INFORMATION DISPLAY SYSTEM, INFORMATION DISPLAY DEVICE, AND INFORMATION PROVIDING DEVICE
Disclosed is a display system capable of achieving a prompt drive-forced function even in an environment where, as in a remote UI, a delay occurs until a change by an information providing device is reflected in an information display device. This display system is provided with an information providing device ( 101 ) and an information display device ( 111 ), said information providing device ( 101 ) comprising a communication section “a” ( 104 ) and an accumulation section ( 102 ) which accumulates scripts ( 103 ) that include displayed parts constituting displayed images and the arrangement thereof, descriptions of animation movements etc. of the displayed parts, and drive-forced flags for all of the displayed parts, and said information display device ( 111 ) comprising a communication section “b” ( 112 ), a script processing section ( 113 ), a display section ( 114 ), and a sensor determination section ( 115 ).
1 . An information display system that is installed in a vehicle, the information display system comprising:
an information providing apparatus that transmits a script of a display part;
an information display apparatus that interprets a script transmitted by the information providing apparatus and displays a composed display image; and
a sensor determination apparatus that reports a driving state of the vehicle to the display apparatus, wherein:
the display part can change between at least two display states of normal display and drive-forced display; and
the information display apparatus changes a display state of the display part based on a report result from the sensor determination apparatus.
2 . The information display system according to claim 1 , wherein the information display apparatus, when the fact that the vehicle is driving is reported to the information display apparatus from the sensor determination apparatus and a display state of the display part is normal display, changes a display state of a display part to drive-forced display.
3 . The information display system according to claim 1 , wherein:
a script transmitted to the information display apparatus by the information providing apparatus includes a drive-forced flag indicating a driving state provided for the display part; and
the information display apparatus changes a state of a display part based on a driving state reported from the sensor determination apparatus and the drive-forced flag.
4 . The information display system according to claim 3 , wherein the drive-forced flag is provided only for a display part used for operation of a function that is operable when the vehicle is stationary and that is inoperable when the vehicle is driving.
5 . The information display system according to claim 1 , wherein:
the information display apparatus further comprises a script storing section that stores a script transmitted by the information providing apparatus; and
the information display apparatus reads a script stored in the script storing section in accordance with a state of a display part for which a display state has been changed, and composes and displays a display image.
6 . An information display apparatus that is installed in a vehicle, and is connected to an information providing apparatus that transmits a script of a display part composing a display image, and a sensor determination apparatus that reports a driving state of the vehicle to the display apparatus, the information display apparatus comprising:
a script processing section that interprets a script transmitted by the information providing apparatus and receives a report from the sensor determination apparatus; and
a display section that displays a display image interpreted and composed by the script processing section, wherein the display part is changeable to at least two display states of normal display and drive-forced display, and when the fact that the vehicle is driving is reported to the script processing section from the sensor determination apparatus and a display state of the display part is the normal display, the script processing section changes a display state of the display part to the drive-forced display.
7 . The information display apparatus according to claim 6 , wherein the sensor determination apparatus is provided inside the information display apparatus.
8 . The information display apparatus according to claim 6 , wherein:
a script transmitted from the information providing apparatus includes a drive-forced flag indicating a display state that is provided for the display part; and
the information display apparatus changes a state of a display part based on a driving state reported from the sensor determination apparatus and the drive-forced flag.
9 . The information display apparatus according to claim 8 , further comprising an input section that receives operation input from a user, wherein the input section, when having received operation input from a user, restricts operation input based on information reported from the sensor determination apparatus.
10 . The information display apparatus according to claim 6 , further comprising a script storing section that stores a script transmitted by the information providing apparatus, wherein the script processing section reads a script stored in the script storing section, and composes and displays a display image of the drive-forced display.
11 . An information providing apparatus that is installed in a vehicle, the information providing apparatus comprising a storage section that stores a script to be transmitted to an information display apparatus that interprets a script and displays a composed display image, wherein a script stored in the storage section includes a display part capable of changing between at least two display states of normal display and drive-forced display.
