Students at the University of Tromso in Norway have created an interactive display wall using 28 separate projectors, which creates a 7168×3072, or 22 megapixel, display. Interactive with the display simply involves placing your hands in front of it. Touching the display itself is not necessary, and multitouch is supported. What better way to demonstrate the capabilities of such a system than zooming through a gigapixel photograph?
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.
Here’s an amazing video demonstrating the wall in action:
Ah… A glimpse of the future. We may soon find ourselves post-processing our photographs on our walls at home.
