Integrate accessibility solutions into the overall "look and feel":


Integrate accessibility solutions into the overall "look and feel"

ATAG Checkpoint 4.1: Ensure that accessibility prompting, checking, repair functions and documentation are always clearly available to the author. [Priority 1]

Techniques:

  1. Modified Input Field Order: ATAG 2.0 contains ATAG Checkpoint 5.2 does not require that accessibility related controls either obscure or hinder other controls. Instead, the checkpoint emphasizes that these controls should be allotted a screen presence that is appropriate for their importance. For example, some tools have floating properties bars that display input fields appropriate to the currently selected element (see Figure 3.1.2). The relative importance of a property can be communicated to the author in several ways.

  2. Input Field Highlighting: Visibility of input fields related to accessibility may be further enhanced by visual highlighting. For example, the fields may be distinguished from others using icons (see Figure A-3), color (see Figure A-4), underlining, etc. When these methods are used, it is important to ensure that that they are consistent with the overall look and feel of the authoring tool interface (as per ATAG Checkpoint 5.1). For example, if an authoring tool uses an icon in the shape of a black dot to denote the required field, this convention might be extended so that a red dot is used to denote the accessibility-related fields. An additional consideration is that in order to meet ATAG Checkpoint 7.1, the highlighting must be implemented so that it is available through APIs, allowing an author with disabilities to access the highlighting through assistive devices (MSAA, Java Accessibility API, GNOME accessibility).

  3. Grouping Related Input Fields: In some cases, several input fields are required to be completed in order to make a single element accessible. Instead of dispersing these prompts over multiple dialog boxes, it may be more effective to draw them together into one group of controls with a visible tab or other method for accessing the group (see Figure A-5). This can have the additional benefit of allowing accessibility-related help information to be provided without confusion (see "Quick Tips" in the figure, below). The downside of placing all the accessibility related input fields in the same area is that all of them will be neglected if the author does not see the grouping.

ATAG Checkpoint 4.3: Ensure that accessibility prompting, checking, repair functions and documentation are well integrated into the tool workflow. [Priority 2]

Techniques:

ATAG Checkpoint 4.4: Ensure that accessibility prompting, checking, repair functions and documentation are naturally integrated into appearance and interactive style of the tool. [Priority 2 or 3@@]
