Abstract

PROBLEM TO BE SOLVED: To accurately discriminate an effective operation and erroneous detection when an end area is touched.SOLUTION: When there is only one touch area and end coordinate points at the peripheral edge of a touch panel are included, and when there are a plurality of touch areas, at least one touch area includes the end coordinate points, and the maximum distance between one of the end coordinate points and the coordinate point of the other touch area is shorter than a prescribed distance set beforehand, discrimination of an input operation is put on hold (S106, S111), and when a new touch operation is performed after it is put on hold, the input operation is discriminated on the basis of the touch area that is put on hold and the new touch area.

Description

  The present invention relates to an input device using a touch panel, a mobile terminal device such as a mobile phone provided with such an input device, and an input processing method using such an input device.

  As a touch panel input device provided to be overlapped on a display screen of a mobile terminal device or the like, a device that can detect even when a plurality of areas are touched at the same time, for example, by detecting a change in capacitance is known. (For example, refer to Patent Document 1).

  Regarding the operation of the camera, there is also known a technique for preventing erroneous detection by enabling the touch of the fingertip when a plurality of areas are touched at the fingertip and the portion near the base of the finger. In this technique, in order to recognize the direction of the fingertip, the posture of the camera is detected by a gyro sensor, and it is estimated which hand is operated with the left or right hand (see, for example, Patent Document 2).

  Furthermore, in principle, touches that have a center of gravity near the edge of the operation area are ignored, and if they are recognized as part of a gesture operation such as a so-called drag gesture or pinch gesture, they are enabled to prevent false detection. Meanwhile, a technique for expanding the function of the input device is also known (see, for example, Patent Document 3).

JP 2002-342033 A Japanese Patent Application No. 2008-308371 Japanese Patent Application No. 2008-336240

  However, the technique for enabling the touch of the fingertip as in Patent Document 2 cannot be applied to an operation by intentionally touching a plurality of areas, and an attitude detection sensor such as a gyro sensor is essential. Therefore, the manufacturing cost is high.

  In addition, in the technique such as Patent Document 3, in principle, when the center of gravity of the touch is in the vicinity of the end, the touch is ignored, so the touch unintended by the user extends over a wide range and the center of gravity is in the vicinity of the end. In the case of being located on the inner side, erroneous detection cannot be prevented. In addition, an operation that is not recognized as part of the gesture operation cannot be effectively processed.

  The present invention has been made in view of such a point, and an object thereof is to enable more accurate discrimination between an effective operation and a false detection even when an end region of the touch panel input device is touched. It is in.

The first invention is
A touch panel input device that detects a touch area of a touch panel provided on a display unit and discriminates an input operation based on the touch area,
A touch discriminating unit that discriminates an input operation based on the touch area;
An end determination unit that determines whether or not the touch region includes an end coordinate point in an end region of the periphery of the touch panel;

A post-holding touch determination unit that determines an input operation based on the touch area put on hold and the new touch area when a new touch operation is made after the hold;
It is characterized by having.

  As a result, when the edge area on the periphery of the touch panel is touched, the determination of the input operation based on the touch area is suspended, and the input operation can be determined based on the new touch area later. For example, it is possible to more appropriately determine whether the touch of the region is an erroneous operation in which the base of the finger or the belly is unintentionally touched or the introduction to the next operation such as multiple touches.

The second invention is
A touch panel input device according to a first invention,
The determination holding unit is a case where the new touch area after the holding includes an end coordinate point, and between any end coordinate point including the end coordinate point and the coordinate point of another touch area. When the maximum distance is smaller than a predetermined distance, the input operation determination is put on hold,
The post-holding touch determination unit is configured to determine an input operation based on the new touch area when the maximum distance is larger than a predetermined distance set in advance.

  As a result, when there is a possibility of erroneous operation including the touch made after the input operation determination is suspended, it is possible to determine the input operation based on the subsequent touch area. On the other hand, when there is a high possibility that the touch made after the input operation determination has been suspended is the intended operation, it becomes possible to determine the input operation based on the subsequent touch area, and malfunction due to the previous touch Is more appropriately prevented.

The third invention is
The touch panel input device according to any one of the first invention and the second invention,
The after-holding touch determination unit is configured to determine an input operation based on the new touch area when the new touch area after the holding does not include an end coordinate point. To do.

