Teachers wanted students to create a fictional character for a book that combined words together to create a whole word. This fictional character would be created for a child's book, so of course it had to be child friendly. Main problem was that they didn't have a character that they could think of so that is where the idea comes in place.
My solution to this was to think of a common word that we use on a daily basis so "Keyboard" was the idea around this design. The Keyboard concept came to me as the key would come from a computer keyboard like the key caps we see when we are typing, it would be riding a board like a skateboard. When we put it together we see a keycap riding on a board, "KEYBOARD".
