Description

Method and apparatus for providing a user interface in a device having a touch screen {METHOD AND APPARATUS FOR PROVIDING USER INTERFACE IN A DEVICE EQUIPED WITH TOUCH SCREEN}

The present invention relates to a method and apparatus for providing a user interface in a device having a touch screen, and more particularly, to a method and an apparatus for displaying a touched area of a user in a device having a touch screen.

Today, most electronic devices implement various user interface (UI) techniques for inputting information from or providing information to a user.

The user interface technique has been developed for the purpose of allowing a user to use functions provided by the electronic device more conveniently. One of the increasing user interfaces for this purpose is a user interface technique using a touch screen (or touch panel).

Due to its convenience, the user interface technique using the touch screen has been widely applied to personal digital assistants (PDAs), smart phones, cellular phones, and Internet phones. In addition, in the above products, the user interface technique using the touch screen is widely used when performing functions such as phone book, scheduler, short message, personal information management, Internet access, and electronic dictionary.

Typically, the touch screen enters commands or graphic information specified by the user by the position where the stylus pen or finger is pressed. The touch screen may be implemented through a character recognition function proposed according to the development of pattern recognition technology and software supporting the same, and through the input means naturally used such as a pen or a hand, information desired by a user It is easy to input and use is increasing.

In particular, the touch screen has been evaluated as the most ideal input method under the Graphic User Interface (GUI) environment because the user can directly perform a desired task while viewing the screen, and anyone can easily operate the touch screen.

In recent years, since the Internet environment, which is implemented in a personal computer (PC), is implemented in a portable terminal such as full browsing, a user's touch event should be generated at an accurate point. In addition, the user needs to check whether his or her touch event is made at a desired point.

However, when the user performed a touch event on the touch screen, it was difficult to confirm that the user himself touched the location correctly on the touch screen. In particular, when the user touches the touch screen with a finger instead of the stylus pen, it is not easy to select a point on the touch screen because the finger is dull compared to the stylus pen.

Furthermore, when the touch screen is provided in a small device such as a portable terminal, it is more difficult to accurately select the desired graphic element among the graphic elements displayed on the touch screen.

The present invention provides an apparatus and method for displaying a touched area on a touch screen in a device having a touch screen.

The present invention provides an apparatus and method for maintaining a graphic display on a region where a touch event occurs for a predetermined time after a user's touch event occurs in a device having a touch screen.

A method for providing a user interface in a device having a touch screen according to the present invention includes a recognition step of recognizing a touch area in which a touch is generated by a user on the touch screen, and an area larger than the recognized touch area by a predetermined size. And a graphic display step of displaying the graphic.

In an apparatus having a touch screen according to the present invention, a device for providing a user interface includes a sensing unit that recognizes a touch area in which a touch is generated by a user on the touch screen, and an area that is larger than the recognized touch area by a predetermined size. And a controller for controlling the touch screen to display a graphic.

According to the present invention, since the user can visually recognize his or her touch area in the device having the touch screen, it is easy to check the area touched by the user on the touch screen.

Further, according to the present invention, after the user generates a touch event on the touch screen, the user can visually check which part he or she selected, thereby improving the accuracy of the touch event.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, only parts necessary for understanding the operation according to the embodiment of the present invention will be described, and the description of other parts will be omitted so as not to disturb the gist of the present invention.

It should be interpreted as meaning and concept corresponding to the technical idea of the present invention based on the principle that it can. Therefore, the embodiments described in the present specification and the configuration shown in the drawings are only the most preferred embodiments of the present invention, and do not represent all of the technical ideas of the present invention, and various alternatives may be substituted at the time of the present application. It should be understood that there may be equivalents and variations.

The present invention relates to a method and apparatus for displaying a region where a touch event occurs to a user through a display means when a touch event is generated by a user's touch in a touch screen device having a touch screen.

In an embodiment of the present invention, the touch event may be largely classified into a tap event and a flick event. The tap event represents an action such as a user tapping (shortly) the touch area of the touch screen. The flick event represents an action such as a user bounces off a touch area of the touch screen. In an embodiment of the present invention, the tap and flick events may be generated using a touch mechanism such as a finger or a stylus pen. In addition, the touch screen device with a touch screen proposed by the present invention may be a portable terminal. A touch screen is provided such as a PDA, a smart phone, an automatic teller machine (ATM), and the like, and can be commonly applied to devices receiving a touch event from a user.

1 is a block diagram of an apparatus 100 having a touch screen according to an embodiment of the present invention.

In general, there are various touch recognition methods applied to the touch panel, but mainly resistive, capacitive, infrared, and acoustic wave (SAW) methods This is mainstream.

Typically, the capacitive method recognizes a user's touch as a change in conductive film current flow by static electricity generated in a human body. In addition, the resistive film method recognizes the user's touch by recognizing the pressure by applying pressure by pressing the touch screen with a user's finger or a stylus pen.

In the present invention, the resistive touch panel technology of the above four methods will be described as an example, but the same may be applied to other methods.

In FIG. 1, when a touch event occurs due to a user's finger or a stylus pen, the touch panel 102 transmits a potential difference of a region where the touch event occurs to the sensing unit 104.

The detector 104 detects a touch event generated by the user's contact on the touch panel 102, that is, a potential difference, and determines a region where the touch event occurs. Hereinafter, in the present specification, an area where a touch event occurs in the touch panel 102 will be referred to as a 'touch event generation area' or 'touch area'. In addition, the detection unit 104 checks whether the touch event from the user has ended, and informs the control unit 106 of the inspection result. That is, the detector 104 recognizes the touch area where the touch is generated by the user and informs the controller 106 of the result.