  As a result, when there is a high possibility that the touch made after the determination of the input operation is suspended is the intended operation, it becomes possible to determine the input operation based on the subsequent touch area. A malfunction caused by touch is prevented more appropriately.

The fourth invention is:
A touch panel input device according to any one of the first to third inventions,
The post-holding touch determination unit, based on the touch area and the movement, when the touch area put on hold and the new touch area after the hold move according to a preset rule. It is configured to discriminate an input operation.

  Thereby, the operation | movement according to what is called gesture operation etc. can be performed appropriately.

The fifth invention is:
A touch panel input device according to any one of the first to fourth inventions,
The touch determination unit includes a plurality of touch areas, at least one touch area includes an end coordinate point, and a maximum distance between any end coordinate point and a coordinate point of another touch area is set in advance. When the coordinate point of the other touch area is not an end coordinate point, the input operation is determined based on the other touch area when the distance is not less than a predetermined distance.

  Thereby, for example, it is possible to appropriately perform an operation by an intended touch while preventing an erroneous operation due to an unintentional contact with a base of the finger or an abdomen.

The sixth invention is:
A touch panel input device according to any one of the first to fifth inventions,
In the case where there is only one touch area and the end coordinate point is included, and the touch area moves at a speed higher than a predetermined speed, the touch determination section It is characterized by determining input operation based on it.

When moving according to the rule, the input operation is discriminated based on the touch area and the movement.

  As a result, operations corresponding to so-called gesture operations can be appropriately performed.

  In the present invention, even when a plurality of areas in the touch panel input device are touched, it is possible to more accurately determine an effective operation and a false detection.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a front view showing an external appearance of an example of a mobile terminal device 100 that includes a touch panel input device having a touch panel 112, such as a mobile phone or an information processing terminal. The touch panel 112 is provided over almost the entire surface of the main body 111 of the mobile terminal device 100. The end region 112b along the four sides of the outer edge, that is, the peripheral region of the touch panel 112, and the main region 112a inside the end region 112b. And have. As the touch panel 112, for example, a touch area discriminating device based on a change in capacitance is used. However, the method is not particularly limited as long as a plurality of touches can be detected, and other various types are used. May be.

  FIG. 2 is a block diagram illustrating a functional configuration related to a touch panel operation in the mobile terminal device 100. The control unit 121 (touch discrimination unit, end discrimination unit, discrimination hold unit, post-hold touch discrimination unit) is connected to the touch panel unit 122 having the display unit 122a and the operation unit 122b including the touch panel 112, and the storage unit 123. By executing the program stored in the storage unit 123, the display operation of the display unit 122a is controlled, the operation performed on the operation unit 122b is recognized, and processing corresponding to this is performed. It has become. Note that the control unit 121 may further cause various controls and processes such as call control as a mobile phone and information processing as an information processing terminal.

  Specifically, the storage unit 123 stores, for example, a contact determination program, a pointer display program, and a gesture process execution program.

  The contact determination program determines how a user's finger or the like has touched the touch panel 112, and includes, for example, the following routine.

  The contact position recognition routine is for recognizing all position coordinates (x, y) in contact on the touch panel. In the following description, it is assumed that the upper left of the touch panel 112 in FIG. 1 is the origin, the right direction is the positive direction of the X axis, and the lower direction is the positive direction of the Y axis.

  The end contact determination routine is for storing the coordinates of the range of the end region 112b defined in advance and determining whether or not there is contact with the end region 112b.

  The multi-point contact determination routine is for identifying a contact point that is adjacent to the top, bottom, left, right, or within a certain distance as one contact surface, and identifies how many such contact surfaces are present.

  The gesture recognition routine is for determining that the gesture operation is performed when the operation after the contact of the user's finger or the like is an operation according to a predetermined rule.

  The processing content of the farthest contact position specifying routine from the end point will be described in detail later.

  The pointer display program is for displaying a pointer on the display unit 122a.

  The gesture process execution program is for executing a process according to the recognized gesture operation.

