Cognitively Driven Interface Design And Evaluation Of Cai System

As the global scientific and technological innovation has entered an unprecedentedly active and rapid development period,the continuous emergence of high-tech products and new materials not only represents the improvement of people's living standards,but also indicates the increasingly fierce competition for innovation among global enterprises.Only by mastering advanced innovative technology and innovative methods,at the same time,shortening product r&d cycle can enterprises survive and develop in the environment of economic globalization.Therefore,as an important tool for enterprise product research and development,Computer Aided Innovation system is also facing many challenges.At present,the research on CAI software system mainly focuses on the optimization of its functions and innovation process to assist users in innovation,while ignoring the important auxiliary role of CAI software system interaction interface on users' innovative thinking.This thesis mainly studies the role of cognition in the production process of innovative thinking,and then improves the interaction of CAI software interface through cognition and relevant theories,so as to improve the problem that the existing interaction interface of CAI software system leads to the loss of innovative thinking of researchers.Finally,assist designers to build a more efficient and user-friendly CAI software system interface.The main contents of this thesis are as follows:1.Research on the interaction interface of existing CAI software system.By using the method of mouse track recording experiment and user interview,this thesis analyzes and studies the user's interface operation behavior and user psychology of CAI software,finds out the problems that affect the user's innovative thinking in the interaction interface of the existing CAI software system,and then summarizes the problems.While verifying the necessity of the thesis research,it also clarified the goal and direction for the later research.2.Research on the cognitive mechanism of innovative thinking.Cognition is the psychological motivation of the generation of innovative thinking.Through the information processing model of cognitive psychology,it can be known that three cognitive activities,namely perception,attention and memory,are the important prerequisites of innovative thinking.On this basis,the important role of three cognitive activities in the generation of innovative thinking is deeply studied,and the cognitive process model of CAI software assisted users in the generation of innovative thinking is constructed to provide theoretical support for the improvement of the interaction interface of CAI software system.3.Improvement principle of CAI software interaction interface based on cognition.Through the research on the characteristics of human perception,attention,memory and other cognitive activities,combined with the functional characteristics of CAI software and the problems existing in its interface,this thesis puts forward the improvement principle of CAI software interaction interface based on cognition,and provides specific methods for improving the interaction interface of CAI software.4.Build a improvement design process of cognition-driven CAI software interaction interface.Aiming at the problems existing in the existing CAI software interaction interface,and based on the principle of improving CAI software interaction interface based on cognition,the design process of improving CAI software interaction interface is constructed.This process mainly includes five steps of CAI software interaction interface problem classification,interaction interface function module optimization,interaction interface details and layout improvement,interaction interface test and evaluation and other interface improvement design.Finally,the rationality and effectiveness of the process is verified by the example of CAI network software developed by the team.
