A specific touch motion you use to issue commands is called a ______.

The correct completion of the statement is "Gesture." A gesture refers to a specific movement or motion that a user performs on a touch-sensitive device to communicate a command. This can include various actions such as tapping, pinching, and swiping, each of which is categorized as a type of gesture.

Gestures are an integral part of user interface design, especially in mobile and touch-enabled devices, as they offer a more intuitive way for users to interact with technology. Understanding gestures is vital for utilizing touchscreens effectively, as they can facilitate fast and fluid navigation and commands without the need for physical buttons.

While "swipe," "command," and "click" are related to touch interactions, they represent either specific types of gestures (such as swiping) or actions that might not encompass the broader category of gestures. "Click," for example, is commonly associated with mouse interactions rather than touch screens. Thus, "gesture" is the most accurate and encompassing term for defining the touch motion used to issue commands.
