Description

  The present invention relates to a technique for preventing erroneous operation of a terminal.

  In recent years, portable terminals with excellent portability (hereinafter referred to as portable terminals) have been widely used. Such a portable terminal is called, for example, a smartphone, and is equipped with various new functions as compared with a conventional terminal.

  In addition, for example, there are some operations that are performed mainly by software input while minimizing the operations by hardware keys. Specifically, the user inputs various operations to the terminal by performing specific operations (for example, tap, swipe, pinch, etc.) on the touch panel of the screen.

JP 2012-156665 A

  Here, in a mobile terminal such as a smartphone, an erroneous operation sometimes occurs due to the operability that an operation is input by simply tapping (touching) the screen. For example, when a finger accidentally touches the screen, an unintended operation is executed, or an unintended screen expansion or transition is executed.

  Furthermore, such portable terminals are often used in various situations and places such as while walking or in trains because of their portability. For this reason, when a user hits a person, crawls, or shakes a lot in a train while using a mobile terminal, the user often mistakenly touches the screen. was there. Further, for example, if a finger touches a link on the screen (such as an advertisement link) by mistake, the screen may transition to an unintended link destination.

  Note that, as an example of a technique related to erroneous operation prevention, for example, Patent Document 1 describes a technique for key-locking a mobile phone. However, although the technique described in Patent Document 1 can prevent an erroneous operation when the mobile phone is not used, it cannot prevent the erroneous operation when the mobile phone is used.

  The present invention has been proposed in view of the above points, and an object of the present invention is to provide a technique for invalidating an operation based on an erroneous operation when an erroneous operation occurs during use of the terminal. .

  In order to solve the above-described problems, the present invention is a terminal having touch-type input means, which obtains a contact surface shape from contact surface coordinates based on an input operation to the touch-type input means. The shape acquisition means, the storage means for storing the reference contact surface shape acquired from the contact surface coordinates based on the user's normal input operation, and the contact surface shape and the reference contact surface shape are not the same or dissimilar In this case, an invalidating means for invalidating an input operation to the touch type input means is provided.

  According to the embodiment of the present invention, when an erroneous operation occurs during use of the terminal, an operation based on the erroneous operation can be invalidated.

  Hereinafter, preferred embodiments of the present invention will be described.

[Embodiment 1]
<Configuration>
(Network configuration)
FIG. 1 is a network configuration diagram according to an embodiment of the present invention. A mobile terminal 1 and a server 2 are connected via a network 3.

  The mobile terminal 1 includes information processing devices such as a smartphone, a tablet terminal, a mobile phone, a PC (Personal Computer), and a PDA (Personal Digital Assistants). In this embodiment, a user mainly uses information (for example, a web page or It is a user terminal used for receiving, displaying and browsing advertisements and the like. For this reason, the mobile terminal 1 includes a web browser and various applications, for example.

  The server 2 is a server that provides information displayed on the terminal screen to the user's portable terminal 1. Specifically, it may be a web server that provides a web page to the mobile terminal 2. Further, it may be an advertisement distribution server that provides an advertisement (for example, a banner advertisement, a text advertisement, etc.) to the mobile terminal 2. In the present embodiment, specific delivery methods of advertisements to the mobile terminal 1 include, for example, advertisement delivery within a Web page, advertisement delivery on a mobile terminal application (advertisement display space), and the like.

  The network 3 is a network including wired and wireless, and is, for example, a mobile phone line, WiFi (registered trademark), and the Internet.

(Hardware configuration)
FIG. 2 is a diagram illustrating a hardware configuration example of the mobile terminal 1 according to the embodiment of the present invention. Specifically, the hardware configuration is basically the same as that of a general personal computer, and as shown in the figure, a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, A RAM (Random Access Memory) 13, an input device 14, an output device 15, a communication device 16, and an HDD (Hard Disk Drive) 17 are included.

  The CPU 11 executes various programs and performs arithmetic processing. The ROM 12 stores a program necessary for startup. RAM13 memorize | stores the process in CPU11 temporarily, or memorize | stores data. The input device 14 is a keyboard or a mouse. The output device 15 is a display. The communication device 16 communicates with other devices via the network 3. The HDD 17 stores various data and programs.

  Since the mobile terminal 1 can be a smartphone, for example, the input device 14 can be realized by a touch panel that can detect tap coordinates (touch coordinates) on the screen instead of a keyboard and a mouse. In this case, the input operation on the portable terminal 1 is realized by a software key or the like.

(Software configuration)
FIG. 3 is a diagram illustrating a software configuration example of the mobile terminal 1 according to the first embodiment.

  The portable terminal 1 includes an operation unit 110, a contact surface shape acquisition unit 120, an advertisement operation determination unit 130, an operation invalidation unit 140, a display unit 150, a communication unit 160, and a storage unit 170 as functional units.

  The operation unit 110 has a function of realizing an operation function of the mobile terminal 1 and detecting and inputting a user input operation. As described above, the mobile terminal 1 according to the present embodiment is a smartphone, for example, and thus has a touch panel. Accordingly, the operation unit 110 detects taps, swipes, pinch operations, and the like on the screen as user input operations.

  When a user operation is input from the operation unit 110, the contact surface shape acquisition unit 120 has a function of acquiring the contact surface shape from the contact surface coordinates based on the input coordinates. Since the mobile terminal 1 according to the present embodiment is, for example, a smartphone, a tap, swipe, pinch operation, or the like on the screen is input as a user operation. That is, since a plurality of coordinate points are detected by the user's input operation, the contact surface shape acquisition unit 120 can acquire a figure formed by the coordinate group of the plurality of coordinate points as a contact surface shape. This point will be described later again.

  The advertisement operation determination unit 130 has a function of determining whether or not the user input operation on the screen is an operation on the advertisement displayed on the screen when the operation unit 110 detects the user input operation on the screen. doing. Whether or not the input operation is an operation for an advertisement displayed on the screen can be determined, for example, by determining whether or not the coordinates of the advertisement and the contact surface coordinates are superimposed.

