Nowadays Sony Ericsson patents a lot of interesting solutions: the one presented today is a phone coming with more, that is three types of input devices. Mobile phones now do not function only as phones, but they can be used for taking photos, navigating, playing music or playing games and all of these applications would need a different type of input solution, that is navigation from the phone's standard controls is not always comfortable. W350, model of the Japanese-Swedish manufacturer, is a Walkman that has its numerical keypad covered by a flip that has the logically organized buttons of the music player, so when the flip is closed the music player can be controlled comfortably, and when opened the handset can be used a standard phone, thanks to the conventional keypad. This patent takes this idea even further: the flip can also be closed after turned over, that is three different types of keyboards can be put in a handset.
