Description

  The present invention relates to a user interface device including a display that displays an image and a touch panel that enables an operation with a finger.

  Conventionally, user interface devices equipped with touch panels have been widely used. In particular, in recent years, in user interface devices such as smartphones, tablet computers, electronic books, PDAs (Personal Digital Assistants), so-called portable information devices, touch panels have been actively adopted as user interfaces that accept operations by finger contact. ing.

  If a touch panel is adopted, various input operations corresponding to the multi-functionality of the device can be performed. However, on the other hand, compared to physical keys, there is a tendency for erroneous input operations to occur. Specifically, an input operation occurs even when the user unintentionally touches the touch panel, or even if the user performs an input operation, a desired function is not activated and a redo operation is required.

  There is a technique for giving a tactile response by vibration or the like to an operated finger as a measure for dealing with the problem of erroneous input. The user can perform an operation with reference to obtaining a response (feedback) to the operation performed by himself / herself, and can obtain the response with a finger to confirm the completion of the operation.

  For example, Patent Document 1 discloses a touch panel device that vibrates a multi-touch panel that can detect a plurality of contacts that occur simultaneously and performs feedback of touch confirmation. In this device, when the first finger touches, the first vibration is applied to the finger, and when the second finger touches while the first finger is touching, the vibration level is higher than the first vibration. A large second vibration is applied.

  Further, Patent Document 2 discloses an input device that performs notification in a notification mode set in a button area when one of a plurality of button areas allocated on the detection surface of the touch panel is touched. . Here, this notification form is any one of vibration, sound, color, and brightness, or a combination thereof.

  Conventionally, depending on a portable information device, various switch images are displayed on a display screen, and a device operation parameter value such as a sound volume in audio output is set by operating the image with a finger.

  At this time, when the parameter takes a plurality of discrete values, for example, when the sound volume can be set in a plurality of stages, the setting of the parameter value becomes troublesome depending on the displayed switch image. For example, in the case of a push button image, a plurality of button images are required, or an operation such as pressing a plurality of times is required. Further, in the case of a slide switch image or a dial switch image, when these switch images are slid or rotated, it is difficult to stop the operation at the scale position corresponding to the discrete value. As a result, the parameter value setting is considerably troublesome.

  This problem is not solved by simply using a conventional technique such as that described in Patent Documents 1 and 2 and simply reporting feedback such as touch confirmation or vibration. In particular, unlike the case where the physical switch is actually operated, the discrete value parameter must be set only by the operation by the touch of the finger. Therefore, it is very difficult to obtain operability with a sense of security and reliability that the setting operation has been performed reliably and that the setting operation has been completed.

It is a flowchart which shows one Embodiment of the parameter setting method in the portable information device by this invention.

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

In the user interface device according to the present invention,
(1) A setting part image having a movable part and setting a parameter value, wherein a setting part image including a plurality of setting areas in which the movable range of the movable part is separated from each other is displayed on a display screen. ,
Next, the displayed setting part image is contacted and pushed in with a finger. Here,
(2) The finger contact position is included in the display position range of the movable part, the pressing force of the finger is not less than a predetermined threshold, and the finger contact position is one of a plurality of setting areas. When entering the position range corresponding to the set area, a tactile response is given to the finger via the touch panel,
(3) It is characterized in that the parameter is set to a value assigned to this one setting area.

  As described above, the setting unit image is an emulation of a parameter setting switch such as a slide switch or a dial switch. Therefore, when viewed from the user's operation, when the movable part of the setting part image is pushed with the finger and the finger is slid toward one setting area to which the target value is assigned, the physical assumed by the setting part image It is also possible that a vibration that is recognized as having been moved into a predetermined position by moving the movable part of the switch is applied as a tactile response.

