ITPEC IP April 2018 Question 24
Which of the following is an input method where a touch panel is operated by touching it in multiple locations simultaneously?
Explanation
Multi-touch — a touch panel that detects several touch points at the same time.
With multi-touch, the panel senses two or more fingers at once, which makes gestures possible: pinching in or out to zoom, rotating with two fingers, swiping with several fingers. Smartphones and tablets use it as their main input method.
Answer (d)
Why not others:
- •(a) Touch typing — typing on a keyboard without looking at the keys
- •(b) Double click — pressing a mouse button twice quickly at one position
- •(c) Multitasking — an OS running several tasks concurrently; it has nothing to do with touch input
Key rule: Multi-touch is about many simultaneous touch points on a panel; multitasking is about many programs running on one computer.
