The touch panels 110 and 120 are visible.

<Calibration screen>
Next, a calibration screen displayed on the mobile phone 100 will be described.
FIG. 2 is a diagram illustrating a display example of the calibration screen G1.
This calibration screen G1 is displayed on the mobile phone 100 when the operation of the mobile phone 100 is started or when the mobile phone 100 receives a predetermined user operation.

The calibration screen G1 includes a software key D1 and a character string D5, and the mobile phone 100 assumes that the open / close state of the mobile phone 100 is “closed” and the orientation of the housing is “vertical”. In this case, the calibration screen G1 is displayed so that the user can visually recognize it.
Here, the software key D1 particularly includes a plurality of keys representing different alphabetic characters.

In the figure, each range indicated by a rectangle represented by a solid line in the software key D1 indicates the range of each key, and is displayed so that the user can visually recognize the range of each key. .
In the following description, it is assumed that when the user touches a range of each key with a finger or the like, touching the key or selecting a key.

The character string D5 is a character string (natural sentence) configured to include all 26 letters of the alphabet, so-called pangram.
When the calibration screen G1 is displayed, the user of the mobile phone 100 sequentially selects keys representing each character constituting the character string D5 included in this screen.
FIG. 3 shows a state in which the user operates the keys representing the characters constituting the character string D5 displayed on the touch panel 110 in FIG. 2 in order.

In the figure, the portion of the character corresponding to the key that the user has already touched with a finger or the like is shown in bold with an underline (see character string D5 ′). That is, FIG. 3 shows the user in order for each key (“T”, “h”, “e”, “” (space), “q”, “u”, “i”) representing “The qui”. Shows a state immediately after touching a finger or the like.
When the user brings a finger or the like into contact with the key, the mobile phone 100 calculates and stores the relative position of the contact location with respect to the key.

The relative position calculated for each key is, for example, a feature of user input such that when a certain key is selected, the contact location is shifted upward from the reference position of the key (hereinafter referred to as the center). It will be reflected.
Since the character string D5 is configured to include all 26 letters of the alphabet as described above, the mobile phone 100 calculates and stores the relative position with respect to each key of the 26 letters of the alphabet. become.

<Data>
Hereinafter, data used by the mobile phone 100 will be described with reference to FIG.
FIG. 8 is a diagram showing a data configuration and example contents of the area information table 10.
As shown in the figure, the area information table 10 corresponds to the open / closed state 11, the casing orientation 12, the key ID 13, the panel ID 14, the upper left coordinate value 15, the lower right coordinate value 16, the average deviation amount 17, and the difference value 18. It is information that is attached.

It should be noted that x1 to x7, x11 to x24, x30 to x33, y1 to y7, y11 to y24, and y30 to y33 shown in the figure represent specific numerical values.
Here, the open / close state 11 is information indicating whether the mobile phone 100 is in an open state or a closed state, and the housing direction 12 is information indicating whether each housing of the mobile phone 100 is in a vertical orientation or a horizontal orientation.
The key ID 13 is key identification information. In this example, as the key ID of each key constituting the software key, a number incremented by 1 in the arrangement order is used.

That is, as shown in FIGS. 2, 4 to 6, the key ID of the key (Q key) arranged at the upper left is “1”, and the key ID of the key (P key) arranged at the rightmost position in the same row. Is “10”, the key ID of the key (A key) arranged at the leftmost of the next line is “11”, and the key ID of the key (enter key) arranged at the lower right is “35”.
The panel ID 14 is identification information of the touch panel on which the key indicated by the corresponding key ID is arranged. In this example, the panel ID of the touch panel 110 is “1”, and the panel ID of the touch panel 120 is “2”. It is supposed to be.

The upper left coordinate value 15 is the coordinate value of the upper left vertex of the key range (rectangular region) indicated by the corresponding key ID, and the lower right coordinate value 16 is the coordinate value of the lower right vertex of the key range.
Note that the upper left coordinate value 15 and the lower right coordinate value 16 are registered in advance by the manufacturer of the mobile phone 100.
Moreover, the average deviation | shift amount 17 is an average value of the deviation | shift amount about each key in the use condition of a corresponding mobile telephone.