  Here, the parameters are parameters that define the operation of the device / equipment. For example, the volume at the output of voice / alarm, the amount of light at the display (output of optical information), the vibration at the occurrence of vibration by the vibrator Intensity, a virtual physical quantity in a phenomenon / event that occurs in the displayed virtual space (for example, in the game space), and the like. This parameter takes a discrete value and becomes a jump value. For example, if the volume is a discrete value corresponding to a plurality of levels from zero to the maximum volume, if the vibration intensity is a discrete value corresponding to three levels of weak, medium and strong, 1 if the battle experience value of the battle game To a natural number from 5 to 5.

  The finger contact position is represented as one coordinate point in the plane coordinate system set on the surface of the touch panel. Depending on the touch panel, finger contact can be detected as a contact surface having a certain area (a plurality of contact areas). In this case, the coordinates of the position of the center of the contact surface (center coordinates on each coordinate axis) Can be the contact position.

  Many of the user interface devices according to the present invention are portable information devices such as smartphones and tablet computers that can be carried with one hand or both hands and can be operated with fingers of the held hand. Therefore, hereinafter, a portable information device will be described as an embodiment of the present invention.

  1A to 1C are a front view of a portable information device and a schematic diagram of a displayed setting unit image for explaining parameter setting in the portable information device according to the present invention.

  According to FIG. 1 (A), the portable information device 1 is arranged on a display 101 for displaying a setting unit image for setting parameter values, and on the screen of the display 101. A touch panel 100 that sequentially detects the response and a tactile response mechanism 102 that gives a tactile response (vibration) to a user's finger that touches the touch panel 100 (screen of the display 101).

  In the portable information device 1, a turntable application emulating a turntable capable of scratching, which is a performance method for producing a special sound by shifting the record board back and forth, is activated. Specifically, a turntable 104 as a turntable image is displayed on the screen of the display 101. The user can perform a performance including scratches and output music by operating the turntable 104 with a finger.

Furthermore, in this turntable 104,
(1) a slide switch 105, which is a setting unit image in which the number of rotations (33, 45, and 78) of the record board as a parameter can be set;
(2) A dial switch 106 is displayed, which is a setting unit image that can set the volume of the performance sound as a parameter (eight levels including zero).

As shown in FIG. 1B, the slide switch 105 includes a knob 105a that is a movable part and has a mark 105b, and a scale 105c. The mark 105b of the knob 105a is a parameter instruction position indicating the scale 105c corresponding to the parameter value. The marker 105b is, when any one opposed tick 105c is a parameter value corresponding position, rotation speed (parameter) _{P r} is set to one of three predetermined values (33 rpm, 45 rpm and 78 rpm) Is done.

The movable range RM (which can be defined by a unit of length (mm)) of the knob 105a (the mark 105b) is separated from each other and has three setting areas R ₃₃ , R ₄₅ and R ₇₈ (one scale 105c). It can be specified in units of length (mm). Each of these settings zones _{R 33, R 45} and _{R 78,} as the rotation speed (parameter) _{P r} value, 33, 45 and 78 are assigned.

The user moves (slides) the finger while pressing the knob 105a by bringing the finger into contact with the knob 105a. By this operation, the user moves the knob 105a so that the mark 105b is opposed to the scale 105c in the set area to which the desired rotation speed (parameter) _Pr is assigned. As a result, the rotational speed (parameter) _{P r} is set to a desired value (33, 45 or 78).

On the other hand, as shown in FIG. 1C, the dial switch 106 includes a rotating part 106a which is a movable part and has a mark 106b, and a scale 106c. The mark 106b of the rotating unit 106a is a parameter instruction position indicating the scale 106c corresponding to the parameter value. The marker 106b is, when any one opposed tick 106c is a parameter value corresponding positions, the volume (parameter) P _s is set to one of eight predetermined values (natural numbers of 0 and 1 to 7) .

