Abstract

Provided are a control method of a touch device and a touch device using the same. A control method of a touch device according to the present invention may comprise: a step of selecting at least one control object through a selection touch input which is applied on a jog dial including the at least one control object; a step of displaying a controlled amount corresponding to the selected control object in a certain form on the jog dial; and a step of controlling the controlled amount of the selected control object depending on the distance and direction of a user's drag which is input on the jog dial from a point where the selection touch input is applied. The control method of a touch device, and the touch device having the configuration and effects, according to the present invention, may confirm one or more control objects and enable selecting one of the objects even using one hand. Furthermore, since the control direction and the controlled amount can be controlled in addition to the selection of the control object via just a simple motion such as a one-time touch and drag, a touch interface can be made more user-friendly. In addition, the controlled amount according to a control object is displayed through a scale with markings, and thus a user can easily discern and control the controlled amount which is conveniently controlled by a touch input. Particularly, the present invention allows efficient performance of complicated commands through only simple motions (drag after touch) in a touch environment where touch devices are becoming larger and complicated commands are used, to thereby have very advantageous effects.

Description

Touch device control method, touch device using same

The present invention relates to a touch device control method and a touch device using the same.

More specifically, one or more control targets can be selected with one hand, and the control amount adjustment can be freely changed without physical limitations, and the scale according to the type of the control target can be displayed to easily control the control amount. A new concept of a touch device control method and a touch device using the same.

Touch screen or touch panel means that when input means such as a person's hand or an object touches (touches) a character displayed on the screen (screen) or a specific position without using a keyboard, the touch position is detected and stored using software. Refers to a user interface device capable of processing. Examples of the touch panel include a resistive overlay, a surface acoustic wave, a capacitive overlay, and an infrared beam. The touch-based interface method is applied not only to portable small electronic devices such as mobile phones but also to large-sized electronic devices such as laptops and TVs, and it is expected that almost all interfaces will be developed based on such touch in the future.

Recently, in order to enable more complex and various touch interfaces, a multi-touch input method for extracting several touch points has emerged. However, this multi-touch input method has the inconvenience of using two hands or two fingers. In addition, as an alternative to the multi-touch technology, an interaction method based on a gesture of a single touch is disclosed. However, such a gesture-based interaction method has to distinguish the user's touch gestures recognized in the general touch mode by matching the input command with a predetermined command, thereby causing frequent errors.

In this general touch-drag type control method, one or more guide information is disclosed, the user selects a desired operation mode according to the guide information, and the operation mode is maintained according to the drag distance in the selected operation mode direction again. Discuss the technique. However, in the cited technique, since the operation mode is maintained only when the user continuously drags in the direction indicated by the arrow, the holding time of the operation mode is actually determined by the physical size of the touch screen. That is, when dragging upward in order to increase the volume, the drag range is eventually limited to the size of the touch screen, and thus the volume size that can be increased is limited by the physical size of the touch screen. In addition, the citation technique has a problem that the display of the guide information should be made in the center of the screen.

Furthermore, in the case of an enlarged touch screen, the cited technology has a very disadvantageous effect. That is, for example, when the user touches the center of the large touch screen to select the operation mode and to enlarge or reduce the image object, the user activates the guide information and then guides the guide direction (for example, up or right). Should be dragged to. However, dragging upwards on a large touch screen is limited by the height and length of the user's arm, so that the user has to physically move.

As described above, the conventional touch interface technology has a problem that the user cannot easily adjust the control amount of the command while performing various commands in a one-hand situation. In addition, in the existing touch user interface (for example, on the jog dial), if the user is not aware of the scale, the user's learning is required because the user does not know how much change should be made to what control amount. Inadvertent amounts of control may occur. In particular, when the control target is directly connected to safety, such as temperature control, safety problems may occur even when the control amount is changed without the user being aware of how much it moves.

Therefore, the first problem to be solved by the present invention is to provide a new concept of the touch device and its control method that can be freely selected and control the amount of control object even in the one-hand situation regardless of the size of the touch screen.

The second problem to be solved by the present invention is that when the control target is selected on the jog dial in which one or more control targets are displayed on the touch screen, additional information for displaying the control amount for the selected control target is displayed so that the user can change the control amount. It is to provide a new concept of the touch device and a control method thereof that can be easily understood.

