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, comprising:

an acquiring unit that acquires a plurality of posted information items which are posted by a plurality of users in real time and to which geographical location data indicating a destination of each of the plurality of posted information items is added;

a category classifying unit that specifies a posted information item to be displayed from the plurality of posted information items based on a hash tag included in each of the plurality of posted information items, and classifies the specified posted information item into categories, which are not categories by the geographical location data indicating the destination of the posted information item, based on the hash tag; and

a display unit that displays map data in which the posted information item is displayed, using a display method that is changed based on an elapsed time from the posting of the information to the acquisition of the posted information by the acquiring unit, in a speech-bubble-type icon of a color which is specified according to the category classified by the category classifying unit at a position which is specified on the basis of the geographical location data, when the elapsed time from the posting of the posted information item to the acquisition of the posted information item that is acquired by the acquiring unit is less than a predetermined time.

2. The in-vehicle display apparatus according to claim 1, wherein the display unit displays the map data in a display format including an operation unit that displays details of the posted information item,

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

3. The in-vehicle display apparatus according to claim 1, wherein a plurality of classified posted information items classified by the category classifying unit, which are displayed so as to be selected by an operation of the display unit, are displayed, and

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

4. The in-vehicle display apparatus according to claim 3, wherein the display unit displays the plurality of classified posted information items that are edited in a list format in which the plurality of classified posted information items are arranged in time series on the basis of a post time, a list format in which the plurality of classified posted information items are arranged in ascending order of a distance from a position on the map data where an operation input is received, or a list format in which the plurality of classified 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 phrases related to the posted information item so as to be selectable and displays a selected fixed phrase at a 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 a season, time, weather, and taste of a 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 a direction of a position where a posted information item 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 on an in-vehicle display apparatus, comprising:

acquiring a plurality of posted information items which are posted by a plurality of users in real time and to which geographical location data indicating a destination of each of the plurality of posted information items is added;

specifying a posted information item to be displayed from the plurality of posted information items based on a hash tag included in each of the plurality of posted information items;

classifying the specified posted information item into categories, which are not categories by the geographical location data indicating the destination of the posted information item, based on the hash tag; and

displaying map data in which the classified specified posted information item is displayed, using a display method that is changed based on an elapsed time from the posting of the classified specified posted information item to the acquisition of the specified posted information, in a speech-bubble-type icon of a color which is specified according to a classified category at a position specified by the geographical location data which is acquired together with the classified posted information item, when the elapsed time from the posting of the classified specified posted information item to the acquisition of the classified specified posted information item that is acquired is less than a predetermined time.

10. An information display system comprising:

a communication apparatus that acquires a plurality of posted information items; and

a display apparatus that displays a the plurality of posted information items,

wherein the communication apparatus includes;

an information acquiring unit that acquires the plurality of posted information items which are posted by a plurality of users in real time and to which geographical location data indicating a destination of each of the plurality of posted information items is added; and
