Description

  The present invention relates to a character input device, method, and program, and more particularly, to a character input device, method, and program using a virtual keyboard displayed on a touch panel in a PDA (personal portable information communication device).

  PDAs that have become popular in recent years have been reduced in size with an emphasis on portability, so the input portion has become smaller. For this reason, the character input method using a virtual keyboard that displays a list of all the characters that have been used in the past and selects the necessary characters from the list displays the characters that you are trying to input because the input area is small. There is a problem that it is difficult to select correctly.

  In order to eliminate the difficulty of character input due to such a small input part, a part of the virtual keyboard was enlarged and displayed by clicking the part with the tap position aligned with it. There was a method of pointing the input character by clicking the key again after aligning the tap position.

  Next, with reference to the flowcharts of FIGS. 1 to 8 and FIG. 11, the entire operation from when the user taps the key “hi” on the virtual keyboard 20 until “pi” is determined as the input character will be described in detail. .

  As shown in FIG. 5, when the user taps the position of the key “hi” on the virtual keyboard 20 displayed on the touch panel 10, an event occurs in the tap event generation unit 110, and the tapped coordinates (55, 15) are displayed. Is output (step F100 in FIG. 11).

  Next, the input coordinate detection processing unit 210 acquires the tapped coordinates (55, 15) from the operating system (step F110).

  Next, in order to detect the target key to be enlarged and displayed, the enlarged key detection processing unit 220 determines that the distance between the coordinates of each key stored in the virtual keyboard coordinate information table T10 and the tapped coordinates is 20 in this embodiment. The following keys are extracted (step F120). An adjacent key range 13 is within a circle having a radius of 20 from the center of the key “HI”. In addition, about the distance from the tapped coordinate which specifies the key to expand, 20 is an example and it changes with an apparatus, a specification, a use, etc.

  When the distance from the coordinate of the tapped key “hi” to the coordinate of each key is calculated, the result shown in FIG. 6 is obtained, and a key having a distance of 20 or less is used as an adjacent key to be enlarged. “NA”, “NI”, “NU”, “HA”, “HI”, “FU”, “HE”, “MA”, “MI”, “MU”, and “DE” are recorded as adjacent keys to be enlarged.

  Next, the tentatively confirmed character detection processing unit 230 sets the tapped coordinate (55, 15) and the key “hi” present at the shortest position as the target key to be enlarged, and the character “hi” as the tentatively confirmed character. Record (step F130).

  Next, the auxiliary input information acquisition unit 240 searches for data in which the key item of the auxiliary input information table T20 is “hi”, and the item of presence / absence of auxiliary candidate characters is “◯”, so that candidate 1, candidate 2, The auxiliary candidate characters “pi”, “bi”, “byu”, and “byo” are acquired from the items of candidates 3 and 4 (steps F140, F150, and F160).

  The key “” of the virtual keyboard 20 is similar to the auxiliary enlarged key 19 indicating the auxiliary candidate characters “pi”, “bi”, “byu”, and “byo” arranged in the enlarged key 18 in the enlarged image 12 of FIG. When the key “hi” is divided by placing it in “hi”, the tapped coordinates (55, 15) are the auxiliary candidate characters “hi” “pi” “bi” “byu” “byo” in the key “hi”. ”Is checked to determine which character is present in the divided area. In the case of FIG. 5, since the tapped coordinate is located not in the area corresponding to any auxiliary candidate character at the center of the key “hi” but in the central area of the key indicating the character “hi”, Is determined to be “hi” (step F170).

  Next, the enlarged display processing unit 250 displays the enlarged image 13 as shown in FIG.

  The magnified image 12 displays the magnified key 18 whose side is a distance 50 enlarged by 5 times the key “HI” as the target key in step 130, and the supplementary magnified key indicating the supplementary candidate character at the periphery of the magnified key 18. 19 is displayed according to the arrangement specified by the items of candidates 1 to 4 in the auxiliary input information table T20. That is, the auxiliary enlarged key 19 indicating the auxiliary candidate character “pi” is arranged on the left side edge of the enlarged key 18, the auxiliary enlarged key 19 showing the auxiliary candidate character “bi” is arranged on the right side edge, and the upper side The auxiliary enlarged key 19 indicating the auxiliary candidate character “Byu” is arranged at the edge, and the auxiliary enlarged key 19 indicating the auxiliary candidate character “Byo” is arranged and displayed at the lower edge. In this case, the central portion of the enlargement key 18 excluding the portion where the auxiliary enlargement key 19 is arranged is a key indicating the character “hi” in the enlarged image 12.

