Research On The Construction Of Human Adaptability Evaluation Model Based On AHP+PCA In The Interactive Interface Of Smart Phone APP

With the popularization and development of Internet technologies,smart phones have become an integral part of people's daily lives.The phenomenon that everyone has a mobile phones is everywhere.It becomes stronger and stronger that human beings are dependent on mobile phones,which leads to the competition in the APP market intensely.Nowadays,the function of the APP is more and more perfect,and users pay more attention to the emotional experience brought by the application.Therefore,the human engineering design of the interface is particularly important.An APP interface with good human engineering design and high suitability will receive high user evaluation.The APP,therefore,can quickly occupy the market.Or it will be replaced by the same function of the APP.Therefore,it is necessary to scientifically and reasonably evaluate the human habitability of the interface and increase the viscosity of users.This paper first summarizes the research background,research purpose and research significance of the dissertation,and summarizes the research status of human-engineering interactive interface design and smart phone interactive interface design at home and abroad,and thus has the overall idea of the paper,content framework and research methods.Secondly,the design criteria of the interactive interface are summed up,and the six factors affecting the human suitability of the interactive interface of the smart phone APP are obtained through the key event method,namely interface design,functionality,reliability,ease of use,feedback,and satisfaction.Sex,and then 28 measurable evaluation indicators are listed.After that by referring to the construction method of usability evaluation system,an evaluation system suitable for human interface suitability of the smart phone APP interactive interface is established,and the influencing factors are corresponded to the three dimensions of suitability indicators by one to one.At last a complete evaluation index system is constructed.Thirdly,a detailed analysis of the mathematical model and the calculation method of the analytic hierarchy process and the principal component analysis method is conducted.The advantages and disadvantages of the two methods are discovered.The subjective experience of the experts in the analytic hierarchy process is applied to the principal component analysis which makes up for the shortcomings of the fact that the principal component analysis ignores the realistic meaning represented by the data,and a new evaluation method is then built.Fourth,the improved evaluation model,which contains the evaluation index system and the improved evaluation method,is applied to We Chat.We evaluated the human suitability of the We Chat's interactive interface,and find that the interface has the human suitability problem and propose the corresponding suggestions for improvement.Finally,in order to make the above-mentioned evaluation process automately,the paper designs a human interface suitability evaluation system of the APP interactive interface,and analyzes the system in detail and the main functional design of the system.Through the above research,the following achievements have been obtained:the factors that influence the human suitability of the interactive interface of the smart phone APP,the corresponding evaluation system has been constructed,and the improved evaluation method has been applied to the We Chat,and the evaluation model has been verified effectively,find the inappropriate design of the interface,put forward the corresponding suggestions for improvement,and design the APP interactive interface human suitability evaluation system,which is conducive to the realization of the evaluation process proceduralization,and better optimization Interactive interface to improve the user's stickiness of the APP.
