Research On The Usability Of Interface Based On User Cognition

In recent years,with the continuous upgrading of consumption,the user's demand for personalized accommodation presents a diversified trend,and under the encouragement of the national strategy of "global tourism" and "Rural Revitalization",online C2 C accommodation platform represented by Airbnb,Xiaozhu and woodbird has developed rapidly.When booking accommodation online,the user's attention is limited in the face of a large amount of room information.Most users will soon enter a cognitive mode based on reading pictures,quickly generate an impression of accommodation through pictures,and make decisions.In addition,homestay is personalized and non-standard,with different user preferences,which determines that the user interface must introduce the real face of homestay to users comprehensively and clearly in a short time,so as to avoid the omission of key information caused by cognitive habits,attention fatigue and other factors.Cognitive psychology holds that human's information processing mode is a dual processing mode,that is,the combination of the automatic processing mode dominated by body instinct and the active processing mode influenced by subjective factors such as expectation,motivation and belief.For the online homestay platform,visual cognition is the most important way to realize its value function,so the research on its visual usability is an important standard to evaluate its comprehensive usability.The author will use eye tracking experiment+subjective visual usability questionnaire to explore the impact of different visual design elements(graphics,text,color,space,etc.)on the user's visual information cognitive effect.Based on the practical results,the author will put forward relevant design guidelines and suggestions for the current C2 C homestay platform interface visual design.This paper mainly consists of five parts:the first part(Chapter one and chapter two)is the introduction and literature review of the research.Through combing the background of the research and literature in related fields,we can get a comprehensive understanding of the research topic and a relatively scientific research method and process.The second part(the third and the fourth chapter)is the empirical research part.In the third chapter,the author first establishes the main idea and technical route of the empirical research,then studies the information content that users pay more attention to through the questionnaire survey,and then analyzes the usability problems of the current mainstream online accommodation platform based on this,and finally puts forward the classic usability indicators The usability evaluation criteria of 7 dimensions including information memory rate and conversion rate are proposed.In the fourth chapter,on the basis of user scenario test,the cognitive effect of information cognitive process variables such as different interface display interaction mode,information quality,information audience and so on is tested by combining the auxiliary methods such as questionnaire survey and eye tracking.Through the comparison,a relatively good interface display mode is obtained,so as to establish different user interface cognitive psychological model,and the experimental results are analyzed At last,the guiding principle and optimization strategy of online home stay interface design which can effectively improve users' cognitive psychological effect are put forward.The third part(Chapter 5)designpractice and verification,Chapter 5 according to the relevant principles and strategies,and college students as the target group for design practice,and the final page for users and experts evaluation.The fourth part(Chapter 6)is the conclusion and prospect,which summarizes the whole research process and makes a prospect for the future research.
