Description

  The present invention relates to a data input device for determining input data based on an operation detected by a detection unit and inputting data.

  Conventionally, as this type of data input device, for example, there is a one-hand kana character input system disclosed in Non-Patent Document 1. In this character input system, the touch panel surface of the portable information terminal is divided into two consonant key input areas and one vowel key input area. Kana character input is performed by performing a tap on a vowel key input area or a flick operation in four directions following a tap on a consonant key input area or a flick operation in four directions. Further, following the input of the two strokes, the kana character is made muddy, semi-voiced, and lowercase by performing a flick operation on the vowel key input area.

  FIG. 4 is a flowchart schematically showing the contents of the input data discrimination process executed by the computer program stored in the ROM constituting the data input device according to the first embodiment.

  In the input data discrimination process, the CPU constituting the input data discrimination unit 3 first reads the character table of the input language to be referred to in the character input from the ROM in step (hereinafter referred to as S) 101, and refers to the RAM. Set to area. In the initial setting, the character table shown in FIG. 3A for Japanese input is set. Next, in S102, the CPU determines whether or not an operation is detected on the touch panel 2. If the determination result in S102 is NO and there is no operation, the system waits until there is an operation.

  If the determination result in S102 is YES and an operation is detected, it is then determined in S103 whether or not the operation is a character input gesture operation. If the determination result in S103 is YES and the operation is a character input gesture operation, then in S104, it is determined whether or not the character input gesture operation is for line designation. If the determination result in S104 is NO and the character input gesture operation is not a line designation operation, the process waits until a line designation operation is detected. On the other hand, if the determination result in S104 is YES and the character input gesture operation is for line designation, next, in S105, the line data of the character corresponding to the detected line designation gesture operation is selected. . For example, if the detected row designation gesture operation is a linear slide operation in the downward direction of the touch that constitutes the row designation operation group corresponding to the row data of the row, the row data of the row Is selected.

  Next, in S106, it is determined whether or not a column-designated character input gesture operation has been detected. If the determination result in S106 is NO and no column-designated character input gesture operation is detected, the process waits until a column-designated character input gesture operation is detected. On the other hand, if the determination result in S106 is YES and the character input gesture operation is for column designation, next, in S107, the character string data corresponding to the detected column designation gesture operation is selected. . For example, if the detected column specifying gesture operation is a linear slide operation to the left of the touch that forms a kana character string specifying operation group corresponding to the column data of the column, Data is selected.

  Next, in S108, a character determined by the row data selected in S105 and the column data selected in S107 is determined, and the character is set as input data. For example, the character “ku” determined by the row data of the row selected in S105 and the column data of the column C selected in S107 is determined, and the character “ku” is set as input data.

  If the determination result in S103 is NO and the detected operation is not a character input gesture operation, it is next determined in S109 whether or not the input gesture operation is a function gesture operation. If the determination result in S109 is YES and the input gesture operation is a function gesture operation, then in S110, a function corresponding to the function gesture operation is executed. For example, when the function gesture operation is a gesture operation in which the touch is slid upward with respect to the touch panel 2 and then the slide is folded clockwise, the table shown in FIG. The CPU performs the function of making the sound muddy ('), lowercase (small), or semi-turbid (°). At this time, if the input data is, for example, “ku”, “ku” is converted into “gu” of muddy sound. For example, when the input data is “ha”, “ha” is converted into “ba” of muddy sound, and when the same function gesture operation is detected again after that, “ba” is changed to “pa” of semi-turbid sound. Is converted to. For example, when the input data is “tsu”, “tsu” is converted into “zu” of muddy sound, and when the same function gesture operation is detected again thereafter, “zu” is a lower case “tsu”. Is converted to

  After the process of S108 or S110 is completed, the process returns to S102, and the processes of S102 to S110 are repeated.

  If the determination result in S109 is NO and the input gesture operation is not a function gesture operation, it is next determined in S111 whether or not the input gesture operation is an input language conversion gesture operation. If the determination result in S111 is NO and the input gesture operation is not an input language conversion gesture operation, the process returns to S102. On the other hand, if the determination result in S111 is YES and the input gesture operation is an input language conversion gesture operation, the process returns to S101. In the processing of S101, the gesture operation detected on the touch panel 2 is set depending on whether the operation is to slide clockwise as shown by the trajectory 11 shown in FIG. Change the language of the character table.

  FIG. 5A shows an English input character table provided in the ROM of the data input device of the first embodiment.

  In this English input character table, each gesture operation is associated with each alphabet data. The data is grouped into a row data group composed of a plurality of rows of data and a column data group composed of a plurality of columns of data. Specifically, the row data groups are grouped into row data groups composed of AEIOU rows. The column data groups are grouped into a four-column data group composed of ABCD columns and a three-column data group composed of LMN columns.

