FIG.

Hereinafter, an information processing apparatus according to each embodiment of the present invention will be described with reference to the drawings. Specifically, a mobile phone will be described as an example of the information processing apparatus. In the following description, the same reference numerals are assigned to the same members. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.
[Embodiment 1]
<A. Appearance>
FIG. 1 is a perspective view of the mobile phone 1. With reference to FIG. 1, the mobile phone 1 includes an upper housing 101, a lower housing 102, and a hinge portion 103. The upper housing 101 and the lower housing 102 are connected by a hinge portion 103.

  The upper housing 101 includes a display 160 as a display unit. The lower housing 102 includes an electrostatic key 130 as an input unit.

  The electrostatic key 130 is an input device for receiving a user operation for inputting information to the mobile phone 1. The electrostatic key 130 includes a numeric keypad 300, an electrostatic sensor 350, and other operation keys such as a cross key. As will be described in detail later, the electrostatic sensor 350 is disposed on a substrate built in the lower housing 102.

  The electrostatic key 130 determines a press operation of a plurality of keys including the numeric keypad 300 and an input operation (hereinafter also referred to as “touch operation”) for a key that is not accompanied by pressing of the key. The input operation includes a flick operation. Hereinafter, the flick operation will be described as including a tap operation when inputting characters. The “tap operation” is an operation that does not involve pressing of a key, and refers to an operation in which the user releases a finger from the touched key without touching another key after touching the key with the finger or the like. .

  Further, the electrostatic key 130 can accept a flick operation while the key is pressed. In other words, not only by touching the key but also by pressing, a plurality of characters (for example, “A”, “I”, “U”, “E”, “O”) are displayed, and the finger is moved from this state. A user operation to play may be accepted. In this case, when the user selects one character from a plurality of characters, the user may simply flip his / her finger, and does not need to press another key adjacent to the pressed key in the direction in which the finger is played.

  By the way, the mobile phone 1 is configured to detect a touch operation using capacitance, but is not limited to this. The mobile phone 1 only needs to include a touch pad (touch sensor), and the touch pad may be a resistive film method, an optical method, an ultrasonic method, or the like.

  1 is a foldable type, it may be a flat type. Further, the information processing apparatus is not limited to the mobile phone 1, and may be, for example, a tablet terminal, a personal computer, a digital camera, an audio player, a smartphone, a wearable terminal, or the like.

<B. Electrostatic Key 130>
A specific structure of the electrostatic key 130 will be described later. Hereinafter, the surface of the lower housing 102 that faces the display surface of the display 160 when the upper housing 101 and the lower housing 102 are folded is referred to as a “main surface”.

  FIG. 7 is a cross-sectional view schematically showing the configuration of the electrostatic key 130. Referring to FIG. 7, each key 301, 302,... (See FIG. 2A) constituting numeric keypad 300 is mounted on electrostatic sensor 350 disposed on the main surface. Each key 301, 302,... Is composed of a hemispherical (dome-shaped) 391 having a hollow portion inside and a part of the film 392.

  The film 392 is provided on the side opposite to the electrostatic sensor 350 with respect to the member 391. On the film 392, numerical values (“0”, “1”, “2”, “3”, “4”... “9”), characters, symbols, and the like corresponding to the corresponding keys are printed.

  Each member 391 is deformed in a direction in which the top approaches the electrostatic sensor 350 when the user applies a predetermined force or more to the film 392 in the direction of the arrow 999 from the outside. Since the capacitance further changes due to the deformation as compared with the touch operation, the mobile phone 1 can detect the key press.

  Specifically, the electrostatic sensor 350 includes a plurality of sensor electrodes arranged in a matrix. Each key 301, 302,... Constituting the numeric keypad 300 is mounted on a plurality of sensor electrodes arranged in a matrix. As shown in the figure, since the keys 301, 302,... Constituting the numeric keypad 300 are physically separated at the position of the member 391, the user can operate the keys 301, 302,. it can. When the keys 301, 302,... Are operated, the capacitance of the corresponding sensor electrode changes. The mobile phone 1 can determine whether the user's operation is a “pressing operation” or a “touch operation” based on the change in capacitance.

  More specifically, the electrostatic key 130 removes noise in the detection signal from each sensor electrode of the electrostatic sensor 350 and outputs the detection signal. The detection signal from each sensor electrode includes a signal representing the amount of change in capacitance and the position of the sensor electrode on the matrix.

  In the first embodiment, the electrostatic sensor 350 is arranged under the numeric keypad 300, but the arrangement method of the electrostatic sensor 350 is not limited to this method. That is, the electrostatic sensor 350 may be disposed so as to overlap the numeric keypad 300. Therefore, the electrostatic sensor 350 may be disposed on the numeric keypad 300 in an overlapping manner.

