The work aims to discuss the user experience pain points of public seats for waiting, and propose a public seat design scheme to optimize user waiting experience. Firstly, based on scenario thinking, the scenarios of passengers waiting for trains were analyzed, and the typical scenarios were extracted, and then the passenger behavior in the scenarios was analyzed to dig out the user pain points. By reconstructing the scenarios of passengers waiting for trains, the solution to passenger pain points during waiting was explored. Finally, the design was mapped to waiting seat design scheme in high speed railway station, to complete the innovative design of waiting seats in high speed railway stations, solve the problems encountered by passengers during waiting, effectively meet the practical needs of passengers, and create a good waiting experience for users. The introduction of scenario thinking into the design and analysis of waiting seats in high speed railway stations can help designers to analyze passengers' behavior more comprehensively, identify the existing problems of waiting seats, explore the potential needs of passengers, and then creatively propose solutions to guide the design of waiting seats in high speed railway stations. At the same time, the design method based on scenario thinking also provides a reference design approach for other products' innovative design.