  Gesture operations are also grouped into a plurality of operation groups each composed of a plurality of gesture operations, and corresponding to each column of the column data group and a row designation operation group composed of a plurality of operations corresponding to each row of the row data group. It is grouped into a column specification operation group consisting of multiple operations. Specifically, the line designation operation group includes a linear slide operation in the up, down, left, and right directions corresponding to the A line, E line, I line, and O line of touch on the touch panel 2, and the U line. It is grouped into a row designation operation group consisting of a corresponding one tap operation. The column designation operation group includes a four-column designation operation group composed of linear slide operations in the upward, downward, left, and right directions corresponding to the A column, B column, C column, and D column of touch on the touch panel 2. , L columns, M columns, and N columns, which are grouped into three column designating operation groups in which the touch is slid upward, downward, and leftward with respect to the touch panel 2 and then the slide is folded clockwise.

  The grouping of the data group and the gesture operation group is also performed by utilizing the characteristics of the language and the gesture operation group that constitute the data group. In the case of this example, the data group is divided into groups such that the alphabets constituting the English short vowel AEIOU are positioned at the head of each line data. Like the Japanese table in FIG. 3A, gesture operation groups are grouped by adding arrangements based on operations that are easy to understand and easy to remember for humans that slide in opposite directions in the vertical and horizontal directions. ing. Each data group is associated with a different gesture operation group, and data constituting each data group is associated with an operation constituting an operation group associated with each data group.

  Specifically, the row data group is associated with the row designation operation group, and the row data constituting the row data group is associated with the gesture operation constituting the row designation operation group. That is, the A row data constituting the row data group is a linear slide operation in the upward direction of the touch on the touch panel 2, the E row data is a linear slide operation in the downward direction of the touch, and the I row data is a touch of the touch. A linear slide operation in the left direction, the O row data is associated with a straight slide operation in the right direction of the touch, and the U row data is associated with one tap operation.

  The 4-column data group is associated with the 4-column designated operation group, the 3-column data group is associated with the 3-column designated operation group, and the column data constituting the 4-column data group is associated with the 4-column data group. Gesture operations that constitute a four-column designation operation group, and column data that constitute a three-column data group are associated with gesture operations that constitute a three-column designation operation group associated with the three-column data group.

  That is, the A column data constituting the four column data group is a linear slide operation in the upward direction of the touch constituting the four column designation operation group, and the B column data is a linear slide operation in the downward direction of the touch. The C column data is associated with a linear slide operation in the left direction of the touch, and the D column data is associated with a linear slide operation in the right direction of the touch. Further, the L column data constituting the three column data group is a gesture operation for forming a three column designation operation group, which is a gesture operation of folding the slide clockwise after sliding the touch panel 2 upward. The gesture operation for folding the slide clockwise after sliding the touch in the downward direction, and the N-column data are associated with the gesture operation for folding the slide clockwise after sliding the touch in the left direction.

  In the data discrimination processing for English, row data and column data are selected by the processing of S103 to S107 in FIG. 4, and the alphabet of characters determined by the selected row data and column data is set as input data in S108. The

  In the above English input, if a linear slide operation is performed in the upward direction, the A row group data “ABCD” may be determined as input data and input. In addition, if a linear slide operation is performed in the downward direction, the E row group data “EFGH” is performed. If a linear slide operation is performed in the left direction, the I row group data “IJKLMN” is performed, and the linear slide operation is performed in the right direction. Then, the O row group data “OPQRST” may be discriminated as the input data and the U row group data “UVWXYZ” may be discriminated as the input data when the center is tapped. When the number of input characters is large, the number of gesture operations increases, which is a learning burden on the user. However, a simple input device can be configured by associating the group data grouped as described above with the gesture operations.

  In Chinese kanji input, etc., it is possible to realize language input that is easy to input by human intuition by combining data and operations by combining Chinese kanji features and operation features. As illustrated in FIG. 5B, a stroke in Chinese is one of the elements that constitute a Chinese character and is the smallest unit. By making use of this stroke and aligning the stroke direction of the stroke that constitutes the minimum unit of kanji and the direction of gesture operation as illustrated in FIG. 5B, for example, intuitive gesture operation characteristics and stroke Characters are fused and kanji can be input intuitively.

