Abstract

An in-vehicle display apparatus includes a communication device and an in-vehicle device. The communication device acquires information posted by the user and geographical location data indicating the destination of the posted information and classifies the acquired posted information into categories. The communication device generates map data in which the posted information is displayed in a display format corresponding to the classified category at a position on the map specified by the geographical location data that is acquired together with the posted information and transmits the map data to the in-vehicle device. The in-vehicle device displays the received map data on, for example, a liquid crystal monitor.

Claims

1. An in-vehicle display apparatus that is provided in a vehicle and displays information posted by a user, comprising:

a category classifying unit that classifies the posted information into categories; and

a display unit that displays map data in which the posted information is displayed in a display format corresponding to the category classified by the category classifying unit at a position which is specified on the basis of geographical location data indicating the destination of the posted information.

2. The in-vehicle display apparatus according to claim 1,

wherein the display unit displays the map data in the display format including an operation unit that displays the details of the posted information,

wherein, when receiving an operation input to the operation unit, the display unit displays the details of the posted information.

3. The in-vehicle display apparatus according to claim 1,

wherein the posted information is displayed so as to be selected by the operation of the display unit, and

wherein, when one of a plurality of posted information items displayed on the map data is selected, the display unit displays these items that is edited in a list format.

4. The in-vehicle display apparatus according to claim 3,

wherein the display unit displays the plurality of posted information items that is edited in a list format in which the posted information items are arranged in time series on the basis of the post time, a list format in which the posted information items are arranged in ascending order of a distance from a position on the map data where the operation is received, or a list format in which the posted information items are arranged in the categories classified by the category classifying unit.

5. The in-vehicle display apparatus according to claim 1,

wherein the display unit displays fixed phrase related to the posted information so as to be selectable and displays a selected fixed phrase at the current position of the vehicle on the map data.

6. The in-vehicle display apparatus according to claim 5,

wherein the fixed phrases are prepared for each of the categories classified by the category classifying unit.

7. The in-vehicle display apparatus according to claim 6,

wherein the fixed phrases include a fixed phrase that varies depending on at least one of the season, time, weather, and taste of the user and a fixed phrase that does not vary depending on the season, time, weather, and taste of the user in each of the categories classified by the category classifying unit.

8. The in-vehicle display apparatus according to claim 1,

wherein the display unit displays the map data in which directional information indicating the direction of a position where the posted information related to predetermined taste information is displayed or a position where the number of posted information items is larger than that of previously displayed posted information items by a predetermined value is displayed.

9. A display method that displays information posted by a user on an in-vehicle display apparatus, comprising:

acquiring the posted information and geographical location data indicating the destination of the posted information;

classifying the posted information acquired by the acquiring into categories; and

displaying map data in which the posted information is displayed in a display format corresponding to the classified category at a position specified by the geographical location data which is acquired together with the posted information by the acquiring.

10. An information display system comprising:

a communication apparatus that acquires posted information; and

a display apparatus that displays the posted information,

wherein the communication apparatus includes;

an information acquiring unit that acquires the posted information and geographical location data indicating the destination of the posted information; and

a category classifying unit that classifies the posted information acquired by the information acquiring unit into categories, and
