The event web site is http://dsai2012.utad.pt/The increase in rich and interactive content on the web has allowed the growth of the number and type of users that access them. This implies that such content should be accessible to anyone, including people with disabilities. Therefore, it should be accompanied with media alternatives (captions, audio description), which should be handled by an accessible user agent that provides support for them. This paper presents: 1) an approach with accessibility requirements following standards to include accessibility in a user agent for delivering accessible multimedia content, and based on it, 2) a conceptualization that provides an abstract user interface model with the ability to be integrated into the development process.9application/pdfeng© 2012 The Authors and Elsevier B.V.Atribución-NoComercial-SinDerivadas 3.0 EspañaWeb accessibilityUser agentMedia playerMultimediaStandardUsiXMLconference paperInformática10.1016/j.procs.2012.10.029open access25414262Procedia Computer ScienceCC/0000016750
