Modern ergonomics concept and automobile interface design

modern mechanical and electrical products often boast that their design conforms to ergonomics principles, and take this as a selling point. Automotive products are no exception. The word "Ergonomics" is printed on the promotional materials of almost every new car. So, what is "Ergonomics"? What impact does it have on the design of cars

the author mentioned in "green wave and automobile", "man machine environment large system view and automobile design" that the design of modern machines should not only consider the functions of the machine itself, but also consider the relationship between machine and human, machine and environment. In this way, there are two boundaries: human machine and machine environment. Ergonomics is to study the boundary of "man machine" and monitor the time when the specimen cracks

people and machines work together. People have human characteristics, and machines have machine characteristics. To design a machine that can work in harmony with people to the greatest extent, we must fully study the characteristics of both in order to design a good man-machine interface. Based on the detailed study of human characteristics, ergonomics sets up a series of design criteria to guide the design of machine products, mainly the interface design between human and machine. Among them, the main ones related to automobile design are:

interface design based on human senses

for example, human vision has the characteristics of angle of view, field of vision, visible light wavelength range, color resolution, visual sensitivity, positioning illusion, motion illusion, visual fatigue and so on. These characteristics should be fully considered in the design of automobile windshield, instrument panel and instrument, so that drivers can get enough visual area, It can quickly identify various signals and reduce errors and visual fatigue. The design of traffic signs should also adopt colors that most people can clearly distinguish and shapes that are not easy to produce illusion

interface design based on human body shape

different regions and races, different ages and genders have different body sizes. Design for different regions and groups according to the requirements of GB 4806.6 (see Table 2 for the restrictions of GB 4806.6 on monomers in polystyrene resin) and ensure that the residues of ethylbenzene and styrene in their products meet the limit requirements. Cars should refer to the human body parameters of specific objects. Under the conditions of modern society, It is difficult to occupy markets in different regions with one product specification. People have different forms in life and work. The human body works in different postures, the bones and joints of the whole body are in different relative positions, the muscles of the whole body are in different tension states, the burden of the heart is different, and the degree of fatigue is also different

when designing a machine, we should first consider what body shape to use to operate. After selecting the posture, we should also consider supporting the human body in the most comfortable way, and appropriately arranging the position of the operated object, so as to reduce fatigue and misoperation. For example, when driving a car, the driver adopts a sitting posture. The design of the seat should conform to the best outline of human bones. The layout of the instrument should be easy to see, and the position of the joystick/board should be within the range of the flexible movement of human limbs

it can be said that it is a key interface design based on force characteristics

the fatigue degree of human body in different postures is different, and the force required to operate the machine should be selected within the range that is not easy to cause fatigue in the corresponding postures. 2. The characteristic fatigue after transformation. For example, the steering booster is designed to reduce the control force. The maximum pull and thrust of the human body in different postures are also different. For example, the pedal force of the human leg in sitting posture is about 20 degrees below the hip horizontal line, and the maneuverability is also good, so the brake pedal is installed at this position

the human body uses different muscle groups to work in different postures, and the flexibility, speed and maximum frequency of action are different. For example, the repeated stretching and stretching of legs has a lower frequency, while fingers can knock with a higher frequency. Therefore, corresponding to different operation frequencies, different action modes should be adopted to complete

interface design based on human brain characteristics

human brain has its own characteristics in its understanding and response to things, which is reflected in its behavior and response to the outside world. People like to deal with things with intuition, and are not good at cumbersome processes and accurate calculations. How to design human-machine interface has always been a hot topic for computers that help human brain work

this theme is reflected in the development from low-level language to high-level language, object-oriented and task-oriented programming, as well as the progress in graphical terminal, mouse positioning, window system, multimedia, visualization, virtual reality and so on. In recent years, artificial intelligence has been applied in cars. On board computers can help drivers recognize the road, shift gears, and avoid collisions. The Toyota pod concept car recently exhibited at the Tokyo International Auto Show can also record the owner's life and driving habits in order to provide more considerate services to the owner

it is no exaggeration to say that in modern society, successful machine products cannot lack the concept of ergonomics

then again, as business publicity, we cannot judge the quality of products only by the word "Ergonomics". Investigate, understand and even experience
