Abstract

PROBLEM TO BE SOLVED: To provide a device by which, when erroneous input is performed in touch panel operation, it can be corrected to a desired input quickly and easily.SOLUTION: In a display device 100 with position input means, when slide operation is performed through a key for cancellation of input of a position, the input of the position is canceled, and input of a position around the position and in the slide direction is performed, thereby performing cancellation and re-input by one operation.

Description

The present invention relates to a display device and a display method for correcting input of position coordinates and the like.

  Products such as a smartphone equipped with a touch panel are known that operate by touching a relatively small screen with a finger or the like. In such a small terminal, since the area for display and operation is limited, each button display must be reduced and the interval between them must be reduced. For this reason, when a certain button is pressed, a button adjacent to the button may be erroneously pressed. In this case, in order to correct the error, two kinds of operations are required in which the result caused by the incorrect input is restored and then the correct button is pressed again.

  For example, in the case of input using a software keyboard according to the prior art, if an adjacent character is accidentally input, it is necessary to delete the character by pressing the delete key once and then input the correct character again.

  Also, for example, when browsing the web with a smartphone web browser, if you accidentally select a link adjacent to the target link, you had to press the correct link again after pressing the return button. .

As a method for preventing such an erroneous input, as in Patent Document 1, when touch input to the touch panel is turned on, the peripheral portion thereof is enlarged and displayed according to the touch position when the touch is turned off. Thus, even when the touch position is deviated, it is considered that accurate input can be performed by depressing and holding a finger or the like.

Japanese Patent No. 2623787

  However, the apparatus described in Patent Document 1 requires operations such as touch-on, position confirmation, and touch-off for each input, and thus is not suitable for quick input. In addition, if an erroneous input is performed, it is necessary to perform two operations of deletion and re-input.

Therefore, the present invention is not intended to prevent erroneous input in advance in order to deal with the problem of erroneous input in touch operation or the like, but corrects to a desired input quickly and easily when erroneous input is performed. An object is to provide an apparatus capable of performing the above.

  In order to solve the above-mentioned problem, a first display device according to the present invention includes an input correction unit that cancels position input and inputs positions around the position in a display device including position input means. It is characterized by that.

  This makes it possible to quickly and easily correct an erroneous input by a peripheral key or the like.

  According to a second display device of the present invention, in addition to the configuration of the first invention, the input correction unit cancels the input of the position when a slide operation is performed from a key for canceling the input of the position. It is characterized in that a position in the direction of the periphery and the slide is input.

  Thus, correction can be performed by an intuitive method of sliding the key to be corrected in a certain direction.

  According to a third display device of the present invention, in addition to the configuration of the first invention, the input correction means cancels the position input when a slide operation is performed from the position continuously after the position input. A position around the position and in the direction of the slide is inputted.

  This eliminates the need to move an operating body such as a finger to the key to be canceled, and enables quick correction.

  According to a fourth display device of the present invention, in addition to the configuration of the first invention, the input correction unit is configured to input the position after the position is input and immediately after the position where the position input result is displayed. When a slide operation is performed from the position, the input of the position is canceled, and a position around the position and in the direction of the slide is input.

  Thereby, even when not immediately after the input, if the cursor is moved to the character to be corrected, the correction by the slide becomes possible.

  According to a fifth display device of the present invention, in addition to the configuration of the first invention, the input correction means cancels the input of the position when a slide operation is performed from the display position of the result of the position input, A position around the position and in the direction of the slide is input.

  This makes it possible to correct the input with a single operation by sliding from the display location of the input result to be corrected.

  According to a sixth display device of the present invention, in addition to the configuration of the first invention, the input correction means cancels the input of the position when the display device is tilted in a specific direction, It is characterized by inputting a position in a specific direction.

  Thereby, intuitive correction by a big movement can be performed.

  According to a seventh display method of the present invention, in the display method including a position input step, an input correction step of canceling the position input and inputting a position around the position is included.

  This makes it possible to quickly and easily correct an erroneous input by a peripheral key or the like.

  In the present invention, “pressing” means maintaining the contact state at approximately the same position, for example, for about 0.5 seconds or more, and “pressing” means releasing the contact state in, for example, less than about 0.5 seconds. ".

Further, in the present invention, “slide” means a series of actions in which an operating body such as a finger is moved to another place while being in contact with the touch panel and then released.

According to the present invention, it is possible to provide a display device that can quickly and easily correct a desired input when an erroneous input is made.