The movable range RMa of the rotating portion 106a (the mark 106b) (which can be defined in the unit of angle (°)) is separated from each other and has eight setting areas Ra ₀ , Ra ₁ , Ra ₂ , Ra each having one scale 106c. ₃ , Ra ₄ , Ra ₅ , Ra ₆ , Ra ₇ , and Ra ₈ (which can be defined in angular units (°)). Each of these settings areas, as the volume (parameter) P _s value, a natural number of 0 and 1 to 7 are assigned.

The user moves (slides) the finger so as to draw an arc with the finger while bringing the finger into contact with the rotating unit 106a and pushing the rotating unit 106a. User This action rotates the rotating portion 106a, the mark 105b, to scale 106c and the counter of the desired volume (parameter) settings _{area P s} is assigned. As a result, the volume (parameter) P _s is set to a desired value (any one of 0 and a natural number of 1 to 7).

  2A to 2E are a schematic diagram of the slide switch 105 and a schematic diagram of an operation with a finger for explaining an operation on the slide switch 105 displayed on the portable information device 1.

According to FIG. 2 (A), first, the user, the knob 105a of marker 105b is facing the scale 105c rpm _P r = 78 of assigned set region _{R 78,} contacting the finger. That is, the finger contact position is included in the display position range of the knob 105a. Next, as shown in FIG. 2B, the user pushes the knob 105a with his / her finger and points the finger toward the scale 105c of the setting area R ₄₅ to which P _r = 45 is assigned (FIG. 2 (B ) To move to the left).

At this time, the operation with the finger is accepted, to the parameter setting operation is started, the pressing force p _c with respect to the touch panel 100 by the finger, the pressing force threshold as p _th,
(1) _pc ≧ p _th
The value must satisfy the condition of As a result, it is possible to obtain operability with a sense of security and reliability that the operation for parameter setting is performed reliably. Here, the pressing force threshold value p _th can be set to a value in the range of 0.5 N (Newton) to 1.0 N, for example.

  It should be noted that when the finger contact position 107 is included in the display position range of the knob 105a (that is, immediately after contact), the movable range RM direction between the finger contact position 107 and the mark 105b of the knob 105a (left and right in FIG. 2). The difference in (direction) is calculated and determined in advance. Thereafter, using this difference, the mark 105b of the knob 105a is determined from the contact position 107 every moment.

Next, in accordance with the movement of the finger contact position as shown in FIG. 2B, the tactile response mechanism unit 102 applies vibration v ₁ as a tactile response to the finger via the touch panel 100. It is also preferable that the vibration v ₁ becomes stronger as the displacement of the finger contact position per unit time elapses. Accordingly, a sense of resistance that is generated when the physical slide switch whose position is likely to be settled for each scale is actually slid and removed from the settled position is obtained by tactile sensation.

Here, knobs 105a also according to the movement of the contact position of the finger (to the left) towards the scale 105c setting area _{R 45} moves. At this time, the knob 105a may move following the finger, but it is also preferable to move the knob 105a by a smaller moving amount than the moving amount of the finger. Alternatively, it may remain stationary despite the finger movement initially. By displaying the knob 105a in this way, it is possible to visually obtain a sense of resistance when actually starting to slide a physical slide switch whose position is easily adjusted for each scale.

In addition, when the contact position of the moved finger goes out of the display position range of the slide switch 105, the knob 105a (the mark 105b) is moved to the initial setting area R ₇₈ as in the case where the finger is separated from the touch panel 100. It is also preferable to display to return to the position. This is similar to a situation in which a physical slide switch is slightly slid and the finger is immediately released, and is intuitively easy to accept as a visual response.

Then, as shown in FIG. 2 (C), further moves (slides) the finger, the mark 105b of the knob 105a that moves in accordance with movement of a contact position 107 of the finger, a position range corresponding to the set area R ₇₈ The tactile response mechanism unit 102 stops the vibration v _{1 applied} to the finger when it goes outside. Further, the mark 105b is sequentially displayed at a position where the finger contact position 107 at each time point is displaced by the above-described difference.

