4 illustrates a structure of a touch screen related to the present invention.

As shown in FIG. 4, the display module 151 according to the present invention forms a mutual layer structure with the touch pad 400 and is configured as a touch screen 500.

As illustrated in FIG. 4, the touch pad 400 includes a quadrangular conductive film 411 made of a transparent conductive material such as indium tin oxide (ITO) and metal electrodes formed at each corner of the conductive film 411. 412-1 to 412-4). The passivation layer 420 may be formed on the conductive layer 411.

The touch pad 400 is a capacitive sensing type position detecting apparatus, and the transmitting side metal electrode is applied by an alternating voltage applied to the transmitting side metal electrodes T: 412-1 and 412-4. Electrical field lines are formed between the electrodes T: 412-1 and 412-4 and the receiving metal electrodes R: 412-2 and 412-3. The formed electric line of force extends to the outside of the touch panel 400 through the passivation layer 420. Accordingly, when the input medium (for example, a user's finger) closes the electric field line by approaching the touch pad 400 or directly touching the touch pad 400, the receiving side metal electrodes R: A change occurs in the phase and magnitude of the current flowing to 412-2 and 412-3. This is because the human body has a capacitance of several pF with respect to the ground, and the user distorts electric force lines formed on the touch panel 400 when the user approaches or touches the finger with the touch panel 400.

In addition, the processors (not shown) configured in the portable terminal 100 may change the input medium by using a current change of the receiving metal electrodes R 412-2 and 412-3 according to a touch operation of the input medium. It is possible to detect the distance close to the position where the touch occurred.

In addition, the input medium may include any object not only a user's finger but also an object capable of recognizing a touch input by distorting an electric force line formed on the touch pad 400.

FIG. 5 is a diagram illustrating a principle of detecting a proximity distance of an input medium using the touch screen of FIG. 4.

As illustrated in FIG. 5, the AC voltage 430 is applied to the transmitting side metal electrode 412-1 among the metal electrodes 412-1 to 412-4 formed on the transparent conductive film 411, thereby transmitting the above-described voltage. Electrical force lines 501 to 503 are formed between the side metal electrode 412-1 and the receiving side metal electrode 412-2. The electric field lines 501 to 503 extend in a vertically upward direction (ie, z direction) of the touch screen 500.

In addition, according to the distance between the user's finger 510 and the touch screen 500, the amount of electric field lines 501 to 503 blocked by the finger 510 is changed. That is, as the finger 510 gets closer to the touch screen 500, the influence of the finger 510 on the electric field lines 501 to 503 increases.

As described above, the influence applied to the electric field lines 501 to 503 by the finger 510 may affect the current applied to the current detectors 440-1 and 440-2 connected to the metal electrodes 412-1 and 412-2. The current detectors 440-1 and 440-2 detect the change in the current and provide it to an analog-digital converter (ADC) 450. Then, the analog-to-digital converter (ADC) 450 converts the amount of change of the current input in the form of an analog signal into a digital value, and provides it to the touch time measuring unit 460.

Then, the touch time measuring unit 460 may recognize that the finger 510 is close to the touch screen 500 from the information on the amount of current change provided from the analog-to-digital converter (ADC) 450. The time that the finger 510 stays within the touch recognition effective distance (ie, 'd1' in FIG. 5) is measured. Accordingly, when the finger 510 stays within the proximity touch recognition effective distance (ie, 'd1' in FIG. 5) for more than a predetermined time (for example, 1 second), the touch time measuring unit 460 according to the present invention. It may be recognized that the proximity touch or direct touch operation according to the present invention is performed. On the other hand, the touch time measuring unit 460 may keep the finger 510 within a proximity touch recognition effective distance (ie, 'd1' in FIG. 5) for a time shorter than a predetermined time (for example, 1 second). In this case, it may be determined that the proximity touch or the direct touch operation according to the present invention is not performed.

As such, when it is determined by the touch time measuring unit 460 that the finger 510 has a touch input based on a proximity touch or a direct touch operation on the touch screen 500, the touch time measuring unit 460 ) Provides the distance detection unit 470 with information about the touch input generation information and the current change amount.

Then, the distance detection unit 460 is a distance between the finger 510 and the touch screen 500 from the information on the amount of current change, that is, the finger 510 is vertically upward from the touch screen 500 ( That is, the distance spaced in the z direction) is calculated.

