Research On Usability Optimization Of Interface Information Display Of Coal Mine Monitoring System

The development of coal mine construction to digitalization and intelligentization promotes the comprehensive popularization of coal mine monitoring system which plays the role of source production safety management.The digitization of interface information display of coal mine monitoring system leads to the sharp increase of interface information,which increases the number of sub-tasks that monitoring personnel need to perform.The human error caused by this has become the main inducement for frequent coal mine accidents.Therefore,improving the usability of interface information display of coal mine monitoring system can provide decision-making information and technical support for coal mine production management and accident prevention at all levels.In this paper,the interface information display of coal mine monitoring system is taken as the research object,and the following research works are carried out around its usability optimization.Firstly,this paper takes the interface information display of coal mine monitoring system as the research object,analyzes the characteristics of the interface of coal mine monitoring system through field investigation,and compares the information display of the interface of traditional coal mine monitoring system and digital monitoring interface.Secondly,the basic concepts of visual search,the related theories of visual search and the basic modes of eye movement are elaborated in detail by using literature research method,and the eye movement indexes in interface evaluation are analyzed and summarized.Usability evaluation indexes and methods were summarized,all levels of indicators of usability were summarized,and the dimensions of usability were correlated with eye movement indexes.Total fixation time,fixation number and first fixation time were used to represent efficiency,thermal zone map and fixation trajectory were used to represent effectiveness,and pupil size was used to represent satisfaction.Next,combined with the field investigation of H coal mine monitoring system interface information display,the usability evaluation index system of interface information display was established.The usability influencing factors of the interface information display of H coal mine monitoring system were taken as the objects for evaluation.The optimized objects were selected through expert scoring and eye movement experiments were designed.The usability level of different types of interface information display was analyzed,and the experimental data and usability concept were combined to provide decision-making basis for the usability optimization of interface information display of H coal mine monitoring system.Finally,according to the experimental results,the improvement suggestions on the usability of interface information display in coal mine monitoring system are put forward,which provides an improvement idea for the optimization of the usability of interface information display in coal mine.
