While you can use automated validators to measure whether you meet section 508 and WCAG accessibility guidelines, often making the interface usable for screen readers requires more. The validators simply tell you if you have violated one of the standard rules. It does not tell you if the user can make sense of whatever it is that has been written.
Also it should be noted that while section 508 seems mostly focused on users who use screen readers, there are a number of other disabilities that are covered as well including cognitive and other various forms of visual impairments. To truly satisfy users who need section 508 assistance you need to test with users who represent those types of users. Truthfully with many eCommerce sites failing at this, sadly the bar is set pretty low to meet their needs.
If your site has a global presence then you really need to meet the WCAG Level A or priority 1 requirements at the least. As WCAG is the standard set forth by the W3C it is best to follow what is set as a standard by this group. A great article on the differences between the two can be found here;

So I thought I’d take a look to see what lofton domains might be available. Wow, pretty much everything is gone. I started doing web design in 96 and I should have registered the .com back then. It just did not occur to me to register a domain for my personal or professional needs. By the time I decided to register a domain the .com was gone. So I took the lofton.net domain in 2000. Since then, I check every now and again to see if lofton.com might be back on the market. I know it will never be available, but I check anyway. This time I thought I’d look into jimlofton.com. Gone! What’s worse, is it looks like some old guy has taken it and is posting yearbook photos and/or reunion photos. He is also keeping track of classmates who are deceased. Seems kind of odd to do on your personal site. There does not seem to be a way to contact him on his site so I checked whois and it came back with west virginia mailing address and a verizon email.
So here is the dilemma… Is it likely that someone may mistake this guy for me? On one hand I don’t think so, but because the guy has no info on the site it’s possible. The least he could do is put a regional location so that folks will know they have the West Virginia Jim Lofton and not the Chicago Jim Lofton. Actually there are two James Lofton’s in Chicago… I don’t know the other guy. I’m the Jim Lofton who started his career as a graphic designer and went to UIC and later Depaul. That should straighten things out… no? If you haven’t registered your name or have a domain that identifies you uniquely from all the other yous out there, you may want to check into that now.
Originally, I set out to write up the differences between user experience and graphic design as there are many web designers who promote themselves as experts in usability. I was enlarging it to cover pretty much all other participants in a web project, from product owners, marketers, to developers. Many of whom speak about the importance of user experience and usability, but do not understand how to actually ensure that it is incorporated into their process. Many more of whom who have never observed anyone using the product they create. However, I am going in another direction with this post as I find myself somewhat at odds with folks in my own profession, who after years of research have finally come to view users as people. The new buzz is creating interfaces/interactions that connect to a user’s emotions.
More and more web designers are seeking to dispel the notion of the browser fold. Yet there is still the reality that users can not see all of a page’s content if it is taller than a browser window and they will potentially leave the page before discovering the additional content. There is often an email sent from the CEO or other senior manager stating that they want some graphic or link moved above the fold. This typically ruins the layout or requires major reworking to get things to fit.
I guess I should back up a bit and explain that the fold is an invisible line where the content of the page is not visible below the bottom of your browser window (and/or to the right side if there is also more content than can fit into one screen horizontally). It is borrowed from the print world where certain print formats such as newspapers and brochures are folded. The content that was most important appears on the front page before the fold to be sure that the consumer would notice it.
As of late I have been looking into what ways that I could record a usability session of an application on a Mac. Windows definitely has an edge here with the Morae application from techsmith. This is a feature rich application that captures a usability session as well as make it easy to produce some nice reports. It captures both the screen and if you have a web cam, the subject. There is nothing equivalent for the Mac. However, there are a number of tools available for Mac OS X that can perform most of the functions of Morae separately.
Stretchy layouts are not good, yet every Ã¼ber techie who has a 20 inch or larger monitor wants web sites to stretch when they open their browser to the width of the monitor. Well maybe not every Ã¼ber techie wants stretchy layouts, but enough that comment on design related message boards that it really irks me. Why is it bad, because paragraphs that span exceedingly long widths are difficult to read. This is of course assuming they are long enough to still take several lines. A single line of text is not hard to read. And, of course, if the site is only images or video, then it is not as much an issue if at all.
I completed the MS in HCI at Depaul with my last class being an independent study to build a tool for testing/researching navigation and how people acquire/find information from them. Actually, I have been researching this for the last year on and off so this was in a way more of a culmination of thoughts and reading. The main outcome was the development of a web based tool that could be used to present tasks to a user and collect data as they interact with a menu navigation system. Ultimately, the project was a continuation of Dr. Craig Miller’s research into how users conceptually navigate a hierarchical menu structure. He had developed several prototypes that used java and flat text files to present the data.
As with most academic endeavors of this kind I, the student, started with a fairly broad goal and needed to narrow it down. However, my goal was not exactly the same as Dr. Miller’s as I wanted and still want a general purpose tool that could be used for a variety of research activities related to testing website navigation and usability. Where as he and another researcher are seeking to better understand the conceptual model of users as they learn a menu and find information organized in that menu. For me, my practical work experience has lead me to see the need for an easy to use tool to help better organize/prepare complex menus for websites, especially after a site has launched. So I am first assisting Dr. Miller and the other researchers in developing a tool that will work for their testing, but also I am trying to develop it in a way that I can use to do basic testing of web usability in general.
I have produced a prototype tool and released it as an open source project. It can be found at the address below. It is in alpha (or even pre-alpha) phase so any recommendations, thoughts, or contributions will be welcomed.
UI Nav Test Tool
The project was written in PHP and uses a MySQL back-end. There is a demo and you can download the source plus the setup files from the site. If you have questions you can contact me via the project site. Essentially, the UI Nav Test tool is a very stripped down CMS with features for presenting tasks to a research participant and it also has a basic reporting page and allows the researcher to download the raw data for further analysis. While the appearance is very basic, this is intentional. As the purpose is to identify problems with labels and organization, not whether something looks pretty or not. The demo is set to use one of Dr. Miller’s content domains which is focused on understanding how people conceptualize the navigation steps they will take to find items.
