Glasses for visually impaired

It is not necessary to have offices around the world and billions dollars in banks to create high-tech devices useful to people. Employees from St. Petersburg, whose staff consist of only nine people, proved this. They invented 3D-glasses for the blind. Notably that one of the authors of the gadget is Maxim Spiridonov who is disabled from childhood.

How does it works

Initially device developers tried to find some ready solutions in this area to further improve it. However, it appeared that there were no developments in this direction. They had to start from scratch, but this does not become an obstacle for engineers.

The set of equipment that allows people with vision problem to gain independence includes:

Conventional glasses supported by a pair of miniature cameras;
The navigation unit, battery pack and a small computer.
Thanks to function object recognition system calculates the distance from the person to the obstacles standing in the way of the blind, and provides voice and audio prompts. Also, the ability to distinguish colors light, read the bar code printed on the product packaging. The information captured by cameras is sent to a computer that processes the data, then transferring them to the speaker in voice form.

The device does allow blind people to avoid collisions with obstacles. For example, cane with which the blind person moves, could pass a high barrier near a sidewalk. A person in this situation will stop only when physically feel obstacles that could cause injury. Electronic program will notify about anything that stands in the way of things in advance, which will avoid contact.


The novelty provoked a great interest in worldwide. Soon should begin mass production of three-dimensional glasses for people with vision problem. To do this, it is necessary to make the device more convenient to use and improve its outlook. The first fully advanced gadget will get Maxim Spiridonov, because it is thanks to his efforts blind find more independence and glasses will make their life a little more comfortable.

Our guys Panferov Alexander and Dluzhevskyy Andrew were successful in the regional final of of the international competition “Golden Bytes’. With the project “Program for training the blind to read Braille.”

In the Start-Up category they took second place. Despite the fact that to the final go only the first place in each of the nominations, we were invited to participate with the project in the final of the world contest in the nomination Intel Edison.

Museum of Art for the Blind

Prado Museum in Madrid has opened a unique exhibition of copies of famous paintings that were created specifically for visually impaired visitors. Using 3D printing technology, these paintings were made in the form of reliefs that allow blind even to his own “see” painting techniques and strokes of Correggio and other artists. In paintings for visually impaired guests museum has texts using Braille and audio guides, and sighted visitors may be asked opaque glasses to test the same feeling.
This initiative opens museum for all. Not surprisingly, the exhibition enjoys great success among Madrid Society for the Blind. Jose Pedro Gonzales, 56-year-old man who went blind at age 14, told reporters: “It’s incredible. I feel this painting up the details ».
The exhibition includes five paintings: “Touchy” Correggio, version of the famous “Mona Lisa”, written by a pupil of Leonardo da Vinci, “Umbrella” Goya, still-life painter of the Renaissance Van der Amen, “Apollo in the Forge of Vulcan” Diego Velazquez and “Knight with hand on chest ” El Greco – six gems from the collection of the museum.

Of course, the Prado Museum is not the first museum that draws attention to the visually impaired. Trade shows of tactile paintings and sculptures were previously organized the Metropolitan Museum in New York, the National Gallery in London, the Louvre and others. But few have used advances technology 3D-printing. The curator of the exhibition at the Museum of the Prado says that they are the first who added color to the 3D-pictures. “For us it was important to add color, because visualy impired often can still perceive some color,” – he told the New York Times.
Relief paintings were created in cooperation with the Museum of Prado 3D-printing Estudios Durero. They have developed a unique 3D-printing process called Didu, which, in fact, working with chemical ink, which is caused by ultraviolet radiation can create volume. This type of 3D-printing is very expensive. It is reported that a copy of a picture costs about $ 6680.

Employees printing chosen and highlighted the features of each texture pattern, which are important for tactile contact: “In this respect, the small details that may seem insignificant at first glance become fundamental to understand the composition or theme of each image. After about forty hours of processing each picture image is printed with a special ink. Then (after 12 hours) print the method that adds volume initially flat elements. So we get a picture of the appropriate size, which you can touch with your hands. As a result, created version of the picture, which is not only very similar, but has a special texture across the surface. “

Game for such audience should be based on sound, not the picture. It will need to focus on the sound, which must be passed by volume and create a realistic world through stereo recording.
Dowino design studio created this game called Blind Legend, which has successfully raised funds for its implementation.
The game tells the story of the blind knight. The story begins with the kidnapping of his wife. The knight is going through thick forest to rescue her, and his daughter comes to help him. Controls of the game will be simplified.
