  FIG. 1 is an external view illustrating an external configuration of a mobile terminal 1 according to an embodiment. As illustrated in FIG. 1, the mobile terminal (information terminal) 1 is a communication terminal including a touch panel display 20, and can perform various functions in the mobile terminal 1 by touching the touch panel display 20. it can.

  FIG. 2 is a block diagram illustrating a functional configuration of the mobile terminal 1 according to the embodiment. As shown in FIG. 2, the mobile terminal 1 includes a touch panel display 20 and a control unit 30.

  FIG. 3 is a hardware configuration diagram of the mobile terminal 1. As shown in FIG. 2, the portable terminal 1 is physically exemplified by a CPU (Central Processing Unit) 61, a main storage unit 62 such as a RAM (Random Access Memory) and a ROM (Read Only Memory), a hard disk, a flash memory, and the like. The computer system includes an auxiliary storage unit 63, an input unit 64 such as the detection unit 23, an output unit 65 such as the display screen 21, and the like. The reference point setting unit 31, the operation information acquisition unit 33, and the display control unit 35 included in the control unit 30 described in detail later are predetermined computer software on hardware such as the CPU 61 and the main storage unit 62 shown in FIG. Is executed under the control of the CPU 61. This is realized by operating the input unit 64 and the output unit 65 under the control of the CPU 61 and reading and writing data in the main storage unit 62 and the auxiliary storage unit 63. Again, with reference to FIG. 2, the portable terminal 1 is demonstrated in detail.

  The touch panel display 20 is a part that displays information and detects the presence or absence of a touch (contacted) by a user's finger or the like (including a touch pen) and a touch position (contacted position). The touch panel display 20 includes a display screen 21 that displays information, and a detection unit 23 that detects the presence or absence of a touch and a touch position on the display screen 21.

  The control unit 30 is a part that executes various processes in the mobile terminal 1. The control unit 30 of this embodiment includes a reference point setting unit 31, an operation information acquisition unit 33, and a display control unit 35. The reference point setting unit 31, the operation information acquisition unit 33, and the display control unit 35 are executed under the control of the CPU 61 as described above.

  The reference point setting unit 31 is a part that receives one contacted position detected by the detection unit 23 as a reference point P0 (for example, see FIG. 4) and stores the position of the reference point P0. When receiving one touch position on the display screen 21 by the user as the reference point P0, the reference point setting unit 31 displays a symbol (mark) M (see FIG. 4A) at the position of the reference point P0. The display screen 21 is controlled. Thus, the user can explicitly confirm the position of the reference point P0. The reference point setting unit 31 stores the coordinates (X0, Y0) of the reference point P0.

  The reference point setting unit 31 determines whether the touch operation on the display screen 21 by the user is an input as the reference point P0 based on, for example, the touch time (contacted time) for one point on the display screen 21. ing. For example, when it is detected that a point has been touched for a predetermined time or more, it is determined that the touch operation is an input of the reference point P0.

  The operation information acquisition unit 33 is a part that acquires, as operation information, the movement of the contacted position t detected by the detection unit 23 after the reference point P0 is set. The operation information acquisition unit 33 acquires, as operation information, the movement of the touch position t to the display screen 21 by the user after the reference point P0 is set. The operation information acquired in this way is used for controlling the display screen 21 in the display control unit 35.

  The display control unit 35 is a part that controls the display screen 21 based on a relative change in the contacted position t acquired as operation information with respect to the position of the reference point P0. The display control unit 35 controls the display screen 21 based on a relative change in the coordinates (Xt, Yt) of the touch position t by the user with respect to the coordinates (X0, Y0) of the reference point P0. Hereinafter, an example of the relative change of the coordinate (Xt, Yt) of the touch position t by the user with respect to the coordinate (X0, Y0) of the reference point P0 and an example of the control of the display screen 21 based on the relative change will be described. This will be described in detail with reference to FIGS.

  When the display control unit 35 detects a relative change in which the contact position t as the operation information moves away from the reference point P0, the display content of the display screen 21 is enlarged. Specifically, after one point on the display screen 21 is set as the reference point P0 (see FIG. 4A), the display control unit 35 coordinates the touch position t on the display screen 21 by the user (Xt, When it is detected that Yt) has moved in a direction away from the coordinates (X0, Y0) of the reference point P0, in other words, swept in a direction away from the reference point P0 (see FIG. 4B), the display screen 21 is detected. Magnify the display content of.

