Japanese Unexamined Patent Publication No. 2004-046459 Japanese Unexamined Patent Publication No. 2013-097413 Japanese Unexamined Patent Publication No. 2012-142719 Japanese Unexamined Patent Publication No. 2004-157799 Japanese Unexamined Patent Publication No. 2005-198112 Japanese Unexamined Patent Publication No. 2016-024150 Japanese Unexamined Patent Publication No. 8-162864 Japanese Unexamined Patent Publication No. 11-017471

Conventionally, a user interface that allows a parameter setting to input an instruction for specifying a moving direction of a parameter has been widely used. As a problem common to these user interfaces, there is a problem that if the movement amount according to the input of the instruction is reduced, it takes time or effort to reach the target value, and if the movement amount is increased, the target value is jumped over.

In order to solve such problems, conventionally, the technology of continuously moving the parameter by setting the parameter movement amount to a small value and pressing and holding it, and the long-press movement amount using the elapsed time and the threshold value (See Patent Document 3), a technique for setting a smaller amount of movement when changing direction (see Patent Document 1), etc. have been proposed, but in order to reach the target value with less effort or time. Was not enough. It is also possible to adopt other user interfaces in order to reach the target value with less effort or time, but such a user interface is compared with an interface that only specifies the moving direction of parameters. It required complicated operations.

In view of the above problems, it is an object of the present disclosure to provide a parameter update method capable of reaching a target value with a small number of operations in a parameter movement operation using a simple user interface.

A reception means that accepts input of a movement operation including information that can specify the movement direction, a movement direction related to the current operation that is a new movement operation when a new movement operation is received by the reception means, and the previous movement direction. The direction determining means for comparing the movement direction related to the previous operation, which is a movement operation, and the movement direction related to the current operation and the movement direction related to the previous operation are the same, and at least the parameters after the movement are the estimated range. The movement amount setting means that increases the movement amount of the parameter according to the current operation when it is outside the above, and the movement amount set by the movement amount setting means, the movement amount corresponding to the new movement operation. It is an information processing apparatus including a parameter moving means for moving parameters.

The present disclosure can be understood as a method executed by an information processing device, a system, a computer, or a program executed by a computer. Further, the present disclosure can be grasped as if such a program is recorded on a recording medium that can be read by a computer or other device, a machine, or the like. Here, a recording medium that can be read by a computer or the like is a recording medium that can be read from a computer or the like by accumulating information such as data or programs by electrical, magnetic, optical, mechanical or chemical action.

Etc. may be executed by a device installed at a remote value or a plurality of devices installed in a distributed manner. The configuration of the information processing device 1 is not limited to the examples in the present embodiment.

Buttons 2a and 2b are buttons for designating the moving directions of parameters that can move in two or more different directions. For example, they instruct to increase or decrease parameters such as the set volume of the acoustic output device and the set temperature of the air conditioner. It is an increase button and a decrease button for. The buttons 2a and 2b are not limited to buttons that can be physically pressed. For example, the buttons 2a and 2b may be provided as software buttons displayed on the touch panel display, or may be provided as conceptual buttons whose operation is detected by a gesture or voice input by the user.

As described above, the parameters to be set in the present disclosure may be those that can move in two or more different directions, and are not limited to those in which the numerical value represented by a single index increases or decreases. Therefore, the parameters that can be set in the present disclosure may be those used as physical quantities such as volume, temperature, humidity, and brightness, as well as some set values (for example, coordinates, etc.) other than the physical quantities, and the parameter utilization device 3 Is not limited to an acoustic output device, an air conditioner, or the like. Further, the parameter utilization device 3 may output the parameter by display or the like so that the current value can be grasped by the user who sets the parameter (the display device or the like is not shown).

FIG. 2 is a diagram showing an outline of the functional configuration of the information processing apparatus according to the present embodiment. The information processing device 1 retains data by reading the program recorded in the storage device 14 into the RAM 13 and executing the program by the CPU 11 to control each hardware provided in the image data processing server 1. A device including a unit 21, a reception unit 22, a direction determination unit 23, a movement amount setting unit 24, an estimation range setting unit 25, and a parameter movement unit 26, and updating parameter values while changing the movement amount according to the operation context. Functions as. In the present embodiment, each function included in the information processing device 1 is executed by the CPU 11 which is a general-purpose processor, but a part or all of these functions may be executed by one or a plurality of dedicated processors. ..

The data holding unit 21 causes the RAM 13 to hold a predetermined parameter used by the parameter utilization device 3, and is also input to a newly input movement operation (hereinafter referred to as “current operation”) and one time before. For the movement operations (hereinafter referred to as "previous operations"), the movement directions, movement amounts, and parameters related to these operations are retained. Further, the data holding unit 21 causes the RAM 13 to hold an end value (upper end value and lower end value) indicating an estimated range in which the target value of the parameter desired by the user is estimated to be included.

