Digital interface has gradually replaced the traditional human-machine hardware interface and become the main carrier of the human-computer interaction for information intelligence system nowadays,widely used in fighter,ship driving,nuclear power plant control,battlefield command,special engineering vehicle driving and so on.The digital interface of the complex information system provide evidence for the operator to make decision and even the operate,playing an irreplaceable role.Because of the presented large amount of monitoring information and complex information relations,the operator is easy to enter the situation of complexity cognition,which may cause operational errors,misreading or miscarriage,feedback lately and other cognitive difficulties which lead to failure of mission,even produce a system failure or a heavily accident.Therefore,the quality of digital interface design directly affect people’s information acquisition,judgment and decision-making.Therefore,how to design digital interface for the complex systems is a critical problem for current academic and engineering design research.The Engineering Vehicles-Digital Human Computer Interface(EV-DHCI)studied in this paper,is a new field of special engineering vehicles after the application of electronic communication technology,computer network technology and database technology.Based on the project of ‘wireless remote control and obstacle elimination technology(ZLB13103)’,this paper puts forward a digital human-computer interface design method for engineering vehicles based on perceptual information from the view to satisfy users’ perceptual demand on the basis of the study of user cognitive information processing mechanism,and considering the cognitive overload and cognitive misalignment are ubiquitous cognitive problem in the digital interface design field of complex system.The main research work includes:1.Research the concept,characteristics and connotation of digital human computer interface and perceptual information,and then under the guidance of user-centered thought,do the digital man-machine interface perceptual cognitive research based on the cognitive knowledge processing and cognitive load.The strategy point of view to meet the user’s perceptual cognitive needs is proposed to reduce the user’s complex interface digital interface cognitive difficult.2.Analyze the relationship among the design characteristics of DHCI,user’s task activity and user’s cognitive activity,establish the digital human-computer interface perceptual cognitive model and put forward the corresponding design principles after depth analysis of the user’s perceptual factors and emotional behavior on basis of the comprehensive cognitive model of the engineering vehicle operator,used to guide the study of EV-DHCI design based on perceptual information.3.Study the representation method of perceptual information and interface design features respectively: the method of characterization based on semantics is applied to the perceptual information representation,the FA-CA method is used to analyze and simplify the perceptual information and a method based on extended visual semantic cognition(EVSC)is presented for digital human-computer interface design features representation.4.Divide the main body involved in the perceptual demand acquisition of EV-DHCI and establish perceptual information transfer model of each subject.Obtain the semantic information semantic library for EV-DHCI based on the study the cognitive differences experiment of each design subject.Construct the perceptual information dimension system on the premise of merging the perceptual information based on the entropy weight method.5.Explore the relationship and quantitative solution between the perceptual information and the interface design features in the design of EV-DHCI based on perceptual information.Proposed a nonlinear mapping method by combining the gray theory and the neural network to solve the problem of limited training sample of DHCI scheme,so as to deal with the relation between the perceptual information and the interface design feature set,and verify its matching ability by case.6.Propose a decision-making method of Fuzzy Technique for Order Preference by Similarity to an Ideal Solution(F-TOPSIS)to rank the multi-attribute perceptual information design scheme of DHCI by case to meet the user’s expectation of interface scheme with multiple perceptual information requirements,providing effective support for decision making problems of how to improve the accuracy of program generation and customer satisfaction. |
