Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<1. First Embodiment>
<1-1. Operation device configuration>
1 and 2 are diagrams showing an outline of the operating device 10 according to the present embodiment. In the present embodiment, the operating device 10 mounted on a vehicle such as an automobile will be described as an example. FIG. 1 is a diagram showing a state of the vehicle interior in which the operating device 10 is mounted. FIG. 2 is a diagram showing a schematic configuration of the operating device 10.

As shown in FIG. 1, the operating device 10 is an electronic device provided at a position visible to the user, such as a center console of a vehicle, and having at least a display unit and a touch sensor. Further, when the user operates the operating device 10, the touch sensor vibrates to give the user a tactile sensation. In particular, when the user's operation amount reaches a predetermined amount, a predetermined tactile sensation is given, and even when the user operates without looking at the operation device 10, the operation amount or the like is given to the user. The operation content can be fed back.

As shown in FIG. 2, the operation device 10 includes a control unit 11, a storage unit 12, a vehicle position information acquisition unit 13, a display unit 14, a touch sensor 15, a touch sensor controller 16, and a vibration element 17.

The control unit 11 is a computer including a navigation unit 11a, a display control unit 11b, an operation determination unit 11c, and a vibration control unit 11d, and includes a CPU, RAM, and ROM (not shown). The control unit 11 is connected to a storage unit 12 or the like included in the operation device 10, transmits / receives information based on the program 12a stored in the storage unit 12, and controls the entire operation device 10. When the CPU executes arithmetic processing according to the program 12a stored in the storage unit 12, various functions of the control unit 11 including the navigation unit 11a and the display control unit 11b are realized.

The navigation unit 11a searches for a route from the current position of the vehicle to the destination and guides the vehicle. The navigation unit 11a acquires the current vehicle position information acquired by the vehicle position information acquisition unit 13 and the map information 12c stored in the storage unit 12. Then, the navigation unit 11a creates a navigation image in which the current position of the vehicle is displayed on the surrounding map based on the vehicle position information and the map information. When the destination is set, the navigation unit 11a searches for the route to the destination and creates a navigation image in which the route to the destination is highlighted in the navigation image.

The display control unit 11b controls the display unit 14 to display the navigation image created by the navigation unit 11a. The display control unit 11b also controls the display unit 14 to display an adjustment image for changing the adjustment value of the air conditioner, audio, or the like.

The operation determination unit 11c determines the operation content of the user. Specifically, the operation content of the user is determined based on the position information (hereinafter referred to as "operation position information") in which the user operates the touch sensor 15. Further, the operation determination unit 11c derives the operation amount of the user based on this position information.

The vibration control unit 11d controls the vibration of the touch sensor 15 according to the operation content of the user determined by the operation determination unit 11c. Specifically, the vibration control unit 11d controls the vibration element 17 to vibrate according to the amount of change in the user's operation. For example, the vibration control unit 11d vibrates the vibrating element 17 every time the amount of operation by the user becomes a constant amount to vibrate the touch sensor 15. As a result, the user can obtain a tactile sensation every time a certain amount of operation is performed, so that the user can recognize how much the operation has been performed.

The storage unit 12 stores the program 12a, the vehicle position information 12b, and the map information 12c. The storage unit 12 in the present embodiment is a non-volatile semiconductor memory that can electrically read and write data and does not erase the data even when the power supply is cut off. As the storage unit 12, for example, an EEPROM (Electrical Erasable Programmable Read-Only memory) or a flash memory can be used. However, other storage media may be used, and a hard disk drive including a magnetic disk may be used.

The program 12a is so-called system software that is read by the control unit 11 and executed by the control unit 11 to control the operation device 10. The vehicle position information 12b is information indicating the position of the vehicle acquired by the vehicle position information acquisition unit 13. Further, the map information 12c is national or certain wide area road information and traffic information.

