Visualizing touched places for Corona prevention

Touched places detection using heat traces by thermography

Visualizing touched places for Corona prevention

One effective infection prevention method is regularly disinfecting the environmental surfaces of public areas. However, no method currently identifies where and how much others have touched a particular door or shelf. This exhibition introduces a visualization system that identifies touched places by overlay projection. When a person touches an object, her hand’s heat remains on its surface. This heat trace can be captured by thermography cameras. By combining Near Infrared (NIR) and thermography cameras, we can detect the touched places with a light algorithm. This technology enables us to identify the objects or places that others have touched, although the virus itself remains invisible to the naked eye. We believe that our system will help relieve anxiety during the COVID-19 pandemic. It will also enable us to gather statistics and data about the places touched by people and improve the efficiency of disinfection activities.
