How is this different from an ordinary coloring book?
An ordinary coloring page states something. A dog. A truck. A farm.
Our pages ask the child to decide something, and the crayon records the decision. Two lemonade stands, one busy corner, one empty back yard, and the question of which one sells more. Six pictures, four dogs, one cat in a costume, and the question of which ones we should show a computer that is trying to learn what a dog is.
The coloring is identical. What changes is that the child left the page having made a call.
