I'm currently using the Xbox One controller.
The left and right analog sticks control your left and right hand respectively and you use the left and right triggers to activate your selection.
Your hands/fingers snaps to the options as you move the analog sticks.
Works quite well, but probably not as intuitive as the touch controllers.
Update: Setup my Leap Motion to work with the game, now I can wave my hands about like everyone else and point at people. Not much use for controls in the game though, too inaccurate.
But at least you can switch between hand gestures and Xbox One Control by simply pressing A or B