  The operation invalidation unit 140 has a function of invalidating the user operation when the user input operation is an erroneous operation. Specifically, one is that when the contact surface shape formed from the input coordinates (contact surface coordinates) and the reference contact surface shape of the storage unit 170 are not the same or dissimilar, the input operation to the operation unit 110 is performed. Disable it. This point will be described later again.

  Note that, when the target of invalidation of the erroneous operation is limited to the tap operation for the advertisement displayed on the screen, the input operation determined to be the tap operation for the advertisement by the advertisement operation determination unit 130 is invalidated.

  Here, the operation invalidation is based on the premise that the mobile terminal 1 is in an operable state (for example, in use). The reason is that the present invention invalidates an erroneous operation (for example, erroneous tap) that occurs while the user is using the mobile terminal 1. For example, when the mobile terminal 1 is not in use because the mobile terminal 1 is stored in a bag or pocket, that is, when the mobile terminal 1 is in an unused state such as a standby state or a locked state, In the first place, it can be assumed that the operation itself has not been validated.

  The display unit 150 has a function of displaying display information such as a web page or an advertisement on the screen of the mobile terminal 1. In the present embodiment, as a specific method for displaying an advertisement on the mobile terminal 1, there are, for example, an advertisement display on a website and an advertisement display on a terminal application (advertisement display space).

  The communication unit 160 has a function for realizing a communication function. In the present embodiment, for example, the server 2 has a function of receiving display information such as a web page and an advertisement.

  The storage unit 170 has a function of storing a contact surface shape (referred to as a reference contact surface shape) based on a user's normal input operation. The user inputs in advance the user's normal tap, swipe, pinch operation, and the like to the mobile terminal 1 in advance. Since a plurality of coordinate points are detected by these operations, the storage unit 170 stores a figure formed by the coordinate group of the plurality of coordinate points as a normal contact surface coordinate of the user, that is, a reference contact surface shape. It is something to keep.

  Note that these functional units are realized by a computer program executed on hardware resources such as a CPU, a ROM, and a RAM of a computer constituting the portable terminal 1. However, these functional units may be read as “means”, “module”, “unit”, or “circuit”.

(Standard contact surface shape)
As described above, the user inputs (registers) his / her normal tap, swipe, pinch operation, and the like to the mobile terminal 1 in advance. Since a plurality of coordinate points are detected by these operations, a figure formed by the coordinate group of the plurality of coordinate points is stored in the storage unit 170 as a reference contact surface shape.

  FIG. 4 is a view for explaining a reference contact surface shape registration screen according to an embodiment of the present invention. On the registration screen, “Register your normal tap operation, swipe operation, and pinch operation. Enter the tap operation, swipe operation, and pinch operation in the frame of the screen in this order. Invalid operation invalidation determination Is used. ”Is displayed. The user inputs normal tap operation, swipe operation, and pinch operation in the frame of the screen according to the display.

  FIG. 5 is a diagram illustrating an example of a reference contact surface shape according to an embodiment of the present invention. (A) is data in which a user's normal tap operation is input from the registration screen. Specifically, a plurality of coordinate points where a user's finger (for example, forefinger) has touched the screen are detected by a tap operation. A figure formed by the coordinate group of the plurality of coordinate points is registered as a reference contact surface shape for tap operation.

  The same applies to the swipe operation and the pinch operation as shown in (b) and (c). That is, figures formed by coordinate groups of a plurality of coordinate points detected by the swipe operation and the pinch operation are registered as the reference contact surface shape for the swipe operation and the reference contact surface shape for the pinch operation, respectively.

  In this example, as an example, the user inputs an operation using the “index finger”. However, in addition to the “index finger”, for example, a “thumb” is often used for normal operations, so it is preferable to register an operation with the “thumb” together. Moreover, you may register operation with another finger | toe according to a user's utilization aspect.

  Further, even if the reference contact surface shape is not registered by the user, the default reference contact surface shape is stored in advance in the storage unit 170 so that the reference contact surface shape can be used. It is also possible. The universal reference contact surface shape is a contact surface shape obtained by a general tap operation, swipe operation, and pinch operation by an average user.

  In addition to the reference contact surface shape for everyone, a more detailed reference contact surface shape (referred to as a user attribute-specific reference contact surface shape) can be stored in the storage unit 170 for each user attribute. User attributes include, for example, sex, age, operation proficiency level, and the like. Therefore, if the mobile terminal 1 acquires the user attribute of the user of the mobile terminal 1, the mobile terminal 1 adopts the user attribute-specific reference contact surface shape corresponding to the acquired user attribute as the reference contact surface shape. The acquisition method of the user attribute of the user who uses the portable terminal 1 may be acquired from various servers or the like by profile information or the like, or may be acquired from profile information or the like held in advance in the portable terminal 1. (User attribute acquisition means).

  In addition, even when the reference contact surface shape is not explicitly registered by the user, the contact surface shape obtained by the user's tap operation, swipe operation, and pinch operation for a certain period from the start of use of the mobile terminal 1. By learning the sample data, it may be automatically registered as the reference contact surface shape of the user.

<Usage example>
Next, a usage example of the mobile terminal 1 according to the present embodiment will be specifically described.

  FIG. 6 is a diagram illustrating a usage example of the mobile terminal 1 according to the embodiment of the present invention.

  FIG. 6A shows a state in which the user operates to call a web page “XXX Blog” from a bookmark on the screen of the mobile terminal 1. In addition, as a usage environment of the portable terminal 1, it is assumed that the user is using the portable terminal 1 while walking, for example.

  Here, at the timing when the user tries to tap the position of “XX Blog”, the finger slips by hitting or hitting a person, for example, where the position of “XXX Blog” should originally be tapped Suppose you have tapped another location. Specifically, for example, the user mistakenly taps the position of “XX newspaper”, taps the “close” position, or taps the position of the banner advertisement.

