Computer Vision for Parents

adults teaching children aged 4–16 · 4 activities · about 15 minutes each

Print this and work through one activity at a time. Each one ends with something you can check, so you can tell whether the idea actually landed rather than guessing.

1. Become the camera

Ages 3–7 · about 10 minutes

You need: A cardboard tube or rolled paper

  1. Have the child look at the room through the tube and describe only what fits in the circle.
  2. Move the tube and ask what happened to the thing they just described.
  3. Ask whether the sofa stopped existing when it left the circle.
It worked if: The child can explain that the camera only knows what is inside the frame right now.

What went wrong / what surprised us:

2. Pixel grid on graph paper

Ages 5–10 · about 20 minutes

You need: Graph paper and two coloured pencils

  1. Fill in squares to draw a simple shape — a heart or a letter.
  2. Read the grid out loud row by row as "filled, empty, filled".
  3. Have a second person redraw the shape from the read-out alone.
It worked if: The child can explain that a picture can be sent as a list of numbers and rebuilt exactly.

What went wrong / what surprised us:

3. Break a classifier on purpose

Ages 8–15 · about 35 minutes

You need: A laptop with a webcam, Teachable Machine

  1. Train a classifier to tell two of the child's toys apart.
  2. Test it in a different room, under different light, at a different distance.
  3. Log every condition that caused a wrong answer.
  4. Retrain covering those conditions and re-measure.
It worked if: The child can name at least two conditions that change the answer without changing the object.

What went wrong / what surprised us:

4. Audit a real vision system

Ages 12–18 · about 45 minutes

You need: A phone with Google Lens or a similar app

  1. Pick twenty household objects and predict which the app will get wrong.
  2. Test all twenty and record the actual result against the prediction.
  3. Group the failures — was it lighting, angle, an unusual object, or an object type the app was never built for?
  4. Write two sentences on who would be harmed if this system were used for something that mattered.
It worked if: The teenager can distinguish a failure caused by input conditions from one caused by training coverage.

What went wrong / what surprised us:

A note on tools: everything recommended for adults teaching children aged 4–16 is free and runs in a browser. If a product asks you to pay before your child can finish an activity, there is almost always a free equivalent.
