11.3 Objective

The objective of these mobile accessibility guideline is to help developers, designers and testers to create mobile apps that are universally accessible. An accessible application is one which is usable by everyone irrespective of their abilities. These mobile accessibility practices have been formulated after reviewing various globally accepted standards and guidelines, as mentioned in the section on the international position on Mobile app standards.

The Mobile Accessibility practices discussed below are not technology specific, but the examples are based on either Apple iOS or Google Android operating systems. The other mobile platforms are not used widely. The techniques to test or implement a specific practice may differ depending on the operating system.

Both the Android and iOS operating systems provide standardized mechanisms to communicate various attributes of a user interface element (UI Element) such as the label associated with a UI element, role of a UI element (such as whether it is a button or an edit control,) and state information (such as whether it is disabled, checked or pressed.) This mechanism is called Accessibility Application Programming Interface (API) and it provides reasonably good information for standard UI elements.
