Research On APP Interface Design Under User Emotional Experience

"Most people will forget what you said and what you did,but they will never forget how you made them feel."Today,when we think about the products we want to use,we have many choices.But one thing has an unparalleled place in the decision-making process: emotion.We evaluate products not only on the basis of practicality,but also on the basis of the feelings they evoke.We prefer to choose products that can produce exciting results rather than boring products that can only solve our problems.This is emotional design.Emotional design has always been at the top of user experience and demand pyramid.After solving the problem of product functionality and usability,more and more designers pay attention to emotional design.Emotional design can be divided into narrow sense and broad sense.In a narrow sense,it is a design that can bring hard work,positive and positive emotions to users,such as happiness,self-confidence,optimism and appreciation.In a broad sense,it includes not only the positive emotions,but also the negative emotions,such as anxiety,sadness and depression.To judge whether the emotional design of an application is excellent or not,it depends on whether it can effectively help this application stand out in the market competition of the same type of application.An application with excellent emotional design can let users actively promote it,and improve users' loyalty and identity to the application.This paper systematically combs the emotional design and the theoretical overview of mobile app interface design,and comprehensively studies the influence of various emotional factors on mobile app interface design.Finally,the three-level emotional design theory proposed by Donald A.Norman is perfectly integrated into the interface design of alarm clock app,which makes the interface design of mobile app fully integrate emotional design.At the same time,the source of user's emotion and user group's usage habits are studied,and the alarm app interface is further studied and analyzed.And implement the core design principle of "user centered" in practice,in order to achieve the goal that users can get a better feeling and experience when using the application.
