This paper investigates the capability of Kinect sensor as interactive technology and discusses how it can assist and improve teaching and learning. The Kinect sensor is a motion sensor that provides a natural user interface. It was implemented by Microsoft for the Xbox 360 video-game console to create a new control-free experience for the user without any intermediary device. The Kinect sensor can enhance kinesthetic pedagogical practices to profit learners with strong bodily-kinesthetic intelligence (body smart). As a learning tool, the Kinect sensor has potential to create interactive games, to increase learner motivation, and to enhance learning efficiency via its multimedia and multisensory capacity. Many students must learn spatial skills to improve learning achievement in science, mathematics, and engineering. This paper will focus on developing the Kinect sensor-assisted game-based learning system with ARCS model to provide kinesthetic pedagogical practices for learning spatial skills, motivating students, and enhancing students' effectiveness. The responses to the System Usability Scale indicated that our system demonstrated usability and learnability. We conclude that the Kinect sensor-assisted learning system promotes the development of students' spatial visualization skills and encourages them to become active learners.
Abstract. Wireless sensor networks consist of small nodes with sensing, computation, and wireless communications capabilities. The energy efficiency is a key design issue that needs to be enhanced to improve the life span of the network. In this paper, we propose a Hierarchy-Based Multipath Routing Protocol (HMRP) for wireless sensor networks. In HMRP, the network will be constructed to layered-network at first. Based on the layered-network, sensor nodes will have multipath route to sink node through some candidate parent nodes. The simulation results show that our HMRP can improve the lifetime of sensor networks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
