HELMET FOR ORIENTATION OF THE BLIND IN SPACE

摘要

The utility model refers to technical means that allow people who are blind to navigate in space. The helmet for orientation of the blind in space contains a housing, on the outside of which an information processing device, a power supply and a control unit are installed in its back part, and an ultrasonic distance sensor and a video camera are located in the front of the housing, the lens of which is located in the central part of the helmet. The helmet is equipped with headphones, and an LED strip is fixed on the side surfaces of the helmet. In the domed part of the inner shell of the housing, uniformly spaced identical recesses are made, in each of which an electromagnet is placed. Each electromagnet contains a coil on a coil that is secured in a recess. The silicon electrical steel core is placed inside the coil with the possibility of axial vibrating reciprocating movement, providing a tactile effect on the human scalp. A locking disc is attached to the end of the core protruding from each coil towards the outer shell of the helmet, between which and the corresponding end of the coil, a spring is put on the core. A retaining ring is put on the part of the core protruding from the coil towards the person's head, behind which the protruding end of the core is rounded. An ultrasonic distance sensor, a video camera, an information processing device andControl block. The ultrasonic distance sensor and the video camera are connected to an information processing device, which is connected to a control unit, which is connected to headphones, an LED strip and to the winding of each electromagnet. EFFECT: expanded arsenal of means of orientation of a blind or visually impaired person in the surrounding space. 1 wp f-ly, 3 dwg
