Oracle BI Applications Configuration Manager provides several accessibility features.
Screen Reader — this feature provides accessibility-specific constructs in the User Interface to improve the user-experience with a screen reader. For example, menu items are labelled with 'Menu Item', and tables and list items are provided with a radio button to enable navigation and selection using the Tab and Spacebar keys.
High contrast colors — this feature provides high-contrast-friendly visual content, in conjunction with the high-contrast mode in the browser and in the operating system.
Large fonts — this feature provides browser-zoom-friendly content in large text.
If accessibility features are not required, you should disable the above features.
