What caught my attention here is the ability to pan — to move around on the large newspaper page with the mouse by dragging the hand pointer. Use of mouse panning was introduced with Google Maps, and likely played a large part in its becoming so popular. Like a map, a newspaper page poses the same kind of challenge — How to design user navigation for information covering a large surface. As with Google Maps, here also it looks like Google Newspapers has set the standard for navigation of a large-paged information source, especially one with pictures.
Panning (and zooming, which is often discussed together with it) provide an interesting and challenging concept to search, because the words are in prominent use in other contexts, especially photography and video. Surprisingly, there’s no article in Wikipedia for the concept of panning as used for computer information navigation.
An elegant demonstration of panning is at the Hubble pan and zoom gallery.
