## 5 Discussion  
Since product development in the Metaverse occurs within a virtual environment and involves spontaneous customer and stakeholder interaction, the process is nearly cost-free. Additionally, thanks to the Metaverse's lack of spatial and temporal limitations and the high efficiency of its virtual platform, the development cycle can be significantly shortened. All user groups can actively participate in real-time design, development, and decision-making evaluations, resulting in products that align more closely with user needs.  
Therefore, the Metaverse-enabled interactive innovation for product development and design not only surpasses the constraints of mobile Internet interactive innovation but also offers numerous advantages. Firstly, the Metaverse transcends barriers such as time, space, race, and language, supporting language recognition and accurate communication comprehension among users and systems. Users can express their thoughts through virtual avatars, enabling 24 h real-time activities within the interactive innovation realm of the Metaverse. This fosters anytime interactive communication and innovative ideation, ultimately enhancing development efficiency. Secondly, the Metaverse provides diverse creation platforms and social scenes, enabling profound and equitable interaction across user groups, designer groups, and enterprise departments. Moreover, interactive innovation knowledge can be seamlessly transformed into design knowledge, enabling real-time responses to the ever-changing dynamic customer needs. Thirdly, the Metaverse's interactive technology offers users an immersive virtual reality experience, allowing them to fully and realistically explore products within the virtual space. The product development process is highly flexible, empowering users, designers, and enterprises to make modifications and optimize designs at any time, significantly reducing development costs. Ultimately, through evaluation and decision making, products align better with users' diverse and individualized needs while meeting the production plans of enterprises. This ensures a win-win situation where user requirements are satisfied and enterprise reputation is enhanced.  
However, there are some potential risks associated with the implementation of the model such as technology dependency and cost, data security and privacy, user experience, collaboration and communication, innovative knowledge management, system stability and reliability. These risks can manifest in various ways. Firstly, the development and maintenance of the Metaverse platform, as well as the related AI and big data analytics software, require significant investment. Secondly, there are risks of data leakage and misuse of user data, design data, and intellectual property information in the virtual space. Thirdly, discrepancies between the virtual environment experience and real-life usage may occur, leading to virtual test results that do not fully mirror the actual situation. Additionally, diverse backgrounds and expertise within different groups can create communication and collaboration barriers, affecting project progress. The efficient filtering and management of a large volume of user ideas and feedback are crucial to prevent information overload and decision-making challenges. Moreover, a stable network connection is essential for effective virtual collaboration, and network issues can result in work interruptions and data loss.
