This is a simplified experiment for the beginner and to get you started on the series set.
What you’re testing
How modern devices detect human conductivity rather than pressure.
Materials
- Smartphone or tablet
- Finger
- Gloves/fabric (optional comparison)
Method
- Use the phone normally with your finger
- Try the same actions with a glove
- Compare responsiveness
- Try different materials
What you will see
- Finger interacts normally
- Gloves often fail
- Different materials behave differently
Why it works (simple explanation)
The screen detects changes in an electrical field caused by conductive contact.
