Description

Touch screen control method, a touch screen device using the same, and a mobile device comprising the same {Control method and device 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 device including the same. More particularly, a touch screen control method capable of performing various commands in a single hand situation in detail, a touch screen using the same An apparatus, and a mobile 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 technology, an interaction method based on a gesture of a single (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. There is a considerable amount of resources consumed by formulating a value and comparing it back to a preset equation, and there are many problems with many errors due to similar gestures. In addition, 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 holding a previously input command (for example, a user) in the same mode. In a real mobile environment in which user touch gestures are performed, it is very difficult to distinguish a typical touch gesture from a specific touch gesture that executes a pre-input command, and thus a complex algorithm for distinguishing the touch gesture is used. Particularly in the limited computing conditions of mobile devices, this complex process is triggered at a slow rate, causing a lot of inconvenience for the user.

Furthermore, since the instruction execution unit according to the gesture is fixed, there is a problem that an excessively quick gesture must be performed to actually execute the instruction quickly.

Accordingly, an object of the present invention is to provide a new concept touch screen control method capable of effectively performing a command even in a one-hand situation.

Another object of the present invention is to provide a touch screen control method capable of performing various commands in detail even in a one-handed situation.

In the touch screen control method and apparatus of the present invention, the user can intuitively control the degree of a command performed by the user dragging the touch screen by changing a size of an area on the touch screen corresponding to the command, that is, the size of the control bar. Can be. In addition, since the user can easily set the execution amount of the command performed by the gesture, the execution amount of the command can be adjusted without changing the gesture speed. Furthermore, since the exemplary embodiment of the present invention using a circular control bar uses a circular form without the limitation of the touch screen size, the limit of command execution according to the gesture is eliminated, and the amount of change of the rotation value is proportional to the size of the control bar. As a result, the command execution amount can be adjusted in a fast and accurate continuous manner. In addition, the present invention can effectively perform commands such as zooming in (zoom-in) and zooming out (zoom-out) through a gesture that generates a distance or a rotation angle even in a one-hand situation. However, the present invention solves the problem of the prior art by distinguishing the division of the touch movement through the generation of an area having a predetermined size on the touch screen.

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.

According to the present invention, when a user touch on a touch screen satisfies a predetermined condition, an area having a predetermined size centered on the touch position of the predetermined condition is generated and displayed. Herein, the region refers to a boundary region where a kind of different touch command is performed, and a command performed according to a first drag from the inside of the area and a second drag from the outside is different.

1A and 1B illustrate a touch screen control method according to an exemplary embodiment of the present invention.

Referring to FIG. 1A, in an embodiment of the present invention, the area is represented by a circular shape 120 centered on a touch location (first touch location 110) satisfying a predetermined event condition. The generation conditions of the region may be any touch condition as long as it is distinguished from a normal touch such as a same point touch for a predetermined time, a double touch, a touch over a predetermined pressure, and the like. Switch to a touch command mode that is distinct from a normal touch command such as selecting. In addition, a circular control bar 130 having a predetermined thickness is generated and displayed at an outer boundary of the circular area around the first touch position. The circular control bar provides a path that is infinitely repeated when the user drags a gesture, especially a rotation gesture, and furthermore, since the size is changed according to the dragging shape, various effects can be generated through such a size change. .

The present invention provides a configuration including a plurality of the control bar to perform more commands, which is shown in Figure 1b.

Referring to FIG. 1B, a plurality of control bars are formed outside an area centered on an initial touch point (first touch position 110), and the control bars are spaced at predetermined intervals having different diameters. In this case, each of the control bars corresponds to a separate command menu, and the touched menu is selected as the user touches one of them, and then the selected command is performed.

According to the present invention, after a circular control area (or a circular control bar) is generated and displayed, a first command and / or the first command according to a change in distance from the first touch position generated by the user dragging is generated. The second command is performed according to the rotation angle around the touch position. Hereinafter, this will be described in more detail with reference to the accompanying drawings.