Specifically, when the finger 510 is located closer than d1 (eg, 30 mm) and farther than d2 (eg, 20 mm) from the vertical upward direction (ie, z direction) of the touch panel 400. (Ie, located between d1 and d2), the distance detector 460 is located within a touch recognition effective distance at which the finger 510 starts detecting whether the touch screen 500 touches an external input medium. By determining, a function corresponding to the proximity touch operation according to the present invention may be provided. Here, the proximity touch refers to a state in which an input medium (for example, a user's finger) is located within the touch recognition effective distance of the touch screen 500 for inputting a user command. The input medium is distinguished from a direct touch operation in which the input medium directly touches the touch screen 500 in that the touch screen 500 is not directly touched.

Further, when the finger 510 is located closer than d2 (for example, 20 mm) and farther than d3 (for example, 10 mm) from the vertical upward direction (ie, z direction) of the touch screen 500 ( That is, when the position is located between d2 and d3), the distance detector 460 may determine that the finger 510 is very close to the touch screen 500.

Further, when the finger 510 is positioned at a distance closer to d3 (eg, 10 mm) from the vertically upward direction (ie, z direction) of the touch screen 500 (ie, located within d3) or the finger ( When the 510 directly touches the surface of the touch screen 500, the distance detector 460 determines that the finger 510 directly touches the touch screen 500 within an error range.

In FIG. 5, the touch operation of the finger 510 is divided into three steps according to the distance between the finger 510 and the touch screen 500, but the touch operation is more precisely performed in four or more steps. Can be distinguished.

Next, the position detector 480 determines the position on the touch screen 500 indicated by the finger 510, that is, the horizontal coordinates in the x and y directions on the touch screen 500, from the information on the amount of change of the current. Calculate The y direction is a direction perpendicular to the x and z directions shown in FIG. 5.

The measured vertical distance between the finger 510 and the touch screen 500 and the horizontal coordinates of the finger 510 on the touch panel 400 are provided to the controller 180. Accordingly, the controller 180 determines a user's command according to the vertical distance and the horizontal coordinate, performs a control operation according to the user command, and also has a predetermined graphical user interface (GUI) on the display module 151. ).

FIG. 6 is a diagram illustrating a principle of position detection of an input medium using the touch screen of FIG. 4.

Electric field lines (not shown) are formed between the -1 and 412-4 and the receiving metal electrodes R 412-2 and 412-3.

When the user's finger 510 is close to the touch panel 400 or directly touches the touch panel 400, a current change occurs in the metal electrodes 412-1 to 412-4. Then, the current detectors 440-1 to 440-4 measure the change in the amount of current, and as described above, the position detector 470 uses the finger 510 to change the amount of current. The horizontal coordinate (ie, xy coordinate) located on the 400 is detected and provided to the controller 180. Accordingly, the controller 180 recognizes a horizontal coordinate on the touch screen 500 that the finger 510 is touching, performs a user command corresponding to the touch operation, and performs an operation on the display module 151. It is possible to provide a predetermined graphical user interface (GUI).

In addition, in FIGS. 5 and 6, the touch time measuring unit 460, the distance detector 470, and the position detecting unit 480 are illustrated separately from each other according to respective functions, but the touch time measuring unit 460 is illustrated. The distance detector 470 and the position detector 480 may be formed in the controller 180.

In addition, in FIGS. 4 to 6, the touch screen 500 having the touch panel 400 according to the capacitive sensing method is taken as an example, and the proximity touch and the direct touch of the input medium with respect to the touch screen 500 are provided. Although the principle of determining whether or not has been described, the type of the touch panel 400 or the touch panel can be provided as long as it can provide a function of detecting a distance between the input medium and the touch screen 500 and a position indicated by the input medium. The arrangement of the metal electrodes 412-1 to 412-4 configured at 400 is not limited.

For example, the touch panel 400 uses the photoelectric sensor using a laser diode and a light emitting diode, a high frequency oscillating proximity sensor, and a magnetic proximity sensor to touch the input medium and the touch. In addition to being able to detect the proximity position between the panels 400, a resistive sensing method for forming a metal electrode on the upper or lower plate and detecting a change in voltage according to the position pressed by the input medium (Resistive Sensing) Type) and the capacitive sensing scheme may be implemented by combining with each other.

In FIG. 17A, reference numeral 512 denotes the web browser in which an input medium (for example, a user's finger) 510 is displayed on the touch screen 500 within a touch recognition effective distance of the touch screen 500. It indicates that a predetermined icon 862 formed in 860 is in close proximity. The icon 862 may be formed adjacent to the right end of the address input window 863.

As such, when the input medium 510 is in close proximity to the icon 862 for a predetermined time (for example, 1 second) or more, as illustrated in FIG. 17B, the controller 180 identifies the proximity touch operation. One or more web address lists 880 recently accessed on the touch screen 500 may be temporarily displayed. The web address list 880 may be formed adjacent to the bottom of the address input window 863.

