Description

  The present invention relates to a mobile terminal including a touch panel, and more particularly to improvement of a user interface.

In order to detect a touch on the touch panel and obtain a coordinate value, a configuration for converting the output value from the touch panel into a coordinate value (hereinafter referred to as a “coordinate output unit”) is generally required. .
In general, when a plurality of contacts are made on a touch panel that does not support so-called multi-touch such as a resistance film type or a capacitance type surface type, the coordinate output unit displays each contact position. It is known that the coordinate value of an intermediate position is output (for example, patent document 1).

  For example, as a result of the user trying to input a letter “A” and a letter “B” in succession using a software keyboard displayed on the touch panel, one touched to the position Pa of the “A” key. Before releasing the finger, that is, with this one finger in contact, the other finger is brought into contact with the position Pb of the “B” key, and then the finger brought into contact with the position Pa is released. Further, it is assumed that the finger that has been brought into contact with the position Pb is subsequently released.

In this case, the coordinate output unit sequentially outputs the coordinate value of the position Pa, the coordinate value of the intermediate position Pc between the position Pa and the position Pb that is not actually touched by the finger, and the coordinate value of the position Pb. Will be.
In a general portable terminal that includes a touch panel that does not support multi-touch and a coordinate output unit, and performs processing based on coordinate values output from the coordinate output unit, the key input operation as described above is performed. When it is performed, the contact is started from the position Pa, and the contact position is moved to the position Pb via the position Pc without releasing the contact (so-called drag operation is performed), and assigned to the position Pb. The processed processing is executed.

  The process assigned to the position Pb is executed when the user interface that performs input by selecting a so-called button such as a software key is used, and the process assigned to the position where the contact is separated on the touch panel. This is because the specification to be executed is generally used.

JP 2004-206681 A

However, in the above-described general mobile terminal, a process assigned to the position Pb is executed on the assumption that a so-called drag operation is performed from the position Pa to the position Pb via the position Pc, but the assignment is made to the position Pa. The processed processing will not be executed.
That is, in the above-described example, the user does not input the character “A” even though the user intends to input the characters “A” and “B” successively.

  Therefore, the present invention has been made in view of such problems, and provides a mobile terminal capable of appropriately executing processing according to a user operation such as key input on a touch panel that does not support multi-touch. With the goal.

  In order to solve the above-described problem, the mobile terminal according to the present invention outputs a coordinate value of the touch position when a single touch is made to the touch panel and the touch panel, and a plurality of touches to the touch panel. Are simultaneously performed, a coordinate output unit that outputs coordinate values of intermediate positions of all contact positions, and three coordinate values that are sequentially output from the coordinate output unit are represented by a first coordinate value and a second coordinate value. In the case of the third coordinate value, when the second coordinate value indicates an intermediate position between the first coordinate value and the third coordinate value, the first coordinate value is transmitted and the coordinate output unit outputs the coordinate. When a value changes from an output state to a non-output state, a control unit that sends out the coordinate value that was output immediately before, and an execution that executes processing according to the coordinate value sent from the control unit And a section.

  According to the mobile terminal according to the present invention having the above-described configuration, it is possible to appropriately execute a process according to a user operation such as key input on a touch panel that does not support multi-touch.

A mobile phone as an embodiment of a mobile terminal according to the present invention will be described below.
<< Embodiment >>
<Device configuration>
First, the device configuration of the mobile phone 100 according to the embodiment will be described.
1A is a perspective view showing an external appearance of the mobile phone 100 in a closed state, FIG. 1B is a perspective view showing an external appearance of the mobile phone 100 in an open state, and FIG. FIG. 2 is a front view showing an external appearance of mobile phone 100 in an open state.

As shown in FIGS. 1A to 1C, the mobile phone 100 is a so-called slide-type terminal in which the first housing 1 and the second housing 2 are relatively movable. The housing 1, the second housing 2, and the connection mechanisms 4 and 4 ′ that connect the first housing 1 and the second housing 2 are provided.
The first housing 1 is provided with a touch panel 110, a speaker 7 and a microphone 8, and the second housing 2 is provided with a touch panel 120.

As shown in FIGS. 1A and 1B, a guide groove 6 is provided on a side surface of the second housing 2 on which the coupling mechanism 4 is provided. Similarly, a guide groove is provided on the side surface of the second housing 2 where the coupling mechanism 4 ′ is provided.
As shown in FIGS. 1A and 1B, the connecting mechanism 4 includes a connecting piece 5 and pins 30 and 31 for connecting the side surface of the first housing 1 and the side surface of the second housing 2 to each other. have. Moreover, as shown in FIG.1 (c), connection mechanism 4 'similarly has connection piece 5' and pins 30 'and 31'.

The pins 30 and 30 ′ are pivotally supported by the first housing 1, and the pins 31 and 31 ′ are engaged with the respective guide grooves. As the pins 31 and 31 ′ slide along the guide grooves, the first casing 1 and the second casing 2 move relatively.
As shown in FIG. 1A, the mobile phone 100 is connected to the second casing 2 from the closed state where the first casing 1 is overlaid and the touch panel 120 cannot be visually recognized. The first casing 1 moves along the surface of the second casing 2 by sliding along the guide grooves 31 ′, and then the pins 30, 30 ′ are respectively centered on the pins 31, 31 ′. 1 (b) and (c), the surface of the first housing 1 and the surface of the second housing 2 are in an open state in which they are aligned on substantially the same plane. 120 becomes visible.

<Input screen>
Next, an input screen displayed on the mobile phone 100 will be described.
2 to 5 are diagrams showing display examples of the input screens G1 to G4 according to the open / close state of the mobile phone 100 and the orientation of the housing.
The input screens G1 to G4 are screens that are displayed when the mobile phone 100 receives a predetermined user operation.

For example, the input screen G1 shown in FIG. 2 is a screen that is displayed when a predetermined user operation is accepted when the open / close state of the mobile phone 100 is “closed” and the orientation of the housing is “vertical”. It is.
Each input screen (G1 to G4) includes a software keyboard (D1 to D4) and an input field (D5 to D8), and each software keyboard (D1 to D4) particularly has a different alphabet. Multiple keys representing the characters of are included.

2 to 5, each rectangular range indicated by a solid line in each software keyboard indicates the range of each key, and is displayed so that the user can visually recognize the range of each key. In the following, for example, a key displaying “Q” is expressed as “Q key”, and a key displaying other characters is expressed in the same manner.
In addition, hereinafter, when the user touches the range of each key with a finger or the like, it is referred to as touching the key or selecting the key.

