Seeing, Deciding, Designing: Autoethnographic Reflections on Virtual Product Development

Unreal Engine, a real-time rendering platform developed by Epic Games, has expanded beyond gaming and is used in architecture, automotive design, and the movie industry. Due to its ability to generate high-fidelity visualizations, simulate real-world interactions, and support virtual prototyping, it also has the potential to be a valuable tool for industrial designers. This study investigates its application in product design through a self-reflective practice-based approach. As the sole participant, the author conducted iterative design experiments comparing conventional methods (sketching, CAD modeling, physical mock-ups) with Unreal Engine–based workflows in the design of handheld electronic gaming devices. The author’s reflections documented workflow efficiency, visualization quality, cost reduction, and learning experience. Findings suggest that Unreal Engine significantly improves iteration speed, offers highly realistic visualizations, reduces material costs by limiting the need for physical prototypes, and enhances design decision-making. The study demonstrates that Unreal Engine can transform industrial design practice by streamlining workflows, promoting sustainability, and fostering new competencies in digital prototyping.
