Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the configuration of an e-book terminal for performing a bookmark setting method according to an embodiment of the present invention.

Referring to FIG. 1, the e-book terminal includes a memory 100, a display 110, a touch input device 120, and a controller 130.

The memory 100 includes magnetic media such as hard disks, floppy disks and magnetic tapes, optical media such as CD-ROMs and DVDs, and magnetic-optical media such as floptical disks. The storage medium may be implemented as a storage medium such as a magneto-optical media, a ROM, a RAM, and a flash memory.

The memory 100 stores a program for managing and displaying e-book contents (hereinafter, referred to as an “e-book application”) and various reference data for the operation of the controller 130. In particular, the memory 100 stores e-book content for the e-book application, and the e-book content includes a plurality of page-specific content and bookmark setting information.

The display unit 110 provides a plurality of screens for data display, displays content requested for display by the e-book application on a screen, and expresses an appropriate graphic requested by the controller 130.

The touch input device 120 may be implemented as a touch sensor using a material such as a general touch screen, force sensing resistor (FSR) or quantum tuning composite (QTC), or a material whose resistance is changed by pressure or force, or by pressure or force. It can be implemented as a circuit for detecting an electrical change according to the deformation of the outer shape of the touch sensor.

The touch input device 120 may be implemented in the form of a touch pad or a multi touch pad. The touch input device 120 converts a detected user's hand touch or pen touch into an electrical signal and transmits the electrical signal to the controller 130.

The structural arrangement between the display 110 and the touch input device 120 may be performed as illustrated in FIGS. 2A to 2C.

2A illustrates a case in which the touch input device 200 is installed on the display 210. The touch input device 200 directly detects a user's hand touch or pen touch. This corresponds to a typical touch screen implementation method, and the touch input device 220 is made of a transparent material so that a user can see the screen of the display 210.

2B illustrates a case in which the touch input device 230 and the support plate 240 are installed below the display unit 220.

The touch input device 230 may detect the user's finger 10 through the display unit 220 as shown in FIG. 2C. In other words, when the user touches the display unit 220 with a finger 10, the force or pressure caused by the touch deforms the display unit 220, and the deformation is placed below the display unit 220. Induces a deformation 30 of the located touch input device 230. In this way, the touch input device 230 may recognize a user's touch. In addition, the support plate 240 may be positioned below the touch input device 230 to allow the touch input device 230 to recognize only a touch occurring on the upper portion of the display unit 220 and to prevent misrecognition of another touch. have.

2B and 2C, since the touch input device 230 does not cover the display unit 220 and guarantees 100% visibility, the readability of the device, such as the e-book terminal, plays an important role in user satisfaction. Suitable for placement of touch screen.

The controller 130 manages and displays e-book contents stored in the memory 100 by driving the e-book application according to a user's request. The controller 130 includes an initialization unit 131, a touch acquisition unit 133, a gesture recognition unit 135, and a bookmark processing unit 137.

The initialization unit 131 displays a target page selected as the user manipulates the e-book terminal, and defines at least one corner portion or border portion of the target page as a bookmark area. The bookmark area may be used in the recognition process of the gesture recognition unit 135 described later.

The bookmark area may be represented as shown in FIG. 3A or 3B according to an embodiment of the present invention.

Referring to FIG. 3A, it can be seen that the initialization unit 131 defines a bookmark area as a rectangle at four corners of the screen displaying the target page. In order to define the rectangular bookmark area, the initialization unit 131 may determine the position of the rectangle (XLTi, YLTi, i = 1, 2, 3, 4), the width Wi and the height Hi of each rectangle. have.

Referring to FIG. 3B, it can be seen that the initialization unit 131 defines a bookmark area as a quadrant in four corners of the screen displaying the target page. In order to define the bookmark area of the quadrant, the initialization unit 131 may determine the center point position (Oi = (OXi, OYi)) of the quadrant and the radius Ri of the quadrant. Here, W and H refer to the width and height of the screen.

In addition, the initialization unit 131 defines the bookmark area as a border portion (not shown) having a constant different width on the screen displaying the target page by using the width W and the height H of the screen. can do. In addition, the initialization unit 131 may also define the bookmark area as an area (not shown) (hereinafter, referred to as a “folding area” for convenience) displayed as a folded part to express the bookmark on the screen.

