Description

Technical Field [0001] The present invention relates to a method and an apparatus for scrolling a screen of a display device,

The present invention relates to a technology for controlling a display screen of a display device (for example, a mobile phone, a TV, a tablet, etc.), and is particularly mounted on an input device (TV remote control, a touch-based smartphone, a tablet, etc.) capable of touch input. The present invention relates to a screen scrolling method and apparatus for controlling a list view on a display using a motion sensor (gyroscope, acceleration sensor).

The electronic device directly controlled by the user includes at least one display device, and the user may control the electronic device through the input device while watching various operation states or application operations of the electronic device through the display device. In particular, a portable terminal manufactured to be carried by a user, such as a mobile phone, does not have a four-way button for manipulating up, down, left, and right movements due to its limited size, and an input device capable of user's screen touch input (i.e., A method of providing a user interface with a touch screen) has been widely provided.

In particular, in the case of explaining a portable terminal as an example, the screen scrolls in a list view state in which a plurality of related items including a plurality of bars, a plurality of boxes, or a plurality of icons are displayed, including an SMS call item and an address book. Provide for the movement of list items. At this time, in the method of providing a user interface through the touch screen, in order to manipulate the movement of the list item, drag (drag, the user's finger or the stylus pen moves to another point while touching one point on the touch screen, and then touches it after stopping). Or flick (while the user's finger or stylus pen touches a point on the touch screen, then quickly moves in either direction to release the touch). When there is a drag input, the screen scroll operation is performed in the list view state according to the direction and the movement state corresponding thereto. If there is a flick input, the screen scroll is rapidly performed in the corresponding speed and direction, Performs a stopping operation by reducing the speed.

However, in this case, when there are many list items, it is necessary to continuously perform several dragging or flicking operations to reach a desired list item, resulting in inconvenience to the user, and even when it is desired to check the lists slowly, It is necessary to move slowly while touching. Particularly, in the case of a device having a small display size such as a portable terminal, the touch input unit must be used at the same time as the display screen.

Accordingly, an object of the present invention is to provide a method for scrolling a screen of a display device and a device thereof, which do not require much manipulation in controlling a list view on a display which is more convenient.

Another object of the present invention is a display device that can control the list view with a minimum of movement without touching, in the case of a lot of movement or slow continuous movement to control the list view on the display, etc. The present invention provides a method and apparatus for scrolling a screen.

According to another aspect of the present invention, the present invention provides a method for scrolling a screen of a display device; Changing an inclination section coordinate system to match a reference inclination of an initial position section among a plurality of preset inclination sections at the start of the screen scroll mode operation; Identifying a slope section of the changed coordinate system according to a slope of a current device; Performing a screen scrolling operation according to a preset reference scroll speed in the checked slope section; And stopping the screen scrolling operation when the preset scroll stop condition occurs.

As described above, the present invention is inclined when the user tilts the device at a predetermined angle before stopping the movement of the list after one flick, even if the user does not repeatedly move or drag the flick during the list view control. Since the list can be continuously moved at an angle corresponding to the angle, it can be conveniently used when the list needs to be flicked or dragged in a long section, or when the list is moved slowly. In addition, in the case of a portable terminal using a touch input together with the display, it is possible to scroll the list without touching the screen so that the screen can be used without covering the screen.

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

1 is a schematic block diagram of an apparatus for performing screen scrolling of a display apparatus according to an embodiment of the present invention. Referring to FIG. 1, a device according to the present invention is generally configured as an LCD screen, and displays various application execution images, various operation states, menu states, list views, etc. of the corresponding device, and may be implemented as a touch screen structure. A display unit 13; It is composed of a touch screen control and the like connected to the display unit 13 to receive various touch input manipulations of the user, and also has buttons for a plurality of operation manipulations which are mechanically provided to the keypad or the exterior housing of the corresponding device. An operation unit 14 for receiving a user's operation; A motion sensor unit 15 having a gyroscope, an acceleration sensor, or the like for measuring a rotational state or an acceleration, including an inclination of the device, to detect a motion state of the device; A control unit 12 which collectively controls each of the functional units, and controls the operation of the apparatus 1 as a whole including the list view control operation related to the present invention; And a storage unit 16 which stores operation programs related to the operation of the controller 12 and data related to various applications and list views.

