The Design of Circuit-Measuring Collaborative Learning System with Embedded Broker

Collaborative Learning System is a group learning method combined with pedagogy and social psychology. It allows group members to gain knowledge through collaborations and interactions. Nowadays, most Internet collaborative learning systems are designed to provide students mainly with a convenient online environment to study theoretical courses but rarely with an online environment to operate practical instruments. Hence, this paper describes the design of a 3D online collaborative learning system for operating virtual instruments with circuit-measuring function. The proposed system functions give learners not only a collaborative learning environment via networking to jointly operate the 3D virtual instruments but also the functions of instant messages and 3D puzzles to interact with one another by integrating with Virtual Reality, Remote Control Parameter Transmission and embedded system techniques. 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.
