This document provides information for developers who want to use the COM interfaces provided for the Project54™ software system.

The COM objects of relevance to the application developer are shown in Figure 1. The Application Manger, provided by Project54™ implements three objects: the logging coordinator object, the message coordinator object, and the speech output coordinator object. The applications written by developers have to implement a message handler object. All applications in the system use the GUI template object to create windows. This object, provided by Project54™, allows the creation of windows with identical looks and feels by all applications.

Figure 1 COM objects of importance to developers in the Project54™ software system

The specifications for the objects and the interfaces can be found on the following the hyperlinks above. Note that the Application Manager implements objects to deal with the speech recognition engine, the text-to-speech engine, and potentially other objects as well, each of which may have COM interfaces. However, in the Project54™ software architecture the developer does not need to know about these objects.
