IIT-KGP researchers develop AI-based system to track social distancing

The team, under the leadership of professor Debashish Chakravarty and professor Aditya Bandopadhyay, has engineered a low-cost device which can detect the gap between individuals, a spokesperson of IIT-KGP said.

A group of researchers at IIT- Kharagpur has developed a cyber-physical system based on artificial intelligence for monitoring social distancing in public places, an official said on Saturday.

The team, under the leadership of professor Debashish Chakravarty and professor Aditya Bandopadhyay, has engineered a low-cost device which can detect the gap between individuals, a spokesperson of IIT-KGP said.

"The device will play a proximity alert sound through audio output, whenever any violation of the social distancing norms occurs. It captures images of the field view and computes the distance as per criteria set by the Ministry of Health and Family Welfare," a member of the research group said.

The researchers had focused on the ease of deployment of such a device in remote places and curtailing the cost by using inexpensive and easily accessible hardware materials, he said.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

Students have come up with the device leveraging readily-available hardware while the lockdown was in place, the spokesperson said.

The system has been successfully tested by installing three prototypes of the device within the IIT-Kharagpur campus.
