  2. Description of the Related Art In recent years, input devices such as a touch panel and a touch pad that enable user operations by contact or proximity have become widespread. For example, the touch panel includes a resistance film method, an infrared method, a capacitance method, and the like. Among these, the projection-type capacitive touch panel generally enables user operations at multiple points, and thus is used in various devices such as smartphones and tablet terminals.

  In the capacitive touch panel, the capacitance at the corresponding position changes according to the contact state or proximity state of the user's finger, and the capacitance value or the amount of change and the comparison result with a predetermined threshold value. Thus, the presence / absence of a user operation is determined. Therefore, there is also a technique for determining the presence or absence of a user operation with higher accuracy from the capacitance value or the amount of change.

  For example, in Patent Document 1, whether or not there is an erroneous input due to the deflection of the electrode of the capacitive sensor while determining the presence or absence of a user operation according to the comparison result between the measurement result of the capacitance value and a predetermined threshold value. A technique for determining and invalidating erroneous input due to deflection is disclosed.

It is determined. That is, depending on the position of a user operation such as contact or proximity, the accuracy of determining whether or not there is a user operation deteriorates.

An input device is provided that includes a determination unit that determines whether or not there is a user operation from a combination of two or more of the detection values if any of the detection values satisfies a first threshold condition. The The combination includes at least one detection value that satisfies the first threshold condition.

  According to the present disclosure, the acquisition unit that acquires the detection value of the sensor at each of the plurality of positions, and if none of the detection values satisfy the first threshold condition, it is determined that there is no user operation.

1. 1. Introduction Configuration of information processing apparatus 3. Process flow 4. Modification of combination determination 5. Hardware configuration Summary

<1. Introduction>
First, with reference to FIGS. 1 to 4, the appearance of the information processing apparatus according to the present embodiment, the determination of the presence / absence of a user operation by a conventional method, and problems in the conventional method will be described.

(Appearance of information processing device)
With reference to FIG. 1, an example of the external appearance of the information processing apparatus 100 according to the present embodiment will be described. FIG. 1 is an external view showing an example of the external appearance of the information processing apparatus 100 according to the present embodiment. Referring to FIG. 1, the information processing apparatus 100 includes a touch panel 310. User device 100 is, for example, a smartphone. As an example, here, the touch panel 310 is a capacitive touch panel.

  The information processing apparatus 100 acquires, for example, the contact position of the finger 10 on the touch panel 310 as input information in response to a user operation caused by the contact of the user's finger 10. More specifically, the touch panel 310 includes a capacitive sensor, and the sensor includes, for example, a plurality of electrodes arranged in parallel in the X-axis direction and a plurality of electrodes arranged in parallel in the Y-axis direction. Electrode. And the said sensor outputs the electrostatic capacitance value in the position of the intersection of the said electrode, or its variation | change_quantity, for example. That is, the sensor outputs a capacitance value on the XY plane or a distribution of detection results of the change amount thereof. Here, if there is a user operation by contact of the user's finger 10, the capacitance value or the distribution of the change amount thereof changes. Therefore, the presence / absence of a user operation is determined from the capacitance value or the distribution of the change amount, and the contact position is specified. In the following description, it is assumed that the change amount of the capacitance value is output as the detection value of the sensor.

  Further, the information processing apparatus 100 displays an image to be presented to the user on a display device included in the touch panel 310. For example, the display device included in the touch panel 310 displays objects 20 for user operations such as icons, buttons, and scroll bars.

(Determination of presence / absence of user operation by conventional method)
Next, with reference to FIG. 2, the determination of the presence / absence of a user operation according to the conventional method will be described.

  FIG. 2 is an explanatory diagram for explaining an example of the detection result of the change amount of the capacitance value. Referring to FIG. 2, the distribution of the amount of change in capacitance value detected by a sensor having 10 electrodes in the X-axis direction and 8 electrodes in the Y-axis direction is shown. This distribution is a distribution when one finger 10 is in contact with the vicinity of the intersection of the seventh electrode in the X-axis direction and the fifth electrode in the Y-axis direction (that is, in the case of single touch). For example, in this way, generally, the amount of change in the capacitance value at a position closer to the contact position becomes larger, and the amount of change in the capacitance value at a position farther from the contact position becomes smaller. Then, the peak change amount 11 appears at the position closest to the contact position, that is, at the intersection of the seventh electrode in the X-axis direction and the fifth electrode in the Y-axis direction. Here, the “peak change amount” is a change amount larger than the change amount at any position adjacent to the position of the peak change amount. That is, the peak change amount 11 is a maximum value in the distribution of the change amount of the capacitance value.

