Hello, Our first attempt at phrasing a guideline was a narrow look at links. We were trying to make serial access (i.e. speech) as efficient as possible. Thus, if you have a list of links and the information that makes that link unique appears first, you should be able to more quickly select the appropriate link. For example, if i have a list of links to chapter headings, front loading the links with "chapter 1 - style sheets, chapter 2 - links, etc." slows down a user. They have to listen to repetitive information ("chapter") before getting to the meat of the link (chapter name). On the other hand, if we did something like, "Style sheets - chapter 2, Links - chapter 3, etc." they get the meat first. This is not the best example, but it should illustrate the problem. We were especially concerned about links because we've found that users of screen readers often tab through the links on the page as a way of skimming the contents. Upon further discussion we realized the statement applied to more than just links in lists. Thus, we broadened the recommendation to (hopefully) include "Good advice which can become critical under the stress of adverse access conditions." Are there other issues that we need to be aware of in regards to this guideline? Is it helpful? Necessary? Could it possibly create other problems? thanks, --wendy wendy chisholm researcher - human factors engineer trace research and development center university of wisconsin - madison, USA
