The invention relates to medical technology, namely to means for the rehabilitation of the blind, and can be used for the movement of people on the streets, on railway platforms in the subway, in industrial and domestic premises.

The purpose of the invention is to increase the safety of movement and to enable orientation at the places of turns and intersections by using signals from a metal detector that records the position of metal marks on the road surface, and.

Fig 1 shows schematically a device for targeting people with impaired vision, side view; in fig. 2 is a section A-D in FIG. 1; in fig. 3 is a section BB in FIG. 2

The device contains a portable meta-detector 1 with a sound signal sensor 2 and an orientation fixture made in the form of a road surface 3 with metal plates 6 installed at the corners 4 and intersections located perpendicular to the longitudinal axis of the coating.

The device is used as follows.

Depending on the number of laid metal plates 6, for example steel, the direction of movement of a person is determined. For example,

with two plates - turn right and left, with one - to the left.

When moving along the pavement 3, when a person approaches the metal plates 6, the metal detector 1, located on the human body, gives a signal telling him to cross plate 6 or turn left, passing between the two plates. When you reach the right turn, the orientation adjustment tells the person where to go next.

The device allows you to ensure the safe movement of people with impaired vision without assistance and without a cane, to expand the possibilities of communication.