Explanatory drawing of the modification of the input correction in the display apparatus as described in Example 1-3 of this invention

  FIG. 1 is a functional block diagram of a display device 100 to which the present invention is applied. A front panel of the display device 100 is provided with a touch panel 105 as display means and position input means. Input by touching the touch panel 105 is detected by the touch detection unit 110 and sent to the central control unit 115 as main processing means and input correction means. A result of the process in the central control unit 115 is displayed on the touch panel 105 through the display control unit 120.

  FIG. 2 is a schematic diagram when the display device 100 is in the alphanumeric input mode. The display on the touch panel 105 is divided into a character display area 200 and a soft keyboard 205. In the character display area 200, an input character 210 as a result of input and a cursor 215 indicating the current input position are displayed. The soft keyboard 205 includes an alphabet key 220 for inputting an alphabet (220a to 220z, the end of the code coincides with the alphabet of the key), and a delete key 225 for deleting the character immediately before the cursor. Note that the delete key 225 is placed away from the outer periphery of the display area of the touch panel 105 to the extent that a slide operation can be performed.

  In addition, although not used in the following description, a shift key 230 for switching between uppercase and lowercase letters, an input switching key 231 for switching to a numeric / symbol input mode, a space key 232 for inputting a space, an enter key for performing a line feed There are also 233.

  In this display device, for example, if alphabet keys 220t, 220e, 220s, and 220t are sequentially pressed, “test” and the input character 210 are displayed in the character display area 200 as a result of inputting these positions.

Moreover, the movement of the cursor may be realized by pressing the input character 210 at the position to be moved, or a key for moving the cursor may be provided separately.
(Example 1-1)
Next, a method of correcting an erroneous character to a desired character when a key adjacent to the desired key is accidentally pressed will be described with reference to the explanatory diagram of FIG. 3 and the flowchart of FIG.

  FIG. 3A shows a state in which “test” is intended to be input, but the alphabet key 220 t is mistaken for the fourth character and the adjacent alphabet key 220 r is pressed. Here, when the delete key 225 is pressed (step S405), as shown in FIG. 3B, the correction loupe 305 is displayed centering on the delete key 225, and further displayed in a gray circle at the center of the correction loupe 305. The corrected pointer 310 is displayed (step S410). Inside the correction loupe 305, around the alphabet key 220 r for inputting “r”, which is the character immediately before the cursor 215 (hereinafter referred to as “correction target character 315”) with the delete key 225 as the center. The correction keys (320e, 320d, 320f, 320t) corresponding to the alphabet keys (220e, 220d, 220f, 220t) are displayed in the same manner as the positional relationship with respect to the alphabet key 220r. Specifically, inside the correction loupe 305, a correction key 320e is displayed on the left side, a correction key 320d is displayed on the lower left side, a correction key 320f is displayed on the lower right side, and a correction key 320t is displayed on the right side.

  Then, as shown in FIG. 3C, when the finger being pressed is slid toward the correction key 320t (step S415), the correction pointer 310 also moves to the position of the correction key 320t according to the movement of the slide. As shown in FIG. 3D, “r” of the correction target character 315 is replaced with “t” (step S420), and “test” can be correctly input.

  In the above description, the case where the cursor 215 is at the end of the input character string has been described. However, when the cursor 215 is in the middle of the character string, the previous character becomes the correction target character 315. Therefore, for example, when the third character “s” is a correction target character, the characters of the correction key 320 in the correction loupe 305 are “a”, “z”, “x”, “d”, “e” counterclockwise from the left. “W”.

  In step S415, if the finger is released when the correction pointer 310 is on the delete key 225 (step S430), only the correction target character 315 is deleted, and no substitute character is input (step S435). If the finger is released when the correction pointer 310 is at a place other than the delete key 225 or the correction key 320 (when the finger is outside the correction loupe 305) (step S440), the correction is canceled and the deletion is also performed. Character input is not performed (step S445).

  In the above description, the correction loupe 305 appears and the correction operation is performed by pressing the delete key 225, that is, for example, by keeping it in contact for about 0.5 seconds, but without waiting for the correction loupe 305 to appear. Alternatively, the deletion key 225 may be quickly slid (flicked) in the direction of the key to be corrected so that the correction can be performed quickly.

