It is a flowchart which shows the processing flow of the portable information terminal which concerns on this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the following description, and can be appropriately changed without departing from the scope of the present invention.

  First, the configuration of the mobile terminal device 100 according to the present invention will be described. Here, FIG. 2 is a block diagram showing a functional configuration of the mobile terminal device 100. As shown in FIG. As shown in this figure, the mobile terminal device 100 includes a pressure sensor unit 40, a control unit 46, a storage unit 44, a touch panel unit 51, and a display unit 54.

  The pressure sensor unit 40 determines from which pressure sensor 41 a plurality of pressure sensors 41 for detecting a pressure value when pressing a finger of the hand holding the main body of the portable terminal device 100 detects the pressure value. A determination circuit 42 is provided.

  The pressure sensor 41 is not limited to a diaphragm gauge that detects the pressure applied to the diaphragm using a change in capacitance or a deformation of a strain gauge, and is a contact detection type pressure switch operated at a constant pressure. It is also good.

  A plurality of pressure sensors 41 are provided at arbitrary positions to which the fingers of the hand holding the main body of the mobile terminal device 100 can reach. In FIG. 3 and FIG. 4, the button shape is provided on the left and right sides of the main body, but the present invention is not limited to this. A thin film is provided on the surface of the main body of the portable terminal 100. It is possible to embed smoothly without unevenness.

  The determination circuit 42 is a circuit that determines which pressure sensor 41 among the pressure sensors 41 provided in the main body of the mobile terminal device 100 detects a pressure value.

  The control unit 46 includes a CPU, a ROM, a RAM, and the like, and executes various programs such as an operation system and programs necessary for the operation of the present invention. The CPU calls a program or data stored in the ROM, the storage unit 44 or the like to the RAM, and executes the process. The ROM is a non-volatile memory, and programs and data are permanently stored. The RAM is a volatile memory, and temporarily stores programs and data read from the ROM, the storage unit 44 and the like.

  The control unit 46 counts at least the time when the pressure sensor 41 is pressed. When the pressure value detected by the pressure sensor 41 exceeds the threshold value, the pressure value and the pressure sensor 41 are either Based on whether the screen displayed on the touch screen 110 is moved or reduced based on whether the pressure sensor 41 is based on setting information stored in advance in the storage unit 44. The determination unit 49 determines whether the pressed time has reached the count start time, and the delay control unit 50 holds the state of the screen displayed on the touch screen 110 until the delay end time is reached.

  For calculation of movement or reduction in the calculation unit 48, it is possible to use affine transformation or the like generally known in image processing.

  The storage unit 44 is a flash memory or the like, and stores programs executed by the control unit 46 and information necessary for executing the programs. Further, the storage unit 44 has a first storage unit 45 a in which setting information which can be arbitrarily set in advance is stored, and a second control unit 45 b in which the setting information calculated by the control unit 46 is stored.

  The setting information that can be arbitrarily set in advance starts at least a threshold Fmin for determining whether the pressure value detected by the pressure sensor 41 exceeds a certain value and starts counting the time when the pressure sensor 41 is pressed. Start time Tmin and count end time Tmax for determining whether or not to end time counting, and the time to return to the standard state from the state in which the screen displayed on the touch screen 110 is held is reached. In addition to the delay end time TCmax for determining whether or not the screen has been displayed on the touch screen 110, and the maximum value Emax of the reduction of the screen displayed on the touch screen 110, Contains setting information on the direction in which the screen displayed on touch screen 110 is moved. .

  Here, the setting information related to the reduction amount of the screen displayed on the touch screen 110 can be a scale ratio (percentage). For example, when the screen displayed on the touch screen 110 is reduced to 80%, the reduction amount is 20%. Further, setting information regarding the direction in which the screen displayed on the touch screen 110 is moved can be set in advance for each pressure sensor 41.

