Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.

FIG. 1 is a diagram showing a front view of a video playback control apparatus 100 using contact position information and force according to an embodiment. According to an exemplary embodiment, the user can directly use the gesture input in connection with manipulation of the image content through an additional gesture input that does not conflict with the existing touch pad operation. Thus, cursor position recognition is possible. It can be used as absolute mapping and relative mapping.

According to an exemplary embodiment, playback of image contents and the like can be performed using a touch pad capable of measuring vertical and horizontal forces. In a conventional touch-based remote controller, a GUI (Graphic User Interface) button may be disposed for controlling image contents, and a cursor may be moved to select a button. This is because, when the motion detected on the touch pad is directly connected to the control of the image contents, the cursor control using the touch pad can not be used.

For example, as shown in FIG. 1, a video playback control apparatus 100 according to an exemplary embodiment is a controller structure in the form of a remote controller, and includes a touch pad 110 and four Side pressure sensors 131, 132, 133, and 134 may be installed. For example, the first side pressure sensor 131, the second side pressure sensor 132, the third side pressure sensor 133, and the fourth side pressure sensor 134 may be installed on four sides of the four sides. Also, a lower end pressure sensor 120 capable of measuring a vertical force may be installed under the touch pad.

2 is a diagram showing a side view of a video playback control apparatus 200 using contact position information and force according to an embodiment.

For example, as shown in FIG. 2, the touch pad 210 of the video playback controller 200 according to an exemplary embodiment of the present invention is positioned on the lower end pressure sensor 220, and the lower end of the touch pad and the pressure sensor 220, 231, and 232, may be added. By using such a structure, both the force of pressing the touch pad vertically (hereinafter referred to as a vertical force) and the force of the touch pad being pushed in the lateral direction (hereinafter referred to as a horizontal force) by the frictional force can be measured. In addition, the input by the movement of the contact position of the touch and the touch on the touch pad can be used as it is.

3 is a graph showing the transfer function of horizontal force in a video playback control apparatus using contact position information and force according to an embodiment. According to an exemplary embodiment, when the playback speed is adjusted using the horizontal force applied to the video playback controller, the relationship between the playback speed and the intensity of the playback speed may be displayed.

For example, when the horizontal force is applied in the left or right direction as the transverse direction, the reproduction of the video may be kept in a pause state before the intensity of the horizontal force with respect to the transverse direction exceeds the reproduction speed control threshold value 310 . If the horizontal force for the horizontal direction starts to exceed the reproduction speed control threshold value 310, the reproduction speed may increase proportionally as the horizontal force increases. According to an embodiment, the magnitude of the horizontal force and the proportion of the playback speed can be set by the user, and the playback speed 320 and the magnitude of the horizontal force corresponding to the 1x speed can be shown in the figure.

Here, if the rightward horizontal force is applied, the reproduction speed is adjusted in the reproduction direction of the image, and if the horizontal direction force is applied to the leftward direction, the reproduction speed is adjusted in the reverse direction in which the image is reproduced. If the playback speed reaches the maximum setting speed, the speed may not be adjusted even if a higher force is applied. For example, when the magnitude of the horizontal force is equal to or greater than the maximum horizontal threshold value, the playback speed can be determined as the maximum playback speed set as the maximum setting speed 330. [

6A is a flowchart illustrating a method of controlling video playback using contact position information and force according to an embodiment.

In step 601, a touch can be detected. Here, the touch can be sensed by an electrostatic or a pressure sensitive. According to one embodiment, it may be desirable to use an electrostatic type to distinguish it from the vertical or horizontal forces applied to the touchpad.

In step 602, the pressure can be sensed when the touch is maintained. Here, the pressure may be a vertical force or a horizontal force applied to the touch pad.

Then, in step 603, contact position information of the touch can be collected. According to one embodiment, movement of the touched touch location may be sensed based on pressure.

And in step 604 the processor may generate a playback control command in accordance with the vertical force and contact position information. According to one embodiment, a reproduction control command can be generated in accordance with the movement of the touched position. Specifically, as shown in the state diagram shown in FIG. 6B, A playback operation can be performed.

6B is a state diagram illustrating a video playback control method using contact position information and force according to an embodiment. According to one embodiment, the input state can be classified into three stages according to the magnitude of the force pressing the touch pad of the video player in the vertical direction.

의 가속도를 발생시키는 힘의 크기를 의미하는 단위일 수 있다.When the touch is detected but the intensity of the vertical force is below the first threshold value, the touch state 610 is reached. When the intensity of the vertical force is below the first threshold value, the lightly pressed state 640 is displayed. And a strongly pressed state 670 can be obtained. For example, the first threshold value for the transition of the input state can be set to 4N, and the second threshold value can be set to 8N. Where N is the MKSA (Meter-Kilogram-Second-Ampere) unit of force and is 1

Which is a unit of magnitude of a force that generates acceleration of the vehicle.

In addition, the up and down movement operation and the horizontal movement operation of the touch operation sensed in each input state, and the vertical pressure operation and the horizontal pressure operation during the pressure operation may be as follows.

For example, the up-and-down movement operation may be performed when the touch movement distance from the touch start point, which is the first touch position, is equal to or greater than 5 mm according to an embodiment, and the angle between the line segment indicated by the movement of the contact position and the straight line in the up- -45 to 45 degrees or -135 to 135 degrees.

