- the menu hierarchy includes the top image of the selected link function.
- the object selection layer includes an image for selecting an execution object of the currently selected cooperation function.
- the active layer includes an image showing the execution status of the selected linkage function.
- each cooperation function that has a target selection hierarchy the transition from the menu hierarchy to the target selection hierarchy is performed based on a right short press input.
- the transition from the target selection layer to the active layer is performed based on the right short press input.
- the driver can intuitively transition between hierarchical levels. Also, switches other than direction switches such as decision switches are unnecessary.
- transitions from the active hierarchy to the object selection hierarchy and transitions from the object selection hierarchy to the menu hierarchy are performed based on a left short press input in the opposite direction to a right short press input. Therefore, the driver can intuitively return to the hierarchy.
- the mobile device 310 does not provide visual confirmation to the driver when transitioning from the menu hierarchy to the object selection hierarchy and transitioning from the object selection hierarchy to the active hierarchy.

- the control unit 311 may provide a voice message to the user in the processing of the cooperation function.
- step S1108 the control unit 311 determines whether or not an instruction to end cooperation has been acquired. If this instruction is acquired (YES in S1108), the control unit 311 shifts the process to step S1102, otherwise (NO in S1108), the control unit 311 shifts the process to step S1104. In the above example, the control unit 311 determines that an instruction to end cooperation has been obtained when a right long press input is received from the vehicle 100 .
- the mobile device 310 may have a function (that is, a skill level management function) of managing the user's skill level regarding the operation of the mobile device 310 . For example, if the mobile device 310 determines that the user is not accustomed to operating the mobile device 310, it sets the skill level of the user to a low level. Also, set the user proficiency to a high level. Mobile device 310 may provide messages to the user in a proficiency-based manner.
- a skill level management function that is, a skill level management function of managing the user's skill level regarding the operation of the mobile device 310 . For example, if the mobile device 310 determines that the user is not accustomed to operating the mobile device 310, it sets the skill level of the user to a low level. Also, set the user proficiency to a high level. Mobile device 310 may provide messages to the user in a proficiency-based manner.
- the mobile device 310 manages the user's proficiency in four levels from “0" to "3". The higher the proficiency value, the higher the proficiency (that is, the more accustomed to the operation). In the example of FIG. 12, the mobile device 310 provides different modes of providing messages for three items: "message content,” “message playback volume,” and “message playback speed.”
- the mobile device 310 provides a detailed message (eg, "Mr. Taro Honda is calling. Would you like to answer?"). If the skill level is higher than this (eg, "2"), mobile device 310 provides a message with simplified content (eg, "Incoming call from Mr. Taro Honda.”). If the skill level is higher (eg, "3"), the mobile device 310 provides a message (eg, "Mr. Taro Honda") that omits the fixed form. Since a user with a high level of skill can understand the specific contents only with a simple message, the user's operational feeling is improved by varying the contents of the message in this way.
- the mobile device 310 will provide the message at a high volume. If the mobile device 310 has a higher proficiency level (eg, '1' to '3'), the mobile device 310 will provide the message at a slightly louder volume. Since a user with a high skill level can grasp the contents of a message even at a low volume, the user's operational feeling is improved by varying the playback volume of the message in this way.
- a low proficiency level eg, "0”
- a higher proficiency level eg, '1' to '3'
- the mobile device 310 will provide the message at a slightly louder volume. Since a user with a high skill level can grasp the contents of a message even at a low volume, the user's operational feeling is improved by varying the playback volume of the message in this way.
- the mobile device 310 If the mobile device 310 has a low proficiency (eg, "0"), it will serve messages at a slow rate. The mobile device 310 speeds up message playback as it gains proficiency. Since a highly skilled user can grasp the contents of a message even at a high speed, by varying the playback speed of messages in this way, the user's operational feeling is improved.
- a low proficiency eg, "0”
- the mobile device 310 speeds up message playback as it gains proficiency. Since a highly skilled user can grasp the contents of a message even at a high speed, by varying the playback speed of messages in this way, the user's operational feeling is improved.
