An order of precedence of a program whose processing screen is displayed in the main display area 21 is set in accordance with a use state such as a touch operation and an elapse of a predetermined time, and a display width of the selection icon displayed on the task bar 30 is adjusted on the basis of the set order of precedence and a weight W by means of icon display width adjusting processing.

Description

  The present invention relates to a mobile terminal in which an icon for selecting a started program is displayed on a display screen.

  Generally, when an application is started on a terminal, the processing screen of the application is displayed on at least a part of the display screen, and an icon for selecting the started application separately from other applications and holders is displayed. Appears in the taskbar at the bottom of the screen. In particular, when a plurality of applications are activated, each icon is displayed after being uniformly adjusted to a display width that can be displayed on the task bar.

  However, when the display screen is small like a portable terminal, the area that can be displayed on the task bar is narrowed. Therefore, when several applications are activated, the display width of the icon displayed in the task bar is reduced. Thus, when the icon display width is reduced, there is a problem that it is difficult to perform a tap operation on the screen for a desired icon. Moreover, since the characters that can be displayed on the icon are also reduced, there is a problem that it is difficult to recognize which icon corresponds to the application to be selected.

  Therefore, for example, in the sheet tab display control apparatus shown in Patent Document 1 below, the sheet length is adjusted to display as many characters as specified in the sheet tab, but not as much as the task bar. It is devised to display the sheet. For example, when a single sheet tab cannot be displayed, a plurality of sheet tabs are displayed.

JP 2009-059146 A

  However, since many icons are to be displayed in the taskbar because many programs have been started, if a plurality of taskbars are displayed as described above, the processing of the started program is displayed on a small display screen like a mobile terminal. There is a problem that the display area for displaying the screen is narrowed and the usability is deteriorated.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to select a program on which a processing screen is displayed without narrowing a display area for displaying the processing screen of the program. It is an object of the present invention to provide a portable terminal that can easily select and display the icon.

In order to achieve the above object, a first aspect of the present invention provides a portable terminal (10) including a display unit (13) and a control unit (12) for controlling display contents on a display screen (20) of the display unit. The display area of the display screen includes a first display area (21) in which one or more processing screens (23a to 23d) of the activated program can be displayed, and one direction narrower than the first display area. A second display area (31a to 31d) for selecting a program (31a to 31d) that is a long strip-shaped area and is displayed along the one direction. 30), and the control unit displays the icons corresponding to one or more programs in which the processing screen is displayed in the first display area so as to occupy the entire second display area. Then In addition, the icon display means (12) for excluding the icon corresponding to the terminated program from the second display area, and the priority of the program in which the processing screen is displayed in the first display area according to the use situation A priority order setting means (12) to be set, and a display for adjusting the display width in one direction of the icon displayed in the second display area based on the priority order set by the priority order setting means Width adjusting means (12).
In addition, the code | symbol in each said parenthesis shows the correspondence with the specific means as described in embodiment mentioned later.

  In the invention of claim 1, the icon display means displays icons corresponding to one or more programs whose processing screens are displayed in the first display area so as to occupy the entire second display area, The icon corresponding to the finished program is excluded from the second display area. Then, the priority order of the program whose processing screen is displayed in the first display area is set according to the use status by the priority order setting means, and the display width of the icon displayed in the second display area is the priority order setting means. Is adjusted by the display width adjusting means on the basis of the priority order set by.

As a result, the display width of an icon having a high priority, that is, an icon that is highly likely to be selected, is largely adjusted as compared with other icons having a low priority, so that an icon that is highly likely to be selected is selected. Can be easily displayed. In particular, since the display width of other low priority icons is relatively small, the size of the first display area and the second display area in the display screen does not change.
Therefore, it is possible to easily select an icon for selecting the program on which the processing screen is displayed without narrowing the first display area for displaying the processing screen of the program.

  In the invention of claim 2, when a plurality of processing screens are displayed in the first display area, if any icon displayed in the second display area is selected, the priority order setting means selects this icon. The priority of the program corresponding to the selected icon is set highest, and the priority of the program corresponding to the other icon is set low.

  Since the icon of the selected program is an icon that is highly likely to be selected in the future, it is possible to select the icon without reducing the first display area by setting the highest priority of the selected program. It is possible to reliably display an icon that is likely to be selected.

  In the invention of claim 3, the priority is not set immediately after the program is started, and when any of the icons displayed in the second display area is selected, the program in which the priority is not set (hereinafter referred to as the program) , Which is referred to as an unset program) is set to be higher next to the program corresponding to the selected icon.

  Immediately after startup, the priority order of the program cannot be accurately grasped, and therefore setting the wrong priority order can be suppressed by not setting the priority order. After that, when one of the other programs is selected and its priority is set highest, the unset program among the remaining programs becomes the program with the shortest time since startup. By setting the priority of the unset program so as to be higher next to the selected program, it is possible to realize the setting of the priority according to the use situation.

  In the invention of claim 4, when there is a program for which the priority order is not set after the lapse of a predetermined time, the priority order of the unset program is set to the highest. When setting the priority of an unset program that has not been set immediately after startup after a predetermined time has elapsed, the unset program becomes the program with the shortest time since startup. Therefore, by setting the priority of the unset program to the highest level, the priority of the unset program can be set according to the usage status.

  In the invention of claim 5, when a plurality of icons are displayed in the second display area, the display width of the icons corresponding to other programs except the program set with the highest priority is gradually reduced with time. The display width of the icon corresponding to the program set with the highest priority is gradually adjusted in accordance with the display width thus adjusted.

  As a result, the display width of an icon with a high priority, that is, an icon that is highly likely to be selected is gradually adjusted with time, so that an icon that is likely to be selected can be displayed more easily. be able to.

  According to the sixth aspect of the present invention, the amount of change for gradually reducing the icon display width with time can be set to a desired value by the amount of change setting means. For example, in a work environment where many programs are used one after another in a short time, the amount of change is reduced, and the amount of change is set in accordance with an assumed icon selection state. Icon display can be realized.

