Watch Your Hands

Using a combination of depth cameras and computer-vision algorithms, a research team has tracked people around two hospital wards and automatically identified when they used gel dispensers to wash their hands. The trial was so successful that the group is now going to fully kit out three hospitals for a whole year, to see if it puts a dent in the acquired infections. Jeff and Anthony discuss the practice of washing up, and whether cameras or people are better at staying vigilant.