- the mobile device 310 changes the proficiency level based on the number of operations in a series of operations performed by the user to transition the mobile device 310 from the start state to the end state.
- a starting state is the state of the mobile device 310 when a series of operations is started.
- An end state is a state of the mobile device 310 that transitions due to the end of a series of operations.
- the user's operation on the mobile device 310 may be an operation performed on the input unit 315 of the mobile device 310, or may be an operation performed through the direction input unit 305 of the vehicle 100. The operation may be performed through the microphone 321 of the headset 320 .
- the starting point of one operation is transition from a state in which the user is not performing any operation on the mobile device 310 to a state in which the user is performing some operation (for example, pressing a button) on the mobile device 310. It can be a point in time.
- the end point of one operation is transition from a state in which the user is performing some operation (for example, pressing a button) on the mobile device 310 to a state in which the user is not performing any operation on the mobile device 310. It can be a point in time. Therefore, in the series of operations, a state in which the user is performing some operation (for example, pressing a button) on the mobile device 310 and a state in which the user is not performing any operation on the mobile device 310 alternately. occurs in
- a user performs a series of operations on the mobile device 310 for some purpose (for example, to make a call).
- a series of operations after a predetermined period of time (for example, one minute or more) has passed since the previous operation of the mobile device 310 by the user is initiated by the user for a new purpose different from the purpose of the previous operation. considered to be an operation. Therefore, the series of operations may start from the first operation after a predetermined period of time (for example, one minute or more) has passed since the previous operation of the mobile device 310 by the user.
- the user may perform a series of operations for another purpose (e.g., to initiate route guidance).
- a series of operations may be performed on the mobile device 310; Therefore, the series of operations may start from the first operation after the mobile device 310 performs specific processing (for example, making a call, starting route guidance, starting music playback, etc.) by user's operation.
- specific processing for example, making a call, starting route guidance, starting music playback, etc.
- a series of operations may end with the last operation performed by the mobile device 310 to execute a specific process (for example, making a call, starting route guidance, starting music playback, etc.) by user's operation. Also, the user may terminate a series of operations without performing specific processing. For example, there is a case where a series of operations is started with the intention of executing a specific process, but the series of operations ends without reaching the specific process. Therefore, the end point of the series of operations may be the last operation in which no subsequent operation is performed for a predetermined period of time (for example, one minute or longer).
- the current state of the mobile device 310 is the state in which the music playback function menu is selected (the image 504 is displayed). Then, from this state, the user performs a series of operations on the mobile device 310 in order to execute the calling function.

- a user who is not sufficiently familiar with operating the mobile device 310 transitions the mobile device 310 from the start state to the end state, as indicated by path 1302, for example. Specifically, the user transitions the mobile device 310 to a state in which music search is possible (a state in which the image 802 is displayed) by performing a right short press input once. The user who notices the operation error returns the mobile device 310 to the state in which the menu of the music playback function is selected (the state in which the image 504 is displayed) by performing a short left press input once. The user then transitions the mobile device 310 to the calling state in a manner similar to path 1301 . In this example, the user transitions the mobile device 310 from the start state to the end state by seven press input operations and one voice input operation.
- a user who is almost unfamiliar with operating the mobile device 310 transitions the mobile device 310 from the start state to the end state, as indicated by path 1303, for example. Specifically, the user transitions the mobile device 310 to a state in which the menu of the messaging function is selected (a state in which the image 505 is displayed) by performing a short downward press input once. The user then transitions between states within the messaging function. The user who notices the operation error returns the mobile device 310 to the state in which the menu of the messaging function is selected (the state in which the image 505 is displayed), and then performs a short-up input to transition to another menu. do.
