This user interface extension is designed to expand the speaking of the number, to speak the digits individually as we would speak a phone number, and to register an automatically activated task that speaks the connection state when it changes. Turn verbal exception notification off. It is myopic to assume the only device that can control a Perk should be limited to the screen reader keypad or the keyboard. To solve this problem, the Access Engine supports pluggable Input and Output objects that can easily be extended for different devices, but do not require a rewrite of the AE to support them. The Perk developer merely has to register a command for a specific device to activate a particular task.
Commands have string representations that are specific to a particular type of device.
If a device is supplied, the user can rapidly swap the device and command string to an existing task that is currently mapped to a different device. Furthermore, the AE allows the user to install multiple devices to control the application extension. Until Java, it was not possible to have consistent cross-platform guidelines for making accessible applications. This fact has enabled IBM to write concrete guidelines about how to write accessible applications. The availability of the Java Accessibility API and its Swing implementation has enabled us to build an accessibility test tool into the SVK as a component that can be activated during normal AE operation.
