Description

  The present invention relates to a character input device that performs character input using a touch panel.

  In recent years, mobile terminals such as mobile phones that require a screen-integrated touch panel are increasing. A screen-integrated touch panel can eliminate the need for a keyboard that is a character input device, and the miniaturization of portable terminals is progressing.

  By the way, in character input using a touch panel, as shown in FIGS. 10A to 10D, guide display indicating input characters is generally performed when input is performed. Specifically, when the finger is released, or after the finger is released, it disappears after a certain time, and when touched again, the guide of the corresponding character is displayed again. This guide display is used to confirm what character the user himself / herself intends to input and also to reconfirm whether or not the character as intended is input.

  In Patent Documents 1-3, when the user touches the first-layer software keyboard, a second-layer software keyboard, that is, a guide display is performed, and a technique for inputting characters based on the sliding direction and movement amount of the touched finger is disclosed. Has been. In Patent Document 4, when the user touches the first-layer software keyboard, the second and third-layer software keyboards, that is, a guide display is performed, and a technique that can easily switch the type of characters to be input. It is disclosed.

JP 2010-33272 A (released on February 12, 2010) JP 2002-108543 A (published on April 12, 2002) JP 2008-282380 A (published November 20, 2008) JP 2011-233051 A (published November 17, 2011)

  By the way, the time during which this guide is displayed (guide display time) is usually fixed.

  However, if the guide display time is fixed, the user's comfortable input may be impaired. Specifically, if the guide display time is too short, the user must check the field in which the actual character is input in order to check the input character, and the line of sight is between the keyboard and the input field. The amount of movement will increase. On the other hand, when the display time is too long, the guide display becomes an obstacle when the user inputs the next character. Therefore, it is necessary to turn off the guide display at an appropriate timing.

  However, since the appropriate timing for turning off the guide display varies depending on the user and the usage scene, if the guide display time is fixed, there is a problem that a comfortable character input cannot be performed depending on the user or the usage scene.

  The present invention has been made in view of the above-described problems, and its purpose is to provide a character input device, a guide display time setting method, a guide display time setting program that allows a user to always comfortably input characters, And a computer-readable recording medium on which a guide display time setting program is recorded.

The character input device of the present invention is a character input device in which a touch panel is provided on the surface of a screen for displaying characters, and guide display for performing character input guidance is performed at the time of character input by the touch panel,
An input unit for accepting user character input via the touch panel;
A character input speed measuring unit for measuring the speed of character input received by the input unit;
And a display time setting unit that sets a display time of the guide display according to the character input speed measured by the character input speed measuring unit.

  According to the above configuration, the guide display display time is set according to the character input speed, so that the guide display is performed in a time appropriate for the user. That is, if the character input speed is slow, the guide display time is increased accordingly, and if the character input speed is high, the guide display time is shortened accordingly, so that the user can always comfortably input characters. There is an effect that can be done.

  The specific setting of the guide display time is performed as follows.

It has a database that stores character input speed and guide display display time in association with each other.
Upon receiving the character input speed measured by the character input speed measuring unit, the display time setting unit reads the display time associated with the character input speed with reference to the database, and reads the read display time. To the guide display time.

A database that associates a character input speed, a display time of a guide display, and a character input scene obtained by combining input conditions determined at the time of character input;
A character input scene determination unit that determines a character input scene when the input unit receives character input;
When the display time setting unit receives the character input speed measured by the character input speed measuring unit and the character input scene determined by the character input scene determination unit, the character input speed and The display time associated with the character input scene is read, and the read display time is set as the guide display time.

  Here, the character input scene refers to a combination of conditions for inputting characters. That is, by recording the character input speed individually according to the character input scene and setting an appropriate guide display time according to the character input scene, the user can perform more comfortable character input.

  The input conditions include, for example, input field attributes such as passwords, e-mail addresses, and mail texts, types of characters to be input such as Japanese, alphabet, and numbers, and types of keyboards such as 12 keyboards and QWERTY keyboards. , Characters, symbols, button types such as setting buttons, and the like.

