Touchscreen user interfaces configured to detect a finger flick touch gesture for controlling software applications, computers, devices, machinery, and process environments. Such user interfaces can be manipulated by users and provide a wide range of uses with computer applications, assistance to the disabled, and control of electronic devices, machines, and processes. Enhancements can include velocity and pressure sensing capabilities. The touchscreen can be realized with a transparent touch sensor array positioned over a visual display. Dynamically assigned labels can be provided by the visual display. Multitouch capabilities can be included that are responsive to additional contact, for example by other parts of a user hand. Displayed visual content, including visual content selection, motion, and sizing, can be controlled by a finger flick gesture. Finger movement trajectories can be tracked, and pluralities of control parameters can be associated with the finger flick gesture.