The vehicle position information acquisition unit 13 acquires vehicle position information as information indicating the current position of the vehicle. As the vehicle position information acquisition unit 13, for example, GPS (Global positioning system) can be used. Further, the vehicle position information is information including longitude information and latitude information.

The display unit 14 is a display device for displaying a navigation image or an adjusted image, such as a liquid crystal display or an organic EL (Electro Luminescence) display.

The touch sensor 15 is a flat plate-shaped sensor in which the user performs an input operation. The touch sensor 15 is provided on the display surface of the display unit 14 (on the surface on the user side). That is, the display unit 14 and the touch sensor 15 provided on the display surface thereof function as a so-called touch panel.

On the display surface of the display unit 14, a command button for receiving a user's instruction is appropriately displayed. The user can give an instruction associated with the command button to the operation device 10 by touching the area in the operation surface of the touch sensor 15 corresponding to the area of the command button with a finger.

Further, the touch sensor 15 is arranged so that the vibrating element 17 is in contact with the touch sensor 15, and the vibrating element 17 vibrates according to the operation of the user's touch sensor 15. When the vibrating element 17 vibrates, the operation surface of the touch sensor 15 also vibrates, giving the user a tactile sensation.

As a method of the touch sensor 15, for example, a capacitance method of detecting a position by capturing a change in capacitance is adopted. The user can perform not only an operation of touching the operation surface of the touch sensor 15 at one point but also a multi-touch operation of touching at a plurality of points.

The touch sensor controller 16 is, for example, a hardware circuit and controls the operation of the touch sensor 15. The touch sensor controller 16 includes a touch detection unit 16a that detects a position touched by the user on the operation surface of the touch sensor 15 based on the signal generated by the touch sensor 15.

The touch detection unit 16a detects a position touched by the user (for example, XY coordinates) by, for example, a mutual capacitance method for measuring a change in capacitance between two electrodes of a driving electrode and a receiving electrode. The touch detection unit 16a detects whether or not the user has touched based on the fact that the electric charge received by the receiving electrode is reduced by blocking the electric field with the user's finger.

The touch detection unit 16a can determine whether the user touches the operation surface of the touch sensor 15 at one point or a plurality of points. Then, the touch detection unit 16a detects the position of the one point when the user touches the operation surface of the touch sensor 15 at one point, and detects the position of each of the plurality of points when the user touches the operation surface of the touch sensor 15 at a plurality of points. To do.

The vibrating element 17 is a member that vibrates the operation surface of the touch sensor 15. More specifically, as shown in FIG. 3, a plurality of vibrating elements 17 are arranged around the operation surface of the touch sensor 15. Then, the vibrating element 17 itself vibrates to vibrate the operation surface of the touch sensor 15. The vibrating element 17 vibrates under the control of the vibration control unit 11d. As the vibrating element 17, for example, a piezoelectric element such as a piezo element can be used. Further, in the present embodiment, the vibrating elements 17 are arranged side by side on two opposite sides of the touch sensor 15, but the present invention is not limited to this, and an arbitrary number of vibrating elements 17 are arranged on an arbitrary side. do it.

<1-2. User operation and tactile activation>
Next, a process when the user operates the operating device 10 and a process for activating the tactile sensation at that time will be described. In the present embodiment, a process of adjusting the set temperature of the air conditioner and a process of activating the tactile sensation during the adjusting operation will be described as an example. In the present invention, "the tactile sensation is activated" means that the touch sensor 15 is vibrated to give the user a tactile sensation. Further, in the present invention, the "adjustment value" indicates a set value (that is, a value to be adjusted) to be changed in the processing of the adjustment operation. The adjustment value is, for example, the value of the set temperature of the air conditioner.

FIG. 4 is a diagram illustrating a user operating the touch sensor 15 of the operating device 10. As shown in FIG. 4, the display unit 14 of the operation device 10 displays the setting state of the air conditioner in the lower portion thereof. Specifically, a set state such as a set temperature of 23.0 ° C. and an air volume of 4 is displayed.