When the user selects a key, mobile phone 100 accepts input of a character represented by the selected key, and displays the accepted character in the input field.
Here, when a user selects a key and inputs a character, for example, to quickly input a character using both hands, the finger or the like is contacted with another key while keeping the finger or the like in contact with one key. There is a case to let you.

FIG. 6 is a diagram illustrating a state in which the user of the mobile phone 100 selects a key constituting the software keyboard D4 and performs character input.
In the figure, the user tries to input the letter “A” and the letter “L” in succession before releasing the little finger of the left hand from the A key, that is, while touching the A key, A state in which the ring finger is brought into contact with the L key is shown.

Here, each touch panel included in the mobile phone 100 does not support so-called multi-touch, and when a plurality of touches occur simultaneously on each touch panel, the output value from each touch panel is expressed as a coordinate value. Each coordinate output unit (details will be described later) that converts and outputs the coordinate value of the intermediate position of each contact position is output.
That is, as shown in the figure, with the little finger of the left hand in contact with the A key, the ring finger of the right hand is brought into contact with the L key, then the A key is released, and then the L key is released. In this case, from the coordinate output unit of the touch panel 120 of the mobile phone 100, the coordinate value of the position P1 where the little finger of the left hand is in contact and the intermediate position P2 between the position P1 and the position P3 where the ring finger of the right hand is in contact And the coordinate value of the position P3 are sequentially output.

  In such a case, when adopting a user interface that performs input by selecting a so-called button such as a key, it is common to have a specification that executes a process assigned to a position where contact is separated on the touch panel. Therefore, in the case of the conventional general mobile phone, the contact is started from the position P1, and the contact position is moved to the position P2 via the position P3 without releasing the contact (so-called drag operation was performed). As an example, only the process assigned to the position P3 (in this example (input of the letter “L” in the example of FIG. 6) is executed.

That is, in the example of FIG. 6, the user wants to input the characters “A” and “L”, but the conventional general mobile terminal can only input the characters “L”. It will be.
When the mobile phone 100 according to the embodiment of the present invention sequentially outputs the coordinate value of the position P1, the coordinate value of the position P2, and the coordinate value of the position P3 from each coordinate output unit at regular time intervals, When the coordinate value of the position P2 is an intermediate coordinate value between the position P1 and the position P3, the processing assigned to the position P1 (that is, the input of the character “A” in the example of FIG. 6) is performed. Processing intended by the user can be performed.

Note that the types, arrangement order, and arrangement of keys arranged on the input screen displayed on each touch panel of the mobile phone 100 are examples, and can be changed as appropriate.
<Functional configuration>
FIG. 7 is a block diagram showing a functional configuration of main parts of the mobile phone 100.

  The mobile phone 100 includes a communication unit included in a normal mobile phone, the speaker 7, the microphone 8, and the like shown in FIG. 1, which are not shown in the figure. In addition, the mobile phone 100 includes a processor and a memory, and each function of the control unit 150 and the execution unit 160 is realized by the above-described processor executing a program stored in the above-described memory. The

Here, the touch panel 110 includes a display unit 111 and a sensor unit 112, and the touch panel 120 includes a display unit 121 and a sensor unit 122.
Each display unit (111, 121) is a circuit that includes an LCD (Liquid Crystal Display) and displays images such as characters and icons on the LCD in response to an instruction from the control unit 150. The number of pixels of each LCD is assumed to be 480 × 800 pixels as an example. Note that the number of pixels of the LCD is not limited to 480 × 800 pixels, and other pixel numbers can be used as appropriate.

Each sensor unit (112, 122) is a touch sensor that does not support so-called multi-touch. In the following, it is assumed that it is a resistive film type touch sensor.
In addition, each coordinate output unit (113, 123) detects the touch of the user's finger or the like in each sensor unit (112, 122), and during the detection, the touch is performed at regular intervals (for example, 25 ms). It is an IC (Integrated Circuit) that outputs a coordinate value (x, y) obtained by detecting a voltage proportional to the contact position in the sensor to the control unit 150.

Here, the coordinate value (x, y) output from each coordinate output unit becomes the coordinate value of the contact position when one contact is performed, and when a plurality of contacts are performed, It becomes the coordinate value of the middle position of all contact positions.
As shown in FIG. 4, the coordinate value of the upper left vertex of each touch panel (each sensor unit) is (0, 0), and the coordinate value of the lower right vertex is (479, 799). And

The open / close detection sensor 130 has a function of outputting a signal indicating whether the mobile phone 100 is in an open state or a closed state to the control unit 150, for example, a magnet embedded in the first housing 1. This is realized by a Hall sensor that detects the magnetic force of the.
The acceleration sensor 131 has a function of detecting gravitational acceleration generated in the mobile phone 100 and outputting a signal indicating the detection result to the control unit 150, and is realized by, for example, a three-axis acceleration sensor.

The storage unit 140 is a memory area for storing the key information table 10, the first coordinate information table 20, and the second coordinate information table 21.
Here, the key information table 10 is a table in which information indicating the position of each key is registered for each usage state (opening / closing state and orientation of the housing) of the mobile phone 100 (see FIG. 8).
Further, the first coordinate information table 20 is a table in which coordinate values received from the coordinate output unit 113 and the second coordinate information table 21 from the coordinate output unit 123 are registered in order, respectively.

In addition to the control functions of a general mobile phone, the control unit 150 is an execution unit based on the use state (opening / closing state and orientation of the housing) of the mobile phone 100 and the coordinate values received from each coordinate output unit. 160 has a function of notifying various events.
The control unit 150 includes a contact determination unit 151, a state determination unit 152, an intermediate position determination unit 153, a display control unit 154, and an event notification unit 155.

Here, the contact determination unit 151 detects the presence / absence of contact on each touch panel based on the reception of the coordinate value sent from each coordinate output unit, and the coordinate value received from each coordinate output unit at regular intervals. A function of sequentially registering in the corresponding coordinate information table (the first coordinate information table 20 or the second coordinate information table 21).
When the user operates the touch panel (110 or 120) relatively slowly, the coordinate value having the same value as the previously received coordinate value is obtained from the coordinate output unit (113 or 123) corresponding to the touch panel. The case of receiving is considered. Therefore, in such a case, the contact determination unit 151 loads the corresponding coordinate information table (the first coordinate information table 20 or the second coordinate information table 21) until the next different coordinate value is received from the coordinate output unit. Coordinate values are not registered.

