2. Operation process

Hereinafter, a method of controlling the main apparatus 100 through the main apparatus 100 having the above-described components and the control apparatus 200 that may be implemented in the control apparatus 200 will be described.

2 is a flowchart illustrating an operation process of a main device and a control device according to an embodiment of the present invention.

Referring to FIG. 2, a user may input a call command for calling the first menu by operating the second operation unit 240 of the control apparatus 200 (S21).

Here, the first menu may include a group of control objects including at least one control object located at the highest level in a hierarchy of a plurality of control objects that can be selected and controlled through the control device 200 in the main device 100. Can mean. Herein, the control target may generally mean a menu for adjusting the parameter value or a shortcut menu to the control target of the lower layer. 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 first menu regardless of the currently executed application, may be changed according to the currently executed application, or may be customized by the user.

In this case, the call command may be a touch input applied to an arbitrary point on the touch pad included in the second controller 240. However, activating the touch pad to always detect the touch input input from the user in order to recognize the command input from the user for the first time may cause a problem in standby power in the second power supply 270. Therefore, in this case, the input of the call command may be performed through a specific hardware key button. If a plurality of key buttons for a call command are provided, a first menu including different control targets may be called for each key button.

When the call command is input through the second operation unit 240 in the above-described method, the second processor 210 transmits a control signal corresponding to the call command via the second interface unit 230 to the first interface unit ( 130 may be controlled to be delivered.

Accordingly, the first processor 110 of the main apparatus 200 may control the first menu to be displayed at a predetermined position on the first display unit 120 according to the control signal input through the first interface unit 130. (S22).

Preferably, the first menu including at least one control object may be arranged and displayed on a closed path, for example, on 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 the present specification, the jog dial in which the first menu is arranged in a predetermined form will be referred to as "first dial" for convenience.

When the first dial is displayed on the first display unit 120, the user may select one of the one or more control objects (that is, the first menu) disposed on the first dial in a predetermined form. The touch pad may be selected by applying a selection touch input (S23).

To this end, the touch pad of the second manipulation unit 240 is also preferably provided in a form corresponding to the shape of the closed path that the first dial takes. If the touch pad forms the touch screen integrally with the second display unit 220, the first dial may be displayed on the touch screen.

When the selection touch input is described in detail, it is assumed that a control object which the user wants to select from among one or more control objects included in the first menu occupies a predetermined area in a predetermined form on the first dial. In this case, the user may input a selection touch by applying a touch input to an area corresponding to the predetermined area on the touch pad of the second manipulation unit 240. Here, the user may release the touch state after inputting the selected touch. However, the user may maintain the touch state until the second dial, which will be described later, is displayed on the first display unit 120 or until a subsequent touch input is performed. desirable.

When the selection touch command is input through the second manipulation unit 240 in the above-described method, the second processor 210 may control the control signal corresponding to the point at which the second selection touch is applied or the control signal corresponding to the selected control target to the second. It may be controlled to be delivered to the first interface unit 130 of the main device through the interface unit 230.

Accordingly, the first processor 110 of the main device 200 is adjacent to the first dial on the first display unit 120 or is replaced with the first dial according to the control signal input through the first interface unit 130. The second dial can be controlled to be displayed (S24).

Here, the second dial refers to the second dial through a selected touch input through the touch pad of the second operation unit 240 included in the control device 200 among the plurality of control targets (that is, the first menu) displayed on the first dial. The dial for adjusting the control amount of the selected control object. If the second dial is displayed, the first processor 110 receives the control signal input through the control device 200 until a predetermined condition (for example, termination of control of the control direction through the second dial) is satisfied. It can be determined as a signal for operating the second dial.

In order to adjust the selected control amount, the second dial may display a predetermined scale on the basis of the point where the selected control target is located on the boundary area between the inside, outside or outside of the closed path or the point where the selection touch is input. have. This scale may be displayed through any one or a combination of grid lines, numbers, figures, symbols, text, thumbnails, icons, colors, and area dividing lines. In addition, the second dial on the first display unit 120 corresponding to the point where the selection touch is inputted displays the current parameter value of the selected control target, and the value less than the current parameter value as it goes counterclockwise around it, Clockwise, larger values can be displayed or vice versa. 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 farther away they may be represented as 10, 11, 12. The more specific form of such a 2nd dial is mentioned later.

On the other hand, when the second dial is displayed in a region separate from the first dial (for example, an area near the first dial) instead of being displayed by replacing the first dial, the parameter values of the control target are not a closed path. It may be displayed by being replaced by a vertical line or a predetermined graph form.