  According to said structure, the display time of a guide display can be changed automatically and appropriately according to a character input scene.

A storage unit for storing the character input speed measured by the character input speed measuring unit;
A database that correlates character input speed and guide display time,
The display time setting unit reads a predetermined number of character input speeds stored in the storage unit, obtains an average value of the character input speeds, refers to the database, and is associated with the character input speed of the average value. The read display time is read out, and the read display time is set as the guide display time.

  Thus, by setting the guide display time from the average value of the accumulated character input speed, data (statistical data) indicating the relationship between the user's character input speed and the guide display time is used, and the user always There is an effect that it is possible to input characters comfortably.

  However, if extremely long numerical values are recorded, the accuracy of the statistical data is lowered. Therefore, it is necessary to set an upper limit of the numerical values to be recorded so as not to reduce the accuracy of the statistical data.

A character input scene determination unit for determining a character input scene when the input unit receives character input;
A storage unit that stores the character input speed measured by the character input speed measurement unit and the character input scene determined by the character input scene determination unit in association with each other;
It has a database that correlates character input speed, display time of guide display, and character input scene,
The display time setting unit obtains an average value of the character input speeds stored in the storage unit and receives the character input scene determined by the character input scene determination unit. The character input speed of the value and the display time associated with the character input scene are read, and the read display time is set as the guide display time.

  The display time setting unit obtains an average value of character input speeds up to a predetermined number from the latest stored character input speed among the character input speeds stored in the storage unit.

  In this case, an average of character input speeds up to, for example, the 100th character count from the latest accumulated character input speed is taken.

  As described above, since all the character input speeds stored in the storage unit are not averaged, the guide display time can be appropriately changed according to the change in the character input speed of the user.

  The accumulation unit does not accumulate a character input speed faster than a preset character input speed.

  As a result, accumulation of character input speed due to erroneous operation or random character input can be eliminated, so that a more appropriate average value can be obtained.

  The display time setting unit sets a guide display time shorter than the guide display time set according to the character input speed when the user operation received by the input unit is included in a preset operation.

  In this case, since it is considered that the user has sufficiently confirmed which characters are input, it is possible to prevent unnecessary display of the input guide for a long time.

  The present invention is a character input device in which a touch panel is provided on the surface of a screen for displaying characters, and guide display is performed for guiding character input when characters are input by the touch panel. And a character input speed measuring unit that measures the speed of character input received by the input unit, and guides according to the character input speed measured by the character input speed measuring unit. By providing the display time setting unit for setting the display time for display, the user can always comfortably input characters.

<Embodiment 1>
An embodiment of the present invention will be described as follows.

(About outline of character input device)
FIG. 1 is a block diagram showing an outline of a character input device 1 according to the present embodiment.

  As shown in FIG. 1, the character input device 1 includes an input unit 11, a display unit 12, a control unit 13, and a recording unit 14.

  The input unit 11 receives a user input operation performed using a touch panel, a keyboard, or the like, and outputs an operation signal corresponding to the received operation to the guide display control unit 21 of the control unit 13.

  The display unit 12 includes a flat display panel (FDP) such as a liquid crystal display panel or an organic EL panel, and displays a screen image such as a guide display generated by the control unit 13. The display unit 12 is provided with a touch panel on the surface of a display surface (screen) for displaying characters.

  The control unit 13 comprehensively controls the operation of the character input device 1. Details of the control unit 13 will be described later.

  The recording unit 14 includes a storage unit 31 that stores user character input speed and character input scene data, and a guide display time database 32. The character input scene indicates a condition for character input. If the character input scene is different, the user's character input speed tends to change. Therefore, when the character input speed is stored in the storage unit 31, it is stored in association with the character input scene as described above. Details of the character input scene will be described later.

(Control unit 13)
The control unit 13 includes a guide display control unit 21, a character input speed measurement unit 22, a character input scene determination unit 23, a display time setting unit 24, and an average value calculation unit 25.

  The guide display control unit 21 causes the display unit 12 to display a guide for the display time obtained according to the input information received by the input unit 11.

