With Double Tap you can operate Apple Watch 9 without touching the screen

During his recent Wonderlust eventApple has unveiled the upcoming Apple Watch Series 9, and with it an ingenious new way to control the wearable called Double Tap.

This feature allows users to perform the “most common actions on (their) Apple Watch Series 9” by simply tapping their index finger and thumb on one hand twice quickly. You don’t even have to touch the screen. As seen in the official announcement trailer, the gesture can be used to turn off alarms, set timers, answer calls (or end them if you’re too loud), and even take photos via the Camera Remote feature. Apple goes further states in his post that using Double Tap on the watch face opens the Smart Stack and tapping again allows you to scroll through individual widgets.
