With the development of live streaming technology, it has been applied to various industries, such as e-commerce and game streaming. The function of live barrage came into being, and its powerful linking ability greatly enhanced the interaction and participation of the audience. However, with the increase in the number of users, there is a phenomenon that the live broadcast bullet screen covers the video content too much, which affects the user’s viewing experience. Therefore, this study aims to explore how to combine people’s visual habits with the popup strategy of live barrage and adopt a more effective optimisation method to reduce the negative impact of excessive live barrage on users’ information acquisition. The study was successful through four main phases. Firstly, according to the characteristics of the live barrage, the relevant theories of previous studies are reviewed. Second, the existing research defects are identified in the current theoretical framework; third, while solving the present research defects, a program is implemented through coding technology for usability testing to verify the effectiveness of this optimisation strategy; fourth, the usability test demonstrates the effectiveness of the optimisation strategy. As an implication, this study further improves the optimisation strategy based on user feedback that could benefit viewers and live-streaming content providers.