When the apparatus is a portable terminal, for example, the communication unit having an antenna for wireless communication and performing a radio signal processing operation for a wireless communication function; A voice processor for processing a voice signal may be further provided. Alternatively, when the device is, for example, a TV remote control, a short range communication module such as an infrared communication module or Bluetooth for communicating with the TV main body device may be provided. In this case, list items stored in the storage unit 16 may be provided in the TV main body device.

Referring to the list view control method according to the present invention that can be performed in the apparatus that can be configured as described above in detail, the present invention proposes a new user interface method in controlling the list view on the display, and touch the finger on the screen Without a touch input (or without a touch input), or after an initial single touch input, a method of controlling the scrolling speed of the list view using the tilt of the corresponding device is proposed.

To this end, in an embodiment of the present invention, as shown in FIGS. 2 and 3, a plurality of slope sections are preset based on one preset axis for the device 1. For example, the plurality of slope sections include forward (+) slope sections (A and B sections) and backward (-) slope sections (C and D) sections based on the initial position section (section O), which will be described later. Can be divided into In the example of FIGS. 2 and 3, it can be seen that an inclination section according to the state is set in a state in which the corresponding device (terminal) 1 is vertically set. In this case, as shown in FIG. 5, a list view in which bar items are displayed in a plurality of rows on the display screen 130 may be scrolled up and down.

As shown in FIG. 4, when each slope section is referred to as section A, section B, section O, section C, and section D, for example, in each slope section, the center slope is a reference slope of the corresponding slope section, Ta, Tb, To, Tc, and Td are respectively determined. In addition, reference speeds of the screen scroll are set to Va, Vb, Vo, Vc, and Vd for each inclination section. The magnitude of each reference scroll speed is divided as Va> Vb> Vo (= 0)> Vc> Vd when Vo is regarded as the speed 0 at a standstill. At this time, the sign (+) of Va and Vb and the sign (-) of Vc and Vd are different from each other. That is, as in the example shown in FIG. 5, when the flick input 132 occurs in the up (+) direction of the screen, the screen view of the list view is moved up or down from the top. The screen scrolling operation may be performed so that the sign of the screen scrolling speed is set to a negative number or a positive number, respectively.

As described above, the inclination section and related information may be set in advance, and the number of the plurality of inclination sections, the scroll direction, and the speed setting may be variously set according to the user's convenience. In addition, for example, the screen scrolling speed of the list view may also be continuously changed according to the degree of inclination in a section other than the stop section.

As described above, when the inclination section is determined in advance, in the exemplary embodiment of the present invention, when the list view state is in the screen scroll mode, the inclination of the corresponding device at the time of the current screen scrolling mode is used as a reference, and the current tilt of the corresponding device is determined. Is set as the reference slope of the initial position section (O section) in the tilt section.If the tilt of the device is changed so that the tilt of the device falls outside the initial position section and corresponds to another tilt section, the current screen scrolling speed is maintained or the tilt is set. The screen scroll speed is changed according to the scroll speed set in the section.

For example, if there is a flick input 132 as shown in FIG. 5, the screen scrolls while the screen scroll of the list view is decelerated while the finger is released. At this time, the slope of the device at the instant of the flick is the reference slope. At this time, before the screen scrolling stops completely, if the inclination of the terminal enters section A (or section C) by tilting the terminal, the scrolling speed Vi (hereinafter referred to as an entry speed) is maintained at the moment of entry. Thereafter, before there is an additional touch input or a stop condition of the screen scrolling operation such as the terminal returning to the initial position and the screen scrolling is completely stopped, the screen scrolling operation may be continuously performed according to the tilt of the terminal.

