Research On Visual Design Guideline Of APP User Interface In Fragmentation Age

The rapid leap of digital technology and the vigorous popularization of mobile devices not only overturn the traditional Internet interaction,but also accelerate the formation of the fragmentation era.The frequent update of information makes the amount of information in the present era increasing,even increasing in exponential form,people learn a large number of fragments of information through the Internet every day compared with the past.Against this background,users are eager to find out the key message more directly and clearly that the interface wants to convey,and quickly filter out the information they want in the face of the large amount of content displayed in the mobile software interface.However,in view of the fragmentation era,the research on the visual design method of user interface is missing.This subject starts with the needs of the users under the influence of the times,and explore the guidelines of visual design on user interfaces in the era of fragmentation.Based on the in-depth analysis of the user needs in the fragmented era,this paper studies the sensory features in the interaction between the user and the mobile phone interface,and it is found that vision still dominates under the condition of existing technology.Then this paper uses TRIZ theory to analyze the user interface of two representative mobile phone software at home and abroad,to understand the development and change of interface design style in different times,and to predict the development trend of design style in current era.And then starts from the root of people's understanding of things,study the influence of light and color on user perception,and the theories and laws related to interface visual design in interactive design.On the basis of this,cognitive psychology is regarded as the focus of research,and the information processing system of human brain is taken as the starting point to study the user's processing of stimuli,and also analyzes the factors that affect the user's attention and cognition,and probes into the psychological and behavioral rules of the users when facing an interface.Color,navigation,icons,copywriting and graphics are essential elements for the visual design of any mobile software interface.In order to design a high-quality visual interface with good user experience,the most important thing is how to design and arrange the distribution of elements reasonably.The visual design process of the interface has no obvious logical relationship,but there are rules to follow.Therefore,this paper puts forward several design principles after the previous analysis.Based on the characteristics of the times and the needs of the users,the design principles and methods summarized from the users' external perception and cognitive psychology can give users a more intuitive visual experience,effectively guide the users and enhance the user's identity,and then meet the needs of today's fragmentation era.