In addition, the contact determination unit 151 has a function of instructing the event notification unit 155 to notify one of a PRESS event and a RELEASE event in accordance with a change in the contact detection state in each touch panel.
Here, the PRESS event is an event indicating that the touch to the touch panel is started, which is notified when the touch is detected in each touch panel and the touch is detected, and is detected. And the identification information (hereinafter referred to as “panel ID”) indicating which touch panel the coordinate value is used for are designated.

Further, the RELEASE event is an event indicating that the touch on the touch panel is completed, which is notified when the touch is detected from each touch panel to a state where no touch is detected. The coordinate value and panel ID used for detection when contact is detected are specified.
The panel ID specified in the event is identification information indicating the touch panel 110 if the coordinate value specified together with the panel ID is transmitted from the coordinate output unit 113, and is transmitted from the coordinate output unit 123. If it is, it is identification information indicating the touch panel 120.

The state determination unit 152 has a function of determining the usage state of the mobile phone 100 based on the signals output from the open / close detection sensor 130 and the acceleration sensor 131.
As shown in FIG. 4, the casings 1 and 2 have a portrait orientation (hereinafter referred to as “vertical orientation”) and a landscape orientation shown in FIG. , "Landscape"). Based on the signal output from the acceleration sensor 131, the state determination unit 152 specifies the direction of the casing of the mobile phone 100 in a direction closer to the vertical direction or the horizontal direction.

When the determination result changes, the state determination unit 152 instructs the event notification unit 155 to notify the state change event specifying the changed usage state.
When the coordinate value is registered in the coordinate information table (the first coordinate information table 20 or the second coordinate information table 21), the intermediate position determination unit 153 has three coordinate values registered most recently (in the following, registration is not performed). Based on the first coordinate value, the second coordinate value, and the third coordinate value in order from the previous one), the second coordinate value is an intermediate position between the position indicated by the first coordinate value and the position indicated by the third coordinate value. It has a function to determine whether or not.

Further, when the intermediate position determination unit 153 determines that the second coordinate value indicates the intermediate position, the intermediate position determination unit 153 notifies the RELEASE event specifying the first coordinate value and the panel ID, and the second coordinate value is intermediate. When it is determined that the position is not indicated, the event notification unit 155 is instructed to notify the MOVE event that designates the second coordinate value and the panel ID.
Here, the MOVE event is an event indicating that the touch position has been moved without ending the touch on the touch panel once started.

The panel ID specified in the event is identification information indicating the touch panel 110 if the coordinate value specified together with the panel ID is registered in the first coordinate information table 20, and the second coordinate information. If it is registered in the table 21, it is identification information indicating the touch panel 120.
The display control unit 154 has a function of controlling display on each display unit based on an instruction from the execution unit 160.

The event notification unit 155 has a function of notifying the execution unit 160 of various events in accordance with instructions from the contact determination unit 151, the state determination unit 152, and the intermediate position determination unit 153.
Hereinafter, the PRESS event, the MOVE event, and the RELEASE event are collectively referred to as a “panel event”.
The execution unit 160 has a function of executing processing corresponding to the event notified from the event notification unit 155 and includes a key specifying unit 161 and a panel event processing unit 162.

Here, when the panel event is notified, the key specifying unit 161 receives the key that exists at the position indicated by the coordinate value specified in the panel event, and the change specified in the state change event most recently received. It has a function of specifying based on the later use state and the key information table 10 of the storage unit 140.
The panel event processing unit 162 has a function of executing processing associated with a panel event in advance when the panel event is notified.

For example, when a PRESS event is notified, the display of the key specified by the key specifying unit 161 is updated to a state where the key is selected (hereinafter referred to as “selected state”).
Further, for example, when a MOVE event is notified, the display of the key specified by the key specifying unit 161 is updated to the selected state, and the display is updated to the selected state by the PRESS event previously notified. The display of the key is updated to a state where the key is not selected (hereinafter referred to as “non-selected state”).

Further, for example, when a RELEASE event is notified, a character representing the key specified by the key specifying unit 161 is accepted as an input character, and the input character is displayed in the input field of the input screen. The display of the key selected by the notified PRESS event or MOVE event is updated to the non-selected state.
<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 key information table 10.
As shown in the figure, the key information table 10 is information configured by associating an open / closed state 11, a casing orientation 12, a key ID 13, a panel ID 14, an upper left coordinate value 15, and a lower right coordinate value 16.

It is arranged on the touch panel (touch panel 110), and the upper left coordinate value of the key range is “(x11, y11)”, and the lower right coordinate value is “(x12, y12)”.
<Operation>
Next, the operation of the mobile phone 100 having the above configuration will be described with reference to FIGS.

<Control processing>
9 and 10 are flowcharts showing control processing by the control unit 150 of the mobile phone 100. FIG.
The control process shown in the figure is the input screen (any one of G1 to G4) corresponding to the use state after the change specified by the state change event that the mobile phone 100 has received a predetermined user operation and has already been notified of. ) Is displayed.

In addition, when the input screens G1 and G2 are displayed, the control processing shown in the figure is performed for the input from the touch panel 110, and when the input screen G4 is displayed, the input from the touch panel 120 is performed. The control process shown in FIG.
Further, when the input screen G3 is displayed, it is necessary to perform the control processing shown in the figure for each of the touch panels (110, 120).

In the following, the changed use state specified in the already notified state change event indicates that the open / close state is “open” and the housing orientation is “lateral”, and the input screen G4 is The flow of control processing for input from the touch panel 120 will be described by taking as an example a case where the user directly inputs alphanumeric characters.
First, the control unit 150 initializes the second coordinate information table 21, that is, deletes all coordinate values registered in the second coordinate information table 21 (step S1 in FIG. 9).

Subsequently, the contact determination unit 151 determines whether contact on the touch panel 120 has been detected based on whether the coordinate value is received from the coordinate output unit 123 (step S2).
When the coordinate value is not received from the coordinate output unit 123, the contact determination unit 151 determines that no contact is detected (step S2: NO), and a predetermined time (in this example) from the previous execution of the process of step S2. Then, the process of step S2 is executed again so that the interval becomes 25 ms).

When the coordinate value is received from the coordinate output unit 123, the contact determination unit 151 determines that contact has been detected (step S2: YES), and registers the received coordinate value in the second coordinate information table 21. (Step S3).
Further, the contact determination unit 151 instructs the event notification unit 155 to notify the PRESS event that designates the coordinate value registered in step S3 and the panel ID “2”, and the event notification unit 155 determines the PRESS event based on the instruction. Is notified to the execution unit 160 (step S4).

