Setting Your Accessibility Options for Oracle WebCenter Portal

Use accessibility options to optimize the application user interface (UI) for use with screen readers; to enable support of high-contrast colors; and to enable support for large fonts.

• About Accessibility Options
  When you use screen readers, there can be particular requirements for selecting menu items and resource catalog items.
• Enabling Accessibility Modes
  Use this procedure to enable accessibility modes for your interface.

About Accessibility Options

When you use screen readers, there can be particular requirements for selecting menu items and resource catalog items.

Accessibility options appear on the General panel of the Preferences page. Accessibility options assist visually and non-visually impaired users in navigating the application user interface.

Note:

Disabled actions are indicated by that action shown with grey color on a white screen background. The contrast of this shade can be difficult to discern for some users.

Enabling Accessibility Modes

Use this procedure to enable accessibility modes for your interface.

1. From your user menu in the menu bar, select Preferences.
2. On the General page, select Accessibility Settings, and choose the option you require:

   • I use a screen reader. Select this option to enhance the interface for use with screen readers.

   • I use high contrast colors. Select this option to make the WebCenter Portal user interface compatible with operating systems or browsers that have high-contrast features enabled. For example, WebCenter Portal changes its use of background images and CSS styles in high-contrast mode to prevent the loss of visual information.

     Note:

     High-contrast mode is more beneficial if you use it in conjunction with your browser or operating system high-contrast mode. Also, you can find it beneficial to use large-font mode, in addition to high-contrast mode.

     The color contrast of disabled actions—which are gray—against a white screen may be difficult to discern for some users. Because disabled actions are not selectable, this issue does not affect the use of WebCenter Portal.

   • I use large fonts. Select this option to enable browser zoom-friendly content. In default mode, most text and many containers have a fixed font size to provide a consistent and defined look. In large-font mode, text and containers are more scalable. Flexible scalability enables WebCenter Portal to be compatible with browsers that are set to larger font sizes, and to work with browser zoom capabilities.

     Note:

     If you are not using large-font mode or browser zoom capabilities, then disable large-font mode. Also, you can find it beneficial to use high-contrast mode, in addition to the large-font mode.

   After you make your selection, the changes are applied immediately.

Oracle WebCenter Portal Accessibility Features

Learn about the accessibility features of Oracle WebCenter Portal.

Topics:

• About Accessibility Features for Oracle WebCenter Portal
  Enable your users to set runtime accessibility modes that they require.
• Composer Component Settings to Generate Accessible HTML
  You can set attributes for some components in Composer to generate accessible HTML.
• Understanding Portlet Accessibility Options
  Use best practices for accessibility when you set Portlet attributes.

About Accessibility Features for Oracle WebCenter Portal

Enable your users to set runtime accessibility modes that they require.

When you give users the ability to customize a page at runtime, you must ensure that any customizations your users make can be made accessible to all users. For all components that users can create at runtime, all accessibility-related attributes are shown in the Property Inspector, where users can set them appropriately.

Composer Component Settings to Generate Accessible HTML

You can set attributes for some components in Composer to generate accessible HTML.

You can add Composer components to your application pages to make them editable at runtime. Refer to the following table to see which components you can use to generate accessible HTML.

Table 18-1 Components With Accessibility Attributes for Composer

Purpose of Component	Component	Accessibility Attributes
Image link accessibility.	pe:imageLink	shortDesc—Mandatory. This attribute transforms into an HTML alt attribute. accessKey—Optional. This attribute sets the mnemonic character used to gain quick access to the component.
Page layout accessibility.	pe:layoutCustomizable	shortDesc—Mandatory. This attribute transforms into an HTML alt attribute. accessKey—Optional. This attribute sets the mnemonic character used to gain quick access to the component.
Frame layout accessibility	cust:showDetailFrame	shortDesc—Mandatory. This attribute transforms into an HTML alt attribute.

The components listed in the following table do not have accessibility modes that you can set.

Table 18-2 Components With No Accessibility Attributes for WebCenter Portal Composer

Component	Accessibility Attributes
pe:changeModeButton	No accessibility attributes
pe:changeModeLink	No accessibility attributes
pe:pageCustomizable	No accessibility attributes
cust:panelCustomizable	No accessibility attributes

Understanding Portlet Accessibility Options

Use best practices for accessibility when you set Portlet attributes.

Modern screen readers do not work well with IFrames. Some accessibility standards do not permit their use at all.

Note:

Portlets created using the Oracle JSF Portlet Bridge have the requireIFrame container runtime option set to true. This default is because, due to JavaScript issues, these portlets are too complex to render directly on Oracle ADF pages.

WebCenter Portal provides an optional attribute in the adf:portlet tag called renderPortletInIFrame. You can set this attribute to false to avoid ever using IFrames.

Keyboard Workarounds for Oracle WebCenter Portal

The Feedback Posts and Favorites features have workarounds for keyboard shortcut issues.

Working with Feedback Posts

When working with feedback posts, you cannot use the keyboard to select a date from the calendar that pops up when you click the Select Date icon. Instead, manually enter the date into the field.

Working with Favorites

When working with favorites, you cannot move a favorite into an existing folder using only the keyboard. To work around this issue, create a duplicate favorite within the target folder, and then delete the original favorite.
