Engineers have found a universal way to control a “smart” column using ultrasonic waves. The corresponding article was published in the journal IEEE Transaction on Emerging Topics in Computing.

According to dni24.com, important research in this area is carried out by specialists in order to correct all inaccuracies and malfunctions in the "smart" technique. Then you can update the software and not worry about minor problems. Engineers from Waseda University have created a device design that will allow you to emit ultrasonic waves with pre-set voice commands. As you reach the column, the necessary audio signals will be loud, so that the user of the device will be able to hear interference.

It is worth noting that the technology that will be used for smart speakers is also applicable to the smart home system. Moreover, it will allow you to manage other devices that have access to personal user information, including map data.
