Inspired by the discussions of the design team meetings, I have been playing around with a few ideas for a simple navigation model for the mobile that can extend the feature set of tools and options available to users. It struck me that the article lead, some images and infobox data can give a very good idea of a topic that is alien to the reader and such a compact view on the mobile screen has a lot of value.
It got me thinking of the possibility of decomposing any wiki page into multiple 'views' or layer that can alter the way one views the same page by selectively rearranging and hiding the content. Possible page layers could be:
A) Overview: Condensed view of the article optimized for the small touch screen. It can also contain an index of topics covered that can act as navigation aid to jump to a section in the Article layer
B) Article: The whole article, just like what you see in the current mobile site
C) Gallery: Thumbnails of pictures, videos from the article. Could also fetch related content from other wikimedia projects
D) Category: Allows you to jump to related topics if you are interested in the subject.
E) Discussion: The talk page to discuss
The search and other page functions including language selections go into a menubar that floats above the article. It would work like the menubar in Google Now which Pau had demoed. When you scroll down its hidden, as you scroll up, the menu pops up again, which means that all the functions including search can be accessed from any part of the page. This also saves screen space when you are reading and scrolling down, giving you a full page view of the article with no distractions.
You can see a visual overview of this here:
Just an idea, more discussion with the design team pending.
