Most organisations try to protect their systems from unauthorised access, usually through passwords. Considerable resources are spent designing secure authentication mechanisms, but the number of security breaches and problems is still increasing (DeAlvare, 1990; Gordon, 1995; Hitchings, 1995). Unauthorised access to systems, and resulting theft of information or misuse of the system, is usually due to hackers "cracking" user passwords, or obtaining them through social engineering. System security, unlike other fields of system development, has to date been regarded as an entirely technical issue - little research has been done on usability or human factors related to use of security mechanisms. Hitchings (1995) concludes that this narrow perspective has produced security mechanisms which are much less effective than they are generally thought to be. Davis & Price (1987) point out that, since security is designed, implemented, used and breached by people, human factors should be considered in the design of security mechanism. It seems that currently hackers pay more attention to human factors than security designers do. The technique of social engineering, for instanc- obtaining passwords by deception and persuasion- exploits users' lack of security awareness. Hitchings (1995) also suggests that organisational factors ought to be considered when assessing security systems. The aim of the study described in this paper was to identify usability and organisational factors which affect the use of passwords. The following section provides a brief overview of authentication systems along with usability and organisational issues which have been identified to date. 1.

Currently we are at the beginnings of widespread wireless connectivity and ubiquitous computing. The Web is merging with a variety of technologies: cell phones, laptop computers, hand held organisers, information appliances, and GPS and other sensors. The capability for access anytime and anywhere is here. The increasing frequency of cell phone calls at inappropriate times testifies that people no longer can easily control access. Devices can determine where they are located and can make a range of information available to users as well as make users available to others or their devices. We have proposed a general technique that promises to assist in mediating access. It capitalises on advantages afforded by computation(Hollan & Stometta, 1992). We first described the negotiation technique in the context of problems involved in scheduling meetings and then showed that similar issues, which at first may seem unrelated but in fact have much in common, arise in other contexts. One such activity, gaining immediate access, is currently of growing importance because of expanding connectivity via wireless technology. Cell phones and related technologies make it possible to be constantly available for synchronous interaction. At times, this can be advantageous but the associated costs and benefits result in a complex tradeoff space for designers as well as users.

Human Computer Interaction (HCI) is the scientific field that is concerned with every aspect of the relationship between computers and people (individuals, groups and society). This volume provides an overview of the very latest, state-of-the-art developments in the field. It contains the refereed papers and reports from the 1994 meeting of the British Computer Society's HCI group. A broad range of HCI-related topics are covered, including interactive systems development, user interface design, user modeling, tools, hypertext and CSCW. Because both research and commercial perspectives are considered, the book will be essential for all researchers, designers and manufacturers who need to keep abreast of developments in HCI.

Disciplines, including Human-Computer Interaction (HCI), consist of knowledge supporting practices which solve general problems (Long & Dowell, 1989). A disci pline thus requires knowledge to be acquired which can be applied by practitioners to solve problems within the scope of the discipline. In the case of HCI, such knowledge is being acquired through research and, less formally, through the description of successful system development practice. Some have argued that knowledge is further embodied in the artefacts. HCI knowledge is applied to solve user interface design problems. Such applica tion is facilitated if the knowledge is expressed in a conception which makes explicit the design problems of practitioners. A conception has been proposed by Dowell & Long (1989). The conception provides a framework within which to reason about the implications of designs for system performance. The framework is concordant with the trend towards design, discernible in recent HCI research. It is further compatible with notions of top-down design, fundamental to software engineering practice. 2 Teaching and the HeI Research and Development Gap 2.1 An Assessment of Current HCI Education Teaching is one means by which practitioners learn to specify discipline problems. It is also a means by which they acquire knowledge to enable the problems to be solved.

In 2001 AFIHM and the British HCI Group combined their annual conferences, bringing together the best features of each organisation's separate conference series, and providing a special opportunity for the French- and English-speaking HCI communities to interact. This volume contains the full papers presented at IHM-HCI 2001, the 15th annual conference of the British HCI group, a specialist group of the British Computer Society and the 14th annual conference of the Association Francophone d'interaction Homme-Machine, an independent association for any French-speaking person who is interested in Human-Computer Interaction. Human-Computer Interaction is a discipline well-suited to such a multi-linguistic and multi-cultural conference since it brings together researchers and practitioners from a variety of disciplines with very different ways of thinking and working. As a community we are already used to tackling the challenges of working across such boundaries, dealing with the problems and taking advantage of the richness of the resulting insights: interaction without frontiers. The papers presented in this volume cover all the main areas of HCI research, but also focus on considering the challenges of new applications addressing the following themes: - Enriching HCI by crossing national, linguistic and cultural boundaries; - Achieving greater co-operation between disciplines to deliver usable, useful and exciting design solutions; - Benefiting from experience gained in other application areas; - Transcending interaction constraints through the use of novel technologies; - Supporting mobile users.

The need for ensuring that usability measurement results can contribute to the ongoing development of a software product in a formative way is the main theme of this paper. It is recognized that acquiring, structuring, and analysing data about the actual progression of a product's development is a challenging task. Even more difficult, is the problem of making the results of any analysis of that data readily accessible to all the participants at regular intervals in the process. The paper presents an approach to supporting that process exemplified in SEDRES (Systems Engineering Data Representation and Exchange Standardization), a European Aerospace collaborative project on developing a data exchange capability for design tools. The main subject is the role of a software tool called NUD*IST (Non-numerical Unstructured Data Indexing Searching and Theorizing) (QSR, 1997), in providing support for structuring and analysing longitudinal data and for regular feedback to the project partners about the product under development. The paper begins with an overview of the context of use, a systems engineering project involving five major companies in the European Aerospace industry. SEDRES is a three year project which started in January 1996, co-funded by an ESPRIT grant from the European Commission. The project partners comprise Aerospatiale, Alenia, British Aerospace, Daimler-Benz Aerospace, Saab and Linkoping University (Sweden), the Australian Centre for Test & Evaluation (ACTE), and Loughborough University Telecommunications and Computer-Human Interaction (LUTCHI) Research Centre.

Successful use of information and communication technologies depends on usable designs that do not require expensive training, accommodate the needs of diverse users and are low cost. There is a growing demand and increasing pressure for adopting innovative approaches to the design and delivery of education, hence, the use of online learning (also called E-learning) as a mode of study. This is partly due to the increasing number of learners and the limited resources available to meet a wide range of various needs, backgrounds, expectations, skills, levels, ages, abilities and disabilities. The advances of new technology and communications (WWW, Human Computer Interaction and Multimedia) have made it possible to reach out to a bigger audience around the globe. By focusing on the issues that have impact on the usability of online learning programs and their implementation, Usability Evaluation of Online Learning Programs specifically fills-in a gap in this area, which is particularly invaluable to practitioners.