In order to solve the above-mentioned problems of the general technology, the touch device control method according to the present invention is one of the at least one control object through a selection touch input applied on a jog dial including at least one control object. Which one is selected; Displaying a degree of a control amount corresponding to the selected control object on the jog dial in a predetermined form; And adjusting a control amount of the selected control target according to a distance and a direction of a user drag input on the jog dial from a point where the selection touch input is applied.

At this time, the shape of the jog dial may be any one of a circle, an ellipse or a polygon.

In addition, the one or more control objects may be displayed on the closed path of the jog dial.

In addition, the user drag is preferably performed along the closed path of the jog dial from the point where the selection touch input is applied.

In addition, the user drag may be performed continuously or repeatedly along the path, and may be repeatedly performed within a predetermined time after the last user drag is input or connected to the selection touch.

The jog dial may be a virtual jog dial displayed on a touch screen when an initial touch of a user is input.

In addition, the jog dial may be displayed at a predetermined distance from the point where the initial touch is input.

In addition, an adjustment target point of the selected control target may be set at the point where the initial touch is performed.

In addition, the jog dial may be displayed when the initial touch satisfies a preset condition. Such conditions may include the following conditions.

Whether the initial touch lasts for more than a predetermined time at substantially the same location

Whether the initial touch is repeated two or more times within a predetermined time

Whether the initial touch is above a predetermined pressure

The predetermined form in which the degree of the control amount is displayed may be any one or a combination of scales, numbers, figures, symbols, text, thumbnails, icons, colors, and area dividing lines.

The degree of the control amount may include a first control range including a control amount up to a predetermined range in which the current value of the selected control target is displayed at the point where the touch input is applied in the predetermined form, and adjusted based on the current value. The value may be displayed in the predetermined form.

The touch device control method may further include a second control range value connected to the maximum amount or the minimum amount when the user drag approaches the maximum amount or the minimum amount of the adjustable control amount displayed on the jog dial. It may further include a step displayed on.

The method may further include displaying a second control range value connected to the maximum amount or the minimum amount on the jog dial when the pressure or the touch area of the selection touch is changed. Can be.

In addition, when the time for which the selection touch is maintained at the point where the selection touch input is applied is greater than or equal to a preset time, a second control range value connected to the maximum amount or minimum direction corresponding to the stay time is displayed on the jog dial. It may further comprise the step.

In order to solve the above problems of the general technology, the touch device according to the present invention includes a touch sensing unit for recognizing a user's touch input; And

If any one of the at least one control target included in the jog dial existing on the touch sensing unit is selected by the user's selection touch, the distance and direction of the user drag input on the jog dial from the point where the selection touch is input And a controller for controlling the control amount of the selected control target to be adjusted according to the present invention.

The controller may control the jog dial to be displayed on the touch screen when an initial touch of a user is input on the touch screen.

The controller may control the jog dial to be displayed at a predetermined distance from the point at which the initial touch is input.

Whether the initial touch is above a predetermined pressure

The predetermined form in which the degree of the control amount is displayed may be any one or a combination of scales, numbers, figures, symbols, texts, thumbnails, icons, colors, and area dividing lines.

The controller may be further configured to display a first control range value including a control amount up to a predetermined range where the current value of the selected control target is displayed at the point where the touch input is applied in the predetermined form, and is adjusted based on the current value. It can be controlled to be displayed on the jog dial in a predetermined form.

The controller may further display a second control range value connected to the maximum amount or the minimum amount on the jog dial when the user drag approaches the maximum amount or the minimum amount of the adjustable control amount displayed on the jog dial within a predetermined distance. Can be controlled.

The controller may control the second control range value connected to the maximum amount or the minimum amount to be displayed on the jog dial when the pressure or the touch area of the selection touch is changed. Can be.

The controller may further include a second control range value connected to the maximum amount or the minimum amount corresponding to the dwell time when the selection touch is maintained at the point where the selection touch input is applied to the jog dial. You can control the display to

The touch device control method and the touch device according to the present invention having the above-described configuration and operation allow a jog dial including one or more control objects to be displayed even in a one-hand situation, and selects one control object. Furthermore, a simple operation such as one touch and drag can control not only the selection of the control target but also control direction and control amount thereof, thereby enabling a more user-friendly touch interface. In particular, the present invention has a very advantageous effect of efficiently performing a complicated command only with a simple operation (touch and drag) in a touch environment that is gradually enlarged and complicated to use.

In addition, according to the present invention, when a control target is selected on a jog dial on which one or more control targets are displayed on the touch screen, a scale suitable for the selected control target is displayed so that the user can easily know the distribution and change of the control amount. In addition, malfunctions can be prevented.