  Further, in the present embodiment 1-1, as the surrounding alphabet key 220, the key adjacent to the alphabet key of the character of the correction target character 315 (in a position separated by one) has been described, but a sufficient display area is provided. In some cases, alphabets that are two or more apart (if the correction target character 315 is “r”, “w”, “s”, “x”, “c”, “v”, “g”, “y”) The correction keys 320w to 320y may be displayed outside the correction keys 320 of adjacent characters in the correction loupe 305. In this case, the character can be corrected by sliding the finger to the outer correction keys 320w to 320y.

  Here, the correction loupe 305 is displayed so as to overlap with the deletion key 225 as the center, but may be displayed at a position away from the deletion key 225 in order to prevent the display from being hidden by a finger. . In this case, the distance and direction of movement of the finger from the delete key 225 become the distance and direction of movement of the correction pointer 310.

Furthermore, the correction operation can be performed again using a newly input character as a correction target character. As a result, when an incorrect character is corrected, or when a key at a location two or more minutes away is accidentally pressed, it can be corrected to a desired character by performing a sequential correction operation.
(Example 1-2)
Next, as another embodiment of the above embodiment, a method that does not use the delete key 225 will be described with reference to the explanatory diagram of FIG. 5 and the flowchart of FIG.

  FIG. 5A shows a state where “test” is intended to be input, as in FIG. 3A, but the fourth character is mistaken for the alphabet key 220t and the adjacent alphabet key 220r is pressed. At this time, if the alphabet key 220r corresponding to the correction target character 315 “r” is pressed before the other keys are pressed (step S605), the surrounding alphabet keys ( 220e, 220d, 220f, 220t) changes in color (step S610). Here, when the finger is slid toward the alphabet key 220t (step S615), as shown in FIG. 5C, “r” of the correction target character 315 is replaced with “t” (step S620), and “test” is correctly set. Can be entered.

  According to this method, since it is not necessary to move the finger to the position of the delete key 225, the correction operation can be performed more quickly.

  In step S615, when the finger is released on the alphabet key 220r as it is (step S630), “r” is continuously input as usual (step S640). If the finger is released outside the alphabet key 220 (for example, the character display area 200) (step S645), neither input nor deletion is performed (step S650).

  As in the case of Example 1-1, the correction operation can be performed quickly by quickly sliding (flicking) the alphabet key 220r in the direction of the key to be corrected without waiting for the color of the surrounding alphabet keys to change. It may be.

  The reason why the color of the surrounding alphabet keys 220 is changed in step S610 is to make it easy to understand the characters that can be corrected. Therefore, the pattern and size are changed so that they can be distinguished from other keys. Alternatively, it may be configured not to be changed by a user setting or the like.

  Further, in the present embodiment 1-2, the keys that can be input at the time of correction are adjacent keys (one key apart), but two or more keys are also treated as surrounding keys and slid to that key. By doing so, the character may be corrected.

  Further, instead of changing the color of the surrounding alphabet key 220, the correction loupe 305 as in the embodiment 1-1 may be displayed on the alphabet key 220 to be corrected or at a remote position. In this case, the alphabet key 220 (220r in the above example) of the character to be corrected corresponds to the delete key 225 of Example 1-1, but is deleted when the finger is released on the alphabet key 220r. This is different from Example 1-1 in that the character ("r") is re-input instead of.

In addition, when the cursor 215 is not in the end of the character string but in the middle of the character string, the character immediately before the cursor 215 becomes the correction target character 315 as in the case of Example 1-1. Therefore, even if another key is pressed after making an incorrect input, the display location of the result of the incorrect input (that is, where “r” is displayed in the character display area 200 in the above example). If there is a cursor 215 immediately after, the same correction as described above can be performed by sliding the alphabet key 220r.
(Example 1-3)
In Examples 1-1 and 1-2, in order to correct a character other than the character immediately before the position of the cursor 215, it is necessary to perform a slide operation after the cursor 215 is moved to one character after the character to be corrected. There is. Next, a method for correcting characters other than the previous character at once will be described with reference to the explanatory diagram of FIG. 7 and the flowchart of FIG.

  FIG. 7A shows a state in which “test” is intended to be input but the second character is mistaken for the alphabet key 220e and the adjacent alphabet key 220d is pressed.

  When the input character 210d to be corrected displayed in the character display area 200 is pressed (step S805), the cursor 215 moves immediately after the input character 210d as shown in FIG. Is the correction target character 315. Then, the correction loupe 305 is displayed at a position slightly away so as not to hide the surrounding character string, and the correction pointer 310 represented by a gray circle is displayed at the center of the correction loupe 305 (step S810).

