Keith, Suzette, Floratos, Nikolaos and Whitney, Gill (2012): Certification or conformance: making a successful commitment to WCAG 2.0. In: Proceedings of the 2012 International Cross-Disciplinary Conference on Web Accessibility W4A 2012. p. 21.
The need for accessible websites is well recognized and the accessibility guidelines (WCAG 2.0) provide an important benchmark standard for measuring progress of eGoverment and commercial websites. This study was commissioned by ANEC and aimed to examine the effects of voluntary and third party certification schemes on actual conformance with web accessibility standards. A sample of 100 websites claiming voluntary or certified conformance to accessibility standards were selected from 5 European countries. In a combination of automatic tests and manual inspection it was found that simple measures of numbers of passes to WCAG 2.0 level A were highly disappointing. Closer inspection of the results revealed that a limited number of criteria at level A accounted for more than half the failures. These individual failures at level A tend to mask the commitment made by development teams to meet the needs of disabled users. Clearer processes are needed to identify and resolve these persistent barriers in order to support web development and achieve better and more consistent conformance to accessibility guidelines.

HCI issues for older people are extremely important in light of the rapidly ageing population in developed countries. In addition, technology offers great potential for this age group but will only be useful if it can be used effectively by its target users. In this workshop, we will therefore examine how HCI can address the needs and situations of this increasing older population. We aim to build up and support the research community in this area by providing a forum for the presentation of current work and a platform for discussing key challenges in this area. This workshop continues a successful series held at HCI in recent years and this year focuses on methodology, exploring how older people can be considered and included most effectively in design.

Blandford, Ann, Keith, Suzette, Butterworth, Richard, Fields, Bob and Furniss, Dominic (2007): Disrupting digital library development with scenario informed design. In Interacting with Computers, 19 (1) pp. 70-82.
In recent years, there has been great interest in scenario-based design and other forms of user-centred design. However, there are many design processes that, often for good reason, remain technology-centred. We present a case study of introducing scenarios into two digital library development processes. This was found to disrupt established patterns of working and to bring together conflicting value systems. In particular, the human factors approach of identifying users and anticipating what they are likely to do with a system (and what problems they might encounter) did not sit well with a development culture in which the rapid generation and informal evaluation of possible solutions (that are technically feasible and compatible with stable system components) is the norm. We found that developers tended to think in terms of two kinds of user: one who was exploring the system with no particular goal in mind and one who knew as much as the developer; scenarios typically work with richer user descriptions that challenge that thinking. In addition, the development practice of breaking down the design problem into discrete functions to make it manageable does not fit well with a scenario-based approach to thinking about user behaviour and interactions. The compromise reached was scenario-informed design, whereby scenarios were generated to support reasoning about the use of selected functions within the system. These scenarios helped create productive common ground between perspectives.

Blandford, Ann, Keith, Suzette and Fields, Bob (2006): Claims Analysis. In International Journal of Human-Computer Interaction, 21 (2) pp. 197-218.
One of the long-standing challenges in human-computer interaction has been the integration of usability evaluation methods within design practice. In the work reported here, the question of how to include user concerns within an unstructured, system-focused development process was investigated. The project looked into the use of Claims Analysis as a method for assessing the effects of design decisions on users' experience. Claims Analysis was found to be more difficult than expected to learn, to communicate to systems developers, and to apply effectively in practice. The work has highlighted a tension between user-centered and function-oriented design approaches and differences in values and perspectives between the human factors specialists and traditional developers involved in the study.

Curzon, Paul, Keith, Suzette, Wilson, Judy and Whitney, Gill (2004): Strategies for Finding Government Information by Older People. In: Proceedings of the 8th ERCIM Workshop on User Interfaces for All 2004. p. 34.
Governments increasingly expect web technology to become their major way of exchanging information with citizens, replacing existing methods. They also give accessibility a high priority. Older people are a major user of government services. We describe a pilot study comparing attitudes of older people to e-government with other ways of obtaining information. We examine what individuals consider important in an information search strategy, and the relative effectiveness of each for achieving an individuals personal aims. We do this in the light of research on the effects of aging on cognitive skills.

Blandford, Ann, Keith, Suzette, Connell, Iain and Edwards, Helen (2004): Analytical usability evaluation for digital libraries: a case study. In: JCDL04: Proceedings of the 4th ACM/IEEE-CS Joint Conference on Digital Libraries 2004. pp. 27-36.
There are two main kinds of approach to considering usability of any system: empirical and analytical. Empirical techniques involve testing systems with users, whereas analytical techniques involve usability personnel assessing systems using established theories and methods. We report here on a set of studies in which four different techniques were applied to various digital libraries, focusing on the strengths, limitations and scope of each approach. Two of the techniques, Heuristic Evaluation and Cognitive Walkthrough, were applied in text-book fashion, because there was no obvious way to contextualize them to the Digital Libraries (DL) domain. For the third, Claims Analysis, it was possible to develop a set of re-usable scenarios and personas that relate the approach specifically to DL development. The fourth technique, CASSM, relates explicitly to the DL domain by combining empirical data with an analytical approach. We have found that Heuristic Evaluation and Cognitive Walkthrough only address superficial aspects of interface design (but are good for that), whereas Claims Analysis and CASSM can help identify deeper conceptual difficulties (but demand greater skill of the analyst). However, none fit seamlessly with existing digital library development practices, highlighting an important area for further work to support improved usability.
