<Embodiment 1>
The character input receiving method according to the first embodiment of the present invention is a method for receiving character input from a user using a touch panel in a portable information processing terminal having a touch panel such as a smartphone or a tablet terminal. When the user slides the slide bar displayed at the end of the display area of the screen with a finger or the like, a character corresponding to the position is input. In the virtual keyboard, since an area having an area that can be directly designated with a finger or the like is assigned to each of the selectable characters and the like, the occupied area in the display area is increased. Since selectable characters are assigned to the position information of the slide bar, the occupied area in the display area can be significantly reduced.

  FIG. 1 is a diagram showing an outline of an example of a character input receiving method according to the first embodiment of the present invention. 1A to 1E, a portable terminal 1 such as a smartphone has a touch panel 20, which displays a screen and inputs a touch or gesture with a finger from a user. Accept. In the example of FIG. 1, there is an area for displaying characters input at the top of the screen (for example, “rain rain” in the example of FIG. 1A), while at the bottom of the screen, along the lower side of the display area. A slide bar 21 slidable in the direction is displayed. The display position of the slide bar 21 is not limited to this. For example, in the case of a right-handed (or left-handed) user, the slide bar 21 may be displayed so as to be slidable vertically along the right side (or left side). May be displayed so as to be slidable in the horizontal direction. Depending on the requirements of the application etc., it is possible to display other than the edge of the screen.

  In FIG. 1A, when it is detected that the user has touched with a finger to slide the slide bar 21, the initial value of the character in the initial value of the character type (Hiragana in the example of FIG. 1) (five in the example of FIG. 1). The first “a” of the ten-tone arrangement is displayed as a candidate so that it can be selected in the vicinity of the position touched by the finger (by the balloon 22 in the example of FIG. 1). In the example of FIG. 1A, when the initial value of the character to be displayed is “a”, which is the first of the alphabetical arrangement, regardless of the position where the user touches (starts the slide) on the slide bar 21. However, the present invention is not limited to this, and the character corresponding to the position touched by the user among the characters of the Japanese syllabary array assigned in advance to the slidable range of the slide bar 21 is shown. May be displayed as an initial value (absolute position mode).

  In the state of FIG. 1A, when the user wants to input “re” next time, for example, “re” is behind the currently displayed “a” in a Japanese alphabet, so the user Slides the finger in the right direction (positive direction in the slide bar 21). At this time, the position of the slide bar 21 (the position of the finger) or the slide amount is detected, the display position of the balloon 22 is slid according to the position, and the characters displayed in the balloon 22 are sequentially switched. For example, on the slide bar 21, characters to be included here are assigned at equal intervals to an area between the position where the finger is first touched and the position where the finger is slid to the right as much as possible. A character corresponding to is displayed on the balloon 22.

  As shown in FIG. 1B, when the user slides his / her finger on the slide bar 21 to the position where the desired “re” is displayed in the balloon 22, next, “re” is selected. To do so, slide your finger over the balloon 22. When the portable terminal 1 detects that the balloon 22 is touched, as shown in FIG. 1C, it treats the corresponding character (“re”) as input. When inputting the next character, the user returns his / her finger on the slide bar 21 as shown in FIG.

  Next, when the user wants to input “ba”, for example, “ba” is ahead of the currently displayed “re”, so the user moves his finger to the left. Slide in the negative direction of the slide bar 21. When the user slides his / her finger to the position where “ha” is displayed in the balloon 22, the portable terminal 1 displays “ha” by the balloon 22 as shown in FIG. “B” is also displayed. In this way, when there are muddy point and semi-turbid point candidates, these are displayed as selectable candidates by a plurality of balloons 22. The same applies to stuttering and prompting sounds such as “ya” and “nya”, “tsu” and “tsu”, and upper and lower case letters such as “A” and “a”. The user can select from the displayed candidates by touching the balloon 22 displaying the desired character, as in the example of FIG.

