Implementation of an Augmented Reality Application for Basic Electrical Circuits

Abstract

It is noteworthy that augmented reality is a technology used for educational purposes along with awide range of applications ranging from defense industry to construction, medicine to automotive. In this paper,a recognition-based AR application named ARKTUNApp that can be used on basic electrical circuits in thefield of electrical and electronics engineering was developed under these conditions, especially when theCOVID-19 pandemic necessitates distance education. A QR code was identified as the marker, a booklet wasprepared and it consisted of such basic circuit examples as short circuit, open circuit, circuit with seriesconnected resistors, circuit with parallel-connected resistors, RLC circuit, diode and LED circuit, environmentalcurrents method and node voltage method with QR codes. When the users scan them, they can observe 3Dsimulations and animations of those circuit examples thanks to the AR application developed. Using VuforiaSDK as the software development kit and Unity3D as the application development platform, it was aimed toconcretize abstract concepts and enhance interactive educational experiences. In addition, C# programminglanguage was used to develop this application for smart devices with Android operating system. 30 studentsparticipated in the user study and their feedback about the AR application developed was obtained with aquestionnaire.
