What new devices are designed for the visually impaired?

It is believed that about 80% of information a person receives through his vision. However, this figure is highly dependent on how well we see. There are very few people with excellent vision. Many begin to lose it at school. Photo: Depositphotos This is connected not only with small prints in textbooks, but also with the spread of computer literacy, when you have to strain your eyesight due to a poorly configured monitor. As a person grows up, vision gradually “sits down.” I have to buy glasses. But they do not always fully restore normal vision.

There are more and more visually impaired people in the world. Vision problems make life difficult for them. Let us dwell in detail on how scientists and specialists help these people to feel useful in society. It will be about various electronic devices that have appeared in recent years. It is extremely difficult for visually impaired people to use mobile phones. They are now of two types – push-button and touch. In this and in another case, a visually impaired person cannot do without a magnifying glass. Small numbers and letters on the keys are almost invisible even to a person with normal vision, since the keys themselves are scanty. Often it’s hard to hit them exactly. Sensors are even more complicated – they respond to any movement of the fingers on the screen. Sens Inclusive Phone Photo: Source I think the Sens Inclusive phone, invented by Japanese Takumi Yoshida, deserves the highest ratings.

As you know, in Japan a significant part of the population has low vision. A man without glasses in this country is a rarity. Takumi Yoshida created a phone where the font on the buttons has a raised (raised) look. Enough for a set to hold with your fingertips to understand what numbers and letters are below them. The phone number of the interlocutor or text for SMS can be dialed even at random – in complete darkness or gropingly in your pocket. A big plus is that when you click on the buttons there is a tone confirmation. An important addition – the phone responds to commands given by voice. You don’t have to search with your fingers for the buttons responsible for calling, sending or deleting. Just say a word.

ъDifferent color backlighting will let you know exactly what mode the device is in. Another interesting device is a wristwatch for the visually impaired. They first appeared in Japan, are available in several versions. Including in other countries. The simplest watches have a transparent cover that opens by pressing a button. Touching the arrow with your fingertips, you can find out what time it is up to minutes. True, it will require training. Other watches also have an opening lid, but instead of hands, small magnetic balls of different sizes move along two grooves. They are easy to feel with your fingers. Another type of watch is voice speaking time. By the way, they are very popular among people who see well. For those who have completely lost their eyes, wrist watches with Braille numbers are produced. The time is determined by fingers (to the touch) by the size of the raised font (it is associated with the clock mechanism). An interesting and unusual electronic device for visually impaired and blind people was also invented in Russia. This is a portable motion sensor when it is difficult for a person to quickly notice an obstacle and dodge it. Anything can be such an obstacle.

For example, a fence, a wall, an oncoming person, an approaching car … The device emits ultrasound. A person does not hear these frequencies. The ultrasound reflected from the obstacle enters the sonar (it is located on the cord on the neck of a person) and translates into a normal sound signal. With a dangerous approach, the signal becomes constantly sounding. The device called “Guide” first appeared on sale in Yakutsk, where it was invented. True, the market price stops – 13 thousand rubles. But this can be compared with the cost of a mobile phone of not too high class or the cost of a computer tablet.
