Effect of Interactive Virtual Reality on the Teaching of Conceptual Design in Engineering and Architecture Fields

This research paper explores the impact of immersive virtual reality (IVR) on the teaching of conceptual design in engineering and architecture fields, focusing on the use of interactive 3D drawing tools in virtual and augmented reality environments. The study analyzes how IVR influences spatial understanding, idea communication, and immersive 3D sketching for industrial and architectural design. Additionally, it examines user perceptions of virtual spaces prior to physical construction and evaluates the effectiveness of these technologies through surveys administered to mechanical engineering students utilizing VR/AR headsets. A structured methodology was developed for students enrolled in an industrial design course, comprising four phases: initial theoretical instruction on ephemeral architecture, immersive 3D sketching sessions using Meta Quest 2 and Microsoft HoloLens 2 VR/AR headsets, detailed CAD modeling based on conceptual sketches, and immersive virtual tours to evaluate user perception and design efficacy. Ad hoc questionnaires specifically designed for this research were employed. The results indicate a positive reception to IVR, emphasizing its ease of use, intuitive learning process, and effectiveness in improving motivation, academic performance, and student engagement during the conceptual design phase in graphic engineering education.
