SPEAR: Social Presence Enabled Augmented Reality Tool for Engineering Education
Publication: Computing in Civil Engineering 2023
ABSTRACT
This paper presents the development of a novel AR-based learning application named Social Presence-Enabled Augmented Reality (SPEAR) that presents opportunities for online peer learning through mobile devices. The app was developed using an AR Foundation framework in the Unity game engine. The learning module included in the app is structural beam-bending. The app allows users to place 3-dimensional (3D) virtual models of structural beams into the real-world environment. The users can then change the load and its position on the beam. A C# script for the finite element method was created to simulate the beam’s deformation based on the magnitude of load and load positions. In addition, the moment and shear diagrams based on the load and load position can be visualized in real time. Moreover, the voice chat feature was added to the application using a cloud-based server, Voice for Photon Unity Networking (PUN) 2, which delivers the feeling of social presence that is integral to online learning. This study demonstrates the technical feasibility of developing advanced visual and interactive learning materials for online engineering students in AR environments. As a prototype online-learning platform, the SPEAR app will allow researchers to test different learning theories and learning material designs generating new knowledge to improve online engineering learners’ motivation, self-confidence, and performance.
