AI cameras detect when hospital staff don't wash hands

When patients go to the hospital to get treated for an illness, sometimes they end up far more sick than they were when they entered. In an effort to improve hospital hygiene standards and reduce the incidence of these infections, researchers have developed an AI camera-tracking system that automatically identifies when staffers and patients use hand sanitizer dispensers. The proposed vision-based smart hospital. The Yellow polygons indicate areas covered by the sensors. Researchers based at Stanford University and the Swiss Federal Institute of Technology in Lausanne conducted a trial of their system using depth cameras and computer-vision algorithms.
