1 is a diagram illustrating a structure of a screen motion control apparatus according to an embodiment of the present invention.

According to an embodiment of the present invention, the device 101 may be a smartphone or a smartpad, which can change a screen based on a touch input of a user. Although the device 101 of FIG. 1 is shown on the basis of an embodiment of a smartphone or smart pad, the device 101 may be a display device including a personal computer, a laptop, . The screen motion control apparatus according to one embodiment can be mounted as a part of the device 101. [

Referring to FIG. 1, the screen motion control apparatus according to an exemplary embodiment may operate in conjunction with a screen 102 displaying a screen. The screen 102 may be any one of a liquid crystal display (LCD), a light emitting polymer display (LPD), a plasma display panel (PDP), or a light emitting diode (LED) have. In addition, the screen 102 may include electronic ink.

Referring to FIG. 1, the scroll control apparatus according to an exemplary embodiment may include a sensor unit 103 for detecting a touch input from a user. In response to at least one touch input, the sensor unit 103 can output the coordinates and contact time of each of the touch inputs. The sensor unit 103 can detect a touch input according to any one of a depressurization type, an electrostatic type, an infrared type, and a surface acoustic wave type.

Referring to FIG. 1, the screen motion control apparatus according to one embodiment may include a processor 104 that moves a screen displayed on the screen 102 based on a touch input of a user. The processor 104 may determine a direction in which to move the screen and a distance to move based on the touch input detected by the sensor unit 103. The processor 104 may display an interface on the screen 102 to collect information about movement of the screen from the user. The interface may include a reference direction indicating the direction to move the screen.

When the user touches the reference direction in the interface, the sensor unit 103 can detect the coordinates of the touch input and the contact time of the touch input. Processor 104 may identify the selected reference direction based on the coordinates of the detected touch input. In addition, the processor 104 may determine the distance to move the screen based on the detected contact time. The processor can move the screen based on the identified reference direction and the determined travel distance.

According to one embodiment of the present invention, the processor 104 may be a central processing unit (CPU) or a chipset. The processor 104 may fetch the instruction recording the scroll control method from the internal memory or the external memory. The processor 104 may perform a scrolling control method according to an embodiment based on the fetched instruction.

The scroll control device according to one embodiment may be provided in a stand-alone manner. That is, a screen movement control apparatus including only the screen 102, the sensor unit 103, and the processor 104 may be provided.

2A and 2B are diagrams illustrating a user interface screen output by the screen motion control apparatus according to an embodiment of the present invention. The screen motion control apparatus can output an interface for collecting information on the movement of the screen on the screen along each side of the screen.

The scroll control device may be implemented in a smart phone or a smart pad. In this case, the direction of the screen may be divided into a portrait mode in which long sides of the screen are perpendicular to the ground surface and a landscape mode in which long sides of the screen are horizontal to the ground surface. FIG. 2A is a diagram illustrating a user interface screen output by the screen motion controller in the portrait mode. FIG. FIG. 2B is a diagram illustrating a user interface screen output by the screen motion control apparatus in the landscape mode. Referring to FIGS. 2A and 2B, the interface output by the scroll control device can maintain the same shape regardless of the direction of the screen. Thus, the interface has rotational symmetry.

Referring to Figs. 2A and 2B, the interface may include a reference direction indicating a direction in which to move the screen. The scroll control device can output three reference directions on each side of the screen. The three reference directions output to the respective sides are determined in three directions other than the direction toward the center of the screen with respect to each side among the top direction, bottom direction, left direction, and right direction of the screen. Referring to FIG. 2A, the screen motion control device outputs the upper reference direction 202, the left reference direction 201, and the right reference direction 203 to the upper side of the screen. Since the bottom reference direction 204 faces the center of the screen with respect to the upper side, the screen motion control apparatus does not output the lower reference direction 204 to the upper side.

