Action 501 Intent etc for discussion. 2.8.1 (former 4.8.1) Configure Position: When graphical user agent user interfaces have toolbars, the user can add, remove and configure the position of user agent user interface controls on those toolbars from a pre-defined set of controls. (Level AAA) * Intent of Success Criterion 2.8.1 (former 4.8.1) : Users with dexterity impairments or mobility impairments may have problems making the large movements required to select between non-adjacent toolbar controls which they need to use frequently. Enabling these controls to be situated together removes much the the strain, and pain, faced by these users, and increases productivity as task completion times are decreased. * Examples of Success Criterion 2.8.1 (former 4.8.1) : As part of her work as a legal secretary, Jane always needs to justify paragraphs, place them in a numbered list, and bold the first word of each list item. Because the online document processor she uses does not allow toolbars to be modified, and groups controls logically together - all paragraph formatting is grouped together, as are list manipulation and character highlighting - Jane experiences increased pain from her repetitive strain injury forcing her to take many more breaks. If the word processor allowed toolbar modification Jane could group 'justify' next to 'numbered list' next to 'bold' creating less requirement for movement and therefore less strain. * Related Resources for Success Criterion 2.8.1 (former 4.8.1) : o WAI-ARIA ==== 2.8.2 (former 4.8.2) Restore Default Toolbars: The user can restore the default toolbar configuration. (Level AAA) * Intent of Success Criterion 2.8.2 (former 4.8.2) : Mistakes happen. If a user has modified the toolbar incorrectly it can often be difficult to return to a stable state so that these errors can be corrected. There are additional pressures in this regard for people with learning difficulties who make more use of toolbars than they do of textual menus. Building an easily selectable mechanism to restore these defaults saves user time and reduces stress. * Examples of Success Criterion 2.8.2 (former 4.8.2) : Jack, is an 80 year old silver surfer who is intellectually very sharp but experiences tremors in his hands when required to make fine movements with the mouse. To help himself he is setting up the toolbar so that 'spacers' are placed between each component to prevent accidental selection of adjacent buttons. Today his tremors are particulaly bad and Jack makes a number of mistakes becoming increasingly frustrated that while trying to correct these errors he begins to make many more. Jack just wants to start over. Luckily the WebApp manufacturer has included an easy mechanism to restore the default toolbar configuration. Jack chooses this option and successfully starts over the next day. * Related Resources for Success Criterion 2.8.2 (former 4.8.2) : o WAI-ARIA Cheers Si. ======================= Simon Harper University of Manchester (UK) More: http://simon.harper.name/about/card/
