Research Into The Visual Information Barrier-free Design For The Urban Orientation Identification System

Currently, the urban public environment orientation system has not yet benefited different groups of people equally. In other words, the orientation function has not yet accommodated to demands of all people, such as those with vision disorder. Due to the ignorance of demands of the population group in the urban orientation design, they are faced with many obstacles during the information reception in the public life. This not only brings inconvenience to their physical activities and hurt their heart, but is also unfavorable for the development of urban civilization. Therefore, this paper attempts to introduce the concept of visual information barrier-free design into the urban orientation design and formulate the visual information barrier-free design standards for the urban orientation identification system so as to allow people with vision disorder to share the urban culture achievements. First, this paper conducts a detailed and in-depth survey of the development background and relevant research of barrier-free design for urban orientation identification system and the visual reception capability and judgment capability of people with vision disorder. Then, from the professional perspective of visual communication, the factors influencing the barrier-free information transmission are explored. With people with visual disorder as the major research object of this paper, their physical characteristics and psychological demands are analyzed at an attempt to enhance and supplement their sense organs. Based on the above analysis and discussion, a set of “visual information barrier-free” orientation design theories and standards are designed so as to provide reference for the employment of visual information barrier-free design concept. The authors hopes to expand the research objects to the other vulnerable groups to study the issue from multiple perspectives and contribute a little share to the establishment of a barrier-free public environment and a harmonious society.
