The current model of “smart home” is bound to change over time, to turn into something more perfect and useful. Scientists Ming-Chu Huan and Soumyajit Mandal from Case Western Reserve University (USA) tried to anticipate this process. Their work with sensors for motion and vibrations in electromagnetic fields led to what they called the "Internet of the ears."
"Ears" in this case is a collective term, borrowing from the saying "And the walls have ears", since it is about the "smart environment" learning to constantly "listen" to the person within itself. It is not that difficult - as a conductor, our body has a noticeable effect on the electromagnetic fields around. And with the proper sensitivity, you can remotely and very accurately measure the pulse, breathing intensity, sweating, recognize small gestures, and based on these data, draw a conclusion in what state a person is, what he is doing.
If a smart home is constantly monitoring the owner, it can very effectively adjust its work to optimize resource consumption. This is already a new level - if now the system simply turns the light on and off, then in the future it will change the brightness of each light bulb by a fraction of a percent, achieving ideal lighting exactly at that point and at the moment in time when the user needs it. This will significantly reduce utility costs. The system will take into account the wear and tear of the equipment, and the financial capabilities of the owner, and the needs of other households, and the rules of the district administration.
Huang and Mandal proved the usefulness of such measurements on the example of the operation of old buildings, where the intensity of movement of people significantly changes the dynamic load on the structure. The Internet of the ears may not be able to control all the parameters of the system, but it will be able to predict the time of failure of many devices and even warn about the risk of a potential accident.