FIG. 3 is a diagram showing the relationship between the parameter settable range and the estimated range in the present embodiment. In the present embodiment, among the parameters that can take an integer value between the minimum value (0) and the maximum value (127), the estimated range estimated to include the target value of the parameter by the user is the upper end value and the lower end value. Is determined by.

The reception unit 22 receives an input of a movement operation including information that can specify at least the movement direction, which is a parameter movement operation by the user.

When a new movement operation is received by the reception unit 22, the direction determination unit 23 compares the movement direction related to the current operation, which is a new movement operation, with the movement direction related to the previous operation, which is the previous movement operation. To do.

The movement amount setting unit 24 sets the movement amount of the parameter to be moved according to the current operation according to the expansion or contraction of the estimation range according to the user's operation intention estimated from the contents of the current operation and the previous operation. To do. For example, the movement amount setting unit 24 responds to the current operation when the movement direction related to the current operation and the movement direction related to the previous operation are the same and at least the parameters after the movement are out of the estimation range. Increase the amount of parameter movement. Further, the movement amount setting unit 24 reduces the movement amount of the parameter according to the current operation when the movement direction related to the current operation and the movement direction related to the previous operation are different.

The estimation range setting unit 25 sets (enlarges or reduces) the estimation range estimated to include the target value desired by the user of the parameter according to the operation intention of the user estimated from the contents of the current operation and the previous operation. Or move). For example, the estimation range setting unit 25 expands the estimation range when the movement direction related to the current operation and the movement direction related to the previous operation are the same and at least the parameters after the movement are outside the estimation range. change. Further, the estimation range setting unit 25 is changed so as to narrow the estimation range when the movement direction related to the current operation and the movement direction related to the previous operation are different. More specifically, the estimation range setting unit 25 sets the value of the current parameter to one end value of the estimation range, or sets the other end value of the estimation range according to the amount of movement from one end value. The estimated range is set by setting a value separated by a predetermined distance set in the above.

The parameter moving unit 26 moves the parameters according to the new moving operation according to the moving amount set by the moving amount setting unit 24.

<Processing flow>
Next, the flow of processing executed by the information processing apparatus 1 according to the present embodiment will be described. The specific contents and processing order of the processing described below are examples for carrying out the present disclosure. The specific processing content and processing order may be appropriately selected according to the embodiment of the present disclosure.

FIG. 4 is a flowchart showing an outline of the flow of the parameter setting process according to the present embodiment. The process shown in this flowchart is executed every time a new movement operation input is received by the reception unit 22. It should be noted that a continuous user operation such as a long press of a button may be divided into predetermined time units or the like and treated as if a new movement operation is continuously and repeatedly input. ..

In step S1, it is determined whether or not there is a wrapping in the parameter moving direction. The direction determination unit 23 includes the movement direction of the parameter related to the newly input movement operation (current operation) and the movement related to the previously input movement operation (previous operation) held in the RAM 13 as the operation history. By comparing the directions, it is determined whether or not the moving direction related to the current operation and the moving direction related to the previous operation are different directions. By making such a determination, the direction determination unit 23 detects the wrapping of the operation direction (direction of parameter movement) by the user, and when the wrapping is detected, the current parameter passes the target value by the previous operation. It is estimated that it was. When the return in the parameter moving direction is detected, the process proceeds to step S2. On the other hand, if no wrapping is detected, the process proceeds to step S4.

However, if the previous operation and the current operation are separated from each other by a predetermined time or more, a new parameter adjustment with an intention (target value) different from that of the previous operation is performed instead of passing the target value. Since it may have been started, it may not be detected as a wrap. The variation including the time determination will be described later using the second embodiment.

In steps S2 and S3, the amount of movement is reduced and the estimated range is narrowed. When the return of the parameter movement direction is detected in step S1, the movement amount setting unit 24 reduces the parameter movement amount in one operation (step S2), and the estimation range setting unit 25 sets the parameter target by the user. The estimation range in which the value is estimated to be included is changed to be narrowed (step S3). After that, the process proceeds to step S7.

Here, as a specific method for reducing the movement amount, as will be described later in the second embodiment, for example, a method of dividing the current movement amount by a constant to reduce the movement amount according to a constant ratio is used. May be adopted. However, the means adopted for reducing the amount of movement is not limited to the examples disclosed in the present embodiment. For example, the movement amount may be updated to a value calculated using a function of the current parameter and the movement amount, such as "current movement amount * (current parameter / maximum value of the parameter) / coefficient". Further, a lower limit may be set for the movement amount.

