Fujitsu in collaboration with video game and simulator developer Ongakukan has developed the world's first train simulation system using full high-definition video. Through its technical collaboration with video game and simulator developer Ongakukan, Fujitsu was able to develop variable-speed playback technology for high-definition video shot on actual train lines, the first use of this technology in a train simulator. The result is an unprecedented level of realism in train operation simulation, with accurate responses to the trainee-operator's input and high image quality even with variable-speed playback. This gives trainees a better approximation of the operational environment to help improve their skill levels.