An example of the operation of the present invention will be described with reference to the entry speed Vi at the moment when the inclination of the terminal enters the section A or section C.

1) 0 <Vi (entry speed) <Va

Set the entry speed (current speed Vi) to the scroll speed in section A (i.e., maintain the current screen scroll speed), and adjust the coordinate system of the slope section to match the current slope of the terminal to the reference slope Ta in section A. By changing, the coordinate system is adjusted to the current tilt of the terminal. In this case, when the terminal is further inclined to enter section B, the scroll speed is set to the reference scroll speed Vb of section B, and when the terminal returns to section A from section B again, it returns to the original section A rather than the entry speed Vi. Change the screen scroll speed to the preset scroll speed Va.

2) [Va <Vi (entry speed) <Vb] or [Vb <Vi (entry speed)]

The entry speed (current speed Vi) is set as the scroll speed of section B, and the coordinate system of the slope section is changed to match the current slope of the terminal to the reference slope Tb of section B. In this case, unless the terminal is further inclined, the current screen scrolling speed is maintained even when the terminal is inclined more than section B. If the terminal is inclined again and returns to the section A, the original A is not the entry speed (Vi). Return to Va set in the section.

3) 0> Vi (entry speed)> Vc

The entry speed (current speed Vi) is set as the screen scrolling speed of section C, and the coordinate system of the slope section is adjusted to the current tilt of the terminal so that the current slope of the terminal matches the reference slope Tc of the section C. In this case, if the inclination of the terminal further enters the D section, the scroll speed is set to Vd, and when the terminal returns to the C section, the screen scroll speed is set to Vc.

4) [Vc> Vi (entry speed)> Vd] or r [Vd> Vi (entry speed)]

The entry speed (the current speed Vi) is set to the speed of the D section, and the coordinate system of the slope section is adjusted to the current slope of the terminal so that the current slope of the terminal matches the reference slope Td of the D section. In this case, unless the terminal is further allocated, the current scroll speed is maintained even when the terminal is inclined further, and when the terminal is inclined again and returns to the section C, Vc, which was originally set in this interval, is not the entry speed Vi. Return to

As described above, the section-specific operation may be performed. However, if the section angle is not divided and the inclination angle increases outside the stop section, the speed of the screen scrolling is proportionally increased. In this moving state, if the terminal is inclined more than a preset reference (that is, when it is out of the stop section), the reference of the terminal tilt is set based on the entry speed at that moment, and then the entrance speed is adjusted according to the degree of inclination. As a guide, the screen scrolling speed can be increased or decreased.

Of course, as in the case of using the existing UI, if there is no large change in the inclination of the terminal (when the inclination of the terminal is within a preset stop section), it is possible to perform the operation according to the normal drag, flick and the like in parallel.

6 is a flowchart illustrating a screen scrolling operation of the display device according to an exemplary embodiment. Referring to FIG. 6, referring to a screen scrolling operation performed in a list view display state according to an embodiment of the present disclosure, first, in step 602, a check is performed to determine whether a flick input has occurred. Proceed. In step 604, the speed (sign and speed) of the currently generated flick input is checked. In step 606, screen scrolling is started according to the flick input speed.

Thereafter, in step 608, the inclination of the terminal is checked to determine whether the variation of the terminal in comparison with the initial position (that is, the position at the flick input) is within a preset reference value. If the determination result is within the threshold value, the process proceeds to step 610 and if it is not within the threshold value, the process proceeds to step 620.

In step 610, the current screen scrolling speed is decreased by a certain amount. In step 612, it is determined whether there is an additional touch input or the screen scrolling speed becomes zero. If it is determined that there is an additional touch input or the screen scroll speed becomes 0, the process proceeds to step 614 to stop the screen scrolling operation. Otherwise, the process returns to step 608 to repeat the above steps.

