The Second AR tag in Akihabara

October 25, 2009

On 17th October, Akihabara, we played experimented in AR tag again. Only 2 people were in the first, most of us were new players in this second time.

Makoto (UEI) developed an AR camera app for this tag game and we used it experimentally.  

As you can see, players and It are shown as blue circle and the building of Yodobashi-camera is shown as red one. The lengths to them are also indicated.  The app was better than expected and we could find the place and direction to It easily.

A camera pass-through AR makes invisible information visible like this app indicates the places of the players, so it has a similar effect to the application of optical camouflage innovated by Mr Inami.

Also we played the game in much narrower area, Kanda-izumichou.  The area is narrow and complicated. So we utilized such uniqueness of the map and made a strategy. We pretended to gather in the same place by pushing repeatedly “search” button.  When it came near, we run away at the same time to different directions.


However, team of It also made their strategy. They shut out our ways and attached us from bot sides!

The man in leather jacket and the girl were It…! 

Though our strategy was failed unfortunately, but it was really thrilling time as that was the first intellectual play in these AR tag games! 

The server for AR tag app (the same one as before) seemed to be enhanced and fixed so we could use it more smoothly.

Interesting time passed really quickly and our iPhones’ batteries were also consumed so we stopped playing after 4 games has been done. This time was really enjoyable as the first.

Thanks so much everyone for coming! 

Oh! I should not forget to tell a great contribution by Mr Itoh. His live camera recorded how we play the game.  Check it out from here!