Hereinafter, the present invention will be described in detail with reference to the drawings. The following embodiments are provided as examples to ensure that the spirit of the present invention can be fully conveyed to those skilled in the art. Therefore, the present invention is not limited to the embodiments described below and may be embodied in other forms. In the drawings, the width, length, thickness, etc. of the components may be exaggerated for convenience. Like numbers refer to like elements throughout.

Referring to FIG. 1, one or more control objects may be displayed (S101). Here, the at least one control object is meant to include a separate menu window including a control object item that can be selected by the user. Preferably, the one or more control objects may be arranged and displayed in a predetermined form on a closed path, for example a jog dial. Here, the jog dial is exemplary, and the present invention is not limited thereto, and one or more control objects may be displayed on various shapes. In addition, the control object referred to in the present invention refers to a parameter having a current state value and whose state value can be changed according to a user's operation. Examples of such control targets include a broadcast channel, a volume, a temperature, a degree of opening and closing, the brightness of a light, a magnification control, a search for a playback point, and the like, but the present invention is not limited thereto. Should be seen. In addition, the control target may be disposed on the jog dial regardless of the currently executed application, may be changed according to the currently executed application, or may be customized by the user.

One or more control objects may be created when there is a predetermined menu manipulation through a hardware key button or a touch screen of a user or when an initial touch input is applied to an arbitrary point on the touch screen. If the jog dial is generated by an initial touch of the user, the jog dial is generated at a point corresponding to the touch point.

More specifically, the control object (ie, jog dial) generation point may be the user touch point itself, or a point spaced apart from the user touch position by a predetermined distance, or a separate area displayed on the screen (for example, the touch screen). Up / down / side or corners). As such, the one or more control point generation points can be freely set according to the size of the touch screen, the use environment, and the like, and any arbitrary generation points are within the scope of the present invention.

The generation and display of the jog dial including one or more control targets are generated when the initial touch satisfies a predetermined condition, for example, when touching the same position substantially for a predetermined time or more, when touching more than a predetermined pressure, Alternatively, the touch event condition may be a case where the same point is touched (double touch) two or more times within a predetermined time. The term “substantially” is used here to not exclude a case in which the touch position is detected to be slightly changed unlike the intention of the user. In particular, the user touch point may be a target point of an image command such as enlargement, reduction, and rotation of a screen. That is, when the user double-touches, the point may be the center point of the enlargement or reduction of the screen, or the double-touched object may be the target object of the image command. That is, the user touch point for generating the control object may be set as a target point of a command (for example, zoom-in, zoom-out, rotation, etc.) to be performed.

Thereafter, the user selects any one of the one or more control objects through a selection touch (S102).

When the control target is selected through the user's selection touch, a predetermined scale may be displayed on the basis of the point where the selected control target is located on the jog dial or the point where the selection touch is input (S103). Such a scale may be displayed through any one or a combination of scales, numbers, figures, symbols, text, thumbnails, icons, colors, and area dividing lines. In addition, the current parameter value of the selected control object is displayed at the point where the selection touch is input, so that a value smaller than the current parameter value is displayed toward the counterclockwise direction and a larger value is displayed toward the clockwise direction, or vice versa. can do. For example, if the user selects a channel as the control target, the current channel value 9 is displayed. As the counterclockwise direction moves away, channel scales 8, 7, and 6 are displayed at a predetermined interval in order, and clockwise. As it moves further, it may be represented as 10, 11, 12. This scale may be displayed on the jog dial or outside the jog dial. More specific form will be described later.

Thereafter, the user adjusts the control amount of the selected control target by dragging from the selected control target point, that is, the point where the selection touch is applied (S104). In this case, the drag input refers to a touch pattern in which a user input means (for example, a finger or a touch pen) moves while maintaining a selected touch. In particular, the inventors set the drag path in a continuous and repeating form, thereby effectively solving problems such as limitations due to the physical size of the touch screen. In addition, the drag (touch) path is displayed on the touch screen, the drag path is preferably a repeated form closed in a certain range, that is, jog dial. This is described in more detail below with separate drawings. However, the present invention is not limited thereto, and the control amount of the control target may be adjusted by a touch input to the desired parameter value instead of dragging to the desired parameter value in the state where the scale indicating the parameter value of the control target appears. .

Thereafter, the adjustment of the control amount using the jog dial is terminated, and the user's normal touch mode may proceed. In one embodiment of the present invention, termination of the control amount adjustment of the one or more control objects is completed by the jog dial including the one or more control objects disappearing on the screen.