  According to the seventh aspect of the present invention, when the icon corresponding to the display width determined to be equal to or smaller than the predetermined threshold by the determination unit is removed from the second display area by the removal unit, the enlarged display indicating the presence of the icon removed by the removal unit. The icons are arranged in one direction along with the other icons in the second display area so as to be selectable. When the enlarged display icon is selected, the icon displayed in the second display area is removed, and the icon removed by the removing unit is displayed in the second display area so as to be selectable.

  An icon with a low selection frequency has a display width that gradually decreases with time. If the display width becomes too small, it becomes difficult to select the icon. Therefore, instead of one or more icons (hereinafter referred to as low frequency icons) whose display width has become smaller than a predetermined threshold, an enlarged display icon is displayed in a part of the second display area, and this low frequency icon is displayed. Is selected, the low-frequency icon is displayed instead of the icon already displayed in the second display area in response to the selection of the enlarged display icon. Thereby, even an icon with a low selection frequency can be easily displayed.

  In the invention of claim 8, since the display width value of the enlarged display icon is set to be larger than the predetermined threshold value, the enlarged display icon can be easily displayed in the second display area.

  According to the ninth aspect of the present invention, when the icon displayed in the second display area is selected by selecting the enlarged display icon, the priority order of the program corresponding to the icon is the highest by the priority order setting means. Set high.

  Even if the program corresponds to the icon removed from the second display area because the selection frequency is low, the icon selected through the selection of the enlarged display icon is an icon that is highly likely to be selected in the future. Therefore, by setting the highest priority of the selected program, it is possible to reliably display an icon that is highly likely to be selected.

  In the invention of claim 10, since the display unit is composed of a touch panel provided with an input unit for selecting an icon on the outer surface part, even if the icon is selected by touching the display screen like the touch panel, the second part is used. An icon displayed in the display area can be easily selected.

Hereinafter, a mobile terminal according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing a mobile terminal 10 according to the first embodiment. FIG. 2 is a block diagram showing an electrical configuration of the mobile terminal 10.
A mobile terminal 10 shown in FIG. 1 is a mobile terminal that realizes an information processing function corresponding to an application by executing one of a plurality of application programs (hereinafter, also simply referred to as an application). The mobile terminal 10 includes a display device 13 having a display screen 20 arranged so as to occupy most of the front surface of the housing 11, and a control unit 12 that controls the overall control of the mobile terminal 10 including the display device 13. It is equipped with.

  The display device 13 is composed of a touch panel provided with an input unit on the outer surface. When the user presses the display screen 20 with a touch pen or the like, information corresponding to the pressed area is input to the control unit 12. It is configured to be. Also, a plurality of operation buttons 14 a constituting the operation unit 14 are provided as input means different from the touch panel near the lower edge of the display screen 20 on the front surface of the housing 11.

Next, the electrical configuration of the mobile terminal 10 will be described.
As shown in FIG. 2, the display device 13 and the operation unit 14 described above are connected to the control unit 12, and a memory 15, a communication unit 16, a battery 17, and the like are connected to each other. The control unit 12 is a microcomputer capable of controlling the entire mobile terminal 10 and includes a CPU, a system bus, an input / output interface, and the like, and has an information processing function for executing an operating system and a predetermined application. Various input / output devices (peripheral devices) such as the display device 13 and the operation unit 14 are connected to the control unit 12 through built-in input / output interfaces.

  The display device 13 is controlled by an icon display process (to be described later) by the control unit 12 and configured to be able to display a processing screen at the time of application activation, information corresponding to a touch operation on the touch panel, and the like on the display screen 20. Yes. The display screen 20 can display a main display area 21 that can display one or more processing screens of the activated program, and a selection icon for selecting an application on which the processing screen is displayed. It is divided into a task bar 30 as a display area. The display device 13 may correspond to an example of a “display unit” described in the claims. The main display area 21 may correspond to an example of a “first display area” described in the claims, and the task bar 30 may correspond to an example of a “second display area” described in the claims. .

  In the main display area 21, a start icon that can start a predetermined application by a touch operation is displayed. In the main display area 21 illustrated in FIG. 1, an activation icon 22a for activating a first application program (hereinafter referred to as APL1) and an activation icon for activating a second application program (hereinafter referred to as APL2). Touch operation is possible for the icon 22b, a start icon 22c for starting a third application program (hereinafter referred to as APL3), and a start icon 22d for starting a fourth application program (hereinafter referred to as APL4). Is displayed. Further, in the main display area 21 illustrated in FIG. 1, the APL2 processing screen 23b is displayed in the top window among the APL1 processing screen 23a and the APL2 processing screen 23b that are being activated. In this way, the processing screen is displayed on the top window, so that predetermined information can be input to the application.

  The task bar 30 is displayed as a band-like area that is narrower and longer in one direction than the main display area 21 along the lower edge of the main display area 21. In the task bar 30, when one or more of the processing screens are displayed in the main display area 21, selection icons are arranged along the one direction (hereinafter referred to as an arrangement direction) for each application. Is displayed. This selection icon is an icon that is touch-operated when a processing screen corresponding to a desired application is displayed on the top window, that is, when a desired application is selected. In the task bar 30 illustrated in FIG. 1, the selection icon 31 a and the selection icon 31 b for selecting APL 1 and APL 2 whose processing screens are displayed in the main display area 21 occupy the entire display area of the task bar 30. It is displayed.

  The operation unit 14 is configured such that a signal corresponding to the operation is input to the control unit 12 when the user operates each operation button 14a. The memory 15 is configured by a semiconductor memory such as a ROM, a RAM, a nonvolatile memory, and the like, in order to execute information input from the control unit 12 and a predetermined application (APL1 to APL4, etc.) in the control unit 12. The program is stored. The communication unit 16 is configured as an interface for performing wireless communication with an external device by a communication unit such as a wireless LAN or Bluetooth (registered trademark). The battery 17 is configured by a secondary battery (for example, a lithium ion battery) that can generate a predetermined DC voltage, and supplies power to various electrical components in the mobile terminal 10.