  Further, when the display control unit 35 detects a relative change in which the contacted position t as the operation information approaches the reference point P0, the display content on the display screen 21 is reduced. Specifically, after one point on the display screen 21 is set as the reference point P0 (see FIG. 5A), the display control unit 35 coordinates the touch position t on the display screen 21 by the user (Xt, When it is detected that Yt) has moved in the direction approaching the coordinates (X0, Y0) of the reference point P0, in other words, swiped in the direction approaching the reference point P0 (see FIG. 5B), the display screen 21 is detected. Reduce the display content of.

  When the display control unit 35 detects a relative change in which the contacted position t as the operation information moves along the circumferential direction centered on the position of the reference point P0, the display control unit 35 displays the display content of the display screen 21 in contact with the display content. The position t rotates in the moving direction. Specifically, after one point on the display screen 21 is set as the reference point P0 (see FIG. 6A), the display control unit 35 determines that the touch position t on the display screen 21 by the user is the reference point P0. When it is detected that it has moved along the circumferential direction centered on the position, that is, that it has been swiped along the circumferential direction centered on the position of the reference point P0 (see FIG. 6B), the display screen The display content 21 is rotated in the direction in which the contact position t has moved.

  Hereinafter, processing when the display control method, which is a characteristic part of the present embodiment, is described with reference to FIG. FIG. 7 is a flowchart showing the flow of display control processing in the mobile terminal 1.

  As shown in FIG. 7, in the mobile terminal 1, the detection unit 23 detects a touch (contact) on the display screen 21 by the user (S1). Next, the detection unit 23 determines whether or not the user's touch on the display screen 21 detected in step S1 has continued for a predetermined time or more (S2). Here, when it is determined by the detection unit 23 that the touch on the display screen 21 by the user has not continued for a predetermined time (in other words, the touch time by the user was less than the predetermined time) (S2: NO). Ends a series of display control processing. On the other hand, when it is determined by the detection unit 23 that the user has touched the display screen 21 for a predetermined time or longer (S2: YES), the reference point setting unit 31 determines the position touched by the user (contacted position). ) Displays the symbol M (S3).

  Next, the reference point setting unit 31 checks whether or not to accept the position on the display screen 21 touched by the user as the reference point P0 (S4). For this confirmation, for example, a message box indicating whether or not to accept the position touched by the user (that is, the position where the symbol M is displayed) as the reference point P0 is displayed, and the YES button or NO button in the message box is displayed. This can be realized by touching.

  When the position touched by the user is not accepted as the reference point P0 (S4: NO), a series of display control processing ends. When the position touched by the user is accepted as the reference point P0 (S4: YES), the reference point setting unit 31 stores the coordinates (X0, Y0) of the reference point P0 (S5: reference point setting step).

  After the setting of the reference point P0, when the detection unit 23 detects that the user touches the display screen 21 (S6), the operation information acquisition unit 33 acquires the coordinates (Xt, Yt) of the touch position t (S7). Thereafter, the movement of the touch position t is detected based on the coordinates (Xt, Yt) of the touch position t sent continuously or periodically from the detection unit 23 (S8: operation information acquisition step).

  When detecting the movement of the touch position t as the operation information, the display control unit 35 controls the display content of the display screen 21 based on the relative change of the touch position t with respect to the position of the reference point P0 (S9: display). Control step). Specific control in step S9 will be described with reference to FIG.

  The display control unit 35 determines whether or not the distance between the touch position t and the position of the reference point P0 is longer after the movement than before the movement of the touch position t as the operation information (S91). . When the display control unit 35 determines that the distance between the touch position t and the position of the reference point P0 is longer after the movement than before the movement, in other words, the touch position t moves away from the reference point P0. When it is detected (S91: YES), the display screen 21 is controlled to enlarge the display content (S92).

