Research On Flat Design Application In APP User Interface

Along with the constant improvement and updating of information technology,smart phones enjoy a more and more popular position in the market,and the number of people using mobile clients has risen dramatically.Via a variety of APPS,people can shop,watch movies,and read literature.From this perspective,people are affected by the APP client everywhere.Therefore,the development of the APP is undoubtedly the mainstream of the development of mobile Internet.Starting from the historical evolution of the user interface of APP,this paper develops into a realistic and practical style from the initially simple,roughed and emotionless.Finally,by 2013,Apple had made a disruptive revamp of systematic interface of IOS7.Designers generally acknowledge that the flattened interface is not only a current trend of the times,but also a trend of development.The study of flattened design style is the need for the development of the information age,because this style discards the tediously decorative effect.Exploring the design language of flattened visual communication,advocating simple graphics,bright colors,clear layout and so on these characteristics are very suitable for this large amount of information,complex content of the user interface of APP.As time goes by,it is found that an interface that is too flat makes people feel truly stiff,that the graphics are too abstract,and that there are no well interactive hints.In an effort to shift this malpractice,and produce a newly flattened style,it can endow with micro-projection,micro-gradient and other visual effects,which enables the content of the picture clear,and the operation simplify.This paper pays attention to the characteristics and principles of flattened style.Through the questionnaire survey,this paper further analyzes the effect of the newly flattening,as well as discusses the significance of flattening to the user interface of APP.On the basis of these theories,this paper combines the design and practice of the flattened user interface of the graduation design "Shi Guang"APP,so that this paper is done in combining the theory and practice.Through further research and demonstration,this paper concludes that in the field of vision in the user interface of flattened APP,designers should follow the characteristics and principles of flattening and innovate boldly in the interface design.Survey only to analyze the users' use and purchase orientation,can design a high-quality user interface of APP,and effectively improve the users' experience,and enable the process of using and downloading facilitate for users.
