multitouch gesture
also: gesture, touch gesture, multi-finger gesture
A touch input technique where multiple fingers simultaneously contact a touchscreen or trackpad to trigger predefined actions, such as pinch-to-zoom or two-finger scroll.
Multitouch gestures enable users to interact with Linux systems through simultaneous contact of multiple fingers on a touch-sensitive device. Rather than relying on a single touch point, these gestures recognize patterns of coordinated finger movements to execute commands or UI operations.
Common multitouch gestures include: pinch (two fingers moving toward or away from each other to zoom), rotate (two fingers rotating around a center point), and swipe (multiple fingers moving in the same direction across the screen). These are typically handled by the libinput or Synaptics driver on Linux systems.
Example: On a Linux laptop with a GNOME desktop, a two-finger pinch gesture on the trackpad zooms in or out of a web browser, while a three-finger swipe left/right switches between open windows.
