Methods of identifying touched areas have been wiped properly

ABSTRACT

According to the CDC, COVID-19 most commonly spreads during close contact. Although the cleaners are disinfecting the public places where they are expected to have been contacted, it is still difficult to know exactly which areas have been touched and wiped out. We devised combined methods of detecting touched and wiped areas by people, using both thermal and imaging cameras. It detects the changes of temperature when people touched or wiped in about 3 seconds. To improve the accuracy, we utilize object recognition for humans from imaging cameras as a method of filtering. All marks are tracked and calculated, to disclose which areas are still remaining as touched areas, revealing the information to anyone who wants to know. © 2021 ACM.
