The Federal Communications Commission has just unveiled a new Google nest thermostat, suggesting it may be equipped with a soli sensor that supports gesture control. Although it has been several years since Google last updated the nest thermostat product line, competition in the smart home device market has continued to emerge during this period. For example, through networking and machine learning technology, the system can learn family behaviors and patterns, then actively adjust the indoor temperature, and remote control through mobile app / smart speaker. < p > < p > David zats shared Google’s new submission to the FCC on twitter. Although the public information has been cleaned up, the test report still reveals some interesting changes, especially the soli sensor technology that was introduced on the pixel 4 smartphone. According to the report, the thermostat is g4cvz, which supports 2.4/5ghz dual band Wi Fi, low-power Bluetooth and 60GHz radar. Although the latter function is not mentioned, it is not difficult to guess that it is related to project soli. < / P > < p > on pixel 4, an Android smartphone, the SOI sensor embedded in the top of the screen can be used for gesture recognition. < / P > < p > for example, by tracking the movement of the hand, users can easily adjust the volume. This is similar to the camera based gesture tracking system, and may even be supported by privacy advocates. < / P > < p > unfortunately, project soli never took off as Google expected. Even after the pixel 4 was launched, the sensor has not been allowed to be used in many market regions, and the pixel 4A model released earlier this year has not been exempted. < / P > < p > as for the new nest thermostat, it is expected that users can directly wave their hands to adjust the temperature without calling on Google assistant intelligent voice assistant. Of course, you can still control it remotely through the app on your mobile device. Spontaneous combustion at a Guangzhou Motor vehicle intersection and other traffic lights in Shenzhen
