User-Centric VR-Based Single-Family House Interior Design System

Yuxuan Zhang
The vital role of interior design is gradually being realized due to its frequent interaction with the occupant and significant influence on building performance regarding living experience and indoor environmental effects. However, the current practice of interior design is inefficient and usually fails to satisfy occupant expectations, given that a universal data management process has yet to be established in the interior design industry that is comparable to those of other fields of

However, communication failure is common among occupants and designers, regarding the actual requirements, preferences, and design concepts of home design, due to their diverse levels of understanding and expertise. Therefore, this research proposes a virtual reality and building information modelling (VR-BIM)-based interior design framework aiming to incorporate BIM into the interior design profession and implement UCD more efficiently and effectively. A prototype system is also developed to enable data communication between the BIM software and VR platform as well as verify the proposed methodology. In this research, the tasks of interior finish material selection and lighting design are studied and improved with the introduction of two novel approaches. These two approaches function as the "brain" of the system to assist the user in making better design decisions based on the embedded rules acquired from design guides and previous research. Also, several multi-criteria decision-making methods and an optimization algorithm are implemented to facilitate the rule-application process. The results from case studies conducted in this research indicate that the proposed framework can improve the data management of interior design, and it is capable of assisting the user in designing a living iii environment that is based on their actual requirements without the need of any significant experience or background in interior design. iv ACKNOWLEDGMENTS First and foremost, I would like to express my sincere gratitude to my supervisor, Dr. Mohamed Al-Hussein, for his constant support, inspiration, and guidance throughout my M.Sc. study. It is a great honor to be his student. With his mentorship, I have a new and valuable understanding regarding my future career path and how to become a professional researcher. Also, it has been a great privilege to work around many exceptional colleagues and friends for the last two years:
