[First Embodiment]
Next, the best mode for carrying out the invention will be described in detail with reference to the drawings.

  Referring to FIG. 1, the first embodiment of the present invention includes an input receiving unit 100, a display unit 101, a control unit 102, a specific operation detecting unit 103, a contact coordinate measuring unit 104, and a contact area measuring unit. 105, a pointer coordinate calculation unit 106, a pointer coordinate storage unit 107, and an instruction execution unit 108.

  The input receiving unit 100 is a touch panel device that is used when a user performs input to a terminal, and is a device that detects contact of a user's finger with, for example, an electrode resistance film or infrared rays. In addition, the system which detects the contact of a user's finger | toe in the input reception part 100 can employ | adopt arbitrary systems, and is not limited to these illustrated systems.

  The display unit 101 is a display device that displays information to the user. In general, the input receiving unit 100 is installed on the surface of the display unit 101, and input corresponding to the displayed contents is performed by operating the input receiving unit 100 and the coordinates of the display unit 101 in association with each other.

  The control unit 102 is a part that controls switching of operations such as pointer display, object selection, and command execution in accordance with an operation in which the user touches a finger.

  The specific operation detection unit 103 has a function of counting time, detects a specific operation of the user such as a double click or a long press, and the control unit 102 plays a supplementary role.

  The contact coordinate measurement unit 104 is a part that measures the coordinates of the contact portion of the user's finger.

  The contact area measurement unit 105 is a part that measures the area of the contact part of the user's finger.

  The pointer coordinate calculation unit 106 uses the coordinates of the finger contact portion measured by the contact coordinate measurement unit 104 and the finger contact portion area measured by the contact area measurement unit 105 to determine the direction and distance from the finger contact portion. This is a part for determining an appropriate pointer coordinate by calculating.

  The pointer coordinate storage unit 107 is a part that temporarily stores the pointer coordinates of the object on the screen selected by the user. The stored pointer coordinates are cleared at an appropriate timing such as when an object is determined.

  The instruction execution unit 108 is a part that executes an instruction to be executed when an object is selected when the user selects an object.

  These parts operate as follows.

  In this regard, the overall operation of this embodiment will be described in detail with reference to the flowchart of FIG.

  First, when the user refers to an object displayed on the screen of the display unit 101 and touches the input receiving unit 100 with a finger, the input receiving unit 100 receives this contact (step S101). By receiving the input receiving unit 100, the control unit 102 recognizes the contact of the finger, and measures the coordinates of the touched portion of the finger using the contact coordinate measuring unit 104 (step S102).

  Next, the control part 102 measures the area of the contact part of a finger using the contact area measurement part 105 (step S103).

  Subsequently, the pointer coordinate calculation unit 105 calculates a direction in which the pointer is displayed around the finger contact portion based on the coordinates of the finger contact portion (step S104). In addition, the pointer coordinate calculation unit 105 calculates the distance from the finger contact portion to the pointer based on the area of the finger contact portion (step S105).

  Thereafter, the pointer coordinate calculation unit 105 determines appropriate pointer coordinates from which the user can easily select an object from the display direction and distance of the pointer centered on the finger contact portion calculated in steps S104 and S105 (step S106). ).

  Then, the control unit 102 stores the appropriate pointer coordinates determined in step S106 in the pointer coordinate storage unit 107 (step S107).

  In addition, the control unit 102 instructs the display unit 101 to display a pointer at the appropriate pointer coordinate position determined in step S106, and the display unit 101 displays a pointer according to the instruction (step S108). . At this time, the position of the pointer may be further away from the finger as the area of the contact portion of the finger is larger, and the position of the pointer may be closer from the finger as the area is smaller. Further, either the display direction or the distance of the pointer from the finger contact portion may be a fixed value.

  Next, when the user moves the finger on the screen (Yes in step S109), the input receiving unit 100 detects the movement of the finger and transmits it to the control unit 102, and calculates an appropriate pointer coordinate from the coordinate of the finger contact portion. The operation of recalculating and displaying the pointer (steps S102 to S108) is repeated (step S109).