  The setting information calculated by the control unit 46 includes the speed at which the screen displayed on the touch screen 110 is moved. This velocity can be calculated using the equation S = k · F (where S, k and F are velocity, constant and pressure, respectively). Further, the range detectable by the pressure sensor 41 is divided in advance stepwise into several ranges, the speed corresponding to each range is set, and it is determined which range the detected pressure value belongs to. The corresponding speed may be calculated by

  The touch panel unit 51 and the display unit 54 constitute a touch screen 110. The touch panel unit 51 corresponds to the input interface of the touch screen 110, and includes a circuit 53 that acquires the coordinate value of the position touched on the touch panel 52. The display unit 54 corresponds to the output interface of the touch screen 110, and includes a display device 55 and a display control unit 56.

  The display control unit 56 performs display processing of the touch screen 110 based on a program or the like executed by the control unit 46, and moves or reduces the screen displayed on the touch screen 110.

  Next, the operation of the portable information terminal 100 in the present invention will be described with reference to FIGS. 3 and 4. FIG.3 and FIG.4 is explanatory drawing regarding operation of the portable terminal device 100 in this invention, and makes a smart phone an example and demonstrates it.

  In FIG. 3A, when the pressure sensor 10 is pressed in the direction of 20 with the thumb not reaching the icon 4 displayed on the upper left of the touch screen 110, the screen displayed on the touch screen 110 is the right end face and the lower side. It is shown moving in the lower right direction 21 while the position of the end face is fixed. Before this operation, the thumb did not reach the icon 4 in the one-hand operation, but after this operation, the thumb can reach the icon 22 even in the one-hand operation, so the operability with one hand can be improved.

  Further, in FIG. 3B, when the pressure sensor 11 is pressed in a state where the thumb does not reach the icon 5 displayed at the lower left of the touch screen 110, the screen displayed on the touch screen 110 has the right end face and the upper end face. It is shown moving in the upper right direction 24 while the position is fixed. Before this operation, the thumb did not reach the icon 5 in the one-hand operation, but after this operation, the thumb can reach the icon 25 even in the one-hand operation, so that the operability with one hand can be improved.

  Further, in FIG. 4A, when the two pressure sensors 10 and 11 are simultaneously pressed in a state where the thumb does not reach the icon 4 displayed on the upper left of the touch screen 110, the screen displayed on the touch screen 110 is the right end. It is shown moving and contracting in the right direction 31 while the position of the surface is fixed. Before this operation, the thumb did not reach the icon 4 in the one-hand operation, but after this operation, the thumb can reach the icon 32 even in the one-hand operation, so the operability with one hand can be improved.

  Also, in FIG. 4B, when the two pressure sensors 10 and 11 are simultaneously pressed in a state where the thumb does not reach the icon 5 displayed at the lower left of the touch screen 110, the screen displayed on the touch screen 110 is the right end. It is shown moving and contracting in the right direction 31 while the position of the surface is fixed. Before this operation, the thumb did not reach the icon 5 in the one-hand operation, but after this operation, the thumb can reach the icon 32 even in the one-hand operation, so the operability with one hand can be improved.

  Here, the pressure sensors 10, 11, 12, 13 can detect pressure values unlike simple switching, so when a large pressure value is detected by pressing the pressure sensors 10, 11, 12, 13 strongly, a touch is generated. The screen displayed on the screen 110 moves or shrinks quickly, and when a small pressure value is detected by weakly pressing the pressure sensors 10, 11, 12, 13, it moves or shrinks slowly. Since these operations can be performed while visually confirming on the touch screen 110, it is intuitively easy to understand and can improve operability.

  When the pressure sensor 10 provided above the left side of the main body of the smartphone 100 is pressed, the screen displayed on the touch screen 110 moves in the lower right direction 21 and the lower side of the left side of the main body The direction 21, 24 in which the screen moves is previously associated with any pressure sensor 10, 11 so that the screen moves in the upper right direction 24 when the pressure sensor 11 provided on the screen is pressed. , The operation becomes intuitive and easy to understand.

