Description

« Hide

Where icons are used to indicate the type of resource or the destination of a link this needs to be conveyed to screen-reader users in the link text. E.g. <pdf icon> <link: interesting article (PDF)>. (It is not necessary to add anything when it is clear from the text link, e.g. "news forum".) P1. Note it is not sufficient to just add alt text to these icons to convey this information because when screen-readers create a list of links the images will not be included and so the information will not be available in that context.

maybe the description could be hidden, possible solution described in http://www.webaim.org/techniques/css/invisiblecontent/

Added the type of the resource in the text link. This will show if the user sets his screenreader setting. I think it is also possible to include the icons into the link so that they get displayed together, and since the icons have alt tag it would also solve this problem?

Hi Chetz,

In 1.8, go to your profile, set Screenreader to true, and return to any course home page, you will see resource types in brackets.

Cheers,

Reopened - the "screenreader" flag is bad, and in this case unnecessary:

Petr's idea 23/Nov/06 was fine - we have the this pattern, http://docs.moodle.org/en/Development:Accessibility_notes#Pattern_2:_accesshide
Or, the image could be in the link - use it's ALT text - I prefer this for simplicity!

Partial fix in HEAD and 1.8 branch, because 1.8.3 is imminent.

IMPORTANT: not complete!

Hopefully the definitive patch, affecting 3 files, tested in Firefox, IE, JAWS:

theme/standard/styles_font.css - fix icon/link underline via class "img-text"
lib/filelib.php - new "mimeinfo_from_icon" function.
course/lib.php, several points:
1. For file resources get description ALT text via icon.
2. If this description is contained in the $instancename text make ALT empty - avoid duplication.
3. The TITLE is unnecessary for <a /> link.
4. Image has empty TITLE to suppress IE tooltip - so all links match.

I have committed the patch above to HEAD/ 1.9 and 1.8 branches.
Some points:

I deemed it important for 1.8.3 because the original fix, using the "screenreader" flag (~~MDL-7487~~, MDL-11348) was so broken,
Finally screen reader users see the type of a file,
And avoid unnecessary duplication, including in the link TITLE!
This solution needed creative thinking, and Chetz's help!

Some examples, including for ~~MDL-11161~~:

[Forum icon] News forum - duplicate, empty ALT, JAWS says "...link News forum".
[Resource icon] A random web page - JAWS says "...link graphic Resource A random web page..." (or language equivalent!)
[Resource icon] Course resource - duplicate, empty ALT, JAWS says "... link Course resource..." (or lang...)
[Word icon] Course introduction - JAWS says "... link graphic Word document Course introduction..." (or lang...)

Further fix applied under ~~MDL-11161~~. The above examples now are:

[Forum icon] News forum - duplicate, empty ALT, JAWS says "...link News forum".
[Resource icon] A random web page - JAWS says "...link A random web page Resource" (or language equivalent!) - hidden text.
...
[Word icon] Course introduction - JAWS says "... link Course introduction Word document" (or lang...) - hidden text.
