Research on Key Methods of Visual Human-computer Interaction Comfort Quantifacation in Multidimensional Information Space

Abstract

With the increase of information exchange types and the acceleration of information exchange speed, people not only pursue fast and efficient interaction effect, but also begin to pursue natural and harmonious human-computer interaction comfort experience physically and psychologically. Therefore, human perceived comfort has become an important index in the design of modern human-computer interaction system. However, since comfort is the subjective feeling of human body, it is difficult to realize quantitative measurement and evaluation in the design process, which brings great difficulties to computer intelligent human-computer interaction design and scientific evaluation. Vision is the most important sense of human beings. More than 80% of all kinds of information received by people from the outside world is obtained through vision. Vision is an important means of human-computer interaction in complex multi-dimensional information space, and it is also the most intuitive source and effect embodiment of human comfort perception. Through a large number of experiments, import the test data into the software Origin, and draw the change curve of visual comfort with reading time, which fit with the S-shaped curve as the reference. In this way, the relationship between visual comfort and reading time can be obtained. The mathematical model of the relationship between reading time and visual comfort is established, and experiments are carried out to verify the corresponding mathematical model relationship.
