Learn in the textbookPointing and Manual Input Devices
DefinitionPointing device (ポインティングデバイス) is the umbrella term for input devices that indicate a position on the screen or convey a movement.
ExplanationThe arrow or similar marker shown on the screen is called the pointer (cursor), and a pointing device moves it to select targets such as buttons and icons. How you operate it depends on the device: you might move the body, touch the screen, tilt a lever or draw with a pen.
AnalogyLike a laser pointer that lights up one spot on a slide in a meeting, these tools tell others "where" rather than "which characters to type."
Memory hookThe English verb "point" means to indicate something with a finger. Link the name to a family of devices whose job is pointing.