The icon 862 illustrated in FIG. 17A corresponds to a parent object, and the web address list 880 displayed on the touch screen 500 by a proximity touch of the icon 862 is the icon 862. Corresponds to the child object for).

As such, when the web address list 880 is temporarily displayed on the touch screen 500, the input medium 510 is moved to a proximal position, and thus any one of web addresses included in the web address list 880. When directly touching, the controller 180 may identify the direct touch operation and display the web page corresponding to the directly touched web address in the web browser 860.

On the other hand, as shown in FIG. 17B, a web address included in the web address list 880 is included in the web address list 880 while the web address list 880 is temporarily displayed on the touch screen 500. When the touch screen 500 is out of the touch recognition effective distance without directly touching any one of the above, the controller 180 may display the web address list on the touch screen 500 as illustrated in FIG. 17A. 880 may be removed.

18A to 18B illustrate a graphic user interface provided on a touch screen during a close touch operation of an input medium according to a tenth embodiment of the present invention.

As shown in FIGS. 18A and 18B, first and second web page movement icons 864 and 865 may be formed in the web browser 860.

The first webpage move icon 864 is currently displayed on the touch screen 500 when an input medium (eg, a user's finger) 510 directly touches the first webpage move icon 864. Provides the function to display the webpage last visited before the displayed webpage. The second webpage move icon 865 is viewed before the input medium 510 directly touches the second webpage move icon 865 before executing the function of the first webpage move icon 864. It provides a function of displaying the web page on the touch screen 500 again.

On the other hand, according to the present invention, when the input medium 510 touches the first and second web page moving icons 864 and 865 in close proximity, the preview image may be provided as follows.

In FIG. 18A, reference numeral 512 denotes a proximity touch of the first webpage moving icon 864 displayed on the touch screen 500 by the input medium 510 within a touch recognition effective distance of the touch screen 500. It is shown.

As such, when the input medium 510 comes in close contact with the first webpage moving icon 864 for a predetermined time (for example, 1 second) or more, as illustrated in FIG. 18B, the controller 180 may perform A preview image 881 in which the webpage visited last before the webpage currently displayed on the touch screen 500 is identified on the first webpage moving icon 864 by identifying the proximity touch operation. ) Can be displayed temporarily. That is, when the first web page movement icon 864 is in close touch, a preview function may be provided through the preview image 881. On the other hand, when the input medium 510 touches the second webpage moving icon 865 in close proximity, the controller 180 may have viewed the web before executing the function of the first webpage moving icon 865. A preview image (not shown) in which the page is reduced may be temporarily displayed on the second webpage moving icon 865.

Here, the first webpage move icon 864 corresponds to a higher object, and the preview image 881 displayed on the touch screen 500 by a proximity touch of the first webpage move icon 864. ) Corresponds to a sub-object of the first web page move icon 864.

As such, when the input medium 510 is moved in a proximate position while the preview image 881 is temporarily displayed on the touch screen 500, the touch screen directly touches the preview image 881. 180, the web page corresponding to the directly touched preview image 881 may be enlarged and displayed on the web browser 860 by identifying the direct touch operation.

On the other hand, as shown in FIG. 18B, the input medium 510 directly touches the preview image 881 while the preview image 881 is temporarily displayed on the touch screen 500. If the touch screen 500 is out of the touch recognition effective distance without this, the controller 180 can remove the preview image 881 on the touch screen 500 as shown in FIG. 18A. .

The above-described portable terminal having a proximity touch recognition function and a method for providing a graphic user interface using the same are not limited to the configuration and method of the above-described embodiments, but the embodiments may be modified in various ways. All or some of the embodiments may be selectively combined. For example, in the above description, a configuration in which only the selected object is enlarged when the proximity touch is described has been described. However, another display method may be provided in consideration of the user's convenience.

Since the proximity touch and the direct touch described above should be expected to be made by an input medium that is too large compared to the object being displayed on the portable terminal such as the user's finger, even if a method such as an enlarged display is provided during the proximity touch, In addition, the objects must be over a certain size for easy operation. This is due to a problem that it is difficult to select adjacent objects when the size is too small and there is a narrow gap between them.

19 to 20 illustrate a concept of a mobile terminal for displaying a predetermined object. Referring to FIG. 19, a plurality of objects that can be selected or changed in magnification exist on the touch screen.

