Imagine you can turn on a light just by touching it! That's what touch sensors do. They can tell when something is touching them. We can explore this idea with a simple game using our hands and some friends. This activity will help you understand how computers sense touch, even though we won't be using any computers at all!
In this unplugged activity, we'll explore how touch sensors work by mimicking them with our bodies. One person will be the 'sensor,' and another will 'touch' the sensor. The 'sensor' will react when touched, just like a real touch sensor would!
Match the word with its meaning:
| Word | Meaning |
|---|---|
| 1. Sensor | A. Something that feels a touch |
| 2. Touch | B. A signal that tells something happened |
| 3. Signal | C. To come into contact with something |
| 4. Input | D. Information going into the sensor |
| 5. Output | E. Information coming out of the sensor |
Match the correct letters (A, B, C, D, E) with the numbers (1-5).
A ______ is like a special helper that can feel things. When you ______ the sensor, it sends a ______. This signal is an ______ that the sensor uses to do something, like turn on a light or make a sound. The light or sound is the ______.
Can you think of three things in your house that use touch sensors? How do these sensors make your life easier?
