I'm trying to find keywords to search for implementations of this style of navigation for a tree of content: screenshot

Clicking on a different box recenters the tree on it, allowing exploration of a complex interconnected tree in a fairly intuitive way.

  • Can you provide a link to this? It is hard to get a feel for the interaction or behaviour just by looking at the static image.

  • Unfortunately, it's in a game rather than a web page, so I can't easily link. It's available on gog.com/game/sid_meiers_alpha_centauri if you like old turn based strategy games with philosophically interesting characters and an expansive plot.

It seems to me that this is just a tweak of the Miller Columns UX Pattern, except instead of displaying all the items on your current level and all the items of the previous level of the tree, you display just your current node itself, and its parent(s). And all the child nodes of course.

And you just display the three levels (with Miller columns you usually get more).

A close relative is the Drilldown Navigation pattern, most commonly found on your smartphone. When you explore a tree on your phone you'll usually see the next level, with sometimes the title of the current screen representing the current node, and with no representation of the previous level of the tree. Here you have all three on the same screen, but otherwise it's pretty much the same - you basically have a viewport sliding along a navigation tree that's been spread horizontally.

A possible suggestion is a 'dynamic' radial tree/map navigation or display. The reason is that something that automatically centres where you click means that there is no specific 'root' of the tree, and 'radial' because it is branching out from a central point rather than being aligned to one side of the node.

To be honest I haven't seen many actual implementations of this style of design (certainly none off the top of my head), but you'll probably find it where there are customized designs used to explore novel datasets or aggregates of datasets.

We built some prototype navigation systems like this that leverage ontologies. I think smartlogic has a product that also does this navigation style for one of their products as well that leveraged flash and was recently upgraded to an html 5 coordinate based system leveraging x and y coordinates. I don't have a name for it though, although internally we call it a Web navigation system since each node can have one or many threads leading to additional nodes. Not sure if that helps...

I believe it's some free form of a dialog tree, a technique frequently used in RPG's. I'm not quite sure if you will find what you're searching for with that keyword though.
