Visual Attention

As society develops, people's travel environment has become more complex. Normal in this environment often encountered travel difficulties, the blind more so. Blind in today's environment, successful life, blind people need a sound and rational guidance system. Accelerated economic development concerns of blind people, blind guide system services in the community, but also embodies the spirit of the city. Care for the blind is the performance of social civilization and progress, it also reflects the development of civilization and the human spirit.Blind guide system combines ergonomics and environmental psychology and other disciplines, the key is to fit the specific needs of the blind. In this paper, research-oriented system, the current status of the blind, blind as a survey of the characteristics and demands, which summarizes the existing blind guidance system problems and needs improvement. In this paper, ergonomics and environmental psychology theory put forward to solve the problem, and on this basis a specific program design.In this paper, the first chapter discusses the background research for the blind and meaning-oriented system, the second chapter, the author of the current state-oriented system for the blind survey results, the third chapter, on analyzing the characteristics of the blind, to understand its characteristics Based on the summarized out their greatest needs. Chapter IV using the object's position based on the test multiple perception channels drawn from the blind guidance system is feasible. Combined with ergonomic and environmental psychology theories, summarizes some aspects could be improved. Chapter V the most use of the blind based on the value of the design elements of the program, have great practical value. At present, the barrier-free guidance system design theory is not perfect, I will be in the previous proposed based on personal recommendation, seek solutions to further meet the travel needs of the blind, to be more efficient, safe, convenient way to provide them with A guidance system of environmental information. By asking questions-Analysis problem-solving process to design a new set of blind-oriented system, in order for the city we live in a more humane, more harmonious for the effort.
