Even though some of these cards do overlap to varying degrees, at least part of them is still visible to the user and can be queried using the cursor. Simple colour coding is also used to further identify hierarchical structure, so immediate child pages are shown in green and further grandchild pages are blue. Users can interact with the MAPA map in several ways. Firstly, passing the cursor over a card will cause it to be highlighted and for the title to be displayed as a flag. Titles are displayed in such a manner that they are all visible with minimal overlapping.
Users can also navigate within the map itself by re-focusing the layout around a different page.
This is achieved by clicking on the cards with a dark bar on them and the pages rearrange themselves in a smooth animated transition. With the animation most people can get it. And it is fun to watch the pages march across the screen and rise up out of the carpet. Finally, MAPA can be used to move the user's browser to a different page in the site simply by double clicking on a card of interest.
