Software architecture

The Project54 in-cruiser software system was designed to be fully modular and configurable (Figure1). For each electronic device that can be controlled by the software there is a corresponding application module. Application modules are linked to each other by a simple and efficient messaging system within the core program (called the Application Manager). This messaging system allows modules to be isolated from each other in terms of their detailed functionality, greatly enhancing reliability as system configurations change, while at the same time supporting the sharing of information and command/control functionality between modules to provide the advantages of a fully integrated system. Shared services implemented as operating system drivers or run-time libraries simplify individual application modules and provide for a common look-and-feel across modules. For example the GUI application (GUI) provides access to a shared GUI service, the Logger Application provides logging services to all modules and the Proxy Application provides access to Project54 modules residing on remote computers.

Speech provides a hands off and eyes off means of communicating with the Project54 system. Speech input and output for all applications is handled by a single module, called the Speech Input/Output Application (SIOA), which in turn interacts with the commercial speech recognition and text-to-speech engines. Individual applications handle speech as text messages received from or sent to the speech module. This greatly facilitates developing new applications which communicate via speech.