The touch acquirer 133 acquires location information of a touch recognized by the user through the touch input device 120. In other words, the touch acquisition unit 133 may be equipped with touch recognition software to acquire location information of a touch recognized by the touch input device 230 through the touch recognition software, and transmit the location information to the gesture recognition unit 135. do.

The gesture recognition unit 135 recognizes the bookmark gesture of the user according to whether the location information of the touch acquired by the touch acquisition unit 133 is included in a bookmark area.

In other words, the gesture recognition unit 135 determines whether the location information of the touch is included in the bookmark area, and as a result of the determination, when the location information is included in the bookmark area, Recognize a predetermined bookmark gesture based on the location information.

The gesture recognizer 135 may include an effective touch recognizer 135a and a gesture determiner 135b.

The effective touch recognition unit 135a recognizes an effective touch located in the bookmark area based on location information of the user's touch or previous / post touch.

In particular, when the initialization unit 131 defines the bookmark area as a rectangle at the four corners of the screen, the effective touch recognition unit 135a has an i-th position of the touch through a condition as shown in Equation 1 below. Whether the touch is the valid touch may be determined by determining whether the bookmark is included in the bookmark area Bi.

[ Equation  One]

IF (XLTi <XT) AND (XT <XLTi + Wi) AND (YLTi <YT) and (YLTi <YT + Hi) THEN PT belongs to Bi

OTHERWISE PT does not belong to Bi

In addition, when the initialization unit 131 defines the bookmark area as quadrants at the four corners of the screen, the effective touch recognition unit 135a may determine the position of the touch (PT =) under the condition as shown in Equation 2 below. It may be determined whether (XT, YT) belongs to the bookmark area B'i to recognize whether the touch is an effective touch.

[ Equation  2]

IF (XT-OXi) * (XT-OXi) + (YT-OYi) * (YT-OYi) <Ri * Ri THEN PT belongs to Bi

OTHERWISE PT does not belong to Bi

IF sqrt {(XT-OXi) * (XT-OXi) + (YT-OYi) * (YT-OYi)} <Ri THEN PT belongs to Bi

OTHERWISE PT does not belong to Bi

Similarly, when the initialization unit 131 defines the border area or the folded area of the screen as the bookmark area, the effective touch recognition unit 135a uses a condition corresponding to the border area and a condition corresponding to the folded area. It may be recognized whether the touch is the effective touch.

When the valid touch is recognized by the valid touch recognizer 135a, the gesture determiner 135b may input one or more of a valid touch of more than a reference number of times, a touch hold of more than a reference holding time, and a drag of more than a reference length. It determines whether or not the bookmark gesture occurs. The gesture determination unit 135b then displays an appropriate graphic such that the target page is folded in synchronization with the occurrence of the bookmark gesture.

Here, the bookmark gesture is a specific gesture in which the user touches the screen of the e-book terminal in order to request the setting of the bookmark, which may be described through the example illustrated in FIG. 4.

Referring to FIG. 4, the screen 400 shows that the user has generated an effective touch 401 in the bookmark area. In the case of the screens 410 and 420, the user has generated drags 411 and 412 having a reference length or more within the bookmark area.

The gesture determination unit 135b recognizes a touch or a drag generated on the screens 400, 410, and 420, and determines whether the gesture is one of a touch hold longer than a reference holding time, a drag longer than a reference length, and an effective touch longer than a reference number. Accordingly, it may be determined that the bookmark gesture has occurred.

In other words, the gesture determiner 135b may detect whether the touch is more than a reference number of times (for example, one time) or a touch hold for more than the reference holding time (for example, two seconds) through the screen 400. In the case of the screens 410 and 420, the touch may sense a drag more than a reference length (eg, a length value of 4 or more). When the detection is successful, the gesture determination unit 135b determines that the bookmark gesture has occurred and recognizes that the bookmark gesture has occurred.

In particular, the gesture determination unit 135b may initiate recognition of the bookmark gesture through an algorithm as shown in Equation 3 below.

[ Equation  3]

FOR ALL i (i = 1, 2, 3, 4), IF PT belongs to Bi THEN SET RECOGNITION_MODE TO GESTURE_BOOKMARKING

In this case, the RECOGNITION_MODE means the recognition mode and means the GESTURE_BOOKMARKING bookmark gesture recognition mode.