Of these, objects that are separated from each other, such as ①, can be used conveniently by applying the same method as the above-mentioned close-up touch, but when a plurality of objects are located close to each other, such as ②, Difficult to choose For example, if the user wants to select the right object from the upper left ② where two objects are in close proximity, the proximity touch is performed by the above-described method, and only one object close to the input medium is enlarged and displayed. In this case, the right object may be selected due to the correct proximity touch of the user. However, when the left object is selected due to a mistake or the like, the left object is enlarged and displayed so that the right object is hidden. In this state, since the selection of the right object is difficult, it is necessary to release the proximity touch and try again. Even if the enlarged object is displayed in a different position so that it is not obscured by the input medium (in this case, the object on the right that is to be selected by the enlarged left object is also not hidden), the user may basically narrow the gap. It is necessary to move the input medium finely in order to select the right object out of ② in the upper left corner. This process is almost impossible in view of the reality of use of the mobile terminal, which is used in a mobile state where at least a fine movement exists. Therefore, in order to apply the above-described embodiment, the object size and spacing should be adjusted and displayed to the extent that each object can be easily distinguished and selected using a user's finger or the like as an input medium. However, since this requires an enlargement of the entire object, it means that all objects that are easy to use should be displayed separately on one screen (since they cannot be displayed on one screen). That is, in such a case, the user needs additional work such as moving the screen to indicate an object that is not displayed on the screen.

In order to solve this problem, the portable terminal according to the following embodiment includes a touch screen 10 that generates different touch input signals according to a proximity touch or direct touch operation of an input medium and a plurality of objects within a predetermined range from the input medium ( And a control unit 20 for changing the magnification according to the proximity touch or direct touch operation of the input medium.

Since the touch screen 10 is the same as the above description, a description thereof will be omitted, and the controller 20 will be described by changing the magnification of the plurality of objects according to a proximity touch or a direct touch operation.

In this case, referring to several things to consider, it is a question of how many objects are selected on a touch screen on which an object capable of changing or selecting a plurality of magnifications is displayed, which multiplies all the objects within a predetermined range from the input medium. A method of changing and displaying the display. Even if the input medium is within a predetermined range, when the number exceeds the reference value, only a predetermined number of objects close to the center of the input medium may be displayed.

In view of this, two or more objects located within a predetermined range from the input medium are displayed after being changed in magnification. Generally, the change of magnification will be a concept of magnification.

Next, the question is how to determine a certain range from the input medium. The predetermined range should include at least a range that is expected to be selected when the user instructs a proximity object or a direct touch by indicating a certain object through a predetermined input medium. Therefore, the range should be appropriately set based on the point of the touch screen that recognizes the recognition of the input medium at the shortest distance, and the nature of the object currently being displayed should be considered. For example, when an object is displayed as a list such as an option menu, the left and right sides of the touch screen are not important, and the range should be determined based on the upper and lower ranges.

Next, the change of the magnification of the plurality of selected objects is performed. In general, the change of the magnification may be enlarged, but may be reduced in some cases.

Finally, consideration should be given to the touch method. In general, it is preferable to enlarge and display the selected plurality of objects through the proximity touch and then select a desired object from the selected plurality of objects through the direct touch. However, in consideration of the characteristics of the device and the user's manipulation ability, It is also expected that operation such as movement is difficult for the user. Accordingly, a method of enlarging and displaying a plurality of selected objects by direct touch and selecting a desired object through direct touch release (touch release), repeated touch in the current state, and the like may be considered.

Of course, the control unit should be configured to return the selected plurality of objects to the original magnification when the proximity touch or the direct touch by the input medium is released.

FIG. 22 illustrates an example in which such a plurality of selected objects are enlarged (magnified) and displayed.

Unlike those described with reference to FIGS. 19 to 20, both objects 2 located at the upper left are enlarged and displayed. By enlarging and displaying the selected plurality of objects as described above, the user can easily identify when the size of the basic object is small, and the user can easily identify and select a desired object among the enlarged selected plurality of objects. Referring to FIG. 22, it can be seen that the center points of the two objects to be enlarged are also moved in accordance with the enlargement magnification so that the intervals are widened. The user selects a desired object by moving the input medium by the widened interval. It can be facilitated. Of course, in this case, it is necessary for the user to distinguish the movement from the object to the other position rather than the movement of the object within the plurality of selected objects, which is a proximity touch, that is, a proximity distance between the input medium and the touch screen. This can be solved by responding differently. In other words, the proximity touch can be set to a plurality of stages according to the distance, and the resolution can be solved by making the movement within the selected plurality of objects and the movement to other positions respectively correspond to each stage.

Of course, since all objects in the plurality of selected objects are enlarged, even if the movement in the plurality of selected objects is determined according to the operation at the basic magnification before the enlargement, the selection will be more convenient.

