abstract="Since 2009 the project System For Determination Of Hazardous Areas For The Blind People Using Wave-Vibration Markers has been in constant development. Its first stage was the public opinion survey. The aim of the survey was to analyze and evaluate problems associated with movement of the blind and partially sighted people through an urban environment. This article presents results of research on possible application of paraseismic vibrations and problems with paraseismic vibrations in the system for spatial orientation of blind and partially-sighted people which is built. Particular attention was paid to methodology of signal acquisition of paraseismic vibrations for the purpose of education of spatial orientation of people with vision dysfunction. Finally the frequency bands of vibrations generated by means of traffic and transport in various places and situations in the city are defined. These frequencies allow better designing of the system that support movement of blind people in urban conditions.<p /> <p>Language: en</p>",
