When developing Android applications the interface layout is usually defined in XML files. Commonly the file main.xml is the definition for the first interface that the application presents to the user.
Android also allows for different layouts to be defined in XML files in different folders. The names of the folders define when the layout should be used. So, for instance, the layout-land folder holds the layouts for the application when running on a device in landscape mode. This method allows design and function to be neatly separated.
It occurred to me on the train this evening, whilst working on an app, that it might be handy to have folders for left and right handedness. This would allow for asymmetric designs, especially in portrait mode, where the device – typically a phone – is being held in one hand. So if an application has multiple buttons on the display for instance, then the more important buttons could be sized/positioned to make them easier to reach.
I don’t know if this already exists, but I wanted to get it out there so that there is prior art, hopefully preventing the likes of Apple, Microsoft and RIM from claiming it as a novel invention and patenting it.