  Inside the correction loupe 305, alphabet keys (220s, 220x, 220x, 220x, around the alphabet key 220d corresponding to the pressed character centered on the enlarged correction target character 710d obtained by enlarging “d” of the correction target character 315. 220c, 220f, 220r, 220e) corresponding to the correction key (320s, 320x, 320c, 320f, 320r, 320e) is displayed in the same manner as the positional relationship with the alphabet key 220d. Specifically, the correction key 320s on the left side, the correction key 320x on the lower left side, the correction key 320c on the lower right side, the correction key 320f on the right side, the correction key 320r on the upper right side, the correction key 320e on the upper left side, and the correction loupe 305 Is displayed on the inside.

  Here, as shown in FIG. 7 (C), slide the finger you are pressing to the upper left side where “e” you want to correct is displayed (for example, the radius of the correction loupe 305 or more in 0.5 seconds). Then, the correction pointer 310 is also moved on the correction key 320e accordingly (step S815), and “d” of the input character 210d is replaced with “e” as shown in FIG. 7D (step S820). , “Test” can be correctly input. After this operation, the cursor 215 returns to the position in the state before step S805 (in FIG. 7A).

  On the other hand, when the finger being pressed is moved little by little (for example, less than the radius of the correction loupe 305 in 0.5 seconds) in step S815 (step S825), immediately after the input character 210 adjacent in that direction. The cursor moves (in this example, for example, if the cursor 215 is moved little by little to the left, the cursor 215 moves immediately after the first input character 210t). Then, the input character 210t, which is the previous character, becomes a correction target character (step S830), and correction is performed with “t” as the center and “r”, “f”, “g”, and “y” as the correction key 320. A loupe 305 is displayed. Therefore, even when the place pressed by the finger deviates from the input character that is desired to be corrected, the input characters 210 that are sequentially adjacent to each other can be made the correction target character 315 by the above operation.

  If the finger is not slid and separated from the center of the correction loupe 305 (step S835), the correction loupe 305 is deleted and the cursor 215 remains at the position (in this example, immediately after the input character 210d). (Step S840).

  The method according to the first to third embodiments is particularly effective when correcting a character other than the one immediately before the cursor 215. However, this method does not prevent correction of a character already in front of the cursor 215 by this method. Absent.

  Further, in the first to third embodiments, the surrounding alphabet keys 220 are described as keys adjacent to the alphabet keys of the correction target characters 315 (one apart), but a sufficient display area is provided. In some cases, alphabets separated by two or more (when the correction target character 315 is “d”, “w”, “a”, “z”, “v”, “g”, “t”) are also treated as surrounding alphabet keys, The correction keys 320w to 320t may be displayed outside the correction keys 320 of adjacent characters in the correction loupe 305. In this case, if the finger is slid to the outside correction key 320 at once, the character can be corrected.

  As described above, the case of alphabet input has been described in the embodiments 1-1 to 1-3, but the present invention can also be applied to a so-called Roman character input mode in which Japanese is input by alphabet. In this case, for example, “t · e · s · u · t · o” is mistakenly entered as “t · e · s · u · t · o” and “te If “i” is displayed, “i” is set as the correction target character 315 by any of the methods of the embodiments 1-1 to 1-3, and the key is corrected to “o” adjacent to the key. Then, the third character “Chi” is replaced with “To”, and “Tetsuto” can be entered correctly. Similarly, if “t · e · s · u · t · p” is entered and “Tes tp” is displayed, “p” is corrected to “o” and “Tesuto” is displayed. You can input correctly.

In addition to the above, it is also possible to apply, for example, a kana input in which 50 sounds are arranged.

  FIG. 9 is a schematic diagram when the display device 100 is in the kana input mode. The display on the touch panel 105 is divided into a character display area 200 and a soft keyboard 205. In the character display area 200, an input character 210, a cursor 215 indicating the current input position, and an unconfirmed underline 905 indicating that the input character is unconfirmed are displayed. On the soft keyboard 205, a kana key 910 for inputting hiragana ("a" is 910a, "ka" is 910k,. ), Adding a dakuten / semi-dakuten or making a character small (for example, “T” is changed to “Z” or “T”), a related character key 915, a punctuation key 920 for inputting a punctuation mark, and a character is deleted. There is a delete key 925 and a character conversion key 930 for performing character conversion. Note that the delete key 925 is placed away from the outer periphery of the display area of the touch panel 105 to the extent that a slide operation can be performed as in the first embodiment.