Further, other variations may be adopted for changing the movement amount. For example, the execution of the process of reducing the movement amount may be limited only when the return within the estimated range is detected.

Further, as a specific method for narrowing the estimation range, as will be described later in the second embodiment, for example, the value of the parameter (that is, the current parameter) at the time when the wrapping occurs is set as the estimation range. A method in which one fraction is used and the value calculated using the current parameter and the function of the movement amount is used as the other fraction of the estimation range (for example, the offset calculated using the "movement amount * coefficient" is currently used. A method in which the value moved in the moving direction from the parameter of the above is used as the fractional value of the estimation range) or the like may be adopted.

However, the means adopted for narrowing the estimation range is not limited to the examples disclosed in the present embodiment. For example, the other fraction of the above estimation range is a value calculated using other functions such as "current parameter + movement direction x current movement amount x (current parameter / maximum value of parameter)". It may be updated.

In step S4, the relationship between the operation and the estimated range is determined. The estimation range setting unit 25 determines whether or not the current parameter or the parameter after movement by the current operation is outside the estimation range. By making such a determination, the estimation range setting unit 25 determines whether or not the operation intention by the user is intended to move the parameter significantly. If it is determined that the current parameter or the parameter after the movement by the current operation is out of the estimation range, the process proceeds to step S5. On the other hand, if it is determined that the current parameter or the parameter after the movement by the current operation is not outside the estimated range (within the estimated range), the process proceeds to step S7.

In steps S5 and S6, the amount of movement is increased and the estimated range is expanded. If the return of the parameter movement direction is not detected in step S1 and it is determined in step S4 that the current parameter or the parameter after movement by the current operation is out of the estimation range, the movement amount setting unit 24 performs once. The movement amount of the parameter in the operation of (step S5) is increased (step S5), and the estimation range setting unit 25 is changed so as to expand the estimation range estimated to include the target value of the parameter by the user (step S6). After that, the process proceeds to step S7.

Here, as a specific method for increasing the amount of movement, as will be described later in the second embodiment, for example, a method of multiplying the current amount of movement by a constant to increase the amount according to a certain ratio is adopted. May be done. However, the means adopted for increasing the amount of movement is not limited to the examples disclosed in the present embodiment. For example, the movement amount may be updated to a value calculated using a function of the current parameter and the movement amount, such as "current movement amount * (current parameter / maximum value of the parameter) / coefficient". Further, an upper limit may be set for the movement amount.

Further, as a specific method for expanding the estimation range, as will be described later in the second embodiment, for example, the value of the parameter (that is, the current parameter) at the time when the wrapping occurs is set as the estimation range. The method of using the fraction value or the method of using the value calculated using the function of the current parameter and the movement amount as the fraction value of the estimation range (for example, the offset calculated using the "movement amount * coefficient" is the current offset value. A method in which the value moved in the moving direction from the parameter is used as the fractional value of the estimation range) or the like may be adopted.

In step S7, the parameters are updated. The parameter moving unit 26 moves the current parameter by the set movement amount (movement amount after the change when changed in step S2 or step S5) in the movement direction related to the current operation. The parameter is moved according to a new movement operation. When moving the parameter, the parameter after the movement may be adjusted so as not to fall below the possible minimum value of the parameter or exceed the maximum value. After that, the process proceeds to step S8.

In step S8, the operation history is updated. The data holding unit 21 can use data such as the movement direction, the parameter after movement, the movement amount, and the operation interval related to the current operation as the data related to the previous operation when this flowchart is executed next time. Update the operation history. After that, the process shown in this flowchart ends.

[Second Embodiment]
Next, the second embodiment will be described. In the second embodiment, items that overlap the contents described in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

<System configuration>
The hardware configurations of the information processing device 1, the buttons 2a, 2b, and the parameter utilization device 3 according to the present embodiment are substantially the same as those of the first embodiment described with reference to FIG. 1, and thus the description thereof will be omitted. To do. In the present embodiment, in order to acquire the operation time, a clock for acquiring the reception time of the user operation is further provided (not shown).

FIG. 5 is a diagram showing an outline of the functional configuration of the information processing device 1 according to the present embodiment. The information processing device 1 first reads the program recorded in the storage device 14 into the RAM 13 and executes it by the CPU 11 to control each hardware provided in the image data processing server 1. In addition to the data holding unit 21, the receiving unit 22, the direction determination unit 23, the movement amount setting unit 24, the estimation range setting unit 25, and the parameter movement unit 26 described in the embodiment, the time acquisition unit 27 and the wait-and-see determination are further performed. It functions as a device including a unit 28 and an excess determination unit 29. In the present embodiment, each function included in the information processing device 1 is executed by the CPU 11 which is a general-purpose processor, but a part or all of these functions may be executed by one or a plurality of dedicated processors. ..