Next, the icon display process implemented in the control part 12 of the portable terminal 10 comprised as mentioned above is demonstrated below. The control unit 12 that performs the icon display process may correspond to an example of “icon display means” recited in the claims.
When the display screen 20 is small like the portable terminal 10, the area that can be displayed on the taskbar 30 is narrowed. Therefore, when several applications are started, the display width of the selection icon displayed on the taskbar 30 is reduced. End up. Thus, when the display width of the selection icon is reduced, it becomes difficult to perform a tap operation on the screen with respect to a desired selection icon.

  Therefore, in the icon display processing in the present embodiment, the display width of the selection icon that is highly likely to be selected is adjusted and selected so as to be larger than the selection icon that is unlikely to be selected. A selection icon that has a high possibility of being displayed is easily displayed.

  Specifically, the weight W is calculated so that the sum of the selection icons to be displayed on the task bar 30 is 1 with reference to the arrangement direction length in the area where the selection icons can be displayed on the task bar 30. The weight W is set (changed) so as to consider the possibility of selection according to the passage of time. That is, the weight W is a value corresponding to the display width of the selection icon. In addition, a priority order is set for each application for which a selection icon is displayed on the task bar 30, and the priority order is changed according to a touch operation (selection) of any selection icon or the like.

  In particular, in this embodiment, the weight W and the priority are associated with each other, and when the priority is changed, the weight W associated with each priority before the change and the weight associated with each priority after the change. The weight W is reset so that W matches. Specifically, for example, APL1 is set at the first priority and its selection icon 31a is set to weight W = 0.7, and APL2 is set at the second priority and its selection icon 31b is set to weight W = 0.3. If the selection icon 31b is touched while being set, the priority order of APL2 is changed to the first, and the weight W of the selection icon 31b is set to 0.7 in accordance with this change. Is done. In this case, the priority order of APL1 is changed to the second place, and the weight W of the selection icon 31a is set to 0.3 in accordance with this change.

  The icon display process performed in consideration of the weight W and the priority order as described above will be described with reference to the flowcharts shown in FIGS. FIG. 3 is a flowchart illustrating the flow of icon display processing in the control unit 12 according to the first embodiment. FIG. 4 is a flowchart illustrating the flow of a subroutine of the first weight setting process of FIG. FIG. 5 is a flowchart illustrating the subroutine flow of the second weight setting process of FIG. FIG. 6 is a flowchart illustrating the flow of the third weight setting process subroutine of FIG. FIG. 7 is a flowchart illustrating the flow of a subroutine of the fourth weight setting process of FIG.

  When the user turns on the mobile terminal 10 and starts up the operating system, the control unit 12 starts icon display processing. First, in the determination processing shown in step S101, it is determined whether a predetermined application has been started up. Is done. If the application has not been started (No in S101), it is determined whether or not a selection operation (touch operation) has been performed on the selection icon displayed on the task bar 30 in the determination process shown in Step S103. If the selection operation has not been performed on the selection icon (No in S103), it is determined whether or not the application is terminated in the determination process shown in step S105. If the application has not been terminated (No in S105), it is determined in the determination process shown in step S107 whether or not an elapsed time T described later is equal to or longer than a predetermined time Tth. If the elapsed time T is less than the predetermined time Tth (No in S107), the time measuring process shown in step S109 is performed, and the elapsed time T is measured. Subsequently, an icon display width adjustment process shown in step S111 is performed. In this processing, the display width of the selection icon is adjusted based on the weight W set or the like as described later, and the selection icon is displayed so as to occupy the entire display area of the task bar 30. And the process from the said step S101 is made, and the process from the said step S101 is repeated until it determines with Yes in any determination process. Note that the control unit 12 that performs the icon display width adjustment processing shown in step S111 may correspond to an example of “display width adjustment means” described in the claims.

First, a case where a predetermined application is activated will be described below.
When a predetermined application is activated by touching one of the activation icons displayed in the main display area 21 during the repetitive processing from step S101 (Yes in S101), the process is shown in step S200. A first weight setting process is performed. In the first weight setting processing subroutine, first, the weight calculation processing shown in step S201 of FIG. 4 is performed. In this process, the weight W of the selection icon corresponding to the activated application is calculated using the following equation (1). In Equation (1), N indicates the total number of applications that are activated.
W = 1 / N (1)

  Next, in the determination process shown in step S203, it is determined whether another application is activated. Here, for example, if the activation icon 22a is touched and APL1 is newly activated and no other application is activated (No in S203), the subroutine of the first weight setting process is completed. . As described above, when the first weight setting process subroutine is completed, the icon display width adjustment process shown in step S111 is performed, and the selection icon 31a corresponding to the newly activated APL1 is calculated in the weight calculation process. A display width corresponding to the weight W is displayed so as to occupy the task bar 30.

The screen transition before and after this new APL activation will be described with reference to FIG. 8A and 8B are explanatory diagrams for explaining screen transitions when APL is newly activated. FIG. 8A shows a display state before the new activation, and FIG. 8B shows a display state after the new activation.
When no application is activated, no selection icon is displayed on the task bar 30 as shown in FIG. In this display state, when the activation icon 22a is touched and APL1 is newly activated (Yes in S101), the weight calculation process calculates the weight W = 1 because N = 1 according to Equation (1). The Thereby, as shown in FIG. 8B, the selection icon 31a is displayed so as to occupy the entire display area of the task bar 30 by the icon display width adjustment processing.

  Further, in the determination process shown in step S203 described above, if another application is activated, for example, APL1 to APL3 have already been activated, and if APL4 is additionally activated, it is determined as Yes. Subsequently, in the determination process shown in step S205, it is determined whether there is any other application for which priority is not set. Note that the priority order is not set in the application immediately after startup, and is not set until a touch operation or the like is performed on any selection icon as will be described later.

Here, when all the priorities are set for APL1 to APL3 (No in S205), the weight recalculation process shown in step S207 is performed. In this process, the weight W corresponding to other applications other than the additionally activated application is recalculated using the following equation (2). In Equation (2), W1 represents the weight after change, W2 represents the weight before change, and N1 represents the number of applications that have been additionally activated.
W1 = (1− (1 / N) × N1) × W2 (2)

  When each weight W is calculated by the above equation (2), the subroutine of the first weight setting process is ended, and the icon display width adjustment process is performed. When APL4 is additionally activated as described above, each of the selection icons 31a to 31c has a display width corresponding to the weight W calculated using Expression (2), and the selection icon 31d is replaced with Expression (1). ) Is displayed on the task bar 30 so as to have a display width corresponding to the weight W calculated using the.