  In this case, according to the conventional portable terminal, since an operation is input to the tap position, it goes without saying that processing corresponding to the input is executed. For example, if a tap operation to the position “XX newspaper” is input, a process for calling the Web page “XX newspaper” is executed, and if a tap operation to the “close” position is input. Then, a process of closing the currently displayed web page is executed. Further, when a tap operation to a hyperlink (for example, “Sports Day”) or a banner advertisement position is input, a process for calling a link page is executed. In such a case, when the user recognizes that an unintended process has been executed due to an erroneous operation, the user must perform an operation such as a screen recovery operation. After that, the original operation for calling the Web page “XXX Blog” from the bookmark must be performed again.

  FIG. 6B shows a state in which the user browses a Web page on the screen of the mobile terminal 1. As a usage environment of the mobile terminal 1, the user can use the mobile terminal 1 in a train, for example. I use it.

  Here, while the user is browsing the currently displayed Web page, for example, the train slips greatly and the finger slips, and the user has no intention (intention) to perform a special operation. Operation). In such a case, when the user recognizes that an unintended screen scroll process has been executed due to an erroneous operation, the user must perform an operation such as a recovery operation to the original screen position.

  However, on the other hand, in the mobile terminal 1 according to the embodiment, such an erroneous operation is invalidated, and thus processing according to the input is not executed.

  FIG. 7 is a diagram illustrating an example of a contact surface shape according to an embodiment of the present invention. As described above, for example, when a finger slips by hitting or hitting a person and an erroneous operation is input to the mobile terminal 1, the contact surface shape based on the erroneous operation may be an irregular shape or the like. It is quite different from the normal contact surface shape of the user.

  For example, the contact surface shape detected based on the tap misoperation of FIG. 7A is clearly different from the normal contact surface shape registered in advance (for example, FIG. 5A) (same or same). Not similar). Further, for example, the contact surface shape detected based on the erroneous swipe operation in FIG. 7B is clearly different from the normal contact surface shape registered in advance (for example, FIG. 5B) ( Not identical or similar).

  That is, when the contact surface shape detected based on the user's input operation is not the same as or not similar to the normal contact surface shape, the mobile terminal 1 according to the present embodiment regards the input operation as an erroneous operation. The input operation is invalidated.

  Therefore, for example, even if a finger slips by hitting or hitting a person and a tap operation to the position of “XX newspaper” is input, a process of calling the Web page of “XX newspaper” is executed. Not. In other words, since the screen state before the erroneous tap, which is an erroneous operation, is maintained, the user can perform the tap operation to the originally intended “XX Blog” position without performing troublesome operations such as screen recovery operations. Is possible. Even if a swipe operation is input, the screen scroll process is not executed. That is, since the screen state before the erroneous swipe that is an erroneous operation is maintained, the user can continue to view the screen.

<Operation>
Next, the processing operation of the mobile terminal 1 according to the first embodiment will be described. FIG. 8 is a flowchart illustrating a processing example of the mobile terminal 1 according to the first embodiment. In addition, as an application scene, the scene where a user browses a web page using the portable terminal 1 is assumed (for example, refer FIG. 6).

  S1: First, the mobile terminal 1 determines whether or not the use of the mobile terminal 1 is started (whether or not it is in use). The present invention is based on the premise that the mobile terminal 1 is in use because the user invalidates an erroneous operation (for example, erroneous tap) while the mobile terminal 1 is in use. In the present embodiment, the term “in use” means that the user has become operable. However, when the power is turned on or the use is limited to browsing information by the browser, the browser is used. It may be when the is activated.

  S2: The mobile terminal 1 (the operation unit 110) determines whether or not a user input operation is detected. That is, the operation waits until a user input operation is received. Here, as described above, the mobile terminal 1 according to the present embodiment is, for example, a smartphone, and thus has a touch panel. Accordingly, the operation unit 110 detects taps, swipes, pinch operations, and the like on the screen as user input operations.

  S3: When the user's input operation is detected by the operation detection unit 110, the mobile terminal 1 (advertisement operation determination unit 130) is an input operation (especially a tap operation) for an advertisement displayed on the screen. It is determined whether or not there is. Specifically, whether or not the input operation is an operation for an advertisement displayed on the screen by determining whether or not the tapped coordinate and the advertisement display coordinate range overlap (superimpose). Can be determined. If the operation is not an advertisement, the process proceeds to S7. Note that S3 can be omitted when the target of invalidation of the erroneous operation is not limited to the operation on the advertisement displayed on the screen. That is, the process may proceed to S4 after S2.

  S4: When the user's operation is input, the mobile terminal 1 (contact surface shape acquisition unit 120) acquires the contact surface coordinates based on the input coordinates that are input. Since the mobile terminal 1 according to the present embodiment is, for example, a smartphone, a tap, swipe, pinch operation, or the like on the screen is input as a user operation. That is, since a plurality of coordinate points are detected by the user's input operation, the contact surface shape acquisition unit 120 can acquire a figure formed by the coordinate group of the plurality of coordinate points as a contact surface shape.

  S5: The mobile terminal 1 (operation invalidation unit 140) has a contact surface shape formed from the input coordinates (contact surface coordinates) acquired in S4 and a reference contact surface shape of the storage unit 170 that are not identical and dissimilar. Check if there is any.

  Here, for example, as an example of the contact surface shape, reference is made to FIG. FIG. 7A is referred to as an example of the reference contact surface shape of the storage unit 170. Comparing both contact surface shapes, the contact surface shapes are clearly different, and it can be determined that they are non-identical and dissimilar.

  Note that the reference contact surface shape of the storage unit 170 may store a plurality of reference contact surface shapes as shown in FIGS. In such a case, it is compared with all the reference contact surface shapes, and it is determined whether or not any reference contact surface shape is non-identical and dissimilar.

  The determination process may be executed by using an image matching processing technique. Moreover, what is necessary is just to follow an image collation processing technique also about determining to dissimilarity in what range. This determination process will be supplemented later.

  S6: If the mobile terminal 1 (operation invalidation unit 140) determines that the contact surface shape acquired in S4 and the reference contact surface shape in the storage unit 170 are not the same and dissimilar, the input is performed in S2 Disable user input operations.

