Introduction In today's digital age, UI design has become one of the key factors for the success of products or services [1]. UI design is not only related to the appearance and feeling of products, but also how to guide users, meet their needs and improve their participation [2]. In recent years, with the rapid development of artificial intelligence technology, NLP, as a key human-computer interaction technology, has been widely used in UI design to provide more convenient and personalized user experience [3]. NLP is an artificial intelligence technology, which is used to communicate between people and computers [4]. Early NLP technology was mainly used in word processing and language translation. With the continuous development of technology, NLP has been applied to the field of UI design [5]. For example, applications such as chat bots, intelligent customer service and adaptive navigation are all UI designs based on NLP technology [6]. These applications can understand users' language input and provide personalized feedback and suggestions accordingly, making it easier for users to complete specific tasks or obtain needed information [7]. At present, NLP-driven UI design is widely used in various fields. However, there are also some problems. First of all, the development of NLP technology also faces challenges such as word sense disambiguation and sentiment analysis [8]. Secondly, the application of NLP technology needs a lot of data and computing power, which is a difficult problem for some applications with limited resources. In addition, the application of NLP technology often requires interdisciplinary cooperation, which increases the difficulty and cost of development. This paper aims to explore the influence of NLP-driven UI design on user participation, so as to provide valuable reference for related research and application. This paper discusses the NLP-driven UI design by combining literature review and case analysis. First of all, through combing and evaluating the relevant literature, we can understand the advantages and disadvantages of NLP-driven UI design in improving user participation. Then, combined with practical cases, the NLP-driven UI design is deeply analyzed to reveal its influence on user engagement and its mechanism. Through research and analysis, this paper finds that NLP-driven UI design has obvious advantages in improving user participation. 2. NLP and UI design 2.1. Application of NLP in UI design NLP is an artificial intelligence technology, which is used to convert natural language into computer-understandable language. In UI design, the application of NLP technology can help users to interact with computers more conveniently, thus improving user participation. NLP is defined as a technology that transforms human language into computer language [9]. The main techniques include part-of-speech tagging, syntactic analysis, semantic understanding and machine translation. The application of NLP in UI design is shown in Table 1. NLP can be used in UI design in the following ways: ① Natural language interactive interface: This means that users can interact with computers through natural language. For example, users can speak their own needs directly to the computer, and the computer can convert the user's voice into text through NLP technology, and then respond according to the text content [10]. This way of interaction provides convenience for users, without learning a specific computer language. ② Speech recognition technology: This is a technology that enables computers to understand and use human language. At present, intelligent voice assistants (Siri, Xiaodu, etc.) are widely used. When users give instructions to such tools, they convert these voices into words through speech recognition technology, and then respond through preset algorithms. ③ Text analysis technology: This refers to the analysis of text by NLP technology. For example, we can understand the content and emotion of the text input by 64 users through text analysis, so as to make more accurate service recommendation. Table 1. Application of NLP in UI design Application mode Describe Speech recognition technology Voice interaction between human and computer can be realized by converting human voice into text information that can be recognized by computer. Text understanding and analysis technology By analyzing the text input by the user, the key information is extracted to realize the understanding of the user's intention. Machine translation technology Through NLP technology, the text in one language can be automatically translated into another language to break the language barrier. Text generation and dialogue system technology Through NLP technology, user-readable text content is generated, and functions such as text generation and dialogue are realized. Emotional analysis technology Analyze and judge the emotions expressed in the text through NLP technology. Entity recognition and relationship extraction technology Through NLP technology, the entities and relationships in the text are identified, and information extraction and knowledge map construction are realized. Semantic web technology Through NLP technology, the text is transformed into semantic form, and semantic web construction and intelligent reasoning are realized. Man-machine cooperation technology Through NLP technology, human-computer collaborative interaction can be realized, and the efficiency and experience of human-computer interaction can be improved. 2.2. Improve user participation First of all, the application of NLP technology improves the usability of the interface, so that users can interact with the computer without learning a specific computer language, thus reducing the difficulty of use and improving the user's participation. Secondly, the text information and emotions extracted by NLP technology can better help to understand users' needs and preferences, and make personalized service recommendations, thus improving the user experience and further improving user participation. Finally, due to the continuous development of NLP technology, the "understanding" ability of machines is getting stronger and stronger. It is conceivable that in the near future, the interaction between users and machines will be more convenient and in-depth, and the user participation will be improved to a greater extent. 