In one embodiment of the present invention, the user does not initiate the selection touch within a predetermined time after the initial touch, or the jog dial where the user touches a point outside the jog dial generated by the initial touch disappears, and for a predetermined time after the drag input Even if there is no subsequent touch input, the adjustment of the control amount via the jog dial is terminated.

Hereinafter, a general touch manipulation method according to the present invention except for the scale display step (S103) of the jog dial described with reference to FIG.

2A and 2B, when a user touches a point 210 of the touch screen according to a preset touch event method, one or

more control objects

220a, 220b, and 220c may have a jog dial in an appropriate size. Created and displayed. In FIG. 2, the

control targets

220a, 220b, and 220c disposed on the jog dial are three in total, but the present invention is not limited thereto, and more or fewer controlled items may be generated according to the use environment. , Which belongs to the scope of the present invention. In addition, the one or more control objects may take various forms, and any form belongs to the present invention, as long as the user recognizes the control object and selects it by a touch method, and the forms illustrated in FIGS. 2A and 2B. The present invention is not limited thereto.

In addition, in one embodiment of the present invention, the user's touch point 210 may set a target range of control. For example, when the user wants to select a zoom-in, the zoom center point may be the user touch point 210. As such, when the user touches a point to perform image control such as enlargement, reduction, or rotation, according to a preset touch event condition, a desired command is performed based on the point.

After the touch, the user activates it by touching a desired control object (eg, channel 220a of FIG. 2B) of one or more control objects disposed on the jog dial. The touch selection of the control target may be performed by dragging a finger to a control target which the user wants to select again after touching the one point 210 or touching a point 210 within a predetermined time or by touching an external point of the control target. The specific control target may be touched again until the control target ends. Thereafter, the control direction and the control amount of the selected control object are controlled by the user in the drag direction and length from the point (220a of FIG. 2B) corresponding to the touch-selected specific control object.

To this end, an embodiment of the present invention displays a closed repeating path between the control objects, which will be described with reference to FIG. 3.

3 is a view showing a control control method according to an embodiment of the present invention.

Referring to FIG. 3, a drag path 230 may be formed along the closed path of the jog dial. Herein, the term “close” is a form in which an inner region and an outer region are divided by the drag path 230 within a specific region range, and the drag path 230 may be repeated. For example, the drag path, that is, the shape of the jog dial may be a polygon such as a circle, a triangle, a rectangle, or the like. The present inventors focus on the fact that the user can drag the path as much as the user desires by the closed drag path 230 in which the path is repeated, and the control amount can be freely adjusted, thereby leading to the present invention. It became. Accordingly, the circular drag path 230 shown in the drawing is for illustrating the closed drag path, and the present invention is not limited thereto.

The user performs a drag input along the circular drag path 230, and the drag direction may be forward (clockwise, A) or counterclockwise (B). In one embodiment of the present invention, when the drag is in the forward direction, the control direction and / or control amount of the selected control object (where the control direction or control amount represents the increase or decrease of the selected command and the increase or decrease amount thereof). If it is selected, it means the increase / decrease of the volume size, which means the increase / decrease amount when the enlarge / reduce command is selected), and the control amount decreases in the reverse direction. Furthermore, in the present invention, when the user drags the desired level along the closed drag path, the control amount of the selected control object may be freely adjusted and controlled without physical limitations according to the size of the touch screen. In particular, in the present invention, the control amount is adjusted by dragging only in the drag path 230. Therefore, in one embodiment of the present invention, the one or more control objects are provided on the drag path 230, and after the user selects one of them, the user immediately drags along the drag path 230, thereby controlling the control direction and The control amount is adjusted. In one embodiment of the present invention, when the user touches an external area of the drag path 230, the control amount control mode is released, so that the control object may disappear at a time or gradually on the screen.

Since the control amount selection and the control method of the present invention are all made within the range of the user from the first touch point, it is possible to eliminate the inconvenience that the user has to touch again a separate point of the remote, one touch and Subsequently, only the subsequent dragging can continuously perform the control object selection and the control amount adjustment.

A detailed form to which the above-described method of selecting a control target and a control amount adjustment method are applied will be described with reference to FIG.

In FIG. 4, it is assumed that a TV viewing function is performed on a display device having a touch screen to which a control method using a jog dial according to the present invention is applied.

