  The acceleration sensor 10 detects a vibration state applied to the mobile phone device CP, and is constituted by, for example, a three-axis type acceleration sensor (three-axis direction vibration sensor). In this case, the acceleration sensor 10 outputs the magnitude of acceleration (vibration) applied to the mobile phone device CP as a vibration waveform signal. At this time, the vibration waveform signal output from the acceleration sensor 10 is amplified and the noise component is removed. The CPU 1 acquires the detection result from the acceleration sensor 10 periodically (for example, every 0.5 seconds) and temporarily stores the detection result as the previous detection result, thereby periodically (for example, 0. 0). It is updated every 5 seconds). Then, when a touch on the touch screen TS (touch sensor 8) is detected, the previous detection result of the temporary storage is compared with the current detection result, and if the acceleration change is greater than or equal to a predetermined value, the mobile phone device holds it in the hand.

The in-camera IC described above is used not only for a video phone but also for determining a direction in which the user is facing the touch screen TS, and the CPU 1 uses the in-camera IC. When the user's face is photographed, the face image is analyzed to determine whether the user is facing the touch screen TS.

  The charging device connection unit 12 performs charging using electromagnetic induction between the contactless contactless charging device CG on the power transmission side and the mobile phone device CP on the power receiving side, and charges the mobile phone device CP. Charging is performed by making the device CG approach or connecting (mounting). The CPU 1 periodically acquires the operation state from the charging device connection unit 12 (for example, every 0.5 seconds) and temporarily stores the operation state as the previous operation state, so that the previous operation state is periodically (for example, It is updated every 0.5 seconds. Then, when it is detected that the mobile phone device is held in the hand, the charging start state or the charging end is completed with the charging device CG by comparing the previous operation state of the temporary storage with the current operation state. It is determined whether the state has changed.

Then, when it is detected that the mobile phone device is held in the hand, a communication start state with the non-contact IC unit 14 or a comparison is made between the previous operation state of the temporary storage and the current operation state. It is determined whether or not the communication has ended.

  FIG. 3 shows that the touch operation is temporarily performed even if the finger touches the touch sensor 8 in a specific situation out of the entire area of the touch screen TS formed on substantially the entire surface except the peripheral edge of the surface of the display housing B. It is the figure which showed the specific area to invalidate. 3A is a perspective view showing a view style, and FIG. 3B is a view showing a state in which the mobile phone device CP is held in the view style state. The specific area on the touch screen TS is a hatched area in the figure, and shows the peripheral edge of the entire area of the touch screen TS (the entire display screen). That is, when the mobile phone device CP is held in the hand, the specific area indicates a region where the finger is likely to swing on the touch screen TS, and when the mobile phone device CP is connected to the charging device CG, When the mobile phone device CP is held over the electronic payment machine ST, even when the user does not look at the display screen during the operation of the display application such as video, even if the finger is accidentally swung to a specific area, In such a specific situation, it is provided to invalidate the operation as an unintended touch operation.

  In addition, when the mobile phone device CP is held in the hand, a specific area for temporarily disabling the touch operation is set on the touch screen TS based on whether or not a predetermined situation has changed. . That is, when contactless communication with the electronic payment machine ST is started or ended (when the communication is started or changed), the housing is opened and closed to change the style. In this case, when the charging starts or ends with the charging device CG (when the charging device is changed to the charging start state or the charging end state), the above-described specific area is set. In this case, the touch invalidation in a specific area is a period in which a predetermined situation has changed, and when the change disappears, the specific area returns to a touch valid state. Is invalid.

  Next, the operation concept of the mobile phone device in this embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. Moreover, the operation | movement according to the above-mentioned program code transmitted via transmission media, such as a network, can also be performed sequentially. In other words, in addition to the recording medium, an operation unique to the present embodiment can be executed using a program / data supplied externally via a transmission medium. 4 and 5 are flowcharts showing an outline of the operation of the characteristic part of the present embodiment in the entire operation of the mobile phone device. When the flow of FIG. 4 and FIG. Return to the main flow of operation (not shown).

FIG. 4 is a flowchart showing a touch input process that is started in response to touch detection.
First, when the CPU 1 (see FIG. 1) detects human contact with the touch sensor 8 constituting the touch screen TS, the CPU 1 acquires the touch position coordinates, and temporarily performs a touch operation in the entire area of the touch screen TS. It is checked whether or not the touch is in a specific area to be invalidated (step A1). If the touch operation is outside this specific area (NO in step A1), it is determined that the touch operation is a valid operation. Then, the process proceeds to touch input processing, and a command corresponding to the touch key associated with the touch position is input (step A15).