  In addition, although not used in the following explanation, in addition, it returns to the previous sound (for example, when “to” is input, it changes to “te” “tsu” “chi” “ta” each time it is pressed). Back key 935, left move key 936 for returning the cursor one character forward, symbol input mode key 937 for entering symbol input mode, alphanumeric input mode key 938 for entering alphanumeric input mode, right move key for moving the cursor forward one character There is also an enter key 940 for confirming a character string and performing a line feed.

  Each kana key 910a-w is assigned i-sound, u-sound, e-sound, and o-sound in order of left, top, right, and bottom. Therefore, for example, when inputting “test” in the character display area 200, the kana key 910t is slid to the right, the 910s is slid upward, and the 910t is slid downward. ”And“ test ”may be selected from the conversion candidates that appear when the character conversion key 930 is pressed. If you want to input a letter whose consonant is a (a, ka, sa, ta, ...), just press it without sliding. In addition, related characters are also assigned to the related character key 915 and the punctuation mark key 920 in each direction.

It should be noted that by pressing each kana key 910, an input loupe 1005 as shown in FIG. 10A can appear, and a slide operation can be performed with reference thereto.
(Example 2-1)
Next, a method of correcting an erroneous character to a desired character when it is accidentally slid in a different direction from the desired character will be described with reference to the explanatory diagram of FIG. In addition, although the display content of this Example 2-1 is different from Example 1-1, since the flow of operation is the same as that of Example 1-1, the flowchart was used for description in Example 1-1. FIG. 4 is used. In the flowchart of FIG. 4, “correction loupe” corresponds to “kana correction loupe”, and “correction key” corresponds to “kana correction key”.

  In FIG. 10 (A), “Tesuto” is intended to be entered, but the third character is mistaken for sliding down the kana key 910t to the right and sliding to the right. "Is the state when" "has been entered. If the delete key 925 is pressed (step S405), a kana correction loupe 1015 is displayed centering on the delete key 925 as shown in FIG. 10B (step S410). Inside the kana correction loupe 1015, with the deletion key 925 as the center, the correction target character 315 (“te”) is excluded from the row of the kana key 910 t to which the correction target character 315 (“te”) belongs. A character kana correction key 1020 (“Ta” is 1020 ta, “Chi” is 1020 ti, “T” is 1020 tu, “To” is 1020 to) is displayed vertically and horizontally, and a correction pointer 310 is displayed at the center of the kana correction loupe 1015. Is displayed.

  Note that the arrangement order of the kana correction keys 1020 is different from that of the input loupe 1005, and the sound of “a line” (in this example “t” in the place where the character 315 to be corrected (“te” in this example) is located in the input loupe 1005. ") Is coming. That is, in this example, a kana correction key 1020ti on the left side, a kana correction key 1020tu on the upper side, a kana correction key 1020ta on the right side, and a kana correction key 1020to on the lower side inside the kana correction loupe 1015 are displayed. However, when the correction target character 315 is “A”, the positional relationship between the characters of the input loupe 1005 and the kana correction loupe 1015 is the same.

  Then, as shown in FIG. 10C, when the finger is slid onto the lower kana correction key 1020to (step S415), the correction pointer 310 is also moved onto the kana correction key 1020to according to the movement of the slide. As shown in FIG. 10D, the entered characters “te” are replaced with “to” (step S420), and “tetsuto” can be correctly entered.

  In the above description, the case where the cursor 215 is at the end of the input character string has been described. However, when the cursor 215 is in the middle of the character string, the character immediately before that becomes the correction target character 315. Therefore, for example, if the second character “SU” is the character to be corrected, the characters of the Kana correction key 1020 in the Kana correction loupe 1015 are “SHI” “SA” “SE” “SO” clockwise from the left. Become.

  In step S415, if the finger is removed when the correction pointer 310 is on the delete key 925 (step S430), only the correction target character 315 is deleted, and no substitute character is input (step S435). If the finger is released when the correction pointer 310 is at a place other than the delete key 925 or the kana correction key 1020 (step S440), the deletion is canceled and neither deletion nor character input is performed (step S445).

