Recent advances in the Internet of Things (IoT) and pervasive and ubiquitous computing provide a glimpse into the future of our planet and reveal exciting visions of many smart things: smart cities, smart homes, smart cars, and other smart spaces such as malls, workplaces, hotels, schools, and much more. Driven by a technological revolution offering “low-power many things and wireless almost everything,”...
Imminent massive-scale IoT deployments require a Cloud-Sensor architecture to facilitate an ecosystem of friction-free integration and programmability. In addition to these two functional requirements, challenging performance and scalability requirements must be addressed by any such architecture. We have introduced the Cloud-Edge-Beneath (CEB) architecture which addresses scalability and performance...
This paper firstly proposes a new algorithm for finger touch detection based on front-projected vision-based table system. The algorithm, taking advantage of shadow information, can locate possible finger touch with low complexity. An adaptive structured light method is introduced to improve the precision of touch detection effectively. Secondly, we present a new prototype system architecture and...
Pervasive computing systems are begging for programming models and methodologies specifically suited to the particular cyber-physical nature of these systems. Reactive (rule-based) programming is an attractive model to use due to its built-in safety features and intuitive application development style. Without careful optimization however, reactive programming engines could turn into monstrous power...
Advanced applications in fields such as expert system, real-time process control problem solving, machine learning require the construction, efficient access and management of large, shared knowledge bases. Such knowledge bases cannot be built using existed tools such as expert system shells, because these do not scale up, nor can be built in terms of existing database technology, because such technology...