When the jog dial is displayed through any one of the above methods, when the user touches the channel 220a as a control target and then drags the jog dial clockwise, the channel number can be moved in a higher direction. have. If the user touches the volume 220c as a control target, the volume increases when the user drags the jog dial clockwise.

The present invention proposes another method in which the control amount is controlled even when the drag method is not only continuous but also when the drag method is repetitive.

Referring to FIG. 5, a user performs an iterative manner, that is, a plurality of drags, from one or more control object 220a points. The drag distance is L1 at the first time, and the drag distance is two times, L2 at three times. At this time, in the present invention, the control amount of the selected control object 210a is increased or decreased by a length corresponding to L (L1 + L2 + L3), which is the sum of the path distances. do. In particular, in the present invention, a predetermined predetermined time condition is set between the first touch and the continuous touch, and if the touch is continuous within the time range, the control amount increases or decreases, and when the time range exceeds the control amount The control mode is released. However, all of the above examples merely represent an embodiment of the present invention, and a method without setting the time range is also possible. For example, the total user drag distance until the control target ends (for example, when the user touches an external point to be controlled) may be used as the control variable performance variable.

Hereinafter, a state in which the adjustment of the control amount to which the step S103 displaying the dial scale described with reference to FIG. 1 is further applied is performed will be described in detail.

First, referring to FIG. 6A, when the broadcast reception function is executed, the user may cause the jog dial 600 including one or more control targets to be generated through an initial touch or a predetermined menu operation.

On the jog dial 600, the channel 601, the volume 602, and the screen brightness 603 are arranged to be spaced apart from each other by a predetermined interval. In this case, the types of the control objects are displayed in text, but the types may be replaced with a symbol or an icon corresponding to the control objects.

In this case, when the user wants to change the channel, the user may apply a selective touch with a finger (or a corresponding operation means) to the area 601 corresponding to the channel on the jog dial.

Next, referring to FIG. 6B, when the channel is selected as the control target according to the user's selection touch, the current channel No. 9 is displayed at the position 601 to which the selection touch is applied, and the upper channel gradually moves clockwise around it. The lower channel is displayed as it goes counterclockwise. Such a channel may be represented by text such as a number as shown in FIG. 6B, or may be in the form of a graphic, an icon corresponding to each channel, or a thumbnail of a current broadcast content. The area corresponding to each channel may be visually divided into colors or lines. In addition, in some areas of the jog dial, for example, the center 610, the type of the control target for which the current control amount is being adjusted may be displayed. At this time, the control targets shown in FIG. 6A may disappear from the jog dial.

The display of each channel may be displayed on the outside of the jog dial as shown in FIG. 6C. In this case, a problem that may occur when the channel number is covered by a finger or the like as the user performs a drag input may be solved.

In FIG. 6B, in order to change the channel to 11, the user may perform a drag input from the 9th channel point 601 to which the selection touch input is applied as shown in FIG. 6D to the area where 11 is displayed, and then release the touch state. have.

The degree of the control amount (ie, the scale) corresponding to the control object selected according to the selection touch described so far may be expressed as a number as described above when the value may be quantized, but when the value is not necessarily quantized. Only graphics or colors or combinations thereof may be displayed that represent the approximate range or size in succession.

On the other hand, as described above, the drag input of the present invention may be applied a plurality of rotation methods along the closed path on the jog dial when adjusting a large amount of control. Another embodiment of the present invention provides a control amount adjusting method capable of additionally changing the scale in response to a plurality of rotations. This will be described with reference to FIG. 7.

First, referring to FIG. 7A, when the user wants to change the channel from No. 9 to No. 15 in the same situation as in FIG. 6B described above, No. 12, which is the highest channel currently displayed in the No. 9 area 710 in which a selection touch is input, The drag operation may be input to the area 720 in a clockwise direction.

As the drag operation comes up to 12 times, the jog dial may be changed such that the scales of areas 13 to 16 are newly displayed as shown in FIG. 7B.

The user can conveniently select channel 15 by continuing the drag operation as shown in FIG. 7C and continuing to area 15 and then releasing the touch. If the user wants to change to the upper channel exceeding 16, the channel 11 after 11 may be changed to the channel 17 after the drag input up to 16.

