These papers detail the theoretical basis and methodical practice of HCI, the interaction of HCI with other disciplines, and individual relevance. This book is a comprehensive guide to the current research in HCI which will be essential reading for all researchers, designers and manufacturers whose work impinges on this rapidly moving field. Contributions are included from leading researchers and designers in both industry and academia.

Papers presented at HCI '91, held in Edinburgh.

Human Computer Interaction (HCI) is concerned with every aspect of the relationship between computers and people (individuals, groups and society). The annual meeting of the British Computer Society's HCI group is recognized as one of the main venues for discussing recent trends and issues. This volume contains refereed papers and reports from the 1995 meeting. The materials cover a broad range of HCI related topics, including visualization, computer supported communication, task analysis, formal methods, user support and cyberspace. The documents consider both research and commercial perspectives, making the book essential for all researchers, designers and manufacturers who need to keep abreast of developments in HCI.

Covers topics like hypertext, multimedia and graphics. Essential for designers, researchers and manufacturers.

The annual meeting of the British Computer Society's HCI group is recognised as one of the main venues for discussing recent trends and issues. This volume contains refereed papers and reports at the 1993 meeting. A broad range of HCI related topics are covered, including user interface design, user modelling, tools, hypertext, CSCW, and programming. Both research and commercial perspectives are considered, making the book 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 two-volume set LNCS 7382 and 7383 constiutes the refereed proceedings of the 13th International Conference on Computers Helping People with Special Needs, ICCHP 2012, held in Linz, Austria, in July 2012. The 147 revised full papers and 42 short papers were carefully reviewed and selected from 364 submissions. The papers included in the second volume are organized in the following topical sections: portable and mobile systems in assistive technology; assistive technology, HCI and rehabilitation; sign 2.0: ICT for sign language users: information sharing, interoperability, user-centered design and collaboration; computer-assisted augmentative and alternative communication; easy to Web between science of education, information design and speech technology; smart and assistive environments: ambient assisted living; text entry for accessible computing; tactile graphics and models for blind people and recognition of shapes by touch; mobility for blind and partially sighted people; and human-computer interaction for blind and partially sighted people.

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.