Therefore, as shown in FIG. 2D, as the finger contact position moves toward the setting area R ₄₅ (to the left), the knob 105a (the mark 105b) follows the movement of the finger. It moves together with the finger contact position 107.

Then, as shown in FIG. 2 (E), the finger and thumb 105a moves further, knob mark 105b of 105a is, upon entry into the position range _{R f1} corresponding to the setting area _{R 45,} rotational speed (parameter ) Is set to the value (P _r = 45) assigned to this setting area.

Further, at this time, the tactile response mechanism unit 102 applies the vibration v ₂ for a relatively short time to the finger. As a result, an operational feeling that can be recognized as moving the movable part of the physical switch assumed by the slide switch 105 into a predetermined position is obtained tactilely.

In order to obtain a more realistic haptic response, the haptic (vibration) received by the finger when the physical slide switch is slid with the finger may be actually sampled. It is also preferable to apply a vibration having a pattern similar to the vibration pattern collected by this measurement as a tactile response (vibrations v ₁ and v ₂ ) in accordance with the movement of the finger.

Further, the mark 105b of the knob 105a is at the set upon entry into the position range _{R f1} corresponding to the area _{R 45,} at once (or quickly move _to), set zone _R within ₄₅ P r = 45 is assigned It is also preferable to display at a position facing the scale 105c. Furthermore, it is also preferable that the operation sound generation unit 108 (FIG. 5), which will be described later, generates an operation sound of an image in which a physical slide switch fits in a fixed position, such as “click”. As a result, a feeling of operation when the physical slide switch is actually slid out can be obtained visually and also audibly.

As described above, by performing the operation with a finger to the slide switch 105 displayed on the portable information device 1, the parameter (number of revolutions) P _r taking discrete values, easily, with a realistic feeling of operation It is understood that it is configurable.

  3A to 3E are a schematic diagram of the dial switch 106 and a schematic diagram of an operation with a finger for explaining an operation on the dial switch 106 displayed on the portable information device 1.

According to FIG. 3 (A), first, the user, the rotating portion 106a of mark 106b is graduated 106c facing the volume _P s = 3 of assigned set area Ra _3, contacting the finger. That is, the finger contact position is included in the display position range of the rotation unit 106a. Next, as shown in FIG. 3B, the user draws an arc toward the scale 106c of the setting area Ra ₄ to which P _s = 4 is assigned while pushing the rotating unit 106a with the finger. (Clockwise in FIG. 3B).

At this time, the operation with the finger is accepted, to the parameter setting operation is started, the pressing force p _c with respect to the touch panel 100 by the finger, the pressing force threshold as p _th, the above Expression (1) p _c ≧ The value must satisfy the condition of p _th . As a result, it is possible to obtain operability with a sense of security and reliability that the operation for parameter setting is performed reliably. Here, the pressing force threshold value p _th can be set to a value within the range of 0.5 N to 1.0 N, for example, as in the case of the slide switch 105 described above.

  Incidentally, at the beginning (that is, immediately after contact) of the finger contact position 107 included in the display position range of the rotation unit 106a (that is, immediately after contact), the movable range RMa direction between the finger contact position 107 and the mark 106b of the rotation unit 106a (FIG. 2). The difference (angle difference) in the circumferential direction is calculated and determined in advance. Thereafter, using this difference, the mark 106b of the rotating portion 106a is determined from the momentary contact position 107.

Next, along with the movement of the finger as shown in FIG. 3B, the tactile response mechanism unit 102 applies vibration v ₁ to the finger as a tactile response via the touch panel 100. It is also preferable that the vibration v ₁ becomes stronger as the (angle) displacement of the finger contact position per unit time elapses. As a result, a sense of resistance that is generated when the physical dial switch whose position is easily settled for each scale is actually rotated and removed from the settled position is tactilely obtained.

