Amazon VP Jay Marine said that X-Ray doesn't require the book publisher to do anything differently--the burden of work is on Amazon. Behind the scenes, it is using things like Shelfari, Amazon's community-powered book lover encyclopedia, and Wikipedia to build its metadata, and that gets sent as a sidecar of the book, which Marine says "becomes a dictionary of the future."
Amazon is adding features like X-Ray to try to reduce the friction that still exists for those still making a transition away from paper books. The company also added a little timer that shows how long you have left in a chapter, based on its sense of how fast you read. I'm almost convinced, but I'm not sure what I'll do with my bookshelves now--firewood, anyone?


Amazon is hardly satisfied with that. It also announced WhisperSync for Voice, which lets you listen to audio books (Amazon has added 100,000 new audio books to the Kindle Fire HD), and seamlessly switch to reading mode, and back without losing your place. An Immersion Reading feature highlights words as the audio track plays; Amazon pointed to studies indicating that this method can help enhance reading and retention capability. Amazon is adding the Immersion feature to titles as fast as it can. For now, Amazon says nearly 15,000 Kindle books are available in Immersion mode.
So Amazon's got the digital book market pretty well cornered. If it can continue to pressure Apple on music, movies and TV shows (for purchase, streamed, and otherwise), by being just as inventive, we might have an entertaining, competitive battle. On Thursday, Amazon did announce X-Ray for movies, which is somewhat similar to the service on books. The movie version uses IMDb meta data, but it applies it on a scene-by-scene basis: just touch an actress on your screen (keep it clean, please), and it brings up information about her, including a list of every movie she's been in. Once again, the content creators don't have to do a thing here.
Here's something parents should love: Kindle Free Time. This is basically parental control. You can go into the Kindle Fire and restrict the amount of time that specific device users (like each child) can consume particular types of content. You might choose unrestricted reading, for example, but only an hour of games or movies.

And while Kindle Free Time is intended as a parental tool to govern a child's use of the addictive device of the moment…well, I'm sure you might easily see where this could go in an enterprise setting. But perhaps we're teetering into Hollywood screenwriter territory now.