  According to such a data input device of the present embodiment, when a character input operation is detected by the touch panel 2 in the process of S104, the detected character input stored in the data storage unit in the process of S105. The input data discriminating unit 3 identifies a row designation operation group including an operation and a row data group associated with the row designation operation group. Then, one row data stored in the data storage unit in association with the character input operation detected by the touch panel 2 is selected from the identified row data group. In addition, when a touch panel 2 detects a certain character input operation and another character input operation in the process of S106, a column including the detected another character input operation stored in the data storage unit in the process of S107. The input data determination unit 3 specifies the designated operation group and the column data group associated with the designated column operation group. Then, one column data stored in the data storage unit in association with another character input operation detected by the touch panel 2 is selected from the identified column data group. The input data is data determined by the selected row data and column data in the process of S108.

  Data and operations are grouped as in the data input device of the present embodiment and stored in the data storage unit as a data group and an operation group, whereby various data can be specified by the input data determination unit 3. . As a result, a data input device capable of inputting various data, not limited to 50 types of Japanese, is provided.

This is the same as the data input device.

  The Japanese input character table in the data input device according to the first modification has no English characters, but has muddy sound / semi-voiced sound / stuttering / lowercase data. For this reason, in order to identify these data, a new data row group, a first extended column data group, and a second extended column data group are newly provided. Further, a hash line designation operation group configured by a counterclockwise gesture operation corresponding to the shear line data group, and a first extension column designation configured by a clockwise gesture operation corresponding to the first extension column data group. Corresponding to the operation group and the second extension row data group, there is a second extension row designation operation group configured by a counterclockwise gesture operation. Further, as a gesture operation group corresponding to the row data group, a clockwise gesture operation is used instead of the stop → slide gesture operation in the first embodiment.

  In the first modification, the Japanese input character table has muddy sound / semi-voiced sound / stuttering / lowercase data. Therefore, the input data in the function correspondence table shown in FIG. The function to make (small) or semi-turbid sound (°) is not used.

  The hya line data group is made up of hya, ca, sha, and char lines, and is associated with the hya line designation operation group. Each of the first extension column data group and the second extension column data group is composed of an eye way column, and is associated with the first extension column designation operation group and the second extension column designation operation group, respectively.

  The hya line designation operation group corresponds to the hya line, ca line, sha line, and char line, and slides the touch in the up, down, left, and right directions with respect to the touch panel 2 and then folds the slide counterclockwise. Consists of clockwise gesture operation. In addition, the C line designation operation group folds the slide clockwise after sliding the touch in the upward, downward, left, and right directions with respect to the touch panel 2 corresponding to the Ha line, the Ma line, the Ya line, and the La line. It consists of a clockwise gesture operation and two tap operations corresponding to the Wa line.

  In addition, the first extended row designation operation group slides clockwise after sliding the touch in the up, down, left, and right directions with respect to the touch panel 2 corresponding to row a, row b, row c, and row d. It consists of a clockwise gesture operation that folds and two tap operations corresponding to the row E. The second extended row designation operation group is counterclockwise after the touch is slid in the up, down, left, right direction with respect to the touch panel 2 corresponding to the row A, row B, row C, row D. It consists of counter-clockwise gesture operation to fold the slide and three tap operations corresponding to the row E.

  In the data discrimination process using such a character table, the line data and the column data are selected by the processes of S103 to S107 in FIG. 4, and the Japanese characters / numbers of the characters determined by the selected line data and column data are selected. Is set as input data in S108.

  FIG. 7 is a diagram showing an experimental method and experimental results of an experiment verifying the practicality of Japanese data input using the data input device according to the first modification of the first embodiment.

  In this experiment, the Japanese data input (Gesture) using the gesture operation input according to the first modification of the first embodiment and the flick operation input by touching the software keyboard displayed on the touch panel screen. Japanese data input using Flick (Flick) and Japanese data input using keyboard operation keypad (Keyboard) were compared. As the input Japanese, I repeatedly input it using the same sentence, "The mountain has turned red, so why don't you go to Nikko Toshogu to take pictures of autumn leaves?" As shown in FIG. 7A, the above sentence was input five times in one set as shown in FIG. 7A, and after one sentence was input once, a 30-second break was taken. For each input method, the number of sets shown in FIG. 7B was set in consideration of the difference in proficiency level. In other words, the lower the proficiency level, the greater the number of sets. In the gesture input method using the gesture operation, as shown in FIG. 7C, in the case of 1 to 10 sets of input, the guidance of the input method of the gesture operation is displayed on the touch panel surface to present the input method. In addition, with the input of 11 to 25 sets, I was asked to practice blind input to input Japanese without looking at the touch panel surface. In addition, in the case of 26 to 40 sets of input, a complete blind input was made.

  The practicality of Japanese input in this experiment was evaluated from the viewpoint of input time, shortest input time, input speed, number of input errors, and learning effect. The subjects are 10 male college students in their twenties, all of them are right-handed and are proficient in keyboard operation input and flick operation input.