On the other hand, when the plurality of selected objects are all displayed at the same magnification, when the distinction of each object is clear, the user may induce selection by recognizing that the user has positioned the input medium at the correct position. Considering the screen of it would never be desirable. Therefore, it is preferable to distinguish the object having the shortest distance from the input medium within the plurality of selected objects from other selected plurality of objects.

For example, the object located at the shortest distance from the input medium may be displayed in a larger manner than the other selected plurality of objects, or the selected plurality of objects other than the object located at the shortest distance may be reduced.

In the former case, when the selected object is enlarged and displayed by default, the object of the shortest distance can be enlarged further, so that the user can clearly indicate what the input device is currently pointing to, and in the latter case, the shortest distance. Selecting Other Objects By displaying a plurality of objects smaller than other objects, the input device indicates an object. In this case, the shortest object may be enlarged and displayed, but a relative enlargement effect may be obtained through a reduced display of a plurality of nearby selected objects, and thus may not be enlarged.

The controller may adjust the magnification of the selected plurality of object displays differently according to the degree of proximity touch of the input medium. For example, the controller may divide the magnification into steps as shown in FIG. 23.

A to the distance from the start of the recognition of the proximity touch to a certain distance, C, the section that is difficult for the user to adjust the section of the proximity touch and direct touch to C, between the A and C sections to B, 1.5 times in the A section 1st magnification such as magnification, and 2nd magnification such as 2x magnification in section B. As such, by varying the magnification according to the proximity touch distance, it is possible to provide convenience to the user. The section C is a section in which it is difficult for a user to distinguish between a proximity touch and a direct touch, and the section C generally corresponds to a section in which the user may be directly connected by a direct touch when attempting a proximity touch. The processing for the C section may be performed by the second touch with a direct touch or as an extension of the B section.

Of course, in a special case, it may be reduced and displayed as it approaches, which may be set according to the characteristics of the corresponding object or by changing an option by a user.

Meanwhile, in the above description, the center of the selected plurality of objects displayed at the magnification changed according to the proximity touch or the direct touch is moved in accordance with the magnification change when enlarged, that is, not only the size of the object itself but also the distance between the objects is adjusted according to the magnification. Explained. In this case, as mentioned earlier, an additional discrimination process is required to determine whether the movement of the input medium after the display of the selected plurality of objects is a movement inside the selected plurality of objects or moves to another position. Of course, such a process may not cause any inconvenience to the user, but it may not exclude the case of causing confusion by a difference between the moving distances between objects at the basic magnification.

Accordingly, as shown in FIG. 24, a method of changing only the magnification of the object itself and expanding the distance D between objects in the same manner as the basic magnification may be considered. In other words, the center of each of the selected plurality of objects is treated in the same manner as before the magnification change (fixed center), and the user's convenience can be provided by providing the same conditions as before the magnification change for the user's operation such as dragging. Of course, in this case, there may be a problem in which the enlarged objects overlap each other, and the problem of the inconvenience of the fine distance adjustment mentioned above remains, so that the center moving method and the fixing method may be appropriately combined. . In the former case, the shortest distance from the input medium can be solved by placing the object at the top. In the latter case, the center movement method and the center fixing method can be selected by the user's operation. The solution can be solved by finding a means to select immediately when using a service on an object.

That is, when the selection of the center movement method and the center fixed method can be selected only through the option menu, the user may have inconvenience in using the setting menu and using the service again in order to set it according to the situation while using the service. In this case, it is desirable to be able to select immediately while using the current service. For example, the center fixed method may be executed when dragging after a basic proximity touch, and the center movement method may be executed when another finger is touched in proximity with the other touch. When a finger is used as an input medium, it is common to use an index finger. When a proximity touch by a thumb that is easy to additionally touch the touch when the index finger is touched is additionally recognized, the center movement method may be executed. For reference, the center movement method is preferably limited to the movement in the selected plurality of objects that are already selected and changed in magnification.

Next, a case in which the plurality of selected objects are covered by the input medium will be described.

When a predetermined object is selected among objects being displayed through an input medium such as a finger, a plurality of objects (selected plurality of objects) within a predetermined range of the input medium are changed and displayed according to the above embodiment. In general, when considering a small size portable terminal, the magnification change will be enlarged. The enlarged display position of the plurality of selected objects may generally be the center of the entire selection plurality of objects as the shortest distance point from the input medium. In this case, the selection plurality of objects may be covered by the input medium. In order to solve the above-mentioned occlusion problem, in order to select a certain object, a proximity touch or a direct touch below a certain distance, and the controller which recognizes the above object may be recognized and processed as selecting the object above the predetermined distance. Such a method adds to the difficulty of the operation to the user and is therefore not preferable. Accordingly, there is a need for a method for allowing a user to select a desired object with a touch on a location where the object exists, while preventing the object selected by the touch from being blocked by the input medium. To this end, in the embodiment illustrated in FIG. 25, when the plurality of selected objects are enlarged due to the proximity touch or the direct touch, the controller is configured to position the center of the selected plurality of objects at a distance separated from the position before the proximity or direct touch. . That is, the entire display of the plurality of selected objects is displayed at a position spaced from the original position by a predetermined distance. In general, since the touch by the input medium covers the downward direction from the touch point, the movement of the center is upward from the touch point. desirable. Of course, the movement of the center of the whole of the plurality of selection objects (which must be distinguished from the center of each of the plurality of objects of selection) should be returned to its original state when the proximity touch or the direct touch of the input medium is released.

