The Concept of a System for Identification of the Dangerous Areas for People with Visual Dysfunction.

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".