  When the display control unit 35 determines that the distance between the touch position t and the reference point P0 is not longer after the movement than before the movement (S91: NO), It is determined whether or not the distance between the touch position t and the position of the reference point P0 is shorter after the movement than before the movement (S93). When the display control unit 35 determines that the distance between the touch position t and the position of the reference point P0 is shorter after the movement than before the movement, in other words, the touch position t approaches the reference point P0. If it is detected (S91: YES), the display screen 21 is controlled to reduce the display content (S94).

  If the display control unit 35 determines that the distance between the touch position t and the position of the reference point P0 is not shorter after the movement than before the movement (S93: NO), this time, the touch position t and the reference point It is determined whether the distance from the position P0 is constant and the touch position t is moving along the circumferential direction centered on the position of the reference point P0 (S95). When the display control unit 35 determines that the touch position t is moving along the circumferential direction centering on the position of the reference point P0 (S95: YES), the display content is rotated in the direction in which the touch position t is moved. The display screen 21 is controlled to do so (S96).

  When it is determined that the distance between the touch position t and the reference point P0 is constant and the touch position t does not move along the circumferential direction centered on the position of the reference point P0 (S95: NO) If the display content on the display screen is enlarged in step S92, the display content on the display screen is reduced in step S94, or if the display content on the display screen is rotated in step S96, the processing in step S9 is performed. finish.

  As described above, according to the mobile terminal 1 and the display control method of the above embodiment, the reference point P0 is received by the reference point setting unit 31, and then the touch operation on the display screen 21 by the user is detected. In this case, the touch operation is acquired as the operation information, and the display screen 21 is controlled based on the reference point P0 and the touch operation as the operation information. Since the user performs a touch operation for the purpose of operating the display screen after setting the reference point P0, the user controls the mobile terminal 1 with one finger. Moreover, in such a portable terminal 1 and a display control method, since the display screen 21 is controlled based on the reference point P0 and a touch operation aimed at the subsequent operation of the display screen 21, two display screens can be displayed simultaneously. The same processing as when touching 21 can be performed, and the same operability as multi-touch can be provided. As a result, operability can be improved even in a situation where a touch operation can be performed with only one finger.

  In the above, it demonstrated in detail based on one Embodiment. However, the present invention is not limited to the above embodiment. The present invention can be modified in various ways as described below without departing from the scope of the invention.

  In the portable terminal 1 of the above embodiment, whether or not the input is the reference point P0 is determined based on the contacted time, but is not limited to this. For example, a predetermined button is touched After that, the specification may be such that an input as the reference point P0 is accepted.

  The display control method implemented by the reference point setting unit 31, the operation information acquisition unit 33, and the display control unit 35 included in the control unit 30 can also be realized as a program executed by a computer. That is, one contacted position is given to a portable terminal (information terminal) 1 including a touch screen display 20 having a display screen 21 for displaying information and a detection unit 23 for detecting a contacted position on the display screen 21. A reference point setting function for setting as a reference point, an operation information acquisition function for acquiring movement of a contacted position detected by the detection unit as operation information after the reference point is set, and operation information for the position of the reference point As a display control program that realizes a display control function for controlling the display screen 21 based on the relative change in the contacted position acquired as described above.

  In the above-described embodiment, the present invention has been described using an example in which the present invention is applied to the mobile terminal 1. However, the present invention is not limited to this, and is applied to a stationary terminal, a tablet terminal, a PDA (Personal Digital Assistant), and the like. It is also possible.

(Setting of reference point)
In the embodiment described above, the reference point setting unit 31 accepts one contacted position detected by the detection unit 23 as the reference point P0 and stores the position of the reference point P0. In addition, when the reference point setting unit 31 detects that a point on the display screen 21 is touched for a predetermined time or longer, an example in which the touch operation is determined to be an input of the reference point P0 is set as a reference point. Although given as an example, the mode of setting the reference point is not limited to such an example.

  For example, the reference point setting unit 31 uses the end point position as a reference when the trajectory of the contacted position starting from the end of the display screen 21 and ending at a certain position on the display screen 21 is acquired by the detection unit 23. It may be set as a point. FIG. 9 is a diagram showing an example of setting the reference point. As shown in FIG. 9, when a touch operation is performed to slide a finger from outside the display screen 21 to a certain position on the display screen 21 as indicated by an arrow R, the detection unit 23 displays the touch operation display screen 21. The trajectory of the contacted position on the top is acquired. The reference point setting unit 31 sets the end point position of the trajectory of the contacted position acquired by the detection unit 23 as the reference point P0, and displays the symbol M at the position of the reference point P0. Thereby, the reference point P0 can be set by an easy-to-understand and easy operation.