Here, the amount of deviation of a key refers to the amount of deviation of the contact location when the user touches the key with a finger or the like with respect to the center of the key.
The difference value 18 is a value obtained by subtracting the corresponding average deviation amount from the deviation amount for the key indicated by the corresponding key ID in the usage state of the corresponding mobile phone.
In the figure, for example, the upper left coordinate value of the range of the key (Q key) with the key ID “1” when the open / closed state is “closed” and the orientation of the housing is “vertical” is “(x11 , y11) ”, the lower right coordinate value is“ (x12, y12) ”, the average deviation amount is“ (x30, y39) ”, and the difference value is“ (x1, y1) ”. Yes.

Here, regarding the relationship between the upper left coordinate value and the lower right coordinate value of each key, the average deviation amount, and the difference value, the opening / closing state of the mobile phone 100 is “closed” and the orientation of the casing is “vertical” The Q key will be described as an example.
FIG. 9 is a diagram for explaining the relationship among the upper left coordinate value and lower right coordinate value of the Q key, the average deviation amount, and the difference value.

In the figure, only the software key D1 of the calibration screen G1 displayed when the open / close state of the mobile phone 100 is “closed” and the orientation of the housing is “vertical” is shown. The case and the like are omitted.
Here, the contact location P1 indicates a position corresponding to the coordinate value received by the receiving unit 150 from the input unit 112 when the user touches the Q key with a finger or the like on the calibration screen G1.

The contact point P1 with respect to the center ((x11 + x12) / 2, (y11 + y12) / 2) of the range of the Q key indicated by the rectangular area specified by the upper left coordinate value (x11, y11) and the lower right coordinate value (x12, y12) Relative position (x10− (x11 + x12) / 2, y10− (y11 + y12) / 2) is the shift amount of the Q key.
In this calibration screen G1, the touch of the user's finger or the like to keys representing other alphabetic characters (W key to M key) is accepted, the amount of deviation is also calculated, and the deviation of all keys representing 26 letters of the alphabet is calculated. The average value (average deviation amount) is calculated. In FIG. 8, for the sake of simplification of description, this average deviation amount is described as (x30, y30).

Further, a value obtained by subtracting the average deviation amount from the calculated Q key slip amount (x10− (x11 + x12) / 2−x30, y10− (y11 + y12) / 2−y30) is a difference value. In FIG. 8, this difference value is described as (x1, y1) in order to simplify the description.
<Operation>
Next, the operation of the mobile phone 100 having the above configuration will be described with reference to FIGS.

<Relative position calculation process>
FIG. 10 is a flowchart showing relative position calculation processing by the control unit 156 of the mobile phone 100.
The relative position calculation process shown in the figure is started when the mobile phone 100 starts operation and when a predetermined user operation is received.

First, the control unit 156 initializes a flag indicating the usage state of the mobile phone 100 to “1” (step S1).
Hereinafter, when the flag is “1”, it is assumed that the open / close state of the mobile phone 100 is “closed” and the orientation of the housing is “vertical”. Further, when the flag is “2”, the open / close state is “closed” and the orientation of the housing is “horizontal”, and when the flag is “3”, the open / close state is “ If the flag is “4”, the open / closed state is “closed” and the case orientation is “horizontal”. Each shall be shown.

The display control unit 154 displays a screen corresponding to the content of the flag on the display unit 111 or each display unit (111, 121) (step S2).
In the following description, it is assumed that the screens corresponding to the flags “1” to “4” are the calibration screen G1 to the calibration screen G4 (see FIGS. 2 and 4 to 6).
When the display control unit 154 displays the calibration screen according to the flag, the use state (opening / closing state and orientation of the housing) of the mobile phone 100 indicated by the flag in the area information table 10 of the storage unit 140 is displayed. Each key is displayed at a position specified by the upper left coordinate value and the lower right coordinate value of each key associated with.

