Multimodal interaction design of HMI for electric vehicles in China: A study to enhance user experience

Under the current severe challenges of global climate change and environmental pollution, the rapid development of electric vehicles (EVs) is seen as a key way to achieve sustainable development in the transport sector. EVs not only reduce dependence on fossil fuels and lower greenhouse gas emissions but also bring a new driving experience to users through their advanced technological features. In this transformation process, human-machine interaction (HMI) design plays a crucial role, which directly affects user acceptance and satisfaction with EVs. This study thoroughly analyses the application of multimodal interaction technology in HMI design for EVs, which greatly enriches the user interaction experience by integrating multi-sensory information such as visual, auditory, and tactile senses. We paid special attention to how the multimodal interaction design can enhance user convenience and driving safety, and how it can satisfy the needs of different users through personalized interaction. Through quantitative research methods, we used SPSS software to analyze the experimental data in detail to assess the effectiveness of multimodal interaction design in practical applications. The experimental results reveal the significant advantages of multimodal interaction design in enhancing user experience. Compared with traditional interaction methods, multimodal interaction design not only shortens the time for users to complete tasks and reduces the operation error rate, but also achieves a significant improvement in user satisfaction. These results suggest that multimodal interaction design can provide users with a more intuitive, natural, and enjoyable interaction experience, which is crucial for promoting the popularity of electric vehicles. In addition, the findings of this study provide valuable insights for the future development of HMI design for EVs. With the continuous advancement of technology and the increasing diversity of user needs, future HMI design needs to pay more attention to user-centered design principles and take full advantage of multimodal interaction technologies in order to create a smarter and more personalized driving experience.