- the user does not stop at the call function menu, and shifts the mobile device 310 to the state in which the weather information provision function menu is selected (the image 501 is displayed). After that, the user transitions the mobile device 310 to the state in which the call function menu is selected (the state in which the image 502 is displayed), and transitions the mobile device 310 to the calling state in the same manner as the route 1301 . In this example, the user transitions the mobile device 310 from the start state to the end state with 13 press input operations and one voice input operation.
- the mobile device 310 increases the skill level if the number of operations in such a series of operations is small, and decreases the skill level if the number of operations in such a series of operations is large.
- the method may begin upon activation of mobile device 310 .
- Each step of the following operation is executed by the controller 311 of the mobile device 310 .
- the initial value of the skill level of the user may be the lowest level (“0” in the example of FIG. 12).
- the user's proficiency level is stored in a storage device (eg, memory 313) of mobile device 310 and is updated by the following operations.
- the user's proficiency level may be updateable to a user-specified value.
- step S1401 the control unit 311 determines whether a series of operations has started. If a series of operations has started (“YES” in step S1401), the control unit 311 causes the process to proceed to step S1402, otherwise ("NO” in step S1401), repeats step S1401.
- the control unit 311 causes the mobile device 310 to perform a specific process ( For example, it may be determined that a series of operations has started when an operation is performed after executing a call, route guidance start, music playback, etc.).
- the control unit 311 starts counting the number of times the mobile device 310 is operated by the user.
- the operations to be counted may be all operations on the mobile device 310 (for example, pressing input operations, voice input operations, etc.).
- the operations to be counted may be partial operations on the mobile device 310 .
- the operation to be counted may be an operation by a specific input method (for example, press input) or an operation by a specific input device (for example, direction input unit 305 of vehicle 100).
- step S1403 the control unit 311 determines whether the series of operations has ended. If the series of operations has ended ("YES” in step S1403), the control unit 311 shifts the process to step S1404, otherwise ("NO” in step S1403), repeats step S1403.
- the control unit 311 determines whether a new operation has not been performed for a predetermined time or longer (for example, 1 minute or longer) since the last operation of the mobile device 310 by the user, or when the mobile device 310 is in a specific state due to the last operation of the user. It may be determined that the series of operations has ended when processing (for example, making a call, starting route guidance, starting music playback, etc.) is executed.
- the control unit 311 finishes counting the number of operations started at step S1402.
- the control unit 311 stores this number of operations in a storage unit (for example, the memory 313) for subsequent processing.
- a storage unit for example, the memory 313.
- the number of operations is 6 (5 press input operations and 1 voice input operation).
- the number of operations is 8 (7 press input operations and 1 voice input operation). and one voice input operation).

- step S1405 the control unit 311 determines whether or not the user has passed through an unnecessary cooperation function through a series of operations.
- the control unit 311 shifts the process to step S1412 if the series of operations has passed through an unnecessary link function ("YES” in step S1405), otherwise ("NO” in step S1405).
- the process transitions to S1406.
- An unnecessary link function is a function that does not need to be passed through in order to transition the mobile device 310 from the start state to the end state among the plurality of link functions. For example, in the example of FIG. 13, route 1303 goes through the messaging function and the weather information providing function. As indicated by a route 1301, the messaging function and the weather information providing function are unnecessary cooperative functions because the transition to the originating state can be made without going through these cooperative functions.
- step S1406 the control unit 311 sets a reference range for determining whether to change the skill level based on the minimum number of operations required to transition the mobile device 310 from the start state to the end state. As will be described later, this reference range is compared with the number of operations in a series of user operations. In the example of FIG. 13, the minimum number of operations is six (five press input operations and one voice input operation). The minimum number of operations required to transition the mobile device 310 from the start state to the end state may be calculated by searching a state transition diagram representing the states of the mobile device 310 from the start state to the end state using a breadth-first search. .
- the reference range is set to be the standard number of operations for each proficiency level. In other words, a user who transitions the mobile device 310 from the start state to the end state by operating the mobile device 310 less than the reference range is considered to be familiar with the operation, and the user moves the mobile device 310 from the start state to the end state by operating the mobile device 310 more times than the reference range. A user who has transitioned to is considered to be unfamiliar with the operation.
