Research on interaction design based on user experience

李晓

【Abstract】： interaction designers to create products and services are useful and practical for the purpose of user centered design as the basic principle， the actual operation must be based on the actual user understanding： including their goals， tasks， experience and needs etc.. User centric perspective， while trying to balance the user needs， business development goals and the relationship between the level of scientific and technological development， the definition and development of new interactive products and services.

【Key words】： user experience; interactive design; psychology;

The interactive design stages based on user scenarios， including "what place， what time， what， what do things， how to finish this thing further may also need to understand" why do you need to do this thing. In the "Scene" in "what people， what time， what place， what is done" is to do the premise of interaction and background knowledge， the need to give priority to answer， you can get through the user research. In the "Scene" in the "how to complete this thing" is the essence of interactive design need to design the end result. Specifically including： user behavior process （flow chart， etc.）， behavior mode （interaction method， etc.）， behavior feedback （interaction effect and so on） and so on several aspects. Where the process is the basis of the interaction designer needs to sort out the user action process， in order to meet the user convenient， efficient and even interesting to complete a behavioral goal.

Interaction design： Based on advanced stage stage is completed for the design goal can be used， easy to use "， to ensure that users can complete their" task "in the process of smooth and efficient， without interference". That how to allow users to achieve the "want to use" the level？ Need to further focus on the point also includes user psychology". The essence of the user experience， I personally think that is for the "people" and targeted "optimization design"， where the "person" is more refers to the user's psychological and perceptual experience. "User psychology"， which corresponds to the "user needs" from the macro level， corresponding to the "mental model"". Macro on the "user needs" is the premise of product design， only to meet the needs of users of a certain product will be accepted by the user so as to achieve the "want to use" level. The "mental model" is the interactive design of the starting point and the end users understand the "mental model"， in order to better understand user behavior and target optimization process， enhance the user experience， achieve the design goal of "want to use".

An interactive designer to create useful and practical products and services for the purpose of. User centered design as the basic principle， the actual operation of interactive design must be based on the understanding of the actual user： including their goals， tasks， experience， needs and so on. The user centered perspective， and try to balance the relationship between user requirements and business development goals and development level of science and technology， interaction designers provide solutions for complex design challenges， definition and development of new products and services and interaction.

We live in the most real products and tools， because after dozens of hundreds or even thousands of years evolution， no matter form （user visual and touch） or use mode （user mode）， has formed a strong relationship mapping in people's heart （mental model）， namely the user see， you know what tools （physical interface）， you know how to use this tool， as long as the design meets a certain specification. Go back to the interaction design of information system， electronic information system was born just a few decades， this is a kind of unprecedented new tool mode -- the information mapping the real world to the information system， and through the mapping out of the information to understand the real world， is presenting information with people the second mapping. Later， simply some of the information and the reality of the world's mapping has become very weak even without contact （such as social networking， some games）. People need to learn how to understand and manipulate virtual objects （information） in an information system （virtual world）， like real things in the real world. Because this product is born in short time， and no product evolution to a human being recognized， consensus （modified model design of virtual information and the cost is relatively low， resulting in more complex form）， and the evolution of the human brain is basically still in use of primitive tools， roots are not evolved to with a large number of virtual information， so， in order to use the information tools that most people can minimize obstacles， must make the design of these information tools in accordance with certain rules， these rules are largely 100 million years of evolution of human brain left the limitations and obstacles （this is the category of Cognitive Psychology）， playing an analogy， from to solve the interaction design principles of cognitive psychology is the psychological and physiological characteristics of virtual instrument matching problem and the. The so-called "mental model"， a variety of interactive principles， and so on， are derived from the cognitive psychology of human cognitive ability research and understanding.

People's learning and adaptive ability is very strong， we quickly learned how to use the method such as computer， mobile phone， but also gradually formed some consensus "model" - controls， such as buttons， （but the control itself continued evolution and change in）. However， due to the rapid development of technology and commerce， the evolution speed of the information system is the result of the development of the information system.
