“The Xbox One, you see, can recognize you from the others in the room. And, it can track up to six people in the room at a time! It can track whether you’re actively watching the TV, whether you’re watching or just have it on while you’re doing other things. It can tell your reaction to what you’re watching by looking for smiles or grimaces. It can even measure your pulse to see how the show is causing you to react. And, it can do all this in a room completely in the dark. And it can do this for six of you at a time.”
