not just for GUIs and the Web, but for all kinds of interaction and devices: embodied interaction, mobile devices, ATMs, refrigerators, and elevator controls, and even highway signage Extensive design guidelines applied in the context of the various kinds of affordances necessary to support all aspects of interaction Real-world stories and contributions from accomplished UX practitioners A practical guide to best practices and established principles in UX A lifecycle template that can be instantiated and tailored to a given project, for a given type of system development, on a given budget
