How does the "Halo Back" smart screen protector work?

[Jerry®]

Have any of you seen this? It's called the Halo Back Smart screen protector that puts an invisible virtual back button next to the home button on an iPhone 6/6Plus. I can't figure out how it works? Seems handy tho....

Halo Back Smart back button

"Halo Back is the first smart screen protector in the world. The invisible back button let your iPhone go back easily. With this little magic, you can operate your phone with a single hand."

Must be some sort of conductive layer connecting your touch from the bottom "back button" to a real back button image on the screen?

How does it work? It’s pretty cool actually. The iPhone’s capacitive touchscreen display knows what we want it to do by reading where our fingers distort its electrostatic field. Halo simply uses a circuit layer to re-route that current, allowing your lower left touch to register in the top left corner.

Did anybody else see this and think of the Gwen Stefani song, "Hollaback Girl?"
