Mobile Mixed Reality games are games that are played in a physical environment augmented with virtual game artifacts. While former Mixed Reality applications were mainly stationary, advances in mobile computing and positioning technology have made this new type of games possible. Players wear mobile computers equipped with positioning technology, head-mounted displays, laptops, personal digital assistants, or mobile phones in order to play this kind of games.

Early prototypes such as ARQuake, Human Pacman, or NetAttack showed the technical feasibility but also the potentials of mobile Mixed Reality games. Players find it fascinating to play their own avatar, to physically move in the game world and to directly interact and compete with their co-players. The close integration of Mixed Reality games in the physical environment offers a new player experience that cannot be achieved with traditional computer or console games.

While the technology has matured since the first games in this field leading to Mixed Reality systems running on off-the-shelf computers and there are already some related commercial systems available such as Sony's Eye of Judgment, many issues related to the design, development and evaluation of mobile Mixed Reality games are still open and need to be further researched.

We would like to invite papers to be submitted to this special session of DIMEA 2008 that focus on one or several issues of Mobile Mixed Reality Games including but not limited to: . Design and evaluation of Augmented Reality and MR games . Design guidelines for Augmented Reality or MR games . Ethical issues of mobile Mixed Reality games . Positioning technology for MR games including marker-based and marker-less tracking . MR hardware and software systems for games . Tools for rapid prototyping of MR games

In the special session we will bring together researcher and practioneers who work in this new and emerging field of MR games. The session will draw the attention to the potentials of this new form of media in entertainment and will push the state-of-the-art in this field.

* SUBMISSIONS *

Please note that the submission and review of papers for the Special Session will be conducted through the same on-line system (www.dimea2008.org) used for regular papers. Papers submitted to the Special Session should follow the same style as regular DIMEA papers. Authors are invited to submit full technical papers of not more than 8 pages, including tables, figures and references. Papers should present original research related to the above mentioned scientific areas, not published elsewhere. Full paper submissions should adhere to the ACM SIG Proceedings style guidelines. The respective templates may be found at:
