Abstract: A vehicle state detection unit detects whether a vehicle including an information apparatus is in motion or stopped. A display control unit displays operation items related to various functions provided by the information apparatus on a display. A function execution unit executes a function corresponding to a selected operation item. An identification unit identifies the frequency of use of each operation item by classifying the items according to whether the vehicle is in motion or stopped. The display control unit further displays on a prescribed menu screen in which some of the operation items are aggregated. On the prescribed menu screen, when the vehicle is in motion, the operation item identified as having a high frequency of use when the vehicle is in motion is displayed, and when the vehicle is stopped, the operation item identified as having a high frequency of use when the vehicle is stopped is displayed.

Abstract: To improve user convenience when selecting items, an information processing device includes: a display control unit for controlling display of a menu screen containing at least one of a plurality of items for respectively instructing execution of a plurality of functions; an evaluation unit for evaluating use frequency of each of the plurality of functions within a first period; an alteration proposal unit that provides a proposal to an user regarding changing the appearance of some of the items on the menu screen based on the use frequency; and an alteration execution unit for executing the change in the case an instruction to accept the proposal is received from the user.

Abstract: An information displaying device comprises: an input unit that receives operations from a user; a movement state evaluating unit that evaluates a state of movement of the mobile entity; a display information generating unit that generates screen information including UI elements (user interface elements) to be displayed on a display, based on a layout selected from layouts according to the evaluated state of movement of the mobile entity; and an operation detecting unit that detects the operations on each of the UI elements, and counts frequency of the operations on each of the UI elements while the movement state evaluating unit evaluates that the mobile entity is traveling; wherein, in the screen information based on the layout selected when the mobile entity is traveling, the UI elements with higher frequencies of the operations, which are detected by the operation detecting unit, are preferentially displayed on the screen of the display.
