I am an HCI reseacher with focus on improving access to computing technologies to people with different abilities, and on re-designing interactions and workflows for pervasive healthcare. Alongside, I am concerned with how people, in general, are able to secure their data, particularly from non-sophisticated insiders. I do all this with a strong user- and data-driven approach, mostly by deploying and assessing technological artifacts in-the-wild (i.e., in the real world). My work depends on a strong involvement with end-users (e.g., I am proud to be collaborating with institutions for blind people for over 12 years, with weekly engagements and prototypes being used for periods over 8 years; and with care homes, clinical centres and hospitals, in the last five years, with longitudinal (and still ongoing) deployments of our prototypes). Besides my research, I seek to have near-term impact in the life of the populations I work with by deploying functional prototypes, making them available (e.g., Braille21), or by training people in using technology. I am a Professor of Computer Science at Faculdade de Ciências da Universidade de Lisboa and a researcher at LaSIGE, where I coordinate the Accessibility and Aging Research Line.

ASSETS 2017 Paper PDFs Available

We had two short papers accepted at ACM ASSETS 2017, to be held in Baltimore, Oct 29-Nov 2. One focuses on in-context crowdsourced smartphone support for blind people. The second presents personalizable virtual overlays to improve system-wide non-visual accessibility to smartphones. Congrats to André Rodrigues, that also had his Doctoral... [Read More]
