This Spray Can Make Your Wall a Touchpad
Electrick combines conductive coatings or additives with electrodes and algorithms
developed at Carnegie Mellon University.
It can create a touchpad on just about any
surface—walls, steering wheels, toys—to control lights and other devices.

1.
Setup
Electrick’s spray primes a surface to better conduct electricity, and low-voltage electrodes
placed around the perimeter of the area can register changes in the current caused by
touching the surface in a particular spot.
2.
Use
Users can control devices by touching the sprayed area.
For example, the body of a guitar
can become the equivalent of several effects pedals.
