Description

  The present invention relates to a portable information terminal in which a display device and an operation detection unit cooperate to provide an operation unit that replaces a button, a key switch, or the like.

  There are many devices such as a touch panel that have a means (operation detection unit) for inputting a position and are operated by a user touching the operation detection unit with his / her finger or the like. For example, a mobile phone, a POS terminal, a ticket vending machine, ATM or the like. In these devices, the display device and the operation detection unit cooperate to provide functions as buttons and key switches. A user touches a position of a button or key switch displayed as a display item on the display device with a finger or a pen and operates the device.

In this operation, a finger is placed between the display item displayed on the display device and the eyes of the user who operates the device. Accordingly, display items such as buttons are covered with a finger and are hidden or difficult to see from the user's eyes.
If the area of the display item is still larger than the finger, some of the display item is visible to the user, so let the user recognize that the operation has been accepted by changing the color of the display item or blinking it. I was able to.
In addition, there is one that can cope by preparing a dedicated thin touch pen so that display items are not hidden.

However, in a device that has only a small screen even though it is a normal device that is operated with a finger, such as a mobile phone, display items are often small. In particular, in a scene where an operation is performed in a state where a large number of buttons are displayed side by side, such as character input, the area of each button may be smaller than a finger, and many buttons may be arranged without gaps. In such a case, there are cases where the user who performs the operation cannot visually confirm which button has been pressed and whether the target button has been reliably pressed. In the case of a dedicated button, it is possible to make the user recognize which button is touched by providing a unique feel by providing irregularities on the top and the periphery. However, in the aspect in which the type and position of the display component are changed according to the situation, even if the operation detection unit is provided with irregularities at the specific position, whether or not there is a display component at that position. It is not easy for the user to correctly recognize which display component.
In order to avoid this inconvenience, it is known that a button that indicates which button is pressed is displayed as a balloon at the further tip (upward) of the finger pressing the operation button (see, for example, Non-Patent Document 1).

As a technique related to this, a technique for enlarging and displaying a display image of a designated portion in order to prevent erroneous input is known (see, for example, Patent Document 1). More specifically, the display means, a position designation means provided on the front surface of the display means for reading the position touched by the user, and a position detection means for detecting coordinates for the display means based on a signal from the position designation means; A pressure detecting means for detecting the pressure of the position specifying means; and an enlarged display means for enlarging a display area of a certain range including the position based on the detected position, wherein the pressure detecting means has a predetermined predetermined value. When a pressure equal to or greater than a value is detected, control is performed so that an area within a certain range including the position touched by the user is enlarged, and the position designation unit reads the position of the enlarged display area. It is a thing.
In addition, a technology is known that enables a user to recognize an image displayed at a touch-operated location hidden by a touch-operated finger on a portable information terminal having a touch panel by sliding the display content. (For example, refer to Patent Document 2).

Japanese Patent Laid-Open No. 10-154042 JP 2009-301282 A

“[Practice Q & A] iPhone thorough use of“ 30 tips ”character input edition / home screen / trouble edition”, [online], August 22, 2008, Nikkei Trendy Net feature article, [December 1, 2010 search ], Internet <URL: http: //trendy.nikkeibp.co.jp/article/special/20080822/1017851/>, full keyboard image reference

  If it is assumed that operation is always performed with a touch pen, the area hidden by the thin pen tip is small. However, it is troublesome to use tools to operate the equipment. There is a situation in which a device that can be directly operated by a user's finger and provides simple operability is accepted in the market. However, with regard to touch operations with fingers, on mobile phones, smartphones, PDAs, handy terminals, and other devices with small screens, the contents of the display, especially the contents of the buttons, are hidden by the finger, and the user himself does not know what is pressed. There is a problem. This will increase the rate of misoperation.

  The present invention has been made in consideration of the above-described circumstances, and in a normal portable device, a user can determine which display component in the screen is accepted to operate by touching the screen with fingers. Provides a technique that can be easily viewed.