  On the other hand, when there is no movement of the user's finger (No in step S109), and the specific operation performed to confirm the object such as double-click or long press is detected by the specific operation detection unit 103. (Yes in step S110) Proceed to step S111. On the other hand, when neither the movement of the user's finger nor the confirmation operation is detected (No in step S110), the process waits until either of them is detected.

  In addition, although the movement of the user's finger is excluded from the target of the confirmation operation detected by the specific operation detection unit 103 this time, it is not always necessary to set in this way. A predetermined finger movement (gesture) may be a target of a confirmation operation detected by the specific operation detection unit 103. Specific examples of gestures include moving the finger on the screen in a certain time after the user lifts the finger from the screen, moving the finger from the right to the left at a certain speed, etc. . In this case, the determination criterion in step S109 is “Have the user moved his / her finger on the screen? (Excluding predetermined gesture)”.

  Next, the final pointer coordinate stored in the pointer coordinate storage unit 107 is confirmed as the click position (step S111), and the command execution unit 108 executes the command at the time of object designation (step S112).

  Next, the effect of this embodiment will be described.

  In the present embodiment, the pointer coordinate calculation unit 106 determines an appropriate pointer coordinate from the coordinates of the finger contact portion calculated by the contact coordinate measurement unit 104 and the area calculated by the contact area measurement unit 105. A pointer is displayed on the display unit 101, and the user visually checks the pointer to determine an object. As a result, it is possible to prevent erroneous input in object specification on a touch panel display with a small input screen, and to change the distance from the contact coordinates of the finger to the pointer flexibly and intuitively, thereby enabling more detailed object specification. .

[Second Embodiment]
Referring to FIG. 3, the second embodiment of the present invention is different from the first embodiment in that an operation history recording unit 109 is provided. Further, the operation history recording unit 109 stores the display direction of the pointer when the user determines the object, the distance to the pointer, and the contact area of the finger. When the pointer coordinate calculation unit 106 calculates the pointer coordinates, the pointer display direction, the distance to the pointer, and the contact area of the finger when the user's object is recorded, which is recorded by the operation history recording unit 109, are calculated. Used as the default value of.

  The overall operation of this embodiment will be described in detail with reference to the flowchart of FIG.

  First, when the user refers to an object displayed on the screen of the display unit 101 and touches the input receiving unit 100 with a finger, the input receiving unit 100 receives this contact (step S201).

  Accordingly, the control unit 102 recognizes the finger contact, and measures the coordinates of the finger contact portion using the contact coordinate measurement unit 104 (step S202). Next, the control part 102 measures the area of the contact part of a finger using the contact area measurement part 105 (step S203).

  Subsequently, the pointer coordinate calculation unit 105 calculates a direction in which the pointer is displayed around the finger contact portion based on the coordinates of the finger contact portion (step S204). Further, the distance from the finger contact portion to the pointer is calculated based on the area of the finger contact portion (step S205).

  Next, the pointer coordinate calculation unit 105 acquires the pointer display direction, the distance to the pointer, and the contact area of the finger when the user determines the object from the operation history recording unit 109, and calculates the average value of each. This is calculated and set as default values of distance, direction, and area (step S206).

  From the pointer display direction centered on the contact portion of the finger, the distance, and the default values of the calculated distance, direction, and area, appropriate pointer coordinates that allow the user to select an object are determined (step S207). .

  Then, the control unit 102 stores the appropriate pointer coordinates determined in step S207 in the pointer coordinate storage unit 107 (step S208). In addition, the control unit 102 instructs the display unit 101 to display a pointer at the position of the pointer coordinates, and the display unit 101 displays the pointer according to this instruction (step S209).

  Next, when the user moves the finger on the screen (Yes in step S210), the input receiving unit 100 detects the movement of the finger and transmits it to the control unit 102, and calculates an appropriate pointer coordinate from the coordinates of the finger contact portion. The operation of recalculating and displaying the pointer (steps S202 to S209) is repeated (step S210).