The display unit 108 configures and displays the screen according to the screen configuration information transmitted from the control unit 106. The display unit 108 may be a liquid crystal display (LCD). In the present specification, the touch screen is used to mean the touch panel 102 and the display unit 108.

The controller 106 controls the display unit 108 to display an area of a predetermined size or more than the touch event occurrence area determined by the detector 104 according to an exemplary embodiment of the present invention. A detailed description thereof will be described with reference to FIG. 2.

2 illustrates a graphic display on a touch screen larger than a touch event occurrence area by a predetermined size or more. Referring to FIG.

Reference numeral 200 shows an example in which the display unit 108 graphically displays the edge of a predetermined thickness larger than the touch event generation region 202 under the control of the controller 106. In addition, reference numeral 202 illustrates an example in which the display unit 108 displays a predetermined macro graphic 214 so that the user can recognize the predetermined point at the outside of the touch event generation area 212 under the control of the control unit 106. . In reference numeral 200, a separate graphic display is provided on the edge of the touch event generating region 202 to distinguish it from the touch event generating region 202 as shown by reference numeral 204.

Reference numeral 210 of FIG. 2 graphically displays dots at predetermined points on the edge to identify the edge of the touch event occurrence area 212. In the reference numeral 210 of FIG. 2, the display unit 108 displays the graphic by four spots on the outside of the touch area generated by the user under the control of the controller 106. However, this is only an exemplary embodiment and may display a graphic on the outside of the touch area with at least one dot.

Although not illustrated by the drawings, a display method for confirming a touch event occurrence region may be variously implemented. For example, the concentric circles centered on the touch event generating area may be expressed in a form of gradually expanding or in a form in which a graphic display part is flickered.

In addition, when the touch event of the user is terminated, the controller 106 controls the display unit 108 so that the graphic display does not disappear for a predetermined time. The description thereof will be described with reference to FIG. 3.

FIG. 3 illustrates that the touch event generated by the user is ended according to an exemplary embodiment of the present invention so that the controller 106 controls the display unit 108 to graphically display the touch event occurrence region and gradually fades out for a predetermined time. Is showing.

In FIG. 3, reference numeral 300 illustrates that the touch event is terminated so that the controller 106 controls the display unit 108 to graphically display the touch area. In this case, the touch event is terminated and the display unit 108 may display only the touch event generating area or the graphic display part outside the touch event generating area. That is, the controller 106 controls the display unit 108 to extinguish the graphic display of the touch area generated by the user or the area larger than the touch area by a predetermined size for a predetermined time and then extinguish it.

When the controller 106 confirms that the touch event is finished, the controller 106 controls the display unit 108 to graphically display a region where the touch event occurs as shown by reference numeral 300 of FIG. 3. Then, as shown by reference numerals 310 to 330, the graphic display 300a of the touch event generation area is faded out for a predetermined time. Portions 310a, 320a, and 330a indicated by dotted lines at 310, 320, and 330 indicate the first touch event generation area generated by the user. In addition, after the touch event ends, the controller 106 gradually reduces the size of the graphic display of the recognized touch area or the graphic display of the area larger than the touch area by a predetermined size, so that a predetermined time elapses. The display unit 108 may be controlled such that the graphic display disappears.

As shown in FIG. 3, in the embodiment of the present invention, when the touch event from the user ends, when the area where the touch event occurs is displayed graphically, only the area where the actual touch event occurs may be displayed graphically, or the actual touch. The graphic display may be performed by including an area where an event occurs and an outline of the touch area illustrated in FIG. 2.

4 is a flowchart illustrating a method for graphically displaying a touch event area by the touch screen device 100 according to a first embodiment of the present invention.

The touch screen device 100 checks whether a touch event has occurred in step S400. Whether the touch event occurs in operation S400 may be determined by detecting whether a touch from the user occurs on the touch panel 102. When a connection is generated from the user to the touch panel 102, the potential difference of the corresponding region is generated or the amount of current is changed in the touch panel 102. In operation S402, the touch screen apparatus 100 graphically displays an outer area of the touch event generation region (touch region), and checks whether the touch event is terminated in operation S404. If the touch event is terminated as a result of the check in step S404, the touch screen device 100 destroys the graphic displayed on the outside of the touch area in step S406. In operation S408, the touch screen apparatus 100 displays the touch area graphically, and in step S410, gradually removes the graphic display of the touch area as shown in FIG. 3.

5 is a flowchart illustrating a method for graphically displaying a touch event area by the touch screen device 100 according to a second embodiment of the present invention.

In operation S500, the touch screen apparatus 100 checks whether a touch event has occurred. Whether or not a touch event occurs in step S500 may be determined by detecting whether a touch from the user occurs on the touch screen. In operation S502, the touch screen apparatus 100 graphically displays an outer area of the touch event generation region (touch region), and checks whether the touch event has ended in operation S504. If the touch event is terminated as a result of the check in step S504, the touch screen device 100 graphically displays the touch area and the outer periphery of the touch area in step S506, and with reference to FIG. Similarly, the graphic display of the touch area and the touch area gradually disappears.

The method of the present invention as described above may be implemented in a program and stored in a recording medium (CD-ROM, RAM, floppy disk, hard disk, magneto-optical disk, flash memory, etc.) in a computer-readable form. Since this process can be easily carried out by those skilled in the art to which the present invention pertains will not be described in more detail.
