FIELD: medicine.
SUBSTANCE: invention refers to products facilitating the life activity of sight-impaired peoples, specifically aims at obtaining the information and assisting the space orientation of blind individuals. A method for the space orientation, navigation and information in the individuals suffering visual dysfunction consists in the fact that a radio beacon placed in one orientation point is used to transmit radio-frequency signals, while a radio informer in the possession of the individual is used to receive these radio signals and to transmit them to a body exposure device making signals of the orientation point being in a close proximity. At first, the radio informer transmit the radio signals, while the radio beacon transmit the radio signals after the radio signals from the radio informer have been received by it to inform on the individual being within the detection zone. Once the radio informer receives the radio signal, an intensity of the radio signal is measured to provide a basis to vary a human exposure parameter and to determine the radio beacon approach direction. The system comprises the radio beacon for placing in the orientation point, and the radio informer in the possession of the individual. The radio beacon comprises a source and a radio signal receiver, and a control unit. The radio informer comprises the source and the radio signal receiver which is connected to the human exposure device.
EFFECT: using the invention enables more precise orientation and chokes the air with the unwanted information.