  FIG. 2 is a diagram showing an outline of an example of a technique for switching the character type and input mode to be input. In the example of FIG. 2A, as in FIG. 1, the initial value of hiragana is set as the character type. Here, in order to switch the character type, in the present embodiment, for example, the user moves his / her finger in a direction orthogonal to the slide direction of the slide bar 21 as if the columnar slide bar 21 is rotated along the axis (FIG. 2). In this example, it is moved so as to play upward or downward (hereinafter, this operation may be described as “flip”). When this operation is detected, the portable terminal 1 switches the character type to be displayed from hiragana to alphabet as shown in FIG. It should be noted that even if the direction is orthogonal, it has a certain width and may be handled as the orthogonal direction as long as the angle is within a predetermined range with respect to the slide bar 21 (for example, 60 degrees to 120 degrees). is there.

  Further, by repeatedly flipping and rotating the slide bar 21 a plurality of times, the character types may be sequentially switched cyclically, for example, hiragana → alphabet → number → special character → katakana → hiragana →. The character type may be switched in the reverse order by flipping in the reverse direction. Further, in order to notify the user that the character type or the input mode has been switched, for example, the appearance of the slide bar 21 may be changed as shown in FIG. The notification method of the current character type and input mode is not limited to this, and for example, a small display area may be provided on the side of the slide bar 21 to display the selected character type and input mode.

[System configuration]
FIG. 3 is a functional block diagram showing an outline of a configuration example of the character input reception system in the present embodiment. The character input acceptance system is configured by the portable terminal 1 described above, and the functional block diagram shown in FIG. 3 is an extracted part of the functions of the portable terminal 1 related to the character input acceptance method of the present embodiment. It is. The character input reception system includes, for example, a character input control unit 10 that is implemented by a software program or the like that operates on an OS (not shown), a touch panel 20, and a screen display unit 30. The screen display unit 30 is implemented as hardware such as a software program or an integrated circuit. For example, the screen display unit 30 controls the touch panel 20 to display screen data in the display area.

  The character input control unit 10 further includes, for example, a finger position detection unit 11, a finger position information analysis unit 12, a finger stationary time detection unit 13, a finger movement direction analysis unit 14, a finger movement speed analysis unit 15, a bar switching / information control unit. 16, a character type control unit 17, a character information display unit 18, a character selection unit 19, and the like.

  The finger position detection unit 11 detects the position (coordinates) where the finger is touched when the user performs a touch or gesture operation on the touch panel 20. The finger position information analysis unit 12 determines whether the position of the touched finger is on the slide bar 21, the balloon 22, or another area. If it is on the slide bar 21, its relative position and slide amount (for example, what percentage of the entire length of the slide bar 21 is located) may be obtained. When the position of the finger is on the slide bar 21, the candidate character displayed on the balloon 22 is switched. When the finger is on the balloon 22, the character selection process is performed. The finger rest time detection unit 13 acquires a duration time during which the finger is touched on the slide bar 21 or the balloon 22.

  The finger movement direction analysis unit 14 analyzes the movement direction of the finger on the touch panel 20 and moves in the horizontal direction (in the example of FIGS. 1 and 2) (when the slide bar 21 is slid). 2 performs the process of switching the candidate characters to be displayed in the balloon 22, and when moving in the vertical direction, the information is passed to the finger movement speed analysis unit 15 described later, and the flip operation shown in the example of FIG. It will be determined whether or not. When the finger is moving in the vertical direction, the finger movement speed analysis unit 15 determines whether or not the speed is equal to or greater than a certain value. If the finger is equal to or greater than the certain value, the finger movement speed analysis unit 15 determines that the flip operation has been performed.

  When the finger movement speed analysis unit 15 determines that the flip operation has been performed, the bar switching / information control unit 16 switches the color of the slide bar 21 and the character type control unit 17 to be described later. Notify The character type control unit 17 switches the character type of the character displayed in the balloon 22 in accordance with the switching of the color or the like of the slide bar 21 by the bar switching / information control unit 16.

