Transactions on Edutainment X 

This journal subline serves as a forum for stimulating and disseminating innovative research ideas, theories, emerging technologies, empirical investigations, state-of-the-art methods, and tools in all different genres of edutainment, such as game-based learning and serious games, interactive storytelling, virtual learning environments, VR-based education, and related fields. It covers aspects from educational and game theories, human-computer interaction, computer graphics, artificial intelligence, and systems design. This special issue consists of two parts: the first one features original research papers on interactive digital storytelling in the applied context of edutainment; the second part contains a selection of revised and expanded best papers from the 4th e Learning Baltics (e LBa 2011) conference. The papers on digital storytelling have been split into sections on theory, technology, and case studies; the e LBA 2011 conference papers deal with technology and applications, case studies and mobile applications, and game-based learning and social media.