The time acquisition unit 27 acquires the time when the parameter movement operation is input.

The wait-and-see determination unit 28 determines whether or not the time from the input time of the previous operation to the input time of the current operation is within a predetermined time range to determine whether or not the user is waiting. To judge. For example, in the present embodiment, the wait-and-see determination unit 28 determines that the time from the input time of the previous operation to the input time of the current operation is predetermined with respect to the time from the input time of the previous operation to the input time of the previous time. If it is within the range of the ratio, it is determined that the user is waiting.

When the excess determination unit 29 moves the parameter according to the currently set movement amount before the parameter is moved by the parameter moving unit 26, whether or not the moved parameter is less than the minimum value of the parameter, and whether or not the parameter is moved. , Determine whether the parameter after movement exceeds the maximum value of the parameter.

Further, in the present embodiment, in addition to the processing described in the first embodiment, the movement amount setting unit 24 is currently in operation when it is determined by the wait-and-see determination unit 28 that the user is in the wait-and-see manner. The movement amount of the corresponding parameter is reduced, and when the wait-and-see determination unit 28 determines that the user is not in the wait-and-see manner, the movement amount of the parameter according to the current operation is increased. At this time, the estimation range setting unit 25 may reset the estimation range to a range that matches the current parameter and the movement amount after the increase in accordance with the increase in the movement amount.

Further, when the excess determination unit 29 determines that the parameter after movement is less than the minimum value of the parameter, the movement amount setting unit 24 determines the movement amount of the parameter according to the current operation, and the parameter after movement corresponds to the parameter after movement. When the movement amount is reduced to a movement amount not less than the minimum value of the parameter and the excess determination unit 29 determines that the parameter after movement exceeds the maximum value of the parameter, the movement amount of the parameter according to the current operation is changed after movement. The parameter of is reduced to the amount of movement that does not exceed the maximum value of the parameter.

FIG. 6 is a diagram showing a data structure used to show an operation content in the present embodiment. The data structure indicating the operation content includes direction data indicating the direction in which the parameter is moved according to the operation, time data indicating the time when the operation was performed, and an operation interval from the previous operation to the operation being performed. Interval data indicating (time) and value data indicating the value of the parameter moved by the operation are included. Further, as the substance of the data indicating the operation content, at least the current operation data for storing the operation content currently being processed and the previous operation data for storing the previous operation content are prepared. Hereinafter, the direction data, time data, interval data, and value data related to the current operation are referred to as "current operation.direction", "current operation.time", "current operation.interval", and "current operation.value". The direction data, time data, interval data, and value data related to the operation are expressed as "previous operation. Direction", "previous operation. Time", "previous operation. Interval", and "previous operation. Value".

<Processing flow>
Next, the flow of processing executed by the information processing apparatus 1 according to the present embodiment will be described. The specific contents and processing order of the processing described below are examples for carrying out the present disclosure. The specific processing content and processing order may be appropriately selected according to the embodiment of the present disclosure.

7 and 8 are flowcharts showing an outline of the flow of the parameter setting process according to the present embodiment. The process shown in this flowchart is executed every time the information processing device 1 receives an input of a new movement operation. It should be noted that a continuous user operation such as a long press of a button may be divided into predetermined time units or the like and treated as if a new movement operation is continuously and repeatedly input. ..

In step S101, the parameter movement direction determination process is executed. The direction determination unit 23 determines the movement direction of the parameter related to the current operation, which is a newly input movement operation, and determines the current operation data including the movement direction, and the relationship between the upper end value / lower end value indicating the estimated range and the movement direction. To set. The details of the movement direction determination process will be described later with reference to FIG. When the moving direction of the parameter is determined, the process proceeds to step S102.

FIG. 9 is a flowchart showing an outline of the flow of the movement direction determination process according to the present embodiment. This flowchart describes the details of the movement direction determination process shown in step S101 of FIG.

In steps S201 and S202, input waiting by user operation and type determination of input operation are performed. When any of the buttons 2a and 2b is operated by the user, the reception unit 22 receives the input signal corresponding to the operated button (step S201). When the input signal is received, the direction determination unit 23 determines whether the received input signal is an input signal indicating that the button 2a (here, the button instructing the increase of the parameter) has been operated. , Or, it is determined whether the button 2b (here, it is a button instructing the decrease of the parameter) is an input signal indicating that the operation has been performed (step S202). If the result of the determination is that the input signal indicates an increase in the parameters, the process proceeds to step S203. On the other hand, if the input signal indicates a decrease in the parameters, the process proceeds to step S204.

