Next, embodiments of the present invention will be described based on examples.
A. First embodiment:
(A1) Configuration of mobile terminal:
FIG. 1 is a configuration diagram illustrating a configuration of a mobile terminal 10 as an embodiment of the present invention. The mobile terminal 10 is a mobile phone in which a display unit that displays an image and a touch panel are superimposed. In this embodiment, a configuration is adopted in which the touch panel is placed on the color LED panel. The touch panel is a capacitive type. Further, not only the capacitance method but also a resistance film method or an electromagnetic induction method may be adopted. The mobile terminal 10 is connected to the base station BS by radio, and transmits and receives an audio signal as a mobile phone via the base station BS. Furthermore, the mobile terminal 10 is connected to the Internet INT via the base station BS.

  As shown in FIG. 1, the mobile terminal 10 is configured around a main control unit 110, and includes a touch panel 120, a display unit 122, a communication unit 124, a call control unit 126, a key input unit 128, a voice output unit 130, A GPS receiver 132 is connected to the main control unit 110. The main control unit 110 includes a CPU 112, a RAM 114, and a ROM 116, and controls the overall operation of the mobile terminal 10. The ROM 116 stores a program (contact operation control program) for performing a contact operation control process, which will be described later, and the CPU 112 reads the data into the RAM 114 and executes it to perform the contact operation control process. The touch panel 120 receives a touch operation by a user using a finger or a dedicated pen (hereinafter, the finger or the dedicated pen is simply expressed as “finger”). The contact operation is a variety of operations performed by the user touching the touch panel with a finger. The contact operation includes a plurality of types of contact with a finger on the touch panel, such as tap, flick, pinch in / out, and drag, which are operations having different meanings.

  The display unit 122 displays various images for the user. Since the touch panel 120 and the display unit 122 are provided so as to overlap each other and the displayed image is processed so that the display image operates in accordance with the movement of the user's finger by a touch operation on the touch panel by the user, it is apparently The user can directly operate the display image with a finger. The communication unit 124 is a circuit for performing data communication or voice communication with the base station BS. The communication unit 124 can access the Internet INT via the base station BS. The call control unit 126 is a circuit that performs incoming calls and calls for voice calls, conversion of voice signals and electrical signals, and the like. The mobile terminal 10 operates as a mobile phone by including the call control unit 126 and the communication unit 124. The key input unit 128 is an operation button for the user to perform an operation other than the operation using the touch panel 120. For example, it is used for the user to display a main menu screen on the display unit 122.

  The voice output unit 130 outputs voice to the user when executing various applications (for example, route guidance by voice, guidance on operation method of the mobile terminal 10) provided in the mobile terminal 10. The GPS receiver 132 receives the radio waves transmitted from the artificial satellites constituting the GPS (Global Positioning System) to acquire the coordinates (longitude / latitude) of the current position of the mobile terminal 10. This device is used when information on the current position is necessary for executing various applications (for example, an application for performing route guidance) provided in the mobile terminal 10.

(A2) Contact operation control process:
Next, the contact operation control process performed by the mobile terminal 10 will be described. The contact operation control process recognizes each contact operation (tap, drag, flick, etc.) performed by the user on the display image when an image is displayed on the mobile terminal 10, and performs a process corresponding to the contact operation. It is a process to be executed. In describing the contact operation control process, the main contact operation will be described first. FIG. 2 is an explanatory diagram illustrating main contact operations used for the operation of the mobile terminal 10. As main contact operations, tap, drag, flick, pinch in, and pinch out will be described. As illustrated in FIG. 2, the tap is a touch operation in which a certain position on the touch panel 120 is touched with a fingertip lightly. A tap may be distinguished as a different contact operation depending on the length of a period in which the touch panel 120 is in contact (hereinafter also referred to as a contact period). Next, the drag is a contact operation in which the touch panel 120 is moved up, down, left, and right with a finger in contact. A flick is a contact operation such as flicking the touch panel 120 with a finger. Generally, the flick is used when scrolling the display image displayed on the display unit 122. Next, pinch-out is a contact operation that presses the touch panel 120 with two fingers and widens the distance between the fingers. Generally, pinch out is used when displaying a display image in an enlarged manner. Pinch-in is a contact operation that presses the touch panel 120 with two fingers and narrows the distance between the fingers. Generally, pinch-in is used when a display image is reduced and displayed.