For example, when the flag is “1” and the calibration screen G1 is displayed on the display unit 111, the rectangle indicating the range of the Q key has the coordinate value of the upper left vertex (x11, y11) and the lower right corner. It is displayed at a position where the coordinate value of the vertex is (x12, y12).
Note that the display control unit 154 also displays the range of each key at a position specified based on the area information table 10 when displaying the calibration screens G2 to G4, as in the case of displaying the calibration screen G1. A rectangle indicating is displayed.

Subsequently, the state specifying unit 152 specifies the actual use state (open / close state and orientation of the housing) of the mobile phone 100 based on the signals output from the open / close detection sensor 130 and the acceleration sensor 131, and the flag is set. It is determined whether or not it matches the usage state shown (step S3), and while not matching (step S3: NO), the process of step S3 is repeatedly executed.
When the actual usage state of the mobile phone 100 matches the usage state indicated by the flag (step S3: YES), the calculation unit 151 shifts all the keys representing each character constituting the character string D5. It is determined whether or not the calculation has been completed (step S4).

When the calculation of each deviation amount is not completed (step S4: NO), the calculation unit 151 selects the key with the smallest key ID among the keys for which the calculation of the deviation amount is not completed. Hereinafter, the selected key is referred to as “target key”.
Further, the receiving unit 150 determines whether or not the user has touched one of the touch panels with a finger or the like based on whether or not the coordinate value has been received from any of the input units (step S5).

When the coordinate value is not received from any input unit, the receiving unit 150 determines that the user does not touch the finger or the like (step S5: NO), and executes the process of step S5 again.
When the coordinate value is received from any of the input units, the reception unit 150 determines that the user has touched the finger or the like (step S5: YES), and the calculation unit 151 determines the coordinates of the center of the target key. A deviation amount of the received coordinate value, that is, the coordinate value of the contact point with respect to the value is calculated (step S6).

  When the process of step S6 is completed, the calculation unit 151 performs the process from step S4 again, and completes the calculation of the deviation amounts for all the keys representing each character constituting the character string D5 (step S4: YES), an average value (average deviation amount) of the calculated deviation amounts is calculated, and is registered in the area information table 10 of the storage unit 140 in association with the use state indicated by the flag (step S7).

Further, the calculation unit 151 calculates a value (difference value) obtained by subtracting the average shift amount from the shift amount calculated for the key for all keys representing each character constituting the calculated character string D5, and the flag indicates In association with the use state, the difference value of the key is registered in the area information table 10 of the storage unit 140 (step S8).
Further, the calculation unit 151 determines whether or not the flag is “4” (step S9).

  When the flag is “4” (step S9: YES), the control unit 156 ends the relative position calculation process. When the flag is not “4” (step S9: NO), the control unit 156 sets the flag value. The number is incremented by 1 (step S10), and the process is repeated from step S2. That is, the difference value and the average deviation amount are calculated for all keys representing each character constituting the character string D5 in the unprocessed usage state of the mobile phone 100.

<Specific processing>
FIG. 11 is a flowchart showing key specifying processing by the control unit 156 of the mobile phone 100.
At the time of starting the following description, the process execution unit 155 of the mobile phone 100 executes an application (in this example, a mail application) that performs input using a software key, for example, as shown in FIG. It shall be.

As shown in FIG. 11, the state specifying unit 152 of the control unit 156 determines the usage state (open / close state and orientation of the housing) of the mobile phone 100 based on the signals output from the open / close detection sensor 130 and the acceleration sensor 131. Specify (step S11).
The receiving unit 150 determines whether or not the user has touched one of the touch panels with a finger or the like based on whether or not the coordinate value has been received from any of the input units (step S12).

If no coordinate value is received from any input unit, the receiving unit 150 determines that the user has not touched the finger or the like (step S12: NO), and executes the process of step S12 again.
When the coordinate value is received from any of the input units, the receiving unit 150 determines that the user has touched the finger or the like (step S12: YES), and the key specifying unit 153 selects the displayed software key. It is determined whether or not the processing of step S14 described below has been performed for all the constituent keys (step S13).