<C. Example of operation>
FIG. 2 is a diagram for explaining a specific method of character input using a flick operation and a press operation. Specifically, FIG. 2 is a diagram for explaining a user operation when inputting a conversion candidate (specifically, “blue sky”) corresponding to hiragana “a” as an example. Note that the input conversion candidate is an example, and the present invention is not limited to this.

  Referring to FIG. 2, mobile phone 1 includes keys 301 to 312 constituting numeric keypad 300 and cross key 313. When the operation mode of the mobile phone 1 is changed to the character input mode based on the user operation, the mobile phone 1 displays characters input by the user operation with the finger 901 or the like on the display 160 as shown in the state (A). A character input area 610 is displayed.

  In the state (A), when the user performs a flick operation for inputting “A” to the key 301 of “1”, the mobile phone 1 changes the display content of the screen from the state (A) to the state (B). Transition to. In the state (B), the mobile phone 1 displays the hiragana “a” in the character input area 610 and displays a plurality of conversion candidates corresponding to “a” in the conversion candidate display area 620.

  That is, the mobile phone 1 displays on the display 160 the character selected by the flick operation with the finger 901 and a plurality of conversion candidates associated in advance with the selected character. Specifically, when the mobile phone 1 displays the characters selected by the flick operation and the plurality of conversion candidates on the display 160, the plurality of conversions are performed in a state where different numbers are associated with each of the plurality of conversion candidates. Display candidates. For example, conversion candidate “morning” is associated with No. 1, and conversion candidate “blue sky” is associated with No. 2.

  In the mobile phone 1, each of the plurality of conversion candidates is associated with a different key from among the plurality of keys. Specifically, the five conversion candidates are associated with different keys among the plurality of keys 301 to 305. For example, the first conversion candidate “morning” is associated with the key 301 representing “1”, and the second conversion candidate “blue sky” is associated with the key 302 representing “2”.

  As shown in the state (B), the mobile phone 1 causes the display 160 to display the selected character (that is, “A”) and the plurality of conversion candidates (specifically, five conversion candidates). When the electrostatic key 130 receives a pressing operation on any of the plurality of keys (specifically, the keys 301 to 305), the conversion candidate associated with the key that has received the pressing operation is input. Accept. Specifically, in the mobile phone 1, the electrostatic key 130 is the numeric keypad 300 (more precisely, the keys 301 to 309 and 311) with the selected character and the plurality of conversion candidates displayed on the display 160. When a pressing operation for any of the keys is received, an input of a conversion candidate associated with the same number as the key number that has received the pressing operation is received.

  For example, when the cellular phone 1 receives a pressing operation on the key 302 representing “2” in the state (B), the conversion candidate “blue sky” associated with the same number as the number of the key 302 (that is, “2”). "Is accepted. That is, the mobile phone 1 displays the conversion candidate “blue sky” in the character input area 610. Through the series of operations described above, the conversion candidate “blue sky” corresponding to “A” is input.

[Supplement]
(1) In the above operation example, a description has been given by taking as an example a configuration in which at least “blue sky” is displayed when “a” is input. However, the mobile phone 1 does not always display “blue sky” as a conversion candidate when only “a” (that is, one hiragana character) is input. For example, in one aspect, the mobile phone 1 often displays “blue sky” as a conversion candidate by inputting a plurality of characters (Hiragana).

  As described above, the mobile phone 1 may display the conversion candidate desired by the user when one hiragana character is input, or the conversion candidate desired by the user when a plurality of hiragana characters are continuously input. May be displayed. The latter configuration will be described below with a specific example.

  The user inputs “A” (that is, touches “1” key 301 and releases his / her finger), then touches “1” key 301 again and further flicks to input “O”. To do. The user touches the “3” key 303 and further flicks to input “so”. Through these user operations, the mobile phone 1 displays “blue sky” on the display 160 as a conversion candidate.

  In other words, when the user inputs a certain character (for example, “A”), the subsequent flick input is effective, and if “blue sky” is displayed as the second conversion candidate at this time, When the user touches the “2” key 302 and releases the finger, “ka” is input (that is, “red”, for example, “red”, “Akasaka”, etc. are displayed as conversion candidates). On the other hand, when the user presses the “2” key 302 after “A”, “blue sky” is selected.

  (2) In the above description, the operation example in which a plurality of conversion candidates are displayed has been described as an example. However, the present invention is not limited to this. In one aspect, one conversion candidate may be displayed. That is, the mobile phone 1 may be configured to display a plurality of conversion candidates.

<D. Summary>
(1) As described above, the mobile phone 1 includes the electrostatic key 130 having a plurality of keys and the display 160. The electrostatic key 130 determines, for each of the plurality of keys 301 to 312, a pressing operation of the keys 301 to 312 and an input operation to the keys 301 to 312 that are not accompanied by pressing of the keys 301 to 312.

