This is probably not a surprise to many people, but the 2011 Horizon Report has listed eBooks as a technology that has one year or less to adoption.
From the Horizon Report: “Now that they are firmly established in the consumer sector, electronic books are beginning to demonstrate capabilities that challenge the very definition of reading. Audiovisual, interactive, and social elements enhance the informational content of books and magazines. Social tools extend the reader’s experience into the larger world, connecting readers with one another and enabling deeper, collaborative explorations of the text. The content of electronic books and the social activities they enable, rather than the device used to access them, are the keys to their popularity; nearly everyone carries some device that can function as an electronic reader, and more people are engaging with electronic books than ever before.”
Mobile is another one year or less to adoption technology.
Augmented reality and game-based learning are two to three years out, and gesture based computing and learning analytics are four to five years out.
