The speaker 12 and the earphone jack 13 are means for outputting sound in the mobile terminal 10. When the earphone is inserted into the earphone jack 13, sound data is output to the earphone via the earphone jack 13 (the sound itself is output from the earphone). When no earphone is inserted into the earphone jack 13, sound is output from the speaker 12.

  The mobile terminal 10 includes a camera 14 that is provided on the main surface and is an imaging unit that performs imaging. The mobile terminal 10 includes a power button 15, a volume control button 16, and a camera shooting button 17 as hard keys that are physical buttons for operating the mobile terminal 10. These buttons 15 to 17 are provided on the side surface of the mobile terminal 10 with respect to the main surface. The power button 15 is a button for turning on / off the power of the mobile terminal 10. When the power button 15 is pressed for a long time (the pressed state continues for a preset time or longer and then the pressed state ends), the power of the mobile terminal 10 is turned on / off (in the on state, off, off If it is in the state, it is turned on, and so on. When the power button 15 is pressed for a short time (less than a preset time, the pressed state continues after the pressed state continues), the power of the touch panel 11 is turned on / off (the backlight of the touch panel 11 (display) is turned on / off). Is called. The volume control button 16 is a button for raising and lowering the volume of the audio output output from the mobile terminal 10. The volume control button 16 can be pressed in either the direction of increasing or the direction of decreasing the volume. For example, the volume is increased when the upper side of the volume adjustment button 16 shown in FIG. 1 is pressed, and the volume is reduced when the lower side of the volume adjustment button 16 shown in FIG. 1 is pressed. The camera shooting button 17 is a button for taking an image with the camera 14, and when pressed, the image is taken.

  The portable terminal 10 includes a sensor for detecting a physical state of the terminal 10 such as a speed sensor, an acceleration sensor, and a gyro sensor.

  Subsequently, functions of the mobile terminal 10 according to the present invention will be described. As illustrated in FIG. 2, the mobile terminal 10 includes a touch panel 11, a state detection unit 21, a walking determination unit 22, a camera 14, and a control unit 23. In addition to the above functions, the mobile terminal 10 may have functions such as a mobile communication function that are normally provided in a device such as a smartphone.

  The touch panel 11 is display means for displaying information on the display screen as described above. Specifically, for example, the touch panel 11 inputs information to be displayed on the display screen from an application executed in the mobile terminal 10 in response to a user operation, and displays the information. The application that inputs information to be displayed on the touch panel 11 is an application that reproduces music data (audio data), for example. The information displayed on the touch panel 11 is, for example, information on the music to be played (song name, singer name, etc.). The touch panel 11 displays a user interface for the user to operate the application. Specifically, buttons such as music playback and end, music feed, music return, volume up, and volume down are displayed.

  The touch panel 11 detects (detects) a contact (touch) on the display screen and accepts an operation (touch operation) on the terminal 10 due to the contact. For example, the touch panel 11 detects a change in capacitance caused by a user's finger or the like touching the display screen, and inputs an operation based on these changes. The touch panel 11 detects a position where a user's finger or the like is touched on the display screen, and inputs an operation at the position. Specifically, the information indicating the position where the user's finger or the like is touched is, for example, coordinates of the display screen of the touch panel 11 (position on the coordinate axis). In the mobile terminal 10, an operation corresponding to the input operation is performed.

  Specifically, when the user touches a portion of the user interface displayed on the touch panel 11 for operating the application, an operation corresponding to the portion is performed. As described above, when the button is touched, the operation corresponding to the button is performed.

  The state detection unit 21 is a state detection unit that detects the physical state of the terminal 10 itself. The physical state of the terminal 10 detected by the state detector 21 is for determining whether or not the user carrying the mobile terminal 10 is walking. Specifically, the state detection unit 21 detects the speed, acceleration, or posture of the terminal 10 as the physical state of the terminal 10. The state detection unit 21 performs the above detection using sensors such as a speed sensor, an acceleration sensor, and a gyro sensor included in the mobile terminal 10. The speed of the terminal 10 is measured by the speed sensor, and the acceleration of the terminal 10 by the acceleration sensor is the attitude of the terminal 10 by the gyro sensor (the state of the terminal 10 is up, down, left, and right. ) Are detected. In addition, what was used conventionally can be used for each said sensor. In addition, as long as the user's walking can be determined, it is not necessary that all the sensors described above are provided in the mobile terminal 10, and any sensor may be provided. In addition, sensors other than those described above may be used as long as the user's walking can be determined.

