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 a wide 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 the field of electrical and electronics engineering was developed under these conditions, especially when the COVID-19 pandemic necessitates distance education. A QR code was identified as the marker, a booklet was prepared and it consisted of such basic circuit examples as short circuit, open circuit, circuit with series-connected resistors, circuit with parallel-connected resistors, RLC circuit, diode and LED circuit, environmental currents method and node voltage method with QR codes. When the users scan them, they can observe 3D simulations and animations of those circuit examples thanks to the AR application developed. Using Vuforia SDK as the software development kit and Unity3D as the application development platform, it was aimed to concretize abstract concepts and enhance interactive educational experiences. In addition, C# programming language was used to develop this application for smart devices with Android operating system. 30 students participated in the user study and their feedback about the AR application developed was obtained with a questionnaire. © 2022 Published by ISRES Publishing.
