Help blind people move with ... gloves

Instead of using a walking stick or specialized glasses, visually impaired people can walk easily with the aid of movement using sound waves.

That is the product "Moving support gloves using sound wave sensors for the visually impaired" by two young people Lam Vu Hoang and Tran Quoc Co (Le Hong Phong specialized high school in Ho Chi Minh City). The topic won the first prize in the 2015 National Science and Technology Competition in the South.

Sharing the reasons for implementing the topic, Mr. Lam Vu Hoang said: "People with visual impairments often face many difficulties in traveling, affecting their lives and daily life. However, in the market now Only the products of sticks and glasses with relatively high prices are not suitable for the relatively poor economy of the blinds, therefore, when choosing topics, I and Co have an intention. Research a product to help visually impaired people travel more easily at a low cost, helping you reduce difficulties. "

On the outside, the gloves support moving like normal gloves, only equipped with a relatively compact sound sensor . "When using, users only need to sweep their hands in the fan shape and sound waves will be emitted. If there is an obstacle in front of them, the sensor on the glove will be located and then vibrated, so that blind people can know the object front bumper to avoid ".

Products "Gloves that support movement using sound wave sensors for the visually impaired".

Quoc Co said that to study successfully, the two of you have spent more than 8 months from the idea up until you complete the product. During this time, you are free to come back to Nguyen Dinh Chieu blind school and Bung Sang to find the testers."The first time when the product is not finished, some of you are wondering why the gloves have so many wires, so wear it if there is an electric shock, going on the road where the gloves are out of battery. What should we do . From then on, we have been trying to optimize our research products. When it is complete, our products are highly appreciated by the teachers in the school. The school also promised to find sponsors to commercialize the product, to bring this glove to many people, which is the greatest joy we have received. "

In particular, the moving support glove using this sound sensor can accurately alert obstacles both in the opposite 3 parts of the body (head, body and lower range), helping users to be safe. mind moving easily. Thanks to the use of simple, easy-to-buy devices on the market, this glove is only about 250,000, much cheaper than the road or eyewear sticks for the visually impaired. was born earlier.

"Next time, we will be equipped with additional lighting and sound support equipment, helping blind people to warn people around them to be able to cross the road more actively. In the future, instead of being a glove, we also plan to turn this product into a bracelet or watch to increase the aesthetics, along with lowering the cost of products to the lowest possible level to help. More people than those in difficult circumstances, ' shared Quoc Co.
