Master’s student Syed Rezwanul Haque and honors fourth year student Robi Karmakar have invented this device for visually challenged. Both are from Physics department of SUST.

On the occasion of “World Disability Day 2013” this electronic device has inaugurated by Professor Dr. Muhammad Zafar Iqbal who was the supervisor of the team. The team also examined the device for more than one month before the inauguration with visually impaired people of different ages.

In the inauguration program, Md. Rajib Ali Khan, the secretory of Green Dijeb Foundation Sylhet, who is also visually challenged, was also present and expressed his satisfaction and gratitude.

Visually challenged person usually needs stick to navigate the barriers but with the help of this device no stick is necessary to identify a barrier.


This device can be easily used by attaching to hand or elsewhere in the body and start shaking automatically when an object is at a distance of 75 cm. As the object comes nearer, shaking level will gradually increase.

The young scientist group wished to see the disabled person as a self contained person like others. They also urged any entrepreneur organization for the marketing of this device so that a significant number of visually challenged people can take advantage.
