The paper has the following organization. Thus, these games also facilitate development of the team spirit. Each student can carry out the activities s/he feels most congenial and, by working together, the whole group can solve the game challenges and overcome difficulties thanks to their common efforts. Educational games are very valuable since they foster relational skills, encouraging young people to work in groups and collaborate to attain given objectives. Groups of students may actively collaborate to solve the challenges proposed in the two games, manipulating by hand gestures the objects displayed. ![]() To this aim, we have developed History-Puzzle and Time-Voyager, two applications for large multitouch screens, which implement two different educational games, as described in this paper. park and before the debriefing phase, children might get further knowledge about the historical site. The TUIO protocol has been adopted to allow communication between the touch-capture system and the software application. The games presented in this paper have been developed in Java, thanks to the open source MT4J (Multitouch for Java) development platform. For example, MultiTouch Ltd provides an SDK, called “Cornerstone”, that requires C++ and OpenGL programming. Multitouch hardware manufacturers provide Software Development Kits (SDKs), but customers need to have specific skills to be able to use them properly to program their own software applications. Developing software applications for multitouch screens is still not easy. However, the screen needs to be completely disassembled for transport and, each time this happens, the projection system and touch sensors will then have to be re-calibrated. In fact, the screen is made of a normal safety window like the ones used for shop windows, so in case of damage, by vandalism for instance, it is only necessary to replace the glass and not costly LCD panels. This technology is less costly than a format consisting of several combined LCD panels and, above all, less delicate. Various modules and accessories can be selected to meet customers' application in various industries.Schema of a multitouch box using diffused illumination. ± 8KV contact discharge, ± 10kV air dischargeĪccessories of 10.1'' Windows Tablet EM-I17J Rugged PC and distance from sample top side to water surface at least 0.15m.