Moreover, the contact determination part 151 determines whether the contact in the touch panel 120 was detected similarly to said step S2 (step S5). In addition, the contact determination part 151 performs the process of step S5 so that it may become a fixed time (25 ms in this example) interval after performing the process of step S2 last.
When it is determined that no contact has been detected (step S5: NO), the contact determination unit 151 notifies the RELEASE event specifying the coordinate value most recently registered in the second coordinate information table 21 and the panel ID “2”. The event notification unit 155 is instructed. Based on this instruction, the event notification unit 155 notifies the RELEASE event to the execution unit 160 (step S9), and performs the processing from step S1 again.

On the other hand, if it is determined that contact has been detected (step S5: YES), the contact determination unit 151 determines whether the coordinate value most recently registered in the second coordinate information table 21 matches the coordinate value received this time. Is determined (step S6).
If the most recently registered coordinate value coincides with the coordinate value received this time (step S6: YES), the contact determination unit 151 is a fixed time (25 ms in this example) from the previous execution of the process of step S5. The process of step S5 is executed again so that the interval is reached.

If the most recently registered coordinate value does not match the currently received coordinate value (step S6: NO), the contact determination unit 151 registers the currently received coordinate value in the second coordinate information table 21 ( Step S7).
Subsequently, the contact determination unit 151 determines whether or not a contact on the touch panel 120 has been detected in the same manner as in step S5 (step S8). In addition, the contact determination part 151 performs this step S8 process so that it may become a fixed time (25 ms in this example) interval after performing the process of step S5 last.

  When it is determined that no contact has been detected (step S8: NO), the contact determination unit 151 notifies the RELEASE event specifying the coordinate value most recently registered in the second coordinate information table 21 and the panel ID “2”. The event notification unit 155 is instructed. Based on this instruction, the event notification unit 155 notifies the RELEASE event to the execution unit 160 (step S9), and performs the processing from step S1 again.

On the other hand, if it is determined that contact has been detected (step S8: YES), the contact determination unit 151 determines whether the coordinate value most recently registered in the second coordinate information table 21 matches the coordinate value received this time. Is determined (step S10).
If the most recently registered coordinate value coincides with the coordinate value received this time (step S10: YES), the contact determination unit 151 is a fixed time (25 ms in this example) from the previous execution of the process of step S8. The process of step S8 is executed again so that the interval is reached.

If the most recently registered coordinate value does not match the currently received coordinate value (step S10: NO), the contact determination unit 151 registers the currently received coordinate value in the second coordinate information table 21 ( Step S11 in FIG.
The intermediate position determination unit 153 is based on the three coordinate values most recently registered in the second coordinate information table 21 (first coordinate value, second coordinate value, and third coordinate value in order from the previous one). It is determined whether or not the second coordinate value indicates an intermediate position between the position indicated by the first coordinate value and the position indicated by the third coordinate value (step S12).

That is, when the first coordinate value is (x1, y1), the second coordinate value is (x2, y2), and the third coordinate value is (x3, y3), x2 = (x1 + x3) / 2 and y2 = When both (y1 + y3) / 2 hold, the intermediate position determination unit 153 determines that the second coordinate value indicates the intermediate position.
When it is determined that the second coordinate value does not indicate the intermediate position (step S12: NO), the intermediate position determination unit 153 notifies the MOVE event specifying the second coordinate value and the panel ID “2” as an event notification unit. 155 is instructed. Based on this instruction, the event notification unit 155 notifies the execution unit 160 of this MOVE event (step S13), and performs the processing from step S5 again.

When it is determined that the second coordinate value indicates the intermediate position (step S12: YES), the intermediate position determination unit 153 notifies the RELEASE event specifying the first coordinate value and the panel ID “2” as an event notification. The event notification unit 155 notifies the execution unit 160 of this RELEASE event based on this instruction (step S14).
Further, the intermediate position determination unit 153 instructs the event notification unit 155 to notify the PRESS event designating the third coordinate value and the panel ID “2”, and the event notification unit 155 determines the PRESS event based on this instruction. The execution unit 160 is notified (step S15), and the processing is performed again from step S5.

  Here, the flow of control processing by the control unit 150 for input from the touch panel 120 has been described, but the flow of control processing by the control unit 150 for input from the touch panel 110 is also the same. However, in the above description, “coordinate output unit 123” is described as “coordinate output unit 113”, “second coordinate information table 21” is described as “first coordinate information table 20”, and “panel ID“ 2 ””. Need to be read as “panel ID“ 1 ””.

<Panel event processing>
FIG. 11 is a flowchart showing processing for a panel event by the execution unit 160 of the mobile phone 100.
The processing for the panel event shown in the figure is started when the input screen (any one of G1 to G4) is displayed, similarly to the control processing by the control unit 150.

Hereinafter, as in the description of the control processing by the control unit 150, an example in which the input screen G4 is displayed and the user directly inputs alphanumeric characters will be described.
First, the execution unit 160 initializes parameters, that is, sets FLAG to “0”, deletes the key set as the previous target key, and deletes the key set as the current target key (step S20). .

Here, FLAG is information indicating whether or not there is a key whose display is selected. When “1”, it indicates that there is a key whose display is selected. And
The current target key is information indicating a key that is determined in step S22 to be described later that the coordinate value specified by the panel event is included in the range. The previous target key is the previous step S22. Is the information indicating the key determined to be included in the range of the coordinate value specified by the panel event.

Subsequently, the execution unit 160 determines whether or not a panel event has been received from the event notification unit 155 (step S21). If no panel event has been received (step S21: NO), the execution unit 160 returns to step S21. Execute the process.
If a panel event has been received (step S21: YES), the key specifying unit 161 indicates that the position specified by the panel ID and coordinate value specified by the panel event is in any key range. Is determined based on the use state after the change specified in the already received state change event and the key information table 10 (step S22).

In this example, it is assumed that the input screen G4 is displayed. Therefore, the key specifying unit 161 has the panel ID “2” associated with “open” in the key information table 10 and “horizontal” in the open / closed state, the upper left coordinate value and the lower right for each key. Get the coordinate value.
The key specifying unit 161 specifies the upper left coordinate value and the lower right coordinate value for each acquired key when the acquired panel ID “2” matches the panel ID specified by the panel event. Affirmative determination (step S22: YES) is performed only when the coordinate value specified by the panel event is included in the range of each key (rectangular region).

  When an affirmative determination is made in step S22 (step S22: YES), the key specifying unit 161 has a key that is different from the key determined to include the coordinate value specified in the panel event within the range. If it is already set as the current target key, set the key as the previous target key, and then select the key that is determined that the coordinate value specified in the panel event is included in the range as the current target key Set (step S23).

