In the following embodiments, it is assumed that the display module is arranged in a mutual layer structure with the touch pad and operates as a touch screen.

1st Example

A method of operating the portable terminal according to the first embodiment of the present invention will be described with reference to FIGS. FIG. 4 is a flowchart illustrating a method of operating the portable terminal according to the first exemplary embodiment of the present invention, FIG. 5 is a state diagram of a display screen of the portable terminal in which an operation method related to the first exemplary embodiment of the present invention is implemented, Is a graph showing an operation method related to the first embodiment of the present invention.

As shown in (5-1) of FIG. 5, it is assumed that a plurality of icons are displayed on the display screen 200 of the portable terminal 100 (S41). An icon 210 for accessing the Internet will be described as an example.

A plurality of functions may be assigned to the Internet access icon, and the plurality of functions may be separately executed according to the present embodiment. Hereinafter, an operation method according to an embodiment of the present invention will be described in more detail, assuming that three functions are assigned to the Internet access icon 210 and that the three functions are executed separately.

As shown in (5-2) and (5-3) of FIG. 5, when the Internet access icon 210 is touched once with a pointer such as a finger or a stylus pen, Is released. Hereinafter, such an operation is referred to as a "simple touch" operation. Then, the first function for connecting the Internet to the mobile terminal 100 via the HSDPA is executed (S42, S43 (Yes), S44 (No), S45 (Simple Touch), S46).

As shown in (5-2) and (5-3) of FIG. 5, when the Internet access icon 210 is touched once and then touched as a pointer, 5 (5 - 4). Hereinafter, such an operation is referred to as a "double touch" operation. Then, for example, a second function for connecting the Internet to the mobile terminal 100 via Wimax is executed (S42, S43 (Yes), S44 (No), S45 (Double Touch), S47).

As to the execution of the third function, the touch is maintained after the internet connection icon 210 is touched as a pointer, as shown in (5-2) of FIG. Then, as shown in (5-5) in FIG. 5, a circular indicator 215 for displaying the time at which the touch is held (hereinafter referred to as "touch holding time") is generated do. The indicator 215 indicates a value proportional to the touch holding time. 5 (5-5) to (5-7) illustrate that the indicator 215 is generated separately from the icon 210. However, the present embodiment is not limited to this, and the indicator 215 May be generated to be a part of the icon 210. [ 5 (5-5) to (5-7), the indicator 215 is shown as being circular. However, the present embodiment is not limited to this and can be expressed in various forms. This will be described as a separate embodiment.

Assume that the touch is maintained longer than a predetermined first time interval (e.g., 5 seconds). In FIG. 5 (5-6), the indicator is maintained for more than the first time interval by being completely filled.

At this time, the touch is released from the icon 210 as shown in (5-7) of FIG. 5, and the icon 210 is again displayed within a second time interval (for example, 0.5 seconds) And is re-touched. Hereinafter, this operation is referred to as a " long double touch "operation. Then, the mobile terminal 100 executes a third function (e.g., S42, S43, S44, S48, S50, and S51) in which the Internet access details via HSDPA and / ].

It is not necessary that the long double touch operation be performed for all the icons. That is, the function to be executed corresponding to the long double-touch operation may not be allocated to the dialing icon 220 among the icons shown in (5-1) of FIG. In this case, when the long double touch operation is performed on the dialing icon 220, it may be configured such that no indicator for indicating the touch holding time in association with the dialing icon 220 is displayed. Accordingly, the terminal user can easily recognize that the function corresponding to the long double touch operation is not easily assigned to the dialing icon 220 (S42, S43, S44, S48, ), S49].

Hereinafter, referring to FIG. 6, the long double touch operation will be described in more detail.

The long double touch operation is different from the simple touch operation described above in connection with (5-2) and (5-3) of FIG. 5 in that the long double touch operation is performed by two successive touch operations.

