As shown in FIG. 1, the portable terminal 100 includes a touch panel display. This touch panel display includes a proximity sensor, and can detect that the touch surface is directly touched. In addition, by using the proximity sensor, a space separated from the touch surface by a predetermined distance without being touched directly. It is possible to detect the user's finger located in A so-called hover can be detected. In addition, it is not restricted to using a proximity sensor, A finger in a hover state can be similarly detected by increasing the sensitivity of the touch panel.

  FIG. 2 is a block diagram showing a functional configuration of the mobile terminal 100. As shown in FIG. 2, the portable terminal 100 includes a CPU 101 (character generation unit), a RAM 102 (storage unit), a ROM 103, a wireless communication unit 104, a display control unit 105, a display unit 106 (touch panel display), and a touch control system 107. , A hover control system 108, a touch panel 109 (touch panel display), and a display data storage unit 110.

  The CPU 101 is a processor unit that performs integrated control of the mobile terminal 100 according to a program stored in the ROM 103, and performs, for example, input processing for receiving characters touched by the touch panel 109, conversion processing for received characters, and the like. In addition, application activation and execution, and wireless communication control using the wireless communication unit 104 are performed.

  The RAM 102 is a memory part that constitutes a work area for executing an application program.

  The ROM 103 is a part that stores a program for performing the basic operation of the mobile terminal 100.

  The wireless communication unit 104 is a part that is connected to a public mobile communication network or a wireless LAN. For example, in the mobile terminal 100, a mail application that is controlled by the CPU 101 is used by the user using the wireless communication unit 104. It is possible to send and receive e-mails etc. input by. In addition, it is also used for Web browsing and telephone calls.

  The display control unit 105 is a part that performs display control on the display unit 106. The display control unit 105 performs display control in accordance with control by the CPU 101, a touch control system 107 and a hover control system 108, which will be described later. In the present embodiment, display control is performed to superimpose a key selection screen or the like based on the position of the user's finger on the key input screen or the like.

  The display unit 106 is a part for displaying various information by the display control unit 105. For example, a key input screen / key selection screen for character input is displayed. In addition, the received mail and Web page are displayed.

  The touch control system 107 is a part that detects that a predetermined part of the touch panel 109 is touched by an input instruction part such as a user's finger or a touch pen, and detects the coordinates thereof, and performs control according to the coordinates. For example, the touch control system 107 detects coordinates touched on the touch panel 109 and notifies the CPU 101 of the detected coordinates. The CPU 101 executes processing for displaying a key input screen or key selection screen corresponding to the coordinates, and input processing for these input screens.

  The hover control system 108 determines whether or not an input instruction portion such as a user's finger or a touch pen is located in a hover input space (hover position) spaced from the touch surface of the touch panel 109 by a predetermined distance. This is the part that performs control. More specifically, the hover control system 108 touches the position of the user's finger (or touch pen, etc.) that is spaced apart from the touch surface of the touch panel 109 by a predetermined distance, and the user's finger at that position from that position. Control is performed based on the plane coordinates of the touch panel 109 when it is lowered vertically to the surface. That is, control is performed to detect how far the user's finger is away from the touch surface and at what coordinates with respect to the touch surface at that time, and notify the CPU 101 to that effect. The CPU 101 can perform display control of a key selection screen based on the position. Detailed processing based on the hover control system 108 and the CPU 101 will be described later.

  The touch panel 109 is a part that determines whether or not the touch surface is touched by an input instruction part such as a user's finger or a touch pen. In the present embodiment, the touch panel 109 and the display unit 106 constitute a touch panel display.

  The display data storage unit 110 is a part that stores display data to be displayed on the display unit 106. In this embodiment, a key input screen is stored as the display data, such as a QWERTY key input screen, a numeric keypad input screen, or a key input screen based on “Akasana”. In addition, a key selection screen for selecting characters such as hiragana characters in the “A” line such as “Aie no Eo” is stored in association with the hover position (XYZ coordinates) and the touch position (XY coordinates). .

  Next, switching of the key selection screen according to control by the touch control system 107, the hover control system 108, and the CPU 101 in the mobile terminal 100 configured as described above will be described.

