Research On Preschool Children's Habit Forming Product Design Based On Reinforcement Theory

This paper is based on Reinforcement theory,using the UCD method(UCD: User centered design),approaching the agile software development process(Agile),taking the brushing habits to develop mobile applications(Mita dental care,)for example,for preschool children used product design.Through the app store's competing products research,it is found that the widespread user demand for positioning is not clear,parent-child interaction is in lack of,child behavior and incentive mechanism is not scientific,practicability is not strong.Through literature analysis,research at home and abroad mainly have the following problems:1)The lack of theory of strengthening pre-school children's habits based on APP design method: at present mostly are scattered design principles and considerations,in lack of specific design steps and process guidance;2)Few researches are on the advantages of mobile situation,such as: the lack of research on the virtual scene and virtual reinforcement,the lack of research on the O2 O model,etc.;Therefore,UCD method is used,based on the theory of strengthening the Mita Dr.App,to carry out research and practice,expand the analysis,design,rapid prototyping and usability evaluation:Firstly,use the secondary data analysis,graphical questionnaires,behavioral observation and user interview method research of the user demand,to build a needs analysis model with user profiling method;the system participants,objectives,functions and the basic constraint conditions are identified.Secondly,based on the use case description,the concept design of App is carried out:1)Considering 21 days for the best behavior habit forming cycle,determine the target of brushing teeth.2)During the information architecture design,introduce the standard andteeth-missing brushing mode,divided into day and cycle forms,with the calendar in the form of records,statistical characteristic analysis of brushing and behavior.3)In interaction design,basing on reinforcement theory reinforcement and secondary token system design of toothbrushing behaviour of the incentive mechanism,the behavior scenes of the virtual and real scene strengthen the scene are put forward;4)In visual design,base on the strengthen theory of "ritual" and platform design guiding to finish the interface design,base on Axure rapid prototyping tool to design the dynamic interactive prototype and for development and delivery;After software development,base on prototyping and modelling methods to conduct usability evaluation;use GOMS model method to test the system availability,getting the task time,accuracy and user satisfaction data.The results of data analysis and the discussion are used to improve the page.Through the verification of design practice,the results of this study can effectively guide preschool children used products design,providing guidance for the future design of similar products,and the innovation and practicability are very important.