When the process for all the keys is completed (step S13: YES), the control unit 156 performs the process from step S11 again.
If processing for all keys has not been completed (step S13: NO), the key specifying unit 153 selects a key (target key) having the smallest key ID from among unprocessed keys. The average deviation amount associated with the use state specified in step S11, the difference value of the target key, the upper left coordinate value, and the lower right coordinate value are acquired from the area information table 10 of the storage unit 140.

In the above-described relative position calculation process (see FIG. 10), the difference value is not calculated for the keys other than the keys representing the characters (26 alphabets) constituting the character string D5 among the software keys. Difference values for keys other than the keys representing the 26 letters of the alphabet are not registered in the area information table 10.
Therefore, when the difference value of the target key is not registered in the area information table 10, the key specifying unit 153 performs the following processing assuming that the difference value is “0”.

The key specifying unit 153 calculates the coordinate value of the corrected location by subtracting the acquired average deviation amount and difference value from the coordinate value of the contact location received in Step S12 (Step S14), and the calculated coordinate value of the corrected location. Is included in the range of the target key (rectangular region specified by the acquired upper left coordinate value and lower right coordinate value) (step S15).
If the coordinate value of the correction location is not included in the range of the target key (step S15: NO), the key specifying unit 153 performs the processing from step S13 again, and the coordinate value of the correction location is included in the range of the target key. If it is determined (step S15: YES), the key specifying unit 153 specifies the target key as a user operation target (step S16).

The process execution unit 155 performs processing with the key that is the target of the user operation as an input, and the control unit 156 performs processing from step S11 again.
≪Modification≫
In the above-described embodiment, a case has been described in which the key specifying unit 153 of the mobile phone 100 specifies the key to be operated by the user using the shift amount (average shift amount and difference value) for each key.

Below, the case where the key used as a user operation target is specified using the correction range which correct | amended the range of each key instead of the said deviation | shift amount is demonstrated.
The mobile phone according to this modification (hereinafter also referred to as “modified mobile phone”) is obtained by slightly changing the function of the key specifying unit 153 of the mobile phone 100 according to the embodiment and the data configuration of the area information table 10. is there. Therefore, here, the description will focus on the changed portion.

<Data>
First, data used by the modified mobile phone will be described with reference to FIG.
FIG. 13 is a diagram showing a data configuration and example contents of the area information table 20.
As shown in the figure, the area information table 20 includes an open / closed state 11, a casing orientation 12, a key ID 13, a panel ID 14, an upper left coordinate value 15, a lower right coordinate value 16, a corrected upper left coordinate value 21, and a corrected lower right coordinate. It is information configured in association with the value 22.

As described in the embodiment, x1 to x7, x11 to x24, x30 to x33, x41 to x53, y1 to y7, y11 to y24, y30 to y33, y41 to y53 shown in FIG. It shall represent a specific numerical value.
The area information table 20 includes the corrected upper left coordinate value 21 and the corrected lower right coordinate value 22 instead of the average deviation amount 17 and the difference value 18 of the area information table 10 according to the embodiment. Is different.

Show.

<Operation>
Next, the operation of the modified mobile phone will be described.
<Deformation relative position calculation process>
First, a relative position calculation process (hereinafter referred to as “deformed relative position calculation process”) by a control unit (hereinafter referred to as “deformation control unit”) of a modified mobile phone will be described with reference to FIG.

FIG. 14 is a flowchart showing a deformation relative position calculation process performed by the deformation control unit of the modified mobile phone.
As shown in the figure, the deformation relative position calculation process includes step S20 instead of steps S7 and S8 of the relative position calculation process shown in FIG. 10 described in the embodiment. It is different from the calculation process.