  The input time is composed of an input content confirmation time, which is a time until the input content is determined, and an actual input time when viewed from an ordinary input process. The actual input time is the time until the input operation is completed if blind input is possible. If blind input is not possible, it is time to search for the key and complete the input operation. The gesture input method using the gesture operation does not use an input area such as a key, so it does not include the time for searching for a key with the eyes, and the input time is purely the time until the input operation is completed.

  As a result of the experiment, the average input time of each sentence using the keyboard input method using the keyboard and the flick input method by flick operation did not change much from the first set to the last set. This is thought to be because the subjects are familiar with Keyboard input and Flick input. In addition, although only two subjects A and B can perform the blind input in the keyboard input, the experimental results did not distinguish between those who can perform blind input and those who cannot perform blind input.

  As for the gesture input using the gesture operation, when the sentence input time was averaged every five sets, the result shown in the table of FIG. 7D was obtained. Since 40 sets were performed in total, the number of 5 sets is 8 times, the average input speed (average input time (seconds)) for 5 sets at each time, and the average input when moving from the previous time to the next time The time decrease rate of the time was the numerical value shown in FIG. The average time reduction rate is 10.3%, and the eighth time reduction rate is a low rate of 53.7% with respect to the first time reduction rate. This indicates that there was a learning effect of gesture input using gesture operation.

  The minimum input time for one sentence in each input method is 23.3 seconds for subject A for gesture input, 11.6 seconds for subject C for Flick input, and 11.3 seconds for subject A for keyboard input. there were. The average input time of one sentence for all subjects in each input method was 28.3 seconds for Gesture input, 14.9 seconds for Flick input, and 13.7 seconds for Keyboard input.

  In Flick input, the same sentence is input repeatedly in this experiment, so you can look at the input area of the software key on the touch panel 2 without looking at the input contents. Therefore, in this experiment, Flick input has no fixed time for the input content at the input time, and only the time portion from when the finger reaches the software key until the input operation is completed becomes the input time. Keyboard input is Roman letter input and there are many keystrokes. However, since it is input with both hands, Keyboard input has almost the same input speed as Flick input. The Gesture input experiment was carried out over a period of about 3 weeks, with an average input time of all 10 subjects of 176 minutes for about 3 hours. As a result, Gesture input reached the input speed about half of Keyboard input. As for this gesture input, input guidance is displayed as input assistance at the beginning of the experiment, but it was confirmed that the guidance screen becomes unnecessary by learning. Gesture input allows characters to be input while confirming the input content on the entire screen of the portable information terminal 1, and can realize Japanese input with less load that is not found in the conventional data input method.

  The features of this Gesture input include the following points. First, as described above, it is possible to browse on the full screen of the portable information terminal 1 even during input. In gesture input, data can be input from a touch panel that is mounted on the viewing screen. Therefore, when data is input, it is possible to view the entire screen as before the input without displaying the input screen like a software keyboard. Therefore, it can be considered as an efficient input method suitable for the portable information terminal 1 having a limited display screen. Another point is that there is a degree of freedom of input. By the gesture input, an input display screen such as a software keyboard is not required, and data can be freely input without visualizing software keys. In addition, a gesture that can be input intuitively allows data input without burden without visual recognition of the input area and input operation.

  Another point is that data can be input in various postures. This Gesture input method uses simple gestures and can be applied in various situations in daily life. Data can be input smoothly even in an unstable state where the body moves. In addition, a character can be input with a thumb gesture holding the portable information terminal 1 with one hand. In addition, data can be input using fingers of a hand that is not gripped. If your finger is tired, you can continue typing with another finger. Therefore, it is thought that this is a Japanese input method that can input long documents. When using both hands, input can be performed more efficiently by separating the "row input" and "column input" operations. Furthermore, it is considered that accurate and high-speed data input can be performed while holding the portable information terminal 1 with one hand even in an unstable environment such as moving. Therefore, this Gesture input method can be used anytime and anywhere, and is considered to be a data input method suitable for the portable information terminal 1 of the ubiquitous information society.

  Moreover, the point which can implement | achieve blind input is mentioned. Since the gesture input can be input accurately with a sense of the body, it is not necessary to input while checking the position of the software key unlike the software keyboard input method. That is, blind input can be easily performed in gesture input.

  In addition, it is easy to learn. In this gesture input method, character data is grouped by using “row” and “column” of Japanese grammar, and simple gestures are made to correspond to groups. Thereby, a simple data input method suitable for the touch panel 2 was realized. If a certain amount of time is taken, the user learns the group arrangement rules and the guidance display becomes unnecessary.