  The present invention includes a display unit that has a screen and displays an operation display component on the screen, a touch operation that touches the screen and an operation detection unit that detects a position of the touch operation, the display unit, and the operation detection unit A control unit for controlling the display component, and the control unit changes the display mode of the display component in response to the detection of the touch operation by the operation detection unit at the display position of the display component and the display component. Provided is a portable information terminal characterized in that the display unit is controlled so that display of all or part of the screen including the display is shifted in one direction.

  Further, from a different point of view, the present invention allows the computer to display an operation display component on the screen of the display unit, to detect a touch operation that touches the screen using the operation detection unit and a position of the touch operation, and to display the display. In response to detection of a touch operation at the display position of the component, the display mode of the display component is changed, and control is performed so that the display of all or part of the screen including the display component is shifted in one direction. A display control method for a portable information terminal is provided.

In the portable information terminal of the present invention, the control unit changes the display mode of the display component in response to the detection of the touch operation by the operation detection unit at the display position of the display component, and includes all the display components. Alternatively, since the display unit is controlled so as to shift the display of a part of the screen in one direction, the portable information terminal has only a small screen although it is a normal device to operate with a finger. In addition, the user can easily visually recognize which display component is accepted as an operation.
That is, when the user operates the screen with a finger, the display mode of the operated display component changes and the display of all or a part of the screen including the display component shifts. Even if the display component is hidden by a finger and cannot be seen, it is possible to know which display component is pressed.
The display control method according to the present invention produces the same effects.

  In the present invention, the operation display component is a display element that informs the user that the operation is accepted when the position where it is displayed on the screen is operated. Representative examples include operation buttons, list boxes, check boxes, radio buttons, hyperlinks, and the like. However, the present invention is not limited to this and is used as an operation means of a graphical user interface. However, the present invention is not limited to a graphical user interface. Even a simple rectangle or the like is included in the operation display component as long as it is a display element that allows the user to recognize that an operation for the rectangle is accepted. In the embodiment described later, the display component corresponds to an alphabet operation button “END” button.

  The display unit displays the operation display component on a screen and displays information to be provided to the user. A circuit for controlling the display is also included. A specific mode is, for example, a liquid crystal display panel. However, the method and the structure are not limited as long as they are applicable as a display element of a portable information terminal. In an embodiment described later, the display unit corresponds to a display panel and a display control unit.

The operation detection unit detects that an operation touching the screen is performed and detects a position on the screen where the operation is performed. The specific aspect is a touch panel, for example. A drive circuit is also included. The principle of detecting contact with the screen is not limited. It may be a pressure-sensitive type, an electrostatic type, an optical type, or any other type. As the position detection resolution, a resolution capable of detecting a change in position corresponding to the size of a finger can be applied. In an embodiment described later, the operation detection unit corresponds to a touch panel input unit. Preferably, the position of the touch operation is detected as coordinates in the horizontal direction (X direction) and the vertical direction (Y direction) of the screen.
The touch operation is an operation of touching the screen. However, in the present invention, an operation of directly touching the screen with a user's finger is considered. However, what touches the screen is not necessarily limited to fingers, and may be a pen or the like. It should be noted that an operation of releasing a finger or the like that has been touching the screen is a release of the touch operation. The operation detection unit detects that a finger has touched the screen, that the finger has continued to touch the screen, that the position of the finger has moved (cancel touch operation), and that the finger has left the screen.

The control unit controls the display unit and the operation detection unit. A specific mode is a CPU or a microcomputer. In an embodiment described later, the control unit corresponds to a CPU included in the portable information terminal.
The control unit changes the display mode of the display component displayed at the position where the touch operation is performed. As a specific example of the changed display mode, it can be considered that the color of the display component is reversed or blinked. Not limited to this, it includes a visual change so that the user can visually recognize that the display component is different from the state before the operation. It also includes thickening the border of the display component, changing the color but not reversing, changing part or all of the shape while maintaining the size substantially. In the embodiment to be described later, the color of the operation button is reversed.