Referring to FIGS. 2A and 2B, the screen motion control device forms a rectangular area along each side of the screen, and displays a reference direction within each area. However, the form of the interface displayed by the scroll control device is not limited to the rectangular shape. As another example, the scroll control device may form an elliptical or circular area, and may display a reference direction within each area. Further, the screen motion control device can display only the reference direction without displaying the formed area to the user.

The screen motion control device can receive the direction in which the screen is to be moved by the user by outputting the interface. For example, when the user selects the left reference direction 201, the screen motion control device can move the screen to the left direction. Further, the screen motion control device can determine to what extent the user moves in the leftward direction based on the contact time when the user touches the hand end in the left reference direction 201. [

According to one embodiment, the scroll control device can output an interface to only one side of the screen. That is, the screen motion control apparatus can output only the upper side of the interface, and only the upper reference direction 202, the left reference direction 201, and the right reference direction 203 can be output to the screen at this time. The scroll control device can select either side of the screen to output the interface based on the touch input of the user or the software to be executed. This will be described later in detail.

FIG. 3 is a flowchart illustrating an operation performed by the scroll control apparatus according to an exemplary embodiment of the present invention. The screen motion control apparatus can move the screen by executing software for the screen motion control method. The software for the scrolling control method may include a form of instruction code for the scrolling control method.

In step 310, the screen motion control apparatus according to an exemplary embodiment may output an interface including a reference direction indicating a direction in which a screen is to be moved to a screen. The scroll control device can output the interface based on the request of the running software. For example, the map navigation software may request the scroll control device to output an interface. The screen motion control device may overlap the interface with the screen generated by the map searching software in response to the request.

According to another embodiment, the scroll control device can output the interface based on the touch input of the user. That is, the scroll control device may not output the interface until the user performs the touch input.

In step 320, the scroll control device according to an exemplary embodiment may detect a touch input of a user. The scroll control device can identify which reference direction the user has selected based on the coordinates of the touch input. If the coordinate of the touch input is at the boundary of the reference direction, the scroll control device can identify which reference direction has been selected according to the measured pressure. That is, the screen motion control apparatus can identify that the user has selected the reference direction to which the pressure is increased.

Further, the screen motion control device can measure the time (contact time) when the user performs the touch input. The scroll control device can identify a contact time of 0.2 seconds or less.

In step 330, the scroll control device according to one embodiment can identify which time period the contact time is included. When the contact time is between 0 seconds and 0.2 seconds, the scroll control device can classify the contact time into the first time interval. When the contact time is between 0.2 seconds and 0.5 seconds, the scroll control device can classify the contact time into the second time interval. When the contact time is 0.5 seconds or more, the scroll control device can classify the contact time into the third time zone.

In step 340, the screen motion control apparatus according to one embodiment can move the screen based on the touch input of the user. The scroll control device can move in real time while the user touches the reference direction. According to another embodiment, the scroll control device can move the screen after the user stops the touch input.

The scroll control device can determine the direction in which to move the screen based on the selected reference direction. The screen motion control apparatus can determine the distance to move the screen based on the time interval including the contact time and the width of the screen corresponding to the selected reference direction.

More specifically, when the contact time is included in the first time period, the screen motion control apparatus can move the screen along the reference direction selected to be 1/3 to 1/2 times the width of the screen corresponding to the selected reference direction have. When the contact time is included in the second time slot, the screen motion control apparatus can move the screen along a reference direction selected by a size of one-half to one-half of the width of the screen corresponding to the selected reference direction. When the contact time is included in the third time period, the screen motion control device can move the screen along the reference direction selected by one to two times the width of the screen corresponding to the selected reference direction.

Therefore, the scroll control device can move the screen to three different lengths with respect to the three pointers. The screen motion control apparatus discretely determines the distance to move the screen according to the time interval, so that the user can more precisely control the distance to move the screen. This will be described in more detail with reference to Figs. 4A to 4B.