  FIG. 3 is an explanatory diagram showing the positional relationship between the user's finger u and the distance from the touch surface of the touch panel 109. FIG. 4 is an explanatory diagram showing the transition of the key selection screen according to the relationship between the position of the user's finger u from the touch surface and the plane coordinates of the touch surface when the finger u is vertically lowered from the position. It is.

  FIG. 3 shows a state where the user's finger u moves with respect to the touch surface z4 from the reference surface z1 at a predetermined distance from the touch surface z4 via the reference surfaces z2 and z3. In FIG. 3, when a hover selection space is defined between the reference plane z1 and the reference plane z2 and a finger is detected between them, a key selection screen 11 that is a selection screen for hiragana is displayed. . Further, when a finger is detected between the reference plane z2 and the reference plane z3 as a hover input space, it is displayed on the key selection screen 11 according to the coordinates at that time. The input is made for Hiragana.

  The hover control system 108 detects the plane coordinates of the touch panel 109 when the finger u is positioned on the reference plane z1, and notifies the CPU 101 of this. The CPU 101 reads a key selection screen corresponding to the coordinates on the reference plane z1 from the display data storage unit 110, and instructs the display control unit 105 to display the key selection screen on the display unit 106.

  First, as a premise thereof, as shown in FIG. 4A, a key input screen 10 composed of a character string in the “A” level among the fifty-sounds “Akasana Hamaharawa” is displayed. That is, a so-called key input screen 10 is displayed that enables selection of hiragana including any consonant.

  When the finger u moves to the reference plane z1, a key selection screen 11 corresponding to the plane coordinates when the finger u moves is displayed. FIG. 4B shows the key input screen 10. Here, a key selection screen 11 in which the hiragana characters in the “ka” row can be selected is displayed in a superimposed manner. Here, a modification instruction key 12 for further modifying each hiragana is also displayed. Here, in addition to the muddy point addition key 12a, the punctuation point addition key 12b and the punctuation point addition key 12c indicating sentence breaks are listed as modification instructions. Furthermore, a continuous input key 12d for continuously inputting the same hiragana is also included. In addition, in the case of “ha” line, a key for adding a semi-voice point is included, and in the case of “ya” line, a key for making a roar, that is, for making hiragana lowercase, should be included. Can do. The same applies to the prompt sound (small “tsu”).

  When the finger u moves to the reference plane z2, a hiragana corresponding to the plane coordinates at the destination is selected. FIG. 4C shows the key input screen 10 and the key selection screen 11. Here, “ku” is selected, and the “ku” key is highlighted so that the selection can be understood.

  Thereafter, the finger u moves to the touch surface z4 via the reference surface z3. In the movement history, even if the finger u passes the reference plane z3, the hover control system 108 does not perform any detection processing. That is, when the finger u moves, the user's finger u is detected while moving from the reference surface z2 to the touch surface z4 via the reference surface z3 so as not to select a character that the user did not intend to select. It is configured not to process anything. This space has a role as a so-called non-selection space.

  Then, when the finger u moves to the touch surface z4, that is, when the finger u touches the touch panel 109, the selected hiragana is confirmed. Note that the hiragana to be determined differs depending on the plane coordinates on the touch surface finally touched. For example, when any of the modification instruction keys 12 is touched, a modification process is performed on the selected hiragana. In FIG. 4D, after “ku” is selected, the cloud point addition key 12a, which is one of the modification instruction keys 12, is touched, so that “gu” with the cloud point added is determined as the input character.

  In this manner, key input control based on detection control by the touch control system 107 and the hover control system 108 can be performed. In the present embodiment, the “modified character” includes a character to which a punctuation mark is added in addition to a character to which a cloud mark or the like is added. “Modify” includes adding punctuation marks and the like.

  Next, processing of the mobile terminal 100 will be described. FIG. 5 is a flowchart showing processing of the mobile terminal 100 of the present embodiment. First, when the user taps a character input field on the touch panel 109 (S101), the touch coordinates are detected by the touch panel control system 107 and notified to the CPU 101. Then, under the control of the CPU 101, the key input screen 10 is read from the display data storage unit 110, and the key input screen 10 is displayed on the display unit 106 (S102, see FIG. 4A).