The rotation part 106a is also in accordance with the rotational movement of the contact position of the finger, (clockwise) towards the scale 106c setting area Ra ₄ rotates. Here, the rotating unit 106a may rotate following the finger, but it is also preferable that the rotating unit 106a rotate by a smaller amount of rotation (amount of angular displacement) than the amount of movement of the finger (the amount of rotation). Alternatively, it may remain stationary despite the finger movement initially. By displaying the rotating unit 106a in this way, a sense of resistance when a physical dial switch whose position is easily settled for each scale is actually started to be rotated can be visually obtained.

In addition, when the contact position of the moved finger goes out of the display position range of the dial switch 106, as in the case where the finger is separated from the touch panel 100, the rotating portion 106a (the mark 106b) is set to the initial set area Ra. It is also preferable to display to return to the position of ₃ . This is similar to the situation where the physical dial switch is rotated slightly and the finger is immediately released, and is intuitively easy to accept as a visual response.

Then, as shown in FIG. 3 (C), the finger is further moved, the mark 106b of the rotating part 106a which is moved in accordance with movement of a contact position 107 of the finger is outside the range of positions corresponding to the setting area Ra ₃ , The tactile response mechanism 102 stops the vibration v _{1 applied} to the finger. Further, the mark 106b is sequentially displayed at a position where the finger contact position 107 at each time point is displaced by the above-described difference (angle difference).

Accordingly, as shown in FIG. 3 (D), with the moving contact position of the finger toward the set area Ra _4, the rotation section 106a (mark 106b) of the contact of the finger to follow the movement of the finger It rotates together with the position 107.

Then, as shown in FIG. 3 (E), the fingers and the rotating part 106a moves further, when mark 106b of the rotating part 106a has entered the range of positions _{R f2} corresponding to the setting area Ra _4, volume ( Parameter) is set to the value (P _s = 4) assigned to this setting area.

Further, at this time, the tactile response mechanism unit 102 applies the vibration v ₂ for a relatively short time to the finger. As a result, a sense of operation that is recognized as having been moved into the predetermined position by moving the movable part of the physical switch assumed by the dial switch 106 is obtained tactilely.

In order to obtain a more realistic tactile response, the tactile sense (vibration) received by the finger when the physical dial switch is rotated with the finger may be actually sampled. It is also preferable to apply a vibration having a pattern similar to the vibration pattern collected by this measurement as a tactile response (vibration v ₂ ) in accordance with the movement of the finger.

Further, the mark 106b of the rotary unit 106a, set when entering the area Ra ₄ in position range _{R f2} corresponding, at once (or quickly rotate _with) set area Ra _{4 which P} s = 4 is assigned It is also preferable to be displayed at the position (the position of the scale 105c). Furthermore, it is also preferable that the operation sound generation unit 108 (FIG. 5), which will be described later, generates an operation sound of an image in which a physical dial switch fits in a fixed position, such as “click”. As a result, a feeling of operation when the physical dial switch is actually turned off can be obtained visually and also audibly.

As described above, by operating the dial switch 106 displayed on the portable information device 1 with a finger, the parameter (volume) P _s taking discrete values can be easily set with a realistic operational feeling. It is understood that it is possible.

The touch panel 100 is arranged on the screen of the display 101, sequentially detects the contact position of the user's finger as time passes, and outputs the contact position information to a contact position determination unit 121 described later. As this touch panel 100, for example, a projected capacitive touch panel, a surface capacitive touch panel, a resistive touch panel, an ultrasonic surface acoustic wave touch panel, an infrared scanning touch panel, or the like can be employed.

  The tactile response mechanism unit 102 gives a tactile response (vibration) to the finger touching the touch panel 100 by vibrating the touch panel 100. The tactile response mechanism 102 can be a piezoelectric actuator formed using a piezoelectric material such as PZT (lead zirconate titanate).

