## 6 Conclusions and Future Work  
User demand emerges as a significant driver in the evolution of product design, playing a crucial role in shaping the direction of new product development. This study seeks to investigate several fundamental research questions: How can the Metaverse leverage to enhance interactive innovation in product development effectively? How can the requirements of diverse user groups in a Metaverse setting more seamlessly incorporate into the product development process? The interactive innovative product development model seeks to explore user-participatory design, fostering equal interaction amongst users, designers, and enterprises. However, interaction within the mobile Internet context typically exhibits complex attributes such as interactivity, self-organization, non-linearity, and scalability. Furthermore, interactive knowledge is often characterized by its vastness, dynamism, lack of structure, and disorderliness, posing challenges for enterprises in harnessing this innovative knowledge effectively. Additionally, the rapid pace of product turnover and the volatile nature of online public opinion contribute to dynamic customer preferences and opinions. Consequently, there is a need for an approach that can address such evolving demands. Moreover, mobile Internet interactive innovation tends to overlook certain user groups, resulting in products that do not fully align with user needs. The Metaverse, as a next-generation immersive Internet characterized by virtual identity, strong socialization, immersive experiences, and open content creation, offers a systematic technical foundation and comprehensive technological landscape, making it a promising solution for these challenges. Expanding upon this premise, this paper introduces an innovative framework for product development and design based on interactive innovation within the Metaverse. The framework is proposed after an in-depth analysis of product development and design, mobile Internet interactive innovation, and the Metaverse. Drawing on the Metaverse's capabilities, the framework establishes an interactive innovation product development mode encompassing the stages of \"_reality_\(\rightarrow\)_virtual_\(\rightarrow\)_reality_\". Leveraging Metaverse scenarios, this approach enables the meaningful participation of users at all levels throughout the product design process. Users engage in equitable interaction with designers and enterprises, collectively making decisions regarding product aesthetics. Moreover, it facilitates the seamless transformation of interactive innovation knowledge into design knowledge and enables real-time responsiveness to dynamically changing customer needs. Our research makes significant theoretical contributions and holds practical implications. Theoretical contributions include the development of a comprehensive framework t. The framework underscores the vital role of user engagement throughout all product development stages, filling gaps apparent in existing literature on user engagement. Additionally, by catering to the needs of various user groups, including extreme users, this study enhances our grasp of how specific needs impact broader user trends. From a practical standpoint, the proposed framework empowers organizations to address ever-evolving customer needs promptly, thereby reducing product development delays. Furthermore, by facilitating efficient user engagement and knowledge transfer, the framework aids in slashing product development costs. Engaging users in the design process can heighten user satisfaction, foster loyalty, and enhance market acceptance. In essence, this paper introduces a robust framework for integrating the Metaverse into product development, offering valuable theoretical insights and practical solutions to prevailing challenges in interactive innovation. The exploration of the Metaverse is an ongoing journey that is currently characterized by its youth and limited availability of pertinent research.
