This paper proposes a novel e-Learning system using the mixed reality (MR) technique for technical experiments involving the construction of electronic circuits. The proposed system comprises experimenters' mobile computers and a remote analysis system. When constructing circuits, each learner uses a mobile computer to transmit image data from the circuit to the analysis system during experiment. The remote analysis system performs automated segmentation and recognition of the circuit image and automatically supplies the user with virtual measurement and the circuit behavior simulation using a segmentation-based MR technique. This proposed system is beneficial for practical use in that an experimenter who lacks sufficient circuit components, measurement instruments, or experimental facilities can learn to construct practical circuits and evaluate their behavior. The usefulness and effectiveness of the proposed system was evaluated by analyzing circuits made by 42 university students in a class. Results showing positive responses, which indicate the usefulness of the proposed system, were obtained from all the students. [For full proceedings, see ED571332.]