Shifting the display of a part of the screen including the display component in one direction indicates the following. In general, a screen that accepts a touch operation is arranged by dividing display components that are targets of the touch operation into regions or hierarchizing. This is because the screen is designed so that the user who sees the screen can easily understand the place and meaning of the touch operation. When the display on the screen is divided into several layers or hierarchized in this way, the division or hierarchy including the display component to be touched is shifted and displayed in one direction.
For example, the display screen of FIG. 3 to be described later is divided into three areas from top to bottom. From top to bottom, a status display area that shows the operating status of the device, a message display area that displays the content of the message to be created, and a character input area that displays alphabet keys (operation buttons) for inputting characters of the message is there. In this case, a specific example is that the character input area is shifted in response to a touch operation of any one of the operation buttons.
Further, the display screen of FIG. 5 to be described later is hierarchically displayed so that when a “cancel” button is touched, a dialog box for confirmation is displayed in response thereto. In this case, an example will be described in which the display of the dialog box is shifted in response to the touch of the operation button “Yes” or “No” on the dialog box.

Hereinafter, preferred embodiments of the present invention will be described.
When the touch operation is detected at the display position after the touch operation is detected at the display position of the display component, the control unit determines that the operation on the display component is confirmed and responds to the operation of the display component. May be performed. In this way, the user can perform a reliable operation by canceling the touch operation after confirming which display component the touch operation has been accepted as.

  In addition, the control unit changes the display mode of the display component in response to detection of the touch operation at the display position of the display component, and displays the screen when the touch operation continues for a predetermined time. A shift display may be used. In this way, it is possible to notify the user that the touch operation has been detected by quickly changing the display mode using the detection of the touch operation as a trigger, and display by moving to the next operation within a predetermined time. It is possible to move to the next operation quickly without shifting.

  Furthermore, when the touch operation is detected at the display position of the display component and the position of the touch operation deviates from the display component, the control unit determines that the operation on the display component has not been performed and changes the touch operation position. The display mode may be restored to the original state, and the processing corresponding to the operation of the display component may not be performed. In this way, when the touch operation is not detected as the operation of the display component intended by the user or when the user wants to perform the operation again, the operation is easily canceled by removing the position of the touch operation. be able to.

The display unit displays first and second display parts for operation,
When the touch operation is moved to the display position of the second display component after the touch operation is detected at the display position of the first display component, the control unit restores the display mode of the first display component. The display mode of the second display component is changed, and when the touch operation is released at the display position of the second display component, processing corresponding to the operation of the second display component is performed. The processing according to the operation may not be performed. In this way, the user cancels the operation on the first display component by the simple operation of moving the position from the first display component to the second display component without releasing the touch operation, and the second display component. Can be operated.

  Further, the control unit may perform control so as to restore the display of the screen that has been shifted and displayed when the touch operation is released. In this way, while the touch operation is continued, even if the position of the touch operation is moved, the screen display is maintained in a shifted state, so that the display is stabilized.

  Furthermore, the control unit determines a direction to shift the display of the screen according to the position where the touch operation is detected, and the direction is a direction from the position where the touch operation is detected toward the center of the screen. May be. In this way, since there is a margin of distance corresponding to at least half of the screen from the position where the touch operation is performed to the edge of the screen in the shift direction, the display component where the touch operation is performed protrudes from the screen due to the display shift. There is no end.

  Alternatively, the control unit determines a direction in which the display of the screen is shifted and displayed according to a position where the touch operation is detected, and the direction is a position where the touch operation is detected in each of the upper, lower, left and right edges of the screen. The shortest distance from each edge to each edge may be shifted toward the largest edge. In this way, the screen display is shifted toward the farthest edge from the position where the touch operation is performed, so that the display component where the touch operation is performed does not protrude from the screen due to the display shift.

  The control unit may provide a setting menu so that the user can change the amount of display to be shifted. In this way, it is possible to set the shift amount according to the size of the fingers and the user's preference.

