Most people touch their faces unconsciously, for instance to scratch an itch or rest one's chin in hands. To reduce the spread of novel coronavirus (COVID-19), public health officials recommend against touching face, as virus is transmitted through mucous membranes mouth, nose and eyes. Students, office workers, medical personnel on trains were found between 9 23 times per hour. This paper introduces FaceGuard, a system that utilizes deep learning predict hand movements result provides...
