How does a glass screen know exactly where your finger is?
Trying to tap your phone with winter gloves on and it ignores you — then bare-finger and it works instantly. Also a rain-wet screen tapping itself (ghost touches) on a drizzly day.
Talk about it
- Guess first: does the screen feel your press, or sense something invisible about your finger?
- Why do special winter gloves work on phones when regular ones don't? What's different in the fingertips?
- When the screen taps itself in the rain, what do you think the water is doing to the grid?
