Apps have been developed for a wide range of books, ranging from early baby books to picture books for older readers to nonfiction books for young and old. With each, the most important aspect to consider is the audience. In all the cases where I am considering an app, I want to think about the reader or learner it was designed for.
Navigation
Other apps have clear directions explaining how to navigate through their pages. For example, Journey Into the Deep has a fascinating selection of symbols that guide users to digging deeper into the content of a chapter, taking you back to the table of contents, or revealing content within pictures. At the bottom of this app is a sliding scale that indicates where in the book you are at any moment. This sophisticated navigation structure allows users to explore different parts of this complex book in a way that makes sense to them, and always makes it easy to return to the table of contents.
Many picture book apps will remember where readers left off reading, so when you open them they will ask you, "Do you want to resume where you left off, or start from the beginning?" Many picture book apps have a table of contents with a thumbnail picture of each page, so young pre-readers can choose the page they want to go to. This is a very important navigation feature for young readers to give them a sense of independent control.
One of my favorite things with a read-aloud picture book is a simple way for users to listen to a page being read aloud again. What if a young listener wasn't paying attention for a moment. How easy is it to press the "replay" button, as it were? What if you want to listen to a song again? Can you do this easily, or do you have to go back a page and then forward again? The apps for Angelina Ballerina and Miss Spider's Tea Party, from Callaway Digital Arts, do a particularly good job of letting young readers navigate in an intuitive but clear way, letting them listen to a page repeatedly if they wish to. This is important, especially since these apps have quite a bit of text on one page.
An interesting navigation feature that picture book apps are working through is how to present longer text on one page. Some picture book apps put all the text from a print book on one app page. Wild About Books keeps the original page layout from the books. This works well for the rhythm and rhyming of the book, but I find the font to be quite small for children to read along with the story or read by themselves. Some picture books, like The Competition from Piccolo Books, use turns within a page (with an arrow next to the text), as well as larger page turns (with page swipes or arrows at the top of a page). I wonder how well children use this more complex navigation.
I would love your thoughts on the issue of navigation for children's book apps.
