The work aims to explore the application of scene interaction in the design of intelligent applications for hill climbing, to meet the physiological and psychological needs of hill climbing users, and improve the user's hill climbing experience. Firstly, based on the background of the current trend of intelligent application use under the current digital technology, the user survey and analysis were carried out in the objective scenario through the questionnaire method and the interview method; Secondly, the design elements in the target scene were stratified according to the three-level theory of emotional experience by combining the typical character model and the existing hill climbing application analysis, the AHP method was used to establish an analytic hierarchy process model in the actual scene, and the weight results of the design index were obtained. According to the weight results, the optimal design scheme of the intelligent application for hill climbing was obtained, and the design practice was carried out. The scene interaction design method is used to construct the design process, analyze the user needs and design indicators, and realize the interaction and integration between the hill climbing user and the intelligent application.
