• Device CameraGives your Lens the camera picture, live or frozen as a still. Your Lens can show that picture on a surface, or keep the still to use later.
• Face EventsMakes your Lens react when you open your mouth, smile, kiss, raise your eyebrows or tilt your head. It also tells the Lens where your eyes, nose and mouth are on screen.
• Face MLChanges your face with one ready-made effect, for example an anime look, a meme grin or a skull. Say the look you want, and your Lens keeps that one effect.
• GyroscopeTurns tilting and shaking your phone into a control for your Lens. Ask for a tilt game, for example a maze where you roll a ball to the exit.
• Hand TrackingFollows your hands and reads gestures like a fist, a pinch, a thumbs up or a peace sign. Ask for something your hand controls, for example drawing with a pinch.

• SoundPlays a sound in the Lens. Add the sound you want, and the Lens can start it, pause it and resume it.
• Touch EventsAdds tap, drag and swipe controls, so you touch the screen to control the Lens. Say what each touch does, for example tap to drop a coin.
