Nokia posts plans for Symbian^4 touch screen interface

Symbian, most widely used by Nokia, has fallen behind smartphone OSes like iPhone OS, Android and the BlackBerry's OS, which are driven by touch-based displays.

In Nokia's S^4 Interface Concept Proposal, Nokia proposes that Symbian phones display four main screens for music, photos, applications and contacts, and it posted some sample examples.

Other proposals include a similar look and feel for all Symbian applications, the ability to customise the home screen by placing shortcuts to access applications, and context-based menus.
