Why Do Phone Screens Only Respond to Human Fingers, Not Other Objects?
Almost all modern smartphones use capacitive touch screens.
How Does a Capacitive Touch Screen Work?
Behind the surface of the screen is a conductive layer that produces a small electric field.
Because this process relies on changes in electrical charge, objects that cannot conduct electricity are unable to trigger a response on a touchscreen.
Why Wood or Plastic Doesn't Work?
Wood, plastic, paper, and most everyday objects are insulating materials that do not conduct electricity well.
This is what makes the cellphone screen not respond when touched using ordinary objects even though quite strong pressure is applied.
What About Stylus?
Not all styluses work the same.
Meanwhile, active styluses on certain devices have additional technology such as Bluetooth or a special digitizer that can provide a higher level of precision for drawing and writing.
Can Gloves Be Used?
Ordinary gloves generally block the flow of electricity from the fingers to the screen so that the touch cannot be read.
Why was this technology chosen?
Capacitive screens have many advantages over previous technologies.
This technology allows various modern gestures such as pinch to zoom, swipe, and navigation using several fingers at once.