  Note that the arrangement of the auxiliary enlargement key 19 in the enlargement key 18 will be described in detail using a specific example. The enlargement key 18 is a square with a distance of 50 and one side arranged in the center of the enlargement key 18 is a square with a distance of 30. Is a key indicating "hi", and the left and right and upper and lower parts obtained by dividing the square-shaped part surrounded by both squares into a square diagonal line having an outer shape of four are divided into auxiliary candidate characters "pi" and " It is assumed that the auxiliary enlargement key 19 indicates "Bi", "Byu", and "Byo". In addition, what is necessary is just to select an appropriate value for the distance which determines the arrangement | positioning of such an auxiliary | assistant expansion key 19 with an apparatus, a specification, a use, etc. Further, when determining a provisionally confirmed character in step 170, there is a problem that the position of the tap is located at the boundary of the area similar to the auxiliary enlarged key 19 of the key of the virtual keyboard 20, but the auxiliary enlarged key 19 is enlarged. A priority order that prioritizes the key 18 and prioritizes the left and right auxiliary enlargement keys 19 over the upper and lower auxiliary enlargement keys 19 may be set. However, the present invention is not limited to this, and other appropriate methods may be used.

  Further, the adjacent enlarged key 21 indicating the characters “mi” and “” ”of the adjacent key on the left side of the key“ HI ”is arranged in accordance with the arrangement of the virtual keyboard 20 on the right side of the enlarged key 18, and the character“ NI ”of the adjacent key on the right side. An adjacent enlarged key 21 indicating “Chi” is arranged on the left side of the enlarged key 18 in accordance with the virtual keyboard 20, and an adjacent enlarged key 21 indicating the character “ha” of the adjacent key above the key “HI” is placed above the enlarged key 18. Arranged according to the virtual keyboard 20, the adjacent enlarged key 21 indicating the characters “fu” and “to” of the lower adjacent key is arranged below the enlarged key 18 according to the virtual keyboard 20. Furthermore, the character “MA” of the upper left adjacent key of the key “HI” of the virtual keyboard 20, the character “MU” of the lower left adjacent key, the character “NA” of the upper right adjacent key, and the lower right upper right key. The adjacent enlargement keys indicating the characters “N” of the adjacent keys are arranged on the upper left, the lower left, the upper right, and the lower right of the enlargement key 18 according to the arrangement of the virtual keyboard 20.

  Explaining a specific example, the adjacent enlargement key 21 indicating the characters “mi”, “d”, “ni”, and “chi” of the adjacent key is a rectangle having a distance of 50 in the vertical direction and a distance of 10 in the horizontal direction. The adjacent enlargement key 21 indicating "" "" is a rectangle having a distance of 10 in the vertical direction and a distance of 50, and the adjacent enlargement key 21 indicating the characters "ma", "mu", "na", and "nu" has a distance of 10 in both vertical and horizontal directions. As a square.

  At this time, the background color of the candidate keys (the center portion of the enlarged key 18 indicating the character “HI” and the auxiliary enlarged key) excluding the key indicating the temporary fixed character is displayed in light red, and the key indicating the temporary fixed character (FIG. In the case of 5, the background color of the enlargement key 18 is displayed in red (step F180). At this point, the display screen 510 is displayed as shown in FIG.

  At this point, “hi” is a temporarily confirmed character. Next, as shown in FIG. 7, the touch panel 10 is kept tapped to input the character “pi”. Move tapped coordinates to the left. Since the tap coordinates are moved while the touch panel 10 is tapped, the input confirmation processing unit 260 returns the processing to the input coordinate detection processing unit 210 without confirming the character input (step F190).

  Since the input is not confirmed, the input character is confirmed again, and the input coordinate detection processing unit 210 acquires the coordinates (58, 15) of the tap after moving to the left from the operating system (step F110).

  Next, the enlarged key detection processing unit 220 detects the key to be enlarged and displayed, so that the distance between the coordinates of each key of the virtual keyboard 20 stored in the virtual keyboard coordinate information table T10 and the tapped coordinates is 20. The following keys are extracted (step F120). The calculation result of the distance to the tapped coordinate is as shown in FIG. 8, and since the keys having a distance of 20 or less are the adjacent keys to be enlarged, “NA”, “NI”, “NU”, “HA”, “HA” "H", "F", "MA", "MI", "MU", "YA", "D", and "YU" are recorded as adjacent keys to be enlarged.

  Next, the provisionally confirmed character detection processing unit 230 records the tapped coordinates (58, 15) and “hi” existing at the shortest position as a provisionally confirmed key (step F130).

  Next, the auxiliary input information acquisition unit 240 searches for data in which the key item of the auxiliary input information table T20 is “hi”, and the item of presence / absence of auxiliary candidate characters is “◯”, so that candidate 1, candidate 2, The auxiliary candidate characters “pi”, “bi”, “byu”, and “byo” for the items of candidate 3 and candidate 4 are acquired (steps F140, F150, and F160).