Pressing force detection unit 103 detects the pressing force _{p c} applied to the touch panel 100 by the finger. Pressing force detection unit 103 is, for example, are placed under the four corners of the touch panel 100, the touch panel 100 flexed pressed against the finger the total pressing on itself, is detected as the pressing force p _c. The pressing force signal output by the pressing force detection unit 103 is input to a pressing force determination unit 122 described later. The pressing force detection unit 103 can be, for example, a piezoelectric sensor formed using a piezoelectric material such as PZT. In addition to or in addition to providing the tactile response mechanism unit 102 formed of a piezoelectric actuator, the pressing force detection unit 103 can be used as a tactile response mechanism unit.

  The operation sound generation unit 108 is an acoustic element such as a speaker that can generate a sound corresponding to an operation with a finger.

  Similarly, according to FIG. 5, the functional configuration unit (processor memory) includes a setting unit image control unit 120, a contact position determination unit 121, a pressing force determination unit 122, a tactile response control unit 123, and a parameter setting unit 124. An operation sound control unit 125, a display control unit 110, and an application processing unit 111.

The display control unit 110 is instructed to display on the screen 101. The setting unit image information is output to the contact position determination unit 121, the tactile response control unit 123, the parameter setting unit 124, and the operation sound control unit 125.

The pressing force determination unit 122 inputs a pressing force signal from the pressing force detection unit 103. Then, the pressing force determining section 122, based on this signal, determines the magnitude of the pressing force p _c by finger whether a predetermined pressing force threshold p _th least. Further, the pressing force determination unit 122 outputs the determination result to the setting unit image control unit 120, the tactile response control unit 123, the parameter setting unit 124, and the operation sound control unit 125.

  The contact position determination unit 121 inputs a contact position signal from the touch panel 100. Also, the setting unit image information is input from the setting unit image control unit 120. Next, the contact position determination unit 121 determines whether or not the finger contact position is included in the display position range of the movable part based on these signals and information, and the determination result and the movement information of the finger contact position. Are sequentially output to the setting unit image control unit 120, the tactile response control unit 123, the parameter setting unit 124, and the operation sound control unit 125.

  Further, when the contact position determination unit 121 performs true determination by itself and the pressing force determination unit 122 determines true, the setting unit image control unit 120 sets the movable part to a position corresponding to the finger contact position. Display sequentially. Here, the contact position determination unit 121 determines the relationship between the finger contact position and the parameter value instruction position (for example, the mark 105b) of the movable part at the beginning when the finger contact position is included in the display position range of the movable part. Determine the difference in the direction of movement. Next, the difference information is output to the setting unit image control unit 120.

It is also preferable that the setting unit image control unit 120 inputs a determination result and finger contact position movement information from the contact position determination unit 121 and inputs a determination result from the pressing force determination unit 122. In this case, in the setting unit image control unit 120, the contact position determination unit 121 determines true, the pressing force determination unit 122 determines true, and the parameter value indicating position (for example, the mark 105b) of the movable part is determined. When the movable portion moves within a position range corresponding to one setting area among a plurality of setting areas (for example, R ₃₃ , R ₄₅ and R ₇₈ ) of the setting portion image (for example, the slide switch 105), Thus, the display control unit 110 displays the parameter value indicating position of the movable part so as to face the scale 105c which is the parameter value corresponding position provided in the one setting area.

  Further, the tactile response control unit 123 determines that the contact position determination unit 120 is true, the pressing force determination unit 122 performs true determination, and the parameter value indicating position of the movable part is one of a plurality of setting areas. When the parameter value indicating position moves in accordance with the movement of the finger contact position, the tactile response to the finger via the touch panel 100 is opposed to the parameter value corresponding position (for example, the scale 105c) in the set area. It is also preferable to instruct the tactile response mechanism unit 102 to apply (vibration).

The parameter setting unit 124 receives the determination result and the finger contact position movement information from the contact position determination unit 121, inputs the determination result from the pressing force determination unit 122, and further receives the setting unit image information from the setting unit image control unit 120. input.