Subsequently, the panel event processing unit 162 determines whether the received panel event type is a PRESS event, a RELEASE event, or a MOVE event (step S24).
When the panel event is a PRESS event (step S24: PRESS), the panel event processing unit 162 updates the display of the current target key to the selected state via the display control unit 154 (step S25), and sets FLAG to “ 1 "(step S26), and the processing is performed again from step S21.

  In step S24, when the panel event is a RELEASE event (step S24: RELEASE), the panel event processing unit 162 receives the character represented by the current target key as an input character, and displays the received input character as a display control unit. Via 154, it is displayed in the input field of the currently displayed input screen (in this example, the input field D8 of the input screen G4) (step S27), and the display of the current target key is updated to the non-selected state (step S28). ).

Further, the panel event processing unit 162 sets FLAG to “0” (step S29), and performs the processing from step S21 again.
In step S24, when the panel event is a MOVE event (step S24: MOVE), the panel event processing unit 162 determines whether or not FLAG is “1” (step S30). In the case of “0” (step S30: NO), the processing is performed from step S25.

When FLAG is “1” (step S30: YES), the panel event processing unit 162 updates the display of the previous target key to the non-selected state via the display control unit 154 (step S31). ), The process is performed from step S25.
On the other hand, when it is determined in step S22 that the coordinate value specified by the panel event is not included in any key range (step S22: NO), the panel event processing unit 162 sets FLAG to “1”. ] Is determined (step S32).

If FLAG is not “1” (step S32: NO), the process is performed again from step S21. If FLAG is “1” (step S32: YES), the process is performed from step S28.
<Description of operation by specific example>
The operation of the mobile phone 100 described above will be described using the specific example shown in FIG. 6 in accordance with the flowcharts shown in FIGS.

In the following, as shown in FIG. 6, on the input screen G4, while the user is touching the left finger little finger to the A key, the user touches the ring finger of the right hand to the L key. A case will be described as an example where the key is released from the key and then the right finger is released from the L key.
<Selection of A key>
First, the control unit 150 initializes the second coordinate information table 21 (step S1 in FIG. 9). In this example, since the user makes contact with the A key, the coordinate of the contact position P1 is obtained from the coordinate output unit 123. Since the value is received, the contact determination unit 151 determines that the touch on the touch panel 120 has been detected (step S2: YES), and registers the received coordinate value of the contact position P1 in the second coordinate information table 21. (Step S3).

Further, the contact determination unit 151 instructs the event notification unit 155 to notify the PRESS event specifying the coordinate value of the contact position P1 and the panel ID “2”, and the event notification unit 155 transmits the PRESS event based on the instruction. The execution unit 160 is notified (step S4).
The execution unit 160 receives this PRESS event (steps S20 and S21 in FIG. 11: YES), and in this example, the coordinate value specified by this PRESS event (the coordinate value of the contact position P1) is in the range of the A key. (Step S22: YES), the key specifying unit 161 sets the A key as the current target key (step S23).

Subsequently, since the type of the received panel event is a PRESS event (step S24: PRESS), the panel event processing unit 162 updates the display of the current target key (A key) to the selected state via the display control unit 154. (Step S25) and FLAG is set to "1" (Step S26).
<Selection of L key while A key is selected>
Next, in this example, since the user makes contact with the L key while making contact with the A key, the contact determination unit 151 receives the coordinate value of the position P2 from the coordinate output unit 123. Therefore, the contact determination unit 151 determines that the contact on the touch panel 120 has been detected (step S5 in FIG. 9: YES), and the coordinate value (coordinate value of the contact position P1) most recently registered in the second coordinate information table 21 Then, it is determined that the coordinate value received this time (the coordinate value at the position P2) does not match (step S6: NO). Therefore, the contact determination unit 151 registers the coordinate value received this time (the coordinate value of the position P2) in the second coordinate information table 21 (step S7).

<Deselect A key>
Next, in this example, since the user releases the contact with the A key, the contact determination unit 151 receives the coordinate value of the contact position P3 from the coordinate output unit 123, so the contact on the touch panel 120 is detected. (Step S8: YES), and the coordinate value most recently registered in the second coordinate information table 21 (the coordinate value of the position P2) does not match the coordinate value received this time (the coordinate value of the contact position P3). Determination is made (step S10: NO). Therefore, the contact determination unit 151 registers the coordinate value (the coordinate value of the contact position P3) received this time in the second coordinate information table 21 (step S11 in FIG. 10).

  In this example, the second coordinate value (coordinate value of the position P2) registered in the second coordinate information table 21 is an intermediate position between the position P1 indicated by the first coordinate value and the position P3 indicated by the third coordinate value. (Step S12: YES), the intermediate position determination unit 153 instructs the event notification unit 155 to notify the RELEASE event specifying the first coordinate value (the coordinate value of the contact position P1) and the panel ID “2”. Based on this instruction, the event notification unit 155 notifies the execution unit 160 of this RELEASE event (step S14).

The execution unit 160 receives this RELEASE event (step S21 in FIG. 11: YES), and in this example, the coordinate value specified by this RELEASE event (the coordinate value of the contact position P1) is included in the range of the A key. (Step S22: YES), the A key is set to the current target key (step S23).
Subsequently, since the type of the received panel event is a RELEASE event (step S24: RELEASE), the panel event processing unit 162 accepts the character “A” represented by the current target key as an input character, and displays the accepted input character. The information is displayed in the input field D8 of the input screen G4 via the control unit 154 (step S27), and the display of the current target key (A key) is updated to a non-selected state (step S28). Further, the panel event processing unit 162 sets FLAG to “0” (step S29).

Further, the intermediate position determination unit 153 instructs the event notification unit 155 to notify the PRESS event specifying the third coordinate value (the coordinate value of the contact position P3) and the panel ID “2”, and the event notification unit 155 Based on, this PRESS event is notified to the execution unit 160 (step S15 in FIG. 10).
The execution unit 160 receives this PRESS event (step S21 in FIG. 11: YES), and in this example, the coordinate value (coordinate value of the contact position P3) specified by this PRESS event is included in the range of the L key. Therefore (step S22: YES), the key specifying unit 161 sets the A key already set as the current target key as the previous target key, and sets the L key as the current target key (step S23).

