IIT Kharagpur: AI Based Social-Distancing Monitor

The Researchers of IIT Kharagpur have developed an Artificial Intelligence based cyber-physical system to monitor social distancing in public places.

Highlights

The device developed by the researchers will play a proximity alert whenever there is a violation of social distancing norms. The device captures field view and computes distances according to the criteria set by the Ministry of Health and Family Welfare.

The researchers of the institute have designed the device using inexpensive and easily accessible hardware materials.

Social Distancing

The social distancing is non-pharmaceutical prevention of an infection. This is done by decreasing contact between the persons that are infected by the disease-causing pathogen. According to WHO, when someone has COVID-19, the minimum physical distance to stay away from him is 1 metre. The same norms are followed in India as well.

Some countries follow 2 metres of social distancing and some others follow 1.5 metres. UK follows 2 metre distancing and Australia follows 1.5 metres.