  Here, the input information input to the guide display control unit 21 includes information necessary for obtaining the character input speed of the user and information necessary for specifying the character input scene.

  Accordingly, the input information input to the guide display control unit 21 is output to the subsequent character input speed measurement unit 22 and the character input scene determination unit 23.

  The character input speed measuring unit 22 measures the character input speed from the input information sent from the guide display control unit 21, and uses the measurement result (character input speed data) as the character input scene determination unit 23 and the display time setting unit. 24 is output.

  The character input scene determination unit 23 determines a character input scene from the input information sent from the guide display control unit 21 and the character input speed data sent from the character input speed measurement unit 22, and discriminates the character input scene. The result (character input scene data) is output to the display time setting unit 24 and the storage unit 31 of the recording unit 14. The storage unit 31 stores the character input scene data and the character input speed data in association with each other.

  The display time setting unit 24 records the guide display time associated with the character input speed data from the character input speed measurement unit 22 and the character input scene data from the character input scene determination unit 23 with the recording unit 14. The guide display time database 32 reads the guide display time and outputs the guide display time to the guide display control unit 21.

  The display time setting unit 24 is a guide display time associated with the character input scene data from the character input scene determination unit 23 and an average value of character input speeds obtained by an average value calculation unit 25 described later. Are read from the guide display time database 32 of the recording unit 14 and the guide display time is output to the guide display control unit 21.

  The average value calculation unit 25 receives an instruction from the display time setting unit 24, and from the latest character input speed data among the character input speed data associated with the character input scene stored in the storage unit 31. An average value of a predetermined number of character input speed data is obtained.

  As described above, the storage unit 31 stores the character input speed data associated with the character input scene. However, the storage unit 31 is not limited to such a storage method, and the character input speed data is stored for each character input scene. You may make it accumulate | store in.

  The guide display time database 32 has a character input speed and a guide display display time for each character input scene (A, B, C,...) Obtained by combining the input conditions determined at the time of character input. Are stored in association with each other.

The character input device 1 configured as described above stores the character input speed when the user inputs characters in the storage unit 31 in association with the character input scene, and sets the guide display time using the stored data. Therefore, learning is performed so that a guide display time having a length suitable for the user can always be set. That is, the character input device 1 automatically changes the guide display time based on the learning result so that the guide display time is always suitable for the user.

(Description of character input speed data to be recorded)
The character input speed data recorded in the storage unit 31 will be described below with reference to FIGS.

  Here, three types of examples of character input methods will be described, and character input speed data to be recorded will be described for each.

  FIG. 2 is a diagram showing the case of flick input with a 12 keyboard.

  As shown in FIG. 2A, when a user touches a button to be input, a guide display of characters corresponding to the button is performed. In the case of FIG. 2A, a guide is displayed in which characters are arranged in four directions, up, down, left, and right, centering on the character “NA”.

  As shown in FIG. 2B, an input character is selected by a user flicking, that is, moving a finger in a predetermined direction. In FIG. 2B, the user moves his / her finger in the left direction (direction from “NA” to “TA”), so that the character “NI” in the displayed guide is selected. During the period from (a) to (b) in FIG. 2, that is, during the selection of the flick direction, since guide display is usually performed, the time required for this operation is not recorded.

  Then, as shown in FIG. 2C, the input character is determined when the user lifts the finger from the button. In the case of (c) in FIG. 2, the characters “ni” are displayed in the input area (not shown) of the display unit 12, and the guide display disappears.

  Subsequently, as shown in FIG. 2D, when the user touches a button to input another character, a guide display of the character corresponding to the button is performed. The character input device 1 records the time required for the operation from (b) in FIG. 2 to (d) in FIG. 2 as input speed information. That is, it is received by the input unit 11 described above and is input to the guide display control unit 21. The character input speed is measured by the character input speed measuring unit 22 based on the input information, and the character input scene is determined. The storage unit 31 stores the character input speed data in association with the character input scene.