  On the other hand, when there is no movement of the user's finger (No in step S210), and when the specific operation detection unit 103 detects an object confirming operation such as a double click or a long press (Yes in step S211), step Proceed to S210.

  On the other hand, when neither the movement of the user's finger nor the confirmation operation is detected (No in step S211), the process waits until either of them is detected.

  Next, the final pointer coordinate stored in the pointer coordinate storage unit 107 is confirmed as the click position (step S212), and the operation history recording unit 109 determines the display direction of the pointer when the user determines the object. The distance to the pointer and the contact area of the finger are recorded (step S213). Finally, the instruction execution unit 108 executes an instruction at the time of object designation (step S214).

  Next, the effect of this embodiment will be described.

  In the present embodiment, in addition to the effects of the first embodiment, the operation history recording unit 109 stores the display direction of the pointer when the user determines the object, the distance to the pointer, and the contact area of the finger. By calculating the appropriate pointer position using the pointer display direction / distance and the average value of the finger area as default values, the object is determined in consideration of the user's daily habit and finger thickness. There is an effect that it is possible to determine easy-to-use pointer coordinates.

  In addition, when there are a plurality of users, each user used by the operation history recording unit 109 may be classified and stored. By doing so, it is more reliable to obtain the above-mentioned effect of “considering the user's daily wrinkles and finger thickness”.

  Next, the operation of the best mode for carrying out the present invention will be described using specific examples.

  Hereinafter, the best embodiment will be specifically described with reference to FIG. 5 to FIG. 8 as an example applied to a case of selecting a store on a map in a mobile phone equipped with a touch panel.

  There are various types of touch panels, but in the embodiments of the present invention, a matrix type resistive film method will be described.

  In the specific operation detection unit 103, it is assumed that a double-click operation for releasing the finger from the touch panel screen and clicking again within S seconds is set in advance as an object determination operation.

  As described above, the touch panel method and the object determination operation are merely examples.

  Refer to the flowchart of FIG. 5 for description of operation | movement.

  First, when the user refers to a store on the map displayed on the screen of the display unit 101 and touches the input reception unit 100 with a finger (step S301), the control unit 102 recognizes the finger contact. When the finger contact is recognized, the contact coordinate measuring unit 104 measures the coordinates of the contact portion from the electrode through which the current flows (step S302), and the contact area measuring unit 104 measures the area of the contact portion from the contact portion current value. (Step S303).

  Specifically, the coordinates of the contact portion are obtained by converting a plurality of electrodes through which current has passed in a matrix-type resistive touch panel into position information, of which the position information of the electrode closest to the center is used. . Further, the area of the contact portion can be measured by measuring the amount of current value of the matrix type resistive film type touch panel.

  Next, the pointer coordinate calculation unit 106 determines the display direction of the pointer around the contact portion using the measured coordinates of the contact portion (step S304). Any method for determining the display direction of the pointer around the contact portion can be adopted. For example, the display direction of the pointer may be a vertical direction from the measured coordinates of the contact portion (see FIG. 6). Further, for example, an isosceles triangle of a triangle connecting the measured coordinates of the contact portion and the upper two of the four corners of the touch panel display unit may be set as the pointer display direction (see FIG. 7).

Next, the pointer coordinate calculation unit 106 calculates the distance X (mm) to the pointer with the contact portion as the center using the measured area of the contact portion (step S305). The distance from the contact portion to the pointer, using a contact area S in which the measured, the default value of the pointer distance Xδ (mm), and the default value S _[delta] of the contact area, and an optional proportionality coefficient a Alternatively, the following equation 1 may be obtained.