On the other hand, in step 608, when the terminal slope is out of the preset reference value compared to the initial position (that is, the position at the flick input), in step 610, the current screen scroll speed is maintained according to an embodiment of the present invention. In addition, the scroll speed may be changed according to the change in the slope. Thereafter, in step 630, it is determined whether a preset scroll stop condition, for example, a touch input or a terminal inclination returns to an initial position and the screen scrolling stops completely, and if so, the flow proceeds to step 614.

In each of the above steps, except for steps 608, 620, and 630, the remaining steps may be similar to a screen scrolling operation performed when a flick is input in a list view display state.

FIG. 7 is a detailed operation flowchart of the main steps of FIG. 6, and shows an example of the detailed operation flow of step 620, which is a characteristic operation step of the present invention illustrated in FIG. 6. Referring to FIG. 7, first, in step 621, the current screen scrolling speed is maintained. In operation 622, a gradient section corresponding to the current screen scroll is checked among a plurality of preset slope sections. Thereafter, in step 623, the slope interval coordinate system is changed so that the reference slope preset in the corresponding slope interval matches the current slope.

Thereafter, in step 624, the reference slope section of the changed coordinate system according to the current slope is checked. In step 625, the screen scroll operation is performed according to the reference scroll speed preset in the checked slope section. In this case, when there is no change in the checked slope section, the current screen scrolling speed is maintained as it is. Accordingly, the initial screen scrolling speed maintained in step 621 may be continuously maintained. In addition, when the checked tilt section returns to the tilt section of the initial position, the screen scroll speed may be gradually decreased until it becomes zero.

Thereafter, in step 626, it is determined whether there is a touch input. If there is a touch input, the process proceeds to step 624, and the process is repeated, and if there is a touch input, the process proceeds to a later step.

As described in step 626, the embodiment of the present invention concludes whether to stop the screen scroll operation according to whether or not the touch input, in addition to this in another embodiment the screen to detect that the screen scroll speed is zero You can also perform the operation by stopping the scroll operation.

8 is a flowchart of a screen scrolling operation of a display device according to another embodiment of the present invention. The method according to another embodiment of the present invention shown in FIG. 8 performs a screen scrolling operation without a flick input, for example, automatically performs the screen scrolling mode operation shown in FIG. 8 according to the start of performing the list view display operation. It can be preset to start with. Referring to FIG. 8, first, in step 802, the slope interval coordinate system is changed to match the reference slope of the initial position interval among a plurality of preset slope intervals.

Thereafter, in step 804, the slope interval of the changed coordinate system according to the slope of the current terminal is checked. In operation 806, the screen scroll operation is performed according to the preset reference scroll speed in the checked slope section. In this case, when the checked tilt section returns to the tilt section of the initial position, the screen scroll speed may be gradually decreased until it becomes zero.

Thereafter, in step 808, it is determined whether there is a touch input. If there is no touch input, the process returns to step 804 and repeats the above process, and if there is a touch input, the process proceeds to step 810. In step 810, it is determined whether a scroll stop condition is set in advance, such as whether there is an additional touch input, and when the screen scroll stop condition is not met, the process returns to step 802 and repeats the above process. In this case, the screen scrolling mode is terminated.

Referring to the operation illustrated in FIG. 8, when entering the screen scrolling mode as shown in the list view display, the screen scrolling speed is changed by changing the screen scrolling speed according to the degree of changing the inclination based on the inclination of the initial terminal at the entry point without any flick input. It can be seen that the operation is performed. In this case, according to the touch input in step 808, it can be seen that the initial position of the inclination of the terminal and the reference slope interval coordinates corresponding thereto are reset. In this case, the flick input may not be necessary, and therefore, when viewed in the device structure illustrated in FIG. 1, it may not be necessary to include the display unit 13 having the touch screen structure.

In FIG. 10, unlike the above-described embodiments, the inclination section may be set according to rotation of the terminal clockwise or counterclockwise instead of tilting forward or backward in a vertically placed state.

In FIG. 11, unlike the above-described embodiments, the inclination section may be set according to a state in which the terminal is inclined to the left or right instead of tilting forward or rearward in a vertical state.
