Persons with Visual Impairment who use “High Contrast” Scheme
• May have 20/200 up through 20/800 vision
• No special AT – No special PC (but may use scanner with talking OCR software)
• typically have: – COLOR ISSUES– FONT SIZE AND STYLE ISSUES– GLARE ISSUES– MAY USE A LARGE MONITOR or NOT
Persons with Visual Impairment who use special
Screen Magnification Software• May have have 20/60 – 20/200 with field
restriction up through almost totally blind
• Typically use ZoomText Xtra or Magic• PC needs double RAM, compatible video card• Screen magnification software may or may not “talk” • Users typically have:
– COLOR ISSUES– FONT SIZE AND STYLE ISSUES– GLARE ISSUES
Persons who are “Totally Blind”• May have some vision or may have
“light perception” • Typically use JAWS or Window Eyes • PC needs double RAM, compatible video card,
extra ports• May use refreshable Braille, OCR, Braille

Persons who HavePhysical Access Limitations
• May use Alternative Keyboard• May use Speech Recognition • May use an Alternative Mouse • May use “hot keys”
Button 1
Button 2
May be difficult for users with Physical access issues to “mouse” from button to button or link to link –
Be sure to build in a default selection in bold that uses the ENTER key
If possible, create the ability to Arrow through selections and press Enter to select, or use Alt + hot keys
General Accessibility• Easy to reach buttons with “Hot Key”
alternative navigation • Allow colors to change, text to wrap and
fonts to be managed using Windows tools• Use descriptive links –
RSA Policy vs. link to RSA Policy • Use Microsoft Active Accessibility, WC3
Guidelines and all levels of Bobby • Use “Alt Tags” for all graphics • Know your users but also pay local AT site/s
to review accessibility of your site ie. FBC or ACBVI
