Description

Touch screen control method, a touch screen device using the same, and mobile phones and portable electronic devices including the same {tools for touch panel, and mobile devices using the same}

The present invention relates to a touch screen control method, a touch screen device using the same, and a mobile phone and a portable electronic device including the same. More particularly, a touch screen control method capable of effectively performing various commands even in a one-handed situation, using the same A touch screen device, and a mobile phone and a portable electronic device including 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. Recently, in order to enable more complex and various interfaces, a multi-touch input method for extracting several touch points has emerged. However, the multi-touch input method overlooks the fact that the operation of a mobile device is often performed by one hand, and has the inconvenience of using two hands or two fingers. In addition, as an alternative to the multi-touch technique, an interaction method based on a gesture of a single touch is disclosed. However, such a gesture-based interaction method needs to match a user's touch gesture recognized in a general touch mode with an input command gesture. The matching process uses a complex equation and an algorithm to change the coordinate value of the user input means and its change. The method proceeds by formulating a value and comparing it with a preset formula. That is, the conventional gesture-based interaction method has a multi-step process of gesture recognition → matching process → command execution, and thus, there is a problem that it is difficult to promptly and promptly execute a user touch gesture. Furthermore, in the conventional gesture-based interface method, as described above, a user's normal touch gesture must be distinguished from a touch gesture (command gesture) for performing a predetermined command (for example, zooming in, zooming out, or rotating). do. However, this process is very difficult in the current touch interface environment in which various and complex user touch gestures are performed, and there is a problem of generating frequent errors.

Therefore, the first problem to be solved by the present invention is to provide a new concept touch screen control method that can effectively implement a variety of commands even in a one-hand situation.

The second problem to be solved by the present invention is to provide a touch screen device of a new concept that can effectively implement a variety of commands even in a one-hand situation.

The third object of the present invention is to provide an application device utilizing the touch screen device.

In order to solve the first problem, the present invention comprises the steps of generating a marker at the virtual touch position corresponding to the user's touch position in accordance with the user's touch event conditions; Moving the virtual touch position in response to the movement of the touch position of the user, thereby performing at least one of the following commands: i) a first command according to a change in distance between the user touch position and the virtual touch position; A touch screen control method is performed according to a rotation angle of the user touch and includes a second command different from the first command. In an embodiment of the present invention, the touch event condition of the user is substantially the same. The touch is maintained for a predetermined time or more, and in another embodiment of the present invention, the user touch pressure is greater than or equal to the predetermined pressure.

In another embodiment of the present invention, the user touch position movement is in a drag type, and the virtual touch position corresponds to point symmetry of the touch position. In addition, the rotation angle may be calculated from a center point between the virtual touch position and the touch position of the user. The rotation angle or the user's touch movement path may be displayed on the touch screen, and the execution amount of the second command is determined in proportion to the change amount of the rotation angle.

In one embodiment of the present invention, the second command may be one of the following commands.

-Switch to previous or next object

-Play the previous or next video medium

-Rewind or fast forward the video medium

-Increase or decrease display or voice information

In another embodiment of the present invention is performed after the step of controlling the touch screen to perform the first or second command, the time interval between the user's touch termination and resumption of the touch screen is a predetermined criterion If it is greater than the time, the above-described touch screen control step is stopped, and the above-described touch screen control step continues for the time interval more than the predetermined reference time. In addition, when the above-described touch screen control step is interrupted, the label may gradually disappear for a predetermined time. Furthermore, when the user touch does not correspond to the touch event condition, the touch screen may be controlled so that the object is moved according to the movement of the touch position without displaying the cover.

The first command may perform the reduction when the touch position moves in a direction in which the distance between the touch position and the virtual touch position decreases, and the enlargement may be performed when the touch position moves in the direction in which the interval increases.

In order to solve the second problem, the present invention is a touch sensor unit for detecting a touch position; A controller configured to calculate and generate a virtual touch position corresponding to the touch position when the user's touch sensed by the touch sensor unit corresponds to a preset event, and perform at least one of the following commands; i) a first command according to a change in distance between the user touch position and the virtual touch position; ii) a second command which is performed according to a change in the rotation angle of the user touch and is different from the first command; And a display unit which is controlled by the control unit, displays a mark at the virtual touch position, and displays an object on which the command is performed. In one embodiment of the present invention, the user's touch event condition is whether the touch is maintained at the same position for a predetermined time or more or the user touch pressure is greater than or equal to the predetermined pressure.

