The superior features of the Metaverse make it particularly adapted to product design since it can fully satisfy the user with design solutions that can fulfil their emotional and functional imagination without any physical restrictions. However, its application in the design field has not been investigated since the interactivity that the Metaverse can provide has not been fully exploited. In this paper, an interactive design system facing the Metaverse is proposed to link Metaverse digital space and real physical space to enhance human-Metaverse interaction. The proposed system should be capable of integrating the design's physical content, including product components, with the designer's professional knowledge. For this purpose, the key to realizing this system, the product design process and its related design knowledge, has been modelled. The designer's professional knowledge is extracted and simulated as several perceptual cognition models. A fuzzy transformer method is innovatively developed for the perceptual cognition model's computational modeling. Using these models, the user-system-Metaverse interactions and virtual and real product interactions are enhanced. This work provides a conceptual framework for a Metaverse interactive design system based on human perceptual cognition computational modeling. The proposed system greatly extends the application of the Metaverse and it can be applied to various product design system developments.