  FIG. 3 is a diagram showing a case of toggle input in a 12 keyboard.

  As shown in FIG. 3A, when a user touches a button to be input, a guide display of characters corresponding to the button is performed. In the case of FIG. 3A, a guide in which characters are arranged in four directions, up, down, left, and right, centering on the character “NA” is displayed. In this state, the selected character, for example, “NA” in the case of FIG. 3A is displayed in the input area of the display unit 12.

  As shown in FIG. 3B, when the user lifts his / her finger, the input character is determined, for example, the character “NA” is determined in this case, and the guide display disappears.

  As shown in FIG. 3C, the user continues to touch the same button, for example, in the case of FIG. 3C, the “NA” button is touched again. In this case, the input is toggled, and the character displayed in the input area of the display unit 12 changes from “NA” to “NI”.

  The time required from (a) in FIG. 3 to (c) in FIG. 3 is regarded as character selection time by toggle input, and the character input device 1 does not record this time as input speed information.

  As shown in FIG. 3D, when the user lifts his / her finger, the input character is determined. For example, in the case of FIG. 3D, the character “NI” is determined, and the guide display disappears.

  FIG. 3E shows the case where the user touches another button, for example, the “TA” button in the case of FIG. 3E in order to input another character. The character input device 1 sets the time required for the operation from (c) in FIG. 3 to (e) in FIG. 3 as a recording target as input speed information.

  FIG. 4 is a diagram showing the case of QWERTY keyboard input.

  As shown in FIG. 4A, when the user touches a button to be input, a guide display of characters corresponding to the button is performed. In the input area of the display unit 12, the selected character, for example, FIG. In the case of (a), the character “s” is displayed.

  As shown in FIG. 4B, when the user lifts his / her finger, the input character is determined. For example, in the case of FIG. 4B, the character “s” is determined and the guide display disappears.

  As shown in FIG. 4C, when the user touches the button of the character to input another character, a guide display of the character is performed, and the selected character is displayed in the input area of the display unit 12. For example, in the case of FIG. 4C, the letter “a” is displayed.

  The character input device 1 records the time required from (a) in FIG. 4 to (c) in FIG. 4 as input speed information.

  The input speed information (time) obtained for each character input method as described above is sent to the character input speed measurement unit 22 via the guide display control unit 21 shown in FIG. Character input speed is measured. The guide display time is determined in consideration of this character input speed. That is, when the character input speed is high, the above measurement time is also shortened, so that the guide display time is also shortened.

  By the way, while the user is inputting a character, the user thinks about a sentence or performs another thing until the next character is input (for example, between (c) in FIG. 2 and (d) in FIG. 2). As a result, input may be interrupted. If this time is used as the measurement time, the guide display time may not be suitable for the user. That is, when the user's character input speed is fast, it is preferable to shorten the guide display time. However, as described above, if the unnecessary time is also set as the measurement time, the guide display time becomes long, which is convenient for the user. Deteriorate.

  Therefore, an upper limit value of the measurement time is set in advance, and if the character input is interrupted for an excessively long time, the upper limit value may be recorded.

  Further, even for the same user, the character input speed varies depending on the conditions for inputting characters (hereinafter referred to as a character input scene). Therefore, it is preferable to change the guide display time for character input according to the input scene. Hereinafter, a character input scene will be described.

(Description of character input scene)
FIG. 5 is a diagram for explaining changes in character input speed due to differences in character input scenes divided into several categories.

  FIG. 5A is a diagram showing a difference in character input speed in the attribute of the input field. Those that are carefully entered so as not to make mistakes such as passwords and e-mail addresses tend to be slower in input speed than those entered in the e-mail text or notepad.

  FIG. 5B is a diagram showing a difference in character input speed depending on the type of characters to be input. Input of alphabets tends to be slower than Japanese and numbers.

  FIG. 5C is a diagram showing a difference in character input speed for each type of keyboard. Even with the same alphabet input, the 12 keyboard tends to be slower in input speed than the QWERTY keyboard.