Referring to FIG. 2, after touching a point 140 of a circular control bar formed at an outer area of the circular area, in particular, an outer boundary of a circle, drag from one point 140 to another point 150. In this case, the distance between the first touch position 110 inside the circle and the dragged touch points 140 and 150 becomes long. At this time, the present invention executes the first command according to the distance change.

For example, when the distance is longer when the first command is a zoom command, the screen is enlarged based on the first touch position 110, and when the distance is shortened, the first touch position 110 is referred to. The reduction command of the screen is performed. However, in addition to the zoom command, various commands may be performed based on a change in distance from the first touch position, and any command as long as the distance is a variable is within the scope of the present invention.

According to the present invention, the area or the control bar is displayed in the form of a radius of the distance between the drag touch point and the first touch position in order to make the distance change more intuitive to the user. Therefore, when the distance from the first touch position is increased by dragging, the size of the area and the control bar increases. In particular, the present invention, in addition to helping the user intuitively understand the size of the area and the control bar (more specifically, the radius change), the command execution amount, in particular the command execution amount according to the rotation angle, It explains in detail.

Referring to FIG. 3, after touching one point 140 of a circular bar formed at an outer region of the circular region, in particular, an outer boundary of a circle, dragging from one point 140 to another one point 160. In this case, a rotation angle θ of a predetermined angle occurs based on the first touch position 110. Another command mode of the present invention is to perform a command (hereinafter referred to as a second command) according to the rotation angle. In particular, in the present invention, the second command may be performed together with the first command based on the distance change.

Various embodiments are possible with the first command and the second command, for example, changing image information such as zoom-in, zoom-out of a screen, yin and yang of a screen, contrast, etc., change of sound volume and selection movement of a data list. Etc. are possible.

The following describes an embodiment in which a zoom-in command for enlarging a specific area of a screen is taken as an example.

4A and 4B are diagrams illustrating an embodiment of zooming in a screen by a second command.

Referring to FIG. 4A, a user touches a specific point (first touch position) 410 of a screen according to a predetermined condition, and thus a circular area 420 based on the first touch position 410 is set. In particular, a circular control bar 430 is generated at the outer boundary of the region. As described above, the control bar refers to a command execution region where a user makes a predetermined gesture after touching, and in the embodiment of the present invention, the control bar is formed outside the circular region. Referring to FIG. 4B, when the user touches and selects a point 440 of the circular control bar and rotates clockwise, a zoom-in command based on the first touch position 410 is performed.

5A and 5B are diagrams illustrating an embodiment of zooming in a screen by a first command.

Referring to FIG. 5A, when a user touches a specific point (first touch location) 510 of a screen according to a predetermined condition, a circular area based on the first touch location is set, and a circular area is formed at an outer boundary of the area. Control bar is formed.

Referring to FIG. 5B, a drag is made from one point 540 of the control bar, and the distance between the first touch point and the touch point 550 after the drag is longer by the drag. Accordingly, the screen may be enlarged using the length change ratio, in particular, the screen may be enlarged based on the first touch position 510. At this time, the control bar 530 is also enlarged by dragging to help more intuitive understanding.

The present invention discloses the following configuration, focusing on the fact that the center point of the control bar, that is, the center point of the zoom command can also be changed when the first touch position is moved.

6 is a view for explaining an example of movement of a control bar according to an embodiment of the present invention.

Referring to FIG. 6, according to the present invention, a control bar 620 having an area 610 of a predetermined size is generated therein, and the generation conditions and functions of the control bar 620 are the same as described above. do.

Referring to FIG. 6, a user touches a point 630 in the area 610 and drags it to another outside point 640, wherein the area 610 and the control bar 620 outside the area are moved. Is moved, and as a result, another reference point, that is, the first touch position is set.