  Further, in the above description, the kana correction loupe 1015 appears and the correction operation is performed by pressing the delete key 925, that is, by keeping the contact for about 0.5 seconds, for example, but the kana correction loupe 1015 appears. It is also possible to perform quick correction by quickly sliding (flicking) the delete key 925 in the direction of the key to be corrected without waiting.

  Here, the kana correction loupe 1015 is displayed so as to overlap with the delete key 925 as the center, but it may be displayed at a position away from the delete key 925 in order to prevent the display from being hidden by a finger. good. In this case, the moving distance and moving direction of the finger from the delete key 925 become the moving distance and moving direction of the correction pointer 310.

  Furthermore, the correction operation can be performed again using a newly input character as a correction target character. Thereby, when it corrects to the wrong character, it can correct to a desired character by performing correction operation | movement sequentially.

  Further, in the present embodiment 2-1, the case where the correction is performed immediately after the kana key 910 is pressed has been described. It can be corrected to a dakuten character. Similarly, when the punctuation mark key 920 was pressed immediately before, it becomes possible to correct the punctuation mark to a punctuation mark, for example.

  As a modification of Example 2-1, a method of correcting not only characters on the same line but also characters on adjacent lines will be described.

  As shown in FIG. 11A, four kana correction keys 1020 of “Ta line” are arranged in the kana correction loupe 1015 in an oblique direction rather than up, down, left, and right. Therefore, when a finger is slid in an oblique direction, the character is corrected to that direction. On the other hand, when the finger is moved little by little in the up / down / left / right direction, the contents of the kana correction loupe 1015 can be changed to a line adjacent to the kana key in that direction.

  For example, when the finger is moved gradually upward as shown in FIG. 11B, the characters (a, i, u, kana key 910a (a line) above the kana key 910t (ta line) in FIG. E) is displayed in the kana correction loupe 1015 as the kana correction key 1020 as shown in FIG. In FIG. 11C, the kana correction keys 1020 are arranged in the order of a sound, i sound, u sound, e sound, and o sound in the order of center, lower left, upper left, upper right, and lower right. Then, as shown in FIG. 11D, when the finger is slid toward “U” in the upper left, “U” is input instead of the correction target character.

In the above example, the kana correction key 1020 in the kana correction loupe 1015 has been described as being diagonally arranged. In this case, however, in order to avoid confusion, the characters in the input loupe 1005 may be also diagonally arranged. desirable.
(Example 2-2)
Next, as a further application of the above-described embodiment, a method for correcting input characters other than the one immediately before the cursor 215 at once will be described with reference to FIG. In addition, although the display content of this embodiment 2-2 is different from that of the embodiment 1-3, the flow of operation is the same as that of the embodiment 1-3. Therefore, the flowchart is used for the description of the embodiment 1-3. FIG. 8 is used. In the flowchart of FIG. 8, “correction loupe” corresponds to “kana correction loupe”, and “correction key” corresponds to “kana correction key”.

  In FIG. 12A, although “Tesuto” is intended to be input, the first character is mistaken to slide the kana key 910t to the right and is slid upward. This is the state when is entered. If the input character 210tu (“tsu”) displayed in the character display area 200 is pressed (step S805), a kana correction loupe 1015 is displayed as shown in FIG. The correction pointer 310 is displayed at the center of 1015 (step S810).

  Inside the kana correction loupe 1015, an enlarged correction target character 1105tu obtained by enlarging the “correction target character 315” is centered on the kana key 910t (ta line) of the line to which the correction target character 315 (“t”) belongs. Corresponding kana correction keys (1020ta, 1020ti, 1020te, 1020to) are displayed vertically and horizontally. It should be noted that the arrangement order of the kana correction keys 1020 is the same as in the embodiment 2-1, so that the sound of "A line" comes to the place where the character to be corrected ("tsu" in this example) is present in the input loupe 1005. It has become.

  Here, as shown in FIG. 12 (C), the finger that is pressed is slid rightward (for example, by half or more of one side of the kana correction loupe 1015 in 0.5 seconds) to the right with the character “te” to be corrected. Then, the correction pointer 310 is also moved over the kana correction key 1020te accordingly (step S815), and as shown in FIG. 12D, the character “315” of the correction target character 315 is replaced with “te” (step S820). , "Tesuto" can be entered correctly.

