    Lighthouse has some excellent information on color and font choices.

    Someone in the Slashdot community must remember a specially spread and dithered truetype font that was intended for vision impaired folk. I recall having it and trying it in the 90's but at that time didn't need it and lost track of it. It seemed to work for me when I deliberately blurred my vision with a lens. Now that I'm older I've used the above site to help with my vision degradation but if someone has a pointer to that font I'd appreciate it since color choices and glasses only go so far.

    There is quite a bit of literature on this question. However, badly crafted studies often turn out to be measuring preference not performance. You won't find badly crafted studies in the work of Legge, those who cite him, and those who publish in the same venues.

  3. Good use of color and contrast by halcyon1234 · · Score: 1 · on GUI Design Book Recommendations?
    While whitespacing, alignment and font are all things you need to consider, don't overlook the importance of color choices. You need highly contrasting colors that are easy on the eye, and that take into account colorblind users (about 8-10% of your userbase).

    Some guidelines I wrote (for an assignment for an HCI course I just took) for color selection are:

    1. Do use dark backgrounds, and light text.
    2. Don't use adjacent colors of similar lightness.
    3. Don't use Blue as a background or for fine detail.
    4. Do use shades of Purple, Violet, Red for background. AND Do use shades of Green, Yellow, Orange for foregrounds
    5. Do make sure black-and-white and monochrome versions are legible.
    6. Don't rely on color alone.
    7. Do give high-priority data high contrast.
    8. Do use tools to check your contrast.
    9. Do check colorblind compatibility

    It's somewhat ironic that on Lighthouse.org's site if you have trouble with colour vision you wouldn't be able to tell the difference between the bold text and their links (as they are only different in colour and are not underlined in any way).

    First, the inspirational quote: "The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect." -- Tim Berners-Lee, W3C Director and Inventor of the World Wide Web

    Lighthouse.org A lot of help on designing with vision-impaired people in mind.

    And finally, (Please don't slashdot this poor guy's site)... online classic stories (Twain, H.G. Wells, etc.). It's called www.readeasily.com , and was setup specifically for vision-impaired, but with such good stories that I often go there myself.

    Yea, right. That makes for how many blind people?

    How many people of all ages have a vision impairment?

    National estimates for the overall prevalence of vision impairment vary, depending upon the definition utilized.

    * An estimated 7.9 million persons (age 6 and older) have difficulty seeing words and letters in ordinary newspaper print, even when wearing glasses or contact lenses (McNeil, 2001).
    * Approximately 8.3 million persons of all ages (3.1%) are "blind in one or both eyes or report some other trouble seeing" (Adams, Hendershot, & Marano, 1999).

    How many middle aged and older adults report some form of vision problem?

    * One in six Americans (17%), 45 years of age or older, representing 16.5 million middle-age and older adults, report some form of vision impairment even when wearing glasses or contact lenses (The Lighthouse Inc., 1995).. From here.

    Slightly pedantic response but, you asked.

    Oh really? That must have been a very advanced class of visually impaired individuals. According to the American Printing House for the Blind, approximately 10% of blind students primarily use Braille. In fact, most visually impaired students can't even read Braille. I think your tutoring claim is highly suspect. Regardless, most visually impaired people are not blind! Therefore a GUI can be very helpful even to those classified as legally blind. But of course, I'm sure you understood that distinction being a tutor of "blind" people and all.

    If it's any consolation, at least you didn't claim to teach the German Shepard to type.
