In-car information system, in-car device, and information terminal
An information terminal includes: an operation assignment information storage unit that stores operation assignment information; an actuation information reception unit that receives from an in-car device actuation information; an assignment unit that, on the basis of the operation assignment information and the actuation information, assigns some among a plurality of operations in the information terminal to each of one or more actuations among a plurality of types of actuation that can be inputted with an actuation unit provided to the in-car device respectively, according to priority levels; an actuation signal reception unit that receives an actuation signal outputted from the in-car device; and a conversion unit that, on the basis of the result of assignment by the assignment unit, converts the actuation signal into an operating command that corresponds to one among the plurality of operations.
1. An in-car information system comprising an information terminal and an in-car device that is connected to the information terminal so as to be capable of communicating with the information terminal, wherein:
a plurality of applications including a first application that is capable of starting corresponding to a type of the in-car device via an actuation unit provided to the in-car device and a second application that is incapable of starting via the actuation unit are stored in the information terminal;
the information terminal generates menu screen information for displaying an icon corresponding to the first application upon a display unit provided to the in-car device in a state that information for displaying an icon corresponding to the second application is not included in the menu screen information; and
the information terminal comprises a control unit that transmits the generated menu screen information to the in-car device and that executes the first application selected by an actuation of the actuation unit.
2. An in-car information system according to claim 1 , wherein the actuation unit is configured by a touch panel.
3. A menu screen generation method for an in-car information system comprising an information terminal and an in-car device that is connected to the information terminal so as to be capable of communicating with the information terminal, comprising:
a step of determining a first application that is capable of starting corresponding to a type of the in-car device via an actuation unit provided to the in-car device from among a plurality of applications stored in the information terminal; and
a step of generating menu screen information for displaying an icon corresponding to the first application upon a display unit provided to the in-car device in a state that information for displaying an icon corresponding to a second application that is incapable of starting via the actuation unit is not included in the menu screen information.
4. A menu screen generation method according to claim 3 , wherein the actuation unit is configured by a touch panel.
5. A menu screen generation method according to claim 3 , wherein generation of the menu screen information is stopped after the first application is started via the actuation unit of the in-car device.
6. A menu screen generation method according to claim 3 , wherein generation of the menu screen information is executed in a background of the information terminal or put into a state of sleeping after the first application is started via the actuation unit of the in-car device.