Next, based on these determination results and information, the operation sound control unit 125 performs a true determination by the contact position determination unit 121, a determination by the pressing force determination unit 122, and a parameter value indicating position (for example, , The mark 105b) enters a position range corresponding to one setting area of a plurality of setting areas (for example, R ₃₃ , R ₄₅ and R ₇₈ ) of the setting portion image (for example, the slide switch 105), The operation sound generator 108 is instructed to generate a sound for recognizing that the movable part (for example, the knob 105a) is fitted in a predetermined position.

  The display control unit 211 inputs the application processing information from the application processing unit 212 and causes the display 201 to display an image corresponding to the execution of the application. In addition, the display control unit 211 causes the display 201 to display the setting unit image in response to an instruction regarding the setting unit image output from the setting unit image control unit 120.

  FIG. 6 is a flowchart showing an embodiment of a parameter setting method in the portable information device 1 according to the present invention.

(S600) First, a setting part image (for example, the slide switch 105) is displayed on the screen of the display 101. Here, the parameter (for example, record board rotation speed P _r ) is set to an initial value (for example, 33, 45, or 78), and the position of the movable part (for example, the knob 105a) is assigned by this initial value. Displayed within a designated set area (eg, R ₃₃ , R ₄₅ or R ₇₈ ).

(S601) Next, the contact position of the finger with respect to the touch panel 100 is measured.
(S602) Next, it is determined whether or not the contact position of the finger is included in the display position range of the movable part. Here, when true determination is made, that is, determination is made that the finger is included in the display position range of the movable part, the parameter setting loop by the finger (steps S610 to S621) is entered. On the other hand, if a false determination is made, the process returns to step S601 again, and the contact position of the finger (contact presence / absence) is monitored.

(S610, S611) after entering the parameter setting loop (step S610～S621), by the pressing force detection unit 103, the pressing force _{p c} applied to the touch panel 100 is detected by the finger.
(S612) Next, the magnitude of the pressing force _{p c} is equal to or a predetermined pressure threshold _{p th} least.
(S613) Here, the true determination, i.e. when the pressure force p _c is made a determination that the predetermined threshold value p _th least, measuring the contact position of the finger on the touch panel 100. On the other hand, when a false determination is made, the process proceeds to step S621 to determine whether or not the finger is in contact with the touch panel 100.

(S614) After step S613, the movable part is displayed at a position corresponding to the finger contact position.
(S615) Next, it is determined whether or not the parameter value indicating position (mark) of the movable part is within the position range corresponding to the setting area to which the parameter initial value is assigned. Here, when the true determination is made, a tactile response (vibration) corresponding to the displacement of the contact position of the finger is applied to the finger (step S630), and the process proceeds to step S621.

(S616) On the other hand, when a false determination is made in step S615, that is, when it is determined that the parameter value indicating position (mark) of the movable part is not within the position range, the parameter value indicating position ( It is determined whether or not the mark) is within a position range corresponding to one of the plurality of setting areas.
(S617) Here, when the true determination is made, the parameter is set to the value assigned to the setting area. On the other hand, when a false determination is made, the process proceeds to step S621, and it is determined whether or not the finger is in contact with the touch panel 100.

(S618, S619, S620) After step S617 (or together with step S617), a tactile response (vibration) is given to the finger for a predetermined time, and the parameter value indication position (mark) of the movable part corresponds to the parameter value in this setting area. An operation sound is generated by moving the movable part so as to face the position (scale). Thereafter, the process proceeds to step S621, and it is determined whether or not the finger is in contact with the touch panel 100.

(S621) If it is determined that the finger is in contact, the finger parameter setting loop started from step S610 is repeated. On the other hand, if it is determined that the finger is not touching, the parameter setting method is terminated, assuming that the operation with the user's finger is completed.