  The change in the weight W and the screen transition before and after the APL additional activation will be described with reference to FIGS. FIG. 9 is an explanatory diagram showing changes in the weight W before and after additional activation when there is no unset APL. 10A and 10B are explanatory diagrams for explaining screen transitions at the time of APL additional activation. FIG. 10A shows a display state before additional activation, and FIG. 10B shows a display state after additional activation.

  When the priorities and weights W of APL1 to APL3 are set as before the additional activation in FIG. 9, as shown in FIG. 10A, the main display area 21 has a processing screen 23a of APL1. Is displayed in the top window, and selection icons 31a, 31b, and 31c are displayed on the task bar 30 at a display width ratio of 0.5: 0.3: 0.2. When the activation icon 22d is touch-operated in this display state and the APL4 is additionally activated (Yes in S101), the weight W of the APL4 selection icon 31d is expressed by the above equation (1) as shown after the additional activation in FIG. Since N = 4, W is calculated as 0.25. Further, the weights W of the selection icons 31a, 31b, and 31c for APL1 to APL3 are recalculated as 0.375, 0.225, and 0.15 by the above equation (2).

  Then, the icon display width adjustment process is performed, and as shown in FIG. 10B, selection icons 31a, 31b, 31c, and 31d are displayed on the task bar 30 at 0.375: 0.225: 0.15: Displayed at a ratio of 0.25 display width.

Further, in the determination process shown in step S205 described above, if there is another application for which priority order is not set, for example, immediately after the start of APL3 and the priority order for APL3 is not set, step S209 is performed. The APL weight recalculation processing for the APL with the priority order not shown is performed. In this process, the weight W corresponding to the application whose priority is not set, in this case, the weight W of the selection icon 31c is recalculated using the above equation (1). Subsequently, the APL weight recalculation processing for which priority order has been set shown in step S211 is performed. In this process, the weight W corresponding to the application for which the priority order has been set, in this case, the weight W of the selection icons 31a and 31b is recalculated using the following equation (3). In Expression (3), N2 represents the number of applications for which priority order has not been set.
W1 = (1− (1 / N) × N2) × W2 (3)

  When each weight W is calculated using the above equation (3), the subroutine of the first weight setting process ends, the icon display width adjustment process is performed, and the weight W calculated as described above is performed. Each selection icon whose display width is adjusted is displayed on the task bar 30.

A change in the weight W before and after the APL additional activation when there is an unset application will be described with reference to FIG. FIG. 11 is an explanatory diagram showing a change in the weight W before and after additional activation when there is an unset APL.
As can be seen from FIG. 11 before the additional activation, the activation icon 22d is touched while the selection icons 31a, 31b, and 31c are displayed at a display width ratio of 0.5: 0.17: 0.33. When APL4 is additionally activated by being operated (Yes in S101), the weight W of the selection icons 31c and 31d for APL3 and 4 is N = 4 according to the above equation (1), as shown after the additional activation of FIG. Therefore, each is calculated as W = 0.25. Further, the weights W of the selection icons 31a and 31b of APL1 and APL2 are recalculated as 0.37 and 0.13 by the above equation (3).

Next, a case where the selection icon is selected (touched) will be described below.
If any of the selection icons displayed on the task bar 30 is selected by a touch operation or the like during the repetition process from step S101 (Yes in S103), the second weight setting process shown in step S300 is performed. . In the second weight setting processing subroutine, first, the determination processing shown in step S301 of FIG. 5 is performed, and it is determined whether or not the priority of the selected selection icon is first. Here, when the priority of the selected selection icon is first (Yes in S301), it is not necessary to change the weight W and the priority according to the selection operation, and the second weight setting is performed. The processing subroutine ends.

  On the other hand, when the priority of the selected selection icon is not first (No in S301), it is determined whether there is an application for which priority is not set in the determination process shown in step S303. Here, when there is no application for which priority order is not set (No in S303), priority order change processing shown in step S305 is performed. In this process, the priority of the application corresponding to the selected selection icon is set to be the highest, and other applications having higher priority than this application are set to have a lower priority. The The control unit 12 that executes the priority changing process shown in step S305 and the priority changing process shown in step S309, which will be described later, may correspond to an example of “priority setting unit” recited in the claims.

  Subsequently, a weight resetting process shown in step S307 is performed. In this process, the weight W is reset so that the weight W associated with each priority order before the change matches the weight W associated with each priority order after the change, and the second weight setting process is performed. The subroutine ends. Then, the icon display width adjustment process is performed, and each selection icon whose display width is adjusted according to the weight W set as described above is displayed on the task bar 30.

  Changes in the priority order and the weight W before and after the icon selection and the screen transition will be described with reference to FIGS. FIG. 12 is an explanatory diagram showing changes in priority and weight W before and after icon selection when there is no unset APL. 13A and 13B are explanatory diagrams for explaining screen transitions when an icon is selected. FIG. 13A shows a display state before icon selection, and FIG. 13B shows a display state after icon selection.

  When the priorities and weights W of APL1 to APL3 are set as before the icon selection in FIG. 12, as shown in FIG. 13A, the main display area 21 has a processing screen 23a of APL1. Is displayed in the top window, and selection icons 31a, 31b, and 31c are displayed on the task bar 30 at a display width ratio of 0.5: 0.3: 0.2. When the selection icon 31c is touched in this display state (Yes in S103), the priority of APL3 becomes the highest and the priority of APL1 and APL2 decreases by one as shown after the icon selection in FIG. It is done. At this time, the first priority corresponds to the weight W = 0.5, the second priority corresponds to the weight W = 0.3, and the third priority corresponds to the weight W = 0.2. Therefore, as after the icon selection of FIG. 12, the weight W of the selection icon 31c of APL3 is reset to 0.5, and the weight W of the selection icons 31a and 31b of APL1 and 2 is 0.3, respectively. Reset to 0.2.

