In today's technology-laden society human-computer interaction (HCI) is an important knowledge area for computer scientists and software engineers. This paper surveys existing approaches to incorporate HCI into computer science (CS) and such related issues as the perceived gap between the interests of the HCI community and the needs of CS…

Presents principles of dialog cooperativity derived from a corpus of task-oriented spoken human-machine dialog. Analyzes the "corpus" to produce a set of dialog design principles intended to prevent users from having to initiate clarification and repair metacommunication that the system would not understand. Proposes a "more…

In spring 2005, a task force of Oregon State University librarians investigated whether undergraduates would gravitate toward subject portals tentatively named "virtual college libraries." A literature review and Web site inventory shaped our definition of a virtual college library. A preliminary needs assessment consisting of an online…

Previous works in English have revealed that disfluencies follow regular patterns and that incorporating them into the language model of a speech recognizer leads to lower perplexities and sometimes to a better performance. Although work on disfluency modeling has been applied outside the English community (e.g., in Japanese), as far as we know…

This report provides a detailed description of Chips, an interactive tool for developing software employing graphical/computer interfaces on Xerox Lisp machines. It is noted that Chips, which is implemented as a collection of customizable classes, provides the programmer with a rich graphical interface for the creation of rich graphical…

Presents a set of guidelines for the display features and content of information that should be given to the learner in a computer-generated error message. Examples of common errors and suggested message displays are given. (8 references) (CLB)

Reports a preliminary investigation into the man-machine interaction aspects of online searching, including the methodology developed for observing and recording man-machine interface in the use of online information retrieval systems. Three references are cited, and a bibliography lists 16 sources. (FM)

Presents an approach which can provide explanations to user questions in human-machine communication in a flexible way. To determine the contents of explanations, scripts are used which have different optional components organized according to the intentions of user questions to meet their information needs. (Author/LRW)

This survey elicited experts' perceptions of factors affecting development and use of interactive technologies. Responses from 196 respondents were categorized as hardware/technology, software/programs, acceptance/adoption, accessibility/ease of use, and instruction/learning/communication issues. Based on this categorization, a model of…

Describes human-computer interface needs for empowering environments in computer usage in which the machine handles the routine mechanics of problem solving while the user concentrates on its higher order meanings. A closed-loop model of interaction is described, interface as illusion is discussed, and metaphors for human-computer interaction are…

Discusses electronic commerce and presents the concept of Web assistants, human assistants working in an electronic Web shop. Presents results of a usability study of a prototype adaptive Web assistant system that show users were enthusiastic about the concept of Web assistants and its implications. (Author/LRW)

This study of scholars' judgments of information quality and cognitive authority when interacting with information on the World Wide Web is based on data from verbal protocols during the searches, search logs, and post-search interviews. Discusses predictive judgments made before scholars looked at Web pages and evaluative judgments made after.…

Quality of e-learning systems is one of the important topics that the researchers are investigating in the last years. This paper refines the concept of quality of e-learning systems and proposes a new framework, called TICS (Technology, Interaction, Content, Services), which focuses on the most important aspects to be considered when designing or…

This report describes the current version of the Why System, a script-based Socratic tutor which uses tutoring strategies formulated as production rules. The current system is capable of carrying on a dialogue about the factors influencing rainfall by presenting different cases to the student, asking for predictions, probing for relevant factors,…

Examines the development of reciprocal cooperation in dyads by allowing one subject at a time to be dependent upon a partner and then reversing this condition periodically. Subjects were 10 special education unit students who ranged in age from 10 to 16 years. (MP)