The rotation angle is calculated from the center point between the virtual touch position and the user's touch position. According to another embodiment of the present invention, the rotation angle or the user's touch movement path is displayed on the touch screen, and the execution amount of the second command may be determined in proportion to the change amount of the rotation angle. In one embodiment of the present invention, the virtual touch position may correspond to point symmetry of the touch position, and the second command may be one of the following commands.

-Switch to previous or next object

-Play the previous or next video medium

-Rewind or fast forward the video medium

-Increase or decrease display or voice information

In the first command of the present invention, the reduction may be performed when the touch position moves in a direction in which the distance between the touch position and the virtual touch position decreases, and the enlargement may be performed when the touch position moves in the direction in which the interval increases. .

In order to solve the third problem, the present invention provides a mobile phone or a portable electronic device including the touch screen device described above.

The touch panel input method and apparatus of the present invention having the above configuration and operation can effectively perform a command such as zooming in or zooming out in a one-handed situation by setting a separate mode instead of a normal object moving mode. Furthermore, in the above mode, various commands can be effectively and quickly performed through a touch type that generates a user's touch movement, in particular, a rotation angle of the user's touch. In particular, the conventional gesture-based interface method has to distinguish between a user's normal touch gesture (for example, movement of an object) and a touch gesture for performing an input command (for example, rotation) in the same mode. In a real mobile environment in which touch gestures are performed, it is very difficult to distinguish between a typical touch gesture and a touch gesture performing a pre-input command, and a complex algorithm for distinguishing the touch gestures is used. Particularly in the limited computing conditions of mobile devices, these complex processes are triggered at a slow rate, which is very inconvenient for users. However, the present invention divides the touch into two modes (normal mode and virtual mode), and performs the command based on only the variable of the rotation angle in the virtual mode. Innovative improvements.

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 by way of example so that those skilled in the art can fully understand the spirit of the present invention. 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.

1 is a flowchart illustrating a touch screen control method according to the present invention.

Referring to FIG. 1, first, a normal touch mode (hereinafter, referred to as “normal mode”) in which an object is moved (scrolling or the like in the case of web browsing) is performed. Thereafter, the user touch event determines whether the preset condition is satisfied (S110), and if the user touch event satisfies the preset condition, a so-called “virtual mode” is generated in which a new virtual touch position is generated (S200). Various touch events may be used as the user touch event condition. For example, the touch position may be touched substantially the same position for a predetermined time or the reason that the term “substantially used” may be changed slightly unlike the intention of the user. In this case, a touch event such as a touch over a predetermined pressure is possible. However, various touch event conditions may be set according to the device environment, and any condition is within the scope of the present invention as long as it is distinguished from a general touch mode. In addition, the number of touches is not only single touch (touch by one input means) but also multi-touch by a plurality of input means.

A virtual touch position is calculated and generated at a position corresponding to the user touch position, and in one embodiment of the present invention, a mark is generated at the virtual touch position (S200). The virtual touch position generation position may be a point of symmetry with a user touch position in an object.

Thereafter, two commands are performed according to the touch method, and the touch method is a rotation angle according to a distance change between the user touch position and the virtual touch position and / or the user touch position movement (S210). The command performed according to the distance change of the touch position is referred to as a first command (S220). As an example of the first command, if the user touch position is moved in a direction in which the distance between the touch position and the virtual touch position is reduced, performing the reduction (zoom-out) of the object is determined. The performance of (zoom-in) is determined. The movement of the touch position may be a movement by dragging, where the drag means moving while the input means is in contact with the touch screen.

In addition, the present invention discloses a configuration for performing a second command according to the user touch rotation angle change in the virtual mode. The reference point of the rotation angle is a center point between the user touch position and the virtual touch position. That is, according to the present invention, according to the change in the distance and rotation angle between the virtual touch position and the user touch position, the enlargement, reduction, or switching to the previous or next object is performed.

