As used herein, the touch screen is a form of a screen capable of detecting both a direct or proximity touch of a user, and includes both a capacitive and a resistive film. In addition, the user terminal includes any electronic device having a touch screen, such as a mobile phone, a notebook, an e-book, etc., but is preferably a mobile terminal. In addition, the content displayed on the display includes all content, such as an arbitrary picture, a document, etc., which are displayed on the touch screen and can be controlled by the user.

1 is a step diagram of a user terminal control method according to an embodiment of the present invention.

Referring to FIG. 1, the present invention first displays a control area, which is a touch area for controlling content that can be sequentially displayed on a display, on a touch screen around the content (S110). In addition, in an embodiment of the present invention, the content may be a document, a photo, a slide, etc. including a plurality of pages, and the control area is an area for changing the displayed content. Should be. Accordingly, the control area may be displayed around the content, preferably adjacent to the outside of the content. The control area may be displayed in advance around the content displayed on the display, or may be displayed or disappear according to a predetermined event (eg, tilting of the user terminal by a predetermined angle or more).

Thereafter, the content displayed on the display is controlled according to the touch gesture in the control area (S120).

In this case, the controlling of the content according to the touch gesture in the control region (S120) may include generating the control region and the size of the control region according to the direction of the touch gesture following the generation of the control region. And controlling the content according to the size of the adjusted control area. In addition, controlling the content may mean, for example, determining an event of moving a page of the e-book.

The touch gestures may be classified according to touch duration, dragging length, direction, and number of touches. Hereinafter, a content control method according to each touch gesture will be described in detail.

2 to 5 are diagrams illustrating a content control method according to an embodiment of the present invention.

2, a user terminal 210, such as a mobile phone or tablet PC, is shown. The user terminal 210 includes a touch screen display 211, and the content 213 such as an e-book is displayed on the touch screen 211. In the present invention, the content 213 is composed of a plurality, and the plurality of contents (each page of the book in FIG. 2) overlap each other.

Referring to FIG. 3, the control area 300 is displayed around the content 213 according to a predetermined event. In one embodiment of the present invention, the control area 300 may be displayed according to the inclination of the user terminal or may be displayed by pressing or touching a predetermined active button. That is, when the user sequentially converts or searches the contents displayed on the display, the present invention displays the control region 300, which is a separate touch region for controlling contents, on the touch screen around the contents 213. .

Referring to FIG. 4, a user touches a point 301 of the control area 300. In this case, when the one point 301 is touched, the content displayed on the touch screen is determined according to the touch point. In more detail, first, the overall width of the control area 300 corresponds to the total number of contents. Therefore, the content displayed according to the touch point among the entire content is determined according to the ratio of the touch point position to the full width. For example, when the total number of contents is 200, the control area 300 is divided into 200 segments, and the content corresponding to the segment of the touched point may be displayed on the touch screen. In FIG. 4, the number of pages (page 15) determined according to the touch position in the control area is displayed on the touch screen, so that the user can know contents corresponding to his or her touch.

Referring to FIG. 5, the determined content (page 15) is displayed according to the dragging gesture from the touch point 301 to the content area. In the above-described manner of the present invention, the user may receive a feeling of turning a book from the touch-dragging gesture. Furthermore, when only the information of the corresponding content portion (for example, the number of pages) is displayed according to the touch of the control region, the user may search for the desired content portion by touch dragging (low speed) in the control region. When the content is searched, the content may be displayed on the touch screen by a dragging gesture of a predetermined speed or more. If the dragging gesture is less than the predetermined speed, the dragging gesture may be recognized as a touch gesture for content search. Therefore, the dragging gesture that is performed after the determination of the displayed content of the predetermined speed or more is more than the predetermined speed.

Furthermore, the present invention provides a touch screen control method for controlling content according to a touch duration in a control area.

6 to 10 are diagrams illustrating a content control method according to an embodiment of the present invention.

Referring to FIG. 7, the control area 300 is displayed around the content 213 according to a predetermined event. In one embodiment of the present invention, the control area 300 may be displayed according to the inclination of the user terminal or may be displayed by pressing or touching a predetermined active button. That is, when the user sequentially converts or searches the contents displayed on the display, the present invention displays the control region 300, which is a separate touch region for controlling contents, on the touch screen around the contents 213. .

