Alert assistive device for maintaing the minimum physical distance

The coronavirus pandemics changed people's social life. The lockdown aimed at preventing the spread of the SARS-Cov-2 virus was and still is a temporary solution. On the one hand, human nature itself urges us to be in contact with each other, while, on the other hand, people need to move from one place to another and to interact physically with other persons in order to fulfil vital needs. This is why certain precautions are necessary to avoid catching the virus or transmitting the disease. It is recommended to keep a minimum 2-meter distance from other persons, to wear a mask covering nose and mouth, to use hand sanitizer etc. This paper presents a device intended to warn the person wearing it about maintaining a safe distance from other persons.
