(Embodiment 1)

The first embodiment of the present invention will be described below with reference to FIGS.
This embodiment exemplifies a case where the present invention is applied to a mobile phone as a terminal device, and FIG. 1 is a block diagram showing basic components of the mobile phone.
A mobile phone is provided with a voice call function, an e-mail function, an Internet connection function (Web access function), and the like. The control unit 1 operates by supplying power from the power supply unit 2 including a secondary battery, and controls the overall operation of the terminal device according to various programs in the storage unit 3. Are provided with a CPU (Central Processing Unit) and a memory.

  The storage unit 3 is an internal memory such as a ROM or a RAM, and has a program area and a data area. The program area implements the present embodiment in accordance with operation procedures shown in FIGS. 4 and 5 described later. A program is stored for this purpose. The data area of the storage unit 3 includes flag information (determined flag F1, touch non-operation flag F2, etc., described later), timer information (determination timer JT, described later), counter information (detection count counter NC, described later). In addition, various information necessary for the operation of the mobile phone is temporarily stored.

  The operation unit 4 includes various push button type keys such as a cross key (decision key and cursor key), numerical keys, and character keys, and performs dial input, character input, command input, and the like. As processing according to the operation signal from the operation unit 4, for example, various processing such as transmission processing and e-mail creation processing is performed. The communication unit 5 is a component of the voice call function, and includes a radio unit, a baseband unit, a demultiplexing unit, and the like. In the operation of the call function, the signal is taken in from the receiving side of the baseband unit and demodulated into a received baseband signal, and then the voice is output from the calling speaker SP via the telephone unit 6, or The input voice data from the call microphone MC is captured from the telephone unit 6 and encoded into a transmission baseband signal, which is then given to the transmission side of the baseband unit and transmitted from the antenna AT.

  The display unit 7 uses, for example, a high-definition liquid crystal or an organic EL, and displays a standby image. A transparent touch sensor 8 is disposed over the entire surface of the display unit 7. . Thus, the touch screen TS is configured by stacking the transparent touch sensor 8 on the surface of the display unit 7. The touch screen TS is configured to include a capacitive touch sensor 8 that detects contact with a human body, and various touch keys are arranged to perform character input, command input, and the like. The control unit 1 executes processing according to a touch input signal from the touch screen TS. Further, the touch screen TS is a rectangular input display area formed on substantially the entire surface except for the peripheral edge of the surface of the casing of the mobile phone. The clock unit 9 measures the current date and time, and the control unit 1 updates the current date and time as the previous touch operation date and time when the previous touch operation was performed every time any touch operation is performed.

  The acceleration sensor 10 detects vibration (acceleration) applied to the mobile phone, 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 applied to the mobile phone as a vibration waveform signal. At that time, the vibration waveform signal output from the acceleration sensor 10 is amplified and the noise component is removed. The control unit 1 detects the vibration applied to the mobile phone during the touch operation on the touch screen TS as acceleration in a direction rotating around the X axis and Y axis of the mobile phone by the acceleration sensor 10. It is determined whether the telephone is held with one hand or both hands. The touch sensor 11 will be described in a second embodiment described later.

  The mobile phone configured as described above has a display unit housing including the display unit 7 and an operation unit housing including the operation unit 4, and the operation unit housing and the display unit housing can be opened and closed (folded). The display unit casing is attached to the operation unit casing so that the front and back sides thereof can be reversed. This two-axis hinge type mobile phone has an open style in which the display unit 7 and the operation unit 4 are exposed in a state where the display unit housing is folded, and a state in which the display unit housing is folded and closed. It has a view style in which the display unit 7 is exposed and the operation unit 4 is hidden.

FIG. 2 is a diagram illustrating acceleration in the direction of rotation about the X-axis and Y-axis detected by the acceleration sensor 10 as vibration applied to the mobile phone during a touch operation on the touch screen TS. In the illustrated example, the case where the mobile phone is set to the view style is shown.
Each time the acceleration sensor 10 detects acceleration in the direction of rotation about the X-axis and Y-axis, the number of detections is counted by the above-described detection number counter NC. This detection counter NC is an acceleration (vibration caused by a touch operation) equal to or greater than a predetermined value until the above-described determination timer JT that measures a predetermined time (for example, 2 seconds) times out (for example, until 2 seconds elapses) When the value of the detection number counter NC is greater than or equal to a predetermined value, that is, because the mobile phone is held in an unstable state, When the vibration due to the touch operation (for example, two touch operations) is increased, it is determined that the mobile phone is held with one hand, but the value of the detection number counter NC is less than a predetermined value. In other words, if the mobile phone is held in a stable state and there is little vibration due to the touch operation (for example, two touch operations) performed within the predetermined time described above, Phone is so determined to have been given by both hands.

