Watch this video to see how it works:
A combination of motion tracking technology and computer directed lasers show a lively interplay of lines on the floor, depending on people’s presence. This way, people can move safely through public spaces such as: train stations, airports, museums, shopping malls, etc.
Here are a few visual application examples: by using circles, the one-and-a-half meter zones can be shown around multiple people. While another way is to show the absolute distance in between two people by using lines. The software is under own management and will be widely available soon.
Here are some limited details on the system: https://jolanvanderwiel.com/projects/smart-distancing-system/experiments/smart-distancing-system/
