A system for identification of dangerous spots and POIs for the blind and visually impaired

摘要

The paper presents the course of work on construction of a prototype system for demarcating dangerous areas and points of interest for blind and visually impaired people in large urbanized areas. The project included identification of locations requiring to be marked, development of the method of marking the identified zones, and designing the transmission/reception system for identification of both zone and user. Further, vibration signals to be used for conveying information to the user were selected together with the method of teaching blind and visually impaired persons (including children and young people) in identification of dangerous spots and points of interest (POIs) in a large city environment with the use of the proposed system. The paper shows consecutive stages of development of the transmission/reception system and its final effect in the form of a prototype.
