An interactive augmented reality framework to enhance the user experience and operational skills in electronics laboratories

Resumen

Augmented reality (AR) stands as a widely embraced technology that significantly enhances learning experiences for students. AR offers an instructional approach supported by technological design, thereby fostering enriched learning interactions. This research proposes an interactive AR framework, intended to create an augmented reality learning environment (ARLE) for the specific needs of electronics engineering laboratory hardware operations. The ARLE functions as an active learning system designed using a user-centered methodology. It offers interactive 3D models of laboratory equipment, providing learners with preliminary training in equipment operation. The real-time connection between the laboratory apparatus and the AR environment is established using the Arduino board. This interface empowers users to control the AR simulation through the laboratory equipment seamlessly. An experimental study involving 80 engineering students was conducted to evaluate the impact of AR intervention on user experience, usability, and operational skills. The participants were divided into two groups: the experimental group (N = 40) and the control group (N = 40). The experimental group underwent electronics equipment training using ARLE, while the control group followed instructions from a standard instrument handbook. To assess the usability and user experience of ARLE, the system usability scale (SUS) and the user experience questionnaire (UEQ) were employed (N = 40). The findings revealed an SUS score of 80.9 for ARLE, categorizing it as “good” according to SUS ratings. Additionally, the UEQ results demonstrated significantly favorable scores across the six scales when compared to the benchmark dataset. The study’s outcomes demonstrate that AR intervention offers learners significant pedagogical value, resulting in a substantial positive impact on operational skills in electronics laboratories.