  The state detection unit 21 detects the above state in real time, for example. Or the state detection part 21 is good also as detecting said state for every fixed time (for example, every several seconds). In addition, the state detection unit 21 detects the above state only when the function of the present embodiment is necessary (for example, when the browser is activated and information input from the browser is displayed on the touch panel 11). You may do it. The state detection unit 21 outputs information indicating the detected state of the terminal 10 to the walking determination unit 22.

  The walking determination unit 22 is a walking determination unit that determines whether the user carrying the terminal 10 is walking based on the state detected by the state detection unit 21. Determination of a user's walk by the walk determination part 22 may be performed similarly to the conventional technique. For example, the walking determination unit 22 stores in advance a state indicating the state of the terminal 10 when the user is walking, and indicates the state indicated by the information input from the state detection unit 21 and the stored state. Judgment is made by comparison. When it is determined that the state indicated by the information input from the state detection unit 21 matches or is similar to the stored state as a result of the comparison, the walking determination unit 22 is walking. Is determined. The walking determination unit 22 notifies the control unit 23 of the determination result.

  The camera 14 is an imaging unit that performs imaging as described above. The camera 14 performs time-series imaging. The image obtained by imaging with the camera 14 is for determining whether or not the terminal 10 is held in the user's hand. The camera 14 performs imaging in real time, for example. Alternatively, the camera 14 may capture an image every certain time (for example, every few seconds). Further, the state detection unit 21 may perform imaging only when the function of the present embodiment is necessary. The camera 14 outputs an image obtained by imaging to the control unit 23.

  The control unit 23 is a control unit that sets the operation of the terminal 10 according to the operation received by the touch panel 11 in accordance with the determination by the walking determination unit 22. Specifically, the control unit 23 sets the operation of the own terminal 10 according to the operation received by the touch panel 11 when receiving a notification that the user is walking from the walking determination unit 22. To do.

  The control unit 23 sets an area obtained by dividing the entire display screen of the touch panel 11. For example, five areas 11a to 11e are set as shown in FIG. This region is a region 11a to 11d along any one of the sides of the rectangular touch panel 11 with rounded corners, and a central rectangular region 11e. The control unit 23 performs control so that the functions associated with the regions 11a to 11e are executed when the regions 11a to 11e are touched (touched). As described above, when the user is walking, the control unit 23 performs input (operation) on the input mode of the terminal 10 using the areas 11a to 11e obtained by dividing the display screen of the touch panel 11 into five. Change to the 5 pattern mode which is the input mode.

  For example, when touching the region 11a (the “1 (upper)” region shown in FIG. 3, the same applies hereinafter), the control unit 23 performs control so as to execute an operation (function) for increasing the volume. When the area 11c (“3 (lower part)”) is touched, the control unit 23 performs control so as to execute the function of volume reduction. When the area 11b (“2 (right side)”) is touched, the control unit 23 performs control so as to execute the music feeding operation. When the area 11d (“4 (left side)”) is touched, the control unit 23 performs control so as to perform a music return operation. When the area 11e (“5 (center)”) is touched, the control unit 23 performs an operation of playing or stopping the music (playing back if stopped, and stopping if playing) Control to run. Note that the operation allocation corresponding to the areas 11a to 11e is set in the mobile terminal 10 in advance by the user or the manufacturer of the mobile terminal 10 or the like.

  This setting allows the user to perform an operation without referring to the user interface displayed on the touch panel 11 for performing the operation. Further, this setting is different from the user interface for performing the operation displayed on the touch panel 11 when no walking is detected.