Subsequently, since the type of the received panel event is a PRESS event (step S24: PRESS), the panel event processing unit 162 updates the display of the current target key (L key) to the selected state via the display control unit 154. (Step S25) and FLAG is set to "1" (Step S26).
<Deselect L key>
Next, in this example, since the user releases the contact with the L key, the contact determination unit 151 does not receive the coordinate value from the coordinate output unit 123, and therefore determines that the contact on the touch panel 120 is not detected ( In step S5 of FIG. 9: NO), the contact determination unit 151 notifies the RELEASE event specifying the coordinate value (coordinate value of the contact position P3) most recently registered in the second coordinate information table 21 and the panel ID “2”. The event notification unit 155 is instructed. Based on this instruction, the event notification unit 155 notifies the execution unit 160 of this RELEASE event (step S9).

The execution unit 160 receives this RELEASE event (step S21 in FIG. 11: YES), and in this example, the coordinate value specified by this RELEASE event (the coordinate value of the contact position P3) is included in the range of the L key. (Step S22: YES), the L key is set to the current target key (step S23).
Subsequently, since the type of the received panel event is a RELEASE event (step S24: RELEASE), the panel event processing unit 162 accepts the character “L” represented by the current target key as an input character, and displays the accepted input character. The information is displayed in the input field D8 of the input screen G4 via the control unit 154 (step S27), and the display of the current target key (L key) is updated to a non-selected state (step S28). Further, the panel event processing unit 162 sets FLAG to “0” (step S29).

<Supplement>
As described above, the mobile terminal according to the present invention has been described based on the embodiment. However, the mobile terminal can be modified as follows, and the present invention is limited to the mobile phone as described in the above-described embodiment. Of course not.
(1) In the embodiment, in the control process, when the second coordinate value indicates the intermediate position between the first coordinate value and the third coordinate value, the intermediate position determination unit 153 always sets the event notification unit 155 to As described above, the RELEASE event designating the first coordinate value is notified (step S12 in FIG. 10: YES, S14).

However, when a user operation for displaying a character represented by a key including the position indicated by the first coordinate value in the range as an input character candidate and determining the candidate as an input character is performed, the event notification unit 155 is displayed. The RELEASE event that designates the first coordinate value may be notified through this. Hereinafter, the mobile phone according to this modification is referred to as a “modified mobile phone”.
Specifically, a part of the control process (part shown in FIG. 10) is transformed as shown in FIG. 13, and the process for the panel event shown in FIG. 11 is transformed as shown in FIG.

  The modified mobile phone control process (especially see FIG. 13) includes the process of steps S16 to S19 between steps S12 and S14 (particularly see FIG. 10). And different. Further, the processing for the panel event of the modified mobile phone shown in FIG. 14 includes the processing of steps S33 and S34 between steps S22 and S23, and the panel of the mobile phone 100 according to the embodiment shown in FIG. It is different from processing for events.

Hereinafter, the control process for the modified mobile phone and the process for the panel event will be described focusing on the difference between the control process for the mobile phone 100 and the process for the panel event.
First, the control process of the modified mobile phone will be described by taking as an example the case where the input screen G4 is displayed.
In addition, since the process of step S1-S11 is the same as the mobile phone 100 among control processes of a deformation | transformation mobile telephone (refer FIG.9, 10 steps S1-S11), description is abbreviate | omitted.

  The intermediate position determination unit (hereinafter referred to as “deformed intermediate position determination unit”) of the modified mobile phone uses the second coordinate value registered in the second coordinate information table 21 as the position indicated by the first coordinate value and the third coordinate value. Is determined to indicate an intermediate position (step S12 in FIG. 13: YES), the first coordinate value is determined via the event notification unit (hereinafter referred to as “deformation event notification unit”) of the modified mobile phone. And the TMP-RELEASE event designating the panel ID is notified (step S16).

Subsequently, the contact determination unit 151 determines whether or not the touch on the touch panel 120 is detected based on whether or not the coordinate value is received from the coordinate output unit 123 (step S17), and does not detect the contact. (Step S17: NO), the process of step S17 is performed again.
If it is determined that contact has been detected (step S17: YES), the contact determination unit 151 notifies the PRESS event specifying the received coordinate value and panel ID via the deformation event notification unit (step S17). S18).

The deformation intermediate position determination unit receives a notification from the execution unit (hereinafter referred to as “deformation execution unit”) of the modified mobile phone, and determines the type of the received notification (step S19).
If the received notification is a notification that the input character candidate is determined as the input character (step S19: determination notification), the process proceeds to step S14, and the received notification determines that the input character candidate is the input character. If the notification is not determined to be determined (step S19: non-decision notification), the process proceeds to step S13.

Next, the process for the panel event of the modified mobile phone shown in FIG. 14 will be described by taking the case where the input screen G4 is displayed as an example.
As described in the embodiment, when the processing of step S20 to step S22 is completed, the panel event processing unit of the modified mobile phone (hereinafter referred to as “modified panel event processing unit”) receives the received event as a TMP-RELEASE event. (Step S33). If it is not a TMP-RELEASE event (step S33: NO), the process proceeds to step S23.

If the event is a TMP-RELEASE event (step S33: YES), a confirmation process is performed (step S34). When the confirmation process is completed, the process is performed again from step S21.
Hereinafter, the confirmation process will be described with reference to FIG.
For example, as shown in FIG. 12, the deformation panel event processing unit displays the character represented by the key determined to be included in the range of the coordinate value specified in the TMP-RELEASE event in the process of step S <b> 22. A window 40 including a character candidate 41, a Yes key 42, and a No key 42 is displayed via the display control unit 154 (step S40).

Here, FIG. 12 is a diagram illustrating a state in which the user of the modified mobile phone selects a key constituting the software keyboard D4 and inputs characters.
In the figure, when the user touches the ring finger of the right hand with the L key while the little finger of the left hand is in contact with the A key, “A” is displayed as the input character candidate 41. An example is shown.

Subsequently, the deformation panel event processing unit determines whether or not a PRESS event has been received (step S41 in FIG. 15).
If the PRESS event has not been received (step S41: NO), the process of step S41 is performed again.
When the PRESS event is received (step S41: YES), the key specifying unit according to this modification includes the coordinate value specified by the PRESS event within the range of the Yes key 42 shown in FIG. Or whether it falls within the range of the No key 43 (step S42).

When included in the range of the Yes key 42 shown in FIG. 12 (step S42: Yes key), the control unit of the modified mobile phone (hereinafter referred to as “deformation control unit” indicates that the input character candidate has been determined as the input character. ”) (Step S43).
In addition, when it is included in the range of the No key 43 shown in FIG. 12 (step S42: No key), the transformation control unit is notified that the input character candidate has not been determined as the input character (step S44). .