  When the electrostatic key 130 accepts a flick operation as an input operation, the processor of the mobile phone 1 (specifically, a CPU to be described later) associates the character selected by the flick operation with the selected character in advance. The displayed plurality of conversion candidates are displayed on the display 160. Each of the plurality of conversion candidates is associated with a different key among the plurality of keys 301 to 312.

  In the state where the selected character and the plurality of conversion candidates are displayed on the display 160, the mobile phone 1 performs the pressing operation when the electrostatic key 130 receives a pressing operation on any of the plurality of keys. Accepts input of conversion candidates associated with the accepted key.

  According to the above configuration, the user of the mobile phone 1 can input conversion candidates by using the keys 301 to 312 used for flick input.

  (2) Specifically, the plurality of keys 301 to 312 are keys constituting the numeric keypad 300 as described above. When displaying the selected character and the plurality of conversion candidates on the display 160, the mobile phone 1 (specifically, a CPU described later) associates different numbers with each of the plurality of conversion candidates. The plurality of conversion candidates are displayed in a state. In the state where the selected character and the plurality of conversion candidates are displayed on the display 160, the mobile phone 1 receives a pressing operation on any of the keys constituting the numeric keypad when the electrostatic key 130 is displayed. An input of a conversion candidate associated with the same number as the key number for which the pressing operation has been received is received.

  According to the above configuration, the user can input conversion candidates by using the keys 301 to 312 constituting the numeric keypad 300.

  (3) More specifically, the mobile phone 1 (specifically, a CPU to be described in detail later) preliminarily sets a key that has received an input operation based on an input operation (touch operation) to any one of a plurality of keys. Each of the plurality of associated characters is displayed on the display 160 as an input candidate. When the mobile phone 1 receives a flick operation in a state where a plurality of input candidates are displayed, the mobile phone 1 selects the input candidate selected by the flick operation from the plurality of input candidates as a character to be converted ( For example, “a”) is displayed in the character input area 610 displayed on the display 160.

  In the state where the conversion target character and the plurality of conversion candidates are displayed on the display 160, the mobile phone 1 receives the pressing operation on any one of the plurality of keys and the conversion target character A conversion candidate (for example, “blue sky”) that has received the input instead of the character is displayed in the character input area 610.

<E. Control structure>
FIG. 3 is a flowchart for explaining the flow of processing in the mobile phone 1. Referring to FIG. 3, in step S <b> 2, mobile phone 1 causes display 160 to display a character selected by a flick operation and conversion candidates associated in advance with the selected character. In step S4, the mobile phone 1 determines whether or not a pressing operation on any of the keys constituting the numeric keypad has been accepted.

  If it is determined that it has not been accepted (NO in step S4), portable telephone 1 advances the process to step S4. If it is determined that it has been accepted (YES in step S4), in step S6, the mobile phone 1 determines whether or not there is a conversion candidate corresponding to the key for which the pressing operation has been accepted.

  If it is determined that there is a conversion candidate (YES in step S6), in step S8, the mobile phone 1 receives an input of the conversion candidate associated with the key for which the pressing operation has been received. If it is determined that there is no conversion candidate (NO in step S6), mobile phone 1 advances the process to step S4. For example, in the state (B) of FIG. 2, when the key 306 is pressed instead of the key 302, the mobile phone 1 advances the process to step S4.

<F. Hardware configuration>
FIG. 4 is a diagram for explaining a hardware configuration of the mobile phone 1. Referring to FIG. 4, mobile phone 1 includes a central processing unit (CPU) 110, a memory 120, an electrostatic key 130, an electrostatic key driver 140, a display driver 150, and a display 160.

  As described above, the electrostatic key 130 includes at least a numeric keypad 300 including a plurality of keys 301, 302, 303,... And an electrostatic sensor 350. The memory 120 is typically a non-volatile memory such as a flash memory. The memory 120 stores an OS (Operating system), a plurality of application programs including Kanji conversion software (Japanese input system), and various data.

  The electrostatic key driver 140 is a driver for the electrostatic key 130. The electrostatic key driver 140 receives touch information from the electrostatic sensor 350. When the user performs a flick operation, the electrostatic sensor 350 receives flick operation information (more precisely, information on a plurality of coordinate values) from the electrostatic sensor 350 as touch information.

  Further, the electrostatic key driver 140 acquires key operation information by the user from each key 301, 302, 303,... Constituting the numeric keypad 300 based on a pressing operation by the user. Specifically, the electrostatic key driver 140 receives information for specifying the depressed key from the key. The electrostatic key driver 140 sends the touch information and the key operation information to the CPU 110.