In addition, the gesture determination unit 135b may drag the user to move an object (hand or pen) in contact with the touch input device 120 in order to generate the touch. Can be judged by comparison.

In other words, when the distance between the position of the current touch and the position of the previous touch is greater than a predetermined threshold, the gesture determination unit 135b may determine that the bookmark gesture is dragged. This may be implemented through Equation 4 below.

[ Equation  4]

IF SQRT ((XT (n)-XT (n-1)) * (XT (n)-XT (n-1)) + (YT (n)-YT (n-1)) * (YT (n) -YT (n-1)))> TH_D THEN

TOUCH_DRAG is generated.

The location information of the current touch is PT (n) = (XT (n), YT (n)), and the location information of the previous touch is PT (n-1) = (XT (n-1), YT (n). Assuming that the drag is greater than the threshold value TH_D, it is recognized that the dragging of the bookmark gesture occurs. Here, SQRT () means a square root function.

When the bookmark gesture is recognized by the gesture recognition unit 135, the bookmark processing unit 137 determines and sets a bookmark for the currently displayed target page.

In addition, as the bookmark gesture is recognized, the bookmark processor 137 may automatically set the target page as a bookmark or provide a separate confirmation window (shown in FIG. 5) to receive a user's selection.

Referring to FIG. 5, as the bookmark gesture is recognized, the bookmark processor 137 pops up a confirmation window 510 on the screen 500 on which the target page is displayed. Accordingly, the user performs a touch (eg, an effective touch of more than a reference number of times, a touch hold of more than a reference holding time, and a drag of more than a reference length) on the screen 500, and then pops up a screen window ( In operation 510, it may be determined whether a bookmark of the target page is set.

6 shows a configuration of an e-book terminal for performing a bookmark setting method according to another embodiment of the present invention.

In the case of FIG. 6, the e-book terminal recognizes the bookmark gesture like the e-book terminal of FIG. 5, and further sets a bookmark of the target page by further recognizing a bookmark determination gesture for determining a bookmark from the user. Accordingly, the e-book terminal of FIG. 6 may have a configuration other than the control unit 630 (memory 600, the display unit 610, and the touch input device 620) corresponding to reference numerals 100, 110, of the e-book terminal of FIG. 5. It may be implemented in the same manner as the configuration of 120).

The controller 630 includes an initialization unit 631, a touch acquisition unit 633, a gesture recognition unit 635, a determination recognition unit 635, and a bookmark processing unit 637. In particular, the initialization unit 631, the touch acquisition unit 633, and the gesture recognition unit 635 may be implemented in the same manner as the configuration of the corresponding reference numerals 131, 133, and 135 of the e-book terminal of FIG. 5.

The determination recognizing unit 636 recognizes the bookmark determination gesture of the user based on the location information of the user's touch or previous / post touch. The bookmark processing unit 637 sets the bookmark of the target page when the bookmark determination gesture is recognized by the determination recognition unit 636.

Here, the bookmark confirmation gesture is a specific gesture that the user touches the screen of the e-book terminal in order to confirm the setting of the bookmark, which can be described through the example illustrated in FIG. 7.

Referring to FIG. 7, the screen 710 shows that the user has generated a touch hold 712 longer than the reference holding time. In the screen 720, the user requests the setting of the bookmark. After generating the first valid touch 721, the second valid touch 722 is further generated to confirm the bookmark. In the case of the screens 730 and 740, the user generated the drags 732 and 742 of the reference length or longer after generating the first effective touches 731 and 741, and in the case of the screen 750, After the user generates the first drag 751 to request the bookmark, the second drag 752 is further generated to confirm the bookmark.

The determination recognizing unit 636 recognizes a touch or drag generated by the user based on the location information of the user's touch or previous / post touch, and the recognized touch or drag has a touch hold 712 longer than a reference holding time. ), The occurrence of the bookmark confirmation gesture may be determined according to one of the drags 732, 742, and 752 of the reference length or more and the effective touch 722 of the reference number of times or more.

Accordingly, the determination recognizing unit 636 may detect the touch hold 712 of the reference holding time or more through the case of the screen 710, and the effective touch 722 of the reference number of times or more through the case of the screen 720. The touch screen 730, 740, and 750 may detect drags 732, 742, and 752 having a reference length or more.

