The Design of 3D Cooperative Learning System With Embedded Broker

Recently, the academic community has been giving much attention to cooperative learning system, a group learning method combined with pedagogy and social psychology. It allows group members to gain knowledge through collaborations and interactions. Nowadays, most Intemet cooperative learning systems are designed to provide students mainly with a convenient online environment to study theoretical courses but rarely with a 3D （three-dimensional） virtual reality to operate practical instruments. Hence, this paper designed a 3D online cooperative learning system for operating virtual instruments. By integrating with virtual reality, remote control parameter transmission and embedded broker techniques, this system gives learners not only a cooperative learning environment via networking to jointly operate the 3D virtual instruments （for example, multi-meters, power supplies and oscilloscopes）, but also the functions of instant messages and 3D puzzles to interact with one another. Therefore, learners can effectively improve learning interests and results. Besides, the proposed embedded broker also provides service capabilities similar to that of a high-end server system, and significantly reduces the system costs.     

Video retargeting using optimized crop-and-scale

Mobile devices are increasingly powerful in multimedia transmitting and browsing. However, the small screen and different aspect ratios of mobile devices lower visual quality while watching images or videos. Video retargeting is aim at fitting an existing video into arbitrary size and aspect ratio. Previous content-aware retargeting methods are mostly high computational cost, which limits their applications on the portable devices with low computation ability. In this paper, a new crop-and-scale approach is presented to adapt video to better suit the target display. We automatically find the optimal parameters of cropping window using the dynamic programming method, and then scale it to fit the target display. The cropping window can smoothly shift during a shot to follow the movement of important objects. The retargeting results using our approach introduce no deformation and jitter effects over the whole video. Experimental results show the success of our approach on adapting a variety of source videos to small display sizes.