  FIG. 8A is a Japanese input character table provided in the ROM of the data input device according to the second modification of the first embodiment, and FIG. 8B is stored in the function correspondence table provided in the ROM. Correspondence between functions and operations.

  The data input device according to the second modified example is different from the data input device according to the first embodiment described above in the Japanese input character table and the function correspondence table provided in the ROM. This is the same as the data input device according to the embodiment.

  In the Japanese input character table in the data input device according to the second modification, there are no letters and numbers. For this reason, there is no stop-> slide gesture operation corresponding to the alphanumeric string data group in the Japanese input character table shown in FIG. 3A of the first embodiment. Further, as a gesture operation group corresponding to the row data group, a counterclockwise gesture operation is used instead of the stop → slide gesture operation in the first embodiment.

  Also in the input data discrimination process using such a character table, the line data and the column data are selected by the processes of S103 to S107 in FIG. 4, and the Japanese characters determined by the selected line data and column data are selected. Is set as input data in S108.

  In the second modification, the function execution process in S110 of FIG. 4 is performed using a function corresponding to the function gesture operation shown in FIG. 8B. This function gesture operation group is composed of clockwise gesture operations. After sliding the touch in the upward, downward, left, and right directions with respect to the touch panel 2, each clockwise gesture operation to release the fingertips cancels the muddy / lowercase function and cancels the input. It corresponds to the function, the backspace function that deletes input data retroactively in the input direction, and the space input function on the keyboard.

  In addition, the clockwise gesture operation that folds the slide clockwise after sliding the touch upward with respect to the touch panel 2 and releases the fingertip after pressing the touch panel 2 strongly without releasing the touch is a semi-turbid sound function. It corresponds. In addition, in the clockwise gesture operation in which the touch panel 2 is slid in the clockwise direction after the touch is slid in the clockwise direction and the fingertip is released after pressing the touch panel 2 strongly without releasing the touch, the input data is input in the order of input. It corresponds to the delete function that deletes in the direction. Also, after sliding the touch to the right with respect to the touch panel 2, fold the slide clockwise, press the touch panel 2 strongly without releasing the touch, and then release the fingertip. ) Supports input function.

  When a finger is placed on the touch panel 2 without releasing the touch after completing one gesture operation corresponding to the backspace function, the CPU automatically deletes a plurality of input data continuously. When a finger is placed on the touch panel 2 without releasing the touch after completing one gesture operation corresponding to the delete function, the CPU automatically deletes a plurality of input data continuously in the input forward direction. . If the touch is slid clockwise with respect to the touch panel 2, and then the slide is folded clockwise, the touch panel 2 is strongly pressed without releasing the touch, and then the finger is moved backward in the direction of the input data. However, a plurality of input data may be automatically and continuously deleted. Also, after sliding the touch panel 2 in the left direction and then folding the slide clockwise, pressing the touch panel 2 strongly without releasing the touch, and then moving the finger in the input data input forward direction, The CPU may automatically delete a plurality of input data continuously in the input forward direction. As for the space input function and the enter input function, after finishing the gesture operation of each input function, if the finger is placed on the touch panel 2 without releasing the touch, the CPU automatically continues the space or enter. input.

  The same effects as those of the first embodiment can be obtained by the data input device according to each modification of the first embodiment described above.

  FIG. 9A shows the contents of the Japanese input character table provided in the ROM of the data input device of the second embodiment of the present invention, and FIG. 9B shows the contents of the English input character table.

  The data input device according to the second embodiment differs from the data input device according to the first embodiment described above in the Japanese and English input character tables provided in the ROM, and the other configurations are the same as those in the first embodiment described above. It is the same as that of the data input device by form.

  In the Japanese input character table having the contents shown in FIG. 9A and the English input character table having the contents shown in FIG. 9B, a plurality of chunk data is obtained by dividing the continuous data into a predetermined number. The data groups are grouped, and each block data group is stored in the data storage unit in association with different position operation combinations of the input position attribute and the operation group. In addition, the gesture operation is stored in the data storage unit in correspondence with each piece of data in the block data group associated with the position operation combination.

  In the Japanese input character table having the content shown in FIG. 9 (a), a plurality of kana chunk data groups divided into each line by taking advantage of the feature that each kana character data constituting Japanese is arranged in line units. The kana chunk data groups are associated with different position operation combinations of the input position attributes of the areas 21 to 25 and the operation groups.

