New 'stick' for visually impaired people
Visually impaired people use a stick to guide their way, but sometimes they get into accidents due to their miscalculations. Now scientists have created a device that will navigate their way 100% accurately

See Visually impaired people have to take the help of sticks or guide dogs to walk, but now they don't have to do that. Scientists have created a special device called 'Shesh' for this, which can be very helpful for visually impaired people in navigation. With this, they can easily locate things. 'Shape' based on virtual reality can bring revolutionary changes in the mobility of visually impaired people.
On the concept of touch
A human can easily feel any shape by touching it with his hands even with very little concentration. He does this work very easily. On this concept, scientists of Imperial College London have prepared this special device 'Shape'. This device developed by scientists Dr. Ed Spiers and Charity Bravo Victor works on 'haptic perception' just like our hands, the way people get information about objects through touch. This torch-shaped device bends to understand where the person has to go next and whether he is going in the right direction. If the user is going in the right direction, it becomes motionless.
Beyond vibration Till now vibration has been used to understand things through touch, but Shape is based on technology beyond this. According to scientists, this device Udi works on virtual reality and is very easy to learn and use. During the study, it was also seen that 'Shesh' gave better results than vibration. In vibration technology, everything depends on hearing. In this, you get indications based on the vibration pattern as to which way to go or where to turn, but a mistake in hearing can prove to be dangerous. Also, after listening to vibration for a long time, a person starts getting irritated and gets distracted and is not able to hear properly. This affects his ability to walk, which often creates problems.

Scientists included 10 blind and 10 normal people in the study. They were given tasks in indoor premises. It was seen that after using 'Shesh', there was no difference in the walking ability of blind and normal people. Also, their walking and observation speed was also seen to be much faster. Now scientists are also testing its effect in other aspects, especially how it works in open environment and changing weather. Along with this, scientists are also working towards making it available to common people by the end of 2025, so that the path of the visually impaired can be made easier.
