Sekai Camera is an iPhone application/service that allows you to place air tags and photos in any location around Japan - and soon the world when its launched worldwide.
Its currently available for a free download from the app store.
Here I have Sekai Camera booted up on my iPhone. It uses the GPS and compas in the iPhone 3GS to determine where the phone is and in which location the phone is pointing in.
As you can see from this photo, there are things floating about the screen and a radar type display at the top.
As I move the phone around, the tags and photos will scroll with the view until they disappear off the side of the screen. That's because those tags and photos are tagged to a single location.
The video below in Akihabara gives you a good idea of how it works. In the video you will see tweets, photos and air tags floating about. In the video, you will see a load of green air tags with the name "姉ヶ崎 寧々" (Anegasaki Nene) - a character from Love Plus. A load of Nene fans went around spilling her name all over the place.
Here I am having lunch tagging my food. The tag will remain in this spot forever and can be seen by anybody else with an iPhone+Sekai Camera in the area.
If I click on a tweet or an air tag, I can see who left it there - their photo and profile. As you saw from the Sekai Camera vid in Akihabara above, air tag pollution is starting to happen with the area just full of tags.
We planned to do a hijack of a town leaving Mirai-chan's image everywhere but not got round to it yet ^^;
I can see use cases where shops can leave food coupons floating outside their shop.
By looking at the world through Sekai Camera, not only can you see the normal stuff that you view with your upper set of eyes, you can also see a whole lot more information including landmarks.
When somebody clicks on a photo, tweet or air tag I left lying around, they would see my profile like this.
Another interesting thing about Sekai Camera is that you can "pocket" stuff. If I see a photo or air tag left by somebody, I can pocket it and view it later. Great for treasure hunting games.
Speaking of hunting games, Steve Nagata and I are planing a hunting game with Sekai Camera in Akiharbara soon. Each contestant will have Sekai camera on their iPhone and be paired with a camera wo/man.
The aim of the game is for the Hunters to catch the Runner. Each Hunter and Runner must leave an air tag at their current location every 3 minutes which will allow all players to know each others general location. Hunters will hone in tags left by the Runner in order to catch him/her. The Runner will see tags left by the Hunters so that he/she can run.
A map of Akihabara will be provided with a Barrier around the play area. Players must not go past the Barrier or its game over for them.
The game will be filmed, edited and released to the Tubes. More details as we flesh em out.
With Sekai Camera, its the world as we know it with a digital layer on top - get it from the App store. I think its only available from the Japanese app store but if you manage to download it, does it work where you are?