  In step S815, when the finger being pressed is moved little by little (for example, less than half of one side of the kana correction loupe 1015 in 0.5 seconds) (step S825), the input character 210 adjacent in the direction is moved. The cursor moves immediately after (in this example, when the cursor 215 is moved little by little to the right, the cursor 215 moves immediately after the input character 210su). The previous character becomes the correction target character 315 (step S830), and a new kana correction loupe is displayed. Therefore, even when the place pressed by the finger deviates from the character to be corrected, the input characters that are sequentially adjacent by the above operation can be set as the correction target characters.

  If the finger is released at the center of the kana correction loupe 1015 (step S835), the kana correction loupe 1015 is erased and the cursor 215 remains at the same position (in this example, immediately after the input character 210tu) ( Step S840).

  If the correction target character 315 has a related character (for example, “tsu”, “zu” or “tsu”), the related character may be added to the kana correction key 1020.

  If priority is given to the ease of understanding, instead of the kana correction loupe 1015 of the second embodiment, the kana correction key 1020 is moved clockwise from the left as shown in FIGS. 13 (A) and 13 (B). You may use the order of u, e, o sound (however, excluding the enlargement correction target character 1105).

  As yet another method, as shown in FIGS. 14A to 14D, a kana correction key 1020 arranged vertically or horizontally may be used as a correction loupe. In this case, the kana correction key 1020 to be used for correction may be determined according to the size of the slide distance, or the slide for each character may be corrected repeatedly.

  Further, in the second embodiment, the slide input at the time of inputting the kana has been described, but the same correction can be performed even when the alphanumeric input is performed by the slide.

The embodiments 2-1 and 2-2 can also be applied to an input method in which characters are changed like “ta”, “chi”, “tsu”,... By pressing the kana key a plurality of times. . In this case, the characters in the same line are not corrected, but the characters of the same consonant (“O”, “NO”, “MO” in the case of “to”) in the adjacent row of the kana key 910 are corrected to kana. It may be displayed on the loupe 1015.
(Example 2-3)
Next, input correction when the predictive conversion function is used will be described with reference to FIG. In addition, since it is the same operation | movement as Example 2-1 and 2-2 except the part in connection with prediction conversion, description is abbreviate | omitted about a common part.

  FIG. 15A shows a state in which a list of conversion candidate keys 1050 is displayed at the bottom of the character display area 200 by predicting a character string that is highly likely to be converted when “Aka” is input. is there. Here, if the conversion candidate key 1050b of “bright” is mistaken and the adjacent conversion candidate key 1050b of “baby” is pressed, a character string “baby” is input as shown in FIG.

  Here, when the delete key 925 is pressed, a conversion candidate correction loupe 1055 is displayed as shown in FIG. 15C, and the conversion candidate key 1050 around the conversion candidate key 1050b of “baby” in FIG. 15A is displayed. Is displayed in the conversion candidate correction loupe 1055 while maintaining the same vertical and horizontal positional relationship.

  Then, by sliding the finger to the left side, as shown in FIG. 15D, the “baby” of the input character 210 is replaced with the character string “brightly” on the left side of the conversion candidate correction loupe 1055.

Note that when the delete key 925 is pressed without sliding, the character immediately before the cursor 215 (here, “n”) is deleted. However, the present invention is not limited to this, and a character string (here, which is input by predictive conversion). “Baby”) may be deleted at once.

  FIG. 16A is a schematic diagram when the display device 100 is in the web browsing mode. The display on the touch panel 105 is divided into a web screen area 1205 and a tool button area 1210. In the web screen area 1205, a link 1215 (1215a to 1215m, the end of the code is in alphabetical order from the top) that can be moved to a designated web page by pressing is displayed. In the tool button area 1210, a return key 1220 for performing an operation of returning to the previously browsed web page, a menu key 1225 for displaying various menus, and a return key 1220 for returning to the previous page. There is a forward key 1230 for displaying the previous page again.

  Next, when a link adjacent to a desired link is accidentally pressed, a method for correcting the wrong linked web page to the desired linked web page is described with reference to the explanatory diagram of FIG. 16 and the flowchart of FIG. It explains using.

  FIG. 16A shows a state in which the “news” link 1215d is intended to be pressed on the top page 1235, but the “weather” link 1215e below is erroneously pressed. When the link 1215e is pressed, a dotted frame indicating that the link 1215e has been selected is displayed around the link 1215e. Thereafter, the link 1215e is moved to a linked weather page 1236 as shown in FIG.

