In recent years, with the rapid development of Internet technology, live streaming e-commerce has gradually become the focus of public attention and has occupied an increasingly important position in consumers' daily lives. The significant difference between online retail and offline retail is whether consumers can directly touch the products, and the perception of the products plays a key role in consumers' purchasing decisions. Therefore, how to display products effectively is crucial for online retailers. This study aims to explore how the product display method of live streaming e-commerce affects consumers' impulsive buying behaviour, and collect consumers' views on live streaming e-commerce through questionnaires. The results show that improving the vividness and interactivity of product displays significantly enhances virtual touch, which in turn promotes impulsive buying behaviour. However, there is a positive correlation between virtual touch and perceived risk, and perceived risk fails to significantly inhibit impulsive buying behaviour, but instead shows a positive correlation, that is, high perceived risk increases impulsive buying behaviour. The conclusions of this study provide new insights into the future interaction model between online retailers and consumers, promote two-way communication, and improve communication efficiency. Through this study, online retailers can provide consumers with an experience closer to offline shopping when using live streaming e-commerce, thereby more effectively prompting consumers to make purchasing decisions.