  In other words, the kana data group of the row data includes the input position attribute of the center area 21 and the linear gesture operation group including the linear slide operation in the upward, downward, left, and right directions of the touch on the touch panel 2 and once. Is associated with a combination of position operation and tapping operation. Further, each of the kana data groups of the kana, sagami, tana, and kana data is divided into four areas that can be understood by human intuition up, down, left and right with the center area 21 as the center. Each of the 25 input position attributes is associated with a position operation combination of a straight line gesture operation group and one tap operation. By this association, for example, the character “A” constituting the line data belonging to the input position attribute of the region 21 is touched on the touch panel 2 with a linear slide operation in the upward direction and the character “I” is touched. A straight slide operation to the bottom of the screen, a straight slide operation to the left of the touch for the character “U”, a straight slide operation to the right of the touch for the character “E”, and the character “O” "Is associated with one tap operation.

  In addition, the kana chunk data group of the row data is an input position attribute of the center area 21 and a clockwise gesture that folds the slide clockwise after sliding the touch up, down, left, or right with respect to the touch panel 2. It is associated with a position operation combination with an operation group and one tap operation. Also, each input position attribute of the peripheral areas 22, 23, 24, and 25 in which the kana chunk data groups of the line, the line, the line, and the line data are divided into four equally around the center area 21, and the clockwise direction. Corresponding to a position operation combination with a gesture operation group and one tap operation. By this association, for example, the character “ha” that constitutes the row data belonging to the input position attribute of the area 21 is rotated clockwise after the touch is slid upward with respect to the touch panel 2. Gesture operation, slide the touch downward for the letter “hi”, then fold the slide clockwise, slide the touch left for the letter “fu”, then fold the slide clockwise A clockwise gesture operation, the character “to” is associated with a clockwise gesture operation in which a slide is slid clockwise after sliding the touch in the right direction, and the character “ho” is associated with a single tap operation.

  In the English input character table shown in FIG. 9 (b), each alphabet data constituting English is divided into groups of a plurality of alphabetic chunk data groups that are divided into every five consecutively good cuts. The chunk data group is associated with different position operation combinations between the input position attribute of each area 21 to 25 and the operation group. That is, the alphabetic chunk data group of alphabets A, B, C, D, and E is a straight line composed of the input position attribute of the center area 21 and the linear slide operations in the upward, downward, left, and rightward directions on the touch panel 2. Corresponding to a combination of position operation with a gesture operation group and one tap operation. F, G, H, I, J alphabet, K, L, M, N, O alphabet, P, Q, R, S, T alphabet, U, V, W, X, Y alphabet Each alphabet block data group is a combination of position operations of the input position attributes of the peripheral areas 22, 23, 24, and 25 divided into four equal parts around the center area 21, the straight line gesture operation group, and one tap operation. , Are associated. The last Z of the alphabet is associated with the input position attribute of the peripheral area 25 and the position operation combination of two tap operations.

  As a result of this association, for example, the character “A” that constitutes the English character block data group of A, B, C, D, and E belonging to the input position attribute of the area 21 has a linear shape in the upward direction on the touch panel 2 touch Slide operation, a straight slide operation in the downward direction of the touch for the letter “B”, a straight slide operation in the left direction of the touch for the letter “C”, and a right direction of the touch for the letter “D” A linear slide operation, and a single tap operation is associated with the letter “E”.

  That is, in the data input device according to the second embodiment, in the Japanese input character table, the data grouped into the kana block data group and the operations grouped into the straight line or clockwise gesture operation and the tap operation Are associated with different position operation combinations, and data constituting the kana chunk data group is stored in the data storage unit in association with operations constituting the operation group of each position operation combination. In the English input character table, the data grouped into the English character block data group and the operations grouped into the straight gesture operation and the tap operation are associated with different combinations of position operations. The data constituting the alphabet block data group is stored in the data storage unit in association with the operations constituting the operation group of each position operation combination.

  According to such a data input device according to the second embodiment, when a certain operation is detected by the touch panel 2, the input position attribute and detection of the detected operation areas 21 to 25 stored in the data storage unit. The position operation combination of the operation group including the operated operation is specified by the input data determination unit. In the Japanese input character table, the kana block data group associated with the operation group constituting the specified position operation combination constitutes the specified position operation combination in the English input character table. The alphabet data block data group associated with the operation group is specified by the input data discrimination unit. Then, one data stored in the data storage unit corresponding to the operation detected by the touch panel 2 is selected from the specified kana data group or alphabetic data group, and the selected data is input. Data.

  By grouping the data in this way and storing the grouped chunk data group in the data storage unit in association with different position operation combinations of the operation and the input position attribute, various data can be obtained by the input data determination unit. It becomes possible to specify. Therefore, the present embodiment also provides a data input device capable of inputting various data, not limited to 50 types of Japanese.