There may be a long simple touch operation (or long-key operation) which is different from the simple touch operation by performing the similar operation to the simple touch operation but not keeping the simple touch maintenance time longer than a predetermined time interval. It will be understood by those skilled in the art that the long touch operation will be readily apparent to those skilled in the art, and a detailed description thereof will be omitted for the sake of simplicity.

Nevertheless, the long simple touch operation is performed by one touch operation as in the simple touch operation, but the long double touch operation is easily distinguished from the long simple touch operation in that the long simple touch operation is performed by two consecutive touch operations .

On the other hand, the long double-touch operation and the double-touch operation are similar to each other in that they are performed through two touch operations, namely, a first touch, a first touch release, a second touch, However, the above two operations are distinctively different for the following reasons.

Whether or not the double touch is operated depends on the time interval? T ₁₃ between the first touch point t ₁ and the second touch point t ₃ as shown in (6-1) of FIG. 6 have. In order for the double touch to be operated, the time interval? T ₁₃ between the first touch point t ₁ and the second touch point t ₃ must be smaller than a predetermined time interval T ₁ (for example, 0.5 seconds) do.

When the double touch operation is performed in accordance with the above conditions, the function related to the double touch operation can be performed at the second touch point or the second touch point.

Whether or not the long double touch is operated can be determined by comparing the time interval? T (t) between the first touch timing t ₁ and the first touch release timing t ₂ , as shown in (6-2) ₁₂ ). And, in order to be the long Double touch is the operation of the first touch point in time (t ₁₎ and the first touch-off time (t ₂₎ the time interval (Δt ₁₂₎ between, that is, the first touch maintained time is a predetermined time interval T ₂ (E.g., 5 seconds).

In addition, whether or not the long double touch is operated may be related to the time interval? T ₂₃ between the first touch release time t ₂ and the second touch time t ₃ . In this case, the time interval? T ₂₃ between the first touch release time point t ₂ and the second touch time point t ₃ should be smaller than the predetermined time interval T ₃ (for example, 0.5 seconds).

When the long double touch operation is performed in accordance with the above conditions, a function related to the long double touch operation can be performed at the second touch time point t ₃ or the second touch release time point t ₄ .

The concept of the long double-touch operation described in connection with (6-2) in FIG. 6 is not limited to itself, but may be modified as in (6-3) of FIG.

The modified long double touch operation in (6-3) of FIG. 6 is performed by the time interval? T ₁₃ between the first touch point in time t ₁ and the second touch point in time t ₃ and the second touch point in time t ₃ and the second time interval between the touch-off point _{(t 4) (Δt 34)} , i.e. is related to the two time intervals.

In order for the deformed long double touch to be operated, the time interval? T ₁₃ between the first touch point t ₁ and the second touch point t ₃ is shorter than a predetermined time interval T ₄ (for example, 0.5 seconds) as well as to be smaller, and the second touch point in time (t ₃₎ and a second touch-off point (t ₄₎ the time interval (Δt _34), i.e. the second touch hold time is a predetermined time interval t ₅ (e.g., 5 seconds) between .

When the strain Long double touch operation is performed according to the above conditions, the function associated with the long variant double touch operation can be performed on the second touch-off point (t _4).

When the deformed long double touch operation is performed, the indicator described above with reference to FIG. 5 may be displayed during the second touch holding time.

It should be noted that T ₁ to T ₅ may be the same or different from each other.

In the following embodiments, it is assumed that a long double touch operation is performed in accordance with (6-3) of (6-2) and (6-3) in FIG.

Second Example

In the first embodiment, in order to perform the long double touch operation, the second touch must be performed in a state where the first touch holding time? T ₁₂ is longer than the preset time T ₂ . However, in the first embodiment, the first touch holding time is calculated only as the time between one touch and the touch release. However, the first touch holding time may be calculated as a plurality of times of touch and touch release. This will be described as a second embodiment.

A method of operating the portable terminal according to the second embodiment of the present invention will be described with reference to FIGS. 7 and 8. FIG. FIG. 7 is a flowchart illustrating a method of operating the portable terminal according to the second embodiment of the present invention, and FIG. 8 is a graph illustrating an operation method related to the second embodiment of the present invention.

