As the spread of the new coronavirus continues, a service has been launched that uses digital technology to "visualize" the risk of infection at restaurants and encourage them to visit during safe hours.
This is a service that Hitachi, Ltd. and others started on the 3rd, and sensors installed in restaurants detect the concentration and sound of carbon dioxide in the store, as well as the radio waves of smartphones.
As a result, in addition to knowing the congestion status, humidity, noise, etc. in the store, the concentration of carbon dioxide is displayed in three stages: ``good'', ``needs some ventilation'' and ``needs ventilation''.
This information can be viewed by customers on the Internet, and the aim is to "visualize" the risk of infection and inform them of the situation in the store so that they can visit the store during low-risk hours.
Izumi Tamada, general manager of a commercial facility in Tokyo that introduced the service, said, "We want customers to come to the store with peace of mind by correctly communicating that it is safe."
Shingo Hane, General Manager of Hitachi's Managed Service Division, said, ``I wanted to help restaurants that are particularly in trouble.
Regarding infection control measures at restaurants, Toshiba has also started a service that monitors and displays the concentration of carbon dioxide in stores in collaboration with electronic equipment manufacturers in Tokyo, and efforts to "visualize" the risk of infection are spreading.