  Here, as shown in FIG. 16C, when the return key 1220 is pressed (step S1305), a link correction loupe 1240 is displayed (step S1310). Inside the link correction loupe 1240, the peripheral portion of the link 1215e in the top page 1235, which is the previous page, is reproduced. Specifically, a correction link 1215d connected to the news page 1237 is displayed above the correction link 1215e connected to the weather page 1236. Further, the correction pointer 310 is displayed so as to overlap the correction link 1215e.

  Here, as shown in FIG. 16D, when the finger is slid upward (step S1315), the correction pointer 310 is also moved accordingly, and the dotted frame indicating that it is selected is the correction link. It is displayed around 1215d, and can move from the weather page 1236 to the news page 1237 at a stretch as shown in FIG. 16E (step S1320).

  In step S1315, if the finger is released without being slid (step S1330), the process returns to the previous top page 1235 as usual (step S1335). If the finger is released when the correction pointer 310 is located at a place other than the correction link 1215 (step S1340), the return function is canceled and the weather page 1236 remains unchanged (step S1345).

  By the way, in order to display a part of the previous page in the link correction loupe 1240 in step S1315, it is necessary to retain and redisplay the information of the previous page. If this is difficult, only data representing the page structure (HTML, CSS, etc.) may be held, and the positions of surrounding links may be estimated from the data and displayed.

  In the present embodiment, the correction method is described by pressing the return key 1220 and then sliding it. However, the return key 1220 is quickly slid in the direction of the link to be corrected to wait for the appearance of the link correction loupe 1240. Alternatively, the correction operation may be performed.

  In addition, when it is noticed that the page has been accidentally pushed before the destination page is displayed, the vicinity of the place of the link that was mistakenly pushed is pressed again in the same manner as in the embodiment 1-2. Accordingly, the correction operation may be performed by displaying the link correction loupe 1240 around it so that the correction operation by the slide can be performed, or by flicking the vicinity of the place where it is accidentally pressed.

  In addition, after the appearance of the link correction loupe 1240, the finger that has been pressed is slid to a link that is two or more away (in the above example, the “travel” link 1215c, etc.), so that the user can proceed to the travel page. good.

  In this embodiment, the correction operation when an adjacent link is erroneously selected has been described. However, for example, when the user wants to view the news page 1237 after viewing the weather page 1236, the correction operation is not necessary. The time required for browsing the page can be shortened. In this case as well, it is included in the concept of “cancel” and “correction” in the sense that the current page becomes unnecessary and a new page is requested.

  Furthermore, it is not limited to input correction in a web browser, but can be applied to various software operations where keys and icons are arranged as long as the system has a key for deleting and a key for returning to the previous screen. can do.

  As described above, in the first to third embodiments, the erroneous operation correction by the touch operation has been described. However, the application range is not limited to the present embodiment as long as the positional input deviation is corrected quickly. For example, when inputting by clicking a button with a mouse, the same correction can be performed by replacing the slide operation of this embodiment with, for example, a drag operation while pressing the right click. In addition, even in the case of a pointing device that moves by reading the direction and movement of the main body and performs a determination operation with a button, the sliding operation of this embodiment is replaced with an operation for moving the main body while holding down the button, for example. A similar correction can be made.

  Further, instead of designating a direction by touch slide, an acceleration sensor as a motion detecting means may be provided, and the display device may be corrected in the direction by tilting the display device up, down, left, or right. Specifically, as shown in FIG. 18, by tilting the entire display device to the right and returning it, “r” can be corrected to “t” on the right side. In this case, there is an advantage that correction can be performed with a large operation without pressing a small terminal with a finger.

  Further, not only two-dimensional input / correction but also three-dimensional input / correction including depth may be performed. At this time, the “slide operation” in the three-dimensional space may be, for example, an operation of lifting a mouse that can recognize a three-dimensional input while right-clicking.

  In addition, a camera system that captures and recognizes the user's face may be provided, and the user may correct the direction by shaking the face. Even in this case, correction can be performed without pressing a small terminal with a finger. That is, the present invention can be applied not only to the above-described embodiment as long as it has means for inputting a direction.

Further, the present invention can be applied not only to the input of the position in the space but also to the input by voice, for example, by setting the pitch of the sound as the input of the position on the score. As a specific example, when a melody is sung and input, if one sound shifts to the higher side, it is corrected to a lower sound by speaking "correction" immediately with a lower sound. I think that.

According to the present invention, it is possible to provide a display device that can quickly and easily correct a desired input when an erroneous input is made.