For example, as shown in FIG. 4, when the user touches the portion displaying the set temperature of the display unit 14 (the portion of 23.0 displayed at the lower left of the display unit 14), as shown in FIG. The adjustment image of the set temperature is displayed. The adjustment image shown in FIG. 5 has a circular operation area 14a for adjusting the set temperature and a circular display area 14b for displaying the adjustment value outside the operation area. In the example of FIG. 5, the operation area 14a displays the entire circular area, but the display area 14b displays a part of the circular area. In addition, the current set temperature of 23.0 is displayed in the upper center of the display area 14b, and the front and rear set temperatures of 22.0 and 24.0 are displayed on the left and right circumferences. There is.

When the user touches the operation area 14a and operates it in a circular shape along the operation area 14a, the adjustment value of the display area 14b is rotated and displayed accordingly. Specifically, as shown in FIG. 6, when the user operates on the operation area 14a in a circular motion, the value of the set temperature in the display area 14b rotates and moves according to the operation amount. For example, the user touches an arbitrary position in the operation area 14a and performs an operation of drawing an arc of about 120 ° (1/3 circumference) from that position. Then, the display area 14b rotates and moves according to the operation, and the adjustment value 23.0 displayed in the upper center changes to 22.0.

As described above, in the present embodiment, when an operation such as adjustment of the set temperature is performed, if an arbitrary position of the operation area 14a is touched, that position becomes the current adjustment value, and the operation amount from the position becomes the current adjustment value. The adjustment value can be changed. That is, when the position corresponding to each temperature is predetermined, it is necessary to touch the position corresponding to the current adjustment value for temperature adjustment, but in the present embodiment, in the operation area 14a. If so, no matter which position is touched, the first touched position will be the current adjustment value. Therefore, even in a situation where the user cannot stare at the display unit 14 of the operation device 10, if an arbitrary position of the operation area 14a can be touched, the adjustment value is changed according to the operation amount from that position. It becomes possible to do.

In the above description, an example in which the adjustment value changes by 1.0 ° C. when the user draws an arc of about 120 ° C. has been described, but the present invention is not limited to this. The correspondence between the user's operation amount and the change amount of the adjustment value is arbitrary and can be set appropriately. That is, the correspondence relationship may be determined in advance, and the display may be changed by the amount of change corresponding to the operation amount of the user.

Further, in the present embodiment, the tactile sensation is given every time the user's operation reaches a predetermined amount. Therefore, in the following, a method of generating a tactile sensation by vibrating the touch sensor 15 and an activation of the tactile sensation corresponding to the operation will be described.

In order to generate a tactile sensation, the vibration control unit 11d first vibrates the vibrating element 17 at high speed. This high-speed vibration is, for example, ultrasonic vibration. The surface of the touch sensor 15 can be ultrasonically vibrated by ultrasonically vibrating the vibrating element 17. By vibrating the vibrating elements 17 arranged on the two opposite sides as shown in FIG. 3, the entire surface of the touch sensor 15 can be vibrated substantially uniformly.

When the surface of the touch sensor 15 is operated with a finger while the surface of the touch sensor 15 is ultrasonically vibrated, a high-pressure air film is generated between the finger and the surface of the touch sensor 15 vibrating at high speed, and the frictional resistance is reduced. .. As a result, the user can obtain a smooth and smooth tactile sensation (hereinafter referred to as "smooth sensation") as compared with the non-vibrating state.

Further, when the vibration of the vibrating element 17 is stopped while the surface of the touch sensor 15 is ultrasonically vibrated, the ultrasonic vibration of the surface of the touch sensor 15 is also stopped. Then, the frictional resistance on the surface of the touch sensor 15 returns from the reduced state to the original state (non-vibrating state). That is, it changes from a low friction state to a high friction state. In this case, the tactile sensation changes from a slippery tactile sensation to a snagging tactile sensation. The user obtains a click feeling when changing from this slippery feeling to a feeling of being caught. This click feeling is referred to as "click feeling" below.

