The technique creates a touch surface on furniture

With only a paint sprayer, US researchers can create touch-sensitive surfaces such as smartphones on the walls or tables.

Scientists at Carnegie Mellon University in Pittsburgh, Pennsylvania, have introduced Electrick technology capable of creating touch surfaces on the interior, instrument just by spraying, according to Livescience.

Electrick technique uses electrodes attached to the object to determine where the point of contact occurs.

The condition for creating induction surfaces is that the objects must be made of conducting material or coated with a conducting layer . Electrick technique uses electrodes attached to the object to determine where the point of contact occurs. While not as accurate as the smartphone's touch technology, homemade touch surfaces still allow researchers to perform basic commands.

"This technology is very similar to the way touchscreens work," said Yang Zhang, a PhD student at Carnegie Mellon University's Human Computer Interaction Institute. "A part of the electricity will be transmitted to the ground when the human finger touches an electric field." By finding the point where the transmission takes place, we can find where the user touches the surface. "

"The goal of this technology is to turn everything into a touch sensor ," Zhang said. "Touch technology has been very successful. This is a simple way to interact with computer resources . " Zhang said that the surfaces using Electrick technique are very durable and can be protected by a coating.

The touch screen of the smartphone is made of expensive materials, using complex and expensive techniques. According to the researchers, the less expensive Electrick solution can be used for educational, entertainment or other commercial purposes.
