    • Provided is a method for navigation shortcuts to computing elements or functions on a computing device in a manner that is browser, platform and hardware independent. A computing device reserves a set of device dependent mechanisms, or access keys that may be assigned to functionality associated with a document or web page. A browser or application associated with the document or web page dynamically assigns the designated functionality to one of the reserved set access keys. The application or browser that assigns the designated functionality provides a list of the assigned access keys and a corresponding description. Certain access keys may be designated as allowing duplicate assignments. Duplicate assignments of a particular access key may be toggled, or cycled, through the respective functionalities. If the same access key is assigned to different functionalities within different application, then the meaning of the access key is determined by its context.
    • 提供了一种用于以与浏览器,平台和硬件无关的方式在计算设备上计算元件或功能的导航快捷方式。 计算设备保留一组依赖于设备的机制,或者可以分配给与文档或网页相关联的功能的访问密钥。 与文档或网页相关联的浏览器或应用程序动态地将指定的功能分配给保留的设置访问密钥之一。 分配指定功能的应用程序或浏览器提供分配的访问密钥和对应描述的列表。 可以将某些访问密钥指定为允许重复分配。 可以通过相应的功能来切换或循环特定访问密钥的重复分配。 如果相同的访问密钥被分配给不同应用程序内的不同功能,则访问密钥的含义由其上下文决定。

    • Provided is a method for assigning navigation shortcuts to computing elements in a manner that is not browser, platform or computing device specific and may, if desired, take into consideration an application, document landmark, document type, or genre. A user agent or application reserves a predefined set of access keys to represent typical navigation landmarks. Using these predefined access keys, an author and/or portal designer maps the predefined access keys to browser key equivalents, thus providing consistent navigation across an application or portal. Documents may also include predefined “genres.” An author designates a genre to the document, requests device access keys from the platform, assigns functions corresponding to the designated genre to each access key and then displays the assignments and descriptions to the user of the browser or application. Thus navigation across particular documents, document sections, and web sites within a genre is standardized.
    • 提供了一种以不是浏览器,平台或计算设备的方式为计算元件分配导航快捷方式的方法,并且如果需要,可以考虑应用,文档标记,文档类型或类型。 用户代理或应用程序保留预定义的一组访问密钥来表示典型的导航地标。 使用这些预定义的访问密钥,作者和/或门户设计者将预定义的访问密钥映射到浏览器密钥等价物,从而在应用或门户网站上提供一致的导航。 文件还可以包括预定义的“流派”。 作者向文档指定类型,从平台请求设备访问密钥,将与指定类型相对应的功能分配给每个访问密钥,然后向浏览器或应用的用户显示分配和描述。 因此,跨类型的特定文档,文档部分和网站的导航是标准化的。

    • 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. The device handling function may create a focus event for the previously loaded display object, and post the event to the display object. The display object then handles the event by visually responding to the intercepted key press, for example by changing the visual representation of the display object to be highlighted, or to otherwise indicate that the display object has been selected. The event may then also be sent to an assistive technology program, such as a screen reader program. Using the values of attributes in that display object, such as the value of the role attribute, the assistive technology program responds to the event as appropriate.
    • 用于提供DHTML(“动态超文本标记语言”)可访问性的系统。 为复杂的Web应用程序提供丰富的键盘和其他辅助技术(“AT”)可访问性。 当用户下载网页时,系统执行初始化,其包括加载至少一个显示对象,并将对象绑定到预定事件,例如焦点事件。 对象绑定的事件可能是任何语义,设备无关的事件。 所公开的系统还可以加载诸如键盘处理功能的设备处理功能。 设备处理功能将一个或多个显示对象与对应的设备动作(例如按键)相关联。 键盘处理功能可以操作以拦截至少一个按键,并且确定截取的按键按压与对应于先前加载的显示对象的键按压相匹配。 设备处理功能可以为先前加载的显示对象创建焦点事件,并将事件发布到显示对象。 然后,显示对象例如通过改变要突出显示的显示对象的视觉表示来视觉地响应被截取的按键来处理该事件,或者指示已经选择了显示对象。 然后可以将该事件发送到辅助技术程序,例如屏幕阅读器程序。 使用该显示对象中的属性值(例如角色属性的值),辅助技术程序适当地响应该事件。
