Information sensing is the basic function of Internet of Things （IoT）, by which ＂Completely Sensing＂ is implemented. Information interaction is the goal of ＂Thing-to-Thing Interconnection＂ which supports the service and application of IoT. Along with the upsurge of IoT research and application, there are much research rapidly focus on the sensing network which is mainly based on the wireless sensor network. As information sensing and interaction have been deeply studied recently, it is necessary to summarize the latest progression. Firstly, the main information sensing methods, such as data collection, cleaning, compression, aggregation and fusion, are reviewed. Secondly, a basic information interaction model is proposed and the main information interaction techniques are discussed in detail. Thirdly, some active topics about information sensing and interaction, such as new sensing techniques, energy efficiency, security and mobile sensing network, are addressed. Finally, we present the challenges for the research of both information sensing and interaction, and point out the future work in this area.
