Yet another patent application from Mountain View today. While the first one was related to
adding sound triggers to e-books, which may not appeal to everyone, this application serves a more practical purpose: the synchronization of reading and listening locations between e-books and audiobooks.
While not granted (yet), the USPTO filing outlines an "e-book system" that would synchronize reading locations not only between e-books stored on different devices (perhaps even in different e-book formats), but also locations between audio/audio-video content and text content. For that purpose, the audio content is first transcoded into text and then compared to the original text version.
Quote:
Oftentimes, e-books are available for consumption in a variety of different modes. For example, an e-book may be available in a traditional text-based version for consumption by reading, and also available in an audio book version for consumption by listening. The audio book version may be narrated by a human actor or other voiceover professional that reads the text with added nuance such as tone or inflection that enhances the enjoyment of the listener.
A user may desire to occasionally switch among the various consumption modes for an e-book. The user may read the text version of the e-book when relaxing at home, but desire to listen to the audio version of the e-book at other times, such as when the user is driving. However, switching among the consumption modes is difficult because the different versions of the e-book are independent. There is no easy way for the user to maintain the same reading/listening position between the text and audio versions of an e-book. Thus, the user must manually locate the correct position when switching consumption modes. This extra effort is time-consuming and detracts from the user's overall enjoyment of the e-book. [...]
The above-described and other issues are addressed by a computer-implemented method, computer-readable medium, and computer system for switching between synchronized consumption modes of an e-book.