  If the touch operation is in the above specific area (YES in step A1), the current detection result is acquired from the acceleration sensor 10, and the previous detection result (acceleration) periodically updated as described above. ) And the current detection result and the previous detection result are compared (step A2). As a result, if the acceleration change is greater than or equal to a predetermined value (YES in step A3), it is determined that the mobile phone device is being held by the hand, the process proceeds to step A4, and the operating state of the non-contact IC unit 14 , It is checked whether contactless communication is in progress (electronic money settlement is in progress) (step A5). If non-contact communication is currently being performed (YES in step A5), it is determined that the mobile phone device is held over (closed to) the electronic settlement machine ST, and the current touch operation is invalidated. Therefore, the above touch input process (step A15) is not performed, and this flow is ended.

  Further, when it is determined that the mobile phone device is being held by detecting a change in acceleration of a predetermined value or more as described above (YES in step A3), if it is not in contactless communication ( Further, the operation state of the charging device connection unit 12 is referred to (step A6), and it is checked whether contactless charging is being performed with the contactless charging device CG (step A7). If contactless charging is in progress (YES in step A7), it is determined that the mobile phone device is being held over the charging device CG (a state in which the mobile phone device is approaching), and this touch operation is invalidated. This flow ends without performing the touch input process (step A15) described above.

  On the other hand, if the acceleration change is less than the predetermined value (NO in step A3), it is determined that the mobile phone device is not held, and the process proceeds to step A8 to acquire the current operation state from the charging device connection unit 12. At the same time, as described above, the previous detection result (operating state of the charging device connection unit 12) periodically updated is read, and the previous detection result and the current detection result are compared. As a result, there is a change in the connection state with the charging device CG, that is, the finger touches the mobile phone device even when the acceleration change is less than a predetermined value (even when the mobile phone device is not held in the hand). If the connection state between the mobile phone device and the charging device CG is changed to a disconnected state, it is checked whether the connection state is changed from the disconnected state to the connected (mounted) state (step A9).

  If there is a change in the connection state between the mobile phone device and the charging device CG (YES in step A9), the above touch input process (step A15) is not performed to invalidate the current touch operation. This flow ends. If no change in the charging device connection is detected (NO in step A9), it is checked whether a display application such as a video is operating (step A10). If the display application is not operating (NO in step A10), this time In order to validate the touch operation on the specific area, the process proceeds to touch input processing (step A15).

  If the display application is operating (YES in step A10), the in-camera IC of the imaging unit 11 is activated (step A11), and a captured image obtained by capturing the face of the user who is looking at the display screen (touch screen TS) is displayed. Obtain (step A12). Then, this acquired image is analyzed (step A13), the orientation of the user is determined based on the eyes, nose, eyeballs, and the like, and it is determined whether the user is looking at the display screen (step A14). If the user is looking at the display screen as a result of the image analysis (YES in step A14), the process proceeds to touch input processing in order to validate the touch operation to the specific area this time (step A15). If the display screen is not viewed (NO in step A14), the above-described touch input process (step A15) is not performed to invalidate the current touch operation, and this flow ends.

FIG. 5 is a flowchart illustrating a touch invalidation process started to be executed based on acceleration detection in which the acceleration sensor 10 is accessed to obtain the detection result.
First, the CPU 1 compares the current detection result acquired from the acceleration sensor 10 based on the acceleration detection with the previous detection result that is periodically updated (step B1). It is determined whether it is a change, that is, whether the mobile phone device is held in the hand (step B2). If the acceleration change is not greater than a predetermined value, the flow ends at this point, but the acceleration greater than the predetermined value is reached. If it is a change (YES in step B2), it is determined that the mobile phone device is held in the hand, and the process proceeds to the next step to acquire the current operation state from the charging device connection unit 12 and periodically as described above. The previous detection result (the operating state of the charging device connection unit 12) updated to “1” is read out, and the current detection result is compared with the previous detection result (step B3).

  As a result, it is checked whether the charging device CG has changed to the charging start state or the charging end state, that is, whether the mobile phone device is held by the hand for charging start or charging end (step B4). Now, when a change to the charging start state or the charging end state is detected with the charging device CG (YES in step B4), a specific area where the touch operation can be temporarily disabled on the touch screen TS (See FIG. 3) is set (step B9).

If charging is not started or not completed with the charging device CG (NO in step B4),
With reference to the operation state (detection state) of the style detection unit 13 (step B5), based on the detection result, the CPU 1 has not detected any other style (open style, view style) other than the closed style, That is, it is determined whether or not the style is being changed (step B6). If the style is being changed (YES in step B6), a specific area (in which the touch operation can be temporarily disabled on the touch screen TS) ( (See FIG. 3) is set (step B9).

