Blind Stick Alert Alarm

Age Group 8+

Do you know which country has the most blind population? Unfortunately, it’s India. Blind individuals are off guard when they travel since they don’t get enough knowledge about their area, and that increases their chances of a collision. 

Can technology help to solve this challenge? The answer is Yes! You can build a Blind Stick Alert Alarm to help blind individuals steer away from any obstacles in their path. This stick is able to detect the distance between an obstacle and alert the visually impaired people with a buzzer alert. Now, as sometimes in hearing these voice alerts are quite impossible in crowded places and noisy environments. So, the product also has the ability to provide vibrations along with a buzzer. This ensures the alerts are communicated to the visually impaired person properly.

How Does it Work?

Visually impaired people find difficulties detecting obstacles in front of them during walking in the street, which makes it dangerous. The smart stick comes as a proposed solution to enable them to identify the world around them. 

This Smart stick will have an Ultrasonic sensor to sense distance from any obstacle, LDR to sense lighting conditions, and an RF remote using which the blind man could remotely locate his stick. The stick is capable of detecting every type of obstacle in the range of 4 meters during 39 ms and gives a suitable message empowering the blind to move twice his normal speed because she/he feels safe.
