Abstract: Accessible role and state information may be included in hypertext markup language documents by encoding an accessibility definition into a class attribute. The accessibility definition corresponds with an object of a hypertext markup language document and comprises role information and state information if state information is applicable to the corresponding role information. A script is associated with the hypertext markup language document and is configured for parsing at least a portion of the hypertext markup language document to identify the accessibility definition. The script further maps the role information and the state information in the accessibility definition to corresponding namespaced role and state attributes.

Abstract: A system for providing a fully accessible color selection component in a graphical user interface, in which multiple selectable colors are represented using a set of selectable color name display regions, each of which includes a text name for a color and has a background color made up of the selectable color. Additionally, and external to the color name display regions, the disclosed system provides a sample color display region made up of a currently selected color. The background colors in the color name display regions reduce ambiguity in normal display settings by showing the user samples of colors that can be selected. The sample color display region supports high contrast settings that are likely to be used by low vision users. When a user has a high contrast setting selected, the background colors in the color name display regions may not be displayed, and accordingly the color name display regions may only display textual names.

Abstract: A system for providing DHTML (“Dynamic Hyper-Text Markup Language”) accessibility. Rich keyboard and other assistive technology (“AT”) accessibility is provided for sophisticated Web applications. When a user downloads a Web page, the system performs initialization that includes loading at least one display object, and binding the object to a predetermined event, such as, for example, a focus event. The event the object is bound to may be any semantic, device independent event. The disclosed system may also load a device handling function, such as a keyboard handling function. The device handling function associates one or more display objects with corresponding device actions, such as key presses. A keyboard handling function may operate to intercept at least one key press, and determine that an intercepted key press matches a key press corresponding to a previously loaded display object.

Abstract: Accessibility compliance is provided within advanced componentry, such as a browser in which an on-demand editor can be launched. A toolkit of functionality that is executable on a server is preferably provided, from which selections can be made to configure an instance of a client editor or similar client-side viewer. Techniques are disclosed that enable flexible specification of the controls to be added to the viewer instance, as well as specification of details for configuring the controls.

Abstract: A method and system for creating a fully accessible display object is disclosed, that may advantageously be used to provide a fully accessible object within a modal dialog box displayed in association with Web page. A fully accessible object is formed using an image command, and associated parameters, within a document containing formatting information for a user interface. The image command associates a graphical image with an software script event handler used to respond to keyboard actions of the user, such as pressing the enter key, as well as mouse actions, and also enables screen reader program access to the object. The display object formed with the disclosed system may be specifically identified and accessed with respect to the other objects of the modal dialog box through use of a the tab key on the keyboard.