但し、
Ｘ：接触部分からポインタまでの距離
Ｓ：測定した接触部分の面積
Ｘ_δ：ポインタ距離のデフォルト値
Ｓ_δ：接触面積のデフォルト値
ａ：比例係数
であるものとする。

However,
X: Distance from the contact portion to the pointer S: Area of the measured contact portion X _δ : Default value of the pointer distance S _δ : Default value of the contact area a: Proportional coefficient

  When calculated in this way, the position of the pointer is calculated such that the position of the pointer is further away from the finger as the area of the contact portion of the finger is larger, and the position of the pointer is closer to the finger as the area is smaller. This is shown in FIG. Further, the operation history recording unit 109 shown in the second embodiment is provided, and the default value Xδ of the pointer distance and the default value Sδ of the contact area of Equation 1 are determined using the operation history of the user, By calculating the pointer position, it is possible to achieve the above-described effect that it is possible to determine the pointer coordinates at which an object can be easily determined in consideration of the user's daily wrinkles and finger thickness. This is an effect that cannot be obtained by the prior art.

  Next, appropriate pointer coordinates that allow the user to select an object are determined from the display direction and distance of the pointer with the finger contact portion as the center (step S306). The determined pointer coordinates are stored in the pointer coordinate storage unit 107 (step S307), and the pointer is displayed through the display unit 102 (step S308).

  At this time, the pointer coordinate storage unit 107 stores the calculated pointer coordinates and date and time.

  Next, when the user moves his / her finger on the screen, the specific operation detection unit 103 detects the movement of the finger and transmits it to the control unit 102, recalculates the appropriate pointer coordinates from the coordinates of the contact portion of the finger, and moves the pointer. The display operation (steps S302 to S308) is repeated (step S309).

  Next, when the specific operation detection unit 103 detects an operation of releasing the finger from the panel (Yes in step S310), the counting is started (step S311).

  Furthermore, when the specific operation detection unit 103 is clicked again within S seconds after releasing the finger from the panel, this is detected as a double-click confirmation operation (Yes in step S312) and stored in the pointer coordinate storage unit 107. The store of the final pointer coordinates that has been made is determined (step S313). At the same time, the final pointer coordinates of the operation history 109 are recorded (step S314). An example of the recorded contents is shown in FIG.

  Finally, the command execution unit 108 displays store information as a command at the time of designating the store (step S315).

  In this way, by applying the present invention to the present embodiment, an error may occur in the detailed object designation such as selecting a store on the map in the input operation of the touch panel of a small mobile terminal such as a mobile phone having a touch panel. In addition to preventing input, the distance from the contact coordinates of the finger to the pointer can be changed flexibly and intuitively, so that detailed object designation is possible.

  The first effect of the present invention is to prevent erroneous input and enable fine object specification in a touch panel display with a small input range mounted on a small portable terminal or the like.

  The reason is that by calculating the coordinates of the appropriate pointer from the coordinates and area of the finger and displaying them on the screen, the user can visually confirm that the pointer has selected the object and perform the determination operation. Because.

  The second effect of the present invention is that it can be used as an input means for displaying various objects such as a software keyboard, a map, and a web browser because the consistency of the screen configuration can be maintained.

  The reason is that the pointer is displayed on the original screen and the object is designated, so that it is not necessary to change the screen configuration at all.

  The third effect of the present invention is that the user can intuitively move a pointer that designates an object to an appropriate position.

  The reason is that the position of the pointer is changed not only by the coordinates of the contact part of the finger but also by the area of the contact part, and when the finger is placed on the screen, the pointer is brought closer to the finger and the finger is laid on the screen. This is because the operation of moving the pointer away from the finger is possible.

  The fourth effect of the present invention is that it is possible to determine the pointer coordinates that make it easy to determine an object in consideration of the user's daily wrinkles and finger thickness.

  The reason for this is that the user's operation history is used to determine default values for the pointer direction, pointer distance, and finger contact area, and by calculating the appropriate pointer position, This is because the pointer coordinates can be determined in consideration of the thickness.

  Each embodiment of the present invention can be realized by hardware, software, or a combination thereof.

  Moreover, although the above-described embodiment is a preferred embodiment of the present invention, the scope of the present invention is not limited only to the above-described embodiment, and various modifications are made without departing from the gist of the present invention. Implementation in the form is possible.

  The present invention can be used for various devices having a touch panel display, but is particularly suitable for a small portable terminal when the display portion is small.