In step S203, the moving direction and the relationship between the upper end value / lower end value indicating the estimated range and the moving direction are set. When the input signal indicates an increase in the parameters, the direction determination unit 23 sets a value "+1" indicating the increasing direction in the variable indicating the moving direction. Further, the data holding unit 21 reduces the lower end value among the upper end value and the lower end value indicating the currently set estimated range in the direction opposite to the moving direction (here, the increasing direction) related to the current operation (here, the decreasing direction). The upper end value is set to be referred to as the offset value Rb in the direction), and the upper end value is set to be referred to as the reverse end value Rf in the movement direction (here, the increasing direction) related to the current operation. After that, the process proceeds to step S205.

In step S204, the moving direction and the relationship between the upper end value / lower end value indicating the estimated range and the moving direction are set. When the input signal indicates the decrease of the parameter, the direction determination unit 23 sets a value "-1" indicating the decrease direction in the variable indicating the moving direction. Further, the data holding unit 21 increases the upper end value among the upper end value and the lower end value indicating the currently set estimated range in the direction opposite to the moving direction (here, the decreasing direction) related to the current operation (here, increasing). The lower end value is set to be referred to as the lower end value Rb in the direction), and the lower end value is set to be referred to as the reverse end value Rf in the moving direction (here, the decreasing direction) related to the current operation. After that, the process proceeds to step S205.

In step S205, the current operation data is set. The data holding unit 21 sets the moving direction (+1 or -1) set in step S203 or step S204 as the moving direction (current operation. Direction) in the current operation data indicating the content of the current operation. , Of the current operation data, the current time acquired from the time acquisition unit 27 is set in the operation time (current operation.time). After that, the process shown in this flowchart is completed, and the process proceeds to step S102 in FIG.

In step S102, the wait-and-see determination process is executed. The wait-and-see determination unit 28 determines whether or not the user is currently watching, and sets a wait-and-see flag (wait-and-see determination result) based on the operation interval. The details of the wait-and-see determination process will be described later with reference to FIG. When the wait-and-see determination is completed, the process proceeds to step S103.

FIG. 10 is a flowchart showing an outline of the flow of the wait-and-see determination process according to the present embodiment. This flowchart describes the details of the wait-and-see determination process shown in step S102 of FIG.

In step S301 and step S302, the operation interval (time) from the previous operation to the current operation and the change rate of the operation interval are calculated. The wait-and-see determination unit 28 calculates the operation interval (current operation. Time-previous operation. Time) from the previous operation to the current operation, and among the current operation data indicating the contents of the current operation, the operation interval (current operation. Interval). ) (Step S301). Then, the wait-and-see determination unit 28 calculates an interval ratio (= current operation. Interval / previous operation. Interval) indicating the ratio of the operation interval from the previous operation to the current operation to the operation interval from the previous operation to the previous operation. In, the change rate of the operation interval is acquired (step S302). After that, the process proceeds to step S303.

In step S303, it is determined whether or not the user is watching. The wait-and-see determination unit 28 is watching the user when the interval ratio (change rate of the operation interval) calculated in step S302 is equal to or more than the predetermined wait-and-see interval ratio and less than or equal to the predetermined satisfaction interval ratio. Is determined, and the wait-and-see flag indicating that the user is watching is set to "enabled". On the other hand, if it is determined that the user is not in the wait-and-see, the wait-and-see flag is set to "invalid".

The interval ratio, which indicates the ratio of the operation interval from the previous operation to the current operation to the operation interval from the previous operation to the previous operation, is a relatively small value when the user is performing continuous operations at relatively equal intervals ( (Around 1), which is a relatively large value when the user is operating while watching whether the currently set parameters are acceptable, and the user is satisfied with the currently set parameters to perform the operation. If the operation is restarted after stopping, the value becomes even larger.

Therefore, in the present embodiment, when the interval ratio calculated in step S302 is less than the wait-and-see interval ratio (for example, 4), it is estimated that the user is continuously performing operations at relatively equal intervals. However, if the interval ratio is greater than the satisfaction interval ratio (eg, 32), it is estimated that the user is satisfied with the currently set parameters, stops the operation, and then resumes the operation, and the interval ratio. If the wait-and-see interval ratio (for example, 4) or more and the satisfaction interval ratio (for example, 32) or less, it is estimated that the user is performing the operation while watching whether the currently set parameters are acceptable. And said. When the wait-and-see flag is set, the process shown in this flowchart ends, and the process proceeds to step S103 in FIG.

