Japan's Fujitsu brings hand washing AI to COVID-19 fight: Three months after the World Health Organization recommended singing “Happy Birthday” twice during hand washing to fight the coronavirus, Japan’s Fujitsu Ltd has developed an artificial intelligence monitor it says will ensure healthcare, hotel and food industry workers scrub properly.

The AI, which can recognize 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.