  Here, terms used below will be described. For example, the touch panel 112 is provided with electrodes in units of squares (coordinate points) shown in FIG. 3 and the like, and can detect a contact pressure of a finger or the like. For example, if the region P in FIG. 3A is pressed by a finger or the like and the pressure distribution at each coordinate point is as shown in FIG. 3B, the pressure is below a certain level in order to avoid the influence of noise. If the contact due to is ignored, a set of coordinate points exceeding a certain pressure indicated by a thick arrow in FIG. 3B can be recognized as one touch. Here, the number of coordinate points exceeding a certain pressure is defined as the contact area. Further, as shown in FIG. 3C, the center of gravity of the pressure at such a coordinate point is set as the center of gravity G of the contact. As shown in FIGS. 3D and 3E, a touch separated by a certain distance (for example, one or more coordinate points) is regarded as another touch and recognized as a plurality of touches. Further, when such a plurality of touches is accompanied by a predetermined rule of movement, it is recognized that a multi-touch gesture operation has been performed.

  Hereinafter, a specific example of processing performed by the control unit 121 will be described with reference to FIG.

  (S101) When one or more touches on the touch panel 112 are newly detected, the following series of processes is started.

  (S102) First, the new touch includes the coordinate point (end coordinate point) of the end region 112b (for example, the region outside the broken rectangle shown in FIG. 5) of the touch panel 112, or the main region 112a. It is determined whether only the coordinate points within are included. In this way, by determining whether any of the coordinate points is included in the end region 112b instead of the center of gravity of the touch region, it is possible to appropriately determine a touch that is likely to be an erroneous operation even when the touch region is wide. Easy to do.

  (S103) Whether a plurality of touches have been made including a later-described hold touch (a touch whose touch has been detected but whose operation has been recognized), that is, the new touch is a plurality of simultaneous touches or after a hold touch It is determined whether the touch is one or more touches, or whether there is one new touch and no pending touch.

  (S104) If there is only one new touch and there is no pending touch, then a pre-defined so-called flick operation has been performed, that is, for example, as shown in FIG. It is determined whether an operation of moving at a predetermined speed or more set in advance has been performed, or whether the touch P remains stationary as shown in FIG. Here, the gesture operation such as the flick operation is performed based on the center of gravity of the contact, for example.

  (S105) If it is determined that a flick operation has been performed, the flick operation is accepted and a process associated in advance is performed. That is, even a touch including an end coordinate point is treated as a valid touch that is determined as a flick operation, and a process corresponding to the operation is performed.

  (S106) On the other hand, if it is determined that the flick operation is not performed and the touch P remains stationary, only one touch including such an end coordinate point is an erroneous operation and a subsequent operation such as multiple touches. Since there is any possibility of introduction, recognition of the operation indicated by the touch is deferred, and recognition is performed in combination with a subsequent touch. However, the hold is canceled when the touch is finished when the process for the next operation is performed.

  (S107) If it is determined in the above (S103) that there are a plurality of touches such as the touches P1 and P2 shown in FIG. 7, for example, whether or not a predefined multi-touch gesture operation has been performed, for example, As shown in FIG. 8, it is determined whether or not an operation such as the touches P1 and P2 moving in the direction of the white arrow (reduction gesture, zoom-down operation) has been performed.

  (S108) If it is determined that a multi-touch gesture operation has been performed, the multi-touch gesture operation is accepted and processing associated in advance is performed. That is, as described for the flick operation, a touch that is determined to be a multi-touch gesture operation is treated as valid even for a touch including an end coordinate point, and processing corresponding to the operation is performed. Done.

  (S109) If it is determined in the above (S103) and (S107) that it is a multi-touch but not a multi-touch gesture operation, the edge determined to be included in the new touch in (S102) The coordinate point of another touch having the maximum distance from the coordinate point is obtained. That is, for example, when a touch including an end coordinate point is made near the base of the thumb, the operation of the coordinate point farthest from the end coordinate point is likely to be intended. In many cases, it is considered effective to examine the coordinate point having the maximum distance from the end coordinate point. Specifically, for example, in the case of the example of FIG. 9, the following processing is performed and a processing result is obtained.

  1. In the touch including the end coordinate point, the end contact determination routine determines which of the four sides of the touch panel 112 is the top, bottom, left and right (X coordinate is minimum, maximum, Y coordinate is minimum, maximum). It is determined whether it belongs to “side”. For example, in the example of FIG. 9, the touch PA includes an end coordinate point PA <b> 1 that belongs to the side with the maximum X coordinate.

  2. If the X coordinate of the end coordinate point is maximum or minimum, the coordinate point of another touch that has the maximum distance in the X-axis direction is searched. If the Y coordinate of the end coordinate point is maximum or minimum, the coordinate point of another touch that maximizes the distance in the Y-axis direction is searched. In the example of FIG. 9, the coordinate point having the minimum X coordinate is searched, and the coordinate points PB1 and PB2 in the touch PB correspond to this. The touch PC is ignored at any coordinate point because the distance in the X-axis direction is smaller than the coordinate points PB1 and PB2.

