Section 508 Accessibility Criteria
Support Status
Explanation
(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.
Supported with exceptions
Exceptions include the following:
  • There are no keyboard equivalent keys to zoom, pan, lens and highlight the diagram.
  • There are no keyboard keys available to de-select the observation or variable once it is selected.
  • There are no keyboard equivalent keys to minimize, maximize, and close the child windows.
(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.
Supported
The software does not disrupt or disable any of the keyboard accessibility features incorporated within the operating system.
(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.
Supported with minor exceptions
On-screen indication of the current focus is provided except in the following cases:
  • In the diagram window, the visual focus indicator is not prominent.
  • Tab navigation skips over the icon toolbar. However, the toolbar commands are available from the application menu.
(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.
Supported with exception
Most interface elements, including menu bar options and shortcut keys, are read by a screen reader. However, JAWS is not able to read the data tables
(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.
Supported
Images are used consistently throughout the interface.
(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.
Supported
The software uses standard operating system functions for displaying text.
(g) Applications shall not override user selected contrast and color selections and other individual display attributes.
Supported
The software inherits user-selected contrast and color selections for display attributes to the extent supported by the platform.
(h) When animation is displayed, the information shall be displayable in at least one non-animated presentation mode at the option of the user.
Not applicable
The software contains no animation.
(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.
Supported
Color alone is not used to convey meaning.
(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.
Supported with minor exceptions
The software offers user options to enable users to choose alternating row colors for grids to ensure ample color contrast for a range of vision abilities.
(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.
Supported
The software uses no flashing or blinking elements beyond the system caret.
(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.
Supported
Compatibility with assistive technology was assessed using JAWS screen reader version 9.
