As shown in FIG. 4, the first line kana character (!) May be displayed in the first line kana character display window 103i. Also, as shown in FIG. 4, a delete key (Delete) may be displayed in the first line kana character display window 103i. In this case, when the user taps the delete key (Delete), one character is deleted from the input information display window 103h. A view of the touch pad 104 viewed from the back side of the information processing apparatus 100 is shown on the right side of FIG.

  FIG. 5 is an explanatory diagram (part 2) for explaining the function of the control unit of the information processing apparatus according to the embodiment of the present invention. Hereinafter, the function of the control unit of the information processing apparatus according to the embodiment of the present invention will be described with reference to FIG. 5 (see FIGS. 1 to 3 as appropriate).

  As illustrated in FIG. 5, it is assumed that the user taps the first line kana character (NA) displayed in the first line kana character display window 103i by the first contact unit 210. Then, the touch panel 103 acquires information indicating the position where the first line kana character (NA) is displayed as the first position information. When the touch panel 103 acquires the first position information, the control unit displays the first line kana character displayed at the position indicated by the first position information among the first line kana characters displayed on the touch panel 103. It is determined that it was selected by. In the input information display window 103h, information input by the user (inside of them) is displayed.

  When the control unit determines that the first row kana character (NA) is selected by the user, the control unit determines the column kana character group (NA, N, N, N, NO) associated with the first row Kana character (NA), Obtained from the storage unit and displayed via the touch panel 103. An example of the displayed screen is shown as a column kana character display screen 103b. The column kana character display screen 103b includes a column kana character group display window 103j, and the column kana character group display window 103j displays a column kana character group (Nana, N, N, N, N). At this time, since the control unit determines that the first row kana character (na) is selected by the user, the column kana character (na) matching the first row kana character (na) is displayed as a large character, and the others The column kana characters (N, N, N, N) are displayed as small characters. However, the size of the characters to be displayed is not particularly limited, and all the column kana character groups (nana, nu, ne, no) may be displayed as characters of the same size.

  In addition, here, the control unit displays the column kana character groups (na, ni, n, ne, and so on) side by side in the vertical direction. The direction for displaying is not limited to the vertical direction. For example, it may be displayed in a line from the upper left to the lower right, or may be divided into two or more lines.

  FIG. 6 is an explanatory diagram (part 3) illustrating the function of the control unit of the information processing apparatus according to the embodiment of the present invention. Hereinafter, the function of the control unit of the information processing apparatus according to the embodiment of the present invention will be described with reference to FIG. 6 (see FIGS. 1 to 3 as appropriate).

  As shown in FIG. 6, in a state where the first contact unit 210 is tapping the first row kana character (NA) displayed in the first row kana character display window 103i, the second contact unit 220 is touched with the touchpad. Suppose that it moved, contacting with the 2nd contact surface 104a of 104. FIG. An operation in which the user moves the second contact unit 220 while making contact with the second contact surface 104a of the touch pad 104 is also referred to as a drag operation. Then, the touch pad 104 acquires second position information indicating a contact position with the second contact portion 220 on the second contact surface 104a.

  When the touch pad 104 acquires the second position information, the control unit displays movement information indicating a direction and a distance moved while the second contact unit 220 is in contact with the second contact surface 104a based on the second position information. get. Based on the acquired movement information, the control unit scrolls the column kana character group displayed on the touch panel 103. In the example illustrated in FIG. 6, the second contact portion 220 moves downward by a distance d1 while contacting the second contact surface 104a. Therefore, the control unit scrolls, for example, the column kana character group displayed in the column kana character group display window 103j in the downward direction by a distance proportional to the distance d1. Let In addition, as a result of scrolling the column kana character group (na, n, n, ne), the column kana character (na) deviates from the vicinity of the contact position between the first contact portion 210 and the first contact surface 102a. As shown in FIG. 6, the control unit may display the column kana characters (na) with small characters. In addition, the control unit displays the column kana character (ne) in a large character because the column kana character (ne) is located near the contact position between the first contact unit 210 and the first contact surface 102a. It is good. The column kana characters near the contact position between the first contact portion 210 and the first contact surface 102a are in the active state.

  In the example shown in FIG. 6, the column kana character group (na, ni, ne, no) is scrolled only in the vertical direction. As described above, the scrolling direction may be limited only to a predetermined direction (for example, the vertical direction or the horizontal direction). In such a case, the control unit needs to approximate the direction in which the user moves the second contact unit 220 while making contact with the second contact surface 104a of the touch pad 104 to a predetermined direction. For example, the control unit approximates the direction in which the second contact unit 220 is moved while being in contact with the second contact surface 104a of the touch pad 104 to the closest direction among the predetermined directions. For example, when the direction in which the user moves the second contact unit 220 while touching the second contact surface 104a of the touch pad 104 is the lower right direction, the lower left direction, or the like, the control unit approximates the lower direction. To do. Further, for example, the control unit approximates the upper direction when the direction in which the user moves the second contact unit 220 while contacting the second contact surface 104a of the touch pad 104 is the upper right direction and the upper left direction. To do.

