Abstract: A radio apparatus transmits a radio signal including identification information for identifying the radio apparatus. A reception terminal receives the radio signal transmitted form the radio apparatus. A positional information management server obtains radio information in which the identification information included in the radio signal and radio field intensity of the radio signal are associated with each other and determines a position of the reception terminal using the obtained radio information. The radio apparatus includes an antenna that transmits the radio signal having directivity toward a floor.

Abstract: An information processing terminal (100) displays contents that are sorted by date information and category information. The information processing terminal (100) includes a display (114), a touch sensor (112) for detecting an input from a user on the display (114), and a control unit (140) for displaying, on the display (114), the date information including a plurality of dates, the category information including a plurality of categories, and contents belonging to a date and a category that are selected by the user from among the plurality of dates of the date information and the plurality of categories of the category information. When a date different from a date of currently displayed contents is selected, the control unit (140) displays, on the display (114), contents of the selected date that belong to the same category as a category of the currently displayed contents or a category similar to the category of the currently displayed contents.

Abstract: An information processing terminal (100) is capable of displaying contents that are supplied as print on paper and provided electronically as well. The information processing terminal (100) includes a display (114), a touch sensor (112) for detecting an input from a user on the display (114), and a control unit (140) for displaying the contents on the display (114). The control unit (140) switches between a first display mode for displaying list information of the contents on the display (114) and a second display mode for displaying the contents on the display (114) in the same layout as a layout of the print on paper in accordance with an instruction from the user.
