TOUCH-SENSING DEVICE AND METHOD FOR CONTROLLING THEREOF}

The present invention relates to a touch sensing device and a control method thereof.

More specifically, when the control amount is adjusted by rotating drag during touch input, a new concept of a touch sensing device control method capable of freely rotating drag input without displaying any rotation center point or rotation guide display information, and a touch sensing device using the same It is about.

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, an interface for adjusting a control amount through a rotary touch input has been introduced. Here, the control amount is a concept that collectively refers to the parameters whose value can be adjusted according to a user's input. For example, the sound output volume, channel, and screen brightness may be used. In the case of such an interface, since a rotation command must be input based on a predetermined center point, a display of the center point or a touch wheel guide line should be shown to the user. Otherwise, the user may not be aware of the center point of rotation and may be manipulated by leaving the center point.

As described above, the conventional rotary touch interface technology determines the center point and determines the rotation input direction and distance according to the change of the angle of the rotation input of the user. Therefore, it is inevitable to cover the content on the screen because the user should present the rotation center and guideline in some form. In addition, the user should keep inputting while recognizing the center point in order to prevent the wrong command from occurring due to the rotational input of which the center point is deviated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a new concept of a touch sensing device and a control method thereof, which can freely adjust a control amount of a control target through a rotating touch input without worrying about the deviation of the rotation center point without any center point and rotation guide display information on the touch screen. To provide.

Another object of the present invention is to provide a touch sensing device and a method of controlling the same, which can conveniently adjust a control amount even in a specific situation in which an input is limited such as a lock screen.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not restrictive of the invention, unless further departing from the spirit and scope of the invention as defined by the appended claims. It will be possible.

According to an aspect of the present invention, there is provided a method of controlling a touch sensing device, the method comprising: receiving coordinate values according to a rotational drag of a user; Determining an inclination using a change in the coordinate value; determining a drag rotation direction using a change in the sense of increase of the coordinate and the inclination value; And controlling the touch sensing device according to the distance and the direction of the user drag.

Through the mobile terminal according to at least one embodiment of the present invention configured as described above, the user may more conveniently adjust the control amount by using the rotary touch input. In particular, the rotation input is not limited to the size of the physical screen, and the present invention which efficiently performs the rotation drag command without worrying about the deviation from the center point conveniently in a touch environment where its usefulness is very important as an operation method that does not limit the use command.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now 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, but 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.

The touch sensing device described herein includes a mobile phone, a smart phone, a laptop computer, a digital broadcasting terminal, a personal digital assistant (PDA), a portable multimedia player (PMP), a navigation device, a remote controller, and a tablet computer. A part of the mobile terminal may be configured as shown in FIG. However, it will be readily apparent to those skilled in the art that the configuration according to the embodiments described herein may also be applied to fixed terminals such as digital TVs, desktop computers, etc., except when applicable only to mobile terminals.

In the following embodiments, it is assumed that the touch control method according to the present invention is performed on a touch sensing device including a touch screen that recognizes a touch input and a controller that performs an operation using a trajectory of the recognized touch input. A more specific configuration of the touch sensing device will be described later with reference to FIG. 7.

Judging the direction and center point of a rotary touch input

In general, when a jog dial or a touch wheel is displayed on the touch screen or a circular shape of the touch pad is displayed in a multimedia device having a touch sensing device, the size or center point of the touch wheel will be determined. In this case, it is relatively simple to determine whether the touch input along the trajectory of the touch wheel is a rotation input in the entity responsible for the control function. However, when such a touch wheel is not displayed on the touch screen and it is not assumed that a touch input is always input within a fixed range, a method of determining whether a trace of the touch input is drawn in a circle is required. Hereinafter, the touch trajectory determination method proposed by the present invention will be described with reference to FIGS. 1 and 2.

1 is a flowchart illustrating a touch screen control method for determining a direction and a distance of a rotary touch input according to an exemplary embodiment of the present invention.

Referring to FIG. 1, a coordinate value of a touch-drag input detected on a touch screen is acquired continuously or at predetermined periods (S101).

Thereafter, the slope value may be calculated according to the change of the coordinate value during the predetermined period (S102).

It may be determined whether the trajectory of the touch-drag input detected based on the change in the sense of the increase in the input coordinate value and the tilt value is a circular drag or a circular drag, and in which direction the direction of rotation is the drag.

As a result of the determination, when the corresponding touch-drag input is a rotational drag, the control amount may be adjusted according to the direction and length of the trajectory (S104).

In this case, the control amount to be adjusted may be a control amount last adjusted by an arbitrary method before the rotation drag touch sensed through the above-described method is input, or preset to be adjusted by the rotation drag touch sensed through the above-described method. It may be a controlled amount. In addition, the control amount to be adjusted may be changed according to the situation in which the rotation drag touch sensed through the above-described method is input.

In the above-described control method, a specific criterion for determining the change in the increase and decrease of the coordinate value and the tilt value will be described in more detail with reference to FIG. 2.

FIG. 2 is a diagram illustrating a touch screen control method for determining a rotation direction and distance according to a change in a sense of increase in coordinate values and inclination during a rotation touch input according to an embodiment of the present invention.

Referring to FIG. 2, the rotation drag input may be divided into four sections. (210, 220, 230, and 240) In each of the divided sections, the coordinate values (x, y) and the slope values 250 are determined according to the rotation direction. As the increase of) changes in an organic manner, it can be operated by grasping the intention of which direction the user wants to adjust even if the center point is not determined using the feature. In FIG. 2, the coordinate system and the tilting method according to the two-dimensional x and y axes are shown. However, the present invention is not limited thereto, and various coordinate systems and tilt values may be generated according to a use environment, which is within the scope of the present invention. Belongs.

