Japan's Fujitsu Ltd has developed an artificial intelligence monitor it says will ensure healthcare, hotel and food industry workers scrub properly, Reuters reported.

Fujitsu's AI checks whether people complete a Japanese health ministry six-step hand washing procedure that like guidelines issued by the WHO asks people to clean their palms, wash their thumbs, between fingers and around their wrists, and scrub their fingernails.

The AI, which can recognise complex hand movements and can even detect when people aren't using soap, was under development before the coronavirus outbreak for Japanese companies implementing stricter hygiene regulations, according to Fujitsu. It is based on crime surveillance technology that can detect suspicious body movements.
