This question's explanation and your answers so far.
問 59
Incorrectア
“Touch typing” refers to a typing technique (blind typing) in which one strikes keys using only the positional sense of the fingers without looking at the keyboard; it has nothing to do with simultaneous multi-point contact on a touch panel.
Incorrectイ
“Double click” is the action of pressing a mouse button twice in quick succession. It is a sequential operation along the time axis, not a method of touching multiple points simultaneously.
Incorrectウ
“Multitasking” is a term for an OS function that runs multiple processes (tasks) in apparent parallel on a single computer; it is not an input method.
- エ
正解 Choice エ, “Multi-touch,” is correct. Multi-touch is an input method that simultaneously detects contact at multiple points (multiple fingertips) on a touch panel and operates the device by combining the positions and movements of those contacts. Typical examples include pinch-out, spreading two fingers apart to zoom in, and pinch-in, bringing them together to zoom out; it is the technology that supports the intuitive operation of smartphones and tablets. This exactly matches the question’s description of “touching multiple points simultaneously to operate.”
- Multi-touch = an input method that detects simultaneous contact at multiple points on a touch panel to operate the device (pinch-in / pinch-out are typical examples).
- Distinguishing it from confusable terms: touch typing = blind keystroking, double click = pressing a mouse button twice in a row, multitasking = parallel execution of multiple processes — all different concepts.