  For example, when a finger slips by hitting or hitting a person and an erroneous operation is input to the mobile terminal 1, the contact surface shape based on the erroneous operation is highly likely to be an irregular shape or the like. Compared with the contact surface shape, there is a clear difference. Therefore, the operation invalidation unit 140 determines whether the contact surface shape acquired in S4 and the reference contact surface shape of the storage unit 170 are non-identical and dissimilar. The user's input operation input in S2 is regarded as an erroneous operation instead of a normal input operation, and the user's input operation is invalidated.

  S7: On the other hand, when the operation target is not an advertisement (S3), or when the contact surface shape acquired in S4 and the reference contact surface shape of the storage unit 170 are not identical and dissimilar (when identical or similar), The user input operation input in S2 is regarded as a normal input operation, and the input operation is input (executed).

  S8: The mobile terminal 1 determines whether or not the mobile terminal 1 has been used. If the use is not finished, the process returns to S2.

  As described above, the mobile terminal 1 according to the first embodiment compares the contact surface shape based on the user's input operation with the reference contact surface shape registered in advance by the user during the normal operation, and the contact surface shape is the reference contact surface. When the shapes are not identical and dissimilar (when they are not identical or similar), the user's input operation is regarded as an erroneous operation and the input operation is invalidated. Thereby, the user can avoid troublesome operations based on an erroneous operation such as a screen recovery operation.

  In particular, when a tap operation is performed on an advertisement displayed on the screen, communication to the link destination occurs and screen transition to the advertisement site occurs. To recover the operation, it is necessary to press the “Return” button on the screen, but sometimes the “Return” button cannot be pressed during communication to the link destination. Troublesome operations can occur. Therefore, as described above, when the target of invalidation of the erroneous operation is limited to the tap operation for the advertisement displayed on the screen, the input operation determined by the advertisement operation determination unit 130 as the tap operation for the advertisement is performed. It can also be invalidated as a target.

[Embodiment 2]
In the first embodiment described above, an erroneous operation is determined based on the contact surface shape. On the other hand, in this embodiment, an erroneous operation is determined based on the coordinate change speed.

  FIG. 9 is a diagram illustrating a software configuration example of the mobile terminal 1 according to the second embodiment. Compared to FIG. 3, the mobile terminal 1 has a coordinate change speed acquisition unit 180 instead of the contact surface shape acquisition unit 120 as a functional unit. In addition, the storage unit 170 stores a reference coordinate change speed instead of the reference contact surface shape.

  When the user's operation is input from the operation unit 110, the coordinate change speed acquisition unit 180 changes the coordinate from the contact surface coordinates based on the input coordinates and the time (or time interval) when each contact surface coordinate is detected. It has a function to acquire speed.

  For example, in the case of a swipe operation, an operation is performed so that the finger slides on the screen. Therefore, when the contact surface coordinates are detected, the contact is made continuously with the first finger contact point (starting point coordinate) as the starting point. Coordinates are detected one after another. For this reason, in the case of a normal swipe operation, the coordinate change speed is calculated using the starting point coordinates as the start point and an index indicating the speed at which the continuously touched coordinates are successively detected.

  The same applies to the tap operation. When a finger is tapped on the screen, but the contact surface coordinates are detected, the first finger contact point (starting point coordinate = for example, center point, etc.) is used as a starting point and continuously spread around the starting point coordinate. Touched coordinates are detected one after another. For this reason, in the case of a normal tap operation, the coordinate change speed is used as an index indicating the speed at which coordinates that are continuously touched so as to spread around the start point coordinates are detected one after another, starting from the start point coordinates. Is calculated.

  The reference coordinate change speed is a coordinate change speed (referred to as a reference coordinate change speed) based on a user's normal input operation. Similar to the above-described reference contact surface shape, the user inputs his normal tap, swipe, pinch operation, and the like to the mobile terminal 1 in advance (see, for example, FIG. 4). At this time, the storage unit 170 calculates a coordinate change rate based on these operations, and stores the calculated normal coordinate change rate of the user, that is, a reference coordinate change rate as a calculation.

  For the sake of simplicity, the reference coordinate change speed may be a speed between two points, for example, a contact point (starting point coordinate) of the first finger and a contact point (final coordinate) where the finger is finally released. Further, more finely, for example, with the first finger contact point (starting point coordinate) as the starting point, the coordinates that are continuously touched are set to the speeds between the respective coordinates that are successively detected, and finally the finger is released. It is good also as speed to a contact point (final coordinate).

  Further, even if the reference coordinate change speed is not registered by the user, the standard contact surface shape for everyone is stored in advance in the storage unit 170 so that the reference coordinate change speed can be used. It is also possible.

  Further, in addition to the reference contact surface shape for everyone, it is also possible to store in the storage unit 170 a more detailed reference coordinate change speed condition (referred to as a user attribute-specific reference coordinate change speed) for each user attribute. The acquisition method of the user attribute of the user who uses the portable terminal 1 may be acquired from various servers or the like by profile information or the like, or may be acquired from profile information or the like held in advance in the portable terminal 1. .

  Further, even when the reference coordinate change speed is not explicitly registered by the user, the coordinate change speed obtained by the user's tap operation, swipe operation, and pinch operation for a certain period from the start of use of the mobile terminal 1. It may be automatically registered as the reference coordinate change speed of the user by learning the sample data.

(Operation)
Next, the processing operation of the mobile terminal 1 according to the second embodiment will be described. FIG. 10 is a flowchart illustrating a processing example of the mobile terminal 1 according to the present embodiment. Compared with FIG. 8, S4 is changed to S4-2, and S5 is changed to S5-2. Below, it demonstrates centering around the said step.

  S4-2: When the user's operation is input, the mobile terminal 1 (coordinate change speed acquisition unit 180) receives each contact surface coordinate based on the input coordinate and the time (or time interval) when each contact surface coordinate is detected. From this, the coordinate change speed is obtained. Since the mobile terminal 1 according to the present embodiment is, for example, a smartphone, a tap, swipe, pinch operation, or the like on the screen is input as a user operation. That is, since a plurality of coordinate points are continuously detected as time passes by the user's input operation, the coordinate change speed acquisition unit 180 detects each contact surface coordinate and each contact surface coordinate based on the input coordinates. From the time (or time interval), the coordinate change speed can be acquired.

