Section 1194.31 Functional Performance Criteria

(a) When software is designed to run on a system that has a keyboard, product functions shall be executable from a keyboard where the function itself or the result of performing a function can be discerned textually.

(b) Applications shall not disrupt or disable activated features of other products that are identified as accessibility features, where those features are developed and documented according to industry standards. Applications also shall not disrupt or disable activated features of any operating system that are identified as accessibility features where the application programming interface for those accessibility features has been documented by the manufacturer of the operating system and is available to the product developer.

(c) A well-defined on-screen indication of the current focus shall be provided that moves among interactive interface elements as the input focus changes. The focus shall be programmatically exposed so that Assistive Technology can track focus and focus changes.

(d) Sufficient information about a user interface element including the identity, operation and state of the element shall be available to Assistive Technology. When an image represents a program element, the information conveyed by the image must also be available in text.

(e) When bitmap images are used to identify controls, status indicators, or other programmatic elements, the meaning assigned to those images shall be consistent throughout an application's performance.

(f) Textual information shall be provided through operating system functions for displaying text. The minimum information that shall be made available is text content, text input caret location, and text attributes.

(g) Applications shall not override user selected contrast and color selections and other individual display attributes.

(h) When animation is displayed, the information shall be displayable in at least one non-animated presentation mode at the option of the user.

(i) Color coding shall not be used as the only means of conveying information, indicating an action, prompting a response, or distinguishing a visual element.

(j) When a product permits a user to adjust color and contrast settings, a variety of color selections capable of producing a range of contrast levels shall be provided.

(k) Software shall not use flashing or blinking text, objects, or other elements having a flash or blink frequency greater than 2 Hz and lower than 55 Hz.

(l) When electronic forms are used, the form shall allow people using Assistive Technology to access the information, field elements, and functionality required for completion and submission of the form, including all directions and cues.

Supporting Features

Remarks and explanations

(a) A text equivalent for every non-text element shall be provided (e.g., via "alt", "longdesc", or in element content).

 Alt and title attributes are provided for all images and input boxes.

(b) Equivalent alternatives for any multimedia presentation shall be synchronized with the presentation.

 No multi-media (video, sound, animation, etc.) presentations are used in the application.

(c) Web pages shall be designed so that all information conveyed with color is also available without color, for example from context or markup.

 All graphics using color to indicate different states (such as grayed-out buttons and active/inactive icons) have dynamic alt and title attributes that indicate their state. For example, the alt for a Save button reads “Save”, while the alt for a grayed-out button reads “Save Disabled”.

(d) Documents shall be organized so they are readable without requiring an associated style sheet.

 The application uses an external style sheet, in which style rules are set up in a separate file. The application is readable without a style sheet.

(e) Redundant text links shall be provided for each active region of a server-side image map.

Alt text is provided for active regions of image maps.

(f) Client-side image maps shall be provided instead of server-side image maps except where the regions cannot be defined with an available geometric shape.

Alt text is provided for active regions of image maps.

(g) Row and column headers shall be identified for data tables.

 The application uses 508-compliant HTML techniques to cross-index row and column headers. (<TH> tags with ID attributes, <TD> tags with HEADERS attributes.)

(h) Markup shall be used to associate data cells and header cells for data tables that have two or more logical levels of row or column headers.

  The application uses 508-compliant HTML techniques to cross-index row and column headers. (<TH> tags with ID attributes, <TD> tags with HEADERS attributes.)

(i) Frames shall be titled with text that facilitates frame identification and navigation

 The application does not make use of HTML frames. Some areas of the application scroll using <DIV> tags with scrollable overflow attributes to mimic frames, but they are not HTML frames.

(j) Pages shall be designed to avoid causing the screen to flicker with a frequency greater than 2 Hz and lower than 55 Hz.

 The application does not cause the screen to flicker.

(k) A text-only page, with equivalent information or functionality, shall be provided to make a web site comply with the provisions of this part, when compliance cannot be accomplished in any other way. The content of the text-only page shall be updated whenever the primary page changes.
