Book Description
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.

Book Description
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.

Book Description
Welcome to the proceedings of ICCHP 2008. We were proud to welcome participants from more than 40 countries from all con- nents to ICCHP. The International Programme Committee, encompassing 102 experts form all over the world, selected 150 full and 40 short papers out of 360 abstracts submitted to ICCHP. Our acceptance rate of about half of the submissions, demonstrates the scientific quality of the programme and in particular the proceedings you have in your hands. An impressive group of experts agreed to organize “Special Thematic Sessions” (STS) for ICCHP 2008. The existence of these STS sessions helped to bring the me- ing into sharper focus in several key areas of assistive technology. In turn, this deeper level of focus helped to bring together the state-of-the-art and mainstream technical, social, cultural and political developments. Our keynote speaker, Jim Fruchterman from BeneTech, USA highlighted the - portance of giving access to ICT and AT at a global level. In another keynote by H- old Thimbleby, Swansea University, UK, the role of user-centred design and usability engineering in assistive technology and accessibility was addressed. And finally, a combination keynote and panel discussion was reserved for WAI/WCAG2.0, which we expect to be the new reference point for Web accessibility from the summer of 2008 and beyond.

Book Description
Lenovo is a global leader in the PC market, employing more than 19,000 people worldwide. Its landmark takeover of IBM’s PC division in May 2005 was a major step for the company and a huge boost for Chinese industry. The deal proved to the world that Chinese companies are not only competitive in the domestic markets but can also compete at a global level. Lenovo was founded in 1984 by 11 engineers working out of a small bungalow in Beijing. Their crisis was to create a company that would offer PCs to the Chinese people at an affordable price. Using the brand name, Legend, it promoted PC usage throughout China and developed the revolutionary Legend Chinese character card that translated English software into Chinese characters. In 1994, Legend was successfully listed on the Hong Kong Stock Exchange and in 2003 rebranded itself as Lenovo. The company went from strength to strength and dominated the Chinese market with more than 25% of market share in 2004. The IBM acquisition has marked another key milestone in the history of the company. Lenovo now has over $13 billion in annual reserves and possesses necessary infrastructure to develop its markets around the world. The company is a worldwide sponsor of the International Olympic Committee and will offer funding and support to the 2006 Winter Games in Torino and the 2008 Summer Games in Beijing. Author Ling Zhijun is well known in China for his reporting on China’s economic reform, and for his book “Jiao Feng”. This book sold over two million copies in China. The author is a seasoned reporter for the People’s Daily; based in Shanghai. Martha Avery, the translator and editor of this book in English, has translated a number of works of Chinese literature into English that have been published by such presses as Viking Penguin, WW Norton, HarperCollins, Farrar Straus Giruoux and David Godine. Her most recent authored book is Tea Road: China and Russia Meet Across the Steppe. This is an economic history of the region and was published by the Intercontinental Press (China) in 2004. Ms Avery is based in Boulder, Colorado, but travels frequently to China as business consultant for a large software distributor called Software Spectrum, Inc.

Book Description
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.

Book Description
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.

Book Description
Academic Paper from the year 2019 in the subject Computer Science - General, grade: 4.0, , language: English, abstract: This review describes or analyses the trends and best practices in Human Computer Interaction and Computer Vision. Human-Computer Interaction (HCI) is a computer user interface which the user of the system works with to achieve their given tasks and sees the system in use. Information Technology (IT) is essentially an integrated person-machine system that provides information support operations, management and decision-making. Human Computer Interaction (HCI) focuses on the interactions between human and computer systems to achieve the IT system functionality, user experience, usability, the support of user interaction effectiveness. Users are increasingly preferring the use of online business systems and so are becoming intolerant of systems which are not user friendly. The human factor is an attribute (physical or cognitive) which is specific to people that use a system and how it influences the normal operations of the system as well as the achievement of human-environment equilibriums. Surface technology eliminates input/output devices through a touch sensitive feature which plays the role of input/output devices as a result of the merger between the physical and the virtual world. Through surface technology, the user eliminates the use of GUI mediums and reduces the gap between the physical and the virtual world.There are two classes of surface technology, one for the display and the other one which uses a touch sensitive mechanism for the interpretation of user signals. New approaches and methods are now needed in HCI to equip researchers with a better understanding of designing interactive systems. There are new interactive possibilities to be explored in audio-based mobile technology. The increasing popularity of smartphones has proved the portability, adaptability and ‘always on’ capability of geo-locative interactive systems. HCI bridges the gap between humans and computing devices with respect to observation of interactions, analysis of the involved interactions and the the human consequences of the interaction. The focus of HCI is the practice of usability which includes look-and-feel features, appeal, utility, efficiency, effectiveness and safety.