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

Normal mode

2 is a view showing an example of the operation of the touch screen device during the normal mode (S100). Referring to FIG. 2A, when the inside of the object 310A is touched and dragged, the object 310A moves. In the figure, 310A, 310B, 330A, and 330B indicate an object before movement, an object after movement, a touch position before movement, and a touch position after movement, respectively.

Referring to FIG. 2B, when touching and dragging the entire screen 340, which is a kind of object (object), the objects 350A and 360A included in the desktop 340 simultaneously with the movement of the entire screen 340. Go too. In the figure, 350A and 360A represent objects before movement and 350B and 360B represent objects after movement. In the figure, 370A indicates the touch position before the movement and 370B indicates the touch position after the movement.

Virtual mode

3 is a diagram illustrating a virtual mode according to an embodiment of the present invention.

Referring to FIG. 3, when a user input means (for example, a finger) touches a specific point A in the object 310A of the touch screen 100 for a predetermined time or more, the center point of the object 310A is determined. The virtual touch position is generated at the point B which is point symmetrical with reference, and the symmetrical positional relationship between the user touch position and the virtual touch position persists in the virtual mode. However, the touch event in which the virtual mode is executed may be not only the touch time but also a touch pressure, and the present invention is not limited thereto. In addition, the center point can be freely set by the user.

In addition, a cover may be displayed on the generated virtual touch position to help the user's intuitive understanding. In one embodiment of the present invention, the cover has a finger shape. However, the present invention is not limited thereto.

After the virtual touch position is calculated and generated according to the touch event condition, two commands are performed, one of which is a first command based on a distance change touch, and the other is based on a rotation angle change touch. It is a second command different from the command. This will be described in detail below.

First command

4 is a diagram illustrating a first command according to an embodiment of the present invention. The first command described below is enlarged or reduced, but the following all illustrate the present invention, and another command according to a change in distance between the user touch position and the virtual touch position is possible, which is also within the scope of the present invention. .

Referring to FIG. 4, when dragging is performed such that an interval between the touch position 410A and the virtual touch position is increased, an enlargement of the object 420A is performed. That is, the virtual touch position representing the relative symmetry moves in the same direction when the user's touch position 410A moves in the center direction of the object, so that the distance between the touch position 410A and the virtual touch position is shortened. On the contrary, when the user touch position is far from the center direction, the distance between the touch position 410A and the virtual touch position becomes long. In the present invention, the object is enlarged and reduced by utilizing such a relative length change. For example, the magnification ratio ((square root of area after magnification-square root of initial area) / (square root of initial area) of the object 420A is the rate of change of the distance between the touch location 410A and the virtual touch location ((after change). Distance-initial distance) / (initial distance)). As another example, the magnification of the object 420A may be proportional to the rate of change of the distance between the touch position 410A and the center point 425. In the drawings, 410B, 415B, and 420B represent a touch position after enlargement, a cover after enlargement, and an object after enlargement, respectively. As represented in the figure, the virtual touch position may move according to the movement of the touch position 410A. In this case, the path of the moving virtual touch location may correspond to the point symmetry of the path of the moving touch location 410A. The point may, for example, be located inside the object 420A and may be the center point 425 of the object 420A. Unlike the drawing, the virtual touch position may be fixed regardless of the movement of the touch position 410A.

Referring to FIG. 4B, when the touch positions 430A remain the same for a predetermined period or more, the mark 435A is displayed at the virtual touch position. The virtual touch position may be located inside the background screen 450 which is the object selected by the touch. The touch location 430A and the virtual touch location may have a symmetric relationship with the center point 455 of the desktop 450. Unlike the drawing, the touch position 430A and the virtual touch position may not have a center point 455 symmetry relationship. Thereafter, when dragging is performed such that the distance between the touch location 430A and the virtual touch location is reduced, the reduction of the objects 440A and 445A included in the desktop 450 is reduced along with the reduction of the desktop 450. Is performed. As an example, the reduction rate ((square root of area after reduction minus square root of initial area) / (square root of initial area) of objects 440A and 445A is the rate of change of distance between touch location 430A and virtual touch location ( It can be proportional to (distance after change-initial distance) / (initial distance). As another example, the reduction ratio of the objects 440A and 440B may be proportional to the rate of change of the distance between the touch position 430A and the center point 455. In the drawings, reference numerals 430B and 435B denote touch positions after reduction and marks after reduction, respectively. Also, reference numerals 440B and 445B denote objects after reduction.

