A framework for managing multiprocess applications based on distributed finite-state machine approach
ABSTRACT This paper describes a framework based on a publish/subscribe paradigm for interprocess communication based on XML messages sent over a TCP/IP connection. The framework manages the exchange of data within the clients of a system and permits the definition of a specific behavior for each client using a finite-state machine approach. Whilst the server-side of the framework is able to receive and dispatch events and data, the client-side of the framework is modeled as a finite-state machine able to perform state transitions after receiving the correct message. This architecture permits the loose-coupling between producers and consumers of data and the bidirectional mapping between the design of the behavior of a system and its implementation.

ABSTRACT: The paper describes a collaborative platform to support the development and the evaluation of cars interior by using a Mixed Prototyping (MP) approach. The platform consists of two different systems: the 3D Haptic Modeler (3DHM) and the Mixed Reality Seating Buck (MRSB). The 3DHM is a workbench that allows us to modify the D model of a car dashboard by using a haptic device, while the MRSB is a configurable structure that enables us to simulate different driving seats. The two systems allow the collaboration among designers, engineers and end users in order to get, as final result, a concept design of the product that satisfies both design constraints and final users’ preferences. The platform has been evaluated by means of several testing sessions, based on two different scenarios, so as to demonstrate the benefits and the potentials of our approach.Virtual and Mixed Reality - Systems and Applications - International Conference, Virtual and Mixed Reality 2011, Held as Part of HCI International 2011, Orlando, FL, USA, July 9-14, 2011, Proceedings, Part II; 01/2011
