I recently bought a book that uses an audio pen to read the pages. You point the pen at the text in the book and can hear it read aloud. I’m wondering what kind of technology is involved here and if more of these books are available? Is there special software needed to convert text into encoded dots so the audio pen reads them?

Your question depends a bit on what type of reading pen system you are using, as different companies use different technology. Products such as LeapFrog Tag(opens in a new window) and VTech’s Bugsby Reading System(opens in a new window) use specially-designed books with their reading pens. In order to access more titles, you will need to purchase their books, most of which are targeted towards younger or early readers. The benefit of books like these is that the text is typically read by a human voice, rather than a computerized voice. Children can also click on different icons within the text to get more information or sound effects while reading. The disadvantage to such products is that they can only be used with a limited number of titles and so may not be a good solution for a student with disabilities who needs to access a wider array of books. You may also look at the different types of reading pen/scanners available(opens in a new window) — many of these tools you use like a highlighter, running over printed text and getting instant speech feedback. While most of these pens are not appropriate for reading an entire book, they can serve as a valuable support for difficult words, definitions, and pronunciation.