Hereinafter, the process of step S20 will be mainly described.
The deformation control unit performs the processes of steps S1 to S6 in the same manner as the control unit 156 according to the embodiment.
That is, the deformation control unit performs a flag initialization process (step S1), the display control unit 154 performs a screen display control process according to the contents of the flag (step S2), and the state identification unit 152 It is determined whether or not the usage state of the mobile phone 100 matches the usage state indicated by the flag (step S3).

When the actual use state of the mobile phone 100 matches the use state indicated by the flag (step S3: YES), the calculation unit 151 calculates the deviation amount for all the keys representing each character constituting the character string D5. A process for determining whether or not the calculation is completed is performed (step S4).
When the calculation of each deviation amount is not completed (step S4: NO), the reception unit 150 performs a determination process as to whether or not the user has touched one of the touch panels with a finger or the like (step S5), and the user If it is determined that the finger or the like has been touched (step S5: YES), the calculation unit 151 performs a calculation process of the deviation amount of the coordinate value of the contact location with respect to the coordinate value of the center of the target key (step S6), and again. Processing is performed from step S4.

When the calculation of the shift amount for all the keys representing each character constituting the character string D5 is completed (step S4: YES), the key specifying unit of the deformation control unit (hereinafter referred to as “deformed key specifying unit”) The corrected upper left coordinate value and the corrected lower right coordinate value for each key constituting the software key are calculated (step S20).
Here, for each key representing 26 letters of the alphabet, a value obtained by adding the shift amount for the key calculated in step S6 to the range of the key (upper left coordinate value and upper right coordinate value) is the corrected upper left coordinate of the key. The value and the corrected lower right coordinate value are registered in the area information table 20 of the storage unit 140 in association with the use state indicated by the flag.

  Similarly to step S7 in FIG. 10, the average deviation amount is calculated, and among the keys constituting the software key, for the keys other than the keys representing the 26 letters of the alphabet, the key range (upper left coordinate value). And the value obtained by adding the average deviation amount to the upper left coordinate value and the corrected lower right coordinate value of the key, and are registered in the area information table 20 of the storage unit 140 in association with the usage state indicated by the flag. .

Subsequently, the calculation unit 151 performs a flag value determination process (step S9). When the flag is “4” (step S9: YES), the deformation control unit ends the deformation relative position calculation process, When the flag is not “4” (step S9: NO), the value of the flag is incremented by 1 (step S10), and the processing is performed again from step S2.
<Transformation key identification process>
Next, a key specifying process (hereinafter referred to as “deformed key specifying process”) by the deformation control unit of the modified mobile phone will be described with reference to FIG.

FIG. 15 is a flowchart showing the deformation key specifying process by the deformation control unit of the modified mobile phone.
As shown in FIG. 11, the modified key specifying process includes steps S21 to S25 in place of steps S13 to S16 of the key specifying process shown in FIG. 11 described in the embodiment. It is different from processing.

Hereinafter, the process of steps S21 to S25 will be mainly described.
The deformation control unit performs the processes of steps S11 and S12 as with the control unit 156 according to the embodiment.
That is, the state specifying unit 152 of the deformation control unit performs processing for specifying the usage state of the deformed mobile phone (step S11), and the receiving unit 150 determines whether or not the user has touched one of the touch panels with a finger or the like. Processing is performed (step S12).

When the reception unit 150 determines that the user has touched a finger or the like (step S12: YES), the transformation key specifying unit performs step S22 described below for all keys constituting the displayed software key. It is determined whether or not processing has been performed (step S21).
When the processes for all the keys have not been completed (step S21: NO), the deformed key specifying unit selects the key (target key) having the smallest key ID from the unprocessed keys, and step S11. The corrected upper left coordinate value and the corrected lower right coordinate value for the target key associated with the use state specified in (2) are acquired from the area information table 20 of the storage unit 140.

Further, the deformation key specifying unit determines that the coordinate value of the contact location received by the receiving unit 150 in step S12 is a range after correction of the target key (rectangular region specified by the acquired corrected upper left coordinate value and corrected lower right coordinate value). ) Is included (step S22), and the process of step S21 is performed again.
When the process for all the keys is completed (step S21: YES), in step S22, the transformation key specifying unit determines that the coordinate value of the contact location received by the receiving unit 150 in step S12 is the value after the correction of the target key. The number of target keys determined to be included in the range is determined (step S23).

