| Our country’s space strategy has implemented a "three-step" plan.The current main structural cabin of the space station has been constructed and the astronauts’ long-term residency mission has been realized.The control cabin of a manned spacecraft is a hub where man and machine meet.It consists of a large number of display and control components and has a very complicated structure.The rational design of its man-machine interface is crucial to the successful completion of space missions.Relevant studies have found that the microgravity environment will have a certain impact on the perception of astronauts,which can lead to changes in visual function such as narrowing of the field of view,poor contrast sensitivity,and increased intraocular pressure.Color can affect people’s subjective feelings,and then affect people’s behavior.A reasonable design of the color of the cabin human-machine interface can improve the mental state of astronauts,enhance environmental comfort,reduce accident rates,and improve work efficiency.At present,most of the research on human-machine interface exists in the space layout,and there are relatively few researches on the color quantification and color design of the spacecraft human-machine interface.This paper summarizes the commonality of the human-machine interface by studying the human-machine interface of the spacecraft and similar cabins.Color and personality color,classify and expand quantitative color samples,and form a color matching scheme based on color imagery and mission requirements,which can provide a reference for the color design of spacecraft human-machine interface.The research mainly includes the following:The human-machine interface colors of spacecraft and similar cabins are studied and quantified,and the initial color samples are obtained by summarizing the common and individual colors of human-machine interface colors.Since there are few resources related to manned spacecraft,the human-machine interface resources are collected and arranged with reference to similar cabins with complex structures and complex human-computer interaction,such as space stations,high-speed rails,and space shuttles,and the K-means clustering algorithm implemented by Python is used.The colors of similar cabins were extracted and fitted,and subjective visual chromatic aberration evaluation and image evaluation were performed on the fitted samples.The extracted color samples were divided into chromatic and achromatic,and 5 main color samples and10 color matching were obtained.Background sample.Increase the number of color samples to get dominant color attention samples.Analyze the color elements and expand the 5 main color samples,and get 10 samples for each main color.A total of 50 samples are used for the main color eye movement selection experiment.The eye movement index data is imported into SPSS for principal component analysis.Combined with eye movement Hotspots and gaze paths select the 3most striking samples of each dominant color for the center sample of the color palette.Regression analyzes the influence of saturation and lightness on attention,and obtains the relevant regression equation,demonstrating that attention is affected by changes in sample saturation and lightness.Screen the color matching eye-catching samples,and classify the samples to build a color reference case library.Match the eye-catching samples extracted from each main color with 10 achromatic backgrounds,conduct eye movement experiments and principal component analysis,and select the three most eye-catching samples for each main color and background color.3*5*3=45 color matching samples,as the initial sample of the sample case library.All color samples are classified into categories,allowing designers to perform sample retrieval.The constructed sample library can provide color reference samples for the color design of spacecraft human-machine interface,and can also provide reference for the color design of human-machine interface of other products. |