- the control unit 311 may set the upper limit value and the lower limit value of the reference range based on the minimum number of operations required to transition the mobile device 310 from the start state to the end state.
- control unit 311 may set the upper and lower limits of the reference range by applying the minimum number of operations to another function. At least one of the upper limit value and the lower limit value of the reference range may not be based on the minimum number of operations, and may be a value calculated according to another reference or a fixed value.
- the upper limit of the reference range is twice the minimum number of operations
- the lower limit of the reference range is 1.3 times the minimum number of operations.
- the minimum number of operations is six. Therefore, the reference range is 7.8 times or more and 12 times or less. Since the number of operations in the series of operations on path 1301 is 6, this number of operations is below the reference range. Since the number of operations in the series of operations on path 1302 is 8, this number of operations is included in the reference range. Since the number of operations in the series of operations on path 1303 is 14, this number of operations exceeds the reference range.
- the control unit 311 may set the reference range based on the user's current skill level. For example, each of the upper limit and lower limit of the reference range may be set to a lower value as the user's current skill level increases. As a result, a user with a low skill level increases his skill level when he gets used to operating the mobile device 310 a little, and a user with a medium skill level increases his skill level when he gets more used to operating the mobile device 310 . degree increases.
- step S1407 the control unit 311 determines whether or not the number of operations in the series of operations exceeds the upper limit of the reference range. If the number of operations in the series of operations exceeds the upper limit of the reference range ("YES" in step S1407), the control unit 311 shifts the process to step S1412; otherwise ("NO” in step S1407). , the process transitions to step S1408.
- step S1408 the control unit 311 determines whether or not the number of operations in the series of operations is below the lower limit of the reference range.
- the control unit 311 shifts the process to step S1409 if the number of operations in the series of operations is below the lower limit of the reference range ("YES” in step S1408), otherwise ("NO” in step S1408). , the process transitions to step S1401.
- a determination of "NO” is made in step S1408 when the user has not passed through unnecessary link functions due to a series of operations and the number of operations is within the reference range. In such a case, the control unit 311 determines that the current skill level is appropriate, and waits for the next series of operations without performing processing for changing the skill level.
- step S1409 the control unit 311 increments the skill level change count value by one.
- the initial value of this count value is, for example, 0, and is increased or decreased in step S1409 and step S1412 described later.
- the control unit 311 resets the count value for changing the skill level to the initial value.
- Step S ⁇ b>1409 is executed when the user does not go through an unnecessary link function by a series of operations and the number of operations falls below the lower limit of the reference range. In such a case, the control unit 311 determines that the user is accustomed to the operation with respect to the current skill level, and performs processing for increasing the skill level.
- step S1410 the control unit 311 determines whether or not the count value for changing the skill level has reached the increase threshold. Control unit 311 shifts the process to step S1411 if the count value for changing skill level has reached the rising threshold ("YES" in step S1410), otherwise ("NO” in step S1410). to step S1401.
- step S1411 the control unit 311 increases the skill level of the user. For example, the control unit 311 raises the user's proficiency level by one level. If the user's proficiency level is already at the highest level, the control unit 311 does not change the proficiency level.
- the increase threshold used in step S1410 is a value for increasing the skill level, and may be "5", for example.
- the increase threshold may be a different value for each skill level.
- the increase threshold for increasing the skill level from “0" to “1” may be 10, and the increase threshold for increasing the skill level from "1" to “2" may be 5.
- step S1412 the control unit 311 decrements the skill level change count value by one.
- Step S1412 is executed when a series of operations by the user goes through an unnecessary link function, or when the number of operations exceeds the upper limit of the reference range. In such a case, the control unit 311 determines that the user is not accustomed to the operation with respect to the current skill level, and performs processing for decreasing the skill level.