Assume that an icon 210 pre-allocated with a function related to the long double-touch is displayed on the display screen 200 (refer to (5-1) in FIG. 5).

A first part touch is performed on the icon 210 (S71). Then, as shown in (8-2) of FIG. 8, an indicator 215 for displaying a first touch holding time associated with the icon 210 at a time t ₁ ' Is displayed.

Then, the first partial touch is continuously maintained. Then, as shown in the graph I area of (8-1) in FIG. 8, the first touch holding time? T ₁₂ is increased as long as the first part touch is maintained. Then, as shown in (8-3) of FIG. 8, the indicator 215 indicates a value corresponding to the increased first touch holding time? T ₁₂ (S72).

Then, it is assumed that the first part touch is released in a state in which the first touch holding time is not equal to the predetermined time (T ₂ ) (S73, S74 (No)). Then, as shown in the graph II area of (8-1) in FIG. 8, the first touch holding time? T ₁₂ is decreased after the time t ₂ 'at which the first partial touch is released. Then, as shown in (8-4) of FIG. 8, the indicator 215 displays a value corresponding to the gradually decreasing first touch holding time? T ₁₂ (S75).

Next, when the second partial touch is performed, as shown in the graphs III and IV in (8-3) of FIG. 8, after the time point t ₃ 'at which the first partial touch is performed, touch the holding time (Δt ₁₂₎ is again increased [S71, S72]. First touch the holding time (Δt ₁₂₎ is when the time (t ₄ ') to reach the predetermined time (T _2), with the indicator 215, as shown in (8-5) of Figure 8 is the 1 touch the holding time (Δt _12), this indicates that it has reached the predetermined time (T ₂₎ [S74 (Yes).

Then, when the icon is re-touched after the time point t ₅ 'at which the second part touch is released, the long double touch operation is performed [S 76, S 77]. The first touch holding time? T ₁₂ after the second partial touch canceling time may be either maintained as shown by the A curve line or decreased as shown by the B curve line.

Up to a time t ₄ 'at which the predetermined time T ₂ is reached after the time t ₁ ' at which the first touch holding time Δt ₁₂ starts to accumulate are summarized as follows.

The first part touch holding time? T ₁₂ = the first part touch holding time? T ₁₂ '- the first part touch canceling holding time? T ₂₃ ' + the second part touch holding time? T ₃₄ '

Third Example

In the above-described first and second embodiments, the long double-touch operation is used to perform one of the various functions when various functions are assigned to one icon. The long double-touch operation may be used for the purpose of preventing the unintended touch operation of the terminal user in addition to the above-described purpose. This will be described as a third embodiment.

A method of operating the portable terminal according to the third embodiment of the present invention will be described with reference to FIGS. 9 and 10. FIG. FIG. 9 is a flowchart illustrating a method of operating a portable terminal according to a third exemplary embodiment of the present invention, and FIG. 10 is a state diagram of a display screen of a portable terminal in which an operation method related to the first exemplary embodiment of the present invention is implemented.

2. Description of the Related Art Generally, a portable terminal is equipped with a locking function for the purpose of preventing unintended touch operation of a terminal user. However, when the locking device is configured to operate the locking function by the icon on the touch screen, when the portable terminal is being stored in a pocket bag or the like, the icon is easily touched by the surrounding object by an external shock, It can be turned ON or OFF. When the long double-touch operation described in the above-described embodiment is used in association with the icon having a high importance such as the lock function or the power on / off, the unintentional operation described above can be significantly prevented. Let's look at this in more detail.

10 (10-1), a lock function icon 230 is displayed on the display screen of the portable terminal 100 (S91). The lock function icon 230 indicates that the mobile terminal 100 is currently in the unlock function state. In this situation, the terminal user performs a first touch on the lock function icon 230 (S92).