  If the style is not being changed (NO in step B6), the CPU 1 obtains the current operation state from the non-contact IC unit 14, and the previous detection result (non-contact IC) periodically updated as described above. The operation state of the unit 14 is read out, and the current detection result is compared with the previous detection result (step B7). As a result, it is checked whether a change in non-contact communication has been detected, that is, whether a change has been made to the communication start state or communication end state with the non-contact IC unit 14 (step B8). Now, when the mobile phone device is held by the hand for communication start or communication end (YES in step B8), a specific area (FIG. 3) where the touch operation can be temporarily disabled on the touch screen TS. Reference) is set (step B9). If no change in non-contact communication is detected (step B8), the flow is exited.

  As described above, in this embodiment, the CPU 1 changes the connection state between the mobile phone device CP and the external device (charging device CG) when a touch operation is performed on the touch screen TS (touch sensor 8). Since the touch operation is invalidated when the mobile phone device is held, the mobile phone device and the charging device CG are disconnected or disconnected by touching the touch screen TS even when the mobile phone device is not held in the hand. When the connection is established from the connected state, it is determined that the touch operation is not intended, and the operation can be invalidated to prevent an erroneous operation.

  When a touch operation is performed on the touch screen TS, if the mobile phone device CP is held in the hand and there is a connection relationship with an external device (charging device CG, electronic payment machine ST), the touch operation Since the operation is invalidated, it is assumed that the operation is not intended to be a touch operation during charging or during settlement, and the operation can be invalidated to prevent an erroneous operation.

  Since the external device is a non-contact type electronic device (charging device CG, electronic settlement machine ST), and it is determined that the electronic device is connected to the non-contact type electronic device by detecting the approach to the non-contact type electronic device. Assuming that the touch operation is not intended to be performed close to the contact type electronic device, the operation can be invalidated to prevent an erroneous operation.

  If the change in acceleration is greater than or equal to a predetermined value, it is determined that the mobile phone device is being held by the hand, so it is possible to accurately determine whether the mobile phone is being held by the hand.

  When a touch operation is performed on the touch screen TS, the touch operation is enabled if the user is viewing the display screen, and the touch operation is disabled if the display screen is not visible. Therefore, assuming that the operation is not intended for a touch operation in a state where the user does not visually recognize the display screen, the operation can be invalidated to prevent an erroneous operation.

  Since it is determined whether or not the display application is in a visible state when the display application is operating, it is possible to appropriately determine whether or not the user is looking at the display screen.

  A specific area where the touch operation can be temporarily disabled is provided on the touch screen TS, and whether or not the touch operation is enabled when the touch operation is performed in the specific area is controlled. Thus, for example, even if the peripheral portion of the touch screen TS that is the specific area is touched with a finger, it can be determined that the touch operation in the specific area is not intended.

  When a touch operation is performed on the touch screen TS, if the style is being changed, the touch operation is invalidated. Therefore, it is assumed that the touch operation during the style change is not intended. Can be disabled to prevent erroneous operation.

  Since the touch screen TS is temporarily disabled in response to a change in a predetermined situation while the mobile phone device is held in the hand, an operation that is not intended for a touch operation when the predetermined situation changes If there is, the operation can be disabled to prevent an erroneous operation.

  Whether or not a predetermined situation has changed is determined based on whether or not the charging device CG has changed to a charging start state or a charging end state, and the touch screen TS is temporarily displayed when the charging device has changed to the charging start state or the charging end state. Therefore, it is assumed that the operation is not intended to be a touch operation in the charge start state or the charge end state, and the operation can be invalidated to prevent an erroneous operation.

  The presence or absence of a change in a predetermined situation is determined based on whether or not the communication with the electronic payment machine ST has changed to a communication start state or a communication end state. Since the operation is temporarily invalidated, it is assumed that the touch operation is not intended in the communication start state or the communication end state, and the operation can be invalidated to prevent an erroneous operation.

  The presence / absence of a change in the predetermined situation is determined based on whether or not the style is being changed. If the style is being changed, the touch screen TS is temporarily disabled, so the touch operation during the style change is not intended. As an operation, the operation can be disabled to prevent an erroneous operation.

  In the embodiment described above, the peripheral area of the touch screen TS is set as a specific area for temporarily disabling the touch operation. It may be set arbitrarily according to.

  In the embodiment described above, if the acceleration change is equal to or greater than a predetermined value, it is determined that the mobile phone device is being held by the hand. A touch sensor for grip detection to be detected may be provided on the side of the housing or the like, and it may be determined whether the hand is being held based on the acceleration change and grip detection.

  In the embodiment described above, the present invention is applied to a two-axis hinge type mobile phone device, but it may be of any housing structure such as a folding type, a slide type, a spin top type, and the style includes a closed style and an open style. Although the view style is illustrated, any style according to the housing structure may be used.
