The paper elaborates on the object communication mechanisms as defined in the Fuzzy Object and Behavior Modeling (FOBM) technique. In traditional object oriented systems communication between objects is achieved by applying operations on objects as an analogy to message sending. FOBM enhances inter-object communication by emphasizing messages and events and supporting broader message dispatch and resolution mechanisms, message and event weighing and attenuation, sensors, indicators, emitters, and constraints to form a powerful set of mechanisms for object interaction and manipulation. Using these mechanisms new generation systems such as virtual reality environments, complex 3D modeling and animation, and non-linear systems can be represented and implemented with significantly less effort than traditional object oriented approaches. A simple FOBM construct is used to illustrate some of these concepts.