  Next, it is detected by the hover control system 108 that the user's finger u has moved and is positioned on the reference plane z1, and the plane coordinates (XY coordinates) of the touch panel 109 at that position are detected by the hover control system 108. It is detected (S103). Then, the CPU 101 is notified of the position and coordinates detected by the hover control system 108. In the CPU 101, the key selection screen 11 according to the notified position and plane coordinates is read from the display data storage unit 110, and a display instruction is given to the display control unit 105. The display unit 106 displays the key selection screen 11 in accordance with the control (S104, see FIG. 4B).

  Here, when the user's finger u moves upward from the reference plane z1, that is, when the user's finger u cannot be detected by the hover control system 108 (S105: NO), the process returns to S102 and the key input is performed again. A screen 10 is displayed.

  On the other hand, the user's finger u is continuously detected (S105: NO), and the hover control system 108 detects that the finger u moves from the reference plane z1 to the reference plane z2, and the plane coordinates thereof are detected. (S106), the CPU 101 is notified of the position and coordinates, and characters according to the spatial position are selected as input candidates under the control of the CPU 101. Under the control of the CPU 101, the character is temporarily stored in the work area (RAM 102) for character input processing (S107), and the hiragana selected from the hiragana displayed on the key selection screen 11 is Then, it is displayed in reverse on the display unit 106 (S108, see FIG. 4C).

  Further, the touch control system 107 determines whether or not the user's finger u has moved to the touch surface z4, that is, whether or not the touch surface has been touched (S109). Here, the determination is made until the finger is touched or the finger is released (from the detection range).

  When the touch control system 107 determines that the finger u has touched the touch surface, the type of the touched key is further determined. That is, it is determined whether it is any one of the modification instruction keys 12 such as a muddy point addition key, a semi-middle point addition key, a phrase point addition key, a reading point addition key, a small addition key, and a continuous input key. That is, the touched coordinate is detected by the touch control system 107, and based on the detected coordinate, the CPU 101 determines whether any one of the modification instruction keys 12 has been selected (S110, see FIG. 4D). ).

  If the touch control system 107 and the CPU 101 determine that the touched key type is the modification instruction key 12 such as a cloud point, the CPU 101 generates a character combined with the temporarily stored hiragana. (S111). On the other hand, if the CPU 101 determines that the other hiragana part is touched, the hiragana touched is selected as an input character without using the hiragana temporarily stored in the work area, and confirmed. (S112).

  Then, the temporarily stored hiragana is deleted from the work area (S113), and the confirmed hiragana is displayed in the character input field on the display unit 106 (S114).

  Thus, the touch control system 107 and the hover control system 108 switch and display the key selection screen 11 based on the position of the user's finger u in the vertical direction with respect to the touch surface and the plane coordinates of the touch surface. Thus, key input can be performed with a simple operation.

  Next, variations of the key selection screen 11 for each line in the Japanese syllabary will be described. FIG. 6 is an explanatory diagram showing variations of the key selection screen 11. FIG. 6A shows the key selection screen 11 for the “A” line. As shown in the figure, as the modification instruction key 12, a lowercase letter conversion key, a cloud point addition key, a reading point addition key, and a continuous input key are shown. FIGS. 6B and 6C show the key selection screen 11 for the “ka” and “sa” lines, respectively. As shown in the figure, as the modification instruction key 12, a cloud point addition key, a phrase point addition key, a reading point addition key, and a continuous input key are shown.

  FIG. 6D shows the key selection screen 11 for the “ta” row. As shown in the figure, as the modification instruction key 12, a lowercase letter conversion key, a cloud point addition key, a phrase addition key, a reading addition key, and a continuous input key are shown.

  FIG. 6E shows the key selection screen 11 for the “NA” line. Here, as the modification instruction key 12, a punctuation mark addition key and a continuous input addition key are shown. FIG. 6F shows the key selection screen 11 for the “ha” line. Here, as the modification instruction key 12, a semi-turbid point addition key, a cloud point addition key, a phrase point addition key, a reading point addition key, and a continuous input key are shown.

  FIG. 6G shows the key selection screen 11 for the “ma” line. As in FIG. 6 (e), a punctuation mark addition key and a continuous input key are shown as the modification instruction keys 12. FIG. 6H shows the key selection screen 11 for the “ya” line. Similar to FIG. 6A, a lowercase conversion key, a phrase addition key, a reading addition key, and a continuous input key are shown as the modification instruction keys 12.