4A and 4B are views illustrating an example in which the screen motion control apparatus according to an embodiment of the present invention moves a screen based on a touch input of a user. 4A is a diagram showing a moment when a user selects a reference direction.

Referring to FIG. 4A, a map may be displayed on screen 402. The user can move the map by rubbing the screen 402 directly or by selecting a reference direction included in the interface. Assume that the user has touched the right reference direction 401 included in the interface for 0.15 seconds.

The scroll control device can determine the direction to move the screen 402 or the distance to move the screen 402 based on the touch input of the user. Since the direction in which the screen 402 is moved is determined based on the selected reference direction, the screen 402 can move in the right direction.

The distance to move the screen 402 may be determined based on the contact time of the touch input and the width of the screen corresponding to the selected reference direction. Since the right reference direction 401 has been selected, the distance to move the screen 402 can be determined based on the horizontal width 403 of the screen.

The scroll control device can determine the distance to move the screen based on the time period including the contact time. According to the above assumption, the user has touched the right reference direction 401 for 0.15 seconds, and 0.15 seconds is included for the first time period. Accordingly, the screen motion control device can move the screen 402 along the right reference direction 401 by a magnitude of 1/3 to 1/2 times the width 403 of the screen.

4B is a diagram showing a result of moving the screen based on the touch input of the user by the scroll control device. Referring to FIG. 4B, it can be seen that the screen 402 has moved about 1/3 times the width 403 of the screen along the right reference direction 401. Since the screen 402 is moved discretely along the time span, the distance by which the user moves the screen can be more accurately determined. In addition, since the distance to move the screen 402 can be set differently for each of the three time periods, the user can more freely control the distance to move the screen 402.

According to one embodiment, the scroll control device may move the screen based on the measured contact time when the user releases his / her hand on the screen 402. [ In this case, the screen motion control device will move the screen after the user releases his or her hand.

According to another embodiment, the screen motion control device can move the screen in real time while a user is making a touch input. For example, assume that the user touches the right reference direction 401 for 0.4 seconds. The screen motion control device moves the screen 402 along the right reference direction 401 by a factor of 1/3 to 1/2 times the width 403 while the contact time is included in the first time period. When the contact time exceeds 0.2 seconds and the contact time is included in the second time slot, the screen movement control device displays the right reference direction 401 by a magnitude of 1/2 to 1 times the width 403, The screen 402 can be moved further.

0.2 second as a boundary value between the first time interval and the second time interval exemplified in the above embodiments considers the sensitivity and responsiveness of the sensor portion capable of sensing a touch input on a recent touch panel , The user can determine the duration of the touch input, which can distinguish between the differences, heuristically. As another example, 0.5 seconds as the boundary value of the second time interval and the third time can also be determined based on the electrical specifications of the sensor section and the user's experience.

When the screen motion controller divides the contact time into the respective time periods, if the interval between the time periods is too short, the screen 402 will be moved more than the user's intention. On the other hand, if the interval between the respective time periods is too long, the user can touch the screen 402 for a long time. This can make the user uncomfortable.

The 0.2 second and 0.5 second set to the boundary value between the first time period and the third time period in the above embodiments allow the user to move the screen 402 a lot without moving the screen 402 more than the user's intention It is a boundary value that can maintain the contact time without great inconvenience. That is, when the boundary values between the first time interval and the third time interval are set to 0.2 second and 0.5 second, respectively, the user can reach the third time zone without great inconvenience, and further, the first time interval and the second time interval By easily distinguishing the time zones, the distance to move the screen 402 can be adjusted according to the intention.

In addition, the boundary value between the first time interval and the second time interval of 0.2 sec is a minimum time for which the sensor unit can detect the presence or absence of touch by the user and can measure the contact time, and a minimum time Is a boundary value set in consideration of. If the boundary value between the first time zone and the second time zone is set to be shorter than 0.2 second, the sensor unit may not accurately identify the presence or absence of the user's touch.