  Further, the control unit 23 may set the operation of the own terminal 10 according to the operation received by the touch panel 11 according to the posture of the own terminal 10 detected by the state detection unit 21. In this case, for example, the posture of the terminal 10 is detected by the state detection unit 21 (for example, a gyro sensor). Based on this posture, the control unit 23 determines an area that is above the ground among the five areas of the touch panel 11 and sets the area as a “1 (upper)” area. In this way, by setting the operation of the own terminal 10 according to the attitude of the own terminal 10, even when the user cannot grasp the attitude of the own terminal 10, the user can appropriately perform the operation. Can do. In this case, the posture of the terminal 10 detected by the state detection unit 21 may or may not be used for determining the user's walking.

  The control unit 23 may set the operation of the own terminal 10 according to the operation received by the touch panel 11 and prohibit display (invalidate display) by the touch panel 11. For example, the control unit 23 may perform control to turn off the backlight of the touch panel 11 (turn off the display).

  The above-described control of the control unit 23 is to prevent the user from walking while holding the mobile terminal 10 and watching the display of the mobile terminal 10. Therefore, when the mobile terminal 10 is held in the user's hand and is not operated (for example, when the mobile terminal 10 is in a bag held by the user), the above control is not necessarily effective. There is. Therefore, the control unit 23 may determine whether or not the terminal 10 is held in the user's hand based on a time-series image obtained by time-series imaging with the camera 14. This determination may be performed in the same manner as in the conventional technique. For example, if there is a temporal change between a plurality of images (videos) obtained by imaging, it is determined that the terminal 10 is held in the user's hand. If there is no such change, it is determined that the terminal 10 is not held in the user's hand.

  Control part 23 sets operation of self-terminal 10 according to operation accepted by touch panel 11 according to the judgment. The control unit 23 performs the above control only when it is determined that the own terminal 10 is held in the user's hand. That is, the control unit 23 performs the above-described control when it is determined that the user is walking and the terminal 10 is held in the user's hand. Even if it is determined that the user is walking, the control unit 23 does not perform the above control if it is determined that the terminal 10 is not held in the user's hand.

  Further, when a specific button (for example, the power button 15) is pressed, the control unit 23 ends the five pattern mode, and the original input mode (the normal input mode corresponding to the application being executed in the mobile terminal 10). ). Further, when the control for prohibiting the display by the touch panel 11 is performed, the control unit 23 may perform the control for displaying the touch panel 11 together with the end of the five pattern mode.

  The control unit 23 does not perform any special control when receiving a notification from the walking determination unit 22 that it is determined that the user is not walking. That is, in this case, the mobile terminal 10 performs the same operation as that of a normal smartphone or the like. Further, when the user stops walking while the five pattern mode is set, the control unit 23 may end the five pattern mode and return to the original input mode.

  Subsequently, FIG. 4 shows a hardware configuration of the mobile terminal 10 according to the present embodiment. As shown in FIG. 4, the mobile terminal 10 includes hardware such as a CPU (Central Processing Unit) 101, a RAM (Random Access Memory) 102, a ROM (Read Only Memory) 103, a mobile communication module 104, an antenna 105, and the like. ing. The mobile terminal 10 includes a touch panel 11, a sensor 106, a speaker 12, a camera 14, and an operation module 107 as hardware. The sensor 106 corresponds to the above-described speed sensor, acceleration sensor, and gyro sensor. The operation module 107 corresponds to the power button 15, the volume adjustment button 16, and the camera shooting button 17 described above. The functions described above are exhibited when these components are operated by a program or the like. The above is the configuration of the mobile terminal 10.

  Subsequently, a control method that is a process (an operation method of the mobile terminal 10) executed by the mobile terminal 10 that is the terminal according to the present embodiment will be described using the flowchart of FIG. Prior to this processing, an application for playing back music data is activated on the mobile terminal 10, and a touch operation by a user interface corresponding to the application can be performed on the touch panel 11.

