| China has entered the era of e-government,and government platforms have been widely used in various fields such as urban construction,water affairs,agriculture,transportation,and ecological environment,playing a crucial role in fulfilling government responsibilities and ensuring the safety of people’s lives in various regions.With the continuous development of PC based government system technology,the demand for the platform is no longer limited to the efficient functional level,but begins to focus on the interactive,visual design,and other experiential requirements of the system.Visual fatigue syndrome refers to symptoms such as dry eyes,pain,and headache that occur when using a video display terminal for a long time.Mild visual fatigue does not seriously affect physical health,but as the work time continues to accumulate,it can lead to serious visual health problems and even mental health problems.Due to the prolonged use of data interfaces by operators of PC based government systems.there is an increasing number of people with visual fatigue syndrome in China.Therefore,how to improve the visual fatigue of operators in design and alleviate the adverse visual experience brought by the interface to operators during the use process is becoming increasingly important.In this context,from the perspective of interface color perception,this paper studies the physiological and psychological impact of interface color on target populations,and discusses the impact of data interface color on visual experience from the following four parts.Firstly,the symptoms,causes,and testing methods of visual fatigue in VDT are summarized;Study the type of color mode,obtain the color mode applicable to this study,namely HSB mode,further explain the theory of color quantification,and summarize the B-terminal interface color design elements;By analyzing the importance of color in interface design,exploring the relationship between interface color and visual fatigue,this paper proposes elements and principles of interface color design based on the theory of visual fatigue.Secondly,identify the target user group,and analyze the functions and business areas of the government system based on the market situation;According to the classification of application channels,select typical PC end government data interface cases,and analyze the characteristics and laws of case interface colors;According to the characteristics of existing government PC terminal interface fields,the interface content is classified and summarized into functional fields and content fields.A questionnaire survey was conducted to investigate the use and visual needs of operators,and based on interviews to investigate the visual experience of operators using PC based government data interfaces,identify design points that meet the requirements for alleviating visual fatigue,and establish the type of experimental samples.Thirdly,the physiological testing methods and psychological evaluation methods of visual fatigue are introduced into the research on the background color and theme color of the PC data interface,and the best color design scheme to improve visual fatigue is obtained through experimental data and subjective evaluation analysis.Finally,based on the design recommendations derived from the experimental analysis of color visual fatigue,carry out the design practice of"Smart Flood Prevention Big Data Display Platform",and establish a target user portrait through research on product positioning and user positioning;Analyze the functional requirements of the product,sort out the interface functional modules and information structure,design an interface prototype,apply color fatigue experimental conclusions on the basis of the interface prototype,build a PC terminal government data system to improve visual fatigue of operators,and conduct user evaluation tests to verify the feasibility of the conclusions.In summary,based on visual fatigue theory and testing methods,the relationship between interface color and operator vision is studied,and the visual needs of operators for PC end government data interfaces are investigated and analyzed.A color design method for PC end government data interfaces to improve visual fatigue symptoms is found to guide later design practices. |