  It is assumed that the control unit scrolls the column kana character group displayed in the column kana character group display window 103j based on the movement information, and the first contact unit 210 is separated from the first contact surface 102a of the touch panel 103. In this case, the control unit determines that a column kana character that has been activated is selected from the column kana character group displayed in the column kana character group display window 103j, and inputs the column kana character as input information. It is good also as displaying on the display window 103h. For example, after displaying the column kana characters in the input information display window 103h, the control unit displays the first row kana character display window 103i on the touch panel 103 so that the user can select the first row kana characters. Good.

  In the example illustrated in FIG. 6, it is assumed that the user moves the first contact unit 210 away from the first contact surface 102 a of the touch panel 103 in a state where the first contact unit 210 is in contact with the string kana character (ne). In this case, the control unit determines that the column kana character (ne) has been selected by the user, and displays the column kana character (ne) in the input information display window 103h.

  The control unit, for example, saves information displayed in the input information display window 103h in a storage unit or transmits it to another apparatus via a communication unit (not shown) by a user's button operation or touch panel 103 operation. Or printing on paper via a printer (not shown).

  Here, when the second contact unit 220 moves while being in contact with the second contact surface 104a of the touch pad 104 while the first contact unit 210 is tapping the first row kana character (na), The control unit scrolls the column kana character group display window 103j. However, the timing at which the control unit scrolls the column kana character group display window 103j is not limited to this. For example, it is assumed that the first contact part 210 has tapped the first line kana character (NA) displayed in the first line kana character display window 103i once. In that case, it is possible that the column kana character group display window 103j corresponding to the tapped first row kana character (na) can be scrolled without the first contact portion 210 continuing to tap.

  In this case, the control unit scrolls the column kana character group displayed in the column kana character group display window 103j based on the movement information even if the first contact unit 210 does not keep tapping. Then, it is assumed that the first contact portion 210 has been tapped again. In this case, the control unit determines that a column kana character that has been activated is selected from the column kana character group displayed in the column kana character group display window 103j, and inputs the column kana character as input information. It is good also as displaying on the display window 103h.

  FIG. 7 is an explanatory diagram (part 4) illustrating the function of the control unit of the information processing apparatus according to the embodiment of the present invention. Hereinafter, the function of the control unit of the information processing apparatus according to the embodiment of the present invention will be described with reference to FIG. 7 (see FIGS. 1 to 3 as appropriate).

  As shown in FIG. 7, the control unit may display a predictive conversion result display window 103k in the column kana character display screen 103b. In that case, the control unit displays the predicted conversion result derived from the activated column kana character among the column kana character groups displayed in the column kana character group display window 103j. It may be displayed on the screen. In that case, a program for deriving the prediction conversion result from the column kana character is stored in the storage unit, and the control unit outputs the prediction conversion result by executing the program.

[4. Operation of information processing apparatus]
FIG. 8 is a flowchart showing the operation of the information processing apparatus according to the embodiment of the present invention. Hereinafter, the operation of the information processing apparatus according to the embodiment of the present invention will be described with reference to FIG. 8 (see FIGS. 1 to 7 as appropriate).

  First, when the application is activated, the control unit generates a thread that continues to monitor whether the first line kana character display window 103i has been tapped. Among them, the control unit determines whether or not a tap is performed on the surface of the first line kana character display window 103i (step S1). When the control unit determines that the tap is not performed (“No” in step S1), the control unit returns to step S1. If the control unit determines that the tapping has been performed (“Yes” in step S1), the control unit displays the column kana characters belonging to the first row kana characters selected by the tapping in the column kana character group display window 103j (step k). S2). Specifically, if the tapped area is an area on the keyboard, the control unit expands the tapped key over the entire keyboard.

  Next, the control unit determines whether or not the touch pad 104 on the back surface is dragged in a state where the tapping is continued (step S3). When the control unit determines that it is not dragged (“No” in step S3), the control unit returns to step S1. If the control unit determines that it has been dragged (“Yes” in step S3), it scrolls the displayed character string (step S4) and returns to step S1. As an example, the user's second contact unit 220 taps an arbitrary place on the touch pad 104 and drags it in an arbitrary direction as shown in the lower diagram of FIG. If the drag direction is upward from the tap point, the control unit scrolls the column kana character group display window 103j displaying the column kana characters belonging to the first line kana characters on the front surface upward. If the drag direction is downward from the tap point, the control unit scrolls the column kana character group display window 103j downward.