Second command

The present invention discloses a configuration in which a second command different from the first command is performed when a rotation angle change occurs due to a user drag gesture in a virtual mode in which the first command is performed. Here, the gesture refers to a user touch movement that generates a change in coordinate value or angle.

5 is a view for explaining a change in rotation angle according to an embodiment of the present invention.

Referring to FIG. 5, a virtual touch position 510 corresponding to the user touch position 520 is calculated and generated. The virtual touch position 510 corresponds to a point symmetrical position with respect to the user touch position 520 with respect to the center point 530. The virtual touch position 510 is based on the center point 530 according to the movement of the user touch position 510. The rotation angle is generated. For example, in FIG. 5, it can be seen that a rotation angle of θ2 in the clockwise direction B and θ1 in the counterclockwise direction A occurs. The present invention executes the second command through the rotation angle change. For example, in one embodiment of the present invention, the reference value of the angle change may be preset to an arbitrary value. In this case, when the rotation angle exceeds the preset reference value, the second command is performed. In particular, the gesture-based second command is performed in a virtual mode distinct from the normal mode. Thus, a more effective and clear gesture-based command is possible as compared with the prior art which recognizes and executes a gesture-based command in a normal mode in which a complex touch gesture is performed. Furthermore, if the rotation angle by the user's drag continuously changes and exceeds the preset value, the second command (for example, object conversion) is performed immediately, so that no matching process based on a complicated algorithm is required. Since the second command can be executed only by comparing the rotation angles, very quick and immediate gesture-based commands can be executed.

In the present invention, the second command may be any command including the enlargement and reduction. For example, the enlargement may be performed when the rotation angle is increased, and the reduction may be performed when the rotation angle is decreased. In particular, in a command requiring continuous increase or decrease (for example, a command in which the command amount is continuously changed, such as voice volume or image contrast), the continuous change in the rotation angle corresponds to the increase or decrease in the command amount. You can. In particular, the method according to the present invention has a rotation angle limit of two-finger rotation of the conventional multi-touch technology-when two fingers are rotated once while maintaining a touch state, it is difficult to rotate more than 180 degrees, 360 degrees rotation Is to overcome the limitation that is physically impossible, it is possible to search the object or the like, or to control the sound volume in a continuous manner as many times as desired with one finger.

Some examples of the second command will be described below in detail with reference to the drawings. However, all of the examples described below should be understood to explain and illustrate the present invention, and the present invention is not limited to the following examples.

FIG. 6 is a view for explaining object switching among second commands according to an embodiment of the present invention, wherein the object may be a part or a full screen on a full screen.

Referring to FIG. 6, a virtual touch location 510 corresponding to the touch location 520 of the user is generated according to the above-described touch event condition, and an enlargement or reduction command is performed according to the distance change thereof. Furthermore, when the user's touch position rotates clockwise (A) or counterclockwise (B) in the virtual mode (that is, when a rotation angle occurs), an object such as a next screen or a previous screen is accordingly The transition is made. That is, in FIG. 6, when the clockwise rotation gesture occurs, the object (full screen) is switched to the next page of the web browsing command and the previous page in the counterclockwise direction.

This approach has a particularly advantageous effect over the prior art, in that it is possible to switch between continuous objects. For example, if the preset command rotation angle is A, when the user makes a rotation gesture in a clockwise direction and the rotation angle is generated by A, it is converted to the next object, and then rotates again by A with the user's continuous rotation gesture. When an angle occurs, it can be switched to the next or previous object. That is, in the present invention, even if the user rotates only one finger continuously, the object can be changed as many times as infinite. Such object switching may be applied to a plurality of objects as described above, and the previous or next object may be sequentially converted and displayed according to the rotation angle.

In addition, in consideration of user convenience, the rotation angle information or command information 540 and / or the touch position movement path may be displayed on the screen.

7 is yet another view for explaining the second command according to the present invention.