In step S103, it is determined whether or not there is a wrapping in the parameter moving direction. The direction determination unit 23 compares the moving direction of the parameter related to the current operation (current operation. Direction) with the moving direction related to the previous operation (previous operation. Direction) which is the movement operation input one time before. By determining whether or not the moving direction related to the current operation and the moving direction related to the previous operation are different, the return of the parameter moving direction is detected. When the return in the parameter moving direction is detected, the process proceeds to step S104. On the other hand, if no wrapping is detected, the process proceeds to step S110.

In step S104, the amount of movement of the parameter is reduced. When the return in the parameter moving direction is detected in step S103, the moving amount setting unit 24 reduces the moving amount of the parameter in one operation. More specifically, in the present embodiment, the movement amount setting unit 24 has a value obtained by dividing the current movement amount by a predetermined constant (2 in the present embodiment) and a preset minimum movement. The larger value of the amount (for example, 1) is set as the new movement amount. By doing so, it is possible to control the movement amount so that the movement amount does not fall below the predetermined minimum movement amount while increasing or decreasing the movement amount according to a predetermined magnification (2 in the present embodiment). After that, the process proceeds to step S105.

In the present embodiment, when the wrapping in the parameter moving direction is detected, the moving amount of the parameter is uniformly reduced. However, instead of such a configuration, when the wrapping in the parameter moving direction is detected. Further, it may be determined whether or not the current parameter (parameter after movement by the previous operation) is within the estimation range, and the movement amount of the parameter may be reduced only when it is within the estimation range.

In step S105, the estimation range is narrowed. When the return in the parameter moving direction is detected in step S103, the estimation range setting unit 25 changes so as to narrow the estimation range estimated to include the target value of the parameter by the user. More specifically, in the present embodiment, the estimation range setting unit 25 sets the last value Rb, which is opposite to the moving direction related to the current operation, to the last value Rb, Rf, which defines the estimation range. Set the parameters (that is, the previous operation. Value) after the movement by the operation. The relationship between the two fractional values Rb and Rf and the upper end value and the lower end value of the estimation range is as described above in the description of the movement direction determination process.

By doing so, when the moving direction is changed to the increasing direction, the lower end value of the estimation range is set to the value of the folding point, and the estimation range is narrowed down. On the other hand, when the moving direction is changed to the decreasing direction, the upper end value of the estimation range is set to the value of the turnaround point, and the estimation range is narrowed down. After that, the process proceeds to step S106.

In steps S106 and S107, when the estimated range is too wide with respect to the movement amount, the estimated range is further narrowed. The estimation range setting unit 25 determines whether or not the width of the estimation range is a predetermined ratio (4 in this embodiment) or more of the movement amount, so that the estimation range is too wide with respect to the movement amount (in this embodiment). In the present embodiment, it is determined whether or not the number is four times or more (step S106). Specifically, the estimation range setting unit 25 compares the absolute value of "off-value Rb-reverse end value Rf" with the "predetermined ratio * movement amount", and the absolute value of "off-value Rb-reverse end value Rf". When the value is "predetermined ratio * movement amount" or more, it is determined whether or not the estimated range is too wide for the movement amount. If it is determined that the estimated range is not too wide (less than 4 times) with respect to the movement amount, the estimated range is not further changed, and the process proceeds to step S108.

On the other hand, when it is determined that the estimated range is too wide (four times or more) with respect to the movement amount, the estimation range setting unit 25 relates to the current operation among the two fractional values Rb and Rf that define the estimated range. By changing the reverse end value Rf in the moving direction, the estimation range is further narrowed (step S107). More specifically, the estimation range setting unit 25 moves a value (= end) obtained by multiplying the movement amount by a predetermined ratio (4 in this embodiment) from the current end value Rb in the movement direction related to the current operation. By setting the reverse end value Rf in the value Rb + current operation. Direction * movement amount * predetermined ratio), the width of the estimated range is changed to an appropriate width (in this embodiment, four times the movement amount). To do. After that, the process proceeds to step S108.

In step S108 and step S109, the movement amount is reduced when the parameter is out of the estimation range during the wait-and-see or after the movement. The wait-and-see determination unit 28 determines whether or not the wait-and-see flag (wait-and-see determination result) is set to valid (a value indicating that the user is watching), and further, the currently set movement. If the parameter is moved by the quantity, it is determined whether or not the parameter is out of the estimated range (outside the reverse end value Rf) (step S108). As a result of the determination, when it is determined that the user is waiting or the parameter is out of the estimation range after the movement, the movement amount setting unit 24 further reduces the movement amount (step S109). Since the specific processing content for reducing the movement amount is substantially the same as the processing content described in step S104, the description thereof will be omitted. After that, the process proceeds to step S122.

