The purpose of this paper is to solve the problem of poor user experience caused by chaotic function, lack of humanization research in color, layout and interactive flow of the virtual monitoring system for fully mechanized coal mining face. Combining the situation design theory with the user experience hierarchy model, an interactive design method is proposed to construct the interface of virtual monitoring system in fully mechanized coal mining face. Firstly, this method completes the requirement definition and function analysis, and then prioritizes the system functions. Then, in the context solution process of “concept-prototype-vision” situation, interactive logic and visual elements are designed, and an efficient interactive design model is put forward. Finally, Unity3d development engine is used to develop the design scheme of the above virtual monitoring system.The fuzzy comprehensive evaluation method is adopted, and the experiment proves that the design scheme has a good user experience. The design method of system interface interaction in this paper is adopted to vertify that the design scheme has a good user experience through experiments, which also provides theoretical support for interaction design of virtual system interface.