In addition, the control unit 630 may further include a pressure obtaining unit (not shown) that obtains the pressure information on the touch or a touch occurring thereafter. In this case, the determination recognizing unit 636 may determine whether the bookmark determination gesture is generated according to whether the pressure information acquired by the pressure obtaining unit is greater than or equal to a reference value.

In the case of FIG. 7, the operation of the determination recognizer 636 when the touch input device 620 is implemented as a single touch pad has been described. However, the touch input device 620 may be implemented as a multi-touch pad capable of recognizing multi-touch occurring at the same time. In this case, the operation of the determination recognizer 636 may be described with reference to FIGS. 8A to 8C. .

Referring to FIG. 8A, it can be seen that the user has generated the first touches 801 and 801 ′ and the second touches 802 and 802 ′ on the screen 800. 8B and 8C, while the user generates the first touches 811, 811 ′, 821 and 821 ′ on the screens 810 and 820, the second touches 812, 812 ′, 822 and 822. You can see that drag is generated through ').

That is, the determination recognition unit 636 may recognize whether the user's touch is a bookmark determination gesture based on the location information of the second touches 802, 802 ′, 812, 812 ′, 822, and 822 ′.

Further, the determination recognizing unit 636 determines the recognition and the generation of the bookmark determination gesture according to whether the position information of the second touches 802, 802 ′, 812, 812 ′, 822, 822 ′ is included in the folding area. Can be. In this case, as shown in FIG. 8C, the user performs a gesture of touching along the peripheral area of the line 840 where the paper is displayed as folded (ie, the folded area) (hereinafter, referred to as a “stroke gesture” for convenience). Can be recognized.

9 illustrates the folded region 900 for recognizing the stroke gesture. Referring to FIG. 9, the parameters required for describing the stroke gesture recognition process may be viewed. In this case, since the folding area 900 may be almost impossible for the user to accurately touch the folding line 910 of the bookmark, the folding area 900 may further include an appropriate area based on the folding line 910. Therefore, the folded region 900 may be set to a region where the shortest distance is A from the folding line 910.

When the user touches and drags from the starting point B in the folding area 900 to the end point C, the determination recognizing unit 636 indicates that the touch is a drag of the reference length D or more, and the folding area ( And determining that the bookmark determination gesture has occurred.

In addition, the folded area 900 may exist at a plurality of corners on the screen on which the target data is displayed. If the k-th touch position is PT (k) = (xk, yk), the fold line 910 of the bookmark can be expressed by the formula ax + by + c. Here, a, b, and c are parameters determined according to the type of bookmark.

The distance d (k) between the fold line 910 and the k-th touch position may be calculated by Equation 5 below.

[ Equation  5]

In addition, the path LPT of the touch position from the moment k = 0 to N may be expressed by Equation 6 below. Here, PT (k) is the second touch position at the kth moment, and d (a, b) is the distance between the points a and b.

[ Equation  6]

LPT = d (PT (1), PT (0)) + d (PT (2), PT (1)) + ... + d (PT (N), PT (N-1))

The stroke gesture recognition method as described above may be used in a process in which the gesture recognition unit 135 or 635 determines a bookmark gesture, or in a process in which the determination recognition unit 636 determines a bookmark determination gesture. In addition, when the touch input device 620 is implemented as the multi-touch pad, it may be recognized whether the stroke gesture is generated with respect to the second touch.

10 shows a bookmark setting method according to another embodiment of the present invention.

Referring to FIG. 10, in operation 1000, a touch of a user is recognized to acquire location information of the touch.

Step 1010 recognizes the bookmark gesture of the user according to whether the obtained location information is included in the bookmark area. In addition, step 1010 displays a graphic of folding the target page according to the recognized bookmark gesture.

The screen touch of the user may be described with reference to FIG. 11.

Referring to FIG. 11, the user touches the upper right corner of the target page and drags diagonally through the screens 430 to 460. Accordingly, operation 1000 may be performed to obtain location information of the touch through the screen 430, and operation 1010 may recognize the bookmark gesture based on location information of the touch.

The recognition process of the bookmark gesture may include a plurality of steps illustrated in FIG. 12.

Referring to FIG. 12, when the target page is displayed on the screen 430, one or more corner portions or border portions of the target page are defined as the bookmark area.

