Fujitsu Modifies Actlyzer to Check for Proper Handwashing

Fujitsu has developed a new gesture recognition solution that can be deployed to make sure food service employees are observing proper protocol when washing their hands. The solution is based on the company’s Actlyzer technology, which was trained with a data set of 2,000 hand washing videos featuring different people, camera positions, and types of soap.

Fujitsu refined Actlyzer in response to COVID-19, and in anticipation of sanitary regulations that are expected to go into effect in Japan in 2020. The new law will require food service workers to follow the six steps of proper hand washing, as established by the Japanese Ministry of Health, Labour and Welfare. At the moment, the confirmation process is carried out through self-report or manual observation, both of which take time and are prone to human error.

The Actlyzer, on the other hand, will automate that process, and negate the need for manual hand washing oversight. The system will record the hand washing process, and notify the employee when they have completed each of the six official steps. The results will be displayed on a screen to allow the employee to track their progress.

The system recognizes the shape of two hands together, rather than the shape of each individual hand. It can also tell how many times people have rubbed their hands while washing. Actlyzer is 95 percent accurate when applied to the six steps, and 90 percent accurate when determining the number of hand movements, Fujitsu says.

While the technology was developed specifically for the food service industry, Fujitsu believes that it will have similar applications in other sanitary environments like schools, hotels, and medical facilities. The company noted that COVID-19 has made people more conscious about the public health benefits of hand washing and could lead to stricter enforcement measures.

Fujitsu is also the developer of the contactless PalmSecure authentication solution, which was recently integrated into IGEL OS.
