Further, a registered operation is a function assigned independently of a function assigned to a single operation constituting a registered command.

Description

  The present invention relates to an input operation of a navigation device.

  A user who uses a navigation device often performs other operations at the same time. For example, in the case of a pedestrian navigation device realized by a portable terminal or the like, a user may use it while holding it in his / her hand. In addition, a car navigation device mounted on a vehicle may be used by a driving user.

  Therefore, it is desirable that the navigation device can be easily operated. As a navigation device that can be operated easily, there has conventionally been a navigation device that performs a function switching operation by voice recognition. For example, Patent Document 1 discloses a navigation device that recognizes a user's utterance content, extracts a place name, and scrolls a map screen toward a facility having the place name as a part of the facility name. As another method, there is a navigation device having shortcut buttons to which various functions are assigned in advance (see Patent Document 2).

JP 2007-279537 A JP 2010-276501 A

  However, switching of functions by speech recognition as in Patent Document 1 has a problem that it takes time and there is a recognition error.

  Further, in the method of Patent Document 2 in which the navigation device is operated using the shortcut button, it is necessary to move the line of sight to input and it is particularly difficult to perform while driving the vehicle. Furthermore, there is a problem that the types of operations that can be performed depend on the number of shortcut buttons.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a navigation apparatus that can easily input various types of commands.

  The navigation device of the present invention receives an operation receiving unit that receives an operation of an input device, a registration command that indicates a permutation of a plurality of operations that is predetermined from a plurality of types of operations of the input device, and a registration command that is executed When a plurality of operations are input from the input device to the operation receiving unit, the registration command information acquisition unit that acquires the registration command information indicating the correspondence with the registration operation that is to be performed An input command analysis unit that searches for a corresponding registration operation that is a registration operation corresponding to a registration command that matches an input command that is a permutation of input operations, and an operation execution unit that executes the corresponding registration operation. Is a function assigned independently of the function assigned to the single operation constituting the registration command.

<A. Embodiment 1>
<A-1. Configuration>
FIG. 1 is a block diagram illustrating a configuration of a navigation device 10 according to the first embodiment. In the following description, the navigation device 10 will be described as a car navigation device mounted on a vehicle.

  The navigation device 10 includes an operation reception unit 11, an input command analysis unit 12, a registered command information storage unit 13, an operation execution unit 14, a drawing control unit 15, and a failure notification unit 16.

  The operation receiving unit 11 receives an input operation of the input device 1. The input device 1 includes a normal input device 2 that performs a normal input operation and a command input device 3 that performs a command input operation. The normal input device 2 is configured by, for example, a mechanical switch or a touch panel, and may be configured by a remote control that is separate from the navigation device 10. The normal input operation refers to an input operation other than the command input operation.

  The command input device 3 is realized by, for example, a joystick as shown in FIG. According to the joystick, the user can operate by tilting or rotating the lever in a predetermined direction such as left, right, up, down, or diagonally, so that the user can only feel the hand without directing the line of sight to the operation. The operation can be performed. Therefore, even if the vehicle is in operation, it can be operated safely.

  In this specification, continuous operation by the command input device 3 is referred to as command input operation, and a sequence of a plurality of operations performed continuously is referred to as an input command.

  Note that the normal input device 2 and the command input device 3 may be configured as separate devices or may be configured as the same device. For example, a normal input operation may be performed with a joystick that implements the command input device 3. That is, the command input device 3 does not need to be used only for command input operations that perform operations continuously, and can also be used as an input device that performs input by a single input operation, for example.

  The registered command information storage unit 13 stores registered command information indicating a correspondence relationship between a plurality of input commands for the navigation device 10 and functions executed by the commands. In the following description, the name “registered command” is used to mean an input command to which a function to be executed is assigned (registered). The registered command information storage unit 13 is realized by a storage medium such as a hard disk drive (HDD) or a flash memory. The registration command information may be stored in advance before product shipment of the navigation device 10 or may be arbitrarily stored by the user. Further, instead of the registration command information storage unit 13 constantly storing the registration command information, the navigation device 10 may acquire the registration command information stored in the external server or the like as necessary. The registration command information storage unit 13 is also referred to as a registration command information acquisition unit 13.

  The input command analysis unit 12 analyzes the input command received from the command input device 3 by the operation reception unit 11. Specifically, the input command analysis unit 12 acquires registration command information from the registration command information storage unit 13 and searches for a registration command that matches the input command.

