It is recommended to take a certain distance called social distancing to prevent the spread of Corona 19 infection. The social distance to prevent infection is usually 2m, which is the distance between reaching each other and in fact, it is difficult to keep exactly 2m. For this reason, Google has developed Sodar, a tool that allows you to check a distance of 2 meters around you.
Soda is an augmented reality tool that displays a 2m radius around itself through the smartphone camera screen. In fact, since you can visually check the distance to other people, it can be convenient when you are in a line in a procession where it is difficult to maintain social distance. Soda is not an app, so you can use it by simply visiting the website without installing it. However, it is important to keep in mind that some devices are not compatible and that not all devices can be used. Related information can be found here .