The control unit may not shift the screen display when a touch operation is performed at a position other than the display position of the display component. In this way, since the screen does not shift even if a position other than the operation display component is touched, the user can easily recognize whether or not the operation has been accepted.
The various preferable aspects shown here can also be combined.
Hereinafter, the present invention will be described in more detail with reference to the drawings. In addition, the following description is an illustration in all the points, Comprising: It should not be interpreted as limiting this invention.

≪Configuration of portable information terminal≫
FIG. 1 is an explanatory view showing an example of the appearance of the portable information terminal of the present invention. The portable information terminal 11 in FIG. 1 is a so-called smartphone. The portable information terminal 11 includes a display panel 13 having a touch panel, a power button 15, an operation button 17, an earpiece 19, and a call mouth 21. The power button 15 and the operation button 17 are mechanical operation buttons, but other operation buttons are displayed on the display panel 13 as display components. When the user touches the position where the operation button is displayed with a finger, the CPU (not shown) reads the operation and the position on the touch panel, and performs processing assuming that the operation button displayed at the position is pressed.
FIG. 2 is a block diagram showing the main electrical configuration of the portable information terminal 11 shown in FIG. As shown in FIG. 2, the portable information terminal 11 includes a touch panel input unit 23, a key input unit 25, a display control unit 27, a display panel 13, a CPU 31, a ROM 33, a RAM 35, and a call / communication unit 37.

  The touch panel input unit 23 includes a touch panel sensor disposed on the surface of the display panel 13 and a detection circuit related thereto. A pressure-sensitive type or electrostatic type can be applied as the touch panel. The touch panel input unit 23 corresponds to the operation detection unit of the present invention. The key input unit 25 includes the power button 15 and the operation button 17 and their detection circuits. The display control unit 27 includes a circuit for processing display contents, that is, display data, a video memory for storing the display data, and a circuit for controlling drawing of the display panel 13 based on the display data stored in the video memory. Have. The display panel 13 is a liquid crystal display device and its drive circuit. However, a display device other than the liquid crystal display device, for example, an organic EL display may be used.

  The CPU 31 controls operations of the touch panel input unit 23, the key input unit 25, the display control unit 27, and a call / communication unit 37 described later, and processes data including display data. The ROM 33 stores a processing program to be executed by the CPU 31. Data of display parts such as operation buttons is stored. Furthermore, the setting value by the setting menu mentioned later is stored. A flash memory is applied as the ROM 33. However, other nonvolatile storage elements such as EEPROM and hard disk devices are also applicable. The RAM 35 provides a work area for the CPU. Further, a processing program stored in the ROM 33 may be downloaded and stored when the CPU executes processing. This method is used when the RAM reading speed is faster than the ROM reading speed. Further, a storage area as the video memory may be allocated in the RAM 35. SRAM is applied as the RAM.

  When the portable information terminal 11 is turned on, the CPU 31 executes a boot program stored on the ROM 33. Alternatively, the boot program on the ROM 33 is once transferred to the RAM 35, and the CPU 31 executes the boot program downloaded to the RAM 35. When the CPU 31 executes the boot program, display data is created on the RAM 35. The created display data is processed by the display control unit 27 and stored in the video memory. The data stored in the video memory corresponds to the content displayed on the display panel 13 from time to time. The display data includes standard display parts such as windows, operation buttons, list boxes, and text boxes, and display parts such as bitmap image data and characters.

  When the user touches the display panel 13, the touch panel input unit 23 detects an input. It also provides information that identifies the location of the input. The touch panel input unit 23 notifies the CPU 31 that an input has been detected. Alternatively, the CPU 31 monitors input by polling processing or the like. In response to the input detection, the CPU 31 acquires the input position (input coordinates) detected by the touch panel input unit 23. Then, it is determined which display component displayed on the display panel 13 corresponds to the display position of the input coordinates. Based on the determination result, the CPU 31 performs processing according to the operation. Such processing is prepared in advance as a processing program for each window or component. For example, when it is determined that an operation button displayed at a certain position on a certain screen has been pressed, the CPU 31 executes the contents of the processing program corresponding to the pressing of the operation button.