On the contrary, if the touch is performed in the opposite direction (i.e., counterclockwise), when the drag operation continues to the area 7 in FIG. 7A, the jog dial is changed so that the channel number is sequentially displayed from the area 12 from the number 12. Can be. In this case, in FIG. 7, the change is performed when the drag input reaches the largest number that is currently displayed. However, this is an example. The range in which the dial scale change is triggered may be changed as necessary. For example, the direction in which the desired parameter value exists within a predetermined time or within a predetermined distance from the point where the selection touch is applied (ie, clockwise or counterclockwise) is not changed to the next range when the largest value or a specific value is reached. The scale range can be changed by returning to the original position after applying a short drag input with). In addition, according to the triggering of the dial scale change, the range of the newly displayed scale may be changed as necessary.

Although the scale change method described with reference to FIG. 7 has been described with reference to a plurality of rotations, it should be noted that the method may be applied in a similar manner even when the repeated drag input of FIG. 5 is applied.

Meanwhile, the method of selecting the parameter value of the second range outside the first range included in the scale displayed initially by changing the scale range described with reference to FIG. 7 may be implemented in other forms.

For example, if the desired parameter value does not exist in the scale displayed on the jog dial after the first selection touch, the user may keep the touch state at the point where the selection touch is applied without inputting a drag operation. Accordingly, when the selection touch input is maintained for more than a preset time, the next scale range (second range) of the first displayed scale range (first range) may be displayed. After the next scale range is displayed, the touch state is continuously maintained, and when the preset time elapses, the next scale range (third range) may be displayed. In this case, the direction in which the scale changes from the first range to the second range and the third range (that is, the direction in which the parameter value increases or decreases) may be preset by the user. Thereafter, when a range of parameter values desired by the user is displayed, the user may input a drag operation following the touch input or may directly apply a touch input to a desired value in order to select a desired value.

As another form of selecting a parameter value of a second range outside the first range included in the first displayed scale by changing the scale range, a method of changing the pressure or area applied with the selection touch may be used.

As described above, the touch screen according to the present invention may use both a capacitive touch screen that recognizes a change in capacitance and a pressure sensitive touch screen that recognizes a change in pressure. In this case, the capacitive touch screen may recognize the change of the touch area in a plurality of steps, and the pressure sensitive touch screen may recognize the magnitude of the pressure of the touch input in a plurality of steps. Hereinafter, a method for changing the scale range according to the present invention for each type of touch screen will be described.

1) When capacitive touch screen is used

When a capacitive touch screen is used, the first range may first be displayed on the jog dial as the selection touch is applied. In this case, the first range is preferably a range including the current parameter value of the selected control target as described above. In this case, the user may make the touch area larger while maintaining the selected touch (for example, when the pointer is a finger, the user may increase the touch area by pressing harder). As such, a second range that includes values greater than the first range may be displayed on the jog dial. If the user changes the touch state to an area smaller than the area to which the selection touch is applied, a second range including values smaller than the first range may be displayed. In the above-described method, the touch area and the range of parameter values have been described as being proportional, but the present invention may be implemented in the reverse case.

2) When a pressure sensitive touch screen is used

When a pressure sensitive touch screen is used, the first range may first be displayed on the jog dial as the selection touch is applied. In this case, the first range is preferably a range including the current parameter value of the selected control target as described above. In this case, the user may make the touch pressure larger while maintaining the selected touch (for example, when the pointer is a finger, the user may increase the touch pressure by pressing harder). As such, a second range that includes values greater than the first range may be displayed on the jog dial. If the user changes the touch state to a pressure lower than the pressure at which the selection touch is applied, a second range including values smaller than the first range may be displayed. In the above method, the touch pressure and the range of the parameter values have been described as being proportional, but the present invention may be implemented in the reverse case.

However, the pressure or the touch area may be difficult for the user to intuitively recognize. To this end, information indicating the size of the current touch pressure / touch area and the pressure / area value for displaying the next range value may be displayed on at least a portion of the touch screen. Such pressure / area values can be displayed in various forms. For example, the pressure / area value may be displayed in numbers, colors, graphs, figures, text, or a combination thereof. This will be described with reference to FIG. 8.

First, referring to FIG. 8A, when the pressure or area of the selection touch input is displayed as a bar graph, when the size of the initial selection touch input is 0 and reaches the +1 range, the first displayed range, that is, the first A second range larger than one range may be displayed on the jog dial, and a third range larger than the first second range may be displayed upon reaching the +2 range.

The pressure / area of the selection touch input may be displayed in the form of a needle and a scale as shown in (b) of FIG. 8.

The selection touch input pressure / area display method described with reference to FIG. 8 is exemplary, and the present invention is not limited thereto, and the present invention may be implemented in the form of voice, sound effect, or haptic effect (for example, vibration) that informs the user of the pressure / area.