  Then, the icon display width adjustment process is performed, and as shown in FIG. 13B, selection icons 31a, 31b, and 31c are displayed on the task bar 30 with a display width of 0.3: 0.2: 0.5. It is displayed with the ratio.

  Further, in the determination process shown in step S303 described above, if there is an application for which the priority order is not set, for example, immediately after the start of APL4 and the priority order for APL4 is not set, the priority shown in step S309 is used. A rank change process is performed. In this process, the priority of the application corresponding to the selected selection icon is set to the highest priority, and then the priority of the application with no priority set is set to the second highest, which is higher than these applications. Other applications having higher priorities are set so that their priorities are lowered by one. Then, after the weight resetting process shown in step S307 is performed and each weight W is reset, the subroutine of the second weight setting process is ended. Then, the icon display width adjustment process is performed, and each selection icon whose display width is adjusted according to the weight W set as described above is displayed on the task bar 30.

Changes in the priority and weight W before and after icon selection when there is an unset application will be described with reference to FIG. FIG. 14 is an explanatory diagram showing changes in priority and weight W before and after icon selection when there is an unset APL.
As shown before the icon selection in FIG. 14, the selection icons 31a, 31b, 31c, 31d are displayed at a display width ratio of 0.375: 0.225: 0.15: 0.25, and APL4 When the selection icon 31b is touch-operated in a state where the priority order of is not set (Yes in S103), the priority order of APL2 is set to the highest as shown after the icon selection in FIG. The priority of APL4 that has not been set is set to the second highest priority, and the priorities of APL1 and APL3 are set to the third and fourth.

  Subsequently, the weight W of the selection icons 31a, 31b, 31c, and 31d is reset to 0.225, 0.375, 0.15, and 0.25 according to the change in the priority order. Then, the icon display width adjustment process is performed, and the icons 31a, 31b, 31c, and 31d for selection are displayed on the task bar 30 with display widths with ratios corresponding to the respective weights W.

Next, the case where the application is terminated will be described below.
If a touch operation or the like for ending one of the activated applications is performed during the repeated processing from step S101 (Yes in S105), the third weight setting process shown in step S400 is performed. In the third weight setting process subroutine, first, the weight recalculation process shown in step S401 of FIG. 6 is performed. In this process, each weight W corresponding to the running application is recalculated using the following equation (4). In Equation (4), ΣWa represents the sum of the weights W excluding the weight W corresponding to the terminated application.
W1 = 1 / ΣWa × W2 (4)

  Next, the priority order changing process shown in step S403 is performed, and the priority order of the application having a lower priority order than the finished application is changed to be one higher, and the third weight setting process subroutine is finished. . Then, the icon display width adjustment process is performed, and each selection icon whose display width is adjusted according to the weight W set as described above is displayed on the task bar 30.

  Changes in the priority order and weight W before and after the end of the application and screen transitions will be described with reference to FIGS. 15 and 16. FIG. 15 is an explanatory diagram showing changes in priority and weight W before and after the end of APL. FIG. 16 is an explanatory diagram for explaining screen transition at the end of APL. FIG. 16A shows a display state before the end of APL, and FIG. 16B shows a display state after the end of APL.

  When the priorities and weights W of APL1 to APL4 are set as before the end of APL in FIG. 15, as shown in FIG. 16A, the main display area 21 has a processing screen 23b of APL2. Is displayed in the top window, and the selection icons 31a, 31b, 31c, and 31d are displayed on the task bar 30 at a display width ratio of 0.225: 0.375: 0.15: 0.25. When a touch operation or the like for ending APL4 is performed in this display state (Yes in S105), the weights W corresponding to APL1 to APL3 are set to 0.3, 0.5, 0. 2 is recalculated. After that, as shown in FIG. 15 after the end of APL, the priority order of APL1 and APL3 is changed to be one higher.

  Then, the icon display width adjustment process is performed. As shown in FIG. 16B, the selection icons 31a, 31b, and 31c are displayed on the task bar 30 with a display width of 0.3: 0.5: 0.2. It is displayed with the ratio.

Next, the case where the elapsed time T passes the predetermined time Tth will be described below.
When the elapsed time T from the start of time measurement in the time measurement process during the repetition process from step S101 exceeds a predetermined time Tth, for example, 1 minute (Yes in S107), the fourth weight shown in step S500 Setting processing is performed. In the fourth weight setting processing subroutine, first, the determination processing shown in step S501 in FIG. 7 is performed to determine whether there is an application for which priority order has not been set. If there is no application for which priority order is not set (No in S501), a weight subtraction process for subtracting the weight W other than the first priority order shown in step S507 is performed. In this process, the weights W corresponding to other applications excluding the application with the highest priority are subtracted by the change amount ΔW. In the present embodiment, the change amount ΔW is set to 0.01, for example. In the present embodiment, a predetermined lower limit is set for the weight W, and in the weight subtraction process, the weight W is subtracted so as not to fall below the predetermined lower limit.

  Subsequently, a weight addition process for adding the weight W of the first priority shown in step S509 is performed. In this process, the sum of the subtractions obtained by subtracting each weight W in the weight subtraction process is added to the weight W having the highest priority. Then, in the elapsed time clear process shown in step S511, the elapsed time T is cleared (T = 0), and the fourth weight setting process subroutine ends. Then, the icon display width adjustment process is performed, and each selection icon whose display width is adjusted according to the weight W added or subtracted as described above is displayed on the task bar 30. In this way, the display width of the selection icon corresponding to the application set with the highest priority is gradually increased by adding / subtracting the weight W each time the elapsed time T passes the predetermined time Tth. The display width of the selection icon corresponding to another application is gradually adjusted to be small.

  The screen transition before and after the addition / subtraction of the weight W will be described with reference to FIG. FIG. 17 is an explanatory diagram for enlarging and explaining the screen transition at the time of addition / subtraction of the weight W, FIG. 17 (A) shows an enlarged display state before addition / subtraction of the weight W, and FIG. The display state after addition / subtraction of W is shown enlarged.