Further, when the surface of the touch sensor 15 is ultrasonically vibrated by changing the vibration intensity of the vibrating element 17, it is possible to vibrate the surface of the touch sensor 15 with a relatively large amplitude or a small amplitude. .. As a result, the surface of the touch sensor 15 can be brought into a state in which a high friction state and a low friction state are repeated. That is, the user alternately feels a smooth feeling and a click feeling as a tactile sensation, and in this case, an uneven tactile sensation or a rough tactile sensation (hereinafter referred to as “roughness”) can be obtained.

In addition, the degree of roughness can be changed by changing the magnitude of the strength of vibration or changing the cycle of changing the strength. As a result, it is possible to gradually realize a plurality of types of rough feelings such as a strong rough feeling, a weak rough feeling, and a sparse density feeling of the rough feeling.

In this way, the user can be given a tactile sensation by ultrasonically vibrating the vibrating element 17 and ultrasonically vibrating the surface of the touch sensor 15. Further, if the start and stop timings and strengths of ultrasonic vibrations are appropriately controlled, the frictional resistance of the surface can be changed, and by using this, it is possible to give various tactile sensations. ..

In this embodiment, a click feeling is given every time the user's operation reaches a predetermined amount. For example, every time the user draws an arc of 30 ° (1/12 lap) in the operation area 14a, a click feeling is given. In this case, when the user draws an arc of 120 °, a click feeling can be obtained four times every 30 °. That is, the user can recognize that the operation of 120 ° has been performed by obtaining the tactile sensation of four clicks even in the state of operating without looking at the display unit 14. That is, the user can recognize how much the operation has been performed.

Further, in the case of the operation example of adjusting the set temperature, for example, if the upper limit of the adjustment value is 32.0 ° C and the lower limit is 18.0 ° C, the upper limit value or the lower limit value may be exceeded depending on the operation amount of the user. In some cases. Therefore, when there is an operation exceeding the upper limit value or the lower limit value, the tactile sensation is activated when the upper limit value or the lower limit value is displayed. It is preferable that this tactile sensation is different from the tactile sensation given for each predetermined amount. By being given this tactile sensation, the user can recognize that the operation exceeds the upper limit value or the lower limit value.

In addition, when the user draws an arc, the tactile sensation given when drawing an arc in the forward rotation direction (clockwise) and the operation of drawing an arc in the reverse rotation direction (counterclockwise) are performed. It may be different from the tactile sensation given to. In this case, it is possible to recognize from the tactile sensation which direction the operation is being performed.

<1-3. Operation device processing>
Next, the processing of the operating device 10 will be described. FIG. 7 is a flowchart showing the processing of the operating device 10. The operation device 10 starts processing when the power is turned on and started. The operating device 10 is in a standby state until there is an operation by the user, and monitors whether or not there is a display instruction on the adjustment screen (step S10). Specifically, the operation device 10 monitors whether or not the user has instructed to display the adjustment screen by touching the area of the setting image displayed at the lower part of the display unit 14.

The operation device 10 acquires position information (for example, X coordinate and Y coordinate) when the user operates the touch sensor 15, determines the operation position and operation content of the user, and adjusts when a predetermined operation is performed. Judge that there was an instruction to display the screen. The predetermined operation is, for example, an upward flick operation. That is, the operating device 10 determines that the position touched by the user is the area of the set image based on the X coordinate and the Y coordinate when the user touches it, and upwards from the subsequent changes in the X coordinate and the Y coordinate. If it is determined that there has been a flick operation to, it is determined that there has been an instruction to display the adjustment screen.