When the process of step S43 or S44 is completed, the deformation panel event processing unit deletes the display of the window 40 displayed in step S40 via the display control unit 154, that is, before the window 40 is displayed in step S40. A screen is displayed (step S45), and the confirmation process is terminated.
Here, as an example of a user operation for determining an input character candidate as an input character, the selection operation of the Yes key 42 displayed on the window 40 has been described, but other operations may be performed. Good.

For example, instead of displaying the Yes key 42 and No key 43 of the window 40, a message such as “Select Y key if YES, N key if NO” is displayed, and the Y key selection operation is performed for the input character. It is good also as user operation to determine a candidate as an input character.
(2) Although the mobile phone 100 according to the embodiment has been described as including two touch panels, each touch panel is arranged on substantially the same plane as described in the embodiment. It is not restricted to a case, Moreover, it is good also as what is provided with only one touch panel like the thing provided with three or more touch panels, for example, the straight type terminal shown in FIG.

A cellular phone 200 shown in the figure includes a speaker 201, a microphone 202, and a touch panel 210 in one housing, and a numeric keypad button D9, a call button D10, and an input field D11 are displayed on the touch panel 210.
As shown in the figure, when the user tries to select the 1 key and the 3 key in succession and the left thumb is in contact with the 1 key and the right thumb is in contact with the 3 key, When the thumb of the left hand is released from the 1 key and then the thumb of the right hand is released from the 3 key, the numbers “1” and “3” are sequentially accepted as input, as described in the embodiment, They are displayed in order in the input field D11 (see FIGS. 9 to 11).

  When the mobile phone 100 is modified to include one touch panel, it is not necessary to specify a panel ID for each event, and it is only necessary to store one coordinate information table in the storage unit 140. Further, it is sufficient to register the upper left coordinate value and the lower right coordinate value of each key when the open / close state is “closed” in the data of the key information table 10 shown in FIG. Registration is not required), and the open / close detection sensor 130 is also unnecessary.

  In the embodiment, the two input screens are selectively displayed according to the orientation of the housing. However, only the input screens in any one direction (for example, “horizontal”) are displayed. May be. In that case, the acceleration sensor 131 is not necessary, and the upper left coordinate value and the lower right coordinate value of each key in the data of the key information table 10 shown in FIG. It is enough to register.

Further, the mobile phone 100 according to the embodiment has been described as a slide-type terminal, and the mobile phone 200 illustrated in FIG. 16 has been described as a straight-type terminal. However, the mobile phone 100 may be a mobile phone having another appearance such as a folding type. Good.
Further, a sliding terminal as shown in FIG. 17 may be used.
FIG. 17A is a perspective view showing the external appearance of the mobile phone 300 in a closed state, FIG. 17B is a perspective view showing the external appearance of the mobile phone 300 in an open state, and FIG. FIG. 3 is a front view showing an external appearance of mobile phone 300 in an open state.

As shown in FIGS. 17A and 17B, the mobile phone 300 includes a first housing 301, a second housing 304, and an arm 305 that connects the second housing 304 and the first housing 301. It is composed of
The first housing 301 is provided with a speaker 302, a microphone 303, and a touch panel 310, and the second housing 304 is provided with a touch panel 320.

The base end side of the arm 305 is rotatably supported by the second casing 304, and the distal end side supports the first casing 301 so as to be slidable and rotatable.
As shown in FIG. 17A, the mobile phone 300 is placed in a state where the first housing 301 is overlapped with the second housing 304 and the first housing 301 is moved by the arm 305 from the closed state where the touch panel 320 is not visible. As shown in FIGS. 17B and 17C, the first housing 301 and the second housing 304 are aligned so that the surface of the first housing 301 and the surface of the second housing 304 are aligned on the same plane. The touch panel 310 and 320 becomes visible.

  (3) In the embodiment, it is assumed that alphanumeric characters are directly input using the software keyboard (D1 to D4), and when the RELEASE event is notified, the panel event processing unit 162 indicates that the current target key is It has been described that the character to be represented is received as an input character, and the received input character is displayed as it is in the input field of the input screen via the display control unit 154 (steps S24: RELEASE and S27 in FIG. 11).

However, when the character represented by the current target key is a character (A, I, U, E, and O) representing a vowel, it is converted into hiragana and displayed together with the alphabet that has been accepted as an input character so far. After that, when a predetermined operation (for example, a space key selection operation) is performed, the kanji may be converted.
(4) In the embodiment, a software keyboard (D1 to D4) including a plurality of keys each representing a different alphabetic character is displayed, and the character represented by the selected key is selected by selecting the key. This has been described using an example of accepting and displaying as an input character.

However, for example, a plurality of icons may be displayed, and a corresponding application may be activated when the user selects the icon.
That is, the plurality of keys displayed on the touch panel according to the present invention include not only keys representing letters such as alphabets, numbers, symbols, hiragana and katakana, but also shift keys, space keys, return keys, function keys, numeric keys, and directions. Keys and the like can also be included, and furthermore, various icons for executing processing assigned in advance can be included by selection by the user.

(5) In the embodiment, as shown in FIGS. 9 and 10, it is determined whether or not the newly received coordinate value matches the coordinate value registered most recently. It has been described that the received coordinate values are registered in the table (first coordinate information table 20 or second coordinate information table 21) (steps S6: YES, S7, S10: YES, S11).
However, the processing of steps S6 and S10 is not essential, and when a new coordinate value is received without performing this processing, it may be immediately registered in the corresponding coordinate information table.

(6) In the embodiment, the number of pixels of the LCD of each display unit is the same and the shape of the LCD is substantially rectangular. However, the number of pixels of each display unit may be different. The shape of each display unit may be, for example, a circular shape or other polygonal shapes.
Further, in the mobile phone 100 according to the embodiment, the example in which the input fields (D5 to D8) are displayed on the touch panel has been described. However, the present invention is not limited to such a case, and the input fields (D5 to D8) are displayed. The display screen may be a display screen other than the touch panel, for example, an LCD having no touch panel function, an organic EL (Electro-Luminescence), or the like.

(7) Although the sensor unit (112, 122) of each touch panel according to the embodiment has been described as a resistive film type touch sensor, a touch sensor that does not support so-called multi-touch other than the resistive film type. You may make it use.
For example, a touch sensor that does not support multi-touch includes a conductive film and a substrate, and electrodes are provided at the corners of the substrate to form a uniform electric field by the conductive film. Any suitable method may be used, such as a capacitance type surface type that measures the ratio of the current amount of the terminal to determine the contact position, or an infrared type that detects the position where a finger or the like is in contact with the shielded infrared ray.