  As shown in FIG. 17A, selection icons 31a, 31b, 31c, and 31d are displayed on the task bar 30 at a display width ratio of 0.38: 0.27: 0.1: 0.25. If the elapsed time T exceeds the predetermined time Tth (Yes in S107), the weights W of APL2 to APL4 are subtracted by the change amount ΔW, respectively, and the weight W of APL1 is added by ΔW × 3. Then, by performing the icon display width adjustment process, as shown in FIG. 17B, the display width of the selection icon 31a is set to be larger on the task bar 30 than before the predetermined time Tth has elapsed, and the selection icon The display widths 31b, 31c, and 31d are displayed smaller than before the predetermined time Tth has elapsed.

  In addition, in the determination process shown in step S501 described above, when there is an application whose priority is not set, for example, immediately after the start of APL4 and when the priority of APL4 is not set (Yes in S501), The priority change process shown in step S503 is performed. In this process, the priority of the application whose priority is not set is set to be the highest, and the other applications are set to be lowered by one. Then, the weight resetting process shown in step S505 is performed. Similarly to the weight resetting process shown in step S307, each weight W is reset according to the priority order, and then the processes in and after step S507 are performed. The The control unit 12 that executes the priority order changing process shown in step S503 may correspond to an example of “priority order setting unit” recited in the claims.

  The change of the weight W before and after the addition and subtraction of the weight W and its screen transition will be described with reference to FIGS. FIG. 18 is an explanatory diagram showing changes in the priority order and the weight W before and after the addition and subtraction of the weight W when there is an unset APL. FIG. 19 is an explanatory diagram illustrating an enlarged screen transition when adding / subtracting weight W, FIG. 19 (A) shows an enlarged display state before addition / subtraction of weight W, and FIG. 19 (B) shows weights. The display state after addition / subtraction of W is shown enlarged.

  When the priorities and weights W of APL1 to APL4 are set so as to be exemplified before addition / subtraction of weights W (T <Tth) in FIG. 18, as shown in FIG. The selection icons 31a, 31b, 31c, and 31d are displayed at a display width ratio of 0.38: 0.27: 0.1: 0.25. When the elapsed time T has passed the predetermined time Tth in this display state (Yes in S107), the priority order of APL4 is set to the first as shown in FIG. 18 after addition / subtraction of the weight W (T ≧ Tth). , APL1 to APL3 are changed so that the respective priorities are lowered by one. Then, the weights W of APL1 to APL3 reset according to the priority order are subtracted by 0.01, respectively, and the weight W of the highest priority APL4 is added to 0.38 by adding 0.03 to 0. .41 is reset.

  Then, the icon display width adjustment process is performed, and as shown in FIG. 19B, selection icons 31a, 31b, 31c, and 31d are displayed on the task bar 30 at 0.26: 0.24: 0.09: Displayed at a display width ratio of 0.41.

  As described above, in the mobile terminal 10 according to the present embodiment, one or more applications in which the processing screens (23a to 23d) are displayed in the main display area 21 by the icon display process performed by the control unit 12. The selection icons (31a to 31d) corresponding to the programs are displayed so as to occupy the entire task bar 30, and the selection icons corresponding to the completed application programs are excluded from the task bar 30. Then, the priority order of the application programs whose processing screens are displayed in the main display area 21 is set according to usage conditions such as a touch operation (S305, S309) or after a predetermined time (S503), and is displayed on the task bar 30. The display width of the selection icon is adjusted by the icon display width adjustment process based on the set priority and weight W.

As a result, the display width of the selection icon having a high priority, that is, the selection icon having a high possibility of being selected, is largely adjusted as compared with other selection icons having a low priority. It is possible to easily display a selection icon that is highly likely to be selected. In particular, since the display width of other low-priority selection icons is relatively small, the size of the main display area 21 and the task bar 30 in the display screen 20 does not change.
Therefore, the selection icon for selecting the application program on which the processing screen is displayed can be easily displayed without narrowing the main display area 21 for displaying the processing screen of the application program.

  Further, when any of the selection icons displayed on the task bar 30 is selected when a plurality of processing screens are displayed in the main display area 21, the priority order changing process shown in step S305 or S309 described above is performed. The priority of the application program corresponding to the selected selection icon is set highest, and the priority of the application program corresponding to the other selection icon is set low.

  As a result, the selection icon for the selected application program is considered to be an icon that is highly likely to be selected in the future, and the priority of the selected application program is set to be the highest so that the main display area 21 It is possible to reliably and easily display a selection icon that is highly likely to be selected without narrowing.

  Further, immediately after the application program is started, the priority order is not set, and when any one of the selection icons displayed on the task bar 30 is selected, the application program in which the priority order is not set (unset program) Is set to be higher than the application program corresponding to the selected selection icon.

  Immediately after startup, the priority order of the application program cannot be accurately grasped, and therefore setting the wrong priority order can be suppressed by not setting the priority order. After that, when one of the other application programs is selected and its priority is set to the highest, the unset program among the remaining application programs becomes the application program with the shortest time since startup. Thus, by setting the priority of the unset program so as to be the next higher than that of the selected application program, it is possible to realize the setting of the priority according to the use situation.

  If there is an application program for which the priority order is not set after the lapse of a predetermined time (T ≧ Tth), the priority order of the unset program is set to the highest in the priority order change process shown in step S503. When setting the priority of an unset program that was not set immediately after startup after a predetermined time has elapsed, the unset program becomes the application program with the shortest time since startup. Therefore, by setting the priority of the unset program to the highest level, the priority of the unset program can be set according to the usage status.

  In particular, when a plurality of selection icons are displayed on the task bar 30, the display width of the selection icons corresponding to other application programs other than the application program with the highest priority is adjusted to gradually decrease over time. In accordance with the display width thus reduced, the display width of the selection icon corresponding to the application program with the highest priority is gradually adjusted.

  As a result, the display width of the selection icon having a high priority, that is, the selection icon having a high possibility of being selected is gradually adjusted with time, so that the selection icon having a high possibility of being selected is selected. It is possible to display more easily.

  Further, since the display device 13 includes a touch panel provided with an input unit for selecting an icon on the outer surface, the display device 13 is displayed on the task bar 30 even when the icon is selected by touching the display screen 20 like a touch panel. The selection icon can be easily selected.

