Here are 6 advanced technologies that help blind people move - Blindness is a general term used for the condition of someone who is experiencing a disorder or obstacle in his sense of sight. Due to the reduced function of the sense of sight, blind people try to maximize other sensory functions such as touching, smell, hearing and so on so that not a few blind people have extraordinary abilities such as music or science.
According to data from the World Health Organization (WHO), the number of blind people in the world in 2017 reached 253 million. This number is predicted by Lancet Global Health to continue to increase threefold by 2050. Several technological innovations were created to support their daily activities, because they know the blind population is not small. This time, Teknologi.id will discuss 6 advanced technologies that can help the activities of everyday blind people. Here's the list:
Augmented Reality
For the visually impaired, the dream of seeing the world is not impossible in the near future with the improvement of Augmented Reality technology. Researchers at Oxford University in the UK use AR to help improve the visibility of people with visual impairments.
The technology is installed in smart glasses called "OxSight" which is able to draw the weakest point of one's vision. At present, the size of the smart glasses is still large enough that it is still rather striking if used daily. But the researchers promised the final product would be more like ordinary glasses.
Braille letter translator
Technology also helps those who have special needs to read normal letters to Braille. Braille letters are letters made with tactile systems intended for people with visual impairments. arising codes that are now known to help blind friends are named after a French man born January 4, 1809, Louis Braille.
Researchers from the Massachusetts Institute of Technology, USA are trying to develop a tactile letter system to a device that can translate ordinary letters into braille in real-time. This device will be equipped with a scanner feature. Its function is similar to that found in many translator machines, namely capturing images written in ordinary letters, then translating them into braille.
Indoor Navigation Technology of Sound Objects
"Seeing I App" is provided by Microsoft for the blind. But researchers from the California Institute of Technology make use of Microsoft's HoloLens to guide blind people in complex indoor buildings. They combine sound and room observations and 360-degree objects in real-time. The tools they develop can help to find certain objects or guide them through the paths that have been pre-set.
"Subtitles" Braille letters
As you get older or older, the harder it is to learn braille, this project helps those with visual impairments. This braille letter called "ELIA Frames" helps new blind people to adapt more quickly to braille. This discovery is also useful for those who want to learn braille quickly and easily.
Wearable Device Hazard Marker
Wearable devices that will tell blind people if there are obstacles when walking and are used to give direction to the user if there are disturbances or obstacles around him, especially when walking. The device developed by the VTT Technical Reseacrh Center from Finland is nicknamed Guidesense.
Guidesense relies on millimeter-sized radar sensors to detect even the smallest obstacles, such as a twig of twigs that are shifting. This box-shaped tool is placed at the bottom of the chest, right in the area around the pit of the heart. In the trial, the researchers claimed 92 percent of users felt helped by Guidesense, while 80 percent felt more confident walking around on their own with this tool.
Eye "Bionic" and "Bioprinting" Three Dimensions
This technology can be the newest among the previous lists. Researchers from Newcastle University in the United Kingdom mix stem cells with algae molecules into biological ink. Then the ink becomes the main ingredient for three-dimensional artificial cornea printing.
This tool can restore some of the patient's vision. All of the above technologies are expected to be used more widely for blind people around the world. Similar findings were also developed by the company VisionCare, which has developed a replacement for ordinary eyeball lenses, namely "Implantable Miniature Telescope".
