Description
The present invention relates to a method and apparatus for changing the display magnification of an object on a touch screen display, and more particularly to a method and apparatus capable of scrolling an object faster on a touch screen display.
The touch screen display means a device capable of receiving a signal through a display by applying a minute current or pressure on the display. There is a point similar to a touch pad in that an input signal is applied through a touch sensor that recognizes a minute current or pressure. However, in the case of the touch pad, the pointer on the display moves according to the relative movement of the touch fan or the finger input on the touch pad, while in the case of the touch screen display, the touch sensor and the touch pad are implemented together to apply a signal to a specific point on the display The difference is that the pointer works at that point.
Thus, when a signal is applied to the touch screen display through a finger or the like, the sensitivity of recognizing the signal is very important. Recently, a capacitive touch screen display having excellent response to an input signal has been developed, and various functions that can be performed through a touch screen display in an electronic device are being developed. The user does not need a separate input device because the user usually makes a selection on the display screen by pointing the GUI object directly on the display screen with a stylus or a finger.
Because of these advantages, touch screen displays have been widely used in mobile devices, and as the use of mobile devices equipped with touch screen displays becomes commonplace, many of the programs that have been performed through computers in the past have also been implemented through mobile devices. Accordingly, a variety of user interfaces have emerged that allow a user to easily interact with a mobile device having a touch screen display. For example, when a user enters commands into a touch screen display panel, user interfaces have emerged that allow specific commands to be entered as intuitive gesture inputs.
As one of such user interfaces, an interface has been introduced in which a user performs a specific input on the touch screen, for example, a drag input to scroll the object.
Scrolling is a scroll that allows you to view a page or object that is not marked on the display by moving the displayed screen up or down or left or right without opening a new window when only a part of the page or object is displayed on the display . In the case of a desktop PC, it is common to place a marker or an indicator on one side of a web-browser or an electronic document to perform a scroll operation through an input device such as a mouse, but in the case of a touch screen display, Because of the direct control over the touchscreen display, scrolling was performed by performing specific input, such as dragging input, on the touch screen display.
In this regard, the conventional user interface on the scroll method in the touch screen display does not provide an efficient and convenient way. For example, if you have a lot of scrolling targets, for example, in the list of music that contains lots of music, you can select the desired music by scrolling. If the desired song is at the end of the music list, I had to constantly apply the drag input until it appeared. This method is very inconvenient in that the electronic document takes a very long time when performing an operation requiring a very long scroll or a large number of scrolling operations, and requires a continuous input of a gesture to maintain the scroll.
Such a problem is more remarkable in a display of a portable mobile device whose size is remarkably small as compared with that of a general display, so that contents, pages, etc. to be displayed can not be displayed on one screen at all.
Accordingly, it is required to develop a method and apparatus capable of performing a scroll more quickly when a task requiring a lot of scrolling is performed through a touch screen display.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a method and apparatus for performing time-efficient scrolling when an object is scrolled on a touch screen display.

2 is a flow diagram of a method for changing the display magnification of an object on a touch screen display, in accordance with an embodiment of the present invention.
Referring to FIG. 2, an input event is generated by one or more touch inputs to an object on the touch screen display (S210).
Here, the input event indicates that an event has occurred that causes enlargement or reduction of the display magnification of the object displayed on the touch screen display. This input event is generated by one or more touch inputs of the user to an object on the touch screen display.
The input event may include a display magnification reduction event and a display magnification enlargement event. The display magnification reduction event is a notification that the display magnification of the object displayed on the touch screen display has been reduced, and the display magnify enlargement event causes an enlargement of the display magnification of the object displayed on the touch screen display This is a notification that something happened.
Whether any of the various types of touch inputs that can be input on the touch screen display causes the display magnification reduction or enlargement event to be generated can be set in advance. For example, the display magnification reduction or enlargement event may be preset to be generated by a drag input to the right (in the case where there is no execution value assigned to the drag input to the right). However, the present invention is not limited to this, and it is also possible to set the display magnification reduction or enlargement event to occur by a multiple tap or a long tap including a tap, a double tap, It is possible.
If desired, the user may select one or more touch inputs (e.g., if there are other touch values assigned to one of the touch inputs, i. E. A drag input in one direction, a tap input, a double tap input, a long tap input, The display magnification reduction or enlargement event may be generated by the input. Whether or not the display magnification reduction or enlargement event is generated when two or more types of touch inputs must be applied or how the display magnification reduction or enlargement event is generated when two or more touch inputs must be applied are not particularly limited. Hereinafter, exemplary methods of the present invention, which apply two or more touch inputs to generate a display magnification reduction or enlargement event, will be described in more detail.