  Based on the content of the contact operation described above, the contact operation control process performed by the mobile terminal 10 will be described. In the present embodiment, a contact operation control process performed by the mobile terminal 10 when a map image is displayed as a display image on the display unit 122 will be described. The map image displayed on the display unit 122 is acquired by the mobile terminal 10 via the Internet INT. FIG. 3 is a flowchart illustrating the flow of the contact operation control process performed by the mobile terminal 10 when a map image is displayed on the display unit 122. The contact operation control process is started at the same time when the mobile terminal 10 acquires a map image via the Internet INT and displays it on the display unit 122. When the contact operation control process is started, the mobile terminal 10 enters a standby state until the user performs a contact operation on the touch panel 120 (step S102: NO). When the user performs a touch operation on the touch panel (step S102: YES), the mobile terminal 10 (main control unit 110) recognizes the touch operation.

  When the mobile terminal 10 recognizes that the contact operation is a drag, the mobile terminal 10 sets a prepared flag to 0 (F = 0) (step S104). Then, the map image is moved in accordance with the direction of the finger that the user moves as a drag (step S106). The moving amount of the map image is set so as not to be substantially equal to the moving amount of the finger. Thereafter, until the finger touching the touch panel of the user as a drag is released, in other words, until the finger is released from the touch panel 120, the mobile terminal 10 matches the movement of the user's finger (up, down, left, and right). The display image (map image) is moved (step S108: NO). When the contact of the finger as a drag is released (step S108: YES), the mobile terminal 10 resets the flag to 0 (F = 0) (step S140).

  On the other hand, when the portable terminal 10 recognizes that the contact operation by the user is a pinch-in / out in step S102, the portable terminal 10 sets a flag to 0 (F = 0) (step S110). Then, the display image (map image) is enlarged or reduced according to the change in the width of the two fingers holding the touch panel 120 by the user (step S112). Thereafter, the portable terminal 10 enlarges or reduces the map image according to the width of the user's two fingers until the finger contact with the user's touch panel as the pinch-in / out is released (step S113: NO). ). When the finger contact as the pinch-in / out is released (step S113: YES), the mobile terminal 10 resets the flag to 0 (F = 0) (step S140).

  If the contact operation by the user is a flick in step S102, the mobile terminal 10 sets a flag to 1 (F = 1) (step S114). Then, the mobile terminal 10 scrolls the map image in the direction in which the user flicks the finger (step S116). Then, it is monitored whether the user taps while scrolling the map image (step S118). If the user does not tap during the scrolling of the map image (step S118: NO), the map image continues to be scrolled until a predetermined period (for example, 1 second) elapses (step S120: NO), When the predetermined period has elapsed, the scrolling of the map image is stopped (step S122), and the flag is reset to 0 (F = 0) (step S140). On the other hand, when the user taps while scrolling the map image by flicking (step S118: YES), the mobile terminal 10 advances the process to step S126. The process of step S126 will be described later.

  Next, when the mobile terminal 10 recognizes that the contact operation by the user is a tap in step S102, the mobile terminal 10 sets a flag to 0 (F = 0) (step S124). Thereafter, the mobile terminal 10 checks whether the flag is F = 0 or F = 1 (step S126). That is, it is determined whether the tap performed by the user is an operation performed while the map image is scrolled (F = 1) or an operation performed when the map image is not scrolled (F = 0). When the flag is 0 (step S126: F = 0), that is, when the tap is an operation performed when the map image is not scrolled, the mobile terminal 10 receives the user's tap as a tap. It is monitored whether the finger touch on the touch panel 120 is released within a predetermined period (period T1) (step S128). That is, it is monitored whether or not the contact period by the tap is within T1. If the user's touch on the touch panel 120 as a tap is not released even after the period T1 has elapsed (step S128: YES), the mobile terminal 10 causes the user to touch the finger as a tap. A mark (hereinafter also referred to as a check mark) is displayed at the position of the map image, and the absolute position (longitude / latitude) on the map of the position where the mark is displayed is stored in the RAM 114 (step S130). The display of the check mark means that the user keeps the position of the map image as a record. The display mode of the check mark will be described later. On the other hand, if the user's finger touch on the touch panel 120 is released within the period T1 (step S128: NO), the mobile terminal 10 advances the process to step S140 and sets the flag to 0 (F = Reset to 0).