Step 1021 determines whether the touch or the previous / post touch is an effective touch located within the bookmark area or the folded area of the bookmark, based on the location information of the touch or the previous / post touch. In particular, step 1021 may determine through the screen 430 that the user's touch is an effective touch.

In step 1022, if it is determined by step 1021 that the touch or the previous / post touch is the valid touch, one or more of a valid touch of at least a reference number of times, a touch hold of at least a reference holding time, and a drag of at least a reference length are inputted. Judge whether or not. In particular, step 1022 may determine that the touch input has a drag of a reference length or more through the screens 440 and 450.

Step 1023 recognizes that the bookmark gesture has occurred when it is determined by step 1022 that one or more of a valid touch of at least a reference number of times, a touch hold of at least a reference holding time, and a drag of at least a reference length are input.

In operation 1020, the bookmark for the currently displayed target page is determined.

In this case, step 1020 may display a separate confirmation window as shown in the screen 460, so that the user can be selected whether or not the bookmark is confirmed. In another case, step 1020 may automatically select whether to confirm the bookmark based on the additionally recognized touch.

In the latter step 1020 may include a number of steps shown in FIG. 13.

Referring to FIG. 13, in operation 1031, a bookmark determination gesture of the user may be recognized based on location information of the touch or previous / post touch. In order to recognize the bookmark confirmation gesture, step 1032 may include multiple steps of FIG. 14 or FIG. 15.

Referring to FIG. 14, step 1031a determines whether the touch or the previous / post touch is maintained for more than a reference time. Step 1032b determines that the bookmark determination gesture has occurred when it is determined by step 1031a that the touch or the previous / post touch has been maintained for more than a reference time.

In addition, the step 1031a may determine whether the touch or the before / after touch is one of an effective touch of a reference number of times or more, a touch hold of a reference holding time, and a drag of a reference length or more.

Referring to FIG. 15, step 1031c acquires pressure information on the touch or a touch that occurs afterwards. Step 1031d determines whether the pressure information obtained by step 1031c is greater than or equal to the reference value. If it is determined in step 1031d that the pressure information is equal to or greater than the reference value, step 1031e determines that the bookmark determination gesture has occurred.

Step 1032 sets the bookmark for the target page.

As a result, the user may touch, drag, hold, stroke, or touch a side of the target page (for example, one side edge or one side border) as shown on the screens 400, 410, and 420. By generating a touch or the like, a bookmark setting request for the target page can be made intuitively and easily.

Similarly, the user may display the effective touch more than a reference number of times, the drag including the bookmark area, the touch hold in the bookmark area, the stroke gesture in the folded area, as shown on the screens 710, 720, 730, 740, and 750. By generating an effective touch with a predetermined pressure, a continuous drag including the bookmark area, the bookmark setting for the target page can be made more concise.

Further, in operation 1031, when the input of the touch supports multi-touch at the same time, the bookmark determination gesture may be recognized after the touch or based on the location information of the multi-touches.

In this case, as shown in the screens 800, 810, and 820, the user generates a first touch, and then touches the touch area in the bookmark area, the touch hold in the bookmark area, the folded touch more than a reference number of times. The bookmark setting for the target page can be variously commanded by generating a stroke gesture, an effective touch having a predetermined pressure, and a continuous drag including the bookmark area with the second touch.

Methods according to an embodiment of the present invention may be implemented in the form of program instructions that can be executed by various computer means and recorded in a computer readable medium. The computer readable medium may include program instructions, data files, data structures, etc. alone or in combination. Program instructions recorded on the media may be those specially designed and constructed for the purposes of the present invention, or they may be of the kind well-known and available to those having skill in the computer software arts.

For example, although the gesture recognition unit 135 is implemented to recognize the bookmark gesture for setting the bookmark of the target page according to whether the location information of the touch is included in the bookmark area, the present invention is not limited thereto. no.

That is, when releasing the bookmark setting, the gesture recognition unit 135 determines a specific gesture for setting the bookmark releasing of the target page according to whether the location information of the touch is included in the bookmark area (effective touch of more than a reference number of times, the bookmark). A drag including an area, a touch hold in the bookmark area, a stroke gesture in the folded area, an effective touch with a predetermined pressure, and a continuous drag including the bookmark area). In this case, the bookmark processing unit 137 may release and set the bookmark for the target page as the gesture for setting the bookmark release is recognized by the gesture recognition unit 135.
