PCSPA 2010 will provide the participants with opportunities to discuss and explore areas related to the theory of pervasive computing, signal processing and its applications. Pervasive computing envisages one world of communicating miniature devices, sensors and actuators to provide ambient services. Building on the current technology, it is ready for a wide range of applications that support and gradually change our everyday life together with signal processing. The goal of PCSPA 2010 is to further explore both theoretical and practical issues in pervasive computing, signal processing and its applications. It also provides one platform to both researchers and practitioners for the exchange of ideas and collaboration.