- control unit 311 determines whether or not the count value for changing the skill level has reached the decrease threshold. Control unit 311 shifts the process to step S1414 if the count value for changing skill level has reached the decrease threshold ("YES" in step S1413), otherwise ("NO” in step S1413). to step S1401. In step S1414, control unit 311 decreases the skill level of the user. For example, the control unit 311 decreases the user's proficiency level by one level. If the user's proficiency level is already at the lowest level, the control unit 311 does not change the proficiency level.
- the decrease threshold used in step S1413 is a value for decreasing the skill level, and may be "-5", for example.
- the decrease threshold may be a different value for each skill level.
- the decrease threshold for decreasing the proficiency level from "3" to "2" may be -5
- the decrease threshold for decreasing the proficiency level from "2" to "1" may be -10. .
- the skill level is changed based on the number of operations performed by the user in a series of operations for transitioning the mobile device 310 from the start state to the end state, the skill level is adjusted appropriately according to the user's operation level. can be set to
- both the skill level increase (step S1411) and the skill level decrease (step S1414) are performed.
- the control unit 311 may perform only one of increasing the proficiency level and decreasing the proficiency level in the above-described method.
- the control unit 311 may only decrease the skill level based on the number of operations in a series of operations as described above, and may increase the skill level based on other criteria. You don't have to.
- one count value for changing the skill level is increased or decreased (steps S1409 and S1412).
- the control unit 311 may separately manage the skill increase count value to be increased in step S1409 and the skill decrease count value to be decreased in step S1412.
- the control unit 31 when at least one of the fact that the user has passed through an unnecessary link function by a series of operations and the fact that the number of operations exceeds the upper limit value of the reference range, determines whether to change the skill level. is decremented by one. Instead of this, the control unit 311, when both the fact that the user has passed through an unnecessary link function by a series of operations and the fact that the number of operations exceeds the upper limit value of the reference range, the control unit 311 The count value may be decremented by one.
- the count value for skill level change is decremented by 1 based on the fact that the user has gone through an unnecessary linking function through a series of operations.
- the control unit 311 may omit S1405 and change the proficiency level regardless of whether or not the user has passed through unnecessary cooperation functions in a series of operations.
- the control unit 311 may be able to determine whether the user is driving the vehicle 100 or not. For example, the control unit 311 may query the vehicle 100 whether the user is driving the vehicle 100 and make this determination based on the response. The control unit 311 may determine that the user is not driving the vehicle 100 when the speed of the vehicle 100 is equal to or less than a threshold value (for example, 1 km/h or less or 0 km/h or less). The control unit 311 may acquire the speed of the vehicle 100 from the vehicle 100 or may regard the moving speed of the mobile device 310 as the speed of the vehicle 100 .
- a threshold value for example, 1 km/h or less or 0 km/h or less.
- the control unit 311 manages the skill level separately when the user is driving the vehicle 100 and when the user is not driving the vehicle 100 (for example, when the vehicle 100 is stopped). may Even if the user becomes accustomed to operating the mobile device 310 when not driving the vehicle 100, the user may not be able to operate the mobile device 310 with the same level of proficiency while driving. Therefore, by managing the skill level separately for the case of driving and the case of not driving, the user's operational feeling is improved.
- the mobile device 310 stores, in its own storage device (for example, the memory 313), the skill level for operations while driving and the skill level for operations other than while driving.
- the control unit 301 changes the skill level for the operation while driving in step S1411 or S1414.
- the control unit 301 provides the message in a mode according to the skill level of the operation during driving.
- the control unit 301 changes the skill level for operations other than driving in step S1411 or S1414.
- control unit 301 when providing a message to a user other than driving, the control unit 301 provides the message in a mode according to the level of skill with respect to operations other than driving.
- the counting started in step S1402 is also managed separately depending on whether the vehicle is in operation or not.
- the skill level management function has been described in the context of the cooperation function between the vehicle 100 and the mobile device 310. Instead, the skill level management function of the present invention may be applied to the function of cooperation between the vehicle 100 and other devices, the function of the vehicle 100 alone, or a combination thereof. may be