FIG. 26 illustrates another preferred embodiment of the present invention, wherein a touch screen generates different touch input signals according to a proximity touch or direct touch operation of an input medium, a menu list displayed on the touch screen, and the input medium. The use state of a portable terminal including a control unit which enlarges and displays a plurality of menus (selection menu objects) within a predetermined range according to a proximity touch or a direct touch operation of the input medium is shown.

The plurality of objects of the previous embodiment is set as a predetermined menu list, and the menu list may be various examples. For example, the menu list may be any one of an option browser, a subway map, a navigation map, a web browser explorer, and a file browser.

FIG. 26 illustrates an option browser as a menu list. When a user's proximity or direct touch indicates' 3 Call history ',' 2 Address book 'and' 2 Address book 'and' that exist within a predetermined range of the input medium are shown. 4 Change and display Orange Music '. That is, the above three menus become selection menu objects, and differentiate them from other menu lists in magnification.

Conventionally, the menu list is expanded as compared to FIG. 26 in consideration of the size of the input medium, etc. As shown in FIG. 27, in this case, it is difficult to display all the menu list on one screen. It was provided in the form of sliding by touching the arrow at the bottom of the. However, such a separation of the menu list is inconvenient to use, so basically it is necessary to display one menu list on one screen, which can be solved through this embodiment.

The size of the menu list to be displayed on one screen (of course, it should satisfy the size that can be recognized by the eye, and if the menu list is too large to recognize when displaying on one screen, it is preferable to divide the menu list. To display it. When the menu list has a size that can be recognized by the eye, but it is difficult to select a desired list through an input medium such as a finger, according to the present embodiment, a menu item located at the shortest distance of the selection menu object-the input medium In the object and the shortest distance menu, all of the menu objects existing within a predetermined range are displayed by changing the magnification (generally enlarging), and the shortest distance menu object is displayed larger than other selection menu objects.

Through this, the user can check what is the menu object currently instructed by the user, and can easily select the desired object through the touch movement. When the distance is narrow when moving to another menu object through the touch movement, minute touch movement is difficult. Therefore, as described above, the touch screen corresponding to the enlarged size of the selected menu object can be selected. It is preferable.

That is, when the control unit recognizes an additional input medium other than the input medium, the movement of the input medium may be treated as a movement in the selection menu object.

For example, when the user confirms that the menu object selected by the user is '3 Call history' through FIG. 26 and then wants to move to '4 Orange music', the user wants to move to '4 Orange music'. Incorrect movement may indicate '5 Orange World' as shown in FIG. In this case, since the user may feel inconvenient to select a menu with more attention, it is preferable to allow the user to touch move to '4 Orange music' while being enlarged and displayed as the selection menu object in FIG. 26.

In FIG. 26, the user shows a state in which a touch is made around '3 call history', and as a selection menu object, '2 Address book' and '4 Orange music' are also partially enlarged and displayed. In this state, when the thumb is additionally touched to move the touch (drag), it is converted into the movement in the selection menu object shown in FIG. 26, so that '4 Orange music' can be easily selected. Of course, even when moving in the selection menu object, it is preferable to make the menu object of the shortest distance with the index finger as the basic input medium to be enlarged the most, so that the user is aware of which menu object is currently instructed. Shown in

If you add a thumb and move, or drag, only movement within the selection menu object, only the menu items '2 Address book', '3 Call history', and '4 Orange music' are moved. . Since only the above three menus are instructed even when the display area of the selection menu object is exceeded, for example, even when dragged to '6 Games & Apps' in FIG. Is treated as. In this state, if you release your thumb, a new selection menu centered on '6 Games & Apps' is displayed.

In this manner, the user can easily select the desired menu object by instructing the index finger to display the desired menu object as the selected menu object on the small size of the menu list, and then moving with the addition of the thumb.

