Based On The "Internet Plus" Campus Free Trading Platform Interface Design

The convenience of mobile devices makes it very convenient for users to use them,and mobile e-commerce has been developing rapidly.In the traditional electricity supplier industry when a red sea,the idea of sharing the economy led to the outbreak of idle goods trading model.In the university environment,the use of mobile applications is very high.While a college student in four years can produce more than 10 thousand yuan of idle assets(including computer,mobile phone,tablet computer,bicycle,clothing and daily necessities,etc.)which provides the soil for the growth of the campus idle transaction application.The purpose of this paper through the theoretical research on College Campus transaction application interface,formed a relatively complete set of methods,and guide the campus trading application interface design.The interface design of campus trading platform for college students is based on five levels of interactive design.Combined with the user mental model,Occam razor principle,micro interaction design theory and usability principle.According to the design content of different levels,the theoretical research is carried out,and the user mental model is combined with the user experience cognitive process,reference user's existing cognition to product positioning.According to the principle of Occam's razor,at the beginning of the product to avoid the system is too complex;from the trigger,rules,feedback,cycle four aspects of the micro interaction theory studied in detail,in order to facilitate the application in design.Nelson usability design principles,is used to form a complete set of interface design theory system.According to the theoretical analysis of the interface design of college students trading platform,the design practice is explored,that is,the interface design of campus free trading platform based on Android system(mainly for idle goods).The design process,the competitive analysis combined with user research,refine the demand,the demand for screening,combined with the principle of micro interactive design interface layer,usability evaluation,gives the final proposal.At the same time as the trading platform interface to the mobile device as the carrier,need to follow the design specification for mobile products.