  S5-2: The mobile terminal 1 (operation invalidation unit 140) determines that the coordinate change rate calculated from the input coordinates (each contact surface coordinate) acquired in S4-2 and the reference coordinate change rate of the storage unit 170 are not. It is determined whether or not they are the same value and a non-approximate value.

  For example, when a finger slips by hitting or hitting a person and an erroneous operation is input to the mobile terminal 1, the speed at which the erroneous operation is input is faster than the speed at which the normal operation is input. Conceivable. Specifically, the touch operation suddenly touches at the timing of hitting a person or the finger slips on the screen, so the input operation input in this case is the normal reference coordinate change speed. In comparison, it is considered that a large coordinate change speed is detected.

  Therefore, in the mobile terminal 1 (operation invalidation unit 140), the coordinate change rate calculated from the input coordinates (each contact surface coordinate) acquired in S4-2 and the reference coordinate change rate in the storage unit 170 are not the same value. If it is a non-approximate value, the user's input operation input in S2 is regarded as an erroneous operation. That is, in this case, the process proceeds to S6, and the portable terminal 1 (operation invalidation unit 140) invalidates the user's input operation input in S2.

  As described above, in the mobile terminal 1 according to the second embodiment, the coordinate change speed calculated from the input coordinates based on the user's input operation and the reference coordinate change speed based on the normal operation of the user are non-identical and non-approximate values. In some cases, the user's input operation is regarded as an erroneous operation, and the input operation is invalidated. As a result, as in the first embodiment, the user can avoid troublesome operations based on erroneous operations such as a screen recovery operation.

[Embodiment 3]
In the first embodiment described above, an erroneous operation is determined based on the contact surface shape. In the second embodiment, an erroneous operation is determined based on the coordinate change speed. On the other hand, in the third embodiment, an erroneous operation is determined based on the contact surface shape and the coordinate change speed.

  FIG. 11 is a diagram illustrating a software configuration example of the mobile terminal 1 according to the third embodiment. Compared to FIG. 3, the mobile terminal 1 further includes a coordinate change speed acquisition unit 180 as a functional unit. Further, the storage unit 170 stores a reference coordinate change speed.

  When the user's operation is input from the operation unit 110, the coordinate change speed acquisition unit 180 changes the coordinate from the contact surface coordinates based on the input coordinates and the time (or time interval) when each contact surface coordinate is detected. It has a function to acquire speed. As described above, the reference coordinate change speed is a coordinate change speed (referred to as a reference coordinate change speed) based on a user's normal input operation. The storage unit 170 stores the normal coordinate change speed of the user, that is, the reference coordinate change speed as a calculation.

(Operation)
Next, the processing operation of the mobile terminal 1 according to the third embodiment will be described. FIG. 12 is a flowchart illustrating a processing example of the mobile terminal 1 according to the third embodiment. Note that S4-2 and S5-2 are added as compared to FIG. Below, it demonstrates centering around the said step.

  S4: When the user's operation is input, the mobile terminal 1 (contact surface shape acquisition unit 120) acquires the contact surface coordinates based on the input coordinates that are input.

  S4-2: Also, when the user's operation is input, the mobile terminal 1 (coordinate change speed acquisition unit 180) receives each contact surface coordinate based on the input coordinate and the time (or time) when each contact surface coordinate is detected. The coordinate change speed is obtained from (interval).

  S5: The mobile terminal 1 (operation invalidation unit 140) has a contact surface shape formed from the input coordinates (contact surface coordinates) acquired in S4 and a reference contact surface shape of the storage unit 170 that are not identical and dissimilar. Judge whether there is.

  Here, if the contact surface shape formed from the input coordinates (contact surface coordinates) acquired in S4 and the reference contact surface shape of the storage unit 170 are not the same and not similar (if they are the same or similar), S5- Go to step 2.

  S5-2: The mobile terminal 1 (operation invalidation unit 140) determines that the coordinate change rate calculated from the input coordinates (each contact surface coordinate) acquired in S4-2 and the reference coordinate change rate of the storage unit 170 are not. It is determined whether or not they are the same value and a non-approximate value. The reason is as follows.

  In S5, based on the contact surface shape, it is determined whether or not the input operation of the input user is an erroneous operation. However, exceptionally, even if the contact surface shape formed from the input coordinates (contact surface coordinates) acquired in S4 and the reference contact surface shape of the storage unit 170 are the same or similar, the input user The input operation may be an erroneous operation. Specifically, the contact surface shape formed from the input coordinates (contact surface coordinates) of the input operation of the input user is actually the same as the reference contact surface shape or accidentally even though it is actually an erroneous operation. This is the case.

  If such a case exists, it cannot be determined as an erroneous operation only with S5. Therefore, in S5-2, it is determined whether the coordinate change speed calculated from the input coordinates (each contact surface coordinate) and the reference coordinate change speed in the storage unit 170 are non-identical values and non-approximate values.

  The portable terminal 1 (operation invalidation unit 140) determines that the coordinate change speed calculated from the input coordinates (each contact surface coordinate) acquired in S4-2 and the reference coordinate change speed of the storage unit 170 are not the same value. If it is a non-approximate value, even if it is the same or similar to the reference contact surface shape, the user's input operation input in S2 is regarded as an erroneous operation. That is, in this case, the process proceeds to S6, and the portable terminal 1 (operation invalidation unit 140) invalidates the user's input operation input in S2.

  As described above, the mobile terminal 1 according to the third embodiment compares the contact surface shape based on the user's input operation with the reference contact surface shape registered in advance by the user during the normal operation, and the contact surface shape is the reference contact surface. Even if the shape is the same as or similar to the shape, if the coordinate change speed calculated from the input coordinates and the reference coordinate change speed based on the normal operation of the user are non-identical and non-approximate values, The input operation is regarded as an erroneous operation, and the input operation is invalidated. Thereby, it is possible to invalidate an erroneous operation with higher accuracy.

[Embodiment 4]
In the above-described first to third embodiments, an erroneous operation is determined on the mobile terminal 1 side. On the other hand, in the fourth embodiment, an erroneous operation function is not performed on the mobile terminal 1 side, and an erroneous operation is determined on the server side.

