Research On Interaction Design Of Human-Machine Interface Of Maglev Vehicle Based On User Experience

With the rapid development of urbanization,our country has made great development of urban rail transit.In recent years,the maglev cars of the trackless contact have attracted more and more attention because of its fast,safe,comfortable,flexible and convenient advantages.The human-computer interaction system of maglev vehicle mainly interacts with passengers through the on-board central control screen.However,there is a lack of relevant research on the human-computer interaction system of maglev vehicle,and some problems exist such as low interaction efficiency and poor user experience.Based on specific school-enterprise cooperation projects,this paper starts from the user experience and conducts research on the design,development and decision-making of the human-computer interaction system for maglev vehicles.Under the premise of meeting the basic functions of maglev vehicle users’ needs,it aims to improve people’s travel efficiency and ride experience,and promote the development of urban rail transit.First of all,centering on user experience,collect user needs through qualitative and quantitative user demand research methods,use the KJ method to sort out,eliminate and classify preliminary user needs;use the AHP to build a user demand hierarchy model,calculate the weight of user needs and Prioritize and sort user needs,and establish a systematic,real,and comprehensive weight model of user needs.Then,centering on user needs,in the structural layer of the five elements of user experience,the user needs are transformed into product functions through the Y model theory,and the navigation structure design of the man-machine system of the magnetic levitation vehicle is carried out;the functional structure diagram of the product is constructed in the framework layer,Carry out prototype diagrams and interactive design for the man-machine system of the maglev vehicle;coordinate the design specifications at the presentation layer and produce highfidelity design schemes based on the prototype diagram.Finally,design decisions are made on the beauty of the interface of the design scheme based on the calculation method of beauty;combined with the four beauty image factors of balance,integrity,simplicity and unity,the layout of the man-machine interface elements of the magnetic levitation vehicle is quantified,and the analytic hierarchy process is used to The system calculates the objective weight of the beauty factor,and finally optimizes the best design scheme.Based on QT creator,instantiate the programming of the best design scheme,establish the communication between the man-machine system and the controller of the maglev vehicle through the serial function in QT;finally program the design scheme and apply it to the actual project experiment,further verifying the design feasibility of the program.Starting from the needs of users,this paper explores the application of the five-element model of user needs,AHP,Mido Computing,and QT creator in the design and development of the human-computer interaction interface system for maglev vehicles,providing a basis for the research on the interaction design of domestic urban rail transit vehicles.It has a certain practical application value.