Thereafter, the user may adjust the control amount of the selected control object by dragging from the point corresponding to the selected control object, that is, the point where the selection touch is applied, on the touch pad of the second manipulation unit 240 provided in the control device 200. There is (S25).

In this case, the drag input refers to a touch pattern for changing a touch point while maintaining a touch state of a selected touch, that is, a contact state between a user input means (for example, a finger or a touch pen) and a touch pad. In this case, since the drag path is performed along the closed path of the second dial, the drag operation may be continuously or repeatedly inputted. Therefore, problems such as limitations depending on the physical size of the touch pad provided in the control device 200 can be effectively solved. In addition, the drag touch path is displayed on the second dial, and the drag path is preferably repeated within a certain range, that is, closed in the second dial. This is described in more detail below with separate drawings.

However, the present invention is not limited thereto, but a touch on a point corresponding to a desired parameter value is not dragged to a point corresponding to a desired parameter value input on the touch pad in a state where a scale indicating a parameter value of a control target is displayed. The control amount of the control target may also be adjusted as an input.

When the drag command is input through the second operation unit 240 in the above-described method, the second processor 210 transmits a control signal corresponding to the drag pattern (direction and rotation distance) through the second interface unit 230. It may be controlled to be delivered to the first interface unit 130 of 100.

Accordingly, the first processor 110 of the main apparatus 200 adjusts the control amount of the control target according to the control signal input through the first interface unit 130, and the result is displayed on the first display unit 120. It may be displayed on (S26).

Through the above-described process, the adjustment of the control amount using the dial is terminated, and according to the setting, the first dial 120 may be displayed on the first display unit 120 or both the first dial and the second dial may disappear.

According to an embodiment of the present invention, when the user does not start the selection touch within a predetermined time after the first dial is displayed, or when the user touches a point outside the area corresponding to the first or second dial on the touch pad, the first touch is performed. Or the second dial may disappear. In addition, the first or second dial may be terminated to adjust the control amount through the dial even when there is no subsequent touch input for a predetermined time after the drag input.

3. Touch input in the first dial and second dial state

Hereinafter, a general touch manipulation method of the main device control method through the control device described with reference to FIG. 2 will be described in more detail.

3 illustrates a method of controlling a control amount of a control target according to an embodiment of the present invention.

In FIG. 3, the dial represents at least a part of the touch pad included in the second manipulation unit 240 of the control device 200, and the physical form of the actual touch pad may be formed in the form of a dial as shown in FIG. 3. In addition, another touch area may be provided inside or outside the dial form. In addition, the dial form may be in the form of a first or second dial displayed on the touch screen when the second manipulation unit 240 and the second display unit 220 form a touch screen integrally.

Referring to FIG. 3, a drag path 330 may be formed along the closed path of the dial. Herein, the term “closure” is a form in which an inner region and an outer region are divided by the drag path 330 within a specific area range, and the drag path 330 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 by the desired level by the closed drag path 330 in which the path is repeated, and can freely adjust the control amount therefrom, thereby leading to the present invention. It became. Therefore, the circular drag path 330 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 corresponding to step S25 of FIG. 2 along the circular drag path 330, wherein the drag direction is forward (clockwise, A) or counterclockwise (B). Can be. 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 enlargement / reduction amount when the enlargement / reduction command is selected. 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 touch pad size.

In particular, in the present invention, the control amount is adjusted by dragging only in the drag path 330. Therefore, in one embodiment of the present invention, one or more control objects displayed on the first dial may be selected through a selection touch input applied to a point corresponding to the drag path 330. When the first dial is changed to the second dial after the selection touch, the user may immediately adjust the control direction and the control amount by performing a drag input subsequent to the selection touch along the drag path 330. According to an embodiment of the present invention, when the touch pad is provided with a separate touch area outside the drag path, the control amount control mode may be released by a user touching the external area of the drag path 330. Accordingly, the second dial may disappear or be transformed into the first dial on the first display unit and / or the second display unit.

Since the control object selection and the control method of the present invention are all made within the range of a certain area from the first touch point, the user can eliminate the inconvenience of having to touch the separate point again, and one touch and It is possible to continuously perform the control target selection and the control amount adjustment only with subsequent continuous dragging.

A detailed form in which the drag operation described above is input will be described with reference to FIG. 4.

