The idea for this workshop originated when I came across and read Martin Zelkowitz's book on Requirements for Software Engineering Environments (the proceedings of a small workshop held at the University of Maryland in 1986). Although stimulated by the book I was also disappointed in that it didn't adequately address two important questions - "Whose requirements are these?" and "Will the environment which meets all these requirements be usable by software engineers?." And thus was the decision made to organise this workshop which would explicitly address these two questions. As time went by setting things up, it became clear that our workshop would happen more than five years after the Maryland workshop and thus, at the same time as addressing the two questions above, this workshop would attempt to update the Zelkowitz approach. Hence the workshop acquired two halves, one dominated by discussion of what we already know about usability problems in software engineering and the other by discussion of existing solutions (technical and otherwise) to these problems. This scheme also provided a good format for bringing together those in the HeI community concerned with the human factors of software engineering and those building tools to solve acknowledged, but rarely understood problems.

This volume contains the full papers presented at HCI 2002, the 16th annual conference of the British HCI Group. The idea of making systems memorable is one of the ways in which they can be made easier to operate but in making systems memorable it is easy to make them obtrusive. The conference aims to look at the questions of memorability and invisibility. Can systems be both memorable and invisible? Or are memorable systems far from invisible? Is an invisible and memorable system possible? And if so, what might it consist of? Do systems become memorable and invisible with familiarity even if they are initially quite difficult to use? The papers presented in this volume cover all the main areas of HCI research, but also focus on the theme of designing systems that are memorable, yet invisible, including: Interactive system design.- Interaction tools and techniques.- Users with special needs.- Virtual reality and multimedia.- Mobile interaction.- Social and cultural issues.- Psychology of programming and general computer interaction.

Software Design - Cognitive Aspects covers a variety of areas including software analysis, design, coding and maintenance. It details the history of the research that has been conducted since the 1970s in this fast-developing field before defining a computer program from a computing and cognitive psychology viewpoint. Detailed treatment is given to the two essential sides of programming; software production and software understanding and throughout the book parallels are drawn between studies on processing texts written in natural language and processing computer programs.This book will be of particular interest to researchers, practitioners and graduate students in Computer Science, Cognitive Psychology, and Cognitive Ergonomics.