  Next, processing in the case where the flag is 1 when the mobile terminal 10 confirms the flag in step S126 (step S126: F = 1) will be described. If the flag is 1, that is, if the tap is an operation performed during scrolling (step S118: YES), the mobile terminal 10 stops scrolling the map image (step S132). Thereafter, the mobile terminal 10 monitors whether the user's finger touch on the touch panel 120 as a tap is released within a predetermined period (period T2) (step S134: NO → step S136). The period T2 is longer than the above-described period T1 (T2> T1). If the touch of the user's finger on the touch panel 120 as a tap is released before the period T2 has elapsed (step S136: NO → step S134: YES), the mobile terminal 10 sets the flag to 0 (F = 0) (step S140).

  On the other hand, when the contact of the finger on the touch panel 120 of the user as a tap is not released even after the period T2 has elapsed (step S136: YES), the mobile terminal 10 is a map in which the user touches the finger as a tap. A mark (check mark) is displayed at the position of the image, and the coordinates of the position at which the mark is displayed are stored in the RAM 114 (step S130).

  The mobile terminal 10 repeatedly performs the above-described processing (steps S <b> 102 to S <b> 140) according to each contact operation by the user until the display of the map image on the display unit 122 is ended (step S <b> 142: NO), and the user presses the key. When the display of the map image is ended by a predetermined operation on the input unit 128 or the touch panel 120, the contact operation control process is ended together with the display end (step S142).

  Next, a process in which the mobile terminal 10 displays a check mark on the map image in step S130 will be described. FIG. 4 is an explanatory diagram showing a state in which the mobile terminal 10 displays a check mark on the map image. As illustrated in FIG. 4, the mobile terminal 10 displays a check mark at the position of the map image that is touched by the user's finger as a tap. Further, when the user performs a plurality of taps that satisfy the condition for displaying the check mark, the mobile terminal 10 may display a plurality of check marks on the map image at the same time. It is also possible to set a limit on the number, display the checkmarks preferentially from the new ones, and delete the old checkmarks.

  The contact operation control process has been described above. Hereinafter, the effect of the first embodiment will be described with reference to FIG. As described above, the portable terminal 10 does not perform the process for the contact operation during the period T <b> 2 until the contact from the touch panel 120 is released with respect to the tap performed by the user while scrolling. In other words, when the user's finger is continuously in contact with the touch panel even after scrolling is stopped by a tap accompanied by stoppage of scrolling, other contact such as dragging or flicking is maintained within the period T2 while the contact is continued. Even if the operation is performed, the processing by the contact operation is not performed. That is, it is recognized as “scroll stop”.

  In addition, since a tap during scrolling has two meanings, “only stop scrolling” and “display a check mark in addition to stopping scrolling”, a tap caused by a finger contact within the period T2 is “only stop scrolling”. In addition, taps caused by finger contact for the period T2 or more are distinguished so as to mean “displaying a check mark in addition to stopping scrolling”. Furthermore, when the user wants to stop scrolling and display a check mark by scrolling the tap, the period of finger contact with the tap accompanied by the display of the check mark in the normal state (when not scrolling) By continuing contact for a longer period (period T2 or longer) (period T1), scrolling is stopped and a check mark is displayed. By doing in this way, the misrecognition contrary to a user's will can be suppressed with respect to the contact operation called a tap by a user, and an appropriate process can be performed with respect to the contact operation by a user.

B. Second embodiment:
Next, the second embodiment will be described. In the second embodiment, a contact operation control process performed by the mobile terminal 10 on a display screen including a hyperlink will be described. As an example, a case will be described in which an image (search result image) indicating a search result based on a search process performed by a search engine is displayed on the display unit 122 as a display image. FIG. 6 is an explanatory diagram showing the mobile terminal 10 in which a search result image is displayed as a display image on the display unit 122. The search result image includes hypertext (hyperlink) as a search result item. The search result and the search result image are obtained from a search server connected to the mobile terminal 10 via the Internet INT.