4 is a view showing another example of a control amount adjusting method according to an embodiment of the present invention.

The same assumptions as in FIG. 3 apply to FIG. 4. Referring to FIG. 4, a user may perform a repetitive method, that is, dragging a plurality of times, from a point 320a at which a selection touch is applied on a touch pad provided as the second manipulation unit 240 of the control device 200. 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 control target selected in the first dial state is increased or decreased by a length corresponding to L (L1 + L2 + L3) which is the sum of the path distances. For example, in the case of the clockwise drag, the control amount of the control target increases, and in the reverse direction, the control amount decreases.

Particularly, in the present invention, a predetermined predetermined time condition may be set between a previously input drag and a subsequent drag. If the drag input is continued within the time range, the control amount may be increased or decreased. When exceeding, the control amount control mode may be released after the control amount adjustment corresponding to the final drag distance is performed. 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 user drag total distance until the control amount adjustment of the selected control target is completed (for example, when the user touches an external point of the dial) may be used as the control amount performance variable.

Hereinafter, a state in which the adjustment of the control amount to which the step S24 of displaying the second dial described with reference to FIG. 2 is further applied is performed will be described in detail.

5A to 5D illustrate a control amount adjusting method in which the shape of the second dial generated according to the selection of the control target according to an embodiment of the present invention is further considered.

5A to 5D, the dial represents a first or second dial displayed on the first display unit 120, and the first or second dial includes the second display unit 220 in the control device 200. If so, it may be displayed in substantially the same form on the second display unit. In addition, in each drawing, a user inputs a touch input on the first or second dial, but the user touches a point corresponding to the first or second dial through a dial-type touch pad provided in the control device. It is assumed to be an input.

First, referring to FIG. 5A, when the broadcast receiving function is executed in the main device 100 (for example, when the main device is a TV or performs a function similar to a TV), the user may display the first display through a menu call command. The first dial 500 including the first menu may be generated on the portion.

On the first dial 500, the channel 501, the volume 502, and the screen brightness 503 are disposed to be spaced apart from each other at predetermined intervals as a control target included in the first menu. 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 501 corresponding to the channel in the first dial on the touch pad.

Next, referring to FIG. 5B, since a channel is selected as a control target according to a user's selection touch, the first dial may be changed to a second dial displaying a control amount related to the channel. In more detail, the position corresponding to the point 501 to which the selection touch is applied in the second dial is displayed as No. 9, the upper channel toward the clockwise direction, and the lower channel toward the counterclockwise direction. Is displayed. Such a channel may be represented by text such as a number as shown in FIG. 5B, 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, the type of the control target in which the adjustment of the current control amount may be displayed on a part of the second dial, for example, the center 510 or outside the second dial.

The display of each channel may be displayed on the outer side of the second dial as shown in FIG. 5C. In this case, the user may drag input onto the touch screens 220 and 240 of the control device 200 in which the second dial is displayed. As a result, a problem that may occur when the channel number is covered by a finger or the like may be solved.

In FIG. 5B, in order to change the channel to 11, the user may perform a drag input from the 9th channel point 501 to which the selection touch input is applied as shown in FIG. 5D to the area where 11 is displayed, and then release the touch state. have.

The degree of the control amount (i.e., the scale) displayed on the second dial described so far may be expressed as a number as described above when the value can be quantized, but continuously when the value is not necessarily quantized. Only graphics or colors or combinations thereof may be displayed that represent a specific range or size.

Meanwhile, as described above, the drag input of the present invention may be applied a plurality of rotation methods along a closed path provided in a dial form on the touch pad when a large amount of control is adjusted. In another aspect of the present embodiment, a control amount adjusting method is provided which can additionally change the scale displayed on the second dial in response to a plurality of rotations. This will be described with reference to FIG. 6.

6A and 6C illustrate a control amount adjusting method in which a scale of a second dial is changed according to drag rotation according to an embodiment of the present invention.

First, referring to FIG. 6A, when the user wants to change the channel from 9 to 15 in the same situation as in FIG. 5B, the highest currently displayed in the 9th area 610 in which the selection touch is input on the touch pad. A drag operation may be input in a clockwise direction up to a region 12 (620) which is a channel.

As the touch point of the drag input comes up to 12 times, the second dial may be changed to display 13 to 16 new scales of regions located in the same rotational direction (that is, clockwise direction) as shown in FIG. 6B.