  In addition, when two pressure sensors 10 and 11 respectively provided on the upper left side and the lower side of the left side surface of the main body of the smartphone 100 are pressed simultaneously, it becomes close to an operation to grasp a hand. Shrinking the screen displayed on the touch screen 110 by performing this operation is consistent with the experience that if you hold an object, it deforms and shrinks, and the operation becomes intuitive and easy to understand.

  3 and 4, only the operation of the smartphone 100 with the right hand is shown, and the operation with the left hand is not shown. However, when operating with the left hand, the pressure sensor is 12 instead of 10 instead of 12 By relating the direction in which the screen displayed on the touch screen 110 moves to the pressure sensors 12 and 13 in advance so that they can be operated at 13, the same operability as that of the right hand is obtained. It is secured also in the left hand.

  Next, the processing flow of the present invention will be described with reference to FIG. 3, FIG. 4 and FIG. Here, FIG. 5 is a flowchart showing the process flow of the mobile terminal device 100 according to the present invention. In the explanation in FIG. 5, IF statement, ++,! Operators such as =, &&, and || are used.

  In S0, initialization is performed. That is, setting information set in advance, for example, a threshold Fmin for determining whether the pressure value detected by the pressure sensor exceeds a certain value, the pressure sensors 10, 11, 12, 13 are pressed Holds the screen displayed on the touch screen 110, counting start time Tmin and counting end time Tmax for determining whether to start time counting at time T10, 11, 12, 13 and whether to end time counting The delay operation end time TCmax for determining whether or not the time for returning from the state to the standard state has been reached, the maximum value Dmax of the movement amount of the screen displayed on the touch screen 110, and the value displayed on the touch screen 110 The maximum value Emax or the like of the reduction amount of the screen is stored in the first storage unit 45a. Then, it progresses to S2.

  In S1, the movement D of the screen displayed on the touch screen 110, the reduction E, and the times T10, T11, T12, T13 when the pressure sensors 10, 11, 12, 13 are pressed, the timer counter TC, the movement D The flag that determines that the reduction amount E has reached the maximum value is all initialized to 0, and the screen displayed on the touch screen 110 is in the standard state. Hereinafter, T10, T11, T12, and T13 will be representatively described as TXX.

  In S2, it is determined whether the pressure values F10, F11, F12, F13 detected by the pressure sensors 10, 11, 12, 13 exceed the threshold Fmin. Hereinafter, F10, F11, F12, and F13 are represented as FFX as a representative.

  If it is determined in S2 that the pressure value FXX exceeds the threshold Fmin, the process proceeds to S3. Otherwise, the process proceeds to S14.

  In S3, the process of the counter unit 47 is performed. That is, the time TXX in which the pressure sensors 10, 11, 12, 13 are pressed under a constant condition is counted. Here, in the present embodiment, the time TXX is counted because each of the movement amount D and the reduction amount E of the screen displayed on the touch screen 110 has not reached the maximum value Dmax and the maximum value Emax (flag Is not 1) and the time TXX has not reached the count end time Tmax, but this is not necessarily a limitation.

  In S4, the processing of the arithmetic unit 48 is performed. That is, based on the pressure value FFX detected by the pressure sensors 10, 11, 12, 13, the speed SXX for moving or reducing the screen displayed on the touch screen 110 is calculated. The speed SXX calculated here is stored in the second memory circuit 46. Hereinafter, the speeds S10, S11, S12, and S13 are represented as SXX as a representative.

  The velocity SXX can be calculated using the equation SXX = k · FXX (where k is a constant). Further, the range which can be detected by the pressure sensor is divided in advance stepwise into several ranges, the speed SXX corresponding to each range is set, and it is determined by which range the pressure value FXX belongs. The corresponding speed SXX may be calculated.

  At S5, it is determined whether the time TXX counted at S3 has reached the count start time Tmin.