  The character information display unit 18 controls the display position of the balloon 22 based on information from the finger position information analysis unit 12 and the character type control unit 17, and controls the character displayed on the balloon 22 according to the character type (determination of the character). And determination of candidates such as semi-turbid point, muddy point, upper-case letter, and lower-case letter). Based on the information from the finger position information analysis unit 12 and the finger stationary time detection unit 13, the character selection unit 19 detects that the character displayed in the balloon 22 has been selected by the user's touch operation and is selected. The input result is displayed on the touch panel 20 via the screen display unit 30 as if a character has been input.

[Process flow]
FIG. 4 is a flowchart showing an outline of an example of the flow of processing of the character input acceptance method of this embodiment. As an initial process, the portable terminal 1 first displays the slide bar 21 at a predetermined position on the touch panel 20 and starts a character input reception process from the user. Then, the finger position detection unit 11 and the finger position information analysis unit 12 are started. For example, it is detected that a finger has been touched on the slide bar 21, and the position on the slide bar 21 is acquired (S01). Here, for example, it can be obtained as a relative position or a slide amount with respect to the entire length of the slide bar 21.

  Next, after confirming the current character type (initial value is the initial value) by the character information display unit 18 (S02), the initial value of the character with the corresponding character type is displayed by the balloon 22 at the position where the finger on the slide bar 21 is touched. Is displayed (S03). As described above, the initial value of the character may be the first character of the selectable character array in the current character type (for example, “A” in the case of hiragana) (relative position mode), or the slide bar 21. In the arrangement of characters assigned in advance to the slidable range, a character corresponding to the position touched by the finger may be used (absolute position mode).

  Thereafter, the finger movement direction analysis unit 14 determines whether or not the finger is moving in the horizontal direction (S04). If the finger is moving in the horizontal direction (when the slide bar 21 is sliding), the finger position is determined. The amount of movement is acquired based on information from the information analysis unit 12 and the like, and the display position of the balloon 22 is moved by the character information display unit 18 and the character displayed on the balloon 22 is switched accordingly (S05). After switching, it returns to step S04 and repeats said process.

  If it is determined in step S04 that the finger has not moved in the horizontal direction, it is determined whether or not the finger position has moved above the balloon 22 based on information such as the finger position information analysis unit 12 (S06). If it is placed on the balloon 22, the character selection unit 19 then moves the finger on the balloon 22 for a certain time (for example, 0.5 seconds or more) based on information such as the finger rest time detection unit 13. It is determined whether it is placed (S07). If the finger has been placed and the predetermined time has not elapsed, the process returns to step S04 and the above processing is repeated. On the other hand, if the finger is placed for a certain period of time or longer, the character displayed in the balloon 22 is assumed to be selected and displayed as an input result on the touch panel 20 (S08), and the input acceptance process for one character is terminated. . Further, when accepting character input, the process may be repeated from step S01.

  If it is determined in step S06 that the finger is not on the balloon 22, that is, the finger is stationary on the slide bar 21, has moved to a different area from the display area of the slide bar 21 or the balloon 22, or has left the touch panel 20. If so, it is next determined whether or not a flip operation has been performed based on information such as the finger movement speed analysis unit 15 (S09). When the flip operation is performed, the bar switching / information control unit 16 and the character type control unit 17 switch the current character type setting and the character displayed in the balloon 22 according to the character type switching order (S10), and the input reception process Quit once. When further character input is accepted with the character type after switching, the process may be repeated from step S01.

  If it is determined in step S09 that the operation is not a flip operation, then it is determined whether or not the finger is away from the touch panel 20 for a certain time (for example, 3 seconds) based on information from the finger position detection unit 11 or the like. (S11). If the finger has not been separated for a certain time or longer, the process returns to step S04 with characters displayed on the balloon 22 and waits for the next operation by the user. If the distance is longer than a certain time, the display of the balloon 22 is deleted (S12), and the character input acceptance process is terminated.

