  Here, data and programs stored in the mobile terminal device 100 will be described with reference to FIG.

  FIG. 3 shows an arrangement of information stored in the ROM 190 (referred to as a memory map). The memory map includes a program storage area 310 that stores a program that performs various processes in cooperation with the control unit 220, and a data storage area 350 that is used in various processes. The program storage area 310 includes a telephone incoming call program 320, a use state detection program 330, a form change detection program 340, and the like. The data storage area 350 includes an address book 360, notification data 370, and the like.

  A program stored in the program storage area 310 will be described.

  When the user responds to an incoming call and uses the portable terminal device 100 with his / her ear on the ear, the incoming call program 320 changes the form of the portable terminal device 100 unintentionally by the user's unconscious operation. When it does, the process which notifies that the form changed is performed.

  The use state detection program 330 is a program that performs processing for detecting whether or not the user is using the mobile terminal device 100 with the ear.

  The form change detection program 340 is a program that performs processing for detecting whether or not the mobile terminal device 100 has changed in a form not intended by the user.

  The address book 360 stores address information input by user operations. The address information includes a telephone number and an e-mail address, and a name, a memory number, an address, a birthday, a group (for example, information on affiliation such as a school or a work place) associated with the telephone number or the e-mail address are also stored Yes.

  In the notification data 370, when the user is using the mobile terminal device 100 with his / her ear, when the form of the mobile terminal device 100 is changed unintentionally by the user's unconscious operation, the fact that the form has changed Is stored. The notification data 370 includes, for example, the color and time that the light emitting unit 160 emits light. Further, a vibration pattern in which the vibration unit 150 vibrates, a vibration time, and the like are included. Furthermore, information displayed on the display unit 110, information display time, sound output from the microphone 140, and the like are also included. As an example of the notification data 370, an example of information displayed on the display unit 110 is shown in FIG. FIG. 6A shows an example of a screen displayed on the display unit 110 during a call. FIG. 6B shows the display unit 110 when the mobile terminal device 100 is used with the user's unconscious operation when the mobile terminal device 100 is used in contact with the ear. An example of information to be displayed is shown. By displaying information as shown in FIG. 6B on the display unit 110, the user is notified that the form of the mobile terminal device 100 has changed unintentionally, and the harm that the change in form has on the user. Can be prevented.

  In addition to the above, the program storage area 310 and the data storage area 350 store programs and data necessary for executing various functions provided in the mobile terminal device 100. To do.

  Next, a configuration provided in the control unit 220 to execute various functions stored in the mobile terminal device 100 will be described with reference to FIG.

  As shown in FIG. 4, the control unit 220 includes a telephone incoming call processing unit 410, a determination unit 420, a usage state detection unit 430, a form change detection unit 440, a timer unit 450, a notification unit 460, and the like.

  The incoming call processing unit 410 executes the incoming call program 320 stored in the ROM 190.

  The determination unit 420 determines which function provided in the mobile terminal device 100 is an input received from the user by the operation unit 120 or the touch panel input unit 115. For example, the determination unit 420 determines whether the input received from the user by the operation unit 120 or the touch panel input unit 115 is an input for opening the address book 360, or whether the input is for starting a call. It is determined whether the input is for starting an incoming call, whether the operation is for ending a call, or the like.

The usage state detection unit 430 executes a usage state detection program 330 stored in the ROM 190. Here, as an example of the process performed by the use state detection unit 430, a use state detection process in cooperation with the capacitive touch panel input unit 115 will be described. The RAM 200 stores in advance, as a threshold value x, an area that is touch-input at a time when a human ear touches the touch panel input unit 115. In the usage state detection program 330, if the area (defined as the measurement value s) input from the touch panel input unit 115 is equal to or greater than the threshold value x, the user is using the mobile terminal device 100 with his / her ear. to decide. On the other hand, if the input value is less than the threshold value x, it is determined that the user is not using the portable terminal device 100 with his / her ear.
Note that the threshold value x is an average value of results obtained by measuring the contact area when the user touches the touch panel 105 with an arbitrary number of times. By using the average value as the threshold value x, it is possible to detect the usage state in accordance with the user's usage method. Note that the threshold value x may be determined by setting an arbitrary allowable range for the threshold value x in order to detect a usage state in accordance with the user's usage method. The arbitrary allowable range is, for example, a range of a value of ± several% from the threshold value x, and if the measured value s is within the allowable range, the measured value s is regarded as a value equivalent to the threshold value x. Also good. Note that the threshold value t may be a minimum or maximum value among the results of arbitrary number of measurements.

