Opis:: The article presents the concept of a system for identification of dangerous areas in the urban area targeted at the people with visual dysfunction. The idea of the system is presented comprising the attempt of application of the wireless data transmission: IR - infra-red; BLUETOOTH; RFID. The consideration comprises also the identification of the object (human), identification of the movement direction (double barrier), wireless data transmission with data on the given dangerous area, excitation of the vibration information and the feedback of the system. Also the subject of optimal installation on the urban objects was discussed. The article is a realisation of the research task in the project called "The development of the method for marking of the dangerous areas and especially important places in urban area for visually impaired people with use of the wave-vibration markers".

Opis:: The paper constitutes a summary of the work carried out under the research project entitled The development of the method for marking and identification of the spots dangerous and of special importance for vision impaired persons in the big city with use of the wave-vibration markers. This article discusses key researches conducted during the project, including review of influence of environmental sounds on orientation and mobility of blind and partially sighted people, results of vibration perception threshold measurement taken at the wrist of both hands, measurements of paraseismic vibrations and results of researches on annoyance, recognizability and easiness to learn of selected signals.

Opis:: The article constitutes the continuation of the works realized under the research project entitled: "The development of the method for marking and identification of the spots dangerous and of special importance for vision impaired persons in the big city with use of the wave-vibration markers". The consideration included the identification of the object (human), identification of the direction of movement (double barrier), wireless data transmission with the information on the dangerous area, stimulation of the vibration signal and the feedback of the system. This article presents the result of choice of the optimal solution regarding the installation of the system on the selected objects of the urban engineering and also presents the concept of the method of modelling of the shape of the zone that is used for marking of the dangerous spot.