  Still further, the mobile terminal according to the present invention detects the contact of the user's finger or the like on the touch sensor, and when one contact is made, the coordinate value of the contact position is used for a plurality of contacts. In this case, as long as a coordinate output unit that outputs the coordinate value of the intermediate position of all the contact positions is provided, instead of the sensor unit (112, 122), a touch sensor other than the touch sensor that does not support the so-called multi-touch described above. A touch sensor (including a touch sensor newly appearing in the future) may be provided.

(8) Of the constituent elements described in the embodiments, all or a part thereof may be realized by an integrated circuit of one chip or a plurality of chips, may be realized by a computer program, or any other method. It may be realized in various forms.
In addition, each component described in the embodiment realizes its function by cooperating with a processor included in the mobile phone.

  (9) A program for causing the processor to execute the processing of the mobile phone described in the embodiment and (1) above (see FIGS. 9 to 11 and 13 to 15) is recorded on a recording medium or various communication paths, etc. It can also be distributed and distributed via Examples of such a recording medium include an IC card, an optical disk, a flexible disk, a ROM (Read Only Memory), and a flash memory. The distributed and distributed program is used by being stored in a memory or the like that can be read by a processor in the device, and the processor executes the program so that the portable device described in the embodiment and (1) above is used. Each function of the telephone is realized.

(10) A part or all of the modifications (1) to (9) may be applied in combination to the mobile phone according to the embodiment.
(11) Hereinafter, the configuration of the mobile terminal according to an embodiment of the present invention, its modification examples, and each effect will be described.
(A) The portable terminal which concerns on one Embodiment of this invention outputs the coordinate value of the said contact position when one contact to a touch panel and the said touch panel is performed, and the some contact to the said touch panel is carried out. When performed simultaneously, the coordinate output unit that outputs the coordinate value of the intermediate position of all the contact positions, and the three coordinate values sequentially output from the coordinate output unit, the first coordinate value, the second coordinate value, and the first coordinate value In the case of three coordinate values, when the second coordinate value indicates an intermediate position between the first coordinate value and the third coordinate value, the first coordinate value is transmitted, and the coordinate value is output from the coordinate output unit. When the state changes from the output state to the non-output state, a control unit that sends the coordinate value output immediately before, and an execution unit that executes processing according to the coordinate value sent from the control unit With.

  For example, the user touches the position indicated by the first coordinate value with a finger or the like so as to continuously execute the processing assigned to each position indicated by the first coordinate value and the third coordinate value. In the meantime, contact of the finger or the like is started at the position indicated by the third coordinate value, and then the finger or the like that is in contact with the position indicated by the first coordinate value is released, and then the third coordinate value indicates Assume that the finger touching the position is released.

In such a case, the coordinate output unit of the portable terminal sequentially outputs the first coordinate value, the second coordinate value indicating the intermediate position between the first coordinate value and the third coordinate value, and the third coordinate value. It will be.
According to this portable terminal, when the second coordinate value indicates an intermediate position between the first coordinate value and the third coordinate value, the process according to the first coordinate value can be executed, and from the coordinate output unit, When the coordinate value is changed from the output state to the non-output state, a process corresponding to the coordinate value output immediately before can be executed. Therefore, in the above-described example, the process assigned to each position indicated by the first coordinate value and the third coordinate value can be executed in order.

(C) Further, the plurality of keys represent mutually different characters, and the execution unit represents the key displayed at the position indicated by the coordinate value as processing according to the coordinate value. Characters may be accepted as input characters, and the input characters may be displayed in another display area different from the display area on the touch panel of the plurality of keys.

  For example, when the user tries to continuously input a character represented by a key displayed at each position indicated by the first coordinate value and the third coordinate value, the user touches the position indicated by the first coordinate value. During this time, contact of a finger or the like is started at the position indicated by the third coordinate value, and then the finger or the like that is in contact with the position indicated by the first coordinate value is released, and then the third coordinate value is It is assumed that a finger or the like that is in contact with the position indicated by is released.

In such a case, according to this portable terminal, the user can input the character represented by the key displayed at each position indicated by the first coordinate value and the third coordinate value, that is, the user intended Character input processing can be executed appropriately.
Further, according to this portable terminal, the received input characters are displayed, so that the user can easily confirm by the display that the input of the key performed by himself / herself has been received.

  (D) The plurality of keys represent mutually different characters, and the execution unit sends the first coordinate value from the control unit as a process according to the coordinate value. The character represented by the key arranged at the position indicated by the first coordinate value is displayed as a candidate for the input character in another display area different from the display area on the touch panel of the plurality of keys, and the input When a user operation for determining a character candidate as an input character is performed, the input character candidate may be accepted as an input character.

According to this portable terminal, when the second coordinate value indicates an intermediate position between the first coordinate value and the third coordinate value, the character represented by the key displayed at the position indicated by the first coordinate value is input character. Since the input character candidate is accepted as an input character after waiting for a user operation, the character input by the user can be specified more accurately.
(E) The portable terminal includes another touch panel different from the touch panel, the plurality of keys represent different characters, and the execution unit performs processing according to the coordinate value. The character represented by the key arranged at the position indicated by the coordinate value is displayed as the input character candidate on the other touch panel, and the input character candidate is determined as the input character on the other touch panel. When the contact operation by the user is performed, the input character candidate may be accepted as the input character.

According to this portable terminal, the same effect as the above (d) can be obtained, and the user can input the input character candidates displayed on the other touch panel more intuitively than the touch operation on the touch panel. It can be determined as a character.
(F) Further, the coordinate output unit outputs the coordinate value at regular time intervals when there is a contact, and the control unit sequentially outputs the coordinate values from the coordinate output unit at the regular time intervals. Of the plurality of coordinate values, the first coordinate value, the second coordinate value, and the third coordinate value may be determined so as to be different from the coordinate values output before the predetermined time. .

The user operates relatively slowly, and for example, the coordinate value A is output a plurality of times at a constant time interval, the coordinate value B is output a plurality of times at a constant time interval, and then the coordinate value is further output. Assume that C is output a plurality of times.
Thus, even when coordinate values of the same value continuously output are included in the plurality of coordinate values output at regular time intervals from the coordinate output unit, according to this portable terminal, the coordinate value A Is the first coordinate value, the coordinate value B is the second coordinate value, the coordinate value C is the third coordinate value, and the second coordinate value indicates an intermediate position between the first coordinate value and the third coordinate value. Processing according to the value can be executed.

That is, according to this portable terminal, the process intended by the user can be appropriately executed.