As described above, the present invention distinguishes the inside and the outside of the region so that the movement of the control bar when the drag start point is inside the region and performs various commands based on the gesture when the drag start point is outside, particularly inside the control bar region. do.

The present invention discloses a configuration of adjusting a command execution degree according to a unit rotation angle when performing a command by a rotation gesture, that is, a second command. Through the above configuration, the user can adjust the fast command execution through the faster rotation angle change or the slow and fine command execution through the slower rotation angle change.

7A and 7B are diagrams illustrating command execution by a rotation gesture according to an embodiment of the present invention.

Referring to FIG. 7A, after an area having a predetermined size is generated and displayed, the user drags the rotation angle θ1 by dragging from one point 720a to another point 720b in the control bar 710 formed at the outer boundary of the area. And a second command corresponding to the rotation angle, for example, zoom-in or zoom-out, increase or decrease of the sound volume, increase or decrease of the brightness of the screen, and the like. However, in this case, in the case of a touch device such as a human finger, which is difficult to accurately touch, precise and precise command execution amount adjustment is impossible, and the present invention changes the size of the control bar formed in the area and the outside of the area to solve this problem. Disclosed is a configuration to make.

FIG. 7B illustrates a case where the size of the area 730 and the control bar 740 outside the area 730 is increased according to an embodiment of the present invention. The change of the control bar size may be performed by dragging out of the area, in particular from one point within the control bar 740, as described above.

FIG. 7C illustrates a rotation angle generation dragging gesture from a point in the control bar of FIG. 7B.

Referring to FIG. 7C, a user makes a dragging gesture from one point 750a in the control bar 740 to another point 750b. At this time, the rotation angle θ2 that occurs when the user drags the same length by the longer circular area, that is, the outer circumferential length of the longer control bar, becomes smaller than in the case of FIG. 7A. Therefore, in order to generate the same rotation angle as that generated in FIG. 7A, the user must take a longer dragging gesture.

The present invention can control the command execution amount according to the gesture by variously setting the rotation angle change for the gesture of the same length in this manner (which is achieved by adjusting the size of the circular control bar). In other words, in the present invention, the amount of execution of the second command according to the rotation angle change may be adjusted according to the distance between the first touch position and the dragging point (which corresponds to the radius of the control bar). For example, when a fine command such as a fine increase in volume or a fine zoom-in or zoom-out of a screen is to be performed, the change of the rotation angle may be minimized by increasing the size of the control bar. Conversely, if you want to increase the volume, zoom in on the screen, zoom out, etc., you can effectively achieve this by resizing the control bar.

Hereinafter, a touch screen control method according to the present invention will be described with reference to the drawings.

8 is a flowchart illustrating a touch screen control method according to an embodiment of the present invention.

Referring to FIG. 8, the touch screen control method according to the present invention determines whether the detected touch satisfies a predetermined touch event condition. If the predetermined touch event condition is not satisfied, the normal touch command mode for panning an object is performed. In this case, even if a rotation gesture or the like occurs, a separate command based on this is not performed. However, when a predetermined touch event condition is satisfied, an initial touch position that satisfies the event condition, that is, an area having a predetermined distance from the first touch position is displayed and generated. Accordingly, a separate command mode according to the rotation gesture, the distance change gesture, and the like proceeds. That is, after the area is displayed and generated, the first command or the second command according to the change in the rotation angle with the first touch location is performed according to the change in distance from the first touch location generated by the user drag. The execution of the distinguished commands according to the technical significance of the area, that is, dragging from within the area (first drag) and dragging outside the area (second drag) is as described above, and the control bar is located at the outer boundary of the area. More specifically, the circular control bar can be generated as described above.

In addition, the first or second command may be a zoom command such as zoom-in, zoom-out, or the like, wherein the zoom command is performed around a first touch position (ie, a center point of the control bar) in the area, The present invention can freely set and change a target screen of a zoom command by a dragging gesture of moving a control bar.
