Mac OS X is designed to accommodate assistive technologies and has many built-in features to help people with disabilities. Users access most of this functionality through the Universal Access pane of System Preferences. Some of these built-in technologies take advantage of the same accessibility architecture that allows external assistive technologies to access your application.
For example, VoiceOver, the built-in spoken interface introduced in Mac OS X version 10.4, relies on the accessibility architecture to make the navigation and use of the system accessible to users with visual disabilities. If you access-enable your application, VoiceOver helps a visually impaired user use it.
