Description

  The present invention relates to an information processing apparatus capable of inputting a character input instruction using a display panel provided with a touch panel.

In recent years, a keyboard with a QWERTY layout has been proposed in which key display layouts are displayed in alphabetical order or displayed in alphabetical order for key input (see, for example, Patent Document 1).
JP 2001-222362 A

By the way, unlike a computer keyboard, the touch panel does not feel uneven, and the position and size of each key slightly differ depending on the size of the touch panel display screen.
For this reason, it is difficult for a person familiar with a computer to input a key without following the key. Therefore, at the time of key input, it is necessary to confirm the input by moving the line of sight to the input character display unit displaying the input character while keeping the line of sight on the key.

  However, in the prior art, since the distance between the key and the input character display portion is large, the movement of the line of sight increases and the eyes become tired, so that there is a problem that an input mistake is likely to occur. In particular, when the alphabet is once input and converted into kanji or hiragana, such as romaji input, the line of sight is moved beyond the number of characters actually displayed, and eye fatigue and input mistakes are likely to occur.

  The present invention has been made in view of the above points, and an object of the present invention is to provide an information processing apparatus capable of reducing eye movement and reducing eye fatigue and input errors.

  In order to solve the above-described problems, the present invention is an information processing apparatus including a display unit that displays a virtual keyboard having a predetermined arrangement, and a touch panel type input unit provided on a display surface of the display unit. The character of the virtual keyboard corresponding to the touched position of the input means and the touch character recognition means for specifying the array row to which the character belongs, and the input character display area for displaying the character are input. And a display position control means for changing the key layout of the virtual keyboard and the display position of the input character display area so as to be located immediately above the character key.

  Further, the present invention is characterized in that the display position control means changes the key layout of the virtual keyboard in the vertical direction of the screen and changes the input character display area in the horizontal direction of the screen. To do.

  According to this invention, the touch character recognition means identifies the character of the virtual keyboard corresponding to the touched position of the input means and the array row to which the character belongs, and the display position control means displays the character. The key arrangement of the virtual keyboard and the display position of the input character display area are changed so that the input character display area to be positioned is located immediately above the key of the input character. Therefore, the distance between the touched key and the input character display area is reduced, the movement of the line of sight can be reduced, and the advantages of reducing eye fatigue and input mistakes can be obtained.

  Hereinafter, an information processing apparatus (part) according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic block diagram showing a partial configuration of an information processing apparatus according to an embodiment of the present invention.
The display unit 10 includes a CRT, a liquid crystal display, and the like, and displays a virtual keyboard described later in this embodiment. The touch panel 12 is a touch panel formed of a substantially transparent material provided on the front surface of the display unit 10. The control unit 14 executes various types of information processing according to a predetermined control program. In particular, in the present embodiment, a virtual keyboard is displayed on the display unit 10, and character input from the user is accepted according to the touched location on the touch panel 12 and the display state of the display unit 10.

Next, FIG. 2 is a schematic diagram illustrating an example of a virtual keyboard in the information processing apparatus according to the present embodiment.
In the figure, the virtual keyboard 20 is displayed on the display unit 10. The virtual keyboard 20 is displayed in a QWERTY layout like a general keyboard, but is not limited to this and may be in the order of 50 notes or alphabet. Keys belonging to the same row are set in one group as indicated by a dotted line. For example, “shift”, “Z”, “X”,..., “\” Belong to the first line, “A”, “S”, ..., “]” waves, belong to the second line, “Q”, “W”,..., “[” Belong to the third row, and “1”, “2”,..., “¥” belong to the fourth row. The input character display area 22 is an area for displaying characters touch-input by the user.

  The user touches a character to be input from the virtual keyboard 20 displayed on the display unit 10. At this time, the control unit 14 specifies the character corresponding to the touched position and the array row (the vertical position in FIG. 2) to which the character belongs, and also the column to which the character belongs (the horizontal direction in FIG. 2). 2), the key arrangement is changed up and down in FIG. 2 so that the input character display area 22 is positioned immediately above the input key so that the user's line of sight movement is minimized. The display position of the character display area 22 is changed to the left and right in FIG.

Next, the operation of the information processing apparatus described above will be described.
Here, FIG. 3 is a flowchart for explaining the touch panel key input process of the information processing apparatus according to the present embodiment.

  When key input by the virtual keyboard 20 is designated, first, the virtual keyboard 20 is displayed on the display unit 10 in the initial arrangement shown in FIG. 2 (step S10). In this initial arrangement, the input character display area 22 is arranged at the top. Next, it is determined whether or not there is an instruction to end the key input from the virtual keyboard 20 (for example, touching the “input end” key in FIG. 2) (step S12). Then, when there is an instruction to end the input, the process ends.

  On the other hand, if the input has not ended, it is determined whether or not another key input (touch) has been made (step S14). If there is no key input, the process returns to step S12 and the above-described processing is repeated. On the other hand, when any key is input, the key to which the input character display area 22 is input belongs in order to place the input character display area 22 immediately above the input (touched) key. The key arrangement is changed up and down in FIG. 2 so as to be arranged immediately above the arrangement row, and the position of the input character display area 22 is changed to the left and right in FIG. 2 (step S16), and the input (touched) character is input. It is displayed in the character display area 22 (step S18). Then, the process returns to step S10, the virtual keyboard 20 is displayed in the initial arrangement as shown in FIG. 2, and the above-described processing is repeated thereafter.

  For example, in the initial arrangement state shown in FIG. 4A, when the first row key (the “C” key in the illustrated example) indicated by a dotted line is touched as shown in FIG. The key arrangement is changed so that the input character display area 22 is arranged immediately above the touched arrangement line. Furthermore, as shown in FIG. 4C, the display position of the input character (“C” in the illustrated example) in the input character display area 22 is the key of the input character (“C” in the illustrated example). The position of the input character display area 22 is changed in the left-right direction so that it is directly above the key. Thereafter, as shown in FIG. Similarly, in the initial arrangement state shown in FIG. 5 (a), as shown in FIG. 5 (b), when the second row key (in the example shown, the “H” key) indicated by the dotted line is touched, The key layout is changed so that the input character display area 22 is immediately placed immediately above the touched array row, and the input character ("H" in the illustrated example) is further changed as shown in FIG. The position of the input character display area 22 is changed so that the display position is directly above the key of the input character (“H” key in the illustrated example). Thereafter, the initial array is restored as shown in FIG.

  Further, in the initial arrangement state shown in FIG. 6A, when the third row key (in the illustrated example, “I” key) indicated by a dotted line is touched as shown in FIG. The key layout is changed so that the input character display area 22 is arranged immediately above the touched array row, and the input characters ("I" in the illustrated example) are displayed as shown in FIG. The position of the input character display area 22 is changed so that the position is directly above the key of the input character (in the example shown, the “I” key). Thereafter, as shown in FIG.

  According to the above-described embodiment, since the key arrangement is changed so that the input character display area 22 is arranged immediately above the key touched by the user, the input character for confirming the touched key and its input result. The distance from the display area 22 can be shortened. As a result, the user's line-of-sight movement can be reduced, and eye fatigue and input errors can be reduced.

  The control unit 14 includes a memory, a CPU (central processing unit), and the like, and a non-volatile program that records a program (not shown) for realizing the process of the control unit 14 described above. It is assumed that the function is realized by loading the memory from a memory, a magnetic disk, or the like and executing it.
