Summary	To support COVID-19 social distancing measures, the "1.5 meter monitor" system was developed for public spaces within the Amsterdam-Amstelland Safety Region. This system uses a camera, a computer with a GPU, and a screen to remind individuals to maintain a 1.5 meters distance by displaying their image overlaid with color-coded smileys—green for over 1.8 meters, orange for 1.5-1.8 meters, and red for less than 1.5 meters. An audio alert may also be played. The system does not store visual data or recognize individuals, only counts the number of people within camera range. It operates under a temporary legal framework linked to the COVID-19 Emergency Ordinance, and its effectiveness is evaluated through qualitative interviews.

Description

Because of COVID19 measures have been taken to prevent person to person detection, one of the most influential and important new regulation is to keep 1.5 meters distance from each other. To help remind citizens to maintain this distance we have created the 1.5 meter monitor.

The 1.5 meter monitor is a system created to make users aware of social distancing measures. It uses a camera, computer with GPU (or edge devices) and a screen to create awareness for anybody within the field of view of the camera to keep social distance. It does so by displaying a picture that is taken of passersby, that is overlayed with a smiley: a green smiley for more than 1.8 meters distance, an orange smiley for 1.5-1.8 meters distance and a red one for less than 1.5 meters distance. An audio signal can also be played.

The system does not store any visual information, and when detected people will be displayed with a smiley overlay to prevent visual recognition. We do record the number of passers-by within range of the camera, to monitor whether it is too busy in a certain area.

We are using the 1.5 meter monitor temporarily because of the COVID-19 Emergency Ordinance and because of the need to keep a distance of 1.5 meters. The system is being tested in public spaces at a number of locations in the Amsterdam-Amstelland Safety Region.

This is a low-risk algorithm. None of the images are stored for later use. To measure the effectiveness of the 1.5 meters monitor, qualitative interviews will be conducted.

The chairman of the Amsterdam – Amstelland Safety Region decreed that the 1.5 meters monitor should be linked to the presence of the Emergency Ordinance COVID-19 and / or the necessity of keeping a distance of 1.5 meters in formal legislation. As soon as the Emergency Ordinance COVID-19 is withdrawn and / or keeping a distance of 1.5 meters is no longer necessary on the basis of formal legislation, the legal basis under the 1.5 meters monitor will be removed.
