  • Patent number: 9154578
    Abstract: In a communication terminal device, in a case where the arrangement of the windows is changed in a list screen, an overhead screen is initially displayed, in which the list screen is overviewed, and the arrangement of the windows is subsequently changed in the overhead screen, and a magnified screen (original screen) of the overhead screen, in which the arrangement of the windows has been changed, is displayed last, as described in the foregoing. By displaying a magnified image, it is possible to make windows better visible in a small display area of a mobile phone. Also, in a case where a window exists that cannot be displayed in a magnified screen, by displaying an overhead screen, it becomes possible for a user to recognize a fact that a window that cannot be displayed exists in a magnified screen, and also recognize a position of the window.

  • Patent number: 9112994
    Abstract: The environment around mobile phone handset 10 is judged according to the number of other mobile phone handsets present near mobile phone handset 10 and the registration status of the nearby telephones. Then, the display sequence of function names on a function selection screen is changed according to the environment. As a result, functions deemed likely to be selected by the user based on the environment surrounding mobile phone handset 10 may be displayed at positions where they may be selected with fewer operations. In this way, the number of operations required of the user for selecting any of multiple functions may be reduced.