  If it is determined in S5 that only the time T10 during which the pressure sensor 10 is pressed has reached the count start time Tmin, the process proceeds to S6, and the screen displayed on the touch screen 110 is moved at the speed S in the lower right direction. At the same time, the movement amount D is counted up. Then, it progresses to S12.

  If it is determined in S5 that only the time T11 during which the pressure sensor 11 is pressed has reached the count start time Tmin, the process proceeds to S7, and the screen displayed on the touch screen 110 is turned upward at the speed S At the same time, the movement amount D is counted up. Then, it progresses to S12.

  If it is determined in S5 that only time T10 when the pressure sensor 10 is pressed and time T11 when the pressure sensor 11 is pressed have reached the count start time Tmin, the process proceeds to S8 and displayed on the touch screen 110 The reduction screen E is reduced to the right at speed S, and at the same time, the reduction amount E is counted up. Then, it progresses to S12.

  If it is determined in S5 that only the time T12 during which the pressure sensor 12 is pressed has reached the count start time Tmin, the process proceeds to S9, and the screen displayed on the touch screen 110 is moved downward at the speed S At the same time, the movement amount D is counted up. Then, it progresses to S12.

  If it is determined in S5 that only the time T13 during which the pressure sensor 13 is pressed has reached the count start time Tmin, the process proceeds to S10, and the screen displayed on the touch screen 110 is moved upward to the left at a speed S At the same time, the movement amount D is counted up. Then, it progresses to S12.

  If it is determined in S5 that only the time T12 when the pressure sensor 12 is pressed and the time T13 when the pressure sensor 13 is pressed have reached the count start time Tmin, the process proceeds to S11 and displayed on the touch screen 110 The reduction screen E is reduced to the right at speed S, and at the same time, the reduction amount E is counted up. Then, it progresses to S12.

  If it is determined in S5 that none of the times TXX during which the pressure sensors 10, 11, 12, 13 are pressed has reached the count start time Tmin, the process returns to S2.

  In the above-described S6, S7, S9, and S10, the processing of the display control unit 56 is performed, and the screen displayed on the touch screen 110 moves or reduces.

  Further, in the above S6, S7, S9 and S10, the movement amount of the screen displayed on the touch screen 110 is counted up, but the direction in which the screen moves is set in advance for each pressure sensor. In FIG. 3, the moving direction is set to move in the diagonal direction of the touch screen 110 from the position of the pressure sensors 10, 11, 12, 13.

  Further, in S8 and S11, the reduction amount of the screen displayed on the touch screen 110 is counted up, but the direction in which the screen is reduced is determined by the movement direction set in at least two pressure sensors. In FIG. 4, when the pressure sensors 10 and 11 are simultaneously pressed, the position of the right end of the screen is reduced while being fixed. Further, although not shown, when the pressure sensors 12 and 13 are simultaneously pressed, the position of the left end of the screen is reduced while being fixed.

  In S12, the movement amount D of the screen displayed on the touch screen 110 has reached a preset maximum value Dmax, or the reduction amount E of the screen displayed on the touch screen 110 has a preset maximum value It is determined whether Emax has been reached.

  If the movement amount D has not reached the maximum value Dmax or the reduction amount E has not reached the maximum value Emax in S12, the process returns to S2. Otherwise, the flag is set to 1 in S13, and the process returns to S2.

  In S14, the process of the determination unit 49 is performed. That is, it is determined whether or not the time TXX when the pressure sensors 10, 11, 12, 13 are pressed has reached the count start time Tmin. If it is determined in S14 that the time TXX has reached the count start time Tmin, the process proceeds to S15, and the loop process from S15 to S17 is performed. If the time TXX has not reached the count start time Tmin, the process returns to S1 to immediately restore the screen displayed on the touch screen to the standard state.

  In the loop process from S15 to S17, the process of the delay control unit 50 is performed. For example, assuming that the operating clock frequency is 1 KHz or 1 step is 1 millisecond and threshold TCmax is 5000 or 5 seconds, timer counter TC is incremented by 1 in 1 millisecond steps and touch screen 110 for 5000 times or 5 seconds. The state of the displayed screen is held.

