Navigating a 13.3 gigapixel image on a 22 megapixel display wall

Gigapixel images are great, but navigating them on a regular sized display through a slow web browser isn't such a great experience. This video shows how we navigate a 13.3 gigapixel image of Tromsø, Norway on a 22 megapixel display wall, using a custom, camera-based multi-touch interface and a custom system for high-performance navigation and visualization of high-resolution datasets.

The image was taken by photographer Eirik Helland Urke, who also operates the www.gigapix.no website. He kindly gave us access to his data so that we could present and view it on our display wall. The system for visualizing the high-resolution image is called WallScope. The system was created by Tor-Magne Stien Hagen, and incorporated with Daniel Stødle's Interaction Spaces system for device- and touch-free interaction with display walls. All of this under the careful guidance and advise of Professor Otto J. Anshus.

Sorry, as an artist I have to say having consistent color and light is far more important than resolution. In other words, I'd much rather have a 1080 screen with good color and light, then 20 1080 screens stitched together, each with different color and brightness profiles. If they could make it seamless like from a single projector, it would be much more worthwhile.

There are a number of approaches one can take to match the projectors in brightness, color and blending overlaps. Our wall is getting old, built about six years ago. At the time, we found that doing these corrections stole too much performance from the applications we wanted to run. Had we had more recent hardware, I would probably take a closer look at these approaches. It was never built as a commercial system, though, so these faults don't impact the research results we are getting from it :)

that'd be 1 crazy --wheres waldo?--lol

How much megapixels is...

*Puts on sunglasses*

GOOGLE EARTH?

YEEEEEEEEEAAAAAAAAHHHHHHH!!!!!­!!!

Or should I say...terrapixels o_o

[GamerMGO]

pshhh its TERApixels that are all the rage now...

@tooosweeet And when the wheel was invented I bet there was a guy just like you complaining;"Ya, but where’s the car". It is called a building block.

minority report inspired

[dreemLight]

i don't see what this has to do with a slow web browser. 

[FloOFy2]

Lol, the makings of minority report are coming alive. Imagine having this in your house, just have a really big curved screen around you and you're controlling everything with movement.

this product wont for me cause I CANT SNAP MY FINGERS :(

its just an ipad hes just really tiny