≪Processing for character input operation≫
Subsequently, an operation input process according to the present invention will be described. As a representative example of operation input, character input using a soft keyboard is taken up.
FIG. 3 is an explanatory diagram showing a character input operation to the portable information terminal of the present invention. FIG. 3A shows a message input screen for creating a new message and sending it as an e-mail. The screen of FIG. 3A is roughly divided into three areas from top to bottom. The top part is a status display area 41. In the status display area 41, an icon indicating the radio wave reception intensity, an icon indicating the remaining battery level, and the current date and time are displayed.

  Below the status display area 41 is a message display area 43. The message display area 43 displays the contents of the created message. More specifically, a title of “new message” and a “cancel” button 42 are displayed at the top of the message display area 43. When the “Cancel” button 42 is pressed, the message creation is stopped, and the screen moves to a standby screen (not shown). Under the title, “Destination: xxxxxxxx” is displayed that the created message is sent to xxxxxxxx. Below the destination is a message display field. Nothing is currently entered, and a black rectangle indicating the cursor position is displayed.

Below the message display area 43 is a character input area 45. The character input area consists of input keys 47. The input keys 47 are arranged with so-called “QWER” alphabet keys (operation buttons). However, this is an example. For example, each time the “Shift” button at the lower left corner is pressed, uppercase letters and lowercase letters are switched. In addition, an “Akasana” button that accepts Japanese kana input by a predetermined operation may be displayed.
When any operation button of the input key 47 is pressed, the CPU 31 inputs a character at the cursor position in the message display area 43.

  An operation of inputting the character S as the first character of the message on the screen of FIG. In order to input the letter S, the “S” button of the alphabet keys is pressed. However, when the user moves the finger 51 over the “S” button to press the “S” button, the entire “S” button is hidden by the fingertip. FIG. 3B shows a state where the “S” button is hidden by the finger 51. Since the “S” button is smaller than the finger 51, it is a blind spot of the fingertip. Therefore, even if the CPU 31 performs highlighting that changes the color of the “S” button or blinks in response to the “S” button being pressed, the user can confirm that the user has operated the “S” button. Cannot be seen.

  According to the present invention, the CPU 31 performs control so that the “S” button is highlighted and all or a part of the screen is shifted and displayed. FIG. 4 is an explanatory diagram showing how the screen display changes in response to a character input operation of the portable information terminal of the present invention. The finger 51 is in the same position as in FIG. In FIG. 4A, the “S” button operated by the user is emphasized, and the display on the screen is entirely shifted upward. The arrow icon 52 is an icon that informs the user that the display is in a shifted state. When the display on the screen is shifted as a whole, an area not displayed until then appears. As shown in FIG. 4A, the area not displayed so far may be a solid black color, and the arrow icon 52 may be displayed in that area. In addition, the contents to be displayed only in a state where the display is shifted may be displayed in the area. For example, an operation guidance regarding an input correction method. Since the CPU 31 shifts the screen as a whole, the processing of the CPU 31 is simpler and the processing load is lighter than when only a part of the screen, for example, the “S” button is shifted. The screen may be shifted only when the “S” button is continuously pressed for a predetermined time (first period), for example, 0.5 seconds. The CPU 31 may return the display to the state before the shift after shifting the display for a predetermined period (second period), for example, for 1 second. During the second period, the input of the next operation button may not be accepted. Alternatively, the shift may be returned to the original in response to the finger 51 being separated from the touch panel. The highlighting of the “S” button should also be stopped when the shift is restored.

  By doing so, there is no problem that the screen is shifted only by touching the button with a little finger. In addition, a user who wants to input characters quickly may press the operation buttons one after another at intervals shorter than the first period. In that case, the CPU 31 does not shift the display and does not prohibit the input of the operation buttons. The press of those operation buttons is accepted. On the other hand, when the user wants to make a reliable input while confirming the operated button, the user may press the operation button beyond the first period. By doing so, it is possible to perform input while confirming the pressed operation buttons one by one.

