Research On The Emotional Expression Of APP Interface In Digital Media Teaching

With the continuous development of mobile network technology, the third technological revolution-- the intelligence revolution that is based on Internet, biological engineering,artificial intelligence is quietly changing the world. The Intelligent phones as the current information transmission become the most widely convenient physical carrier, which promote the continuous expansion of the mobile Internet market, and mobile app is gradually influences people’s life deeply, foremost its own development and change also gradually formed the scale, especially the social class app is the most widely used mobile applications for social network which provides the maximum ductility. APP interface carries the function of visualization of the invisible logic language, as the most familiar visual public communication affects everyone’s life.The user interface design changed by the market driven and popular fashion variety, it developed from the initial stage of the digital semantic to the present most popular flat design style, experienced the reborn and reformed for many times, but from the beginning to the end it has never been out of the pursuit of emotional expression of intention. However, the convergence performance of the current interface technology design is very common, which is very unfavorable to the emotional needs of users. The theory of emotional expression is the birth of technology priority, lack of emotion, in the design of the emphasis and highlight the emotional impact of the performance is conducive to reverse the situation in the center of the situation, so as to establish the concept of UCD. At present, the role and work content of UI designers in the Internet design industry is gradually evolving, not only bear the part of visual design, but also deeply involved in the user research and interactive design. The reason is that the expression of the overall product design only rely on visual parts to complete the emotional is weak and pale, visual design must be established on the basis of human interaction design of a reliable which can really achieve the purpose of emotional expression,in the development process of the interface design of the entire project, the UI designer must participate in the design and the deeply analyze the function of the product and availability,not just from the instinct level, it must be based on instinct and behavior, reflect on the three levels of organic whole body basis, therefore, the research on emotional expression of interface design must understand the theory to support the method and practice of visual level,interactive level and user experience, in other words, the design practice must be as a whole.Therefore, the author believes that only on the basis of user experience design can reflect the emotional expression of the interface design. Its foundation must be the design of the interactive level, and harmony with the visual aspects of design, and reflective level design.This paper aims on APP interface in digital media teaching, based on the cognitive science and psychologist Donald Arthur Norman’s emotional design theory; try to explore App design in emotional expression way, on account of user as the core concept, in order to realize the emotional performance to digital media teaching App interface design.