When the number of corresponding target keys is “0” (step S23: 0), the deformation control unit performs the process from step S11 again without performing any process.
If the number of corresponding target keys is one (step S23: 1), this target key is specified as the target of user operation (step S24), and the number of corresponding target keys is two. In the case of the above (step S23: 2 or more), one target key is selected from the corresponding target keys, the selected target key is specified as a user operation target (step S25), and the deformation control unit The process is performed again from step S11.

In step S25, for example, the key with the smallest key ID is selected from the corresponding target keys.
<Supplement>
The mobile terminal according to the present invention has been described above based on the embodiment and the modification. However, the mobile terminal can be modified as follows, and the present invention is as described in the above-described embodiment and modification. Of course, the mobile phone is not limited to this.

  (1) In the modified example, in the modified key specifying process (see FIG. 15), when there are a plurality of keys whose contact locations are included in the correction range (step S23: 2 or more), among the plurality of target keys, It has been described that the key with the smallest key ID is selected as the user operation target (step S25). However, the method of selecting one key from a plurality of corresponding target keys is not limited to this.

Here, when there are a plurality of keys whose contact locations are included in the correction range, the correction ranges of the plurality of keys overlap.
FIG. 16 is a diagram for explaining a method of specifying the operation target key when the correction ranges of a plurality of keys overlap.
For example, FIG. 16A shows a case where an overlapping range A3 exists between the correction range A1 and the correction range A2 of two keys, and the user's contact point P2 is included in the overlapping range A3.

In FIG. 16A, the correction range A1 is indicated by a dotted line, and the correction range A2 is indicated by a one-dot chain line.
When the two key ranges overlap as shown in FIG. 16A, the correction ranges A1 and A2 are changed to the correction ranges A11 and A21 as shown in FIG. You may make it select the object key corresponding to the corrected correction range (correction range A11 in the figure) including the contact location P2.

Here, the corrected correction range A11 is composed of a range A31 adjacent to the correction range A1 of two ranges (A31 and A32) obtained by equally dividing the overlapping range A3, and the correction range A1. is there.
The changed correction range A21 is composed of a correction range A2 and a correction range A2 adjacent to the correction range A2 of two rectangular ranges (A31 and A32) obtained by equally dividing the overlapping range A3. is there.

For example, FIG. 16C shows a case where an overlapping range A6 exists between the correction range A4 and the correction range A5 of the two keys, and the user's contact point P3 is included in the overlapping range A6. ing.
In FIG. 16C, the correction range A4 is indicated by a dotted line, and the correction range A5 is indicated by a one-dot chain line.

When the correction ranges of the two keys are shifted and overlapped as shown in FIG. 16C, the correction ranges A4 and A5 are replaced with a correction range A41 having a trapezoidal shape as shown in FIG. The target key corresponding to the corrected correction range (the correction range A41 in the figure) including the user contact point P3 may be selected.
Here, the corrected correction range A41 includes a correction range A4 and a correction range A4 adjacent to the correction range A4 of two triangular ranges (A61 and A62) obtained by equally dividing the overlapping range A6. Is.

The changed correction range A51 is composed of a correction range A5 and a correction range A5 adjacent to the correction range A5 of two triangular ranges (A61 and A62) obtained by equally dividing the overlapping range A3. It is.
(2) In the modified example, in the modified key specifying process (see FIG. 15), it is determined whether or not the contact location is included in the correction range of the key for all keys (steps S21 and S22). In the above description, the operation target is specified according to the number of keys included in the correction range (steps S23 to S25). However, without determining whether or not the touch location is included in the correction range of the key for all the keys, the key that is determined first when the touch location is included in the correction range is specified as the operation target. Also good.