  In the above example, the screen display is shifted upward, but the following idea can be applied when determining the shift direction. That is, the direction with the longest distance from the operation position to the edges in the vertical and horizontal directions of the display panel 13 is set as the shift direction. This is because the button operated when shifting the display does not protrude from the screen. However, there is also a way to avoid shifting the display downward in consideration of the finger 51 extending from below. However, as another concept, there is also a concept of shifting in a certain direction regardless of the input position. This is an approach that emphasizes a unified response to operations. There is also a concept of shifting toward the center point of the screen. This is because if the display is shifted in the direction toward the center point, it is considered that the operated button does not protrude from the screen because there is a sufficient amount of shift.

  FIG. 4A shifts the entire screen, while FIG. 4B shifts only the character input area 45 in the right direction. The status display area 41 and the message display area 43 are not shifted. In FIG. 4B, the character input area 45 is shifted to the right. This is because if the character input area 45 is shifted upward, the lower part of the message display area 43 is hidden and the input character cannot be confirmed. In addition, it is considered that when the character input area 45 is shifted to the left, it protrudes from the left edge of the screen. In this way, when shifting the display of a part of the screen, in determining the shift direction, in addition to the concept of the shift direction described above, the display contents of other areas hidden by the shift display are related to the operation. It is preferable to further consider whether or not the content is to be.

FIG. 5 is an explanatory diagram showing another aspect of shifting the display of a part of the screen. When the “cancel” button 42 is pressed on the new message creation screen of FIG. 3 or FIG. 4, the CPU 31 displays a dialog box 55 for user confirmation on the screen in response thereto. This series of displays can be regarded as a structure in which the display of the dialog box 55 based on the touch operation of the “cancel” button 42 is layered below the screen display of FIG. 3 or 4.
FIG. 5A shows a screen on which the CPU 31 displays the dialog box 55 in response to the touch operation of the “Cancel” button 42. FIG. 5B shows a state in which the CPU 31 shifts and displays the dialog box 55 in response to the touch operation of the “Yes” button on the screen of FIG. Although the shift direction of (b) is above the screen, the shift direction is not limited thereto. The shift direction may be determined based on the same concept as in FIG.

≪Setting menu≫
Furthermore, the user may be able to set the shift direction and shift amount in advance using the setting menu. Further, the state during the shift may be displayed as an animation. That is, the screen display may be shifted step by step.
The setting menu is realized by the CPU 31 executing a processing program.

FIG. 6 is an explanatory diagram showing an example of the setting menu according to the present invention. When the setting menu is executed, a setting menu screen shown in FIG. 6 is displayed on the display panel 13. In the change menu display area 49, as a setting item, a check box for displaying a display shift direction, a shift amount, and a shift is displayed. The shift direction can be selected from the screen center, the far side from the screen edge, the upper direction, the left direction, the right direction, and the lower direction. The shift amount is specified by the number of pixels. 0-100 can be input. If 0 is set, display shift is not performed.
When the “end” button 48 on the right side of the title of the setting menu is pressed, the CPU 31 writes the setting contents of each item in the ROM 33. Then, the setting menu is terminated. Thereafter, the display shift is performed based on the setting value on the setting menu screen described above.

≪Operation to correct incorrect input≫
Consider the case where the user tried to press the “S” button with the finger 51 in the above example, but accidentally pressed the “A” button on the left side. FIG. 7 is an explanatory diagram showing an operation for correcting an erroneous input in the portable information terminal of the present invention. When the first period elapses while the finger 51 is pressing the “A” button, the screen display is shifted, and the screen shown in FIG. 7A is displayed. Here, the user notices that the user has accidentally pressed the “A” button.

  In this case, the user may move the finger 51 from the current position to the right side where the target “S” button is located. According to the present invention, since the display is shifted, the target “S” button is not hidden by the finger 51 and the user can easily recognize the direction in which the finger should be moved. When the user moves the finger 51 in the direction of the “S” button, the touch panel input unit 23 detects the movement of the finger 51 and notifies the CPU 31 of it. The CPU 31 changes the operation target from the “A” button to the “S” operation button on the right side according to the amount of movement of the finger 51 to the right. Accordingly, the highlighting target is changed.

