Hongyuan Park, part of the reserve of the Xixi Wetland in Hangzhou City, security personnel have begun using augmented reality glasses of the startup Rokid. They are glasses that at first glance seem like the sunglasses, but they have a large thermal camera on one side that makes it clear that they are not just simple glasses.
According to the South China Morning Post, the goggles can check the temperature of hundreds of people in minutes. So they help monitor improvements to the park’s trails. In addition to checking the temperature, they are also able to perform facial recognition. It helps in having a digital record of citizens.
On the other hand, the manufacturer recently shared some more details about the glasses. They say they are ideal for operating in airports, subways, shopping malls, and other public spaces. They also explain that they can measure body temperature at a safe distance of two meters to avoid physical contact. As for speed, they say they do the task in half a second. Thus exceeding the two seconds of infrared thermometers on the market.
Thermal scanning is an effective method of detecting people with above-average body temperature. It does not detect people who may be infected but have not yet developed symptoms.
One of many measures to combat COVID-19
The Asian media South China Morning Post says that they have provided Rokid’s glasses to security officers and highway police in Hangzhou, Huzhou, and Quzhou.
Apart from these smart glasses, China has used other methods as well. They are using massive nationwide facial recognition and surveillance networks. They monitor citizens and identify which of them are infected with the coronavirus. An example of this is how they have assigned a color QR code to each citizen on their mobile. This QR code indicates whether or not they are allowed to travel and where they can do so.