The user can conveniently select channel 15 by continuing the drag operation as shown in FIG. 6C 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), if the drag operation continues to the area 7 in FIG. 6A, 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. 6, the change is performed when the drag input reaches the largest number that is currently displayed. However, this is merely 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. 6 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. 4 is applied.

Meanwhile, the method of selecting a parameter value of a second range outside the first range included in the scale of the first dial displayed by changing the scale range described with reference to FIG. 6 may be implemented in other forms.

For example, if a desired parameter value does not exist in the scale displayed on the second dial after the 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 predetermined time, the next scale range (second range) of the scale range (first range) initially displayed on the second dial 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 pad (or touch screen) included in the second operation unit 240 of the control apparatus 200 according to the present invention is a capacitive touch screen that recognizes a change in capacitance and a pressure-sensitive type that recognizes a change in pressure. Both touch screens can be used. 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

If a capacitive touchscreen is used, the first range may first be displayed on the second dial as a selective 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 in at least a portion of the first display unit 120 or the second display unit 220 (including the touch screen). May be displayed. 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. 7.

7 illustrates an example of a method of displaying the pressure / area of the selected touch input according to an embodiment of the present invention.

First, referring to FIG. 7A, the pressure or area of the selected touch input is displayed in a bar graph, and when the size of the first selected touch input is 0, the first displayed range, that is, the first range is displayed. A second range larger than one range may be displayed on the second 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. 7.

The selection touch input pressure / area display method described with reference to FIG. 7 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. Can be.

As the channel is selected as the control target in the first dial, the first dial may be changed to a second dial including a number to indicate the degree of control amount for the channel as shown in FIG. 9C (a). Here, the channel 1, which is the current channel, is displayed on the second dial in an area corresponding to the point where the user's selected touch input is applied on the touch dial 241, and the closed path of the second dial is clockwise around the channel 1. The upper channel may be displayed on the screen. In addition, as shown in the drawings of FIG. 5B and below, the selected control target may be displayed in the center portion of the second dial.

In this case, the user preferably maintains the touch state at the point where the selection touch is input on the touch dial 241.

Next, the user may apply a drag input on the touch dial 241 as shown in (b) of FIG. 9D to select a desired channel. In this case, assuming that the user's desired channel is No. 7, the drag input is performed from the point where the touch selection of the touch dial 241 is applied to the point corresponding to channel 7 of the second dial, and then the channel selection is performed. After the process is completed, the selected channel 7 may be displayed on the first display unit 120.

After the drag input ends (that is, when the touch state maintained from the selected touch input is released), the second dial may disappear from the first display unit 120 or may be changed back to the first dial state.

Next, another form of the second dial will be described with reference to FIG. 10.

10A to 10B illustrate another example of a channel changing method according to an embodiment of the present invention.

It is assumed that FIG. 10A is the situation after FIG. 9B.

Referring to FIG. 10A (a), the second dial may have a form in which a control amount related to a control object selected from the first dial is displayed on the closed path around the first dial.

Next, the user may apply a drag input onto the touch dial 241 as shown in FIG. 10B to select a desired channel. In this case, assuming that the user's desired channel is 5, the drag input is performed from the point where the touch selection of the touch dial 241 is applied to the point corresponding to channel 5 of the second dial, and then the channel selection is released. After the process is completed, the selected channel 5 may be displayed on the first display unit 120.

After the drag input is terminated (ie, when the touch state maintained from the selected touch input is released), the second dial and the first dial may disappear from the first display unit 120 or may be changed back to the first dial state. .

In the above-described embodiments, the form of the touch dial 241 provided in the second operation unit 240, the number of key buttons, the correspondence with the first menu, the configuration of the first menu, and the arrangement form of the first / second dial Are all exemplary and may be variously changed as necessary. For example, when the selected control target is a channel, as described above, the control amount for the channel may be represented by a number on the second dial. However, when the selected control target is a video, "dark video", "bright image", and "sharp" Preset values such as "image" may be displayed in the form of text or an icon.

5. Second Embodiment

According to another embodiment of the present invention, there is provided a method of selecting a control target having two or more hierarchical structures and adjusting the control amount through the apparatus of the above-described configuration and the touch methods applied thereto.

The basic concept of this embodiment is explained with reference to FIG.

It is assumed that the second operation unit 240 has the same structure as in FIG. 8 described above, and in FIG. 11B, the first key button 243 is coupled to the middle of the touch dial 241 for simplicity. .

