An intermediate software layer, which is preferably provided by a device manufacturer, processes a list of commands and actions provided by a generic application, and assigns them to various input mechanisms, and constructs appropriate menus to display on the screen of the device. Where the application supports multiple windows, views or panes the intermediate layer is able to distinguish which part of the application has the focus and adjust the actions resulting from user inputs accordingly. Hence, the computing device is operated in such a way that a generic application, not specifically designed for the device, is able to take advantage of those unique input methods that the particular device possesses. A preferred implementation is on devices such as mobile telephones, which have no fixed paradigm for providing input and whose keyboards (where they exist) have no fixed number of input buttons.
