One of the acclaimed new features of the S4 is Smart Pause, which automatically pauses video playback when the user looks away from the screen.

Like all good "Life Companions," the S4 wants the attention it deserves—when it's talking to you, you'd better be looking!

It wasn't long after we started playing with Smart Pause for ourselves that we knew we'd have to find a way to trick it...

The S4 was reluctant to recognize our Iron Man poster or our office Chia Gnome as human faces, but in the end we managed to find a way to fool it.
