Effective September 1, 2006, unless an exception is approved
by the executive director of the state agency or an exemption has
been made for specific technologies pursuant to §213.17 of this
chapter, all EIR developed, procured or changed by a state agency
shall comply with the standards described in this subchapter. Each
state agency shall include in its accessibility policy the following
(1) 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.
(2) 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.
(3) 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.
(4) 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
(5) 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.
(6) 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.
(7) Applications shall not override user selected contrast
and color selections and other individual display attributes.
(8) When animation is displayed, the information shall
be displayable in at least one non-animated presentation mode at the
option of the user.
(9) Color coding shall not be used as the only means
of conveying information, indicating an action, prompting a response,
or distinguishing a visual element.
(10) 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.
(11) 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.
(12) 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.
