An electronic circuit simulator for educational purposes adopting graphic human interface

The author proposes an electronic circuit simulator for educational use with special attention given to the user-friendly and easy-to-handle human interface. The system is implemented on a Macintosh personal computer using HyperCard as a developing platform. This system aims to provide an artificial environment that makes it seem as if the user were actually handling such devices as instrumenting equipment and resistors in the circuit. This environment is prepared mainly using graphical objects with an attached script program to be activated in accordance with user action. The author gives a brief summary of the software configuration and the user´s response to the designed simulator