(Network configuration)
FIG. 13 is a network configuration diagram according to the fourth embodiment. Compared to FIG. 1, an erroneous operation determination server 4 is further connected.

  The erroneous operation determination server 4 is a server that provides erroneous operation determination information to the mobile terminal 1 of the user. Specifically, when an erroneous operation determination request (including a user ID, a contact surface shape, etc.) is received from the mobile terminal 1, an erroneous operation determination is performed using a reference contact surface shape registered in advance for each user ID. Returns the judgment result. On the other hand, the mobile terminal 1 invalidates the input operation based on the determination result of the erroneous operation determination.

(Software configuration)
FIG. 14 is a diagram illustrating a software configuration example of the mobile terminal 1 and the erroneous operation determination server 4 according to the fourth embodiment. Compared with FIG. 3, as an overview, the erroneous operation determination performed by the operation invalidation unit 140 of the mobile terminal 1 is configured as a function performed by the erroneous operation determination server 4 side.

  First, the portable terminal 1 has a contact surface shape acquisition unit 120-2 and an operation invalidation unit 140-2 as points different from FIG.

  When a user operation is input from the operation unit 110, the contact surface shape acquisition unit 120-2 has a function of acquiring the contact surface shape from the contact surface coordinates based on the input coordinates. The contact surface shape acquisition unit 120-2 passes the acquired contact surface shape to the communication unit 160 together with the user ID of the user of the mobile terminal 1 in order to transmit an erroneous operation determination request to the erroneous operation determination server 4.

  The operation invalidation unit 140-2 has a function of invalidating the user operation when the erroneous operation determination result of the erroneous operation determination server 4 is “erroneous operation”.

  The communication unit 160 communicates with the erroneous operation determination server 4 and receives transmission of an erroneous operation determination request and the determination result.

  On the other hand, the erroneous operation determination server 4 includes a contact surface shape acquisition unit 410, an erroneous operation determination unit 420, a communication unit 430, and a storage unit 440.

  The contact surface shape acquisition unit 410 acquires the user ID and the contact surface shape included in the erroneous operation determination request from the mobile terminal 1.

  The erroneous operation determination unit 420 performs erroneous operation determination. Specifically, it is determined whether or not the contact surface shape included in the erroneous operation determination request and the reference contact surface shape of the storage unit 440 are non-identical or dissimilar. The determination result of the erroneous operation determination is passed to the communication unit 430 in order to respond to the mobile terminal 1. The determination result is either “erroneous operation” or “normal operation”.

  The communication unit 430 communicates with the mobile terminal 1 to receive an erroneous operation determination request and transmit the determination result.

  The storage unit 440 has a function of storing a reference contact surface shape based on a user's normal input operation. The user inputs in advance the user's normal tap, swipe, pinch operation, and the like to the mobile terminal 1 in advance. Since the storage unit 440 detects a plurality of coordinate points by these operations, the mobile terminal uses the figure formed by the coordinate group of the plurality of coordinate points as the normal contact surface coordinates of the user, that is, the reference contact surface shape. 1 is received and stored.

  In the fourth embodiment, the erroneous operation determination server 4 will be described as performing an erroneous operation based on the contact surface shape (corresponding to the first embodiment). However, the erroneous operation determination server 4 performs not only the contact surface shape but also an erroneous operation determination based on the coordinate change speed (corresponding to the second embodiment) and an erroneous operation determination based on the contact surface shape and the coordinate change speed (corresponding to the third embodiment). Obviously you can.

<Operation>
(Registration operation of reference contact surface shape)
As described above, the user inputs (registers) his / her normal tap, swipe, pinch operation, and the like to the mobile terminal 1 in advance. Since a plurality of coordinate points are detected by these operations, a figure formed by the coordinate group of the plurality of coordinate points is stored in the storage unit 440 of the erroneous operation determination server 4 as a reference contact surface shape.

  FIG. 15 is a flowchart illustrating an example of the registration process of the reference contact surface shape according to the first embodiment. In addition, as an application scene, the scene where a user performs registration operation of a semi-contact surface shape beforehand using the portable terminal 1 is assumed (for example, refer FIG. 4).

  S21: The portable terminal 1 (operation unit 110) determines whether or not a user input operation is detected. That is, the operation waits until a user input operation is received. Since the mobile terminal 1 is, for example, a smartphone, the operation unit 110 detects taps, swipes, pinch operations, and the like on the screen as user input operations.

  S22: When the user's operation is input, the mobile terminal 1 (contact surface shape acquisition unit 120-2) acquires the contact surface coordinates (reference contact surface coordinates) based on the input coordinates.

  S23: The portable terminal 1 (contact surface shape acquisition unit 120-2) transmits the reference contact surface shape registration request to the erroneous operation determination server 4, and thus the acquired contact surface shape together with the user ID of the user of the mobile terminal 1. The data is passed to the communication unit 160. The portable terminal 1 (communication unit 160) transmits a registration request including the user ID of the user and the acquired contact surface shape to the erroneous operation determination server 4.

  S24: On the other hand, when the erroneous operation determination server 4 (contact surface shape acquisition unit 410) receives the registration request from the mobile terminal 1 via the communication unit 430, the received user ID and the contact surface shape are associated with each other, The reference contact surface shape is registered in the storage unit 440 (see, for example, FIG. 5).

  S25: The erroneous operation determination server 4 sends a registration completion response to the mobile terminal 1.

  S26: The portable terminal 1 (the operation unit 110) receives the registration completion, and ends the registration process of the reference contact surface shape.

(Processing operation on the mobile terminal 1 side)
Next, the processing operation of the mobile terminal 1 according to the fourth embodiment will be described. FIG. 16 is a flowchart illustrating a processing example of the mobile terminal 1 according to the fourth embodiment. In addition, as an application scene, the scene where a user browses a web page using the portable terminal 1 is assumed (for example, refer FIG. 6). Note that S4-3, S4-4, and S4-5 are added compared to FIG. Below, it demonstrates centering around the said step.

