COVID 19: Smart glasses can take your temperature from 1 meter away, and thus detect people who have a fever, one of the main symptoms of coronavirus.
Security forces in China wear smart glasses that work with AI to detect people with a fever.
The glasses use a thermal imaging camera to measure the temperature of someone up to 1 meter away.
The glasses were made by AI startup Rokid, which claims that each set can control the temperature of several hundred people in just two minutes, according to a Publication of the South China Morning Post.
When devices detect someone with a fever, they send an automatic alert to security personnel and create a digital file.
The standard was set by security guards at Hongyuan Park, part of a wetland in eastern Hangzhou. The park is public and is one of the first to reopen as virus infections begin to decline.
Rokit reports that since January, many models of smart glasses have been made available to the public security office and the Hangzhou police. According to the company they have also been distributed to the authorities of the nearby cities Huzhou and Quzhou.
Snowden: pay attention to the measures for the coronavirus
Of course, there are many companies that try to detect COVID-19 with thermal imaging systems. The product sells as there are too many stakeholders: hospitals, airports and even brothels use the devices to control their customers, staff and patients.
But this does not mean that technology is always effective.
The devices measure skin temperature, which is not always the same as body temperature. They can also make too many mistakes (pdf). The most important thing, of course, is that they cannot detect infected people who do not yet have symptoms.
The journal Science he says that eight passengers who recently flew from Italy to Shanghai tested positive for COVID-19 and were not identified by airport checks.
