SIGCHI

As the newly-appointed SIGCHI Standards Liaison, I hope to continue in the fine tradition established by Jon Meads over the past several years. As I see it, my primary task is to inform SIGCHI members about any standards activities that may affect them ...

The Visual System Browser is a tool for viewing the static structure of a software system in terms of trees representing the procedure calls. The focus in the browser's construction was on the ease of use and the flexibility of what can be seen. These ...

Contextual field research is a growing area of interest in human-computer interaction. At the CHI '88 conference, Karen Holtzblatt, Sandy Jones, and myself hosted a Special Interest Group on "Field Research Techniques for Building Usable Products." This ...

Sixty-three subjects completed 24 tasks using a menu driven computer program. The menu items appeared in a fixed (static) order during 12 of the tasks. During the other 12 tasks the menu item order changed dynamically such that the most frequently ...

Though user-interface researchers and designers give similar definitions for the concept of modes in interactive systems and devices, informal evidence suggests that they don't always agree on whether or not particular interfaces are moded. A survey was ...

In a paper presented at the 1987 CHI conference (Young & Barnard, 1987), we proposed the use of scenarios as one methodological route to the development of user models of broader scope. In this article we summarise the argument and present five such ...

Improvement of the human computer interface (HCI) is receiving increasing attention as a panacea for many information systems problems; particularly end-user performance. Several experimental research efforts have made significant contributions toward ...

Analytical models are extremely useful and important tools for design engineering in many fields. They provide engineers with performance predictions for a specified design, and they also can assist in design improvements by identifying the sources of ...

This article is a combined trip report and review of the published proceedings of the CSCW '88 Conference on Computer-Supported Cooperative Work. The conference proceedings are available from ACM Order Department, PO Box 64145, Baltimore, MD 21264, $22 ...

As a formal academic discipline, Cognitive Science is difficult to describe and even that much harder to teach. This text, however, appears to have done an admirable job of providing a coherent introduction to a new discipline which draws from a number ...

Beginning computer science students frequently ask their professors to recommend a book about C programming. These students usually know Pascal, have a vague idea that C is an important language, and know that C will be used in their upper level courses ...

This book examines the use of structured and unstructured induction to design rule-based expert systems in situations which may be too complex to be coded using conventional techniques. It aims to offer a solution to the problem that the complexity of ...
