Hi Daniel, The definitive resource for making websites and web applications accessible is the Web Content Accessibility Guidelines (WCAG) 2.0 from the W3C Web Accessibility Initiative. It is introduced in the WCAG Overview at: * http://www.w3.org/WAI/intro/wcag From that page you can get to: * WCAG 2 at a Glance http://www.w3.org/WAI/WCAG20/glance/ which gives you a quick overview * How to Meet WCAG 2.0 http://www.w3.org/WAI/WCAG20/quickref/ which you can customize to show you the information you are interested in WCAG is a technical standard that can be used as a checklist to ensure that you are covering all accessibility issues. WCAG itself is *not* an introduction to accessibility, nor a simple tutorial. You'll need to get that elsewhere. Here are some places to start: * Accessibility - W3C http://www.w3.org/standards/webdesign/accessibility * How People with Disabilities Use the Web http://www.w3.org/WAI/intro/people-use-web which links to the in-progress draft at http://www.w3.org/WAI/EO/Drafts/PWD-Use-Web/2009/ * Involving Users in Web Projects for Better, Easier Accessibility http://www.w3.org/WAI/users/involving I think that last doc will be especially important for your situation! It helps you understand real-world accessibility issues, such as how your target users will use the website you are developing. (Consider following some of the links, specifically http://uiaccess.com/accessucd/interact.html which I think will help with how you refer to your target users, e.g., you probably want to avoid these people when talking about your users.) The first part of that doc mentions the benefits. The specific guidance starts at http://www.w3.org/WAI/users/involving#range Hope this helps! As always, W3C WAI welcomes feedback!

It helps you understand real-world accessibility issues, such as how your target users will use the website. Yes, all that is good advice, also if your not already doing so, learn about CSS and separating mark-up and presentation as it makes writing accessible websites much easier. As screen readers don't need to wade through a bunch of tables and presentation specific mark-up. Also, use headings properly, eg don't just use a heading to make content larger, use a CSS class for that. *** List Guidelines: http://webstandardsgroup.org/mail/guidelines.cfm Unsubscribe: http://webstandardsgroup.org/join/unsubscribe.cfm Help: memberh...@webstandardsgroup.org ***

Re: [WSG] Site for Vision Impaired
It also depends what type of visual impairments. For example, there are like 6 types of color blindness allow, all which distort the colors in varying ways. If you're just talking about low vision, then you want to have larger fonts then normal. I'd say probably bump up the body font size one notch (so maybe 16 instead of 14), but also, as others have said, be flexible to user size changes. Also, make sure you have very good contrast between your background and foreground. For vision impaired, it's likely to be better if you use a soft blue or yellow (very light) background with dark (not black, maybe #333) text, instead of white on black, because it causes less eye strain.

It would be greatly appreciated. Apart from letting the user decide the font, some visual impairments mean you can't rely on the user using your colour scheme at all either. Such people will override the whole colour scheme to one suitable for them by using their own css for specific colour combinations. I have no idea what the guide lines are in such a situation. Also consider people who might use a screen reader to have your website read to them rather than view it. They might prefer if you can get extensive menu options out the way instead of having them at the start of each page. They can get to the content quicker but it isn't SEO friendly. Forget about image maps, flash and fancy roll-over stuff and avoid using colours that are difficult to differentiate for varying values of ability to differentiate. Google shows a number of links on website accessibility - you might better info there. -- Kind Regards Lesley Binks *** List Guidelines: http://webstandardsgroup.org/mail/guidelines.cfm Unsubscribe: http://webstandardsgroup.org/join/unsubscribe.cfm Help: memberh...@webstandardsgroup.org ***

And ensure the site will hold when scaled at twice user default.

Re: [WSG] Site for Vision Impaired
Hi Daniel, It maybe has incorrectly become a by-word for accessibility, but web standards are certainly your first step to provide sites for vision or indeed other disability needs. I was wondering if any of you have done any work on sites for the visually impaired? I have never specifically done a site for an audience explicitly identified as visually impaired, I've has presumed that users of any site maybe impaired and worked from that premise. What are the considerations I need to take into account with a project like this? eg ability to change contrast, text size etc? Are there any good resources or advice you could share with me? It is a considerable subject area and there are a vast array of tools and resources, but here are a few modest suggestions. The good people of Think Vitamin have made available all their tutorial videos for accessibility for free; http://membership.thinkvitamin.com/library/accessibility/?cid=106 Vision Australia has a number of very good resources and are focused on vision issues; http://www.visionaustralia.org.au/info.aspx?page=740 Formerly of Vision Australia was a gentleman called Steve Faulkner, he created the Web Accessibility Toolbar, and is now in the USA with the Paciello Group and they to have a number of useful tools and resources; http://www.paciellogroup.com/index.php It would be greatly appreciated. The only other consideration I would encourage you to think about is the content. If your clients are visually impaired then whilst a pleasing design a good thing, not at the expense of the information your audience is after. Hope this is helpful, Cheers, John Unsworth *** List Guidelines: http://webstandardsgroup.org/mail/guidelines.cfm Unsubscribe: http://webstandardsgroup.org/join/unsubscribe.cfm Help: memberh...@webstandardsgroup.org ***
