“Rukep” presented an advanced development of ultrasonic “vision” for people with visual impairments
The Rukep company, which specializes in the creation of devices in the field of local positioning and visualization of 3D content, has improved its development of ultrasonic “vision” for people with visual impairments. The device works on the principle of echolocation and has a flexible rim that is attached to the headgear. Vladyslav Ovchinskyi, Minister of the Government of Moscow, Head of the Department of Investment and Industrial Policy, told about it.
The device works on the principle of echolocation (like the vision of bats, which receive data about the surrounding world using ultrasound reflected from objects. According to the developers, studies have shown that in humans, echo signals, like light signals, are sent to the visual area of the brain, where they are processed into a three-dimensional . picture of the world During training, you can learn to “see” the environment with the help of ultrasounds, as well as with the help of vision. The idea to apply the principle of echolocation to create a device that helps people with poor eyesight “see” came to the company more than 10 years ago.
“Echo Sonar” was originally made in the form of a helmet, because it was essential to use it on the head. The sound wave reflected by the device is completely digitized and transferred into the range of frequencies that can be heard by humans. The loudness and shape of the signal allow you to distinguish between objects. Due to the presence of two independent channels for receiving echo signals spread across the front, the user receives a three-dimensional sound picture of the surrounding world.
Even at the stage of the larger first version, the device was tested in Kazan, where blind participants of clinical studies learned to decode ultrasound signals. After two months of training, testers of the device were able to accurately determine the dimensions, location of objects and the configuration of space in general.
With the help of new materials and an elemental base, the developers have reduced the dimensions of the device to a flexible rim that is fixed on the headdress. The range of the device is 2-3 m, for long distances it is possible to connect to GPS navigation via a smartphone. The company is looking for an investor for the commercial implementation of R&D.
