Forget about a smart speaker, you may soon be able to control your smart home with a few clicks on your wall. Researchers at Carnegie Mellon University and Disney Research have developed a method to make your walls smart for $ 20 per meter, as described by NBC News.
Dubbed Wall ++, the researchers found that they can use conductive paint and a custom sensor board to create electrodes and convert a standard wall into a gesture recognition touchpad and an "electromagnetic sensor for detecting and tracking electrical equipment and devices Devices".
The system could potentially monitor activity in rooms and automatically adjust the light level of a TV set on or off, or send a warning when a device goes out. The Wall ++ could also track people carrying certain electronic devices that emit an electromagnetic signature.
This is not the first time that Carnegie Mellon researchers have found a way to turn an analog surface into a touchpad. Last year, researchers at the university announced a system called Electrick that allows you to spray conductive inks on smooth surfaces to enable touch controls.
There's still plenty to do, the Wall ++ has not been optimized for power consumption, and there's probably going to be a simpler way of installing it than a sensor board on the baseboard, but overall functionality seems to be sounding. Get ready, stop yelling at Alexa and start beating your wall.
