The smartphone 1 as thus constituted displays a virtual keyboard on the touch-screen display 2, when a document is edited by a character input application (for example, a document preparation application such as a memo pad application). In response to detecting a touch to the virtual keyboard, the smartphone 1 inputs a character displayed in a position of the virtual keyboard, the touch to which was detected.

By maintaining the displaying of the virtual keyboard when editing a document with a character input application, the smartphone 1 can reduce the processing load for opening the document, and can improve the operability for editing the document. Descriptions are hereinafter provided for specific processing.

FIGS. 6(
a) to 6(g) are diagrams showing a display screen 60 that is displayed on the touch-screen display 2 when a document is edited with the character input application. Here, the display screen 60 means the entire display area of the touch-screen display 2.

As shown in FIG. 6(a), when a document is edited with the character input application, the controller 10 displays a document area 61 and a virtual keyboard 62 on the display screen 60. The controller 10 displays the document area 61 in an upper area of the display screen 60, and displays the virtual keyboard 62 in a lower area of the display screen 60.

In response to a touch to the virtual keyboard 62 by a user U, the controller 10 displays a character corresponding to the point thus touched, in the document area 61.

As shown in FIGS. 6(a) and 6(b), when the controller 10 detects a flick in the document area 61 by the user U, the controller 10 terminates the editing document displayed in the document area 61, and performs displaying such that the entire document displayed in the document area 61 moves in a direction of the flick.

In the example shown in FIG. 6(b), when the controller 10 detects a flick, the controller 10 terminates the editing document displayed in the document area 61, and performs displaying such that the document displayed in the document area 61 moves to the left.

After displaying such an effect, the controller 10 displays a dialog box 63 for confirming whether the document should be stored, the dialog box 63 being superimposed on the document area 61, as shown in FIG. 6(c). When a touch to “YES” in the dialog box 63 is detected, the controller 10 stores the currently edited document into the storage 9, and displays a message box 64 indicating that the currently edited document is stored into the storage 9, the message box 64 being superimposed on the document area 61 (see FIG. 6(d)). The controller 10 then displays a new document in the document area 61 (see FIG. 6(e)). The new document is, for example, a blank document.

When a touch to “NO” in the dialog box 63 is detected, the controller 10 discards data of the currently edited document, and displays a new document in the document area 61 (see FIG. 6(e)).

In the example shown in FIGS. 6(c) and 6(d), the controller 10 displays the dialog box 63 and the message box 64 in order to confirm whether the document should be stored. However, the document may be automatically stored into the storage without confirming whether the document should be stored.

As shown in FIGS. 6(a) to 6(e) described above, when the controller 10 terminates the editing document displayed in the document area 61, and a touch operation to switch the editing document over from a first document to a new document is performed, the controller 10 maintains displaying of the virtual keyboard 62 while switching the editing document over from the first document to the new document.

In general, in a device that displays a virtual keyboard on a touch-screen display, when the editing document displayed in a display area is terminated, and an operation to switch over to the editing of another document is performed, the displaying of the virtual keyboard is temporarily cancelled. As a result, when the editing is switched over to the editing of a new document, the type of characters to be input by the virtual keyboard that was displayed before the switching over may be changed. As an example in which the type of characters is changed, there is a conceivable case in which a type of characters is changed to that of default setting such that, for example, Japanese hiragana or katakana characters are changed to alphabetic characters. In this case, each time a document is switched over to a new document, the user has been required to change the type of characters.

On the other hand, with the smartphone 1 according to the present embodiment, the editing document displayed in the document area 61 is switched the editing document over from a first document to a new document, while maintaining the displaying of the virtual keyboard 62. As a result, since the smartphone 1 maintains the displaying of the virtual keyboard 62 that is easy for the user to input characters, the smartphone 1 can reduce the processing load when a document is opened. The user does not have to change the type of characters, and the operability for editing a new document is improved.

After an operation to switch over to the editing of a new document is performed, while the editing of the document displayed in the document area 61 is switched over to the editing of a new document, the controller 10 maintains the displaying of the virtual keyboard 62. For example, an example of an operation to switch over to the editing of a new document is a flick in the document area 61. As shown in FIG. 6(f), while switching over to the editing of a new document, the controller 10 stores data of characters that are input via the virtual keyboard 62, into the storage 9. Upon completion of the switching over to the editing of a new document, the controller 10 displays the data of the characters stored in the storage 9, in the document area 61. In this way, with the smartphone 1, characters can be input while the editing of the document displayed in the document area 61 is switched over to the editing of a new document; therefore, the operability for editing a new document is further improved.

When the controller 10 detects a flick in the document area 61 as an operation to switch over to the editing of a new document, the editing of the currently edited document is switched over to the editing of a new document, while maintaining the displaying of the virtual keyboard 62. Therefore, the smartphone 1 can switch over to the editing of a new document without performing any operations on the virtual keyboard 62 that is desired to be continuously displayed, and the processing load for opening a document can be reduced. The user can intuitively perform an operation to switch over to the editing of a new document.