  The operation execution unit 14 executes the operation assigned to the input command according to the search result of the input command analysis unit 12. Further, when the operation receiving unit 11 receives a normal operation, an operation corresponding to the operation is executed.

  The drawing control unit 15 draws a display image of the display device 5.

  The failure notification unit 16 informs that the command input operation has failed when the registration command matching the input command is not stored in the registration command information storage unit 13 as a result of the search in the input command analysis unit 12. The output device 4 generates voice information for notifying the user.

  The operation reception unit 11, the input command analysis unit 12, the operation execution unit 14, the drawing control unit 15, and the failure notification unit 16 are realized by a CPU that executes a program stored in a memory. The drawing control unit 15 is realized by a CPU or a GPU that executes a program stored in a memory.

<A-2. Operation>
FIG. 3 is a flowchart showing the operation of the navigation device 10. When the navigation apparatus 10 is turned on, the operation receiving unit 11 first determines whether or not a command input start notification has been received (step S1). For example, a command input start notification is input to the operation reception unit 11 by performing a predetermined command input start operation with the normal input device 2 or the command input device 3 before the user inputs a command. If the command input start notification has not been received in step S1, the process waits until the command input start notification is received.

  When receiving the command input start notification, the operation reception unit 11 determines that the input after the notification is a command input. Then, it is determined whether or not the navigation device 10 is in a state where a command can be input (step S2). The command input enabled state means a state in which a function corresponding to the input command can be executed. For example, if the display device 5 is currently displaying a telephone screen and the display is set to be fixed on the telephone screen during a telephone call, the screen cannot be changed in response to an input command. Therefore, it is not in a state where commands can be input. If the navigation device 10 determines that the command input is not possible, the failure notification unit 16 creates audio information for notifying that the command input operation has failed, and outputs the audio from the audio output device 4 to notify the failure notification. Perform (step S8). Then, the process ends.

  When the navigation device 10 is in a state where a command can be input in step S2, the operation reception unit 11 transitions to a command input waiting state and receives an input command (step S3). Here, the operation reception unit 11 stores a plurality of operations input from the command input device 3 in the order of input. Next, the operation reception part 11 judges whether it is input time-out (step S4). Here, if a predetermined period has elapsed since the command input start notification was received, it is determined that the input timed out. If it is not an input time-out, it is determined whether or not a command input completion notification has been received (step S5). For example, a command input completion notification is input to the operation reception unit 11 by performing a specific operation with the normal input device 2 or the command input device 3 after the user has finished inputting the command. If the command input completion notification has not been received yet, the process returns to step S3 and continues to accept input commands.

  If it is determined in step S4 that the input has timed out, or if it is determined in step S5 that there is a command input completion notification, the operation reception unit 11 ends the reception of the input command.

  Next, the input command analysis unit 12 determines whether or not the permutation (input command) of the plurality of operations received by the operation receiving unit 11 in step S3 is valid (step S6). Specifically, the registration command information in the registration command information storage unit 13 is referred to, and if a command that matches the input command is registered, it is determined that the input command is valid.

  FIG. 4 shows an example of registration command information. The registration command “left / right / left / right” is assigned an operation of “transition to phone screen”. This is a command input by an operation of continuously tilting the joystick left, right, left, right. In addition, an operation of “transition to navigation screen” is assigned to the registration command “upper right lower”.

  Now, let the input command in step S3 be “left, right, left”. That is, a command is input by an operation of tilting the joystick continuously to the left, right, left, and right. According to the example of FIG. 4, “left / right / left / right” is registered in the registration command information, and the corresponding operation is “transition to phone screen”.

  Therefore, the input command analysis unit 12 determines that the input command is valid (Yes in step S6), and the operation execution unit 14 executes “transition to telephone screen” (step S7). Specifically, the operation execution unit 14 instructs the drawing control unit 15 to draw a telephone screen. The drawing control unit 15 draws a telephone screen in response to an instruction from the operation execution unit 14, and the telephone screen is displayed on the display device 5.

  FIG. 5 shows a display screen transition example in the display device 5. When a command “left / right / left / right” is input with a joystick while a navigation screen for displaying a map or the like is displayed on the display device 5 (FIG. 5A), the display screen of the display device 5 is changed from the navigation screen to the telephone screen. (FIG. 5B).