  FIG. 7 is a flowchart illustrating the flow of the contact operation control process performed by the mobile terminal 10 when the search result image is displayed on the display unit 122. The contact operation control process in the second embodiment is started at the same time when the mobile terminal 10 acquires a search result image via the Internet INT and displays it on the display unit 122. The different processing between the contact operation control process in the second embodiment and the contact operation control process in the first embodiment is the process surrounded by a broken line in FIG. 7, that is, step S128A, step S130A, step S136A, and step S136A: YES. This is a step ((B) in the figure) for proceeding with the process. Other processes are different only in the display image (second embodiment: search result image, first embodiment: map image), and the processing contents are the same as those in the first embodiment. Is attached. Therefore, the description of the contact operation control process in the second embodiment is based on the case where the mobile terminal 10 recognizes that the contact operation by the user is a tap in step S102 of FIG. 7 (step S102 → steps S124 to S140). A description of the processing in steps S102 to 122 is omitted.

  In step S102 of FIG. 7, when the mobile terminal 10 recognizes that the contact operation by the user is a tap, the mobile terminal 10 sets a flag to 0 (F = 0) (step S124). Thereafter, the mobile terminal 10 checks whether the flag is F = 0 or F = 1 (step S126). That is, it is determined whether the tap performed by the user is an operation performed while the search result image is scrolled (F = 1) or an operation performed when the search result image is not scrolled (F = 0). When the flag is 0 (step S126: F = 0), that is, when the tap is an operation performed when the search result image is not scrolled, the mobile terminal 10 causes the user to tap. It is determined whether the position on the touch panel 120 is on the hypertext (step S128A). When the position where the user taps is on the hypertext (step S128A: YES), the jump is made to the link destination of the tapped hypertext (step S130A). On the other hand, when the position where the user taps is a position other than the hypertext (step S128A: NO), the mobile terminal 10 advances the process to step S140 and sets the flag to 0 (F = 0). Reset to.

  Next, processing in the case where the flag is 1 when the mobile terminal 10 confirms the flag in step S126 (step S126: F = 1) will be described. If the flag is 1, that is, if the tap is an operation performed while scrolling (step S118: YES), the mobile terminal 10 stops scrolling the search result image (step S132). Thereafter, the mobile terminal 10 monitors whether the user's finger touch on the touch panel 120 as a tap is released within a predetermined period (period T3) (step S134: NO → step S136A). The period T3 is set to a period longer than the contact period with the touch panel 120 by a tap generally performed by a normal user (for example, T3 = 3 seconds). If the user's touch on the touch panel 120 as a tap is released before the period T3 has elapsed (step S136A: NO → step S134: YES), the mobile terminal 10 sets the flag to 0 (F = 0) (step S140). On the other hand, when the touch of the finger on the touch panel 120 of the user as a tap is not released even after the period T3 has elapsed (step S136A: YES), the mobile terminal 10 advances the process to step S128A. Since the processing content after step S128A is the same as that of the first embodiment, a description thereof will be omitted.

  The contact operation control process in the second embodiment has been described above. Hereinafter, the effect of the second embodiment will be described with reference to FIG. As described above, the mobile terminal 10 does not perform the process for the contact operation during the period T3 until the touch that is performed by the user during the scrolling is released from the touch panel 120. That is, when the touch is continuously touched by the tap accompanied by the stop of the scroll, the touch operation is continued within the period T3, and other contact operations such as dragging and flicking are performed while the contact is continued. However, the process by the contact operation is not performed. That is, as in the first embodiment, it is recognized as “stop of scrolling”.

  Further, the tap to the position of the hyperlink being scrolled has two meanings of “only stop of scrolling” and “jump to the link destination of the hyperlink in addition to the stop of scrolling”. The tap is distinguished to mean only “stop of scrolling”, and the tap caused by contact for the period T3 or more means “jump to link destination in addition to stopping of scroll”. By doing in this way, when the search result image is displayed as a display image, it is possible to suppress misrecognition against the user's will for the touch operation by the user, and Appropriate processing can be performed.

C. Variations:
The present invention is not limited to the above-described examples and embodiments, and can be implemented in various modes without departing from the gist thereof. For example, the following modifications are possible.

(C1) Modification 1:
In the above embodiment, a mobile phone is used as the mobile terminal 10, but the mobile terminal 10 is not limited thereto, and other mobile terminals such as tablet terminals and PDAs are used as long as the mobile terminal has a touch panel superimposed on a display unit for displaying images. can do. Even if such a portable terminal is adopted, the same effect as in the above embodiment can be obtained.

