Understanding Ohm's law - enlightenment through augmented reality

This paper proposes a new interactive environment for learning the basics of electricity in series and parallel circuits using augmented reality (AR). The system allows the student to design and study electric circuits by placing symbolic cards representing resistors on a board. Then this board is overlaid by a 3D virtual circuit with its electrical components. Finally, this virtual circuit is coupled back to reality by lighting up a real bulb with intensity depending on the chosen layout. In addition, the mathematical relationship between current, resistance and voltage (Ohm's law) is presented in an information window.