  Further, in the data input device according to the first embodiment, in order to input one character data, a two-stroke gesture operation for specifying row data and column data is necessary. However, in the data input device according to the second embodiment, one character can be input by a one-stroke gesture operation. Therefore, according to the second embodiment, a data input device with improved input speed can be provided.

  FIG. 10 shows the correspondence between the data in the character table for Japanese input provided in the ROM and the operation of the data input device according to the first modification of the second embodiment.

Then, one column data stored in the data storage unit in association with another gesture operation detected by the detection unit is selected from the identified column data group. The input data is data determined by the selected row data and column data.

  FIG. 11 shows the correspondence between the data and the operation of the character table for Japanese input provided in the ROM of the data input device according to the second modification of the second embodiment.

  The data input device according to the second modified example is different from the data input device according to the second embodiment in that the ROM includes only a Japanese input character table. It is the same as that of the data input device by embodiment.

  In the Japanese input character table in the data input device according to the second modification, the data is divided into a row data group consisting of a plurality of rows of data and a row data group consisting of a plurality of rows of data and a column data group consisting of a plurality of rows of data. The data is grouped and stored in the data storage unit. Then, one row data group is associated with a gesture operation that is first detected at one input position of the A area by the touch panel 2, and the other row data group is another input of the B area by the touch panel 2. The column data group is stored in the data storage unit in association with a gesture operation detected later by the touch panel 2 at an input position different from the row data group. .

  Further, the gesture operation is first detected at the input position of the area A by the touch panel 2, and the A line designation operation group including a plurality of gesture operations corresponding to the respective lines of the line data group, and the touch panel 2 inputs the B area. A row designation operation group consisting of a plurality of gesture operations corresponding to each row of the row data group detected in advance, and a column data group detected later by the touch panel 2 at an input position different from the row data group. They are grouped into a column designation operation group consisting of a plurality of gesture operations corresponding to each column, and stored in the data storage unit.

  According to such a data input device according to the second modified example, when a gesture operation is first detected by the touch panel 2 at one input position in the area A, the line designation operation group is specified by the input data determination unit 3. Is done. Then, one row data corresponding to the gesture operation detected by the touch panel 2 is selected from the specified row designation operation group. Further, when the gesture operation is first detected by the touch panel 2 at another input position in the B area, the input data determination unit 3 specifies the row designation operation group. Then, one row data corresponding to the gesture operation detected by the touch panel 2 is selected from the identified row designation operation group. Thereafter, when a gesture operation is later detected by the touch panel 2 at an input position different from the row data group, the column specifying operation group is specified by the input data determination unit 3. Then, one column data corresponding to the gesture operation detected by the touch panel 2 is selected from the identified column designation operation group. The input data is data determined by the selected row data and column data.

  Specifically, when the gesture operation is first detected by the touch panel 2 at the input position of the area A, the line designation operation group is specified by the input data determination unit 3. Then, one row data corresponding to the gesture operation detected by the touch panel 2 is selected from the specified row designation operation group. For example, when the gesture operation previously detected at the input position of the area A is a linear slide operation in the downward direction of the touch that constitutes the row designation operation group corresponding to the row data of the row , Row data of the selected row is selected. Thereafter, when a gesture operation is later detected by the touch panel 2 at an input position in the B area different from the row data group, the column specifying operation group is specified by the input data determination unit 3. Then, one column data corresponding to the gesture operation detected by the touch panel 2 is selected from the identified column designation operation group. For example, if the gesture operation detected later at the input position in the area B is a linear slide operation in the left direction of the touch that forms a column designation operation group corresponding to the column data of the column C, Column data for the column is selected. The input data is data determined by the selected row data and column data. For example, kana character “ku” data determined by the row data of the row C and the column data of the column C is used as the input data.

  Further, when a gesture operation is first detected by the touch panel 2 at the input position of the area B, the input data discriminating unit 3 identifies the row designation operation group. Then, one row data corresponding to the gesture operation detected by the touch panel 2 is selected from the identified row designation operation group. For example, when the gesture operation detected first at the input position in the B area is a linear slide operation to the right of the touch, which constitutes the row designation operation group corresponding to the row data of the row. , The row data of the row is selected. Thereafter, when a gesture operation is later detected by the touch panel 2 at an input position in the area A different from the row data group, the column specifying operation group is specified by the input data determination unit 3. Then, one column data corresponding to the gesture operation detected by the touch panel 2 is selected from the identified column designation operation group. For example, if the gesture operation detected later at the input position in the area A is a linear slide operation in the downward direction of the touch that forms a column designation operation group corresponding to the column data of the column A, Column data for the column is selected. The input data is data determined by the selected row data and column data. For example, kana character “ri” data determined by the row data of row A and the column data of row B is used as input data.

