HIPERMÍDIAS: IntERfAcES DIgItAIS EM EA D
The methodology to determine degree of compliance with guidelines of WCAG
Accessibility (2008) according to each disability, museum sites selected, a survey
was conducted quantitative and descriptive, from April to June 2009, with studies of
relationships of variables, as presented by Lakatos and Marconi (1991). Used as sample
sites categorized by museums Virtual Library museums pages - VLmp (ICOM, 2009) as
