Web courses are widely available on the Internet. However, individualized course content for each student is hard to deal with. In this paper, we propose a new system, as well as a set of algorithms, for the automatic generation of individualized course contents and tests. The algorithms are based on a newly proposed method, called the SPC table. Experience(More)
More video streaming technologies supporting distance learning systems are becoming popular among distributed network environments. In this paper, the authors develop a multimedia authoring tool for adaptive e-learning by using characterization of extended media streaming technologies. The distributed approach is based on an ontology-based model. Suppose a(More)
—How to recognize the shape gesture for new human-computer interface without controller required and bring entertainment, games industries and information appliances in new ways. In this paper, we would illustrate a real-time hand gesture recognition system by using shape context matching and cost matrix. The shape context is taken as a basis description(More)
Hand gesture recognition is a new challenge to convey information such as input data or to control devices and applications such as computers, games, PDAs, browsers, cell phones, information appliances and MP3 audio players, etc. Image-based techniques detect a gesture by capturing pictures of a user's hand signs during the course of a gesture, and to(More)
—In this paper, we proposed an advanced Petri Net model to manage the workflow of a web-based multiple participants in virtual University. The presented approach not only can conspicuously help the developer to comprehend the interaction relationship but also to easily construct a shared and trusted virtual world. This approach was based on the scaffolding(More)
