Abstract

An in-vehicle display system is installed in a vehicle for displaying information to a user. The system includes a display unit that displays information; an operation unit that is located separately from the display unit and that allows a user to perform user operations including a directional operation and a turning operation; and a receiver that receives user instructions for making entry of plural characters that can be displayed on the display unit, based on displayed content displayed on the display unit and the user operations made with the operation unit. The receiver receives: (i) a first one of the directional operation and the turning operation as the user instruction in order to select a group from amongst a plurality of groups displayed on the display unit each of the plurality of groups representing a plurality of characters which are candidates for entry, and (ii) a second one of the directional operation and the turning operation as the user instruction in order to select a character from amongst the plural characters included in the group that is selected by the first one of the directional operation and the turning operation.

Claims

1. An in-vehicle display system for installation in a vehicle, the system comprising:

a display unit that displays information;

an operation unit that is located separately from the display unit and that allows a user to perform user operations including a directional operation and a turning operation; and

a receiver that receives user instructions for making entry of plural characters that can be displayed on the display unit, based on displayed content displayed on the display unit and the user operations made with the operation unit,

the receiver receiving;

(i) a first one of the directional operation and the turning operation as the user instruction in order to select a group from amongst a plurality of groups displayed on the display unit each of the plurality of groups representing a plurality of characters which are candidates for entry, and

(ii) a second one of the directional operation and the turning operation as the user instruction in order to select a character from amongst the plural characters included in the group that is selected by the first one of the directional operation and the turning operation.

2. The in-vehicle display system of claim 1, wherein

the receiver receives the directional operation as the user instruction for selecting the group, and receives the turning operation as the user instruction for selecting the character that is included in the group that is selected.

3. The in-vehicle display system of claim 2, wherein

the display unit displays the plurality of groups in a two-dimensional array.

4. The in-vehicle display system of claim 2, wherein

the display unit displays at least some of the plural characters included in the group that is selected by the directional operation in a circular pattern.

5. The in-vehicle display system of claim 1, wherein

the display unit displays at least some of the plural characters included in the group that is selected, and does not display at least some of the plural characters included in the groups that are not selected from amongst the plurality of groups.

6. The in-vehicle display system of claim 1, wherein

the operation unit includes one controller member by which the user performs both of the turning operation and the directional operation.

7. The in-vehicle display system of claim 6, wherein

the receiver receives the user instruction given by the turning operation in preference to the user instruction given by the directional operation.

8. The in-vehicle display system of claim 1, wherein

the plural characters include Japanese characters.

9. The in-vehicle display system of claim 7, wherein:

the receiver waits a predetermined time period after receipt of the turning operation before accepting the directional operation.

10. The in-vehicle display system of claim 9, wherein:

the predetermined time period is between about 0.3 seconds and about 1.0 seconds.

11. The in-vehicle display system of claim 1, wherein:

the display unit displays the plurality of groups as selectable items without displaying all of the plurality of characters which are candidates for entry.

12. The in-vehicle display system of claim 1, wherein:

before the first one of the directional operation and the turning operation is received, the display unit displays the plurality of groups as selectable items, and

after the first one of the directional operation and the turning operation is received, the display unit continues to display the plurality of groups as selectable items, while displaying the plural characters included in the group selected by the first one of the directional operation and the turning operation.