The index finger and thumb described above may be moved together, or the thumb may be fixed and the index finger may be moved to allow selection. Alternative applications are also possible. For example, when using a mobile terminal, one hand is held for a touch and a touch is performed with the other. Therefore, the thumb of the held hand may be used as shown in FIG. 30. In this case, when the user wants to move within the selection menu object, the desired thumb can be achieved by touching the thumb of the hand holding the mobile terminal close to or directly on the touch screen. In other words, when the input of another input medium is recognized while the input of the basic input medium used for the menu selection is continued, the processing is performed as a movement in the selection menu object.

It should be noted that the above description is advantageous when the entire selection menu object is changed in magnification, that is, when the distance between the selection menu objects is also changed in magnification.

When the distance between each menu object constituting the menu list is so easily selectable by the user, the user may achieve a desired degree of enlargement and display for the user's convenience. That is, in this case, the movement in the selection menu object is halved. However, since the size of the menu list is generally different for each menu list, it would be desirable to provide a move function within the selected menu object.

31 shows a case where a subway route map is presented as a menu list. Subway maps are generally out of the reach of the eye if they are displayed on the screen of a mobile terminal. Therefore, the display is divided into several zones so that the eyes can be recognized. Nevertheless, the size of each station is inevitably displayed small.

At this time, in order to use the service associated with each station, for example, distance between stations, travel time between stations, and searching for food spots around the station, each station should be easily selectable. Conventionally, in order to solve the difficulty of selecting a station, when a certain area is touched in close proximity or directly, the entire area is enlarged and displayed. However, in this case, if you want to select a different station to go back to the basic screen to take a method again, such a method would have experienced a considerable inconvenience.

In FIG. 31, a desired station can be conveniently selected from a small subway map by expanding and displaying not only the station of the shortest distance in close proximity or direct touch but also a station within a certain range. The user who wants to select the Sindorim station touches or touches the Sindorim station directly through the input medium on the unexpanded basic subway map. However, due to the small size of the basic subway map, they could not touch Sindorim Station accurately but touched nearby Guro Station. The control unit recognizes the input medium, and displays, as a selection menu object, both the Guro station, the menu object existing at the shortest distance from the input medium, and the Sindorim station and Daelim station, the menu objects existing within a predetermined range from the input medium, as a selection menu object. . The display may be a display using an entire screen or a display using a partial screen. When the touch of the input medium is released, the display is configured to return to the original subway route, thereby eliminating inconvenience in use as before.

The Guro Station, Sindorim Station, and Daelim Station selected as the selection menu objects are displayed by changing the magnification, and generally enlarged and displaying the Guro Station of the shortest distance from the input medium. The user recognizes that the current selection is the Guro Station. You can easily choose Sindorim Station that was originally intended. When the selection menu object is displayed through the entire screen, by moving the input medium in an enlarged state, the Sindorim station can be easily selected. When the selection menu object is displayed through some screens, the user moves to a station other than the selection menu object. A crash can occur. That is, when the user moves the input medium to the position of Sindorim station due to the enlarged magnification when the selected menu object is enlarged and displayed at the current position, the selected menu object is selected whether the Shindorim station in the enlarged display menu object is selected or not. It is necessary to distinguish whether or not Singil Station is selected from the route map. This can be solved by introducing an example of applying the above option browser as a menu list. In other words, if the additional input medium is recognized, it can be recognized as a movement in the selection menu object, and if not, it can be recognized as a movement on the subway map of the original magnification.

Of course, when the magnification of the subway map is displayed on the basis of the high magnification, it is not difficult to distinguish between the stations, and the center of each station in the subway map (the distance between the stations is fixed) is left unchanged. Can provide convenience. When an overlapping portion occurs due to the enlargement of each of the selection menu objects, it is preferable to place the object having the shortest distance on the input medium at the top.

On the other hand, when the menu object is composed of images and texts, such as subway maps, only one of the images or texts can be enlarged, and both images and texts can be enlarged. Could be.

In the case of the subway map, each menu object is small, unlike the option browser. Therefore, since the selection menu object may be covered by the input medium, when the selection menu object is enlarged due to the proximity touch or the direct touch, the center of the entire selection plurality of objects is spaced a certain distance from the position before the proximity or direct touch. It can also be located.