According to an embodiment of the present invention, the display scaling event may be generated when the first touch input is applied following the drag input for scrolling. Here, the fact that the first touch input is applied after the drag input for scrolling means that the drag input for scrolling is applied and the preset first touch input is applied within a predetermined predetermined time.
At this time, when the drag input for scrolling and the first touch input are continuously performed, that is, when the first touch input is started from a point on the touch screen display on which dragging for scrolling has been completed, May occur. For example, when the first touch input is a drag input, a display magnification reduction event may be generated when the drag input as the first touch input is started from a point on the touch screen display where the drag input for scrolling has been completed.
When the display magnification reduction event occurs, the object to be scrolled may be reduced within a range of an identification threshold value at which the user can identify the object while scrolling. The identification threshold value can be determined by the control unit. If the scroll target objects include objects having various identification threshold values such as an image and text, So that each of the scroll target objects is reduced to the identification threshold value.
The first touch input may be one of various types of touch inputs that can be input on the touch screen display. For example, the first touch input may be one of a drag input, a tap input, a double tap, a long tap input, a pinch throw input, and a tap hold input.
When the first touch input is preset as the drag input, the drag input direction as the first touch input may be implemented to be substantially perpendicular to the drag input direction for scrolling. In this case, the user can apply the drag input for scrolling and the first touch input together with an intuitive operation using an input tool such as a finger. Here, when the drag input direction for scrolling and the drag direction of the first touch input are orthogonal to each other, it should be understood that the right angle means a substantial right angle, not an absolute right angle. For example, even when a drag input having an angle of 70 ° to 110 ° with a drag input direction for scrolling is applied, the first touch input is regarded as being applied, so that a display magnification reduction event may be generated.
According to an embodiment of the present invention, the display magnification enlargement event may be generated when a second touch input is applied subsequent to a drag input for scrolling. Here, the fact that the second touch input is applied following the drag input for scrolling means that the drag input for scrolling is applied and the preset second touch input is applied within a predetermined predetermined time.
In this case, when the drag input for scrolling and the second touch input are continuously performed, that is, when the second touch input is started from a point on the touch screen display on which dragging for scrolling has been completed, May occur. For example, when the second touch input is a long tap input, a display magnification enlargement event may be generated when a long tap input as a second touch input is started from a point on the touch screen display where the drag input for scrolling is completed have.
The second touch input may be any one of various types of touch inputs that can be input on the touch screen display, such as a drag input, a tap input, a double tap input, and a long tap input. However, the second touch input is required to be a different kind of input from the above-described first touch input. Here, different types of inputs may include drag inputs whose input directions are different from each other.
In this sense, when the first touch input and the second touch input are all the drag input, the drag direction of the first touch input is implemented as opposed to the drag direction of the second touch input, thereby providing an intuitive user interface. For example, when the drag direction of the first touch input is the right direction, the drag direction of the second touch input may be the left direction. Here, when the drag direction of the first touch input and the drag direction of the second touch input are opposite to each other, the opposite does not mean a numerically exact opposite. For example, the drag direction of the first touch input and the direction forming the angle of 160 ° to 200 ° can be set to the drag direction of the second touch input.
Next, referring to FIG. 2, the display magnification of the object on the touch screen display is changed according to the input event (S220).
Here, the display magnification means that the object is displayed on the touch screen display several times as enlarged or reduced. As described above, when the display magnification reduction event occurs, the display magnification of the object can be enlarged, and when the display magnify enlargement event occurs, the display magnification of the object can be reduced.
The degree to which the display magnification of the object is changed can be determined according to the intensity of the touch input for generating the input event, such as the first touch input and the second touch input. Here, the strength of the touch input may be set to one of the speed of the touch input, the length of the touch input, the time of the touch input, and the number of touch inputs, depending on the type of the touch input. For example, when the touch input is a drag input, the intensity of the touch input may be the length of the touch input, and the display magnification of the object may be greatly changed by the long drag input. In addition, when the touch input is a long tap input, the intensity of the touch input may be the time of the touch input, and the display magnification of the object may be largely changed by long long tap input.
Next, referring to FIG. 2, the object may be scrolled with the display magnification changed (S230).
Since the display magnification of the object on the touch screen display has changed, the degree to which the object scrolls per drag input length for scrolling will also change. For example, if the display scale factor of the object is reduced due to the occurrence of the display scale reduction event, the degree to which the object scrolls per drag input length for scrolling will be increased.
