On a noisy road that even the mobile phone call noise is not much useful, they hold a foldable cane kept hitting around the front of the front, even if they are sensitive, they are helpless. Under the intertwined of various noisy sounds such as the roar of the car engine, they may even have a tone of the traffic lights.
Therefore, some blind people may rarely be willing to go out, the world outside, for them, just like strolling in the African prairie, there is no danger to come to them in an instant ... Front, from TVB and love A TV series "Blind Lawyer" produced by Qiyi jointly produced a lot of people's concern about blind. However, it is not only blind, and the deaf people are the same when they go out.
Although they may have a pair of eyesight, because of the auditory obstacles, even in the colorful world, they also face a lot of quiet dangers like blind, slightly do not pay attention, It is easy to hit an accident.
According to the World Health Organization, about 360 million people in the world have hearing obstacles, but also, there are many people who are prone to danger in this way.
If there is a set of equipment that can be carried with you, you can help these auditory obstacles to distinguish the direction of sound, perhaps minus danger. It is exciting that recently, a group of students from Singapore technology and design university have turned this idea into reality.
They made a glasses named Peri, which can convert the surrounding audio into visual effects to remind the audible obstacle, which direction is coming from.
This device is equipped with four microphones to connect around the glasses. At the same time, the auditory obstacle can also adjust the sensitivity of the microphone according to its own situation, and the light will correspond to the maximum sound source. In the advanced version, this glasses also have the light sensor to automatically adjust the brightness of the prompt lamp according to the ambient light.
It is understood that their inspiration source game. If you have played the FPS type game, such as "Watching Pioneer", you may notice: When you are attacking by the enemy, there will be red rays to remind players, you are being attacked in which direction.
It is based on this principle. When the glasses detect the surrounding sound, it will immediately turn into the light of the corresponding direction to remind the deaf. So just bring this pair of glasses, the auditory obstacle can basically know that someone may say in which direction is coming over.
Although this glasses are still in a simple prototype stage, its design is not bad, gaining the National Championship of James Daisen Design Awards in Singapore, and will enter the international group in Singapore in October.
Pavithrenre, the head of the team, said that they would like to make it into accessories, allowing it to adapt to most of ordinary glasses to reduce the cost of use of auditory obstacles.
At this stage, PERI is facing some problems. For example, the shape is not streamlined, and the effect implemented in the noise environment is not particularly ideal. However, pavithren said they are adjusting the audio algorithm of the system, hoping that it will make it perfect.
I hope that more and more inventions can make this world less unfortunate, more than one.
