visualization.....why have there not been more applications?  too much over promising....make a note!  John wondered about Perseus (http://www.perseus.tufts.edu/)....how can humanities text be enhanced with other media?

citations, measures, interpretation of various numbers?

2. Universal access (adapted from Theofanos & Redish, ACM Interactions, Dec 2003, and class readings)

508 of the Rehabilitation Act:  federal agencies must provide accessible info

750 million people worldwide/54 million Americans has some kind of disability; 7.7 visually impaired

45% of Americans>60 have a disability

Jaws has 65% of market for screen reader software (http://www.freedomscientific.com/fs_products/software_jaws.asp)  (try the demo)

Guidelines:

            Write for web (short, clear sentences, bulleted lists)

            Blank ALT tags for decorative elements

            Mnemonic commands

            Clear, organized layout

            Choose words carefully (home page vs homepage)

            Use <Acronym or Abbr>

            Use a skip link at top of every page (get them to content), be explicit in links (e.g., NOT ‘more’

                        rather, ‘more of today’s news’ etc.)

            start links with relevant words, keywords, then question, etc.; NO image words!

            Use headings and code properly so screenreaders can support skimming

            Make forms text sparse and form near the top of page

Examples:

Word: homepage   Jaws says: hommapodge

Word: LiveHelp    jaws says: livahelp

Word: Medline Plus  jaws says: medlynepalus

Word: FY         jaws says: fie

Word: VA         jaws says: va