  FIGS. 6 (i) and 6 (j) show the key selection screen 11 for the “ra” row and the “wa” row. As in FIG. 6 (e), a punctuation mark addition key and a continuous input key are shown as the modification instruction keys 12.

  FIG. 6 (k) is a description of each of the modification instruction keys 12 used in FIG. 6 (a) to FIG. 6 (j). The addition key, semi-semi-dot addition key, reading-score addition key, and phrase-adding key indicate that a cloud point, semi-sound mark, reading point, and phrase-score are added to the selected character, respectively. In continuous input, as the character implies, tapping this key will input the selected character. Although not illustrated, the present invention is not limited to these modification instructions, and may include instructions for underlining, changing the color of characters, and writing characters in italics.

The above-described key input screen 10 and key selection screen 11 are examples when applied to hiragana. In the case of katakana, the key input screen and key selection screen replaced with katakana can be applied.
Furthermore, it can be applied to alphabets. In the case of the alphabet, since there is no relation between vowels such as hiragana and katakana and consonants, for example, groups for each predetermined character such as a to c and df can be created and assigned to each key. As modifier keys, uppercase letters, lowercase letters, periods, commas, etc. are conceivable. An example is shown in FIG.

  FIG. 7 is an explanatory diagram of a key input screen 10x, a key selection screen 11x, and a modification instruction key 12x when applied to the alphabet. FIG. 7A shows a key input screen 10x. Each key is grouped into A, C, D, F, etc., regardless of vowels and consonants. Here, when a key composed of ABC groups is tapped, a key selection screen 11x and a modification instruction key 12x shown in FIG. 7B are displayed. As described above, in any one of the key selection screens 11x, detection processing is performed by the hover control system 108. After that, when any of the modification instruction keys 12x is tapped on the touch surface, the modification instruction is performed. Modification processing according to the key 12x is performed.

  Next, functions and effects of the mobile terminal 100 of the present embodiment will be described. According to the mobile terminal 100 of the present embodiment, on the touch panel 109 constituting the touch panel display, one character is accepted by hover input, and thereafter a modification instruction for modifying one character is accepted by touch input. The touch control system 107 and the hover control system 108 detect and notify the CPU 101 of this, and the CPU 101 generates a modified character based on the one character and the modification instruction according to the notification, and displays the touch panel display. Unit 106 displays the generated modified character. Thereby, the modification process with respect to a character can be performed, without performing touch operation in multiple times. For example, the characters can be marked with a diacritic mark, made lowercase, or even punctuation marks can be shaken together. In addition, the modified character here includes a character to which a punctuation mark is added, in addition to a character to which a cloud point is added. Moreover, to modify includes adding punctuation marks or the like.

  Further, according to the mobile terminal 100 of the present embodiment, the CPU 101 temporarily stores in the work area one character received by hover input on the touch panel display (touch panel 109). When a modification instruction is received by touch input on the touch panel 109, the CPU 101 reads out one stored character and generates a modification character based on the one character and the modification instruction received by the touch input. Thereby, it is possible to perform a modification process on characters without performing a plurality of touch operations.

  In addition, according to the mobile terminal 100 of the present embodiment, it is below the hover input space (space between the reference surface z2 and the reference surface z3) and above the touch surface (touch surface z4) of the touch panel 109 (touch panel display). The hover control system 108 does not accept the detection of the user's finger u or the like (input instruction portion) located between That is, when the user's finger u, which is the input instruction portion, tries to move from the hover input space to the touch surface, the lower portion is moved from the hover input space so that other characters are not selected by mistake. However, it should not be detected. Thereby, an erroneous operation can be prevented.

  Further, according to the mobile terminal 100 of the present embodiment, the touch panel 109 is located in the hover selection space (the space between the reference plane z1 and the reference plane z2) that is a space above the hover input space. When this is detected, the display unit 106 can display a selection screen for selecting one character from a plurality of character selection candidates under the control of the CPU 101. This makes it possible to input various characters. That is, for example, each character in the “A” stage can be displayed as an input screen, and a selection screen for further selecting an arbitrary character, that is, a character associated with the selected character can be displayed.

  Further, according to the mobile terminal 100 of the present embodiment, it is possible to enable key input according to the coordinates on the touch panel 109 by displaying a key selection screen corresponding to the position of the user's finger u on the plane coordinates. it can.
