Criteria Section 1194.21 - Software Applications and Operating Systems

Supporting Features

Remarks and explanations Lexmark interprets this section to be intended for software products; we evaluate the Print driver,Status Messenger, Twain, and Network Twain driver here since they are essential to the use of the product.

(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.

Supports

Software functions are accessible through hot keys (navigableusing the TAB key); the result of the action is discernable in some text.

(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 identifiedas 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 programmaticallyexposed 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 notoverride user selected contrast and color selections and other individual display attributes.

Supports

Software applications do not disrupt or disable activated accessibility features.

Supports

Software controls display focus and are available for use through assistive technology

Supports

All images used as controls have text labels.

Supports

Bitmaps are used consistentlythroughout an application.

Supports

Textual information is provided through system functions that make the information available to assistive technology Applications do not override user selected contrast and color selections and other individual display attributes

Supports

(h) When animation is displayed, the information shall be displayable in at Not Applicable Animation is not displayed onthe drivers. 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 beprovided. (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...