  In S15, the pressure value FXX is compared with the threshold value Fmin to determine whether or not the pressure value has been pressed. If it is determined that the pressure value FXX exceeds the threshold value Fmin, the delay operation is ended, and the process proceeds to S1. Otherwise, the process proceeds to S16.

  At S16, the timer counter TC is counted up, and the process proceeds to S17.

  At S17, it is determined whether the timer counter TC has reached the delay operation end time TCmax. If it is determined that the timer counter TC has reached the delay operation end TCmax, the process returns to S1 in order to restore the screen displayed on the touch screen 110 from the holding state to the standard state. If it is determined that the timer counter TC has not reached the delay operation end TCmax, the process returns to S15 while the state of the screen displayed on the touch screen 110 is maintained.

  As described above, according to the process shown in FIG. 5, if the user continues pressing the pressure sensors 10, 11, 12, 13 during the preset count start time Tmin or more and the count end time Tmin or less, the touch screen 110 is displayed. The screen may be moved or reduced.

  Further, according to the process shown in FIG. 5, when the user presses the pressure sensor for one touch, the pressure value FXX is determined to be equal to or less than the threshold Fmin in S2, and the pressure sensors 10, 11, 12, 13 are pressed in S14. If it is determined that the time period TXX has not reached the count start time Tmin, the screen displayed on the touch screen 110 can be immediately returned to the standard state. That is, if the user's operation on the pressure sensors 10, 11, 12, 13 is as light as one touch, there is no intention to move or reduce the screen displayed on the touch screen 110. You can return to the screen.

  Further, according to the process shown in FIG. 5, when the user releases the finger pressing the pressure sensor 10, 11, 12, 13, the time TXX during which the pressure sensor 10, 11, 12, 13 is pressed in S14 is If it is determined that the count start time Tmin has been reached, the loop processing from S15 to S17 holds the state of the screen displayed on the touch screen 110 until the delay end time TCmax is reached, and the screen in the standard state is displayed. You can delay the return. That is, even if the user releases the finger pressing the pressure sensor 10, 11, 12, 13, even when the operation on the pressure sensor 10, 11, 12, 13 of the user is performed for the count start time Tmin or more, the touch is still performed. Assuming that the screen displayed on the screen 110 is to be moved or reduced, the screen displayed on the touch screen 110 is held until the delay end time TCmax is reached, and then the screen in the standard state is restored. be able to.

  In addition, while the state of the screen displayed on the touch screen 110 is maintained until the delay end time TCmax elapses, that is, the screen is immediately returned to the standard state during the loop processing from S15 to S17. If it is desired, one of the pressure sensors is pressed by one touch with a force exceeding a certain level, and if it is determined in S15 that the pressure value FXX exceeds the threshold Fmin, the screen can be returned to the standard state immediately. .

  Therefore, if the loop processing from S15 to S17 is implemented, the state of the screen displayed on the touch screen 110 is held until the delay end time TCmax is reached after the user removes the finger from the pressure sensor. Since it is easy for the user to simultaneously perform both the operation on the pressure sensors 10, 11, 12, and 13 and the touch operation on icons and buttons displayed on the touch screen, operability is improved. Can.

  Further, according to the process shown in FIG. 5, it is determined in S2 whether or not the pressure sensors 10, 11, 12, 13 are pressed by the pressure exceeding the threshold Fmin. It can be made inoperable when touching 13 or the like.

  Further, according to the process shown in FIG. 5, it is determined whether or not the time TXX at which the pressure sensors 10, 11, 12, 13 are pressed reaches the count start time Tmin in S14. It can be made inoperable when 10, 11, 12, 13 is touched.

  Further, according to the process shown in FIG. 5, when the time TXX in which the pressure sensor is pressed is counted in S3, the movement amount of the screen displayed on the touch screen 110 or the like on the basis of preset setting information Good operation can be performed by setting a certain limit on the time during which the pressure sensor is pressed in addition to the reduction amount.

