Research On The Design Of User-centered Fruit And Vegetable Cognitive Interaction System

The knowledge of fruits and vegetables is included in that of natural science.Hence,by learning this,children's ability of exploring and recognizing nature can be greatly improved.Putting fruit and vegetable knowledge together with mobile App can supply an interesting learning model and rich resources.As a designer,it can be founded that there are some issues in the existing Apps concentrating on such a field.,such as poor design of interface and excessive advertisements,which is extremely affects t users experience.On the other hand,many researches on interactive design of educational products focus more on children,while neglecting the parents who are always the one that teach the children to learn the products.Now we live in an experience-oriented world,so products design should follow usercentered Approach,ensuring that user's problems can be solved and ensuring that users enjoy the experience process while the problems are solved.While enjoying the convenience brought by the Internet,we worry about the impact.Since you can no stop change,adapt it.In order to alleviate parents' concern,we need to start from children,learning,emotion and experience to bring them more suitable and safe fruit and vegetable learning App.By studying the children group,parent users,interactions,design and other contents,the author actively exploits the advantages of electronic products and solves their shortcomings,providing children with a healthy and up-to-date educational products.What's more,it solves the problems of single knowledge of existing products,low aesthetic interface and inconformity with children's use psychology.At the same time,the methods and contents of the summary can be implemented in more children's products,providing a force for improving the market environment.The main research work of the thesis is as follows:1.Study the characteristics and needs of primary and secondary users of fruit and vegetable cognitive products.By using literature and observation methods to study the psychological development and behavior of children aged 3-6 years old,this paper obtains the characteristics of thinking,language,perception,creativity,game and use of the App under the psychological development of children in this age group.Conduct questionnaires and interviews to discover the secondary users'(parents)feedback on existing products and the needs of this application.2.Based on the user research content,we put forward the interaction design strategy of fruit and vegetable cognitive application,define the products' structure and process and complete,complete related competitive product analysis in the market and summarize the design goals.Based on the interaction design principle and user-centered design theory,we come up with the interaction design strategy of fruit and vegetable cognitive products under the development of children's psychology.Use the competitive product test and KANO model to analyze the knowledge of fruits and vegetables to improve the satisfaction of parents.Combined with the research on parents,this paper propose the interaction design strategy based on the parental goal of function to meet the requirements of children's development.Based on the user experience,an interactive design strategy is found out to improve the satisfaction of children's use experience.Combine the proposed interaction design strategy with the classification and structures of fruit and vegetable knowledge,to put forward the design principles of fruit and vegetable identification products.Use character modeling and scene analysis to define this product and design the knowledge structure of fruit and vegetable cognitive product task flow.3.Follow the interactive design strategy to design the fruit and vegetable cognitive product interaction systems and verify its availability.According to the goal-oriented interaction design process,this paper complete the verification of the interactive design strategy of fruit and vegetable cognitive products,and come up with the design of App hand-painted lowfidelity and high-fidelity interactive prototype,modeling and visual framework;and carry out interactive prototype usability test and verification.
