Abstract

Methods, systems and computer readable media for automatically generating customizable user interfaces using programming patterns are disclosed. According to one method, application objects of an application computer program are analyzed to identify programming patterns. Each programming pattern is a relationship among signatures of application methods in one of the application objects. The signatures of the application methods include public interfaces of the application methods. A user interface is automatically generated for the computer program. Automatically generating a user interface includes providing for at least one of a user and a programmer of the computer program to customize mappings between the application objects and user interface elements, where the user interface elements include at least one of user interface widgets and speech grammar rules.
