User Interface Design And Implementation Of Sticker Paradise System Based On IOS

With the rapid development of the mobile applications, the user experience and theusability of user interface become more and more important. The idea of User CenteredDesign has been seriously considered by the mobile application developers and the idea istaken as the effort to achieve a new success.Sticker Paradise System（SPS）is an iOS-based enlightening educational software forchildren’s drawing. But its earlier version has several shortcomings. Firstly, the user interfaceis too complex and difficult to understand, furthermore, the interactive task is toocumbersome and difficult for children. Secondly, as a game for children, the product functionof the education and the entertainment is insufficient, its game scene does not friendly to thechildren and the amazing effect is not strong enough.The article discusses the usability, design method and evaluation process of the UserInterface (UI) of mobile applications, and apply the method of User Centered Design (UCD)method to design the UI of the SPS and implement it later. By UCD, it can improve users’experience and satisfaction, thus enhancing the market competitiveness of this softwareproduct. Two kinds of requirement analysis methods are adopted, one is based on theprototype and the other is based on the model of the UI to analyze and evaluate the userinterface design of the earlier version of the SPS and the requirement analysis report isprovided. These researches focus on the navigation, the layout, the visual and interactivebehavior and the complexity of the UI. After that，the UI system’s design and implementationare discussed based on requirement analysis. The implementations of visual design,interaction design are presented in detail. Finally, some tests on the new SPS are carried outincluding the tests of the system functions and the user experience. The results of the testsshow that the UI system has good user experience and usability.