The horizontal movement operation is, for example, a case where the touch movement distance from the touch start point, which is the first touch position, is a predetermined distance, according to an embodiment, 5 mm or more, and the angle between the line segment indicated by the movement of the contact position and the straight line in the vertical direction Between 45 and 135 degrees or between -45 and-135 degrees.

For example, when the magnitude of the horizontal force cursor derived by the following equation (1) is equal to or greater than the pressure threshold value, the vertical pressure operation is performed such that the angle between the horizontal force cursor vector and the vertical straight line is -45 to 45 degrees, 135 < / RTI > in the longitudinal direction of the touch pad.

For example, when the horizontal force cursor value derived by Equation (1) is equal to or greater than the pressure threshold value, the horizontal pressure operation is performed such that the angle between the horizontal force cursor vector and the vertical straight line is 45 to 135 degrees, The horizontal force may be applied to the horizontal direction of the touch pad between -135 degrees.

In the above Equation 1, force_x and force_y may be positions of the x and y axes of the force cursor. R is the value of the right side pressure sensor, L is the value of the left side pressure sensor, B is the value of the lower side pressure sensor, T is the value of the upper side pressure sensor, R_max is the value L_max is a maximum value obtainable from the left side pressure sensor, B_max is a maximum value obtainable from the lower side pressure sensor, and T_max is a maximum value obtainable from the upper side pressure sensor.

The concrete embodiment of transition from each input state to another input state may appear as follows.

First, if a touch is detected in the non-touch state 600, the touch state 610 can be changed regardless of the magnitude of the vertical force.

If the touch is not detected due to, for example, a hand being dropped in the touched state 610, the user can return to the non-touched state 600. Here, if the upward / downward movement is detected, the menu can be shifted to the moving state 620. If the horizontal movement is detected, the horizontal cursor moving state 630 can be performed. In addition, if no touch is detected in the menu moving state 620 and the horizontal cursor moving state 630, the state may return to the non-touch state 600. [

According to one embodiment, in the menu moving state 620, it is possible to move between the menus arranged in the vertical direction. For example, as shown in FIG. 4, the time line and the playback control button may be arranged in a direction perpendicular to each other. Specifically, between the button operations for performing the operation of the time line and the playback or the pause, the menu movement function can operate when the up-down movement operation is detected in the touched state 610. [

According to one embodiment, the cursor may be moved horizontally in the horizontal cursor moving state 630. [ For example, as shown in FIG. 4, when a horizontal movement operation is detected when a playback control function is performed on a time line, a scene preview corresponding to a cursor position can be performed by moving a timeline cursor. Or if there is a cursor on the reproduction control button, a movement for selecting a reproduction control button such as reproduction, stop, or recall can be performed. Even if the scene preview changes depending on the cursor position, the image actually displayed on the image display unit may not be influenced.

Then, if the magnitude of the sensed vertical force is greater than the first threshold value and less than the second threshold value, the transition to the weakly depressed state 640 may be performed. If the up-down movement operation is detected, the control state transition to the C-D Gain (Control-Display Gain) control state 650 can be performed. If the horizontal movement operation is detected, the transition to the time line movement state 660 can be performed. In addition, when the magnitude of the vertical force detected in the weakly depressed state 640, the CD gain control state 650, and the timeline moving state 660 is equal to or less than the first threshold value, the state may be returned to the touched state 610 .

According to one embodiment, in the C-D gain control state 650, the precision of the operation can be set by adjusting the sensitivity (C-D Gain). For example, more precise operation can be performed by adjusting the degree of precision of the movement of the timeline during the movement of the timeline by the up and down movement operation.

According to one embodiment, in the time line movement state 660, the position being reproduced in the image display unit can be moved through the time line. For example, the time line is moved according to the horizontal movement operation on the touchpad, and the reproduced screen is reproduced in the image display unit while being called to the screen corresponding to the current timeline cursor position.

And if the magnitude of the sensed vertical force is greater than the second threshold value, it may transition to a strongly pressed state 670. [ If the up / down pressure operation is detected, the transition to the timeline enlargement state 680 can be performed. If the horizontal pressure operation is detected, the transition to the regeneration speed adjustment state 690 can be performed. In addition, when the magnitude of the vertical force is less than the second threshold value in the strongly pressed state 670, the timeline extended state 680 and the reproduction speed adjusted state 690, the state can be returned to the weakly pressed state 640.

According to one embodiment, in the timeline enlargement state 680, the timeline can be enlarged or reduced according to the upward / downward pressure operation in the vertical direction. For example, if a horizontal force pushing the touchpad upward is detected, the timeline can be enlarged for a fine preview, or the timeline can be reduced if horizontal force is detected. However, the present invention is not limited to this, and in the opposite case, the horizontal force may be reduced in the downward direction and enlarged in the upward direction.

According to one embodiment, in the reproduction speed control state 690, the reproduction speed can be continuously adjusted according to the transfer function of the horizontal force shown in FIG. 3 and the expression (1). According to another embodiment, the regeneration speed may be adjusted only considering the horizontal force regardless of the vertical force.

According to another embodiment, when the current input state is the touch state 610, there is no change in the image being reproduced, but in the lightly pressed state 640, the image reproduced in the image display unit is temporarily stopped And can return to the touched state 610 and continue playing again.

According to another embodiment, the image is temporarily stopped even when the state is changed to the strongly pressed state 670, and the pause can be maintained when the state changes to the touch state 610 again without any operation. Likewise, playback may resume when transitioning from the paused state to the strongly depressed state 670 and then back to the touched state 610. [