  Note that a change amount setting unit capable of setting the change amount for gradually reducing the display width of the selection icon over time, that is, the change amount ΔW described above to a desired value may be employed. As the change amount setting means, for example, a touch operation on the display screen 20 or an input operation on the operation button 14a is assumed. As a result, for example, in a work environment where many application programs are used one after another in a short time, the change amount ΔW is set according to the assumed selection icon selection state, such as reducing the change amount ΔW. The icon display suitable for the working environment can be realized.

[Second Embodiment]
Next, a mobile terminal according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 20 is a flowchart illustrating the flow of icon display processing in the control unit 12 according to the second embodiment. FIG. 21 is a flowchart illustrating the subroutine flow of the fourth weight setting process of FIG. FIG. 22 is a flowchart illustrating the flow of the enlarged display processing subroutine of FIG.

  The mobile terminal 10 according to the second embodiment replaces the icon display process with the flowchart shown in FIG. 3 in order to facilitate selection of the selection icon even when the display width of the selection icon is gradually reduced with time. The point that is implemented based on the flowchart shown in FIG. 20 is different from the portable terminal according to the first embodiment. Therefore, substantially the same components as those of the mobile terminal according to the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  In the icon display process in the first embodiment, a selection icon with a low selection frequency has a display width that gradually decreases with time, so that it may be difficult to select the icon.

  Therefore, in the icon display processing in the present embodiment, one or more icons (hereinafter referred to as low frequency icons) whose weight W is equal to or smaller than a predetermined threshold value Wth and whose display width is reduced are removed and removed in this way. An enlarged display icon 32 indicating the presence of a low-frequency icon is displayed on a part of the task bar 30. When this low frequency icon is desired to be selected, the low frequency icon is displayed instead of the icon already displayed on the task bar 30 in response to the selection of the enlarged display icon 32. In the present embodiment, the display width of the enlarged display icon 32 is set to be larger than the display width corresponding to the predetermined threshold value Wth. The predetermined threshold value Wth is set to 0.2, for example.

Hereinafter, the icon display processing in the present embodiment will be described with reference to the flowchart shown in FIG.
As in the first embodiment, during the repetitive processing from step S101 in FIG. 20, if the elapsed time T from the start of time measurement in the time measurement processing has passed the predetermined time Tth (Yes in S107), step A fourth weight setting process shown in S500a is performed. In the fourth weight setting processing subroutine, as in the first embodiment, after the processing up to step S511 in FIG. 21 is performed, each of the selection icons displayed on the taskbar 30 in step S513 is displayed. Is set to k = 1.

  Next, in the determination process shown in step S515, it is determined whether or not the kth weight Wk is equal to or less than a predetermined threshold value Wth. Here, when three selection icons 31a, 31b, and 31c are displayed on the task bar 30 and the weight W corresponding to the first selection icon 31a exceeds a predetermined threshold value Wth (No in S515), Since N = 3, it is determined No in step S519, incremented as k = k + 1 in step S521, and the determination process in step S515 is performed again. If the weight W corresponding to the selection icons 31b and 31c also exceeds the predetermined threshold value Wth (No in S515), k = N (Yes in S519), and in step S523, the APL with the weight W = 0. If there is no APL with a weight W = 0, it is determined No and the fourth weight setting process ends. Note that the control unit 12 that performs the determination process shown in step S515 may correspond to an example of a “determination unit” described in the claims.

  On the other hand, if any of the weights W is equal to or less than the predetermined threshold value Wth (Yes in S515), it is determined that the selection icon is a low-frequency icon, and the weight W = 0 is set in step S517. Note that the process shown in step S517 can be regarded as a process of removing the low-frequency icon from the task bar 30 by setting the weight W to 0, and the control unit 12 that performs this process is described in the claims. It can correspond to an example of “removing means”.

If there is an APL set with the weight W = 0 as described above (Yes in S523), the weight resetting process shown in step S525 is performed. In this process, the weight W of the selection icon excluding the low-frequency icon (weight W = 0) is recalculated using the following equation (5). In Equation (5), ΣWb represents the sum of the weights W of the selection icons excluding the low-frequency icon.
W1 = 1 / ΣWb × W2 (5)
As described above, when the weight W is recalculated, the fourth weight setting process ends.

  When the weight W is set to 0 as described above and the fourth weight setting process is completed, the determination process shown in step S108 of FIG. 20 determines Yes and the enlarged display for step S108a. Icon display processing is performed. In this process, an enlarged display icon 32 is displayed at one end of the task bar 30. If the enlarged display icon 32 is not selected by a touch operation or the like (No in S108b), the icon display width adjustment process shown in step S111 is performed. In this process, each selection icon is adjusted to a display width corresponding to the corresponding weight W and displayed in an area excluding the enlarged display icon 32 in the task bar 30. The control unit 12 that executes the enlarged display icon display process may correspond to an example of an “enlarged display icon display unit” recited in the claims.

  The change in the weight W before and after the display of the enlarged display icon 32 and the screen transition will be described with reference to FIGS. FIG. 23 is an explanatory diagram showing a change in the weight W before and after displaying the enlarged display icon 32. FIG. 24 is an explanatory diagram for explaining the screen transition when the enlarged display icon 32 is displayed. FIG. 24A shows a display state before the enlarged display icon is displayed, and FIG. The display state after the icon is displayed.

  When the priorities and weights W of APL1 to APL3 are set as before the display of the enlarged display icon in FIG. 23, the main display area 21 has APL3 as shown in FIG. The processing screen 23c is displayed in the top window, and the icons 31a, 31b, 31c for selection are displayed on the task bar 30 at a display width ratio of 0.21: 0.21: 0.58. Then, when the elapsed time T has passed the predetermined time Tth (Yes in S107), the weight W corresponding to the icon 31a and the weight W corresponding to the icon 31b are subtracted from 0.21 and become equal to or less than the predetermined threshold Wth. (Yes in S515), these weights W are set to 0 as after the display of the enlarged display icon in FIG. Then, the weight W of the selection icon 31c of APL3 is recalculated as 1 by the above equation (5).