  The form change detection unit 440 executes a form change detection program 340 stored in the ROM 190.

  The timer unit 450 measures the time required for the form of the mobile terminal device 100 to change from the open state to the closed state and from the closed state to the open state in cooperation with the open / close sensor 210.

  Here, a change in form detected by the form change detection unit 440 will be described with reference to FIG. Each drawing in FIG. 5 shows a state in which the mobile terminal device 100 has been slid to change its form. FIG. 5A is a diagram illustrating an open state of the mobile terminal device 100. FIG. 5B is a diagram illustrating a closed state of the mobile terminal device 100. FIG. 5C is a diagram illustrating a state where the form of the mobile terminal device 100 is not completely changed. Here, processing performed by the form change detection unit 440 will be described. The shape change detection unit 440 compares the threshold t (s) with the time required for the shape change of the mobile terminal device 100 measured by the timer unit 450. The threshold value t is because the portable terminal device 100 stored in advance in the ROM 190 changes from the state shown in FIG. 5A to the state shown in FIG. 5B or from the state shown in FIG. 5B to the state shown in FIG. It takes time to complete. The timer unit 450 is configured to change the time from when the mobile terminal device 100 starts to change from the state shown in FIG. 5A to the state shown in FIG. 5C or from the state shown in FIG. 5C to the state shown in FIG. Start measurement. For the sake of explanation, the measurement time is defined as measurement time a.

If the measurement time a is equal to or less than the threshold t, the form change detection unit 440 determines that the user has unintentionally deformed the form of the mobile terminal device 100 by an unconscious operation. On the other hand, when the measurement time “a” exceeds the threshold value “t”, it is determined that the form has not been changed normally. That is, the form change detection unit 440 determines that the form of the mobile terminal device 100 has changed halfway as shown in FIG. Normally, the user does not use the portable terminal device 100 in such a state when the portable terminal device 100 is put on the ear and is used as shown in FIG. If this happens, there is a risk of harm to the user. The harm to the user is, for example, that the user's hair or a foreign object is pinched in the mobile terminal device 100, the mobile terminal device 100 performs an abnormal operation due to the pinched hair, accessories, etc. It is conceivable that an accessory or the like comes into contact with the operation unit 120 provided on the upper surface of the exposed second casing 102 to perform an input unintended by the user, for example, termination of a call. In addition, when notification by sound or vibration is set according to opening and closing, unnecessary notification is performed according to unintended change of form, unnecessary power is consumed by performing unnecessary notification, necessary It is conceivable that the user is prevented from using the function due to the notification without any error. The threshold value t is an arbitrary time detected by the timer unit 450 when the user changes from the state shown in FIG. 5A to the state shown in FIG. 5B or from FIG. 5B to the state shown in FIG. It is good also as an average value of the result of having measured the number of times. By using the average value as a threshold value, it is possible to detect a form change in accordance with the usage method of the user. Note that the threshold value t may be an arbitrary allowable range defined for the measured threshold value t in order to detect a form change in accordance with the user's usage method. The arbitrary allowable range is, for example, a range of a value of ± several% from the threshold value t. The shape change detection unit 440 determines that the measurement time a is the same as the threshold value t if the measurement time a is within the allowable range. It may be determined as a value. Note that the threshold value t may be a minimum or maximum value among the results of arbitrary number of measurements.

  The notification unit 460 stores the notification data stored in the ROM 190 when the mobile terminal device 100 is unintentionally changed by an unconscious operation of the mobile terminal device 100 when the mobile terminal device 100 is used with an ear. 370 is read, and processing for notifying the user that the form of the mobile terminal device 100 has changed is executed.

  In addition to the configuration shown in FIG. 4, the control unit 220 includes a configuration for executing various functions provided in the mobile terminal device 100.

[Operation processing]
Next, the incoming call program 320 executed by the incoming call processing unit 410 will be described with reference to FIG.

In the incoming call program 320, the determination unit 420 first determines whether there is an incoming call to the mobile terminal device 100 via the wireless circuit 170 (S110).
If there is no incoming call to the mobile terminal device 100, the incoming call processing unit 410 continues monitoring until the mobile terminal device 100 receives an incoming call.

  On the other hand, when determining that there is an incoming call to the mobile terminal device 100, the determination unit 420 next determines whether there is an input operation for responding to the incoming call from the operation unit 120 (S120).

