C2.15
Touch Sensing Principles and Failure Conditions
Cards in this group · 4
- C2.15.1Capacitive touch depends on finger conductivity, so most insulating objects cannot trigger it
- C2.15.2Resistive touch conducts through pressure deformation, works with any object, but needs more pressure
- C2.15.3Optical and ultrasonic sensing has lower recognition rates in bright light or water films
- C2.15.4The touch sensing principle determines whether pens, knuckles, and other substitutes trigger a device