5 is a flowchart illustrating an operation of outputting an interface by the screen motion control apparatus according to an embodiment of the present invention. The screen motion control apparatus according to one embodiment may perform the operation of FIG. 5 in step 310 of FIG.

In step 510, the scroll control device according to an exemplary embodiment may detect a touch input of a user. The scroll control device can determine whether to output the interface based on the coordinates of the touch input. When the user performs a gesture to move the screen, the scroll control device can decide to output the interface. For example, if the user performs a gesture of rubbing the screen, or if the user touches the edge of the screen, the scroll control device may decide to output the interface.

In step 520, the screen motion control apparatus according to one embodiment can select the side of the screen on which to output the interface, based on the touch input. The screen motion control device can output the interface to the side of the screen located closest to the coordinate of the touch input.

According to another embodiment, the scroll control device can divide the screen into a constant detection area. The scroll control device can select the side of the screen based on the detection area including the coordinates of the touch input. The detection area set on the screen by the scroll control device will be described in detail later.

In step 530, the screen motion control apparatus according to an exemplary embodiment may output an interface to a side of a selected screen. Thereby, the screen motion control device outputs the interface to only one side of the screen, thereby increasing the utilization of the screen.

6A and 6B are diagrams illustrating an example in which the screen motion control apparatus according to an embodiment of the present invention outputs an interface to only one side of the screen 600.

6A is a view showing a state in which a user touches a specific coordinate of the screen 600. [ Referring to FIG. 6A, when the map searching software is running, a map may be displayed on the screen 600. FIG. In order to increase the utilization of the screen, the screen motion control device may not output an interface capable of moving the screen while there is no touch input. When the user touches the specific coordinate 610 of the screen, the scroll control device can determine whether to output the interface based on the specific coordinate 610. [

Referring to FIG. 6A, since the specific coordinate 610 is located at the edge of the screen, the scroll control device can decide to output the interface. Furthermore, the screen motion control device can determine to output the interface to the right side since the right side is closest to the specific coordinate 610 among the sides of the screen. According to another embodiment, when the specific coordinate 610 is located at the edge of the screen, the screen motion control device can output an interface to the variable portion of the screen.

6B is a diagram showing an example in which the scroll control device outputs the interface 620 to the right side of the screen. Referring to FIG. 6B, the scroll control device may not output the interface to the other side except the right side. Since the screen motion control apparatus does not output the interface to the side of the screen that is distant from the specific coordinate 610, the utilization of the screen can be increased.

According to one embodiment of the present invention, the screen motion control device can output an interface to a side of a screen corresponding to a detection area included, based on whether a specific coordinate 610 is included in a specific detection area of the screen. The screen motion control device can set the detection area by dividing the screen before the interface is displayed.

7A to 7C are views showing an example of a detection area according to an embodiment of the present invention. When the user touches the coordinates in the specific detection area, the screen motion control device can output the interface to the side of the screen corresponding to the specific detection area.

Referring to FIG. 7A, the screen motion controller can set five detection areas 701, 702, 703, 704, and 705 on the screen. The detection areas 701, 702, 703, and 704 are areas set by the number of sides of the screen, and can be set to include each side of the screen. For example, the detection area 701 includes the right side of the screen, the detection area 704 includes the upper side of the screen, the detection area 703 includes the left side of the screen, and the detection area 702 ) May include the bottom side of the screen. The detection area 705 may be set to be not included in the detection area 705 by being spaced from a predetermined distance from all sides of the screen. The distance that the detection area 705 is spaced apart from the side of the screen may be set differently for each side. When the user selects the detection area 701, the scroll control device can output the interface 706 to the right side associated with the detection area 701. [

The scroll control device may not output the interface if the selected detection area is not related to the side of the screen. Referring to FIG. 7A, it can be seen that the detection area 705 does not include any sides of the screen.