The user can adjust the movement amount and direction of the finger 51 while watching the change in highlighting. In this case, the finger may be moved to the right (see arrow R), and the finger 51 may be released from the touch panel in a state where the highlighting has changed from the “A” button to the “S” button. When the finger 51 moves away from the touch panel, the display returns to the state before the shift, and the “S” button is not highlighted.
By the above operation, the correction can be made such that the first selected “A” button is in a non-selected state and the “S” button is in a selected state instead. As described above, erroneous input can be corrected with a simple operation.

  As described above, character input has been described as a representative example. However, the present invention is not limited to operation buttons. For example, as a means for operating a graphical user interface such as a list box, a check box, a radio button, and a hyperlink. This also applies to display parts that are normally used. These operating means are those used in computer programs and web sites.

≪Flowchart≫
A process executed by the CPU 31 when inputting the character will be described. 8 and 9 are flowcharts showing processing executed by the CPU 31 of the portable information terminal 11 of the present invention. The flowcharts of FIGS. 8 and 9 are obtained by extracting processing particularly related to the features of the present invention. Hereinafter, the processing will be described with reference to the flowchart.

  After the power is turned on, the CPU 31 reads the setting value related to the setting menu of FIG. 6 as one of initialization processes and stores it in the RAM 35 as a temporary variable (step S11). Specific examples of the setting value are a variable (referred to as variable D) corresponding to the setting of “shift direction” and a variable S corresponding to “shift amount”. Further, it is a variable T indicating the display time of the animation. T is a predetermined time (for example, 0.5 seconds) when “display animation” is checked, and takes a value of zero (0) when the check is not checked.

  Thereafter, the CPU 31 monitors whether or not the touch panel input unit 23 has detected an input (step S13). In the flowchart, the processing loops until an input is detected (“No” in step S13), but this is for easy understanding of the flowchart, and other processing is actually performed in parallel during that time. The CPU 31 performs multitask processing.

  When the user's finger 51 touches the display panel 13, an input is detected by the touch panel input unit 23 ("Yes" in step S13). In response to this, the CPU 31 acquires the position where the input has been made from the touch panel input unit 23 (step S15). The input position is acquired as, for example, coordinates in the vertical direction (Y direction) and the horizontal direction (X direction) of the display panel 13.

  Subsequently, the CPU 31 determines whether or not there is a display component related to the operation at the acquired input position (step S17). Here, the display component related to the operation should respond when an operation such as touching the display component is performed. Examples of such display components are the operation buttons and the “cancel” button 42 constituting the alphabet keys shown in FIG. Another example is the “End” button 48 in the setting menu of FIG. 6, a drop-down list for setting the shift direction, a character input window for inputting the shift amount, and a check box for setting presence / absence of animation display.

  If the display component is not present at the input position (“NO” in step S17), the routine returns to step S13 and waits for a new input. On the other hand, when the display component is present at the input position (“No” in step S17), the CPU 31 stores TRUE (1) in the temporary variable input (step S19). The temporary variable input is a storage area secured on the RAM 35 and takes a value of TRUE (1) or FALSE (zero). The initial value is FALSE.

Further, the CPU 31 stores the value of the variable T in the temporary variable t (step S21). The temporary variable t is a storage area secured on the RAM 35. The variable T is the animation display time acquired in step S11. The temporary variable t is used as an animation display counter.
Then, the CPU 31 highlights the operated display component (step S23). A specific example of highlighting is the “S” button in FIG.

  Subsequently, the CPU 31 determines whether or not the input has continued beyond a predetermined first period (step S25). If the first period has not yet been exceeded (“No” in step S25), it is checked whether the input continues (step S27). If the input continues, the routine returns to step S25 and loops through steps S25 and S27 until the first period has elapsed. When there is no input before the first period has elapsed (“Yes” in step S27), the routine proceeds to step S65, which will be described later, and performs processing according to the input without performing screen shift display.