  As described above, according to the character input receiving method of the present embodiment, the slide bar 21 is displayed and characters that can be selected in the movable range compared to the case where the virtual keyboard is displayed on the screen. By assigning, the area occupied by the entire display area can be significantly reduced for the area for displaying and operating the character candidates. Further, for example, by switching the character types that can be selected by the slide bar 21 by a flip operation, it is possible to deal with a plurality of character types with one slide bar 21, and it is possible to prevent an increase in the occupied area. Further, by combining the character selection by the slide bar 21 and the balloon 22 and the character type switching by the flip operation, it becomes possible to input characters efficiently with a simple operation with one finger.

<Embodiment 2>
In the character input receiving method according to the first embodiment, input candidates to be displayed on the balloon 22 based on an arrangement (for example, in Japanese alphabetical order) predetermined for each character type according to the position of the finger on the slide bar 21. Although the character has been determined, the character input acceptance method according to the second embodiment of the present invention is based on the past input frequency in addition to the input candidate character determination method as described in the first embodiment. By providing a prediction mode that dynamically controls the determination of input candidate characters, the input efficiency can be further improved.

  FIG. 5 is a diagram showing an outline of an example of a character input receiving method according to the second embodiment of the present invention. In FIG. 5A, when it is detected that the user first touched the slide bar 21 with a finger, the initial value of the character displayed in the balloon 22 is different from the example of the first embodiment, and the character input in the past. The character with the highest frequency (“ki” in the example of FIG. 2) is displayed as a prediction candidate.

  Here, as shown in FIGS. 5B and 5C, the user selects and inputs “ki” in the same procedure as in the first embodiment, and the user slides his / her finger to the left. In this case, for example, if the first word “ki” that has been frequently input by the user is “kion”, regardless of the amount of finger movement, FIG. Next, “o” is displayed as a prediction candidate, as shown in FIG. On the other hand, when the user slides his / her finger to the right, for example, if the first word “ki” that has been frequently input by the user is “Kyo”, the amount of finger movement will be Regardless, as shown in FIG. 5D-2, next, “yo” is displayed as a prediction candidate.

  For example, in the state shown in FIG. 5D-2, when the user wants to input “Kyoyo” instead of “Kyo”, the user slides his / her finger further to the right (that is, adopts the displayed prediction candidate). ), The prediction mode based on the past input frequency is canceled, and based on the currently displayed “yo (yo)” as shown in FIG. Are displayed as candidates ("n" in the example of FIG. 5E). In order to realize such prediction, the portable terminal 1 accumulates the number of times of input in the past for each selectable character or input word and holds it in a memory table or file (not shown). I shall keep it.

  Further, in order to improve the prediction accuracy of candidates, for example, in addition to the prediction based on the input frequency as described above, context information such as processing time and season (date) can be taken into consideration at the time of prediction. For example, "Hello" and is in a state of high input frequency of the word "Good evening", if you select a character in the order of "child" → "I" on the basis of the prediction candidate, then the user is a finger in the left direction slide Then, when the time is during the day, “ni” is displayed as a prediction candidate, but at night, “ba” can be displayed as a prediction candidate.

  In addition to time and date, for example, context information that can be acquired by the portable terminal 1 such as position information and temperature by GPS (Global Positioning System) can be used for prediction. In order to realize such prediction, in the portable terminal 1, for example, in addition to the input frequency information for each word, the context information when these are input, the prediction candidate word, etc. are stored. Judgment conditions for selection can be set.

  As described above, according to the character input acceptance method of the present embodiment, when the user touches the slide bar 21 with a finger and slides it, the touch position of the finger and the movement amount at the time of sliding are determined. Regardless, it is possible to greatly improve input efficiency by predicting and displaying input candidate characters based on past input frequencies of characters and words. Further, when determining input candidate characters, in addition to the past input frequency, the use of context information that can be acquired by the portable terminal 1 such as time and date can further improve the prediction accuracy. Can do.

  Note that the various functions in the character input reception method shown in the first and second embodiments described above are set to information such as valid / invalid and valid contents in a file in advance, and the contents are changed. Etc. may be performed later.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. Needless to say. For example, the above-described embodiment has been described in detail for easy understanding of the present invention, and is not necessarily limited to the one having all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. . Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.