  FIG. 5D is a diagram showing a difference in character input speed for each type of button. The input speed of the symbol buttons tends to be slower than the input speed of Japanese and alphabetic character buttons. Also, the input auxiliary buttons such as setting are managed separately from other buttons such as not learning.

  By the way, if all the data is calculated without considering the character input scene shown in FIG. 5, the characteristics due to the above tendency may be lost. In other words, depending on the character input scene, the learning result obtained from the measured character input speed is individually recorded for each character input scene, and the user can set the appropriate guide display time according to the character input scene. Therefore, it is possible to provide a user-friendly character input device.

(Learning cancellation)
Next, learning cancellation will be described with reference to FIG.

  6A is a diagram showing an input state of random character strings in the case of the 12 keyboard 11, and FIG. 6B is an illustration of input states of random character strings in the case of the QWERTY keyboard 11. FIG.

  When an erroneous operation or a deliberate character string is intentionally input, the character string tends to be input at a faster input speed than usual. For example, in the case of FIG. 6A, when a random character string is input by operating the 12 keyboard 11 randomly, the random character string is displayed in the input display area 12a. Similarly, in the case of FIG. 6B, when a random character string is input by operating the QWERTY keyboard 11 in a random manner, the random character string is displayed in the input display area 12a.

  If the character input speed obtained by inputting such a random character string is recorded in the storage unit 31, the guide display time set in the display time setting unit 24 may not be suitable for the user. is there.

  For this reason, for example, when a character string of a predetermined speed or more and a certain value or more is input, for example, when there are five or more characters input within one second, all the input speed information of those character strings is stored. It is desirable to have a learning cancel function to discard.

(Exception handling)
Next, the exception process will be described with reference to FIGS. 2 to 4 used in the description of the character input speed data to be recorded.

  The exception process is a process for shortening the guide display time as a one-time limited operation regardless of the original guide display time (guide display time set by learning). In each character input scene, when the operation time described below is long, it is considered that the user has sufficiently confirmed which character is input, so it is not necessary to display the input guide for a long time. In this case, the above exception processing is performed.

  In the case of flick input on a 12-key keyboard, if the time from when flicking from (b) of FIG. 2 to selecting (c) of FIG. Since it is considered that it has been sufficiently confirmed, exception processing is applied and processing for shortening the guide display time is performed.

  In addition, in the case of toggle input with a 12-keyboard, from FIG. 3C to FIG. 3D, that is, after the toggle input is made by touching the same button, the input character is determined by releasing the finger. When the time until the time is long, it is considered that the user has sufficiently confirmed which characters are input, and therefore exception processing is applied to perform processing for shortening the guide display time.

  Also, in the case of QWERTY keyboard input, it takes a long time from FIG. 4 (a) to FIG. 4 (b), that is, from touching to select an input character to releasing the finger to determine the input character. In this case, since it is considered that the user has sufficiently confirmed which character is input, exception processing is applied to perform processing for shortening the guide display time.

(Guide display time setting process)
The guide display time setting process in the character input device 1 will be described with reference to FIGS.

  FIG. 7 is a flowchart showing a processing procedure in which the character input device 1 sets the guide display time.

  FIG. 8 is a flowchart showing the processing procedure of the input scene discrimination processing in the processing procedure shown in FIG.

  First, the touch of the character input area by the user is detected (step S100). Here, the input unit 11 detects a touch operation from the user.

  Next, the character input device 1 starts IME (Input Method Editor, not shown) (step S101).

  Subsequently, a character input process is performed (step S102). Here, when a user's character input operation from the input unit 11 is detected, the guide display control unit 21 creates information for output to the character input speed measurement unit 22.

  And the said guide display control part 21 determines the presence or absence of exception processing execution (step S103).

  If it is determined that exception processing is to be executed (YES in step S103), the guide display control unit 21 executes exception processing (step S104). Thereafter, the process proceeds to step S105, and the character input speed is measured. Here, the guide display control unit 21 outputs character input information to the character input speed measurement unit 22 to cause the character input speed measurement unit 22 to measure the character input speed.