3. Importance of user engagement User participation usually refers to the degree of user's investment in the process of using products or services, including cognition, emotion, behavior and time. It reflects the user's interest, concern and investment in products or services, and is an important indicator of user experience and satisfaction. The importance of user participation is mainly reflected in the following aspects: ① Improving user satisfaction: products or services with high user participation can usually better meet users' needs and expectations, thus improving user satisfaction. When users are interested in products or services, pay attention to them and put in time and energy, they are more likely to feel satisfied and happy, and then have a good evaluation of products or services. ② Improve user loyalty: Products or services with high user participation can often cultivate user loyalty. When users have trust and dependence on products or services, they are more likely to become long-term users and are willing to continue to use and recommend the products or services. This kind of user loyalty is of great significance to the long-term development and competition of enterprises. ③ Promote user behavior: Products or services with high user participation can stimulate users' positive behavior. For example, users with high participation are more likely to conduct positive behaviors such as word-of-mouth communication, sharing experience and recommending others, thus providing strong support for the promotion and development of products or services. In order to improve user participation, designers need to consider how to attract users' attention, stimulate users' interests and emotions, and guide users to conduct positive behaviors in UI design. For example, we can design a more attractive and practical interface by studying the psychological needs and behavior habits of users; Through NLP technology, we can provide more intimate and personalized services and improve users' satisfaction and loyalty; Through data analysis, we can find the pain points and needs of users, and then improve products or services and increase user participation. 4. Influence of NLP-driven UI design on user engagement With the continuous development of technology, NLP technology has been gradually integrated into UI design to provide users with more convenient and intelligent services. This kind of UI design with NLP can further improve user participation, thus increasing user stickiness and improving the use value and market competitiveness of products or services. The direct and indirect effects of NLP-driven UI design on user engagement are shown in Table 2 and Table 3. 65 Table 2. The direct impact of NLP-driven UI design on user engagement Influence aspect Describe Difficulty of use By transforming the user's natural language input into a language that can be understood by the computer, the difficulty of use is reduced and the user's participation is improved. User Experience By understanding users' intentions and emotions, we can provide more personalized services, enhance user experience, and then improve user participation. Interactive efficiency By realizing the functions of text generation and dialogue system, the interaction efficiency is improved and the user participation is further improved. Table 3. Indirect influence of NLP-driven UI design on user engagement Influence aspect Describe User loyalty By improving user satisfaction and providing personalized service, we can cultivate user loyalty, and then improve user participation. User behavior Through NLP technology, intelligent recommendation and other functions can stimulate users' positive behavior and improve users' participation. Product promotion and development Through NLP technology, we can improve the user interface and interaction mode, improve the quality and market competitiveness of products or services, and then promote user participation. Specifically, its impact on user engagement is as follows: NLP technology can enhance the adaptability of user interface. Traditional user interface requires users to learn a specific computer language to operate, which undoubtedly increases the difficulty for users to use. NLP technology can transform the user's natural language input into a language that the computer can understand, so that users can interact with the computer without learning a specific computer language, which reduces the difficulty of use and improves the user's participation. At the same time, by analyzing the user's language and behavior, the interface can automatically adjust its layout, function and interaction mode to adapt to different user needs and preferences. This adaptive UI design can reduce the user's learning cost, improve the convenience and efficiency of operation, and thus promote the user's participation. NLP technology can improve the feedback and response of user interface. Through NLP technology, the user interface can better understand the user's operation intention and provide more accurate and personalized feedback and response. This kind of intelligent feedback and response can enhance users' trust and dependence on products or services, and further improve users' participation. NLP technology can also realize the personalization of user interface. By analyzing the text input by users through NLP technology, users' intentions and emotions can be extracted, so as to better understand users' needs and preferences. This personalized service recommendation can enhance users' sense of participation and improve users' satisfaction and loyalty. For example, a shopping application can analyze users' comments and chat records through NLP technology, thus recommending products that are more in line with users' needs and preferences, and improving users' shopping experience and participation. NLP technology can realize the functions of text generation and dialogue system, thus further enriching the user interface and interaction mode. For example, an intelligent customer service system can automatically answer users' questions through NLP technology, or help users solve problems through intelligent recommendation and other functions to improve users' satisfaction and participation. NLP technology can also extend and update the user interface. Through NLP technology, the user interface can be expanded and updated according to users' feedback and needs, so as to continuously optimize and improve products or services. This extensibility and renewability can maintain the competitiveness of products or services, attract more users to participate, and improve users' loyalty. To sum up, NLP-driven UI design has many influences on user engagement. Through the application of NLP technology, the adaptability of user interface can be enhanced, the feedback and response of user interface can be improved, the user interface can be personalized, and the user interface can be expanded and updated, thus further improving user participation and improving the quality and market competitiveness of products or services. Therefore, designers need to fully consider the application of NLP technology in UI design to meet the needs and expectations of users. 5. Conclusions This paper discusses the NLP-driven UI design and analyzes its influence on user participation. It is found that NLP-driven UI design has obvious advantages in improving user participation. NLP technology can reduce the difficulty of users, provide more personalized services, realize functions such as text generation and dialogue system, and further improve user participation. At the same time, different scenarios need to flexibly adjust the UI design to meet different user needs and preferences. With the continuous progress of technology, NLP-driven UI design will become the mainstream of UI design in the future, but there are also some problems. In order to give full play to the advantages of NLP technology and solve the existing problems, the future research can be carried out from the following aspects: ① optimize NLP technology to improve its accuracy and robustness; ② Study the NLP-driven UI design pattern suitable for different fields and scenarios; ③ Explore how to combine NLP technology with other interactive ways to provide a richer and more efficient interactive experience; ④ Customize NLP-driven UI design for different user groups and needs. 66 References [1] Chen Shuting, Shi Shengbo, Yang Xiaobo.