Then, as shown in (10-2) of FIG. 10, an indicator 235 for indicating the time when the first touch is maintained is generated in association with the icon 230

Next, as shown in (10-3) of FIG. 10, the terminal user keeps the first touch for a predetermined time (i.e., the first time interval) (e.g., 5 seconds) (S93, S94). Then, the indicator 235 indicates that the first touch holding time has exceeded the predetermined time.

Then, as shown in (10-4) in FIG. 10, the terminal user releases a second touch (i.e., re-touch) the icon 230 immediately after releasing the first touch (i.e., within a second time interval) (S95 (No), S96).

Then, as shown in (10-5) of FIG. 10, the lock function icon 230 shows that the mobile terminal 100 enters the lock function setting state (S97).

On the other hand, when the first touch holding time exceeds the preset time too much, the first touch is likely to be applied and maintained regardless of the intention of the user. Accordingly, when the first touch is held for a much longer time (for example, one minute) than the first time interval, as shown in (10-6) in FIG. 10, It is possible to return to the state of (10-1) in FIG. 10 so that the lock function state can not be changed even if the second touch is performed on the icon 230, , S98].

Fourth Example

In the above embodiment, a circular indicator for indicating the first touch holding time has been introduced. However, the indicator is not limited to the circle. The various types of indicators will now be described.

A method of operating the portable terminal according to the fourth embodiment of the present invention will be described with reference to Figs. 11A to 11F. 11A to 11F are state diagrams of a display screen of a mobile terminal in which an operation method according to a fourth embodiment of the present invention is implemented.

(11a-1) to (11a-3) of FIG. 11A show that a bar-shaped indicator 215 appears when an icon 210 is subjected to a long double-touch operation. As the first touch holding time is increased, the bar of the indicator 215 is gradually filled with a scale.

FIGS. 11B and 11C illustrate the appearance of the animated indicator 215 when a long double touch is made to one icon 210. FIG. As the first touch holding time increases, the shape of the indicator 215 gradually changes. 11B and 11C show that the indicator 215 is generated separately from the icon 210 described above. However, this may be modified so that, when a long double touch is performed on the icon 210, the icon 210 disappears and instead the indicator 215 of the animation form is generated will be.

In FIG. 11D, when a long double touch is performed with respect to one icon 210, no separate indicator is generated, and the shape of the icon 210 changes in proportion to the first touch holding time. In particular, in FIG. 11D, the icon 210 is gradually increasing in proportion to the first touch holding time. In addition, icons other than the icon 210 may be configured to be smaller in proportion to the size of the icon 210. This is to allow the terminal user to easily perform the second touch when the first touch holding time becomes longer than a preset time by further highlighting the icon.

In Fig. 11E, contrary to Fig. 11D, the icon 210 is shown to be decreasing in proportion to the first touch holding time. In addition, icons other than the icon 210 may be configured to become larger as the icon 210 becomes smaller. This is to further ensure that the terminal user is to input the second touch according to his or her intention when the first touch holding time is equal to or longer than a predetermined time. Thus, the modification of the icon as shown in FIG. 11E is more useful when the terminal user is used to prevent unintended touches.

In (11f-1) of FIG. 11F, a folder icon 240 composed of image files is displayed on the display screen 200 of the portable terminal 100. During the first touch retention time of the double long touch with respect to the icon 240, as illustrated in (11f-2) to (11f-4) It is displayed sequentially at regular time intervals. At this time, the indicator 245 for the folder icon 240 may or may not be generated. Thus, the terminal user has the advantage of being able to quickly review the information in the folder icon 240 during the first touch hold time.

Although not described in FIGS. 11A to 11F, it is also considered that sound or vibration having a magnitude or frequency varying in proportion or in inverse proportion to the first touch holding time of the double long touch is output through the output section as the indicator It will be possible. The indicator according to at least one of the sound and the vibration may be output together with the image indicator on the display screen.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. For example, in the above description, the long double-click operation is performed on the touch screen. However, the present invention is not limited to this, and may be modified to be performed on a touch pad or a keypad.
