Cultural Heritage: accessible for all?SEEDI 2006 - Sofia Jan EngelenResearch group on Document Architectures Kath. Univ. Leuven (Belgium)
Overview • Introduction • “Normal” users • Reading impaired users • people with low vision, color blindness • blind persons • Available supporting equipment • Electronic document accessibility • Worldwide web • Structured documents (XML) • Other documents (PDF)
Kath. Univ. LeuvenResearch group on document architectures • Specialised in XML document management • Transformations (Omnimark language, XSLT) • Structuring: Topic Maps, Ontologies • Wordnet based search techniques • Current application domains: • Electronic reading for special groups • Newspaper article management • Geographical data management (ontology based navigation) • Online para-medical file management
Kath. Univ. LeuvenResearch group on document architectures • Involvement in 25 European Projects since 1991 including: • CAPS project choosing SGML as document format for electronic newspapers • Harmony project promoting HTML/XML as accessible formats-WAI • Omnipaper intelligent search techniques for news items • Walkonweb transborder, ontology based navigation techniques • BentoWeb, Support-EAM Web accessibility testing
Kath. Univ. LeuvenResearch group on document architectures DocArch is involved in several international activities • EU Commission • eAccessibility expert group (DG INFSO eInclusion) • Evaluation and reviewing projects • COST actions • COST219ter • Standardisation • CEN Workshops DPA and WAC • DATSCG working group • EDeAN Standardisation SIG moderator
Reading impaired users • persons with low vision(weak sight, tunnel vision, ...) • blind persons • persons with a severe motor handicap so that they cannot handle standard printed books • dyslecticsBUT ALSO • car drivers, non-english or non-chinese speaking persons, non-native speakers...
Types of low vision and colour blindness&adapted assistive equipment
Color blindness The individual with normal color vision will see a “5” revealed in the dot pattern. An individual with Red/Green (the most common) color blindness will see a “2” revealed in the dots.
Blind persons • cannot use enlarged writing anymore • rely on: • speech output • braille output: • on paper (braille embossers) • electronic (braille reading line)
speech synthesis • Several companies on the European market • many languages available • since 1998: software-only solutions • quality is approaching human read texts • problems: • linear process • difficult to interrupt without loosing orientation • no details about writing of complex words unless spelling mode (slow!!!) is used
All-in-One Notes, PDA, mobile phone (also for SMS), reading line
motor impaired persons • can often not handle books or even the keyboard • scanning systems are very popular among this group • In the past, mechanical page turners were envisaged.
Web accessibility • Guidelines, endorsed by W3C, available since 1999:WCAG1.0 • problems: • not very clear • some aspects not machine testable • WCAG2.0 : ballot is ongoing • W3C Guidelines have been accepted in many European countries; however national variants have come up as W3C is not a formal standardisation body • European research on accessibility testing and certification is ongoing.
Upcoming PDF standards • PDF/E -- ISO/CD 24517-1Document management – Engineering document format using PDF – Part 1: Use of PDF 1.6 • PDF/X -- ISO 15930-8:2006(E)Graphic technology — Prepress digital data exchange using PDF — 7 Part 8: Partial exchange of printing data using PDF 1.6 (PDF/X-5) • PDF/AAbout tagging PDF documents for accessibility
Accessible PDF from Microsoft? • Office 2007 applications will probably generate PDF directly • Beta-versions do not produce accessible PDF despite claims that PDF/A output is generated • Maybe there will be no PDF output at all...