  For this reason, as shown in FIG. 24B, an enlarged display icon 32 is displayed on the task bar 30 (S108a), and a selection icon 31c whose weight W is recalculated to 1 is displayed. .

  As described above, when a touch operation or the like for selecting the enlargement display icon 32 is performed in a state where the enlargement display icon 32 is displayed on the task bar 30 (Yes in S108b), the enlargement shown in step S600 is performed. Display processing is performed. In this enlarged display processing subroutine, first, the icon width enlarged display processing shown in step S601 of FIG. 22 is performed. In this process, the selection icon and the enlarged display icon 32 displayed on the task bar 30 are removed from the task bar 30, and one or more low-frequency icons (weight W = 0) are displayed on the task bar 30. Displayed so that the display width is uniform.

  A display state by the icon width enlargement display process will be described in detail with reference to FIG. FIG. 25 is an explanatory diagram for explaining the screen transition when the enlarged display icon 32 is selected. FIG. 25A shows the display state before the enlarged display icon 32 is selected, and FIG. The display state after selection of the display icon is shown.

  As illustrated in FIG. 25A, selection icons 31c and 31d and an enlarged display icon 32 are displayed on the task bar 30, and the weights W of the selection icons 31a and 31b are set to 0, respectively. When the enlarged display icon 32 is touched in the display state (Yes in S108b), the icon width enlarged display process is performed. As a result, as illustrated in FIG. 25B, the selection icons 31c and 31d and the enlarged display icon 32 are removed from the task bar 30, and the selection icons 31a and 31b whose weight W is set to 0 are displayed. The task bar 30 is enlarged and displayed so that the display widths are equal.

Step S603 is performed until the enlarged selection icon is selected on the display screen 20 by a touch operation or an area different from the task bar 30 (the enlarged selection icon) is selected by the touch operation. , S605 repeats the determination of No. For example, when the enlarged selection icon 31a is selected by a touch operation (Yes in S603), the weight calculation process shown in step S607 is performed. In this process, the weight W of the selection icon selected in the enlarged display state is calculated using the following equation (6). In Equation (6), N3 represents the total number of applications in which the weight W is set to a value different from zero.
W = 1 / (N3 + 1) (6)

Next, the weight recalculation process shown in step S609 is performed. In this process, the weight W corresponding to other applications excluding the application of the selection icon selected in the enlarged display state is recalculated using the following equation (7).
W1 = N3 / (N3 + 1) × W2 (7)

  Subsequently, the priority order changing process shown in step S611 is performed. In this process, the priority of the application corresponding to the selection icon selected in the enlarged display state is set to be the highest, and the priority of other applications having a higher priority than this application is lowered by one. Is set as follows. Next, the weight resetting process shown in step S613 is performed, and each weight W is reset according to the priority, similarly to the weight resetting process shown in step S307. Then, the icon width enlarged display release process shown in step S615 is performed, the enlarged display of the selection icon by the enlarged display process is released, and the main enlarged display process subroutine ends.

  Changes in priority and weight W before and after selection of the enlarged selection icon and its screen transition will be described with reference to FIGS. 26 and 27. FIG. FIG. 26 is an explanatory diagram showing changes in priority and weight W before and after selection of an enlarged selection icon. FIG. 27 is an explanatory diagram for explaining screen transition when an enlarged selection icon is selected. FIG. 27A shows a display state before selection of the enlarged selection icon, and FIG. B) shows a display state after selection of the enlarged selection icon.

  When the priorities and weights W of APL1 to APL4 are set as before the selection of the enlarged selection icon in FIG. 26 and the enlarged display icon 32 is selected by a touch operation (in S108b) Yes), as shown in FIG. 27A, the selection icons 31a and 31b whose weight W is set to 0 are enlarged and displayed on the task bar 30 so that their display widths are equal. When the enlarged selection icon 31a is selected by a touch operation or the like (Yes in S603), the weight W corresponding to the selection icon 31a is calculated as 0.33 using the above equation (6). The weights W corresponding to the selection icons 31c and 31d are calculated as 0.4 and 0.27 using the above equation (7). After that, the priority of APL1 selected in the enlarged display state is set to the highest as after selection of the enlarged selection icon in FIG. 26, and the priorities of APL3 and APL3 are set to the second and third ranks. In accordance with the change in the priority order, the weights W of the selection icons 31a, 31c, and 31d are reset to 0.4, 0.33, and 0.27.

  For this reason, as shown in FIG. 27B, the enlarged display icon 32 is displayed on the task bar 30 (S108a), and the selection icons 31c, 31d, and 31a are 0.33: 0.27. : Displayed at a display width ratio of 0.4.

  If an area different from the task bar 30 (enlarged selection icon) is selected by a touch operation on the display screen 20 (Yes in S605), the icon width is not particularly calculated without recalculating the weight W. The enlarged display canceling process is performed, the above-described enlarged display is canceled, and the subroutine of the enlarged display process ends.

  As described above, in the mobile terminal 10 according to the present embodiment, when the selection icon (low frequency icon) for which the weight W is determined to be equal to or less than the predetermined threshold value Wth is removed from the task bar 30, it is removed in this way. An enlarged display icon 32 indicating the presence of the low-frequency icon is displayed on the task bar 30 along with other selection icons in one direction so as to be selectable. When the enlarged display icon 32 is selected, the selection icon displayed on the task bar 30 is removed, and the low frequency icon is displayed on the task bar 30 so as to be selectable.

  As described above, in the case where the enlarged display icon 32 is displayed on a part of the task bar 30 instead of the low frequency icon whose weight W is equal to or smaller than the predetermined threshold Wth and the display width is small, and this low frequency icon is desired to be selected. In response to the selection of the enlarged display icon 32, the low frequency icon is displayed instead of the selection icon already displayed on the task bar 30. Thereby, even a selection icon (low frequency icon) with low selection frequency can be easily displayed.

  Further, since the display width value of the enlarged display icon 32 is set to be larger than the display width corresponding to the predetermined threshold value Wth, the enlarged display icon 32 can be easily displayed on the task bar 30.