  In addition, the reference point setting unit 31 acquires the locus of the contacted position starting from the end of the display screen 21 and ending at a certain position on the display screen 21 by the detection unit 23, and further, at the end point of the locus When a touch (long press) on the display screen 21 for a time or longer is detected, the end point position may be set as a reference point. Thereby, the reference point P0 can be set by a more explicit operation.

  In addition, the reference point setting unit 31 determines the position at which the tap operation is performed at one point on the display screen 21 and its neighboring position, for example, when the detection unit 23 detects three consecutive tap operations. It may be set as P0. Thereby, the reference point P0 can be set by an easy-to-understand and easy operation. In this case, the number of tap operations is not limited to three.

  In addition, the reference point setting unit 31 performs a predetermined operation when the detection unit 23 detects a predetermined operation including a combination of a tap operation and a long press operation at one point on the display screen 21 and in the vicinity thereof. The position may be set as the reference point P0. Thereby, the reference point P0 can be set by an easy-to-understand and easy operation, and a new operational feeling can be provided to the user.

(Correction of reference point)
Next, correction of the position of the reference point P0 will be described. The reference point setting unit 31 can change the position of the set reference point P0 when a predetermined operation on the mobile terminal 1 is received after the reference point P0 is set. FIG. 10 is a diagram illustrating an example of changing the position of the reference point P0.

  The reference point setting unit 31 recognizes the selection operation for the reference point P0 when the detection unit 23 detects a contact in the vicinity of the set reference point P0. When the reference point setting unit 31 detects the locus of the contacted position following the selection operation, the reference point setting unit 31 changes the position of the reference point to the end point position of the locus. Specifically, as illustrated in FIG. 10A, when the reference point setting unit 31 receives a tap operation on the symbol M indicating the reference point P0 and a drag operation on the symbol M, the reference point setting unit 31 sets the drag operation end point P1. Change the position of the reference point. Thereby, the position of the reference point can be corrected by an intuitive operation such as a drag operation of the reference point.

  As shown in FIG. 10B, when the reference point setting unit 31 receives a tap operation on the symbol M indicating the reference point P0, the reference point setting unit 31 displays an arrow D for receiving an operation for correcting the position of the reference point P0. It may be displayed on the display screen 21. In this case, when a touch operation on the arrow D is detected by the detection unit 23, the reference point setting unit 31 changes the position of the reference point P0 according to the direction of the touched arrow D. Thereby, the position of the reference point P0 can be easily corrected.

  Further, as shown in FIG. 10C, when the reference point setting unit 31 has received a tap operation on the symbol M indicating the reference point P0, the reference point setting unit 31 has shifted to a mode for accepting correction of the position of the reference point P0. A message such as “correction of the base point” may be displayed, and a circular figure C indicating the correctable range of the reference point P0 may be displayed. In this case, when receiving a predetermined operation such as a long press on the display screen 21, for example, the reference point setting unit 31 sets the operation position as the reference point P0. Thereby, a user interface with easy operation can be provided to the user.

  The reference point setting unit 31 shifts to a mode in which correction of the position of the reference point P0 is accepted when a tap operation is performed on the symbol M indicating the reference point P0, and the acceleration acquired by the acceleration sensor included in the mobile terminal 1 The position of the reference point P0 may be changed based on the direction and the size of. Accordingly, for example, the position of the reference point P0 can be corrected by an intuitive operation such as tilting the mobile terminal 1.

  In addition, the reference point setting unit 31 shifts to a mode in which correction of the position of the reference point P0 is received when a tap operation is performed on the symbol M indicating the reference point P0, and the user acquired by the image sensor included in the mobile terminal 1 The position of the reference point P0 may be changed according to the movement of the viewpoint position. Thereby, for example, the position of the reference point P0 can be corrected by an intuitive operation of moving the position of the line of sight with respect to the display screen 21.