  If the determination unit 420 determines that there is no input for a response to the incoming call, the incoming call processing unit 410 notifies the incoming call by the vibration unit 150, the light emitting unit 160, and the display unit 110 (S125).

  On the other hand, if the determination unit 420 determines that there is an input operation for an incoming call, the incoming call processing unit 410 performs processing for starting a call by the wireless circuit 170 (S130).

  The incoming call processing unit 410 executes the processes of S130 to S190 from when the call is started until the call ends.

In S140, the use state detection unit 430 executes the use state detection program 330 to detect whether or not the user is using the mobile terminal device 100 with his / her ear during a call.
An example of processing of the usage state detection program 330 executed by the usage state detection unit 430 will be described with reference to FIG.

  First, the use state detection unit 430 monitors whether there is an input to the touch panel input unit 115 (S210).

  When there is an input on the touch panel 105, the use state detection unit 430 measures the area of the input on the touch panel 105 (S220). In addition, the value measured for description is described as measurement area s here.

  Next, the use state detecting unit 430 reads the input threshold value x of the touch panel 105 stored in advance in the ROM 190 and compares it with the measurement area s (S230). The threshold value x is a contact area when the user touches the touch panel 105 with an ear, and is measured in advance and stored in the ROM 190.

  Next, when the determination unit 420 determines that the value of the measurement area s is smaller than the threshold value x, the use state detection unit 430 performs the call process of S130 illustrated in FIG. 7, that is, continues the call. The value of the measurement area s being equal to or less than the threshold value x is a state where the user does not touch the touch panel 105.

  On the other hand, when the determination unit 420 determines that the value of the measurement area s exceeds the threshold value x, the use state detection unit 430 executes the notification process of S150. The threshold x is equal to or greater than the value of the measurement area s when the user is in contact with the touch panel 105, that is, the user is using the mobile terminal device 100 with the ear.

  Returning to the description of FIG. In S140, when the use state detection unit 430 determines that the mobile terminal device 100 is being used by placing it on the ear, the use state detection unit 430 executes the use state detection program 330 (S150).

  Here, an example of processing performed by the form change detection unit 440 will be described using the flowchart shown in FIG.

  In the form change detection program 340, first, the form change detection unit 440 monitors whether there is a change in form in the mobile terminal device 100 based on the input from the open / close sensor 210 (S310).

When the form change detection unit 440 detects a change in form, that is, when the change from the open state to the closed state or the change from the closed state to the open state is started, the timer unit 450 starts measuring time (S320). Here, for the sake of explanation, the time measured by the timer unit 450 is defined as a measurement time a (s).
Next, the form change detection unit 440 compares the threshold value t with the time a (S330). The threshold value t is a time (s) required for the mobile terminal device 100 to change from the open state to the closed state, or from the closed state to the open state.

  In the process of S330, if the measurement time a is shorter than or equal to the threshold value t, that is, if the change in form is performed normally, the process returns to S150 of FIG. The case where the form change is normally performed is a case where the user intentionally changes the form of the mobile terminal device 100.

  On the other hand, when the measurement time a is longer than the threshold t, that is, when the state change is not performed normally, the process of S160 shown in FIG. 7 is executed.

  Returning to the description of FIG. When the user is using the mobile terminal device 100 with his / her ear while talking on the mobile terminal device 100, when the mobile terminal device 100 is unintentionally changed by an unconscious operation, The notification unit 460 notifies the user that there is a risk of hindering continuation of the call.

  Next, in the process of S170, the determination unit 420 determines whether or not the mobile terminal device 100 has been corrected to a normal form. The determination method is performed by detecting that the open / close sensor 210 has changed to the open state or the closed state again. That is, it is detected whether the use state of the mobile terminal device 100 is halfway open or has been restored from the closed state to the fully open state or the closed state.

  If the determination unit 420 detects that the state of the mobile terminal device 100 has not been corrected, the notification unit 460 continues the notification.

  On the other hand, when the determination unit 420 determines that the state of the mobile terminal device 100 has been corrected to a normal state, the determination unit 420 next determines whether or not there is an operation for terminating the call.

  When the determination unit 420 determines that there is an operation to end the call, the incoming call processing unit 410 ends the call.

  On the other hand, when the determination unit 420 determines that there is no operation to end the call, the process returns to S130 and the call is continued.

[Modification]
The above-described embodiment is an example of the mobile terminal device 100 of the present invention, and can be appropriately changed within the scope described in the embodiment of the present invention.
In the present embodiment, the response to an incoming call has been described as an example of using it against the ear. However, as used when applied to the ear, there are telephone call, recorded message reproduction, message recording, music data reproduction, etc. included.

