Unlock device using facial recognition and go to Homescreen

I have a Samsung Galaxy S4 running Android 5.0.2 stock, and I'd like to use the facial recognition in addition to drawing an unlock-pattern. This works fine, my face is recognized, but after that, only the dots of the unlock-pattern disappear, meaning I still have to swipe the screen in order to get to the home-screen (where the icons are). I'd like to go to that screen directly when my face is recognized, without the swipe-part. So what's the clue getting rid of that? If I have to swipe, faciol recognition is useless in my opinion, because if I swipe the screen or if I swipe a pattern makes no real difference. So how is this intended to work?