In addition, the circle presented in the form of the rotary drag touch shows an ideal circular shape, but this is exemplary and the present invention is not limited thereto and may be applied to a rotary drag touch of more various shapes.

Specific Example

As described above, the control target controlled by the control method described with reference to FIGS. 1 and 2 may be changed according to a command input performed last, and may be fixed to one at all times. In addition, the present control method may be executed at all times or may be executed in a specific situation.

As an example in which the control amount is adjusted regardless of the position of the rotary drag trajectory in any situation, when a music playback application is executed in which a touchwheel of a prepared type is not displayed, the track search is performed at an arbitrary position on the touch screen after the last song search is performed. When the rotation drag touch is input, the music search may be performed. In addition, if the rotation drag touch is input at an arbitrary position on the touch screen after the volume adjustment is performed, the volume adjustment may be performed. The relationship between the direction of the search or volume control and the rotational direction (for example, an increase in the value in the case of clockwise rotation) may be set in advance.

On the contrary, as an example of being executed in a specific situation, various menu icons are displayed on the touch screen, and thus, when a rotation drag touch is input, the above-mentioned rotation drag trajectory may not be determined even if there is a touch input due to a possibility of malfunction. . Instead, when the touch input is detected only when a preset trigger condition is satisfied, such as when the menu icon is not displayed, the above-described rotation drag trajectory may be determined.

A description with reference to FIGS. 3 to 6 is as follows.

3 is a flowchart illustrating an example of a control method of a touch sensing apparatus according to a specific condition according to an embodiment of the present invention.

First, it may be determined whether a preset trigger condition is satisfied (S310). Examples of the trigger condition may include a lock screen state to be described later, a screen off state, and a state in which a specific hardware key button is operated.

When the touch input is detected when the trigger condition is satisfied (S320), it may be determined whether the corresponding touch input is a rotational drag using the coordinates and the slope according to the trajectory of the touch input (S330).

If it is determined as the rotation drag input, the control amount may be adjusted according to the direction and distance of the rotation drag (S340), otherwise, another function according to the determined touch trajectory may be performed (S350).

A case in which a specific trigger condition under which the above-described control method is performed is a lock screen situation will be described with reference to FIGS. 4 to 6.

Here, the lock screen situation refers to a case in which another input is restricted after the touch screen is gradually turned off or immediately turned off, for example, because a command is not input for a predetermined time from the user, before a command for releasing the situation is input. In a lock screen situation implemented in a mobile terminal, a predetermined content is generally displayed in a lock screen state, and when this state is released, the user can return to the last displayed screen or enter a desktop (home screen).

4 is a display state diagram illustrating an example of a volume control mode and a lock screen state according to an embodiment of the present invention.

First, referring to FIG. 4A, a volume control mode is displayed on a touch screen. More specifically, the virtual dial 410 for adjusting the volume is displayed, above which a gauge 420 indicating the size of the current volume is displayed. When the touch-drag input is detected in the clockwise direction along the trajectory of the virtual dial 410, the gauge 420 may be filled with increasing volume.

In this state, if there is no input detected on the touch screen for a predetermined time, the touch screen gradually becomes dark as shown in (b) of FIG. 4, and then nothing is displayed on the touch screen.

If the touch screen is applied again after the touch screen is turned off or a hardware key button provided in the device including the touch screen is manipulated, the lock screen may be displayed as shown in FIG. In the lock screen, a time display function, which is a preset content, and a slide rail 430 and a slide bar 440 for releasing the lock screen are displayed instead of the volume adjustment mode displayed last before entering the present state. When the user drags the slide bar 440 to the opposite end of the slide rail 430, the lock screen may be released.

According to the assumption, the lock screen is activated to satisfy the trigger condition to which the rotation drag determination method according to the present invention is applied. Adjustment of the control amount through the rotation drag accordingly will be described with reference to FIG.

5 is a display state diagram illustrating an example in which volume adjustment is performed in response to a rotation drag input in a lock screen state according to an embodiment of the present invention.

In FIG. 5, it is assumed that the control amount adjusted through the rotary drag touch is the last adjusted control amount (ie, volume).

Referring to FIG. 5A, in a locked screen state, a user inputs a clockwise rotational drag touch on a touch screen using a finger 510. As the trigger condition is satisfied and the rotation drag is sensed, although the virtual wheel for adjusting the volume is not displayed, the volume adjustment may be performed according to the direction and distance of the rotation.

Meanwhile, as shown in FIG. 5B, the volume gauge 520, which is an adjustment target of the control amount, may be displayed on the lock screen according to the detection of the rotation drag touch.

A case in which the touch input sensed in the lock screen state is not the rotation drag touch will be described with reference to FIG. 6.

6 is a display state diagram illustrating an example of performing a function according to a touch input instead of rotating drag in a lock screen state according to an embodiment of the present invention.

Referring to (a) of FIG. 6, the lock screen state is released as the slide bar 620 is dragged from the original position 630 to the opposite side of the slide rail 640 by the finger in the lock screen state. The volume control mode that was displayed last may be displayed as shown in (b) of FIG.

The above-described volume control mode, the method for releasing the lock screen, etc. are all exemplary, and the present invention is not limited thereto and may be applied to more various control amount adjustment modes, lock screen forms, and trigger conditions.

As described above, another example of the trigger condition may be a touch screen off state. The screen off state refers to a state in which nothing is displayed on the touch screen. Since the touch itself can be detected even if there is no content displayed on the touch screen, even if no touch wheel or menu icon is displayed on the touch screen, a specific control amount can be adjusted when the rotary drag touch is recognized. have.