In steps S110 to S112, the relationship between the current parameter and the estimated range and the setting content of the wait-and-see flag are determined. The estimation range setting unit 25 determines whether or not the current parameter is a value inside the estimation range (excluding the edge value Rb or the reverse end value Rf) (step S110). The estimation range setting unit 25 calculates a value obtained by moving the current parameter by the amount of movement currently set in the direction related to the current operation, and the calculated parameter after the movement is inside the estimation range (fractional value Rb or It is determined whether or not the value is (excluding the inverse value Rf). Further, the wait-and-see determination unit 28 determines whether or not the result of the wait-and-see determination (wait-and-see flag) performed in step S102 is set to indicate that the user is currently watching. Step S111 and step S112).

If, as a result of the determinations shown in steps S110 to S112, it is determined that the current parameter is inside the estimation range and the user is watching, the process proceeds to step S113. If it is determined that the current parameter is equal to or outside the edge of the estimation range (fractional value Rb or reverse endpoint value Rf) and the user is on the lookout, the process proceeds to step S115. If it is determined that the current parameter is equal to or outside the edge of the estimation range (fractional value Rb or reverse endpoint value Rf) and the user is not on the lookout, the process proceeds to step S118. If it is determined that the current parameter is inside the estimated range and the user is not on the lookout, the process proceeds to step S120.

In step S113 and step S114, the estimation range is changed and the movement amount of the parameter is reduced. Here, in the determination in step S110, it is determined that the current parameter is inside the estimation range, and the current parameter is close to the opposite end value Rf. Further, in the determination in step S111, it is determined that the user is watching, and it is presumed that the user wants to make fine adjustments.

Therefore, the estimation range setting unit 25 sets the parameter (that is, the parameter after the movement by the previous operation) to the terminal value Rb in the direction opposite to the movement direction related to the current operation among the two edge values Rb and Rf that define the estimation range. , Last operation. Value) is set (step S113). When the moving direction is the increasing direction, the lower end value of the estimation range is set to the value of the folding point. On the other hand, when the moving direction is the decreasing direction, the upper end value of the estimation range is set to the value of the folding point.

When the fractional value Rb is updated, the movement amount setting unit 24 reduces the movement amount until the reverse end value Rf becomes farther than the predetermined ratio * movement amount from the current parameter or becomes the lower limit of the movement amount. Is repeated (step S114). Since the specific processing content for reducing the movement amount is substantially the same as the processing content described in step S104, the description thereof will be omitted. After that, the process proceeds to step S120.

From step S115 to step S117, the estimation range is changed and the amount of movement of the parameter is reduced. Here, in the determination in step S110, it is determined that the current parameter is the same as or outside the edge (fractional value Rb or reverse endpoint value Rf) of the estimation range, and the current parameter is the inverse endpoint value Rf. Same as or has passed. Further, in the determination in step S112, it is determined that the user is watching, and it is presumed that the user wants to make fine adjustments.

Therefore, the movement amount setting unit 24 executes a process of reducing the movement amount (step S115). Since the specific processing content for reducing the movement amount is substantially the same as the processing content described in step S104, the description thereof will be omitted.

Further, the estimation range setting unit 25 sets the parameter (that is, that is, the parameter after the movement by the previous operation) to the terminal value Rb in the direction opposite to the movement direction related to the current operation among the two edge values Rb and Rf that define the estimation range. The previous operation. Value) is set (step S116). When the moving direction is the increasing direction, the lower end value of the estimation range is set to the value of the folding point. On the other hand, when the moving direction is the decreasing direction, the upper end value of the estimation range is set to the value of the folding point.

Further, the estimation range setting unit 25 further narrows the estimation range by changing the reverse end value Rf in the moving direction related to the current operation among the two edge values Rb and Rf that define the estimation range (step S117). ). Since the specific processing content for changing the inverse value Rf is substantially the same as the processing content described in step S107, the description thereof will be omitted. After that, the process proceeds to step S120.

In step S118 and step S119, the estimation range is changed and the movement amount of the parameter is increased. Here, in the determination in step S110, it is determined that the current parameter is the same as or outside the edge (fractional value Rb or reverse endpoint value Rf) of the estimation range, and the current parameter is the inverse endpoint value Rf. Same as or has passed. Further, in the determination in step S112, it is determined that the user is not in the wait-and-see manner, and the user repeats the operation in a short time in hopes of reaching a target value outside the estimated range, or is longer than the previous operation. It is presumed that you want to move the parameter to a different value again over time.