  That is, if all the keys have not been processed in step S21 (step S21: NO), the process proceeds to step S22, and if it is determined that the contact location is included in the correction range of the key, step S24 is performed. The process is performed, and the process is performed again from step S11. On the other hand, when it is determined in step S21 that all the keys have been processed (step S21: YES), the process is performed again from step S11.

(3) In the embodiment, in the key specifying process (see FIG. 11), the first determined key is determined as the operation target when the corrected location where the contact location such as the user's finger is corrected is included in the range. Although described as a thing (step S15, S16), you may make it pinpoint an operation target by methods other than this.
For example, among the keys, the key having the shortest distance between the center of the key and the correction location may be specified as the operation target.

Similarly, in the modified example and the method for specifying the operation target key described in the modification of (1), the center of the corrected range of the key, the contact location such as the user's finger, The key having the shortest distance may be specified as the operation target.
(4) In the modification, as shown in the area information table 20, the correction location (corrected upper-left coordinate value and corrected lower-right coordinate value) for each key has been described in advance. The area information table 10 described above may be used, and when the user touches the touch panel with a finger or the like to perform an operation, a correction location for each key may be calculated.

  (5) In the embodiment, it has been described that the user inputs a character string D5 including 26 alphabetic characters and calculates the relative position. However, the present invention is not limited to this. For example, a character string including 50 hiragana characters is given to the user. You may make it input. The character string including 50 hiragana characters is preferably a natural sentence like the character string D5. As an example, it is possible to use a song.

In the embodiment, the software key has been described as including each key representing 26 letters of the alphabet. However, each key representing 50 hiragana characters may be included.
In addition to letters such as alphabets and hiragana characters, software keys can include numbers, symbols, and the like, and can also include shift keys, space keys, return keys, function keys, numeric keys, direction keys, and the like. .

(6) The process of steps S14 and S15 of the key specifying process (see FIG. 11) described in the embodiment and the process of step S22 of the modified key specifying process (see FIG. 15) described in the modified example are software keys. It has been described that it is performed for all the constituent keys (see step S13 in FIG. 11 and step S21 in FIG. 15).
However, when the user's finger or the like is touched, in the area information table (10 or 20), the key range (upper left coordinate value and the associated with the actual use state of the mobile phone 100 at that time) The rectangular range specified by the lower right coordinate value) specifies a key that is within a certain range from the user's contact location (coordinate value), and the above processing (the processing of steps S14 and S15, or the step only for the specified key) The processing of S21 may be performed.

(7) The mobile phone according to the embodiment and the modification displays each calibration screen (G1 to G4), and the user configures each character constituting the character string D5 displayed on each calibration screen. It has been described that the relative position of each key in each use state of the mobile phone is calculated by operating the key to be expressed.
However, a part of the calibration screens (G1 to G4) is displayed, and a key representing each character constituting the character string D5 displayed on the calibration screen is displayed to the user. You may make it operate.

That is, for some of the usage states of the mobile phone, the relative position for each key is calculated based on the user operation, and for the other usage states, each of the usage states calculated based on the user operation is calculated. You may make it calculate based on the relative position (henceforth "the directly calculated relative position") about a key.
For example, the calibration screen G1 is displayed, and the user operates the keys representing the characters constituting the character string D5, so that the open / close state of the mobile phone 100 is “closed” and the casing orientation is “vertical”. ”May be directly calculated, and the relative position for each key in the other use state may be calculated based on the directly calculated relative position.

  The calculation of the relative position for each key in other usage states is performed by, for example, the size of each key on the calibration screen (G1 in the above example) displayed when directly calculating the relative position for each key. It may be determined to be proportional to the ratio between the vertical and horizontal sizes of each key on the other calibration screens (G2 to G4 in the above example).

  For example, the vertical size of the Q key on the calibration screen G1 is “a0”, the horizontal size is “b0”, and the relative position (for example, the shift amount is (x0, y0)). When the vertical size of the Q key on the screen G2 is “a1” and the horizontal size is “b1”, the shift amount of the Q key on the calibration screen G2 is (x0 × a1 / a0, y0 × b1 / b0).
