The Symbology Research Of Helmet-mounted Display Based On ERP

Helmet-mounted display system is widely used for modern fighter information transmitting system.HMD can provide flight data information needed for the pilot,also can provide guidance for many tasks,it’s one of the important equipment on the plane.ERP technology is the new technology of cognitive science researching,it reacts to the people’s cognitive directly,and it has the advantages of timeliness,completeness.The ERP technology to the study of HMD is not only a kind of new thought,also a kind of good method,having very strong realistic meaning and value.In this paper,first of all,the technology analysis of ERP research was be raised,including its concept and technical principle,and then a brief introduction to the development process of the helmet-mounted display,then information content of F-3 5’s HMD display interface was presented.Then the research divided into two parts,the design method and the evaluation of symbol,in terms of symbol design,some symbol design requirements and design principles were given,and some improvement design based on the principle of F-35 HMD were given;in terms of symbol evaluation,this paper summarized some commonly evaluation methods and advantages and disadvantages of them.After finishing the preparation of relevant knowledge,two sets of ERP experiment were carried out in this paper.The first experiment was to select a set of symbol design improvements to experiment,P300 was chosen as component for research;the second experiment was to select a set of symbol design carried on the experiment,P200 was chosen as component for research.Experiments proved that the design of HMD symbol associated with ERP components,contributing to the design of the HMD symbol optimization and improvement of assessment,and providing guiding significance.