  In the normal state, according to the process shown in FIG. 5, the pressure value FXX detected from the pressure sensor is equal to or less than the threshold Fmin, and the time TXX during which the pressure sensor is pressed is also zero. Then, the process of returning to S1 is repeated, and the screen displayed on the touch screen 110 can be maintained in the standard state.

  As described above, according to the embodiment of the present invention, even with the portable information device 100 having the large-sized touch screen 110, moving or reducing the screen displayed on the touch screen while pressing the pressure sensor 41. Thus, it is possible to directly touch an icon or a button displayed on the touch screen 110 while holding it with one hand, so that the operability with one hand can be improved.

  Further, according to the embodiment of the present invention, when the pressure sensor 41 is strongly pressed, the screen displayed on the touch screen 110 is moved or reduced quickly, and when pressed weakly, the screen is moved or reduced slowly. Intuitive operability can be improved while visually confirming movement or reduction of the screen displayed on the screen.

  The present invention can be applied to a portable information terminal having a touch screen, such as a mobile phone, a tablet, an electronic book, etc., as well as a smartphone.

  The present invention is not limited to the embodiments described in the specification, and including other examples and modifications can be understood by those skilled in the art to which the present invention belongs from the embodiments and ideas described herein. It is clear to you.

A display control unit that displays the screen of the touch screen based on the determination in the control unit and the setting information stored in the storage unit;
And the like.

The setting information calculated by the control unit 46 includes the speed at which the screen displayed on the touch screen 110 is moved or reduced . This velocity can be calculated using the equation S = k · F (where S, k and F are velocity, constant and pressure, respectively). Further, the range detectable by the pressure sensor 41 is divided in advance stepwise into several ranges, the speed corresponding to each range is set, and it is determined which range the detected pressure value belongs to. The corresponding speed may be calculated by

As described above, according to the process shown in FIG. 5, the user continues pressing the pressure sensors 10, 11, 12, and 13 with a force exceeding the threshold Fmin, and the time reaches the count start time Tmin and then reaches the count end time Tmax. until, it can be moved or reducing the screen displayed on the touch screen 110.

Further, according to the process shown in FIG. 5, when the user releases the finger pressing the pressure sensor 10, 11, 12, 13, the time TXX during which the pressure sensor 10, 11, 12, 13 is pressed in S14 is If it is determined that the count start time Tmin has been reached , the screen displayed on the touch screen 110 is kept moved or contracted until the delay end time TCmax is reached by loop processing from S15 to S17. Can be delayed to return to the normal state screen. That is, even if the user releases the finger pressing the pressure sensor 10, 11, 12, 13 when the time during which the pressure sensor 10, 11, 12, 13 is pressed has reached the count start time Tmin, as a situation where we want to use a mobile or reduction of the screen displayed yet on the touch screen 110, until it reaches the delay end time TCmax, maintaining the state of the screen displayed on the touch screen 110 has been moved or reduced Afterward, the screen can be returned to the standard state.

Moreover, not elapsed delay end time TCmax, even when the screen displayed on the touch screen 110 is held in a state of being moved or reduced, i.e., in the middle of the loop from S15 to S17, the When it is desired to immediately return the screen to the standard state, one of the pressure sensors is pressed by one touch with a force exceeding a certain degree, and if it is determined in S15 that the pressure value FXX exceeds the threshold Fmin, the standard state is immediately established. You can return to the screen of.

Therefore, if the loop processing from S15 to S17 described above is implemented, the screen displayed on the touch screen 110 is moved or reduced until the delay end time TCmax is reached after the user removes the finger from the pressure sensor . Since it is easy to simultaneously hold both the operation on the pressure sensors 10, 11, 12, and 13 and the touch operation on icons and buttons displayed on the touch screen, the operability can be maintained. Can be improved.