In this case, it is assumed that the third dial is divided into four regions of upper, lower, left, and right, and each region corresponds to each region of 1 to 4 of the touch dial 241. More specifically, the left area 1110 corresponds to area 4 of the touch dial 241, the upper area 1120 is in area 1, the right area 1130 is in area 2, and the lower area 1140. ) Corresponds to area 3. In addition, it is assumed that the center area 1150 of the third dial corresponds to the first key button 243.

In the above correspondence, the main device control method using the third dial according to the present embodiment assigns the touch dial 241 to the lower menu from the upper menu in the order of the area 4-1-2-3, and the flowchart of the touch. Like this. Of course, this is exemplary and the order of the operation may be changed as necessary.

More specifically, the uppermost menu may be arranged in the left region 1110 of the third dial, the next higher menu may be arranged in the upper region 1120, and the lower menu, the determination or the vertical scroll function may be arranged in the lower region 1130, and the lower region. The left and right scrolling functions may be allocated to 1140. In addition, the central area 1150 may display detailed information of the corresponding control object according to the selected control object among menus allocated to each area.

The third dial may be displayed on the first display unit 120 through the same operation as the process S21 described with reference to FIG. 2 in the above-described embodiment of the present invention.

Based on the settings in FIG. 11, a specific function control form will be described with reference to FIGS. 12 to 13.

In the following figures, the same assumptions as in FIG. 11 apply. However, the configuration of the second operation unit 240 as shown in FIG. 11B will be omitted in each drawing. Instead, "touch input" to a specific area or point of the third dial is described as applying touch input to a location corresponding to each area or point of the third dial on the touch dial 241.

12A and 12B show an example of main device function control using the third dial according to another embodiment of the present invention, respectively.

First, referring to FIG. 12A, a user may input a menu call command through a predetermined operation (eg, a hardware key button operation) on the second operation unit 240 provided in the control device 200. Accordingly, the third dial may be displayed on the first display unit 120. In this case, different groups of control targets (ie, menus) may be displayed on the third dial according to the type of key button input at the time of the menu call command.

In FIG. 12A, it is assumed that the top menu includes a channel, an image, a sound, and a control panel. However, this is merely an example, and the top menu may be variously configured as needed or customized.

When the user first changes the touch point to the position corresponding to the channel 1211 through the drag input in the uppermost menu area 1210, the automatic menu and the manual channel, which are the submenus of the channel 1211 menu, in the next higher menu area 1220. , Preference channels, etc. may be displayed. The selection of any one of the menus displayed in the top menu area 1210 may be performed by selecting a menu at the point where the touch input is released when the touch input state is released at a point on the top area 1210. . In addition, when the touch position is changed to a point corresponding to another top menu while the touch state of the drag input started on the top menu area 1210 is not released, the point where the current touch input is applied to the next higher menu area 1220. The lower menu of the uppermost menu corresponding to may be displayed.

When the top menu is selected through the drag input in the top menu area 1210 (in this case, the channel), the user may select one of the submenus of the top menu selected in the next higher menu area 1220 in the same way as in the top area, that is, You can select it by dragging. As the display menu is changed in correspondence with the current touch point of the drag input applied on the top menu area 1210, the next higher menu area 1220 is referred to as the right area 1230 of the third dial (hereinafter referred to as “third area” for convenience). The menu displayed on) may be changed in correspondence to the current touch point of the drag input applied to the next higher menu area 1220. In this case, the center area 1250 of the third dial may also be changed to correspond to the menu selected from the next higher menu.

When the user selects the auto channel menu 1221 in the next higher menu area 1220, a message is displayed in the center area 1250 of the third dial to ask whether to automatically set the channel, and the third area 1230 may accept the setting. May be displayed to determine affirmation 1231 and affirmation 1232.

Accordingly, the user may select one of positive and negative menus by dragging (or touching) the third area 1230 according to the intention of the user.

In the above-described embodiment with reference to FIG. 12A, a predetermined visual effect may be applied to a menu selected through drag (or touch) input for each region or a menu corresponding to a location where a current touch is applied to notify a user of whether the selection or touch is performed. Can be.

Next, the case where the lower end area of the third dial (hereinafter referred to as "fourth area" for convenience) is used will be described with reference to FIG. 12B.

Referring to FIG. 12B, it is assumed that the image menu 1212 is selected in the uppermost menu area 1210. As the image menu 1212 is selected as the top menu, the auto-level adjustment, screen mode setting, manual mode setting, etc. may be displayed as a submenu of the image menu 1212 in the next higher menu area 1220.