  In the key “hi” of the virtual keyboard 20 to resemble the auxiliary enlarged key 19 indicating the auxiliary candidate characters “pi” “bi” “byu” “byo” arranged in the enlarged key 18 in the enlarged image 14 of FIG. When the key “Hi” is divided into the keys, the tapped coordinates (58,15) are the auxiliary candidate characters “Hi”, “Pi”, “Bi”, “Bu”, and “Byo” in the key “H”. It is checked whether it exists in the divided area corresponding to, and a provisionally confirmed character is determined. In the case of FIG. 7, since the tapped coordinate is located at the edge of the left side of the key “HI” and is located in the area corresponding to the auxiliary candidate character “PI”, the provisionally confirmed character is “PI”. Judgment is made (step F170).

  Next, the enlarged display processing unit 250 displays the enlarged image 14 as shown in FIG. In step 130, the key “HI” as the target key is enlarged five times, the enlarged key 18 having a distance of 50 is displayed, and the auxiliary enlarged key 19 indicating auxiliary candidate characters is displayed on the peripheral portion of the enlarged key 18 in the auxiliary input information table. It displays according to the arrangement | positioning which the item of the candidate 1-4 of T20 designates.

  In addition, the adjacent enlargement key 21 indicating the characters “NA”, “NI”, “NU”, “HA”, “HI”, “FU”, “MA”, “MI”, “MU”, “YA”, “DE”, “YU” is expanded. Arranged around the key 18 according to the arrangement of the virtual keyboard 20.

  At this time, the background color of the candidate keys (the center portion of the enlarged key 18 indicating the character “HI” and the auxiliary enlarged key) excluding the key indicating the temporary fixed character is displayed in light red, and the key indicating the temporary fixed character (FIG. In the case of 7, the background color of the auxiliary enlarged key 19) indicating the auxiliary candidate character “pi” is displayed in red (step F180). At this point, the display screen 510 is displayed as shown in FIG.

  Next, the input confirmation processing unit 260 confirms that the auxiliary enlarged key 19 indicating the auxiliary candidate character “PI” that the user intends to input is displayed in red, and is a provisionally confirmed character. When the touch pen or the like is released from the touch panel to release the tap and click, the input confirmation processing unit 260 determines the character “pi”, which is a provisionally confirmed character, as input confirmation (steps F190 and F200). At the same time, the input confirmation processing unit 260 deletes the enlarged image 14 (step F210).

  Next, with reference to the flowcharts of FIGS. 1 to 4, 9 and 10, and FIG. 8, the entire operation until the character “Mu” is entered is described in detail (in this example, not the center of “Mu” but the right side). Tapping down).

  When the user taps the position of the key “Mu” on the virtual keyboard 20 displayed on the touch panel 10, an event is generated in the tap event generation unit 110, and the tapped coordinates (62, 29) are output (step F100). .

  Next, the input coordinate detection processing unit 210 obtains the coordinates (62, 29) that are not accurately centered on the key “Mu” but are shifted to the lower right from the operating system (step F110).

  Next, in order to detect the key to be enlarged and displayed, the enlarged key detection processing unit 220 determines the distance between the coordinates of each key of the virtual keyboard 20 stored in the virtual keyboard coordinate information table T10 and the tapped coordinates. In the embodiment, 20 or less keys are extracted (step F120). When the distance between the tapped coordinate and the coordinate of each key is calculated, the distance calculation result shown in FIG. 10 is obtained. Since the distance is 20 or less, the keys “Nu” “Ne” “Hi” “Fu” “He”, “ho”, “mi”, “mu”, “me”, “mo”, “”, “yu”, and “°” are recorded as the adjacent keys to be enlarged.

  Next, the provisionally confirmed character detection processing unit 230 records the tapped coordinates (62, 29) and the character “Mu” of the key existing at the shortest position as a provisionally confirmed character (step F130).

  Next, the auxiliary input information acquisition unit 240 searches for data in which the key item of the auxiliary input information table T20 is “Mu”, and the item of presence / absence of auxiliary candidate characters is “x”. The auxiliary enlargement key is not displayed (steps F140 and F150).

  Next, the enlarged display processing unit 250 displays the enlarged image 16 as shown in FIG. In step 130, the enlargement key 18 having a distance of 50 on one side indicating “Mu” as a provisionally confirmed character is displayed.

  Also, the adjacent enlargement key indicating the characters “Nu” “Ne” “Hi” “Fu” “He” “Ho” “Mi” “Mu” “M” “Mo” “B” “Y” “°” 21 is arranged around the enlargement key 18 in accordance with the arrangement of the virtual keyboard 20.

  At this time, the background color of the enlargement key 18, which is a key indicating the temporarily confirmed character “Mu”, is displayed in red (step F180). At this point, the display screen 510 is displayed as shown in FIG.

