The Quantitative Research For The Impact Of Building Visual Perception By Human Visual Resolution

It is widely acknowledged that people cognize the outside world mainly by theirvision, that is to say, visual sense is the principal approach for human beings to acquireinformation from the environment. Architecture, being regarded as a subject combining artand technology, shares a vital common point with such fine arts as painting, sculpture andcalligraphy, which is, passing on beauty by means of vision. Architectural space isperceived mainly through vision, based on this viewpoint, a detailed analysis on theconnections between the distance of observing a building and its surface texture had beenproposed by a Japanese architect, Ashihara Yoshinobu, who has drawn to a conclusionknown as a D/H architecture visual theory, which, had been recognized worldwide. The20thcentury had witnessed the development of the researches towards architecture visualperception, a large amount of scholars has been engaged in the research of spacequantization，however, there are too many quantifying methods for them to reach anagreement. Professor Xiong Ming has proposed a theory of computing visual field amongbuildings, promoting the research of space quantization, significant as the theory may be，yet in which there are still some limitations. Proceeding from the research on architecturalvision cognition, this paper intends to explore how human visual sense affects spatialcognition and the resolution of architecture and its details at different observing distances.This paper is aimed at studying the influence that visual resolution exert on spatialperception in architecture visual field, via the research of visual character of human eyes，quantifying certain resolution when observing buildings at different distances, thusimproving and perfecting the existing theory of visual field among buildings, so as toclarify visual cognition of different materials and constructional element scale. Meanwhile,on the basis of research findings on physiology of vision and specific feature of theexternal architectural space, this paper also utilize mathematical algorithms to grade spatialcognition, finally arriving at generalizations of visually spatial perception.Architecture of different periods give diverse influence on observers, Chinese ancientwooden buildings make people feel pleasant and easy to approach, while Europeanmediaeval cathedrals call up the sense of reverence, however, when it comes to theskyscrapers built nowadays, with curtain walls made of glass, hardly had we felt delightfulwhen getting close to them. This paper intends to proceed from the study of visually spatial perception, then explore the primary reason why varying types of architecture and its skinbring about different visual perception by a comparative analysis of the visual resolutionfeatures of architecture built in different time periods.
