Ergonomics Research Of Different Visual Alarm Forms On The Digital Interface

Among the information presented on the digital interface,alarm information is particularly important.If the alarm information cannot be handled correctly and efficiently,serious consequences will result.In order to give full play to the ergonomics of the information systems,reduce the cognitive friction between users and digital interfaces,and establish a better human-computer cognitive matching relationship,this paper analyzes the research status of digital interface visual information presentation,visual information coding cognition and its application,along with visual alarm information performance measurement.And then,this paper integrates the information processing theory,the user cognitive characteristics analysis,and the cognitive psychology,combining ergonomics research methods such as interface performance measurement experimental research,and eye-tracking experiment,based on user visual cognition of the alarm information,conducts an ergonomic study of different visual alarm forms on the digital interface.The main research works were as follows.Firstly,by introducing the basic research of ergonomics,this paper summarizes the ergonomics research methods applicable to different application background.Combining with the information processing theory,it summarizes the attributes of alarm information and discusses the cognitive flow of digital interface alarm information,and analyzes the user's visual coding cognitive characteristics and design requirements from color,figure,flash,size,characters,and proposes corresponding coding principles.Secondly,according to the specific interface background,a number of visual alarm forms for radar interface are designed,and the performance of alarm information identification performance under different visual coding forms is carried out.Through the accuracy rate and response time index,this paper gets the optimal alarm type of visual recognition performance under single dimensional and multi-dimensional coding.Through the comparison and analysis of the performance data of the single dimensional and multidimensional visual coding,the influence of the encoding form on the improvement of the alarm information transmission performance is summarized,which provides a design basis and reference for experimental support for the display format of digital dynamic interface alarm information.Finally,by conducting the digital interface eye-tracking assessment experiment,the eye movement evaluation index(browse trajectory,average gaze point,average fixation time,average pupil diameter)of the digital interface visual alarm is obtained,and the eye movement performance evaluation of the visual alarm in the digital interface is completed.This paper validates the validity of the conclusions of behavioral experiments from the physiological aspect of eye movements and provides theoretical support and physiological assessment techniques for the research of “information coding—user visual cognition”.