That is, in the case of FIG. 31, the selection menu objects Guro Station, Sindorim Station, and Daelim Station are displayed at other positions, such as the upper left, instead of the corresponding positions in the original basic subway map, thereby preventing obstruction by the input medium. In this case, the area displaying the selection menu object may be allocated to a predetermined area of the screen as illustrated in FIG. 32. In this state, movement within the enlarged selection menu object may be performed through the recognition of additional input means as described above, and movement of only the basic input medium may correspond to the subway route map of the basic magnification. That is, when Guro Station, Sindorim Station, and Daelim Station are selected as the selection menu objects in the subway route map with the basic magnification as shown in FIG. 32, when the additional input medium is recognized, the selection menu object is fixed. In this case, two methods for moving within the selection menu object may be considered. When the selection menu object is fixed due to an additional input medium such as a thumb other than the basic input medium such as the index finger, the index finger, which is the basic input medium, is released from its original position, and the enlarged selection menu object is displayed on the upper left. It is also possible to select a desired station by moving to the area, and without touching the index finger from the original position, the desired station is intuitively touched by the direction and distance S between each station, which is a selection menu object displayed on the upper left as shown in FIG. You can also choose. Of course, the selected station must be displayed to be the largest among the selection menu objects so that it can be confirmed.

34 illustrates a case where a navigation map is presented as a menu list. In the case of a navigation map, the choice of the point of interest is important. Previously, this was for the inconvenient method of inputting an address directly, which was inconvenient when moving, especially while driving, and also included the possibility of a safety accident. Therefore, setting the destination through the selection menu has become a very important problem. However, the specific detailed area eventually requires a user's direct address input, so a method for solving the problem is required. In the case of a portable device such as a mobile terminal, which is a navigation map display means, the display of the spot displayed due to the small size of the screen is also small. To this end, there may be a method of selecting through direct touch after enlarging through a proximity touch or the like, but if the enlarged point is not a desired point, the user must reconfirm through a small screen. Accordingly, in the present embodiment, all points within a predetermined range of the input medium are enlarged and displayed, so that even in case of an o-touch caused by some mistake of the user, a desired point nearby is displayed. By easily identifying the desired point through the enlarged display and modifying the touch, it is easy to select the desired point.

Of course, even if the menu list is a navigation map, the above-described exemplary embodiments of the option browser and the subway map can be applied.

35 shows a case where a web browser is presented as a menu list. In detail, a state in which a country menu is displayed at a narrow interval among menus of a web browser is shown, but the interval is smaller than that of an input medium such as a finger. Therefore, when the user wants to select 'China', 'Espana' is selected because it is difficult to select correctly. In the present embodiment, besides 'Espana' which is enlarged and displayed through the proximity touch, 'Deutschland' and 'France' existing within a predetermined range are also enlarged and displayed. Of course, in order to indicate that the currently selected menu object is 'Espana', the 'Espana' is preferably displayed larger than the other two countries.

In the present exemplary embodiment, other nearby menu objects are hidden due to the enlarged selection menu object. Thus, 'China', which was originally intended, is not hidden and displayed by the enlarged selection menu object. However, in the case of the country menu, since it is generally listed in alphabetical order, the user can recognize that there is 'China' in the hidden menu, so that the user can select 'China' through the proximity touch movement. However, since menu presentation based on the user's experience and knowledge can be inconvenient, it is desirable to take some alternatives.

This alternative is also applicable to the solution to the problem of obscuring the neighboring menu object due to the selection menu object not mentioned in the previous embodiment.

When each object is an array of strings as illustrated in FIG. 35, there may be a method of moving a menu object positioned below the enlarged selection menu object as shown in FIG. 36 by the enlarged T of the selection menu object. In other words, by moving the center of the adjacent menu object, there is no menu object that is hidden. However, such a method is difficult to apply when each menu object such as a subway map or a navigation map includes an image associated with the entire image. Next, as mentioned in the previous subway map, it is possible to fix the selection menu object in a certain area of the screen and display the same. In addition, there may be a method of displaying a distance from the original position by using a leader line, and the selection of this method should be adjusted according to the nature of the menu list and the user's taste. Of course, when the touch by the input medium is released, it must be returned to its original state.

36 shows a case where a file browser is presented as a menu list. In the case of a file browser, a name of a folder or a file is generally displayed in a small size, which makes the user uncomfortable. Accordingly, a method of enlarging and displaying only the object of the shortest distance with the input medium in proximity or direct touch by the input medium has been proposed, but within a predetermined range with the input medium for convenient selection of the user and provision of more information. It is preferable to also enlarge and display the file. In other words, by enlarging and displaying all file objects within a certain range from the input medium in proximity or direct touch, it is possible to provide more information to the user and facilitate selection. In this way, even if more files are displayed on one screen, there is no big problem in selection, thereby helping to improve the reliability of the product.

However, as shown in FIG. 37, when the distance between each file object is narrow, a solution of the problem of occluding the neighboring file object due to the enlarged selection menu object, a countermeasure for moving the menu object within the expanded selection menu object, and the like. This is required, and this is applicable to the above-described example as it is.
