The controllers include A, B, X, Y buttons, as well as L and R buttons and a Home button. (Attachable wrist straps add more prominent L and R buttons.) Each controller has an analog stick that also functions as a button. A new, square “capture” button can be used to capture screenshots of gameplay which you can share on social media. In the future, you’ll be able to use this to capture video footage too, according to Nintendo.
Both Joy-Con controllers include accelerometers, gyrosensors, and an “HD rumble system” that adds new levels of sensitivity to motion-based gameplay. The R controller also has a motion-IR camera that can sense the shape, motion, and distance of objects in front of it.