  Next, the input confirmation processing unit 260 confirms that the enlarged key 19 indicating the character “Mu” to be input by the user is displayed in red and is a provisionally confirmed character, and taps the touch pen or the like away from the touch panel. When the button is canceled and clicked, the input confirmation processing unit 260 determines the character “mu”, which is a provisionally confirmed character, as input confirmation (steps F190 and F200). At the same time, the input confirmation processing unit 260 deletes the enlarged image 16 (step F210).

  The character input device of the present invention facilitates the input of characters such as muddy sounds, etc. In addition, since the target key is enlarged and displayed as an enlarged key by tapping, and the character confirmed by clicking is input, There is no need for two clicks at the time of enlargement and input confirmation, and there is an effect that characters can be input by one click.

  In addition, by displaying the adjacent enlarged key around the expanded key, it is easy to correct the tap position, and only the limited key within a certain distance from the tap position is used as the adjacent key, and the adjacent expanded key is expanded. Enlarging by displaying the area around the key, by reducing the ratio of the size of the adjacent enlarged key to the adjacent key of the corresponding virtual keyboard rather than the enlargement ratio of the size of the enlarged key to the target key of the virtual keyboard There is an effect that the area required for displaying the key and the adjacent key can be minimized.

  Also, always monitor the tap position, and when the tap position moves and the key closest to the tap position changes, the target key is updated immediately, and the characters indicated by the expanded key and adjacent key are also updated accordingly. Thus, it is possible to dynamically change the area of the virtual keyboard that is enlarged and displayed as the enlargement key and the adjacent key in accordance with the movement of the tap position. Therefore, the selection of keys on the virtual keyboard can be performed quickly only by moving the tap.

  Whether to temporarily cancel the tap and click to enter the desired character by displaying the tentatively confirmed character among the enlargement key, auxiliary enlargement key, etc. with specific modification. It is possible to easily determine whether to click after correcting the tap position.

  It should be noted that the characters include various characters and symbols such as “kana” and the like, as well as dakuten, semi-dakuten, punctuation, and parentheses. Further, the virtual keyboard 20 can be switched to display hiragana, kana, English alphabet or numbers by tapping the bottom key.

  Further, as auxiliary candidate characters, various characters and symbols can be included in addition to muddy sounds, semi-voiced sounds, and roaring sounds. For example, when the key of the virtual keyboard represents the capital letter of the alphabet type, the supplementary candidate character can include a small letter or cursive letter.

  In addition, the virtual keyboard 20 shown in FIG. 5 and the like arranges the keys in a grid pattern, but the arrangement of the keys also shifts the arrangement of the keys by a half pitch at the upper and lower adjacent stages like a normal keyboard. Various things may be used. Even in such a case, the adjacent enlargement key 21 is arranged around the enlargement key 18 according to the arrangement of the keyboard.

  Further, the present invention can be implemented without arranging the adjacent enlargement key 21 around the enlargement key 18. Even in this case, it is possible to easily input auxiliary candidate characters.

  Further, the specific modification and the separate specific modification are not limited to the red display and the light red display, but may be a display by another color, a display by a brightness difference, a display by blinking, or the like.

  In addition, indication point marks such as a cursor and an arrow can be displayed at the position on the enlarged key 18 corresponding to the position on the target key of the indication point by the tap on the virtual keyboard 20. In this case, it is possible to easily visually grasp where the virtual keyboard 20 is tapped.

  5 and 7 show a case where the periphery of the enlargement key 18 is divided into four parts in the left and right and up and down directions to display four auxiliary candidate characters, but the key “ha” in the auxiliary input information table T20 in FIG. 4 is displayed. Thus, when there are two auxiliary candidate characters “Pa” and “Ba”, the auxiliary enlargement key 19 is arranged on the left and right of the enlargement key 18, and the left and right portions of the peripheral portion of the target key “ha” of the virtual keyboard 20 are tapped. Then, the corresponding auxiliary candidate character “Pa” or “B” is set as a temporary confirmation character, but if the upper and lower portions are tapped, the character “ha” of the target key is set as a temporary confirmation character. Similarly, when there is one auxiliary candidate character, the auxiliary enlargement key 19 is displayed on the left edge of the enlargement key 18, and when it is 3, the auxiliary enlargement key 19 is displayed on the left and right and upper edges of the enlargement key 18. .

  Further, when there are five or more auxiliary candidate characters, the peripheral edge of the enlargement key 18 can be divided into five or more and the five auxiliary enlargement keys 19 can be displayed. FIG. 12 is an enlarged view of eight auxiliary enlargement keys 19 indicating eight auxiliary candidate characters “pi”, “bi”, “byu”, “byo”, “hyu”, “hyo”, “pyu”, and “pyo” for the character “hi”.
