Information displaying device and method for displaying information

A vehicle-mounted information displaying device comprising:

• an input unit that receives operations from a user;
• a movement state evaluating unit that evaluates a state of driving of a vehicle;
• a display information generating unit that generates screen information including a plurality of user interface elements to be displayed on a display of the vehicle-mounted information displaying device, based on a layout selected from predetermined layouts according to the state of driving of the vehicle;
• and
• an operation detecting unit that detects the operations on each of the user interface elements, and counts a frequency of the operations on each of the user interface elements in a period that the state of driving is traveling and not when the vehicle is stopped, wherein
• the display information generating unit generates the screen information based on a basic layout displaying a first predetermined number of the user interface elements when the vehicle is stopped,
• the display information generating unit generates the screen information based on a travel layout when the vehicle is traveling displaying preferentially a second predetermined number of user interface elements with higher frequencies of the operations and less than the first predetermined number on the display;
• the display information generating unit generates displays the user interface elements in the travel layout in sizes that are larger than in the screen information based on the basic layout,
• the display information generating unit generates the screen information which divides the display into a plurality of divided areas, each of the divided areas are assigned to display a different predetermined function,
• the input unit receives an operation to change a plurality of sizes of the divided areas,
• the display information generating unit displays a user interface element, which was not displayed prior to the change of the sizes of the divided areas, in the divided area enlarged by the change of its size, and
• the operation detecting unit counts the frequency of the operations for each of the user interface elements.
