Efficient User Experience Design For Stock Trading Application

Nowadays,with the rapid development of mobile Internet,more and more investors trade stocks through mobile phones.There are many stock trading applications on the market,which have powerful functions and complicated contents.Precisely because of this,the operation of the software is very complicated and the user experience is uneven.User interface information overloaded lead to inefficiency.Only professional or experienced investors can use it skillfully,ordinary investors often feel confused about many candlestick charts and complex functions,unable to get the information they want in the first time.In the "experience economy" era,whether a good user experience usually determines the success or failure of a mobile app.Therefore,based on the user groups of stock trading,this paper focuses on the efficient user experience of stock trading APP.The main research contents as follows:APP design with good user experience needs to control the characteristics and needs of users.Starting from the users,this paper aims to identify the target group of stock trading is mainly male in developed cities aged 20-49,most of whom are retail investors.We questionnaires to target users to obtain more accurate user data,including user habits and expectations,to mine the needs of target groups in terms of operational efficiency and intuition.Then the crowd demand analysis is carried out in combination with the scene,and the user role model is established.Interaction paradigm is the basis of user interface design.Based on good paradigm is easier to create high-quality user experience interface.Therefore,we study and analyze the classical paradigms and metaphors in the field of human-computer interaction,inherit and improve the paradigm elements according to user's needs,and propose an interactive paradigm to improve the efficiency of use by emphasizing multi-window and component direct operation.This paradigm no longer overemphasizes gestures,and reduces the page Jump by emphasizing component direct operation reasonably.Operational level,emphasizing multi-window operation to improve user operation efficiency.Through the application analysis of the seven interaction laws,the five interaction principles of proximity,conciseness,intimacy,fault tolerance and habits are established.After putting forward the improved paradigm and establishing the principle of interaction,we use Axure 8.0 design software to design the wireframe of stock trading APP from six modules: quotation,trading,information,community,personal and message center.In addition to reducing the level of operation by reasonable layout and increasing component operation,the functions of fast transaction,breakpoint transaction and split-screen reading are designed to improve user operation efficiency.In the function design,the sequence diagram is drawn to show the function logic,and the database table structure is designed to define data fields and data types.Finally,we test the usability of the efficient stock trading APP based on the improved paradigm design.Analyzed the test user's task operation results and system usability scale(SUS)results.The test results show that the design of the software conforms to the user's operating habits and has a good user experience.By comparing with the operation level of popular stock trading APP,the advantages of this paper's APP in basic function operation efficiency are highlighted.At the same time,it indirectly illustrates that the improved paradigm emphasizes the effective application of multi-window and operation components in stock trading APP,so as to achieve the design purpose of efficient user experience design.