Then, if there is no display instruction on the adjustment screen (No in step S10), the operating device 10 again monitors whether or not there is a display instruction on the adjustment screen. On the other hand, when there is an instruction to display the adjustment screen (Yes in step S10), the operating device 10 displays the adjustment screen (step S11). Specifically, the operation device 10 displays an adjustment screen related to the setting image touched by the user. That is, when the user touches the display image of the set temperature and flicks it up, the temperature setting adjustment screen is displayed.

Next, the operating device 10 determines whether or not there has been an operation on the operating area 14a (step S12). Also in this process, the operation device 10 acquires the position information (X coordinate and Y coordinate) when the user operates the touch sensor 15, determines the operation position and operation content of the user, and operates the operation area 14a. Determine if there was any.

When there is an operation on the operation area 14a (Yes in step S12), the operation device 10 derives the operation amount (step S13). That is, the operating device 10 derives the amount (distance) in which the user operates the operating area 14a. This is derived based on the amount of change in the position information (X coordinate and Y coordinate) acquired by the operating device 10.

In this operation amount derivation process, the operation locus is also derived. For example, when the user performs an operation of drawing an arc, it is derived whether the operation is performed in the forward rotation direction (clockwise) or in the reverse rotation direction (counterclockwise).

Then, the operating device 10 displays while moving the display area 14b (step S14). That is, the operating device 10 performs a display in which the display area 14b is moved based on the amount of operation. That is, the display of the adjustment value displayed in the display area 14b moves. As described above, this movement amount is determined based on the correspondence between the preset operation amount and the movement amount. Further, when the operation of drawing an arc is performed, the display moves in the same direction as the rotation direction.

Then, the operating device 10 activates the tactile sensation (step S15). That is, the operating device 10 generates a tactile sensation every time the amount of operation by the user reaches a predetermined amount. Specifically, the operating device 10 vibrates the vibrating element 17 each time it determines that a preset amount of operation has been performed. As a result, the touch sensor 15 can be vibrated to activate the tactile sensation. In addition, when the operation of drawing an arc is performed, different tactile sensations are activated according to the rotation direction. That is, the operating device 10 changes the vibration state of the vibrating element 17 depending on whether the operating device 10 is operated in the forward rotation direction or the reverse rotation direction.

Next, the operating device 10 determines whether or not there is an operation in the operating area for a certain period of time (step S15). If the user operates the operation area within a certain period of time (No in step S15), the operation amount derivation process is executed again for the operation. On the other hand, if the user does not operate the operation area within a certain period of time (Yes in step S15), the operation device 10 determines that the adjustment operation has been completed. When the adjustment operation is completed, the adjustment value displayed at that time is fixed as the changed value.

In this way, when the operation area 14a is operated, the movement amount (change amount) of the adjustment value is derived according to the operation amount from the touched position with the current adjustment value as the base point. Therefore, the operation can be performed by touching an arbitrary position in the operation area 14a. That is, if the display unit 14 can be touched in the operation area 14a without staring at it, the operation becomes possible. Further, since the tactile sensation is activated every time a predetermined amount of operation is performed, the user can recognize how much the operation has been performed even if the operation is continued without looking at the display unit 14.

<2. Second Embodiment>
Next, the second embodiment will be described. In the first embodiment, the configuration in which the user performs the adjustment operation using the touched position of the operation area 14a as the current adjustment value as the base point has been described, but the present invention is not limited to this. For example, each adjustment value may be associated with a predetermined position in the operation area 14a in advance, and the adjustment operation may be performed using the adjustment value associated with the position touched by the user as a base point. Hereinafter, the points different from those of the first embodiment will be mainly described.

First, the configuration of the operating device 20 according to the present embodiment will be described. FIG. 8 is a diagram showing a schematic configuration of the operating device 20. As shown in FIG. 8, the operating device 20 of the present embodiment stores the adjustment value information 12d in the storage unit 12 as compared with the operating device 10 described in the first embodiment. It's different. The other configuration of the operating device 20 is the same as the configuration of the operating device 10.

