Unfortunately, many readers found the videos and additional media distracting, particularly for works of fiction. (I could have told you that countless nonconsecutive video clips do not help a reader immerse him/herself in a fictional world.) Vook has since moved toward more nonfiction titles, however, and received a better response.
How a Vook differs from the Internet, I have no idea.
However! If you thought the Vook was the pinnacle of book/media mash-ups, you thought wrong. Enter Booktrack, a company that makes soundtracks for books.
Yes, soundtracks for books. Now while you're reading about a forest, you can hear THE SOUNDS OF A FOREST. Like, I don't know, birds and whatnot. When Bro McLadiesMan begins playing a mega sweet power ballad for his lady fair, you can listen along. When you get to a super intense part, you get to listen to super intense movie trailer-style music. &c, &c. (There are previews on the Booktrack website if you're interested.)
The Booktrack speed can be adjusted to your reading speed, as well, so the synchronization between sound effects and text should be reasonably good.
Be that as it may, I think I'll find Booktrack books similar to Vooks: over-hyped and distracting. I'm all for innovation in the field and I think it's necessary to the future success of print media, but I'm not sure rocking the audio equivalent of a movie trailer in the background is the best way to achieve this.
However! I'm curious, as always, to hear what you think. So, mes auteurs: yea or nay on the Booktrack experience?
