My first search engine, is a program that acts as a pictorial version of 20 Questions. It is installed on a touchscreen.
There are multiple different abstraction, based on skill level of baby or child.
Baby: Single sheet of multiple common objects/concept, showing and speaking name when clicked. All are icons representing concepts. Each icon speaks when clicked.
Toddler: Upper half of screens shows search categories, and bottom half shows results found. Clicking top categories will narrow the results on the bottom half, and go down a category level for the upper half.
Child: Similar to Toddler mode, but is via words. Keyboard quick search could be implemented.
