This is application using Geolocation and Augmented Reality. We can puts the data of the armed forces which participated in the Battle of Sekigahara on a map of current Sekigahara and watch it.
Furthermore, we can check the name of samurai warrior and superstar warload when we enlarge a map. And when we click the name …
In addition, we can put AR shadow of samurais on scenery of current Sekigahara. Of course they are based on geolocation.
There is a method to realize a battle even if you cannot go to Sekigahara. You can put the lines of the Battle of Sekigahara on the hometown. Then you may realize the area of the battlefield more.
By the way, the Battles of Sekigahara happened on September 15 of the old calendar(It is October with the current calendar). The tourist industry of Sekigahara becomes busy from now on. I think that Sekigahara town office should use this application for sightseeing promotion.
