Abstract
A system for implementing button interface compatibility for button aware applications executing on a touch-screen equipped digital imaging device. A touch-screen is coupled to the digital imaging device and is adapted to accept input from a user. An embedded computer system is built into the digital imaging device for implementing functionality for the digital imaging device. The embedded computer system includes a processor coupled to a memory, wherein the memory stores computer readable code which, when executed by the processor, causes the computer system to implement a hardware abstraction layer, a touch-screen manager, a button interface manager, and an event manager. The hardware abstraction layer is coupled to the touch-screen and is adapted to abstract the functionality of the touch-screen. The button interface manager is coupled to the touch-screen and is adapted to interface with a button aware application. The event manager is coupled to accept input from the touch-screen manager and the button interface manager, wherein the event manager interfaces a touch-screen aware application with the touch-screen by communicating with the interface manager and interfaces a button…
