The proposed e-Learning system performs circuit recognition using image-processing techniques (pattern matching) that compare components in a virtual circuit with each circuit component available in the database of the VCM system.
This function searches and recognizes circuit components connected at each node in a virtually constructed circuit. Checking the differences of circuit components at each node between the circuit diagram and the circuit virtually constructed using VCM, this system detects incorrect parts in the circuit constructed using VCM and informs the user of such parts.