  On the other hand, if it is determined in step S103 that there is no exception (NO), the process proceeds to step S105, and the character input speed is measured.

  Subsequently, an input scene discrimination process is performed (step S106). The details of the input scene determination process will be described later.

  Subsequently, it is determined whether or not to execute learning cancellation (step S107). Here, the guide display control unit 21 determines whether or not the learning cancel execution is necessary from the character input information obtained from the user operation received by the input unit 11. Here, when it is determined that the learning cancellation is to be executed, the canceling process is executed (step S108). That is, the guide display control unit 21 gives a learning cancel instruction to the character input scene determination unit 23. Specifically, the storage unit 31 is instructed to the character input scene determination unit 23 not to store the character input speed and the character input scene in association with each other. Therefore, in the case of learning cancellation execution, the guide display time setting process is terminated.

  On the other hand, if it is determined in step S107 that the learning cancellation is not to be executed, it is determined whether or not the character input is completed (step S109). If it is determined that the character input has not ended, the process proceeds to step S102, and the character input process is executed again.

  If it is determined in step S109 that the character input is completed, the learning result is recorded (step S110). Here, recording the learning result means that the character input scene determination unit 23 stores the character input speed data and the character input scene in the storage unit 31 in association with each other.

Finally, a guide display time is set based on the learning result (step S111). here,
The display time setting unit 24 instructs the average value calculation unit 25 to calculate the average value of the character input speed data stored in the storage unit 31. The average value calculation unit 25 is included in the learning results from the latest learning result to a predetermined number of learning results (character input speed data associated with the character input scene) stored in the storage unit 31. The average character input speed is obtained and sent to the display time setting unit 24.

  When receiving the average value of the character input speed, the display time setting unit 24 refers to the corresponding guide display time database 32, reads the display time associated with the average value, and sets it as the guide display time.

(Input scene discrimination processing)
FIG. 8 is a flowchart showing the flow of input scene discrimination processing. Here, the input scene is set by determining each category of (a) to (c) of FIG.

  After the character input speed is measured in step S105 shown in FIG. 7, it is first determined whether or not the input field is carefully input (step S200). Here, passwords and email addresses are assumed to be carefully entered, and email text is assumed not to be entered carefully.

  If it is determined that the input field is to be carefully input (YES in step S200), the input field is set to "carefully input" (step S201). If not input (NO in step S200), the input field is set to "other" (step S202).

  Subsequently, it is determined whether or not the input character is Japanese (step S203). Here, it is determined whether or not the input character is Japanese, hiragana or kanji.

  If it is determined that the input character is Japanese (YES in step S203), the input character is set to “Japanese” (step S204), and the process proceeds to step S208.

  On the other hand, if it is determined that the input character is not Japanese (NO in step S203), it is determined whether the input character is alphabetic (step S205).

  If it is determined that the input character is an alphabet (YES in step S205), the input character is set to “alphabet” (step S206), and the process proceeds to step S208.

  On the other hand, if it is determined that the input character is not an alphabet (NO in step S205), the input character is set to “number” (step S207), and the process proceeds to step S208.

  In step S208, it is determined whether the keyboard type is 12 keyboards. If it is determined that there are 12 keyboards (YES in step S208), the keyboard is set to “12 keyboards” (step S209). On the other hand, if it is determined that the keyboard is not 12 (NO in step S208), the keyboard is set to “QWERTY keyboard” (step S210).

  Finally, all the set conditions are combined and set as an input scene (step S211), and the process proceeds to step S107 shown in FIG.

  Note that scene discrimination in character input is not limited to the above. For example, the determination of the input field may be made more finely (for example, whether or not a password is input), or if there are other input characters (for example, Korean characters), it may be added to the determination condition.

  In the present embodiment, an example has been described in which data associated with a character input speed by a user and a character input scene is accumulated as a learning result, and the guide display time is set from the average of the accumulated learning results. In the following second embodiment, an example will be described in which the guide display time is set from the character input speed and the character input scene without obtaining the average of the learning results.
