Supporting Features

Remarks and explanations

(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.


 Uses standard Windows dialogs and menus with textual feedback.

(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.


 no disruptions take place

(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.


 Focus is present and, since standard Windows interface are used, are programmatically exposed

(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.


 All interface elements are text-based.

(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.


 No special icons or images are sued to represent information.

(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.


 MS Windows functions are used in virtually all cases.

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


 Overrides are not done except in one critical situation which is made clear to the user; 256-color mode is a requirement, but only for stimulus presentation—not fro textual windows.

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


 Animation is only displayed at the specific request and control of 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.


 Color coding is never the only means of conveying information.

(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.


 A variety of color selections is available.

(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.


 Textual windows do not use flashing or blinking text.  However, since this product is designed for performing research on the visual system, such stimuli can be generated, but only at the explicit command of the user.

(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.


 Since standard Windows interfaces are used in all cases, Assistive Technology should have to access the information.