  In this process, first, the physical state of the terminal 10 is detected by the state detection unit 21 (S01, state detection step). The detected state is, for example, the speed, acceleration, or posture of the terminal 10 itself. Information indicating the detected state of the terminal 10 is input from the state detection unit 21 to the walking determination unit 22. Subsequently, the walking determination unit 22 determines whether or not the user carrying the terminal 10 is walking based on the state detected by the state detection unit 21 (S02, walking determination step). The determination result is notified from the walking determination unit 22 to the control unit 23.

  When it is determined that the user carrying the terminal 10 is not walking (NO in S02), control by the control unit 23 is not performed, and normal operation is performed (S03).

  When it is determined that the user carrying the terminal 10 is not walking (YES in S02), the control by the control unit 23 is performed as follows. First, under the control of the control unit 23, the backlight of the touch panel 11 (display) is turned off (display disabled) (S04, control step). In addition to this processing, the control unit 23 sets the operation of the terminal 10 according to the operation received by the touch panel 11. Specifically, the input mode is changed to a 5-pattern mode as shown in FIG. 3 (S05, control step).

  Here, when the user of the mobile terminal 10 performs an operation by touch (touch operation) on the display screen of the touch panel 11, the operation is received by the touch panel 11 (S06, operation reception step). In the portable terminal 10, control by the control unit 23 is performed based on the five pattern mode so that an operation corresponding to the touch operation is performed (S07, control step). This operation corresponds to the application being executed on the mobile terminal 10 as described above. For example, as described above, when the area 11a shown in FIG. 3 is touched, the control unit 23 controls the sound volume up operation (function) to be executed.

  The operation according to the acceptance of the touch operation and the touch operation in the 5-pattern mode (the processes of S06 and S07) is repeatedly performed until the 5-pattern mode is completed.

  The operation setting of the own terminal 10 according to the operation accepted by the touch panel 11 (assignment of which region in the five pattern modes performs which operation) (S04) is determined by the own terminal detected by the state detection unit 21. It is good also as performing according to 10 attitude | positions. Further, based on the image captured by the camera 14, it is determined whether or not the portable terminal 10 is held in the user's hand, and the change to the five-pattern mode is performed in accordance with the determination. Also good.

  When the power button 15 is pressed during the 5 pattern mode and during the change to the 5 pattern mode (S04 to S07), the backlight of the touch panel 11 (display) is turned on by the control of the control unit 23. At the same time, the five pattern mode may be terminated and the original input mode may be restored. When the user is not walking during the five pattern mode, the five pattern mode may be ended by the control of the control unit 23 and the original input mode may be returned. The above is the process executed on the mobile terminal 10.

  As described above, according to the present embodiment, when it is determined that the user is walking, for example, the mobile terminal 10 according to an operation by touching the touch panel 11 as in the above-described five pattern mode. The action is set. If the user does not need to look at the display screen, the user can carry out the operation without looking at the display screen when the user carrying the mobile terminal 10 is walking. Thereby, it is possible to prevent the attention to the surroundings from being distracted during walking, and to reduce collision accidents and the like. Therefore, according to the present embodiment, dangerous use of the mobile terminal 10 can be prevented. That is, according to the present embodiment, it is possible to reduce the risk of the user who owns the mobile terminal 10, and the user can use the mobile terminal 10 safely. The operation corresponding to the touch operation is not limited to the above-described five pattern mode, and any operation can be performed as long as the user can operate without looking at the display screen.

  Further, as described above, as information for determining the user's walking, for example, the speed, acceleration, or posture of the terminal 10 may be used. According to this configuration, it can be determined whether or not the user is walking. Therefore, according to this structure, the danger of the user who possesses a portable terminal can be reduced reliably. However, if it can be determined that the user is walking, information other than the above may be used.

  Further, as described above, the operation of the mobile terminal 10 according to the operation accepted by the touch panel 11 may be set according to the attitude of the mobile terminal 10. According to this structure, even if it is a case where the user cannot grasp | ascertain the attitude | position of the portable terminal 10, a user can be made to operate appropriately.
