Evaluating System Usability and Acceptance of a Quiz Based Augmented Reality Interaction for Learning Solutions of Electrical Motor

Abstract

Learning of electrical motor is difficult as it’s understanding requires fundamental knowledge of multidisciplinary concepts such as mechanical, electrical and electromagnetism. At the same instance, the number of enrollment for students pursuing engineering programs in the higher education is declining. In response to this, there is a need to come out with a solution to stimulate the interest of students and improve their confidence in learning the subjected materials. This study proposed the development of an innovative Augmented Reality (AR) interaction environment for learning solutions related to basic principles of electrical motor operations. The AR system is built in Android platform for smartphone suitable to be placed into a virtual reality headset. The corresponding scenarios causing malfunction of the motor are projected as quiz scenario to the participants of the study. The participants are required to come up and select the appropriate solution to identify and troubleshoot the issues based on the appearance and movement of the virtual motor. The interactions between the participants and the developed system are made through vision capturing of the finger movement of the participants using the in-built smartphone camera. Based on the results, the proposed AR system is able to stimulate the interest of the users and applicable to enhance their learning experience and problem analysis skill through the outlined features. Overall, the developed system demonstrated much potential for enhancing the learning experience of engineering education and to attract students to involve in STEM related activities.