  For example, the present invention can also be implemented in a mobile terminal device 1000 that includes two touch panels 105 as shown in FIG. Changes in the form shown in FIGS. 10A, 10B, and 10C correspond to changes in the form of the mobile terminal device 100 shown in FIGS. 5A, 5B, and 5C. In the mobile terminal device 1000, one or both of the two touch panels 105 may have a function performed by the operation unit 120. The use state may be detected by the touch panel 105 arranged on the upper side when the portable terminal device 1000 is folded out of the two touch panels. Note that the reference numerals assigned to the mobile terminal apparatus 1000 shown in FIG. 10 and the reference numerals attached to the mobile terminal apparatus 100 shown in the present embodiment indicate corresponding configurations.

  For example, a proximity sensor may be provided as a sensor that detects whether or not the user is using the mobile terminal device 100 against the ear. In the detection of the usage state using the proximity sensor, the user can detect whether there is a measurement object within a predetermined distance from the sensor, instead of the area measured by the touch panel in this embodiment, so that the user can Determine if you are using the device against your ear. That is, the use state is detected based on whether or not the user has approached within the detection distance of the proximity sensor.

  For example, in the present embodiment, the use state is determined by measuring the area in contact with the touch panel, but the use state may be detected based on the shape of the object in contact with the touch panel instead of the area. That is, the input when the user touches the touch panel with the ear (here, the shape touched when the ear touches the touch panel is the measurement target) is stored in the ROM 190 as a threshold value. And it is good also as detecting a use condition by comparing the input when a user touches an ear with a touch panel, and the threshold value memorized beforehand.

  For example, an illuminance sensor may be provided in the vicinity of the touch panel 105 as a sensor for detecting whether or not the user is using the mobile terminal device 100 with his / her ear. In this case, the ROM 190 stores in advance a value in which a certain allowable range is provided for the ambient illuminance before the start of a call and the illuminance when the user uses the mobile terminal device 100 against the ear. The certain allowable range is obtained by providing a range of ± several percent value for the measured illuminance. If the illuminance measured by the illuminance sensor during a call becomes a value within the allowable range of illuminance used by applying to the ear stored in the ROM 190 in advance, the use state detection unit 430 is carried by the user. It is determined that the terminal device 100 is being used by placing it on the ear. On the other hand, when the illuminance measured by the illuminance sensor changes to a value outside the allowable range stored in the ROM 190 in advance, the use state detection unit 430 is used by the user placing the mobile terminal device 100 on the ear. Is determined to have been interrupted.

  For example, the illuminance sensor may be provided on the front and back of the mobile terminal device 100 to detect the usage state. Specifically, when the illuminance detected by the illuminance sensors provided on the front surface and the back surface is substantially equivalent, the usage state detection unit 430 indicates that the user is not using the mobile terminal device 100 by placing it on the ear. to decide. On the other hand, when there is a certain difference in the illuminance detected by the illuminance sensors provided on the front surface and the back surface, the use state detection unit 430 determines that the user is using the mobile terminal device 100 with his / her ear.

  For example, the notification performed by the notification unit 460 may be notified by blinking information displayed on the display unit 110. By flashing notification, when the user is using the mobile terminal device 100 by putting it on his / her ear, it is easy for the user to change the form of the mobile terminal device 100 unintentionally by an unconscious operation. You can notice.

  For example, when the form of the mobile terminal device 100 is changed after the user performs a predetermined input from the touch panel 105 or the operation unit 120, the incoming call processing unit 410 is a change in form based on the user's will. Judgment is made and notification is not performed.

  For example, when there is an input for interrupting the incoming call program 320 from the operation unit 120 or the touch panel 105, the incoming call program 320 is assumed to interrupt the incoming call program 320 when any processing is executed. Also good.

  For example, the mobile terminal device 100 may include an input invalidation unit that invalidates input from the touch panel 105 and the operation unit 120. For example, when the user uses the portable terminal device 100 with his / her ear on the ear, the input invalidation unit detects the change in the form not intended by the user, the touch panel 105, and the operation unit. The process of invalidating the input may be executed by prohibiting the input from 120 from being input to the control unit 220.

  For example, in the embodiments of the present invention, the portable terminal device that can slide is described as an example. However, the portable terminal device in which the first casing and the second casing can rotate, the first casing and the second casing, and the like. The portable terminal device which can fold a housing | casing may be sufficient.