As shown in FIG. 6(g), when a gesture of covering the entirety of the display screen 60 of the touch-screen display 2 is detected, the controller 10 terminates the character input application that edits documents. In this case, the controller 10 may automatically store the currently edited document into the storage 9, or the controller 10 may automatically discard the currently edited document. The gesture of covering the entirety of the display screen 60 is an example, and the character input application for editing documents may be terminated in response to detecting any other gesture. In this way, since the smartphone 1 terminates the character input application for editing documents in response to detecting a predetermined gesture, the user can intuitively edit documents.

In the above descriptions, the controller 10 switches over from the editing of the currently edited document to the editing of a new document, but the switching over is not limited to the switching over to a new document. For example, the controller 10 may switch over from the editing of the currently edited document to the editing of any other document. For example, in a state where two documents are currently edited and while being switched over, when the controller 10 detects a leftward flick in the document area 61, one document may be switched over to another document, while maintaining the displaying of the virtual keyboard 62. Furthermore, in this case, when the controller 10 detects a rightward flick in the document area 61, the editing of the two currently edited documents may be switched over to the editing of a new document, while maintaining the displaying of the virtual keyboard 62.

Next, with reference to a flowchart shown in FIG. 7, descriptions are provided for a flow of processing when the smartphone 1 edits documents with the character input application.

In Step ST1, the controller 10 activates the character input application stored in the storage 9, and displays the document area 61 and the virtual keyboard 62 on the touch-screen display 2.

In Step ST2, the controller 10 detects a flick in the document area 61 by the user U.

In Step ST3, the controller 10 terminates the editing of the document displayed in the document area 61, and performs displaying such that the document displayed in the document area 61 moves in a direction of the flick. The controller 10 switches over from the editing of the document displayed in the document area 61 to the editing of a new document, while maintaining the displaying of the virtual keyboard 62.

After displaying such an effect, in Step ST4, the controller 10 displays the dialog box 63 for confirming whether the document should be stored, the dialog box 63 being superimposed on the document area 61.

In Step ST5, the controller 10 determines whether a touch to any one of “YES” or “NO” in the dialog box 63 was detected, i.e. whether the document should be stored. In a case in which the touch to “YES” was detected, i.e. in a case in which the document should be stored, the controller 10 advances the processing to Step ST6. In a case in which the touch to “NO” was detected, i.e. in a case in which the document should be discarded, the controller 10 advances the processing to Step ST7.

In Step ST6, the controller 10 stores data of the currently edited document into the storage 9, and displays the message box 64 indicating that the currently edited document is stored into the storage 9, the message box 64 being superimposed on the document area 61.

In Step ST7, the controller 10 discards the data of the currently edited document. In a case in which a character is input via the virtual keyboard 62 during Steps ST3 to ST7, i.e. while switching over from the editing of the document displayed in the document area 61 to the editing of a new document, the controller 10 stores data of the input character into the storage 9.

In Step ST8, the controller 10 displays a new document in the document area 61, while maintaining the displaying of the virtual keyboard 62. Here, in a case in which a character is input via the virtual keyboard 62 during Steps ST3 to ST7, the controller 10 displays the data of the character stored in the storage 9, in the document area 61.

In Step ST9, in a case in which a gesture of covering the entirety of the display screen 60 of the touch-screen display 2 is detected in a state of any one of Steps ST1 to ST8, the controller 10 terminates the character input application for editing documents, and terminates the processing shown in the present flowchart.

Therefore, the smartphone 1 switches over from the editing of the document displayed in the document display area 61 to the editing of a new document, while maintaining the displaying of the virtual keyboard 62. As a result, since the smartphone 1 maintains the displaying of the virtual keyboard 62 that is easy for the user to input characters, the smartphone 1 reduces the processing load when a document is opened. The user does not have to change the type of virtual keyboards, and the operability for editing a new document is improved.

A part or all of the programs stored in the storage 9 as described in FIG. 5 may be downloaded from other devices via wireless communication by the communication unit 6. A part or all of the programs stored in the storage 9 as described in FIG. 5 may be stored in a storage medium that is readable by a reader included in the storage 9. A part or all of the programs stored in the storage 9 as described in FIG. 5 may be stored in a storage medium such as a CD, a DVD or a Blu-ray that is readable by a reader connected to the external interface 14.

The configuration of the smartphone 1 shown in FIG. 5 is an example, and may be altered as appropriate within the scope without departing from the spirit of the present invention. For example, the number and type of the button(s) 3 are not limited to the example shown in FIG. 5. For example, the smartphone 1 may include buttons with a numeric keypad layout or a QWERTY keyboard layout, in place of the buttons 3A to 3C, as buttons for operations regarding screens. The smartphone 1 may include only a single button and may not include any button, for operations regarding screens.