  In the example of the correction of the position of the reference point P0 described above, the tap operation for the symbol M indicating the reference point P0 is acquired as an opportunity to accept the correction of the position of the reference point P0. It may be triggered by the acquisition of various operations such as shaking and gripping operations.

(User interface for obtaining operation information)
Next, variations of the user interface for acquiring operation information will be described. In the embodiment described above, the movement of the contacted position t detected by the detection unit 23 is acquired as the operation information after the reference point P0 is set. Specifically, the operation information acquisition unit 33 acquires, as operation information, the movement of the touch position t to the display screen 21 by the user after the reference point P0 is set. An example of a user interface for acquiring the operation information will be described with reference to FIG.

  When the reference point P0 is set, the reference point setting unit 31 may set an operation information acquisition area indicating a range of positions where the operation information acquisition unit 33 can acquire the operation information and display the operation information acquisition area on the display screen 21. . Specifically, as illustrated in FIG. 11A, the reference point setting unit 31 displays a range in which the user can input operation information on the display screen 21 as an operation information acquisition area A1. For example, the operation information acquisition area A1 is a circular area centered on the symbol M indicating the reference point P0. In the operation information acquisition area A1, when the movement of the touch position t by the user is detected by the detection unit 23, the operation information acquisition unit 33 acquires the movement of the touch position t as operation information. The display control unit 35 controls enlargement, reduction, rotation, and the like of the display content of the display screen 21 according to the acquired operation information. Thereby, an area in which operation information can be input is clearly indicated to the user, and various operations on the display screen 21 are facilitated.

FIG. 11B is a diagram illustrating an example of a user interface in operation information acquisition and display content control. In the example shown in FIG. 11B, the reference point setting unit 31 displays the operation information acquisition area A1 on the display screen 21. Then, when the touch position is moved from the position t ₁ to the position t ₂ by the user in order to enlarge the display content, the display control unit 35 forms a shape that simulates the movement of the rubber in the operation information acquisition area A 1. To the operation information acquisition area A2. And the display control part 35 expands the display content of the display screen 21 according to the change of the touch position t. Accordingly, various operations on the display screen 21 are facilitated, and a new operational feeling is provided to the user.

In the state shown in FIG. 11 (b), when the touch position t ₂ by releasing the finger from the user display screen 21 is a non-detection state, the display control unit 35, the operation information acquisition area A2 which displays The original operation information acquisition area A1 is changed. Thereby, a user interface having a new movement imitating rubber is realized. At this time, the display control unit 35 may return the enlarged display content to the original size and display it on the display screen 21. This is useful when it is desired to temporarily enlarge the display contents. On the other hand, when the operation information acquisition area is changed to the original shape, the display control unit 35 may display the enlarged display content on the display screen 21 while being enlarged. In this case, for example, it is useful when it is desired to perform an operation for enlarging the display contents a plurality of times. In FIG. 11B, an example in which the display content is enlarged has been described. However, even when the display content is reduced, the operation information acquisition area A1 is reduced and displayed like a rubber. It is good also as controlling to.

(Release operation information can be acquired)
Next, cancellation of the operation information acquisition possible state will be described. In the embodiment described above, for example, when a touch (long press) for a predetermined time or longer with respect to one point on the display screen 21 is detected, the reference point P0 is set, and the operation information is acquired. The The cancellation of the state where the operation information can be acquired will be described below.

  For example, the operation information acquisition unit 33 may cancel the operation information acquisition enable state when a tap operation is performed on the reference point P0 and its neighboring position (a position indicated by the symbol M). Further, when the operation information acquisition unit 33 receives a tap operation on an area other than the operation information acquisition area A, the operation information acquisition unit 33 may cancel the operation information acquisition enable state.

  Further, the operation information acquisition unit 33 moves the touched position at an arbitrary position on the display screen 21 at a predetermined speed or more by performing an operation in which the user pays on the display screen 21 with a finger or a palm. If accepted, the operation information acquisition possible state may be canceled. Moreover, the operation information acquisition part 33 is good also as cancel | releaseing the acquisition state of operation information, when operation etc. which shake the portable terminal 1 are acquired by various sensors.

  As described above, it is possible to easily shift to the normal control state by canceling the operation information obtainable state.