  Thus, based on the detection result from the acceleration sensor 10 (acceleration in the direction of rotation around the X-axis and Y-axis axes), the control unit 1 determines how to hold the mobile phone, and touches according to the holding method. A touch invalidation area is secured in a part of the screen TS. This touch invalidation area is an area specially reserved for invalidating a touch operation on the touch screen TS (such as when a finger is inadvertently placed). Note that a detection number counter that measures acceleration in the direction of rotation around the X axis and a detection number counter that measures acceleration in the direction of rotation around the Y axis may be provided separately. In this embodiment, the total value is counted by a single counter without dividing the X axis and the Y axis.

FIG. 3 is a diagram for explaining a state in which a touch invalidation area is secured in a part of the touch screen TS when the mobile phone is held with one hand in a state where the mobile phone is in the view style.
FIG. 3 (1) shows a state where a view-style mobile phone is held with one hand, and the thumb is placed on (touched) a part of the touch screen TS. FIG. 3 (2) shows a touch invalidation area TI secured in a part of the touch screen TS when it is determined that the mobile phone is held with one hand, and the finger is likely to touch when holding the hand with one hand. As a region, the lower end portion of the touch screen TS is secured as a touch invalidation region TI, and a safe region that does not become a touch even when a finger is placed is secured.

  FIG. 3 (3) shows a state in which a view-style mobile phone is held with one hand as in FIG. 3 (1), but a plurality of operation buttons (touch keys) are provided on the touch screen TS. It is arranged in a matrix. Here, as shown in the figure, the areas from the first line (the top row) to the third and fifth lines are areas where operation buttons are arranged, but the area of the fourth line is the operation button. It is a blank area (non-display part) where is not arranged. FIG. 3 (4) shows the touch invalidation area TI secured in a part of the touch screen TS when it is determined that the mobile phone is held with one hand, and the operation button arrangement area in the fifth line is shown in four lines. By scrolling to the blank area (non-display part) of the eye, the area on the fifth line is secured as the touch invalidation area TI, and a safe area that cannot be touched even if the finger is placed is secured.

  Next, the operation concept of the mobile phone according to the first 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. The same applies to other embodiments described later. In addition to the recording medium, an operation peculiar to the present embodiment can be executed using a program / data supplied externally via a transmission medium.

FIG. 4 is a flowchart for explaining the operation of the mobile phone (characteristic operation of the present embodiment) that is started when the power is turned on.
First, the control unit 1 performs an initial setting such as clearing a predetermined memory in response to a power-on operation, and then enters a standby state for some operation or incoming call (step A1 in FIG. 4). In this state, it is checked whether an incoming call is detected (step A2), whether a push button type key on the operation unit 4 or any key on the touch screen TS is operated (step A9), It is checked whether a predetermined time (for example, 10 seconds) has elapsed since the previous touch key operation (whether the touch non-operation time is equal to or longer than the predetermined time) (step A17).

  If an incoming call is detected (YES in step A2), it is checked whether a response operation (off-hook operation) has been performed (step A3), and the line connection is blocked from the communication partner without performing the off-hook operation. If it is performed (NO in step A3), the process returns to step A2, but if an off-hook operation is performed (YES in step A3), it is checked whether a part of the touch screen TS is secured as the touch invalidation area TI (step S3). A4). Here, when the touch invalidation area TI is secured (YES in step A4), the touch screen TS is returned to the original state by releasing the touch invalidation area TI (step A5). Then, after starting the call processing for enabling the call (step A6), it is checked whether an on-hook operation for blocking the line is performed (step A7). When the on-hook operation is performed (YES in step A7), After terminating the call and terminating the call (step A8), the process returns to step A2.

When any key on the operation unit 4 or the touch screen TS is operated (YES in Step A9), it is checked whether a part of the touch screen TS is secured as the touch invalidation area TI (Step A10). Here, when the touch invalidation area TI is secured (YES in Step A10), the touch screen TS is returned to the original state by releasing the touch invalidation area TI (Step A11). Then, as a process according to the operation, for example, after performing a calling process (step A12), it is checked whether the current operation key is a touch key on the touch screen TS (step A13). When the push button type key is operated (NO in step A13), the process returns to the above-described step A2, but when the touch key is operated (YES in step A13),
The previous touch operation date and time is updated by setting the current date and time as the previous touch operation date and time (step A14).

  Then, it is checked whether the determined flag F1 is “0” (step A15). The determined flag F1 indicates whether it is determined whether the mobile phone is held with one hand or both hands during the touch operation on the touch screen TS. The determined flag F1 is “1”. If it has been determined (NO in step A15), the process returns to step A2. If the determined flag F1 is “0” and it is before the determination (YES in step A15), the holding state determination process is executed (step A16).