The CPU 110 displays various information on the display via the display driver 150. As an example, the CPU 110 causes the display 160 to display the character input area 610, the conversion candidate display area 620, and the like shown in FIG. 2 at predetermined positions. In addition, the CPU 110 performs control to display the input candidates selected by the flick operation and the conversion candidates selected by the subsequent pressing operation in the character input area 610.

Is displayed on the display 160 (state (A)). Specifically, when the user performs a flick operation for inputting “a” to the key 301 of “1”, the mobile phone 1A displays the hiragana “a” in the character input area 610, A plurality of conversion candidates corresponding to “A” are displayed in the conversion candidate display area 620. Specifically, when the mobile phone 1A displays the selected character and the plurality of conversion candidates on the display 160, the first conversion candidate (in the state (A), among the plurality of conversion candidates, In order to indicate that “morning”) is selected, the first conversion candidate is set to a focused display mode.

  Note that the display example of the conversion candidates displayed in the conversion candidate display area 620 is an example, and the conversion candidates may not necessarily be displayed in order from the upper left to the lower right as shown in FIG. For example, the conversion candidates may be displayed in association with the same arrangement as the arrangement of the key 301, the key 302, and the like.

  In the state (A), the portable telephone 1A gives the function of the cross key 313 to the four keys 302, 304, 306, and 308. Specifically, an input realized by the cross key 313 for changing the conversion candidate in the selected state to another conversion candidate is realized by pressing the four keys 302, 304, 306, and 308.

  For example, in the state (A), when the user presses the key 304, the mobile phone 1A performs a focus movement process associated with the key 304. Specifically, when the user presses the key 304 located on the left side of the center key 305 of the nine keys 301 to 309, the mobile phone 1A performs the same focus processing as when the left side portion of the cross key 313 is pressed.

That is, the mobile phone 1A changes the screen from the state where the conversion candidate “morning” is selected to the state where the conversion candidate “warm” is selected.

  In the state (A), when the user presses the key 302, the mobile phone 1 </ b> A performs a focus movement process associated with the key 302. Specifically, when the user presses the key 302 located above the center key 305, the mobile phone 1A performs the same focus processing as when the upper portion of the cross key 313 is pressed. As a result, as shown in the state (C), the fifth conversion candidate “warm” is focused. That is, the mobile phone 1A changes the screen from the state where the conversion candidate “morning” is selected to the state where the conversion candidate “warm” is selected.

  In the state (A), when the user presses the key 308, the mobile phone 1 </ b> A performs a focus movement process associated with the key 308. Specifically, when the user presses a key 308 located below the center key 305, the mobile phone 1A performs the same focus processing as when the lower part of the cross key 313 is pressed. As a result, as shown in the state (D), the third conversion candidate “morning” is in focus. That is, the mobile phone 1A changes the screen from the state where the conversion candidate “morning” is selected to the state where the conversion candidate “morning” is selected.

  In the state (A), when the user presses the key 306, the mobile phone 1 </ b> A performs a focus movement process associated with the key 306. Specifically, when the user presses the key 306 located on the right side of the center key 305, the mobile phone 1A performs the same focus processing as when the right side portion of the cross key 313 is pressed. As a result, as shown in the state (E), the second conversion candidate “blue sky” is focused. That is, the mobile phone 1A changes the screen from the state where the conversion candidate “morning” is selected to the state where the conversion candidate “blue sky” is selected.

  The “5” key 305 has a function as a confirmation key. Specifically, when the user presses the key 305 in a state where any one of the plurality of conversion candidates is focused, the focused conversion candidate is input to the character input area 610.

  For example, when the user presses the “5” key 305 in the state (E), the conversion candidate “blue sky” in focus is input to the character input area 610 (state (F)). If the user presses the key 305 in the state (B), the conversion candidate “warm” in focus is input to the character input area 610. In other words, the mobile phone 1 is in the state where the focus is applied to the second conversion candidate (for example, “blue sky”, “warm”) among the plurality of conversion candidates by the focus movement process. When 130 receives a pressing operation on a predetermined key 305 among the plurality of keys, the second conversion candidate is input.

  Note that the cellular phone 1 </ b> A accepts pressing operations to the keys 302, 304, 306, and 308 until receiving a pressing operation of the key 305 from the user. That is, the mobile phone 1A accepts a pressing operation for moving the focus. For example, when the user presses the key 302 in the state (C), the mobile phone 1A performs the focus movement process associated with the key 302, and the conversion candidate “warm” is selected. The screen changes to a state where the conversion candidate “morning” is selected.

  In the above description, the function as the confirmation key is given to the key 305. However, the present invention is not limited to this. For example, the keys 301, 303, 307, and 309 to 312 may be given a function as a confirmation key. Alternatively, a function as a confirmation key may be given to a plurality of keys 301, 303, 305, 307, and 309 to 312.
