Interactive design for cruise public spaces from the perspective of narrative in virtual scenes.

Cruising motivation is impacted by tourist experiences, and cruise companies exert considerable effort in constructing cruise travel experiences that could meet and ideally exceed passenger expectations. The public space of the cruise ship centered on the atrium is a nodal public space for cruise leisure experience and the climax of emotional experience. Spatial narrative design refers to triggering the empathy and continuous emotional experience of users, and it plays a significant role in the interior decoration design of cruise ships to strengthen the interest and appeal of the experience of space. With the development of interactive design technology, the spatial narrative is redesigned to support the exchange of information and stories that are transformed and transplanted into virtual and real environments. However, the existing research on interactive design mainly focuses on interactive multimedia technology and forms of expression, and there are few studies on the interaction between users and design solutions. Simultaneously, the existing research mainly expounds on the application of interactive technology in enhancing the narrative effect, but few studies explore the linkage relationship between interactive technology and spatial narrative theory. Therefore, this research takes the cruise's public space as the research object, deconstructs the narrative strategies and elements of the cruise ship public space interior design based on space narrative theory, and constructs a cruise's public space interactive design system based on Unreal Engine5 to collect users' design preferences. Furthermore, this research analyzes the linkage relationship between interactive design technology and narrative art of cruise public space design and further explores the interactive design mechanism of the cruise's public space under the narrative perspective. The results reveal that first, for space narrative design, the interior design of the cruise's public space constructs the narrative theme through the narrative elements of typical narrative images, symbolic styles, shapes, and colors. And the cruise's public space takes the atrium as the center and constructs the narrative grammar and unique spatial experience through the narrative sequence of beginning-development – climax-ending. Second, the interactive design system for cruise's public space is divided into three layers: bottom engine, data layer, and application layer. The underlying engine supports the construction of the cruise ship public space interaction design system through UE5's own character. The data layer contains imported 3D model data of the cruise's public space, material library, furniture library, and lighting special effect library. The application layer contains two parts: Virtual Roaming and Interactive Design. Third, the linkage relationship between the interactive design system and spatial narrative theory for cruise's public space could be concluded as follows: as a virtual space carrier of spatial narrative, the interactive design system can simulate the process of narrative practice through users' experience and interaction in virtual space. Simultaneously, users choose materials, furniture, and lighting effects in the interactive system and then feed back user preferences to designers in real-time to bridge the gap between designers' narrative design and users' narrative practice.
