Design And Implement Of Human Suitability Test Program For Smartphone App's Interface

Diversification of APP to meet users needs,and bring convenience to the user,at the same time,its also exacerbated the APP market competition.An APP market retention rate depends not only on the functional requirement sand its convenience of processing,more critical is the user's feeling.To make a good user experience,the interface of APP is in dispensable to meet the design of human factor engineering.If APP user interface is designed with a good human engineering actively,APP market retention rate will be high.Contrarily,If APP user interface's design does not pay attention to human engineering design and the user is affected negatively,APP market retention rate will below,or even eliminated by the market.Therefore,APP market urgently need a procedure to test whether the user interface is suitable to human.The test program is designed to automate the testing process,reduce the resource consumption during the test process,avoid a large number of user surveys in the test content,and improve the efficiency of the APP user interface for suitability testing.Based on the relevant design principles,this paper designs the overall structure of the test program so that the test flow is clearly presented from the data input layer,the data analysis and matching layer,and the output layer.Using the SQL structured query language to access the user experience data,thus establishing the APP user interface human adaptive database.Through the MATLAB software graphical user interface design tool GUIDE design APP user interface for the suitability of the test program graphical user interface GUI.Finally,select the appropriate technical model,designed eye movement experiment,and established eye movement measurement parameters versus user experience subjective evaluation of the linear relationship,based on this model to MATLAB as the carrier design APP user interface human suitability test program.This article uses the V6.5.5 We Chat APP user interface with their solution of 1136*640 pixels on the iphone5 s,and designs the user experience questionnaire according to the user interface operation task.The user experience data is processed with the Likert scale and stored in SQL with hierarchical structure.According to the user interface operation task,eye movement experiment is designed.The measured parameters(operating time,task completion rate,error rate,the total number of points)are input value in test program.The user experience data is obtained through the MATLAB callback function which connect SQL.It can quickly and efficiently detect the existence of human engineering problems in APP interface,avoid a large number of interviews and improve efficiency to test the APP user interface's suitability.
