Computer-Based Systems in Society (CbSyS)

In this paper, we introduce a new field of systems applications, that of Computer-based Systems in Society (CbSyS). In this context, factors as topologies & architectures, sensor grids & networks, information processing etc., are combined in order to solve social problems as for instance to assist handicaps. As an introductory paradigm we develop a sensor-based system designed for the assistance of blinds, entitled B-light. This is a navigation system, object-oriented, sensor-based, which enables embedded configuration as well as networking perspective. The overall system can be composed by a multifaceted assembly of components of software and hardware. We cite herein the generic context of implementation. The analysis and presentation is vertical, beginning from the theoretical grounding of the application framework and reaching the representative implementation of an ad-hoc system. Elements of embedded systems, of sensor networks, of signal, image & information processing can be combined into any specific implementation. The anticipated benefits of the herein presented system, as well as of the general framework of CbSyS are vital since they offer solutions and improvements in critical problems in Society.
