Touch is a research project that’s exploring NFC, or Near Field Communications. NFC is kind of like the technological “glue” that allows connections between various mobile devices and physical objects.
One of the areas Touch is looking at is how to make invisible wireless signals visible to gather a deeper understanding about them.  On the Touch blog, they’ve posted a gallery of images visualizing the existence of wireless signals with white dashed lines.