  3. Next, the above 2. In the direction of the coordinate axis that is orthogonal, the combination of coordinate points that maximizes the distance from any end coordinate point of the touch PA is searched. In the example of FIG. 9, PA1 and PB1 having the maximum distance in the Y-axis direction are obtained from the four combinations of coordinate points PA1 and PB1, PA1 and PB2, PA2 and PB1, and PA2 and PB2. Note that there are various specific ways of obtaining, for example, not necessarily comparing all the distances of the four combinations as described above. For example, the Y coordinate of the end coordinate points PA1 and PA2 of the touch PA is the maximum. The coordinate point PA1 of the touch and the coordinate point PB1 with the smallest Y coordinate among the coordinate points BP1 and BP2 of the touch PB, and the touch with the coordinate point PA2 with the smallest Y coordinate among the end coordinate points PA1 and PA2 of the touch PA The distances may be compared for only two pairs of the coordinate points PB2 with the maximum Y coordinate among the coordinate points BP1 and BP2 of the PB.

  4). When the touch includes end coordinate points of two or more sides, the same search is performed for each side, and the one having the maximum distance is obtained from the obtained set of coordinate points. Further, when there are a plurality of touches including the end coordinate points, the same search is performed for each, and the one with the maximum distance is obtained from the obtained set of coordinate points.

  The maximum distance is obtained by a routine for specifying the farthest contact position from the end point. For example, the sum of squares of distances in the X and Y axis directions between two coordinate points, or a square root thereof ((8 ^ 2 +11 in the example of FIG. 9). ^ 2) ^ (1/2) = 13.6: "^" represents a power)) may be determined based on whether it is larger than a predetermined threshold, or the distance in the X and Y axis directions (FIG. 9). In this example, X = 8, Y = 11) may be determined based on whether or not each is greater than a predetermined threshold, and at least one of the distances in the X and Y axis directions is greater than a predetermined threshold. It may be done by some means.

  In the case of the example of FIG. 10, the following processing result is obtained.

  1. It is determined that the touch PA includes end coordinate points PA1 to PA3 whose X coordinate belongs to the maximum side.

  2. A coordinate point with the minimum X coordinate is searched, and coordinate points PB1 and PB2 in the touch PB are obtained. The touch PC is ignored at any coordinate point because the distance in the X-axis direction is smaller than the coordinate points PB1 and PB2.

  3. Next, coordinate points PA3 and PB1, which have the maximum distance in the Y-axis direction among the coordinate points PB1 and PB2 of the touch PB and the coordinate points PB1 and PB2 of the touch PB, the distance D1, and the like are obtained.

  Further, in the case of the example of FIG. 11, the following processing result is obtained.

  1. It is determined that the touch PA includes the end coordinate points PA1 and PA2 whose Y coordinate belongs to the side on the maximum side.

  2. A coordinate point that minimizes the Y coordinate is searched, and coordinate points PB1 to PB3 in the touch PB are obtained. The touch PC is ignored at any coordinate point because the distance in the Y-axis direction is smaller than the coordinate points PB1 to PB3.

  3. Next, the coordinate points PA2 and PB3 having the maximum distance in the X-axis direction among the end coordinate points PA1 and PA2 of the touch PA and the coordinate points PB1 and PB2 of the touch PB, the distance D2, and the like are obtained.

  4). Furthermore, since the touch PB includes end coordinate points PB3 to PB5 whose X coordinate belongs to the side on the minimum side, the same processing is performed, and the one with the maximum distance is obtained. However, in this example, the search results are the same coordinate points PA2 and PB3, distance D2, and the like. In addition, when the same result is obtained in this way, one calculation may be omitted.

  Further, in the case of the example of FIG. 12, the following processing result is obtained.

  1. It is determined that the touch PA includes end coordinate points PA1 to PA4 whose X or Y coordinates belong to the side on the maximum side.

  2. A coordinate point that minimizes the X coordinate is searched, and coordinate points PB2 and PB3 in the touch PB are obtained. Further, the coordinate point with the minimum Y coordinate is searched, and the coordinate points PB1 and PB2 in the touch PB are obtained.

