A Wireless Sensor Network (WSN), consisting of a huge number of small devices called sensor nodes (each with wireless communication functionality, various sensors, a processor, and a power source), is a network system that can communicate and use sensing data gathered mutually by each spatially distributed sensor node. An ad-hoc network connecting each sensor node one by one can be constructed ...

Over the past several decades dramatic increase in availability of computational resources, coupled with maturation machine learning, has profoundly impacted sensor technology. In this Perspective, we discuss sensing a focus on intelligent system design. By leveraging inverse design and learning techniques, data acquisition hardware can be fundamentally redesigned to ‘lock-in’ optimal respect u...

Recently the wireless sensor networks have emerged as an attractive solution in a number of applications. The wireless sensor networks have found many applications in different areas, including environmental surveillance, intelligent building, health monitoring, etc. In this paper we present open sensor middleware model based on SOA (Service Oriented Architecture) in wireless sensor networks. T...

We describe technology to dynamically collect information about students’ emotional state, including human observation and real-time multimodal sensors. Our goal is to identify physical behaviors that are linked to emotional states, and then identify how these emotional states are linked to student learning. This involves quantitative field observations in the classroom in which researchers rec...
