Resumen de Smart Walls.
The article focuses on the use of conductive paint to convert a wall into a track pad and motion sensor. It states that the surface was created using painter's tape applied in a lattice pattern and then coated in a conductive nickel paint, before the tape was removed to create a pattern of electrodes connected through thin copper tape strips. It mentions the wall could track touches or gestures similarly to smartphone screens and detect users within three feet of the wall.
