We often look at an object or surface in our home such as a wall or book or back of our phone and wonder that what would happen if they were Touchscreen.
This dream has been come true by the researchers at Carnegie Mellon University in form of Electrick which uses software and a spray in order to turn your surfaces smart.
This technology works with the help of an algorithm in order to read the press of our finger by sensing changes in the flow of electricity across the conductive surface.
According to the researchers, this is the first time when they are able to take a can of spray paint and put a touch screen on almost everything. This Electrick can consider the impact in which when our finger touches any touchpad, then it releases a small amount of electric current to ground.
The idea which is being used by the Electrick is called electric field tomography, running small amounts of current sequentially with the help of electrodes in pairs and recognizing any voltage differences. It means that this Electrick can struggle with the accuracy but is has a lot of potential.
The researchers were able to make the surfaces as large as a 4-by-8-foot sheet of drywell along with objects like a steering wheel, the surface of the guitar as well as a Jell-O mold of a brain into the Touchscreen. The idea of the researchers is to create an interactive back of a smart phone.