Referring to FIG. 8, a user touches a point 301 of the control area 300. In this case, when the one point 301 is touched, the content corresponding to the touch point is displayed. In more detail, first, the overall width of the control area 300 corresponds to the total number of contents. Therefore, the content displayed according to the touch point among the entire content is determined according to the ratio of the touch point position to the full width. For example, when the total number of contents is 200, the control area 300 is divided into 200 segments, and the content corresponding to the segment of the touched point may be displayed on the touch screen.

Referring to FIG. 9, the touch point 301 is displayed on the touch screen as the touch point 301 is continuously touched, and the contents are sequentially converted to the next content. When the control area 300 is displayed on the right side of the content displayed on the touch screen, as the touch continues, the display content may be converted and moved to the next content, and when the control area 300 is displayed on the left side of the display content, The display content may be automatically converted and moved sequentially to the previous content according to the touch duration.

In FIG. 10, as the desired content (page 15) is displayed on the touch screen, the user releases the touch state or drags or flips a gesture to the content 213 area outside the control area 300. Fix the corresponding automatically converted content.

As such, the present invention displays a separate control area for controlling the content around the content displayed on the touch screen, and controls the displayed content according to the touch gesture in the control area.

Furthermore, the present invention provides a technical configuration in which the touch gesture of the control region may be a reference number in a multi-touch based touch screen, and the conversion unit of the content is determined according to the number of touches simultaneously touching the control region. do.

11 to 14 are diagrams illustrating a user terminal control method according to another embodiment of the present invention.

Referring to FIG. 13, the control area 300 is touched by one input means (for example, a finger). As a result, the display content is converted to the next content (the next page in FIG. 7) and displayed on the touch screen. At this time, unlike the way in which the next content is passed only by the touch, the content may be moved by dragging or flipping after touching, and the content moving unit is determined according to the number of touches in the control area.

Referring to FIG. 14, unlike FIG. 9, the user touches the control area 300 with two fingers. As a result, the conversion unit is determined to be 2, and as a result, each page is converted to the second next page in FIG. As a result, one page is three pages, and two pages are four pages. If the number of multi-touch is four, it is obvious that the page turns by four pages. The display content conversion may be based on dragging or flip gesture after touch, and the display content may be continuously converted according to the dragging length or the touch duration. In this case, the content movement unit is determined according to the number of touches of the control area 300 as described above.

Furthermore, another embodiment of the present invention discloses a method of adjusting the size of the control area 300 that provides the side interface of the touch screen. That is, in a narrow touch screen environment, the control area 300 should have a relatively large size so that a user can easily search and move contents. However, when the control area 300 is displayed only at a fixed ratio with respect to the entire content size, precise control of the control area 300 becomes difficult due to the low resolution of the user's finger. In this case, the user may adjust the size of the control area according to another touch gesture that is distinguished from the touch gesture that controls the content in the control area.

15 and 16 illustrate a control area adjusting method according to an embodiment of the present invention.

Referring to FIG. 15, a user touches two points p1 and p2 of the control area 300, which are distinguished from a single touch that determines display contents of the touch screen described with reference to FIGS. 2 to 5.

Referring to FIG. 16, the size of the control area is enlarged or reduced according to the direction and distance of dragging of multi-touch (this is distinguished from the single touch dragging of FIG. 5 for displaying contents). As described above, the search and movement of content such as an e-book is performed through a separate interface displayed around the content, thereby minimizing the length and number of touch gestures for searching the entire content.

The present invention provides a control device for controlling a user terminal for another object described above.

It may be a normal touch.

Referring to FIG. 20, dragging of type 3 is performed from the touch for pattern recognition. Accordingly, the user terminal according to the present invention detects the dragging pattern on the touch screen, and recognizes that the pattern is three.

Referring to FIG. 21, the e-book page, which is the content displayed on the touch screen, is converted to the third page by the dragging gesture of the third shape (pattern). As described above, the present invention recognizes the pattern of the dragging gesture performed after the touch and determines the page to be actually converted. In addition, a normal touch (for example, a touch for moving a content) and a touch for determining content conversion may be distinguished, and the division may be touch time or touch pressure at the same point.

Hereinafter, the user terminal control apparatus according to the present embodiment will be described.