  3. Next, the coordinate points PA2 and PB2, the distance D3, and the like having the maximum distance in the Y-axis direction among the coordinate points PA1 and PA2 of the touch PA and the coordinate points PB2 and PB3 of the touch PB are obtained. Further, the coordinate points PA2 and PB2 having the maximum distance in the X-axis direction among the end coordinate points PA2 to PA4 of the touch PA and the coordinate points PB1 and PB2 of the touch PB, the distance D3, and the like are obtained. That is, in this example, the search results are obtained for the same coordinate points PA2 and PB2, distance D3, and the like. In the above case, the coordinate point PB2 may be obtained as the coordinate point having the maximum distance from the corner end coordinate point PA2.

  (S110) Next, it is determined whether or not the maximum distance obtained in (S109) is equal to or greater than a predetermined threshold.

  (S111) When the maximum distance is not greater than or equal to a predetermined threshold, that is, when a plurality of touches including end coordinate points have been performed, but it is determined that the touch area remains stationary without performing a multi-touch gesture operation, such as If the distance between the touches is not greater than or equal to a predetermined threshold, such operations are, for example, a touch P1 by the base of the thumb and a touch P2 by the belly of the thumb as shown in FIG. The operation may be a touch that is subsequently made with the tip of the thumb, an introduction to an operation such as the next multiple touch, or a simple erroneous operation. Therefore, the recognition of the operation indicated by the touch is suspended, and a determination is made as to where the user really wants to touch, in combination with the subsequent touch.

  (S112) If the maximum distance is equal to or greater than a predetermined threshold, it is determined whether the two coordinate points that are the maximum distance are both end coordinate points or one is a coordinate point in the main area 112a. (At least one coordinate point is always an end coordinate point since it is determined as YES in (S102) above).

  (S113) When one coordinate point is a coordinate point in the main area 112a, for example, as shown in FIG. 14, the touch P1 including the end coordinate point is a touch not intended by the user, and the main area There is a high possibility that the touch P2 including the coordinate point in 112a is a touch intended to operate the button region R, for example. Therefore, the touch P1 is ignored as an erroneous contact, the touch P2 is treated as valid, and processing according to the operation (including determination processing such as flick determination, long press and short press according to the subsequent operation). ) Is performed.

  (S114) On the other hand, when the two coordinate points that are the maximum distance are both end coordinate points, for example, as shown in FIG. 15, the touch P2 operated with the tip of the thumb uses the end coordinate points. Although it is included, there is a possibility that the operation is intended by the user. In such a case, since the operation of the touch P2 is usually performed after the touch P1 occurs, the touch P1 operated earlier in time is ignored as an erroneous contact, and the touch operated later. P2 is treated as valid, and processing corresponding to the operation is performed. Normally, in the state shown in FIG. 15 and the like, the possibility that the touches P1 and P2 are made simultaneously is low, but as an exceptional process, if the touches P1 and P2 are made simultaneously, (S111) ), Such a touch may be put on hold, and further determination may be performed according to the subsequent operation.

  (115) On the other hand, if it is determined in (S102) that the coordinate points included in the new touch are only the coordinate points in the main area 112a of the touch panel 112 as shown in FIG. In addition, it is determined whether or not the touch includes a plurality of touches including a hold touch and a multi-touch gesture operation is performed.

  (S116) When there is no pending touch and there is only one new touch, and when it is determined that the touch operation is not a multi-touch gesture even for a plurality of touches, only the coordinate point in the main area 112a is selected. Only the new touch including it is treated as an effective operation, processing corresponding to the operation is performed, and even if there is a hold touch, the hold touch is discarded.

  (117) When it is determined that a multi-touch gesture operation has been performed, the multi-touch gesture operation, that is, touches P1 and P2, for example, as shown in FIG. (Up operation) or the like is accepted, and processing associated in advance is performed. At this time, the touch Q not related to the gesture operation is ignored.

  As described above, when the edge area on the periphery of the touch panel is touched, the determination of the input operation based on the touch area is suspended, and the input operation can be determined based on the new touch area later, For example, it is possible to more appropriately determine whether the touch of the end region is an erroneous operation in which the base of the finger or the belly is unintentionally touched or the introduction to the next operation such as multiple touches. When the end region is touched, it is possible to more accurately determine effective operation and erroneous detection.

  As described above, the present invention is useful for an input device using a touch panel, and a mobile terminal device such as a mobile phone including such an input device.
