Integrating Rational Unified Process and Design Thinking Approach to Develop A Tangible User Interface for Mobile VR Immersive Scenarios Authoring Prototype

Virtual reality (VR) technology has advanced significantly in recent years. However, effective VR scene design remains challenging as it is both laborious and time-consuming. Although studies on immersive 3D scene editing have been conducted, it is currently limited to laboratory-specific designs or professional VR equipment. This study aims to develop immersive authoring systems that provide portability, accessibility, reusability, sustainability, cost-effectiveness, epidemic safety, mobility, immersion, and intuition not present in current commercial or lab-specific VR. To develop such a system, it is necessary to consider both the physical and software designs of the interaction, as VR-TUI is not only a computer device and software program but also a headset and an interactive physical controller. To satisfy the said research goal, the researchers of this study proposed an approach that integrates a rational unified process with design thinking to address the entire VR-TUI development and design. This approach can be used to develop human-centered products or systems that require integrating various software designs, hardware designs, physical designs, and other product or system design areas, providing an alternative reference development process and methodology for cross-disciplinary technology product development.
