Research Of Interaction Design On User’s Privacy Message Protection

With the improvement of the function of smart phones,mobile phones have become an indispensable part of people’s life.A large amount of information stored in mobile phones,people use them to communicate,store files,pay bills,and entertain.People enjoy its convenience as well as face the crisis of privacy.Nowadays,privacy issues are gradually taken seriously.But research on preventing privacy information from disclosure mainly focused on the aspect of computer technic,few on the aspect of interaction design,so Apps to protect privacy information in mobile phone can’t meet user’s requirements.The paper uses user-centered design method as theoretical basis.Firstly,the paper studied relative theory on user privacy,and had a contrastive analysis on existing privacy protection Apps.On this basis,after using questionnaire to do user investigate,the paper used SPSS statistics software to analyze the result.Then,the current situation of user privacy protection and the privacy protection content were got through descriptive analysis method,4 user concerned elements were contracted through factor analysis method,thus to obtain the user privacy protection model.According to the user model,design requirement definition was concluded by using goal-directed design method.Combined with the interaction design principle,the paper summarized a design principle on user privacy protection,which guided the interaction design of the privacy message protection App called "Mystery",that utilizes existing forms of interaction as well as explores new ones comprehensively,and chooses interactive gestures properly.Lastly,the App incorporate story information elements into visual design,assisting the interaction design,to make the App easy to operate and understand,which can meet the demand of user privacy protection.In the process of design assessment,the paper put user needs into typical story usage scenarios,in order to validate the APP’s function and framework,and then put forward improvement scheme.Finally,it translated the user research results into a usability evaluation model,through a contrast test,to verify the availability of "Mystery" App.
