Hanson, Vicki L. (2009): Age and web access: the next generation. In: Proceedings of the 2009 International Cross-Disciplinary Conference on Web Accessibility W4A 2009. pp. 7-15. Available online

When today's young adults become 'older adults' will they exhibit difficulties with technology that appear to characterize the current older generation? This paper is intended to begin a discussion of technology experience as related to aging. The goal is to challenge some existing characterizations of older Web users and consider the implications for the future. Are technology difficulties an inescapable fact of aging? Or are there factors that will serve to equip future generations of older adults with skills that will erase or lessen these difficulties?

Trewin, Shari M., Laff, Mark R., Cavender, Anna and Hanson, Vicki L. (2008): Accessibility in virtual worlds. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 2727-2732. Available online

Virtual worlds present both an opportunity and a challenge to people with disabilities. Standard ways to make such worlds accessible to a broad set of users have yet to emerge, although some core requirements are already clear. This paper describes work in progress towards an accessible 3D multi-player game that includes a set of novel tools for orienting, searching and navigating the world.

PowerUp is a multi-player virtual world educational game with a broad set of accessibility features built in. This paper considers what features are necessary to make virtual worlds usable by individuals with a range of perceptual, physical, and cognitive disabilities. The accessibility features were included in the PowerUp game and validated, to date, with blind and partially sighted users. These features include in-world navigation and orientation tools, font customization, self-voicing text-to-speech output, and keyboard-only and mouse-only navigation. We discuss user requirements gathering, the validation study, and further work needed.

Hanson, Vicki L. and Crayne, Susan (2005): Personalization of Web browsing: adaptations to meet the needs of older adults. In Universal Access in the Information Society, 4 (1) pp. 46-58

Despite difficulties in using the Web, older adults are motivated to use it. This paper reports on work underway to ease Web access for this population. Although Web accessibility standards provide specifications that Web content providers must incorporate if their pages are to be accessible, these standards do not guarantee a good experience for all Web users. This paper will discuss user controls that make a number of dynamic adaptations to page presentation and input that can greatly increase the usability of Web pages for older users. The paper will discuss the authors original work on the topic, lessons learned, and usage patterns. Current extensions to that work are also discussed.

Hanson, Vicki L. and Richards, John T. (2004): A web accessibility service: update and findings. In: Sixth Annual ACM Conference on Assistive Technologies 2004. pp. 169-176. Available online

We report here on our progress on a project first described at the ASSETS 2002 conference. At that time, we had developed a prototype system in which a proxy server intermediary was used to adapt Web pages to meet the needs of older adults. Since that report, we field tested the prototype and learned of problems with the proxy approach. We report on the lessons learned from that work and on our new approach towards meeting the Web needs of older adults and users with disabilities. This new software makes adaptations on the client machine, with greater accuracy and speed than was possible with the proxy server approach. It transforms Web pages "on the fly", without requiring that all Web content be re-written. The new software has been in use for a year and we report here on our findings from the usage. We discuss this approach in the context of Web accessibility standards and Web usability.

Hanson, Vicki L. (2004): Taking control of web browsing. In New Review of Hypermedia and Multimedia, 10 (2) pp. 127-140

Adherence to accessibility guidelines for Web pages does not necessarily guarantee a usable or satisfying Web experience for all persons with disabilities. The needs of many of these individuals fall outside the guidelines for accessible content that most Web authors take into consideration. Many of these users wish, for example, that they simply could 'enlarge' what is on a Web page. They also express the wish that pages would be 'less confusing'. To meet these needs, Web browsers and various software applications provide for a variety of ways in which page presentations can be altered. The effects of these alterations often have unexpected consequences. Some designs accommodate these alterations better than others. This article discusses one such application that allows users to control features of Web page presentation and explores design features that facilitate such control.

Richards, John T. and Hanson, Vicki L. (2004): Web accessibility: a broader view. In: Proceedings of the 2004 International Conference on the World Wide Web 2004. pp. 72-79. Available online

Web accessibility is an important goal. However, most approaches to its attainment are based on unrealistic economic models in which Web content developers are required to spend too much for which they receive too little. We believe this situation is due, in part, to the overly narrow definitions given both to those who stand to benefit from enhanced access to the Web and what is meant by this enhanced access. In this paper, we take a broader view, discussing a complementary approach that costs developers less and provides greater advantages to a larger community of users. While we have quite specific aims in our technical work, we hope it can also serve as an example of how the technical conversation regarding Web accessibility can move beyond the narrow confines of limited adaptations for small populations.

This paper considers different ways to enhance access to the World Wide Web for persons with sensory, cognitive, or motor limitations. Paradoxically, while complex Web architectures may seem to have inhibited accessibility, they have broadened the range of points where we can try to improve it. This paper identifies these points and evaluates the advantages and disadvantages of each. In particular, it describes a project to develop a strategy to enhance access that can be distributed across multiple control points and implemented as an aggregation of Web services.

Fairweather, Peter G., Richards, John T. and Hanson, Vicki L. (2002): Distributed accessibility control points help deliver a directly accessible Web. In Universal Access in the Information Society, 2 (1) pp. 70-75

This paper describes a set of interfaces and mechanisms to enhance access to the World Wide Web for persons with sensory, cognitive, or motor limitations. Paradoxically, although complex Web architectures are often accused of impeding accessibility, their layers expand the range of points where interventions can be staged to improve it. This paper identifies some of these access control points and evaluates the particular strengths and weaknesses of each. In particular, it describes an approach to enhance access that is distributed across multiple control points and implemented as an aggregation of services.

Hanson, Vicki L. (2001): Web access for elderly citizens. In: Proceedings of the 2001 EC/NSF Workshop on Universal Accessibility of Ubiquitous Computing 2001. pp. 14-18. Available online

With elderly citizens becoming an increasingly large proportion of the population in many countries, social as well as economic considerations suggest that they must be considered in the development of current and future technologies. This paper addresses issues of Internet access, and discusses a research project designed to make the web more usable by elderly citizens. This project uses a proxy server to transcode web pages according to user-specified preferences and capabilities. Users access web pages as usual, with no specialized hardware required.

Computer programs emerge as the outcome of complex human processes of cognition, communication and negotiation, which serve to establish the meaningful embedding of the computer system in its intended use context.

-- Floyd, 1992, p. 24