If the input continues beyond the first period (“Yes” in step S25), the CPU 31 calculates the shift amount of the display panel 13 in the X direction and the Y direction based on the values of the variables D and S, and the temporary variable X And Y are stored (step S29). Temporary variables X and Y are storage areas secured on the RAM 35. The variables D and S correspond to the items “shift direction” and “shift amount” in the setting menu of FIG.
When “screen center” is set as the “shift direction”, the shift direction changes according to the input position, so the values of X and Y, which are components in the X direction and Y direction, also change. The CPU 31 calculates X and Y values according to the input position.

  When the setting of “shift direction” is “far from the screen edge”, the CPU 31 determines which edge of the screen is closest to the top, bottom, left, and right of the screen, and shifts by the shift amount set to the opposite side. Set the values of X and Y so that Further, when the “shift direction” is set to the upward direction, the left direction, the right direction, or the downward direction, the value of X or Y is set so that the shift amount is shifted by the set shift amount. For example, when the shift amount is set to 50 pixels and the shift direction is set to the upward direction, X = 0 (zero) and Y = 50 are set. On the other hand, when the shift direction is downward, Y = −50.

  Next, the CPU 31 determines whether or not to perform animation display (step S41). This determination is based on whether the value of the variable T is zero. When animation display is not performed (“No” in step S41), the display on the screen is shifted all at once by X in the right direction and Y in the upward direction (step S43). Thereafter, the routine proceeds to step S57 described later.

  On the other hand, when displaying an animation (“Yes” in step S41), the CPU 31 stores a value obtained by dividing the variable X by the variable T in the temporary variable dx (step S45). Further, a value obtained by dividing the variable Y by the variable T is stored in the temporary variable dy (step S47). Here, the variables dx and dy are storage areas respectively secured on the RAM 35. dx and dy are amounts to be shifted in the X direction and the Y direction in one frame of the animation.

  Thereafter, the CPU 31 determines whether or not the animation display has ended, that is, whether or not the temporary variable t has become zero (step S49 in FIG. 8). If not completed (“No” in step S49), the screen display is shifted by dx pixels in the X direction and dy pixels in the Y direction (step S51), and a time for one frame is waited (step S53). The value of the temporary variable t is decreased by 1 (step S55).

  Subsequently, the CPU 31 acquires the current input position from the touch panel input unit (step S57). If there is no input (step S59), the routine proceeds to step S65 described later. If the input continues ("No" in step S59), the CPU 31 determines whether or not the input position is the same as before (step S61). If so, the routine returns to step S49 and continues the animation. If there is a change in the input position (“No” in step S61), FALSE is stored in the temporary variable input (step S63). The contents of Input are used to determine whether or not to perform processing according to the input in subsequent steps S69 and S71. That is, if the input position changes during the process, it is determined that the user has corrected the input as shown in FIG. 7B, and the process corresponding to the input before the movement is not performed.

  Subsequently, the routine proceeds to step S65. Here, processing is performed when there is no input or when the position of the input changes. The CPU 31 stops highlighting the selected display component (step S65). Then, the shift of the screen display is returned to the original state (step S67). Note that animation display may also be performed when the shift is restored, but the flowchart omits animation processing for the sake of simplicity.

Further, the CPU 31 checks whether or not the value of the temporary variable input is FALSE (step S69). In the case of normal input, the value of the temporary variable “input” holds TRUE stored in step S19. In that case (“No” in step S69), the routine proceeds to step S71 and performs a process according to the input (step S71). The process corresponding to the input is, for example, the following process in the scene shown in FIG. When the finger is released after the “S” button is selected, the character input “S” is accepted. At that time, the CPU 31 performs processing for displaying “S” in the message display area 43, moving the cursor to the right, and adding “S” as a message to the message storage area secured in the RAM 35.
Thereafter, the routine returns to step S13 and waits for the next input.

On the other hand, FALSE is stored in the temporary variable input when the input should be corrected corresponding to the movement of the finger 51 as shown in FIG. In this case (“Yes” in step S69), the routine skips step S71 and returns to step S13.
The above is the processing of the CPU 31.
