Create e-textbooks with Dbook’s New Version

Two years ago, I have mentioned a promising software called Dbook, a mathematics software developed by the Center for Research for International Cooperation in Education Develoment (CRICED) of the University of Tsukuba in Japan. Dbook lets you create interactive electronic textbooks from scanned images or those which were created in word processors and desktop publishing software. Recently, Dbook’s new version was finished, although I am not sure if the software had been released online.  However, to know the capabilities of Dbook, here are some tutorials on Youtube by Prof. Masami Isoda of CRICED.

For more information about the Dbook (older version), you may want to visit the official website.
