I am interested in the human factors that influence the interaction of people on the World Wide Web. My current research is focused on the coping strategies that users adopt when they encounter problems on the Web. To do so, I am exploring the similarities between edge-interaction cases and the problematic interactions faced by people with disabilities on the Web. You can check the progress of the research on the COPE project website.
I got my PhD in Computer Science at the University of the Basque Country on web accessibility assessment, focusing on evaluation and measurement. I am active in the web information access domain through the W4A Steering Committee and the W3C RDWG. The W3C Research Report on Web Accessibility Metrics is one of our latest efforts in injecting research outcomes into standardisation bodies.

Behaviour & Information Technology
We asked over 300 people to answer questions surrounding the relationship between accessibility, user experience (UX) and usability; inclusion, and exclusion; and evaluation, in an attempt to harmonise our understanding of web accessibility. Respondents think that accessibility and usability are highly related and also think that accessibility is applicable to everyone and not just people with disabilities. They strongly agree that accessibility must be grounded on user-centred practices and that accessibility evaluation is more than just inspecting source code, however, they are divided as to whether training in WCAG is necessary or not to assess accessibility.
International Journal of Human-Computer Studies
We identify 17 tactics employed to overcome situations of uncertainty, reduced mobility, confusion and overload. These tactics are novel in that they are contextualised and complete: their presence denotes the presence of specific problems. Therefore these tactics are behavioural markers of cognitive processes that indicate problematic situations. We highlight the importance of these behavioural markers for designers and tools in order to remove the need to cope, evaluate accessibility-in-use and inform navigational models.
Universal Access in the Information Society
This special issue collects the extended and revised versions of the best papers that were presented at the 1st Mobile Accessibility Workshop. The papers focus on: gestures as a way to overcome accessibility problems experienced when using speech dialogue systems; sound, in the context of emergency calls made by the deaf; the problems related to requiring visual feedback for text entry in mobile devices in a situated impairment perspective; and the use of touch-screen devices by motor-impaired users.
15th ACM SIGACCESS Conference on Computers and Accessibility, ASSETS 2013
We examine the role played by subjective dimensions, and particularly expectations, on the perception that users have on web accessibility. Our preliminary findings corroborate that expectations, which are built up on previous experiences and prejudices, can affect the perception of web accessibility. Results indicate that these expectations are not only shaped by previous Web usage, but also by real life experiences.