  In the second modified example, the column data is grouped into two data groups, the row data is grouped into one data group, and the first detected gesture operation is performed in two columns depending on the input position of the operation. A gesture operation detected later at an input position different from the input position of the column data may be configured to be associated with each column data and associated with the row data.

  The same effects as those of the second embodiment can be obtained by the data input device according to each modification of the second embodiment described above.

  In each of the above-described embodiments and modifications, the case has been described in which a straight gesture operation group, a clockwise or counterclockwise gesture operation group, or the like is an operation group. However, the operation group includes moving and static elements such as fast and slow operations, shape elements such as points, lines, surfaces, straight lines, and curves, hand elements such as one hand and both hands, one, two, three, four, and five. Various operation groups can be formed according to the physical factors such as the number of fingers used, the length of the movement distance of the operation, the moving speed or acceleration, the moving direction, the pressure of the operation, and the positional relationship of the operation. Then, the group of operations to be actually used is determined from the viewpoint of each factor of the operations that can be recognized by the computer and whether or not the operations can be performed by human intuition. By enriching the operation group in this way, it is possible to associate one character with one gesture operation and speed up data input.

  For example, as shown in FIG. 12, four short up / down / left / right linear slide operations and one weak tap operation are composed of five operation groups 26a, four short up / down / left / right clockwise slide operations and An operation group 26b composed of five types of operations of two weak tap operations, an operation group 26c composed of four types of short, up, down, left and right counterclockwise slide operations and three weak tap operations. An operation group 27a composed of four types of long, vertical, left and right linear slide operations and one strong tap operation, and five types of four long vertical and horizontal clockwise slide operations and two strong tap operations. Operation group 27b composed of four operations, four long up / down / left / right counterclockwise slide operations and three strong tap operations In at constituted operating group 27c, a total of 30 (= 5 × 6) an operation group of types of operations can be realized.

  In this case, one character can be associated with one gesture operation by associating one gesture operation with each of the 26 alphabetic characters A to Z. At this time, for example, as shown in FIG. 9B, each alphabetic character is grouped into five data groups, and each gesture operation and each data group are associated with each other as a set. A to E data groups, F to J data groups for the operation group 26b, K to O data groups for the operation group 26c, P to T data groups for the operation group 27a, and U to U for the operation group 27b. By associating the Z data with the upward counterclockwise slide operation of the Y data group and the operation group 27c, it is easy to remember the character input and to input it intuitively.

  Further, by increasing the number of gesture operations in the same manner, one character can be assigned to one gesture operation in the same way for each Japanese kana character input. At this time, as shown in FIG. 9A, for example, kana character data is grouped into data groups for each row, and each gesture operation and each data group are associated with each other as a set so that character input can be easily remembered. And it can make it easy to input intuitively.

  In each of the above-described embodiments and modifications, the case where the operation is a gesture operation using a human finger has been described. However, the operation may be a gesture operation using a human hand, a foot, a head, a body, an eye or the like, a writing operation with an electronic pen, a keyboard key operation, or a mouse mouse operation.

  For example, in the keyboard 31 shown in FIG. 13, the group of the Ctrl key 32, the Alt key 33, and the Shift key 34 and the group of the up, down, left, and right arrow keys 35 are combined to provide a plurality of the above-described embodiments. An operation group similar to an operation group composed of linear slide gesture operations can be configured. That is, three operations: a group of the Ctrl key 32 and the up / down / left / right arrow keys 35, a group of the Alt key 33 and the up / down / left / right arrow keys 35, and a group of the Shift key 34 and the up / down / left / right arrow keys 35. Groups can be configured. Then, by storing each of these operation groups in the data storage unit in correspondence with each data group, even when the keys of the keyboard 31 are used, the gesture operation group described in the above embodiments is considered. Using this, a similar data input device can be realized.

  Moreover, although each said embodiment and each modification demonstrated the case where the detection part which detects operation was the touch panel 2, a detection part is not restricted to this. Depending on the operation to be detected, a touch pad, gyroscope, geomagnetic sensor, camera, infrared ray, pressure-sensitive touch sensor, radar, or the like can be used as the detection unit. By using these detection units, a device such as a ring type or glove type wearable terminal or a leap motion capable of operating a computer without using a mouse or a screen touch by a hand gesture can be used as an input device.

  In each of the above embodiments and modifications, the case where the data input device is applied to the portable information terminal 1 such as a smartphone or a tablet has been described. However, the data input device is also applied to an electronic book, a game machine, or the like. It can be applied.

  Even with each of these configurations, the same operational effects as the above-described embodiments and modifications can be obtained.