FIG. 5 is a flowchart for explaining in detail the holding state determination process (step A16 in FIG. 4).
First, the control unit 1 refers to the touch non-operation flag F2 and checks whether the value is “1” (step B1). The touch no-operation flag F2 is “1” when the touch key on the touch screen TS is not operated for a predetermined time (for example, 10 seconds) after the previous operation, and “0” is displayed when the touch key is operated for the first time thereafter. "Is a flag. In other words, the touch non-operation flag F2 is a flag indicating whether or not the first touch operation after the non-operation time has elapsed is performed. If the touch non-operation flag F2 is “1”, it is determined that the touch key is in the non-operation state for a predetermined time (for example, 10 seconds) (YES in step B1), and the acceleration sensor 10 and the determination timer JT are determined. And the detection number counter NC is reset (step B2), the touch no-operation flag F2 is changed from “1” to “0” (step B3), but the touch no-operation flag F2 is “0”. If there is (NO in step B2), the above-mentioned steps B2 and B3 are skipped.

  When the acceleration sensor 10 detects acceleration in the direction of rotation about the X axis or Y axis of the mobile phone during the touch operation on the touch screen TS (YES in step B4), the value of the detection counter NC Is counted up (step B5), and it is checked whether the value of the determination timer JT has reached a predetermined time (for example, 2 seconds) (whether the predetermined time has passed as the touch non-operation time) (step B6). If the time has not passed (NO in step B6), the process leaves the holding state determination process and proceeds to step A2 in FIG. If the predetermined time has not elapsed since the previous touch key operation (NO in step A17 in FIG. 4), it is checked whether the determined flag F1 is “0” (step A15). Since the determined flag F1 is “0” and it is before holding method determination (YES in step A15), the process proceeds to holding method determination process (step A16).

  In this case, since the touch non-operation flag F2 is “0” (NO in step B1 in FIG. 5), the process proceeds to step B4 and is rotated around the X axis or Y axis of the mobile phone by the acceleration sensor 10. Check if direction acceleration is detected. Here, when vibration (acceleration) due to reverberation due to previous touch key operation or instability due to one hand holding is detected (YES in step B4), the value of the detection number counter is incremented (step B5). Then, until the value of the determination timer JT reaches a predetermined time (for example, 2 seconds) (step B6), the process leaves the holding state determination process and proceeds to step A2 in FIG. 4, and thereafter the same operation is repeated. To increment the value of the detection number counter (step B5).

  When the value of the determination timer JT reaches a predetermined time (for example, 2 seconds) (YES in step B6), it is checked whether the detection number counter NC value is equal to or greater than a predetermined value (for example, 10 times) (step B7). . Here, if it is equal to or greater than the predetermined value, that is, if the frequency is high during the touch operation (YES in step B7), it is determined that the mobile phone is held with one hand and the determination result is temporarily stored. (Step B8) If the number of vibrations is small during touch operation and the value of the detection counter NC is less than a predetermined value (NO in Step B7), it is determined that the mobile phone is held with both hands and the determination result is temporarily stored. Store it (step B9). When the holding method is determined in this way, the determined flag F1 is set to "1" (step B10), and then the acceleration sensor 10 and the determination timer JT are stopped and the detection number counter NC is reset (step S10). B11). Then, the process exits from the holding method determination process and proceeds to step A2 in FIG.

  On the other hand, when a predetermined time (touch non-operation time) has elapsed since the previous touch key operation (YES in step A17 in FIG. 4), the touch non-operation flag F2 is set to “1” (step A18), and then The determination result temporarily stored in the holding method determination process is read (step A19), and it is checked whether it is determined that the mobile phone is held with one hand (step A20). As a result, when it is determined that it is held with both hands (NO in step A20), the process returns to the above step A2, but when it is determined that it is held with one hand (YES in step A20), the display of the touch screen TS is displayed. A non-display portion is generated by scrolling the content upward, and this non-display portion is secured as a touch invalidation area TI (step A21). Thereafter, the process returns to step A2.

  As described above, in the first embodiment, the control unit 1 secures the touch invalidation region TI that invalidates the touch operation in a part on the touch screen TS in accordance with how to hold the mobile phone. It is possible to secure a safe area that does not become a touch even if the handset is placed, and it becomes possible to hold the mobile phone stably and to rest the thumb etc. (place the finger). This is useful for viewing e-mails and videos while holding for a long time with one hand.

  When the mobile phone is held with one hand, the touch invalidation area TI is secured on the touch screen TS, so that the mobile phone can be stably held with one hand.

  During the touch operation on the touch screen TS, when acceleration in the direction of rotation around the X-axis and Y-axis of the mobile phone is detected for a predetermined time or more, it is determined that the mobile phone is held with one hand. The acceleration sensor 10 can easily determine whether the mobile phone is held in an unstable state (held with one hand).

When the touch operation on the touch screen TS has not been performed for a predetermined time, the touch invalidation area TI is secured according to how to hold the touch screen TS, so that the touch operation is not performed and the mobile phone is held for a long time with one hand. The touch invalidation area TI can be secured when viewing e-mails or videos.

  When the touch operation on the touch screen TS is resumed, the touch invalidation area TI is canceled and the touch screen TS is returned to the original state. It is possible to return to operation in a wide area.

  Since the operation invalid area TI is secured by scrolling the display content of the touch screen TS in a predetermined direction, a safe area that is not touched even if the finger is placed while the current display state is maintained is secured. be able to.