The adjustment value information 12d is information in which the adjustment value used when the user performs the adjustment operation and the corresponding position of the operation area 14a are associated with each other. For example, in the case of the temperature setting adjustment operation, the adjustment value information 12d is the information in which each position obtained by dividing the operation area 14a into 12 and each adjustment value of 18.0 ° C. to 29.0 ° C. are associated with each other. More specifically, the position of the upper center is set to 18.0 ° C, and the temperature is associated with 19.0 ° C and 20.0 ° C clockwise every 30 °. In this case, 26.0 ° C. is associated with the position 240 ° from the position of the upper center (from the position associated with 18.0 ° C.).

A method of performing an adjustment operation using the adjustment value information 12d will be described. 9 and 10 are diagrams illustrating a user operating the touch sensor 15 of the operating device 20. As shown in FIG. 9, when the user touches the position of 240 °, 26.0 ° C is displayed as the adjustment value on the adjustment screen. Even when the current adjustment value is 23.0 ° C., the adjustment value associated with the position touched by the user is displayed.

Then, as in the first embodiment, the display area 14b is rotated according to the amount operated by the user, and the displayed adjustment value changes. Specifically, for example, when the user draws an arc of about 120 ° and the temperature changes by 1.0 ° C., as shown in FIG. 10, when the user draws an arc of 240 °, the adjustment value is 2. It rotates by 0 ° C and 24.0 ° C is displayed in the upper center.

That is, in the first embodiment, the adjustment operation according to the operation amount of the user is executed with the current adjustment value as the base point regardless of the position touched by the user, but in the present embodiment, the user touches. The adjustment operation according to the operation amount of the user is executed with the adjustment value associated with the designated position as the base point.

Therefore, in the first embodiment, when the current adjustment value is 23.0 ° C., the adjustment operation starts from 23.0 ° C. regardless of which position of the operation area 14a is touched by the user. In the present embodiment, even if the current adjustment value is 23.0 ° C., if the position where the user's operation area 14a is touched is 26.0 ° C., the adjustment operation is performed from 26.0 ° C. ..

The number and intervals of adjustment values to be associated in advance can be set as appropriate. For example, the operation area 14a may be divided into 24, for example, instead of 12 and associated with 24 values. Further, the adjustment value associated with the position of the upper center (position of 0 °) may be set to, for example, 23.0 ° C. instead of 18.0 ° C.

Next, the processing of the operating device 20 will be described. FIG. 11 is a flowchart showing the processing of the operation device 20 according to the present embodiment. As shown in FIG. 11, the operation device 20 has a process of monitoring the display instruction of the adjustment screen (step S20), an adjustment screen display process (step S21), and a process of monitoring the presence or absence of an operation on the operation area (step). S22) and is executed. Each of these processes is the same as each process of steps S10 to S12 of the first embodiment.

Then, when the operating device 20 determines that the operation area 14a has been operated, the operating device 20 derives the adjustment value (step S23). That is, the operation device 20 derives the adjustment value corresponding to the position touched by the user based on the position information when the user touches the operation area 14a and the adjustment value information 12d stored in the storage unit 12. To do. Then, the operating device 20 displays the derived adjustment value as the adjustment start value in the upper center.

Next, the operation device 20 includes an operation amount derivation process (step S24), a display area movement process (step S25), a tactile activation process (step S26), and a monitoring process of whether or not there has been no operation for a certain period of time (step S27). ) And. Each of these processes is the same as each process of steps S13 to S16 of the first embodiment.

In this way, when the operation area 14a is operated, the movement amount of the adjustment value is derived according to the operation amount from the touched position, with the adjustment value corresponding to the touched position as the base point. Therefore, the operation can be performed with reference to the adjustment value displayed when an arbitrary position of the operation area 14a is touched. Further, since the tactile sensation is activated every time a predetermined amount of operation is performed, the user can recognize how much the operation has been performed even if the operation is continued without looking at the display unit 14.

