| 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. You can read more about the system at www.cs.uit.no |