Referring to FIG. 7, enlargement and reduction may be performed according to a change in the distance of the virtual touch location 510 corresponding to the touch location 520 of the user, as described above. Furthermore, when the user's touch takes the form of a touch that rotates clockwise (A) or counterclockwise (B), the volume of sound increases in the clockwise direction and the volume of sound decreases in the counterclockwise direction. In this case, the angle change amount of the user touch position 520 and the virtual touch position 510 is applied to determine the increase or decrease of the sound volume. That is, the sound volume is increased when the continuous increase of the rotation angle in the clockwise direction is recognized, and the volume of the sound decreases when the increase in the rotation angle in the counterclockwise direction is recognized. This method can be applied to continuously changing not only voice information such as sound but also display information such as contrast and contrast. That is, the first and second commands according to the present invention have a very advantageous effect compared to the conventional gesture-based command in that the user can arbitrarily adjust and control the amount of commands (degree of increase or decrease). In addition, in an embodiment of the present invention, information 540 of the command and the command amount according to the change of the rotation angle may be displayed on the screen.

8 is yet another view for explaining the second command of the present invention.

Referring to FIG. 8, according to a change in the relative position of the virtual touch position 510 corresponding to the touch position 520 of the user, enlargement and reduction may be performed, as described above. Furthermore, when the user's touch makes a rotational gesture in the clockwise direction A or counterclockwise direction B, the fast forward command is performed in the clockwise direction, and the rewind command is performed in the counterclockwise direction. Similarly, play of the next or previous video medium may be performed based on the touch movement that generates the rotation angle. In this case, as shown in FIG. 8, a separate mark (command information and command amount information) indicating a second command system based on the rotation angle may be displayed on the screen.

email mode  End

The virtual mode for executing the above-described first or second command is terminated, and the normal mode is started again. In an embodiment of the present invention, the virtual mode is terminated according to the steps shown in FIG. 9.

Referring to FIG. 9, first, after the touch on the touch screen is terminated in the virtual mode, the time T1 between resuming the touch and the preset reference time Td are compared. Thereafter, when T1 is larger than Td, the virtual mode ends, and when it is small, the virtual mode is maintained. In this case, it is possible to solve the problem of the user having to resume the touch event again to maintain the virtual mode.

Furthermore, an embodiment of the present invention discloses a configuration of maintaining the mark of the virtual touch position for the preset reference time Td. In this case, the label gradually disappears over time. In particular, when the disappearance time of the sign is set to the preset reference time Td, the user can estimate the retention time of the virtual mode through this.

Touch screen device

The present invention discloses a touch screen device for implementing the method.

10 is a diagram illustrating a touch screen device of the present invention.

A controller 610 for performing a first command or a second command based on a change in rotation angle; And a display unit 620 that is controlled by the controller 610, displays a mark at the virtual touch position, and displays an object on which the command is performed.

As an example of the touch screen, a resistive method, a capacitive method, a surface acoustic wave (SAW) method, or an IR (infrared) method may be used. The touch screen includes a display unit 620 and a touch sensor unit 600 mounted on the display unit 620.

The display unit 620 displays a cover and an object. The display unit 620 is controlled by the controller 610. The display unit 620 may be, for example, a liquid crystal display (LCD) or an organic light emitting display (OLED). An object refers to a unit in which image processing (eg, displacement and deformation of an image) can be performed. The object may be, for example, a desktop, an icon or a window for an application (eg Word, Excel and internet explorer, etc.). The object is, for example, an image object displayed on the entire area or a partial area of the touch screen.

The controller 610 calculates and generates a virtual touch position corresponding to the touch position of the user when a predetermined touch event occurs. Herein, the virtual touch position means a position at which a cover is displayed on the touch screen as described above, and the cover may have any shape. That is, in one embodiment of the present invention, the marker has the form of a virtual finger, but the present invention is not limited thereto. The virtual touch position is located in an area other than the touch position. For example, the virtual touch position may also move according to the movement of the touch position, wherein the virtual touch position may correspond to point symmetry of the touch position, and a center point of the point symmetry may be a reference point for determining the rotation angle. .

In particular, the controller 610 performs the above two command systems as the virtual touch position is generated. The first is a first command of the object based on distance, the second is a second command based on the angle of rotation and different from the first command. The form applicable to the said 1st and 2nd instruction is as above-mentioned, It abbreviate | omits below.