The scroll distance is proportional to the stroke distance from the position where the touch pad 104 on the back surface is tapped. As an example, “NA” shown in the upper diagram of FIG. 6 is scrolled and displayed as “NE” shown in the lower diagram of FIG. As long as the front touch panel 103 is continuously tapped, the column kana character group display window 103j of the front touch panel 103 is scrolled as much as the drag of the back touch pad 104 is repeated. Since the scrolling does not depend on the tap position of the touch panel 103 on the front surface, for example, when the tap position is at the bottom of the screen, it is possible to avoid the problem of being unable to drag (= scroll) further down.
Further, for example, in the multi-window system, if the active window is clear, it is possible to scroll the active window only by dragging the touch pad 104 on the back surface without tapping the touch panel 103 on the front surface.

[5. Effects of this embodiment]
In the information processing device, when the first row kana characters displayed on the touch panel are tapped, column kana characters belonging to the first row kana characters, muddy characters, and prediction conversion results are displayed, and the number of items in the list has become enormous. You can also scroll if you tap the bottom edge of the screen. As a result, it is possible to effectively use a limited area such as a touch panel of a mobile device or the like and realize scrolling that is not limited by the area.

  This embodiment can be applied to all lists having a parent-child relationship. For example, in title selection of music content, a list of initial letters of alphabet (for example, 'a', 'b', 'c', etc.) is displayed on the touch panel. Here, while tapping any item in the initials list, a list of music titles corresponding to the initials of the alphabet (for example, those starting with 'a') is displayed, and dragging on the reverse side of the music title list Scroll. As a result, a high-speed search for music content can be realized. In addition, the content is not limited to music content, and high-speed search can be realized similarly for content having a title such as video content.

  In addition, a list of dictionary headwords (for example, words starting with 'a') may be displayed on the touch panel. In that case, while tapping any item of the dictionary entry word, the explanation of the word (for example, explanation of “apple”) is displayed on the touch panel by a pop-up display or the like, and the explanation scrolled by dragging on the back surface is displayed. I do. As a result, only the explanation of the headword selected by the user is displayed, so even if the explanation of each headword is long and cannot be displayed in the small area touch panel, the explanation of the headword is searched at high speed. can do. The present invention is not limited to a dictionary, and can be applied to a case where a user selects a headword by tapping and scrolls a sentence or the like corresponding to the selected headword by dragging.

  Moreover, it is good also as displaying a map (for example, world map) on a touch panel. In that case, while tapping an arbitrary area in the map, store information existing in that area (for example, store information existing in 'Japan') is displayed on the touch panel by a pop-up display or the like, and is displayed by dragging on the back surface. Scroll information. As a result, only the store information existing in the area selected by the user is displayed, so even if the store information is long and cannot be displayed in a small area touch panel, the store information can be searched at high speed. . Moreover, it is not limited to store information, It can apply when making a user select an area with a tap and scrolling the information relevant to the selected area by dragging.

  In this embodiment, the scroll distance of the display content is determined by the relative distance from an arbitrary point on the touch pad on the back surface. Therefore, it is possible to avoid the problem that it is difficult for the user to scroll the display contents depending on the angle with the device.

  In the present embodiment, the scroll portion (touch pad 104) can be separated from the LCD screen (touch panel 103). Accordingly, it is possible to avoid the restriction that dragging is difficult when a material that is difficult to slip (for example, an elastic material such as a rubber material) is used as the material of the LCD screen.

  Conventionally, there is a technique for performing scrolling by dragging the touch pad on the back surface. However, the selection of an object to be scrolled is based on selection by a hardware button, pointing to a touch panel on the back surface, or the like. Therefore, for example, when there are 500 objects in the LCD screen (for example, when selecting a city in an application such as a map viewer and selecting information related to the selected city by scrolling the list), The act of selecting with a hardware button or moving the cursor with a touch panel on the back is not an easy operation.

  On the other hand, in the present embodiment, the touch panel on the front surface can be used to scroll “only while tapping” or “to the object being tapped” with the touch pad on the back surface. As a result, object selection and scrolling can be performed simultaneously, and the scanning speed is high. Also, operations such as dragging the touchpad on the front surface are used to assist in object selection (for example, selecting an object by dragging the front surface touch panel, zooming for easy selection of the entire screen by long-pressing the front surface touch panel, etc.). There is a special effect that can be.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention.