  S4: When the user's operation is input, the mobile terminal 1 (contact surface shape acquisition unit 120) acquires the contact surface coordinates based on the input coordinates that are input.

  S4-3: The mobile terminal 1 (contact surface shape acquisition unit 120-2) transmits an erroneous operation determination request including the user ID of the user of the mobile terminal 1 and the acquired contact surface shape to the erroneous operation determination server 4.

  S4-4: The mobile terminal 1 (operation invalidation unit 140) determines whether or not the determination result is received within a predetermined time (predetermined value) as a response to the erroneous operation determination request. If received within a certain time, the process proceeds to S4-5. On the other hand, if the determination result is not received within a certain time, it is treated as a time-out, and the process proceeds to S7 where the user's input operation is input. If the configuration waits for the determination result indefinitely, the operation on the portable terminal 1 side may be frozen during the standby time to avoid this. That is, even if it is an erroneous operation or a normal operation, the user's input operation is executed. In order to avoid user operation execution stress, the predetermined time (predetermined value) depends on the environment such as communication speed and server response capability, but it is desirable to reduce the value as much as possible.

  S4-5: When the determination result of the erroneous operation determination of the erroneous operation determination server 4 is “erroneous operation”, the mobile terminal 1 (operation invalidation unit 140-2) proceeds to S6 and invalidates the user operation. On the other hand, when the determination result of the erroneous operation determination of the erroneous operation determination server 4 is “normal operation”, the process proceeds to S7 and the user's input operation is input.

(Processing on the erroneous operation determination server 4 side)
Next, the processing operation of the erroneous operation determination server 4 according to the fourth embodiment will be described. FIG. 17 is a flowchart illustrating a processing example of the erroneous operation determination server 4 according to the fourth embodiment.

  S31: The erroneous operation determination server 4 determines whether or not an erroneous operation determination request is received from the mobile terminal 1, and starts an erroneous operation determination process when an erroneous operation determination request is received.

  S32: When the erroneous operation determination server 4 (contact surface shape acquisition unit 410) receives the erroneous operation determination request from the portable terminal 1, the user ID and the contact surface shape included in the erroneous operation determination request are acquired.

  S33: The erroneous operation determination server 4 (the erroneous operation determination unit 420) acquires the reference contact surface shape associated with the acquired user ID from the storage unit 440, and then the input coordinates (contact surface coordinates) acquired in S32. Whether or not the contact surface shape formed from and the reference contact surface shape of the storage unit 440 are non-identical and dissimilar is determined.

  S34: The erroneous operation determination server 4 (the erroneous operation determination unit 420) responds to the mobile terminal 1 with the determination result of the erroneous operation determination. Specifically, when it is determined that the contact surface shape and the reference contact surface shape are not the same and dissimilar, the determination result is “erroneous operation”.

  S35: On the other hand, when the erroneous operation determination server 4 (the erroneous operation determination unit 420) determines that the contact surface shape and the reference contact surface shape are not the same and dissimilar, the determination result is “normal operation”.

  The determination result is returned to the mobile terminal 1 and used to determine whether or not to invalidate the user's input operation (S4-5 in FIG. 16).

  As described above, the erroneous operation determination server 4 according to the fourth embodiment compares the contact surface shape based on the user's input operation with the reference contact surface shape registered in advance by the user during the normal operation, and the contact surface shape is the reference contact. When the surface shape is not the same and dissimilar (when not identical or similar), the user's input operation is determined to be an erroneous operation. The determination result is returned to the mobile terminal 1, and the mobile terminal 1 invalidates the input operation when the determination result of “erroneous operation” is returned. Thereby, the user can avoid troublesome operations based on an erroneous operation such as a screen recovery operation.

  In addition, even when the reference contact surface shape is not registered by the user, the reference contact surface shape for everyone is stored in advance in the storage unit 440 so that the reference contact surface shape can be used. It is also possible. In the fourth embodiment, the reference contact surface shapes of a plurality of users are registered together with the user IDs. Therefore, when the reference contact surface shapes of a plurality of users are used as sample data, a universal reference contact surface shape is calculated. It is suitable for. That is, even for a user who has not registered the reference contact surface shape by the user, the reliable reference contact surface shape for everyone can be used in erroneous operation determination.

  It is also possible to store in the storage unit 440 a more detailed reference contact surface shape (reference contact surface shape by user attribute) for each user attribute. In the fourth embodiment, the reference contact surface shapes of a plurality of users are registered together with the user IDs, but the user attributes of the users (known information) are also known by the user IDs. When the contact surface shape is used as sample data, it is suitable for calculating the reference contact surface shape by user attribute. That is, even for a user who has not registered the reference contact surface shape by the user, a reliable user attribute-specific reference contact surface shape suitable for the user attribute of the user can be used in the erroneous operation determination.

  In addition, even when the reference contact surface shape is not explicitly registered by the user, the contact surface shape obtained by the user's tap operation, swipe operation, and pinch operation for a certain period from the start of use of the mobile terminal 1. By learning the sample data, it may be automatically registered as the reference contact surface shape of the user.

  In the fourth embodiment, the erroneous operation determination server 4 has been described as performing an erroneous operation based on the contact surface shape (corresponding to the first embodiment). However, the erroneous operation determination server 4 performs not only the contact surface shape but also an erroneous operation determination based on the coordinate change speed (corresponding to the second embodiment) and an erroneous operation determination based on the contact surface shape and the coordinate change speed (corresponding to the third embodiment). Obviously you can.

[Supplement 1]
Here, for example, for a user who has registered a normal operation but has a complicated input operation, the contact surface shape based on the user's input operation is determined to be non-identical and dissimilar to the reference contact surface shape. It is assumed that the input operation is invalidated.

  However, the cause is, for example, that the input operation is merely miscellaneous, and the user himself / herself inputs the input operation according to his / her intention. Therefore, when the input operation is invalidated, the intended operation is executed. It may not be.

