In your own words,and from your imagination ,try to invision a futuristic input method support your answer with photo/sketches if /when possible

I have a idea that  in  the case of the screen is not lit, as if after a careful handling of the "crystal" as crystal clear. When light up the screen after this type of phone will be quite transformed, to become a "Mr. Weather", immediately showing real-time weather conditions outdoors. It is reported that, when the weather is fine, this seems the entire screen on the phone will be very "clear and bright"; if it is wet rainy day, the phone will see the raindrops on the screen pattern; if it is snowing weather or large foggy weather, then it will appear on the screen the effect of white, just like mobile phones capped with a layer of mist or frost. Even more interesting is that you only need this phone to gently breathed on the screen, the screen on the input state can immediately switch to handwriting.