In each of the above-described embodiments, a configuration that gives a tactile sensation each time the user's operation reaches a predetermined amount has been described. The present invention is not limited to this, and further tactile sensation can be added.

For example, in addition to the configuration in which a tactile sensation is given each time a predetermined amount is reached, a different tactile sensation may be given when a specific adjustment value is reached. The specific adjustment value is, for example, a median adjustment value (median value of temperature setting range, median value of volume setting range, equal balance position of left / right volume balance adjustment of stereo reproduction, etc.). Further, the different tactile sensations include giving a click sensation twice in a row (double click sensation). As a result, the user can not only recognize how much the operation has been performed, but also can tactilely recognize that the central adjustment value has been reached.

That is, in each of the above embodiments, the configuration in which the first tactile sensation is given for each first predetermined operation amount starting from the operation start position has been described, but in this modified example, the first predetermined operation amount is defined as. The configuration is such that a second tactile sensation different from the first tactile sensation is given each time a different second predetermined operation amount is reached.

Further, in each of the above embodiments, an example in which the predetermined amount for giving a tactile sensation is set to 30 ° has been described, but the present invention is not limited to this, and 10 ° or 15 ° can be appropriately set. Further, the interval of giving the tactile sensation may be changed according to the number of operation steps, such as giving the first tactile sensation at 30 ° and giving the second tactile sensation at 60 °. Further, the interval for giving a tactile sensation may be changed according to the adjustment target, such as changing the predetermined amount at the time of temperature adjustment and the predetermined amount at the time of air volume adjustment. In addition, a sound effect may be output in addition to imparting a tactile sensation. In this case, it is preferable to change the sound effect according to each tactile sensation.

Further, in the example of the operation of adjusting the set temperature of each of the above embodiments, when there is an operation exceeding the upper limit value or the lower limit value, the configuration in which the tactile sensation is activated when the upper limit value or the lower limit value is displayed will be described. did. However, the present invention is not limited to this. As described above, the tactile sensation may be activated at the moment when the upper limit value and the lower limit value are exceeded, but in addition, the tactile sensation may be activated for a certain period of time after the upper limit value and the lower limit value are exceeded, and the tactile sensation is always activated while the value is exceeded. It may be configured. In either case, the user can recognize that the operation exceeds the upper limit value or the lower limit value.

<3-2. Modification 2>
In the second embodiment, the configuration in which the adjustment operation is performed with the adjustment value associated with the position touched by the user as the base point has been described. The present invention is not limited to this, and the base point of the adjustment value may be set by another method.

For example, it is a method in which adjustment values are associated with a plurality of positions of a specific shape, a locus operated by a user and a corresponding portion of the shape are derived, and a base point is set. Specifically, in this modification, the adjustment value information is stored in association with a plurality of positions around the circle as shown in FIG. 12A. For example, the adjustment value of the position at 0 o'clock is 19 ° C., and the adjustment value increased by 1 ° C. is associated with the position every 30 ° in the forward rotation direction.

In this case, for example, when the user draws an arbitrary arc at an arbitrary position in the operable area of the operating device, the operating device has a position where the shape of the arc corresponds to the shape of the circle of the adjustment value information. Is derived. Specifically, when the operation as shown in FIG. 6 is performed, a portion where the operation locus of the user and the circumference coincide with each other is derived as shown in FIG. 12 (b). Then, the adjusted value of the matching circumferential portion is used as the value of the base point. In the example of FIG. 12B, the temperature is 29.0 ° C.

As described above, this modification is a method of deriving a corresponding portion between the locus operated by the user and the shape used as the adjustment value information, and setting the adjustment value corresponding to the operation start position of the user as a base point. .. As a result, even if the operation is started from an arbitrary position, the user can set the base point of the adjustment value based on the locus by operating a part of the shape used as the adjustment value information. A desired adjustment value can be set.