  Therefore, for a user with a complicated input operation, the operation invalidation unit 140 may slightly enlarge the range determined to be similar when comparing the contact surface shape and the reference contact surface shape (similarity determination is performed). Sweeten). In this case, the mobile terminal 1 has setting means for enlarging (or reducing) the range determined to be similar. In this way, even if the user has a complicated input operation, it is determined that the operation is a normal normal operation if it is a little, so that the operation intended by the user can be executed.

  Regarding the second and third embodiments, similarly, the mobile terminal 1 has setting means for enlarging (or reducing) the approximate value when comparing the coordinate change speed and the reference coordinate change speed.

[Supplement 2]
In S5 of FIG. 8, the mobile terminal 1 (operation invalidation unit 140) determines the contact surface shape formed from the input coordinates (contact surface coordinates) acquired in S4 of FIG. 8 and the reference contact surface shape of the storage unit 170. Were checked to determine whether they were non-identical and dissimilar. Hereinafter, the similarity determination method will be described.

(1) Use of Jaccard coefficient
The Jaccard coefficient is a coefficient representing the degree of co-occurrence of two sets, that is, how similar they are.

First, contact coordinate sets SA and SB of all points on the contact surfaces A and B are obtained. The contact surface A may be the contact surface shape acquired in S <b> 4 and the contact surface B may be the reference contact surface shape of the storage unit 170.
SA = {(XA1, YA1), (XA2, YA2), (XA3, YA3), ..., (XAnA, YAnA)}
SB = {(XB1, YB1), (XB2, YB2), (XB3, YB3), ..., (XBnB, YBnB)}
Next, in order to consider the starting point coordinates, the vectors are converted into vector sets VA and VB from the starting point coordinates which are the contact points of the first finger.
VA = {(xA1, yA1), (xA2, yA2), (xA3, yA3), ..., (xAnA, yAnA)}
VB = {(xB1, yB1), (xB2, yB2), (xB3, yB3), ..., (xBnB, yBnB)}
Then, the Jaccard coefficient: J = | VA∧VB | / | VA∨VB |
| VA∧VB |: Number of vectors common to A and B (product set)
| VA∨VB |: Number of vectors A or B (union set)
The Jaccard coefficient takes a value of 0 to 1, and the greater the value, the greater the similarity. The value is 1 for a perfect match, and 0 for all different values.

  Therefore, assuming that the predetermined threshold value used for the determination is 0.8, for example, when the Jaccard coefficient> 0.8, it is determined that they are similar. In other words, when the Jaccard coefficient <= 0.8, it can be determined as dissimilar. When the Jaccard coefficient = 1, it can be determined that they are the same.

(2) Use of Simpson coefficient
The Simpson coefficient is also a coefficient representing how similar.

First, contact coordinate sets SA and SB of all points on the contact surfaces A and B are obtained. The contact surface A may be the contact surface shape acquired in S <b> 4 and the contact surface B may be the reference contact surface shape of the storage unit 170.
SA = {(XA1, YA1), (XA2, YA2), (XA3, YA3), ..., (XAnA, YAnA)}
SB = {(XB1, YB1), (XB2, YB2), (XB3, YB3), ..., (XBnB, YBnB)}
Next, in order to consider the starting point coordinates, the vectors are converted into vector sets VA and VB from the starting point coordinates which are the contact points of the first finger.
VA = {(xA1, yA1), (xA2, yA2), (xA3, yA3), ..., (xAnA, yAnA)}
VB = {(xB1, yB1), (xB2, yB2), (xB3, yB3), ..., (xBnB, yBnB)}
Then, the Simpson coefficient: J = | VA∧VB | / min (| VA |, | VB |) is obtained.
| VA∧VB |: Number of vectors common to A and B
min (| VA |, | VB |): Number of vectors in the set with the smaller number of elements in A and B
The Simpson coefficient takes a value of 0 to 1, and the greater the value, the greater the similarity. The value is 1 for a perfect match, and 0 for all different values.

  Therefore, if the predetermined threshold value used for the determination is 0.8, for example, it is determined that they are similar when the Simpson coefficient> 0.8. In other words, when the Simpson coefficient <= 0.8, it can be determined as dissimilar. Further, when the Simpson coefficient = 1, it can be determined that they are the same.

(3) Use of Dice coefficient
The Dice coefficient is also a coefficient representing how similar.

First, contact coordinate sets SA and SB of all points on the contact surfaces A and B are obtained. The contact surface A may be the contact surface shape acquired in S <b> 4 and the contact surface B may be the reference contact surface shape of the storage unit 170.
SA = {(XA1, YA1), (XA2, YA2), (XA3, YA3), ..., (XAnA, YAnA)}
SB = {(XB1, YB1), (XB2, YB2), (XB3, YB3), ..., (XBnB, YBnB)}
Next, in order to consider the starting point coordinates, the vectors are converted into vector sets VA and VB from the starting point coordinates which are the contact points of the first finger.
VA = {(xA1, yA1), (xA2, yA2), (xA3, yA3), ..., (xAnA, yAnA)}
VB = {(xB1, yB1), (xB2, yB2), (xB3, yB3), ..., (xBnB, yBnB)}
Then, a Dice coefficient: S = 2 | VA∧VB | / (| VA | + | VB |) is obtained.
| VA∧VB |: Number of vectors common to A and B
| VA | + | VB |: Number of vectors in A + number of vectors in B
The Dice coefficient takes a value of 0 to 1, and the greater the value, the greater the similarity. The value is 1 for a perfect match, and 0 for all different values.

  Therefore, if the predetermined threshold value used for the determination is 0.8, for example, it is determined that they are similar when the Dice coefficient> 0.8. Conversely, when the Dice coefficient <= 0.8, it can be determined as dissimilar. Further, when the Dice coefficient = 1, it can be determined that they are the same.

  By using any of the above (1) Jaccard coefficient, (2) Simpson coefficient, and (3) Dice coefficient, a contact surface shape formed from the input coordinates (contact surface coordinates) acquired in S4 of FIG. It can be determined whether or not the reference contact surface shape of the storage unit 170 is non-identical and dissimilar.

Further, when considering the order of finger contact points (converted into vectors), an index for evaluating the correlation of the order of sets having different numbers of elements may be used. For details, the following can be referred to, for example.
