HTML Accessibility API Mappings 1. While some terms are defined in place, the following definitions are used throughout this document. Accessibility APIOperating systems and other platforms provide a set of interfaces that expose information about objects and events to assistive technologies. Assistive technologies use these interfaces to get information about and interact with those widgets. Examples of accessibility APIs are Microsoft Active Accessibility MSAA, Microsoft User Interface Automation UI AUTOMATION, MSAA with UIA Express UIA EXPRESS, the. Mac OS X Accessibility Protocol AXAPI, the LinuxUnix Accessibility Toolkit ATK and Assistive Technology Service Provider Interface AT SPI, and IAccessible.

It does not include objects which have relationships other than parent child in that tree. For example, it does not include objects linked via aria flowto unless those objects are also descendants in the accessibility tree. Accessibility Tree. Tree of accessible objects that represents the structure of the user interface UI. Microsoft Speech Api 5.4' title='Microsoft Speech Api 5.4' />Each node in the accessibility tree represents an element in the UI as exposed through the accessibility API for example, a push button, a check box, or container. Accessible Description. An accessible description provides additional information, related to an interface element, that complements the accessible name. The accessible description might or might not be visually perceivable. Accessible Name. The accessible name is the name of a user interface element. Each platform accessibility API provides the accessible name property. The value of the accessible name may be derived from a visible e. IC136137.gif' alt='Microsoft Speech Api 5.4' title='Microsoft Speech Api 5.4' />See related accessible description. A simple use for the accessible name property may be illustrated by an OK button. The text OK is the accessible name. When the button receives focus, assistive technologies may concatenate the platforms role description with the accessible name. For example, a screen reader may speak push button OK or OK button. The order of concatenation and specifics of the role description e. APIs or assistive technologies. Accessible object. A node in the accessibility tree of a platform accessibility API. Accessible objects expose various states, properties, and events for use by assistive technologies. In the context of markup languages e. HTML and SVG in general, and of WAI ARIA in particular, markup elements and their attributes are represented as accessible objects. Activation behavior. All 10 Seasons Of Friends For. The action taken when an event, typically initiated by users through an input device, causes an element to fulfill a defined role. The role may be defined for that element by the host language, or by author defined variables, or both. The role for any given element may be a generic action, or may be unique to that element. For example, the activation behavior of an HTML or SVGlt a element shall be to cause the user agent to traverse the link specified in the href attribute, with the further optional parameter of specifying the browsing context for the traversal such as the current window or tab, a named window, or a new window the activation behavior of an HTMLlt input element with the type attribute value submit shall be to send the values of the form elements to an author defined IRI by the author defined HTTP method. Assistive Technologies. Hardware andor software that relies on services provided by a user agent to retrieve and render Web content works with a user agent or web content itself through the use of APIs, andprovides services beyond those offered by the user agent to facilitate user interaction with web content by people with disabilities. This definition may differ from that used in other documents. Examples of assistive technologies that are important in the context. Braille display text to speech software, which is used to convert text into synthetic speech speech recognition software, which is used to allow spoken control and dictation alternate input technologies including head pointers, on screen keyboards, single switches, and sippuff devices, which are used to simulate the keyboard alternate pointing devices, which are used to simulate mouse pointing and clicking. Attribute. In this specification, attribute is used as it is in markup languages. Attributes are structural features added to elements to provide information about the states and properties of the object represented by the element. Class. A set of instance objects that share similar characteristics. Deprecated. A deprecated role, state, or property is one which has been outdated by newer constructs or changed circumstances, and which may be removed in future versions of the WAI ARIA specification. User agents are encouraged to continue to support items identified as deprecated for backward compatibility. For more information, see Deprecated Requirements in the Conformance section. Desktop focus event. Event fromto the host operating system via the accessibility API, notifying of a change of input focus. Element. In this specification, element is used as it is in markup languages. Elements are the structural elements in markup language that contains the data profile for objects. Event. A programmatic message used to communicate discrete changes in the state of an object to other objects in a computational system. User input to a web page is commonly mediated through abstract events that describe the interaction and can provide notice of changes to the state of a document object. In some programming languages, events are more commonly known as notifications. Expose. Translated to platform specific accessibility APIs as defined in the WAI ARIA User Agent Implementation Guide. WAI ARIA IMPLEMENTATIONGraphical Document. A document containing graphic representations with user navigable parts. Charts, maps, diagrams, blueprints, and dashboards are examples of graphical documents. A graphical document is composed using any combination of symbols, images, text, and graphic primitives shapes such as circles, points, lines, paths, rectangles, etc. Hidden. Indicates that the element is not visible, perceivable, or interactive to any user. An element is considered hidden if it or any one of its ancestor elements is not rendered or is explicitly hidden. Informative. Content provided for information purposes and not required for conformance. Content required for conformance is referred to as normative. Keyboard Accessible. Accessible to the user using a keyboard or assistive technologies that mimic keyboard input, such as a sip and puff tube. References in this document relate to WCAG 2. Guideline 2. 1 Make all functionality available from a keyboard WCAG2. Landmark. A type of region on a page to which the user may want quick access. Content in such a region is different from that of other regions on the page and relevant to a specific user purpose, such as navigating, searching, perusing the primary content, etc. Live Region. Live regions are perceivable regions of a web page that are typically updated as a result of an external event when user focus may be elsewhere. These regions are not always updated as a result of a user interaction. This practice has become commonplace with the growing use of Ajax. Examples of live regions include a chat log, stock ticker, or a sport scoring section that updates periodically to reflect game statistics.
