- Abstract
- "Theory weary, theory leery, why can't I be theory cheery?" (Erickson, 2002, p. 269). The field of human-computer interaction (HCI) is rapidly expanding. Alongside the extensive technological developments that are taking place, a profusion of new theories, methods, and concerns has been imported into the field from a range of disciplines and contexts. An extensive critique of recent theoretical developments is presented here together with an overview of HCI practice. A consequence of bringing new theories into the field has been much insightful explication of HCI phenomena and also a broadening of the field's discourse. However, these theoretically based approaches have had limited impact an the practice of interaction design. This chapter discusses why this is so and suggests that different kinds of mechanisms are needed that will enable both designers and researchers to better articulate and theoretically ground the challenges facing them today. Human-computer interaction is bursting at the seams. Its mission, goals, and methods, well established in the '80s, have all greatly expanded to the point that "HCI is now effectively a boundless domain" (Barnard, May, Duke, & Duce, 2000, p. 221). Everything is in a state of flux: The theory driving research is changing, a flurry of new concepts is emerging, the domains and type of users being studied are diversifying, many of the ways of doing design are new, and much of what is being designed is significantly different. Although potentially much is to be gained from such rapid growth, the downside is an increasing lack of direction, structure, and coherence in the field. What was originally a bounded problem space with a clear focus and a small set of methods for designing computer systems that were easier and more efficient to use by a single user is now turning into a diffuse problem space with less clarity in terms of its objects of study, design foci, and investigative methods. Instead, aspirations of overcoming the Digital Divide, by providing universal accessibility, have become major concerns (e.g., Shneiderman, 2002a). The move toward greater openness in the field means that many more topics, areas, and approaches are now considered acceptable in the worlds of research and practice.
A problem with allowing a field to expand eclectically is that it can easily lose coherence. No one really knows what its purpose is anymore or what criteria to use in assessing its contribution and value to both knowledge and practice. For example, among the many new approaches, ideas, methods, and goals now being proposed, how do we know which are acceptable, reliable, useful, and generalizable? Moreover, how do researchers and designers know which of the many tools and techniques to use when doing design and research? To be able to address these concerns, a young field in a state of flux (as is HCI) needs to take stock and begin to reflect an the changes that are happening. The purpose of this chapter is to assess and reflect an the role of theory in contemporary HCI and the extent to which it is used in design practice. Over the last ten years, a range of new theories has been imported into the field. A key question is whether such attempts have been productive in terms of "knowledge transfer." Here knowledge transfer means the translation of research findings (e.g., theory, empirical results, descriptive accounts, cognitive models) from one discipline (e.g., cognitive psychology, sociology) into another (e.g., human-computer interaction, computer supported cooperative work).

- 1. Introduction Web search engines and digital libraries usually expect the users to use search terms that most accurately represent their information needs. Finding the most appropriate search terms to represent an information need is an age old problem in information retrieval. Keyword or phrase search may produce good search results as long as the search terms or phrase(s) match those used by the authors and have been chosen for indexing by the concerned information retrieval system. Since this does not always happen, a large number of false drops are produced by information retrieval systems. The retrieval results become worse in very large systems that deal with millions of records, such as the Web search engines and digital libraries. Vocabulary control tools are used to improve the performance of text retrieval systems. Thesauri, the most common type of vocabulary control tool used in information retrieval, appeared in the late fifties, designed for use with the emerging post-coordinate indexing systems of that time. They are used to exert terminology control in indexing, and to aid in searching by allowing the searcher to select appropriate search terms. A large volume of literature exists describing the design features, and experiments with the use, of thesauri in various types of information retrieval systems (see for example, Furnas et.al., 1987; Bates, 1986, 1998; Milstead, 1997, and Shiri et al., 2002).

- Abstract
- Our purpose in this study is to inductively reorganize software interface menu items based an a user's process model. The proposed menu interface in this study used direct users' input, such as goals and strategies for solving their information needs, to reorganize and re-label menus. To assess its effectiveness, efficiency, and user satisfaction with actual users, we implemented and compared this new menu version to the original interface that was based upon a traditional categorical menu organization. The significance of this study is that it incorporates user process modeling into the design of the user interface, providing insights into the impact of such modeling an the usability of an information system. Results from the usability testing do indicate that the proposed menu and the traditional menu are similarly effective for users in terms of task completion time and accuracy. User preferences and debriefing comments from usability testing also indicate users preferred the user-process based arrangement of menu items as displayed. However, the types of tasks (different problem type) suggest significant differences for results in task completion time and in accuracy, sometimes favoring the new version. In other words, usable and effective menu organization depends more an the types of tasks and the domain of knowledge than mere menu organization, although menu organization is a factor in the process.