  The registration command is not an operation that continuously assigns a single operation such as “left” or “right” that constitutes the registration command, but is independent of an operation assigned to a single operation. An action is assigned. In other words, the navigation device 10 does not transition to the telephone screen even if “left”, “right”, “left”, and “right” are input as normal operations, but “right, left, right” is input as an input command. The navigation device 10 transitions to the telephone screen.

  In step S6, if there is no registration command that matches the input command, it is determined that the input command is invalid. In that case, the failure notifying unit 16 creates audio information for notifying that the command input operation has failed, and outputs the audio from the audio output device 4 to notify the failure (step S8). Then, the process ends. In addition, when execution of a command fails in step S7, you may make it perform failure notification.

  As described above, in the navigation device 10 according to the present embodiment, the permutation of a plurality of operations performed by the command input device 3 is used as a registration command, and operations to be executed are assigned. A large number of registration commands that are not limited to a number can be prepared. That is, many types of registration commands that are not limited by the number of types of operations performed by the command input device 3 can be input to the navigation device 10.

<A-3. Modification>
The operator who performs the command input operation may be recognized, and different operations may be assigned to the registration command depending on the operator. FIG. 6 is a block diagram illustrating a configuration of a navigation device 10A that performs the above-described operator recognition. In the navigation device 10A, in addition to the configuration of the navigation device 10, the operation reception unit 11 includes an operator determination unit 17, and the registration command information storage unit stores separate registration command information for each operator. . Since the configuration other than this is the same as that of the navigation device 10, the description thereof is omitted.

  When the operation receiving unit 11 receives an input command from the command input device 3, the operator determining unit 17 determines the operator who is inputting the input command. In this case, for example, the command input device 3 includes a command input start notification button for a driver and a command input start notification button for a passenger on the passenger seat. When the user presses these buttons, the command input start notification is displayed as operator information. At the same time, it may be input to the operation receiving unit 11.

  The operator discriminating unit 17 discriminates which one of the driver and the passenger on the passenger seat has performed the command input operation from the operator information. The input command analysis unit 12 analyzes the input command using registered command information corresponding to the operator. According to such a configuration, different operations can be assigned to the same command for the driver and the passenger on the front passenger seat, and both can be used conveniently.

  In the above description, a joystick is taken as an example of the command input device 3. According to the joystick, since the operation can be performed without directing the line of sight to the operating hand, for example, it is not necessary to deflect the line of sight from the front of the vehicle even when the vehicle is being driven, and the operation can be performed safely. However, the command input device 3 may be realized by another operation device having the same effect. For example, a handle switch attached to the handle 20 as shown in FIG. The handle switch shown in FIG. 7 is a cross switch that can be operated using a fingertip even when the handle is held. Since the number of switches is as small as four, even a driving user can input a command by relying on the sense of the fingertip without directing his gaze at the handle switch.

  The navigation device 10 has been described as a car navigation device mounted on a vehicle. However, the navigation apparatus 10 may be constructed as a system in which a PND (Portable Navigation Device), a mobile terminal (for example, a mobile phone, a smartphone, a tablet, and the like), a server, and the like are appropriately combined. In this case, each component of the navigation device 10 is distributed and arranged in each device that constructs the system.

<A-4. Effect>

  In addition, the navigation device 10 according to the first embodiment normally uses a permutation of a plurality of operations input from the input start operation to a predetermined input completion operation of the input device 1 as an input command. A distinction is made between operations and command input operations. Alternatively, the normal operation and the command input operation may be distinguished by using a permutation of a plurality of operations input within a predetermined time from the most recent operation as an input command, or may be determined in advance from the input start operation.

Refer to any registered command information for the user and search for the operation. According to such a configuration, different operations can be assigned to the same command for the driver and the passenger on the front passenger seat, and both can be used conveniently.

  In the navigation device 10 according to the first embodiment, the operation receiving unit 11 determines whether or not the input command can be received, and receives the input command only when it is determined that the input command can be received. Includes a failure notification unit 16 that searches for an operation corresponding to a registered command that matches the input command received by the operation reception unit 11 and performs a voice notification when the operation reception unit 11 does not receive the input command. Can know that the command input operation failed.

  Alternatively, the failure notification unit 16 may perform voice notification when the registration command information does not contain a registration command that matches the input command as a result of the search by the input command analysis unit 12. Thereby, the user can know that the command input operation has failed.

  In addition, if the user can arbitrarily set the registration command of the registration command information and the corresponding operation, the usability of the user is improved.