(C2) Modification 2:
In the above embodiment, the tap is adopted as the contact operation for stopping the scrolling. However, the present invention is not limited to this, and other contact operations such as flicking and dragging may be adopted. For example, when dragging is adopted, the processing contents (steps S124 to S140) in the tap shown in FIG. 2 are replaced with dragging, and the processing in step S130 (FIG. 3) is replaced with “move image”. Is possible. Even if it does in this way, the effect similar to the said Example can be acquired.

(C3) Modification 3:
In the above-described embodiment, the map image and the search result image are adopted as the display image. If there are, various images can be adopted. For example, in the contact operation control process (FIG. 3) of the first embodiment, when a photographic image is adopted as the display image, the process of step S130 is adopted instead of “enlarged display of the photograph around the tap position”. It is good. In this case, since the tap being scrolled has two meanings of “only stop scrolling” and “in addition to stopping scrolling, the photograph is enlarged and displayed around the tap position”, the tap by contact within the period T2 is not “Stop scrolling only” can be distinguished from a tap by contact for a period of time T2 or longer, which means “in addition to stopping scrolling, the photograph is enlarged and displayed around the tap position”. As described above, even when various images are used as the display image, erroneous recognition contrary to the user's will is suppressed with respect to the user's tap operation, and appropriate processing is performed for the user's contact operation. be able to.

(C4) Modification 4:
In the above-described embodiment, the display image is scrolled by flicking (FIGS. 3 and 7). However, the display image is not limited to this and depends on external factors such as other operations and external signals. May scroll. For example, the mobile terminal may include an acceleration sensor, and the mobile terminal may scroll the display image when the user shakes the mobile terminal at a predetermined acceleration or higher. In addition, the mobile terminal may include a voice recognition module, and the mobile terminal may scroll the display image when the user emits a predetermined sound (for example, “scroll”) to the mobile terminal. As described above, the operation meaning the start of scrolling is not limited to the touch operation on the touch panel, but various external factors given to the mobile terminal such as various user operations on the mobile terminal and external signals (for example, voice). Can be adopted. Even if it does in this way, the effect similar to the said Example can be acquired.

(C5) Modification 5:
In the first embodiment, the process of step S130 in the contact operation control process (FIG. 3) is “display a check mark”. However, the present invention is not limited to this, for example, an enlarged map display centered on the tapped position. In addition, it is possible to perform specific processing related to the position of the map image, such as displaying geographical detailed information of the tapped position. Even if it does in this way, the effect similar to the said 1st Example can be acquired.

(C6) Modification 6:
In the first and second embodiments described above, if the tap being scrolled continues to be touched by the tap, the contact period is a predetermined period (first embodiment: period T2, second embodiment). : Until the period T3) elapses, the processing by other contact operations is not performed. However, the present invention is not limited to this, and the processing by other contact operations may be selectively performed. For example, even if the contact period of the finger by the tap is before the predetermined period has elapsed, for example, the display image may be moved by dragging following the contact of the finger by the tap. Even in this case, the mobile terminal 10 erroneously recognizes the user's contact operation and performs a process contrary to the user's will (for example, a check mark is displayed even though the contact period of the tap is within the predetermined period). Can be suppressed).

(C7) Modification 7:
In the above-described embodiment, the mobile terminal 10 performs the contact operation control process by a sequential process, but may perform the contact operation control process by an event-driven method. Even if it does in this way, the effect similar to the said Example can be acquired.

(C8) Modification 8:
When the user continues to touch the touch panel 120 with a tap accompanied by a scroll stop, the mobile terminal 10 in the above embodiment has a predetermined contact period (first embodiment: period T2, second embodiment: period T3). After the elapse of time, it is assumed that other processing can be performed even if the user continues to touch the touch panel 120 by a tap accompanied by the stop of scrolling (see FIGS. 5 and 8). Such a mode can be adopted. That is, it is possible to adopt a mode in which the portable terminal 10 does not perform other processes regardless of the contact period until the user's contact with the touch panel that accompanies the stop of the scroll is released. Even in this case, similarly to the above-described embodiment, it is possible to suppress misrecognition against the user's will and perform appropriate processing for the contact operation by the user.

(C9) Modification 9:
In the first embodiment (see FIG. 5), the period T2 is longer than the period T1, but the present invention is not limited to this, and the period T2 and the period T1 may be the same length.