Therefore, the estimation range setting unit 25 sets the opposite end value Rf in the moving direction related to the current operation among the two edge values Rb and Rf that define the estimation range to the parameter after the movement by the previous operation (that is, the previous time). The operation (value) is set (step S118), and the movement amount setting unit 24 increases the movement amount of the parameter in one operation (step S119). More specifically, in the present embodiment, the movement amount setting unit 24 has a value obtained by multiplying the current movement amount by a predetermined constant (2 in the present embodiment) and a preset maximum movement. The smaller value of the amount (for example, 16) is set as the new movement amount. By doing so, it is possible to control the movement amount so that the movement amount does not exceed the predetermined maximum movement amount while increasing or decreasing the movement amount according to a predetermined magnification (2 in the present embodiment). After that, the process proceeds to step S120.

When changing the estimation range in step S118, the estimation range setting unit 25 changes the edge value Rb in the opposite direction of the moving direction related to the current operation among the two edge values Rb and Rf that define the estimation range. You may. Since the specific processing content when changing the fractional value Rb is substantially the same as the processing content described in step S107, the description thereof will be omitted.

In steps S120 and S121, the amount of movement of the parameter is reduced when the parameter is likely to exceed the minimum / maximum value. If the parameter is moved by the currently set movement amount, the excess determination unit 29 determines whether the parameter is below the minimum value (0 in the present embodiment) or the maximum value (127 in the present embodiment). It is determined whether or not it exceeds (step S120). As a result of the determination, when it is determined that the parameter exceeds the minimum value / maximum value after the movement, the movement amount setting unit 24 further reduces the movement amount (step S121). Since the specific processing content for reducing the movement amount is substantially the same as the processing content described in step S104, the description thereof will be omitted. After that, the process proceeds to step S122.

In step S122, the parameters are updated. The parameter moving unit 26 moves the current value of the parameter in the moving direction determined in step S101 by the amount of movement set in the processes up to step S122. More specifically, for example, when the moving direction is an increase or decrease of the parameter and the moving direction takes a value of "+1 (increase)" or "-1 (decrease)", the parameter moving unit 26 is a parameter of the parameter. The parameter is updated by adding "movement direction * movement amount" to the current value. However, it is assumed that the parameter does not fall below the preset minimum value (for example, 0) and does not exceed the preset maximum value (for example, 127). Further, the data holding unit 21 sets the updated parameter to a value (current operation. Value) in the current operation data. After that, the process proceeds to step S123.

In step S123, the operation history is updated. The data holding unit 21 converts the contents of the current operation data (“current operation. Direction”, “current operation. Time”, “current operation. Interval”, and “current operation. Value”) into the previous operation data (“previous operation. Direction”). , "Last operation. Time", "Last operation. Interval" and "Last operation. Value") to update the previous operation data. By doing so, when the process shown in this flowchart is executed next time, the operation content of the previous operation can be grasped by referring to the previous operation data. The data holding unit 21 may accumulate the operation history over a predetermined period. After that, the process shown in this flowchart ends.

<Example>
FIG. 11 is a diagram A showing how the current value, the amount of movement, and the estimated range of the parameters change when the parameters are actually adjusted using the information processing device 1 according to the present embodiment. According to this figure, in the operation process of adjusting the parameter from 64 to 87, which is coded (1), the amount of movement is reduced each time the parameter is folded back within the estimated range, and the estimated range is narrowed down and finely adjusted. You can see that.

It can be seen that in the operation process of adjusting the parameter from 87 to 60, which is indicated by the reference numeral (2), the movement amount deviates from the estimated range in the fourth operation and the movement amount is doubled. Further, after the operation direction is turned back, it can be seen that the movement amount is rapidly reduced, the estimated range is narrowed, and the target value is converged, as in the case of (1).

In the process of adjusting the parameter from 60 to 64, coded (3), the target value was reached before the estimation range was narrowed, and the parameter, coded (4), was coded from 64 to 62. In the operation process of adjusting to, the movement is in the same direction as the previous operation within the estimated range, but since the state was observed for a while with the parameter set to 64, it can be seen that the movement amount was reduced.

FIG. 12 is a diagram B showing how the current value, the amount of movement, and the estimated range of the parameters change when the parameters are actually adjusted using the information processing device 1 according to the present embodiment. According to this figure, even if the target value of the parameter to be moved is far away, the operation intention by the user is appropriately reflected and the movement amount is adjusted, and the target value is reached with a small number of operations. You can see that. Further, according to this figure, it can be seen that the movement amount is forcibly reduced when the parameter approaches the minimum value.

<Effect>
According to the embodiment described above, the user receives an instruction for fine adjustment / coarse adjustment by guessing the context of the user operation (the user's operation intention determined from the operation history) and changing the movement amount of the parameter. It is possible to automatically switch between fine adjustment and coarse adjustment according to the user's operation intention, and it is possible to reach a wide range of target values with a smaller amount of operation.
