触摸屏如何区分点击、滑动与双指缩放手势

Capacitive touchscreens detect finger contact by measuring tiny changes in electrical field distribution.
A single tap registers as a brief, localized capacitance spike at one coordinate point.
Swipes are identified by tracking continuous coordinate shifts across multiple sensor nodes over time.
Pinch gestures require simultaneous detection of two distinct contact points moving closer or farther apart.
Advanced algorithms filter out accidental touches using pressure duration and motion velocity thresholds.
Some screens even analyze finger surface area to differentiate thumbs from fingertips.
Gesture recognition relies on microsecond-level timing precision between electrode row and column scans.
Machine learning models trained on millions of user interactions refine accuracy across device sizes.
This same principle enables palm rejection and stylus compatibility in modern tablets.
All processing happens locally on the display controller—no cloud dependency is needed.