  Further, the detected change amount of the capacitance value changes according to the contact strength of the user finger 10, that is, the area where the user's finger 10 contacts the touch panel 310, for example. For example, when the user's finger 10 is strongly touched on the touch panel 310 and thereby the contact area of the finger 10 with the touch panel 310 is increased, the detected change amount becomes larger.

  In the conventional method, the presence / absence of a user operation is determined based on the result of comparison between the detected change amount of the capacitance value and a predetermined threshold value. More specifically, for example, as a result of comparing the peak change amount 11 of FIG. 2 with a predetermined threshold, if the peak change amount 11 is equal to or greater than the predetermined threshold, it is determined that there is a user operation, and the peak change amount If 11 is less than the predetermined threshold, it is determined that there is no user operation.

(Problems with conventional methods)
Next, problems in the conventional method will be described with reference to FIGS.

  FIG. 3 is an explanatory diagram for explaining an example of a change in the peak change amount. Referring to FIG. 3, dragging in the X-axis direction by the user's finger 10 is performed as in 3a. Here, it is assumed that the contact strength of the finger 10 to the touch panel 310 is constant throughout the drag. During the drag, the peak change amount 11 changes as shown in 3b. That is, even if the contact strength of the finger 10 is the same, the peak change amount 11 changes depending on the contact position of the user's finger 10, that is, the position of the user operation.

  In the capacitive touch panel 310, the peak change amount becomes larger when the user's finger 10 is closer to the sensor electrode, and the peak change amount becomes smaller when the user's finger 10 is farther from the electrode. Therefore, a phenomenon such as 3b in FIG. 3 occurs. This point will be described in more detail with reference to FIG.

  FIG. 4 is an explanatory diagram for explaining an example of the distribution of the change amount of the capacitance value according to the position of the user operation. Referring to FIG. 4, when the user's finger 10 comes in contact with the fifth electrode in the X-axis direction, the change amount of the capacitance value is detected as in 4a. In this case, the peak change amount 11a is about 70. On the other hand, when the user's finger 10 has the same contact strength as in the case of 4-1, the amount of change in the capacitance value as in 4b when the user's finger 10 is in contact between the fifth electrode and the sixth electrode in the X-axis direction. Is detected. In this case, the peak change amount 11b is about 55.

  As a result, even if the contact strength of the user's finger 10 is the same, the determination result of the presence / absence of the user operation may vary depending on the position of the user's finger 10 contact, that is, the position of the user operation. For example, as illustrated in FIG. 4, it is assumed that the threshold value Ctt for determining the presence / absence of a user operation is set to 58. In this case, in the case of 4-1, since the peak change amount 11 is equal to or greater than the threshold value Ctt, it is determined that there is a user operation. On the other hand, in the case of 4-2, since the peak change amount 11 is less than the threshold value Ctt, it is determined that there is no user operation. That is, user operations between the electrodes of the sensor are not easily recognized.

  As described above, in the conventional method, the accuracy of the determination of the presence / absence of the user's operation is deteriorated depending on the position of the user's operation due to the arrangement of the sensors. Therefore, in the present embodiment, it is possible to more accurately determine the presence / absence of a user operation regardless of the position of the user operation. Thereafter, <2. Configuration of information processing apparatus>, <3. The specific contents of the processing flow> and <4. Modification of Combination Determination> will be described.

<2. Configuration of information processing apparatus>
An example of the configuration of the information processing apparatus 100 according to the present embodiment will be described with reference to FIGS. FIG. 5 is a block diagram illustrating an example of the configuration of the information processing apparatus 100 according to the present embodiment. Referring to FIG. 5, the information processing apparatus 100 includes a sensor 110, an acquisition unit 120, a determination unit 130, a storage unit 140, a control unit 150, and a display unit 160.

(Sensor 110)
The sensor 110 detects a value at each of a plurality of positions. More specifically, for example, the sensor 110 detects the amount of change in capacitance value at each of a plurality of positions on the touch panel 310. The plurality of positions are, for example, positions of intersections of electrodes included in the sensor 110. It can be said that the change amount of the capacitance value at the plurality of positions is a distribution of the change amount of the capacitance value. The sensor 110 outputs the change distribution of the capacitance value to the acquisition unit 120. In the present embodiment, since the value detected by the sensor 110 is described as a change amount of the capacitance value, the change amount of the capacitance value is also referred to as the detection value of the sensor 110 in the following. Can do.

(Acquisition part 120)
The acquisition unit 120 acquires the amount of change in capacitance value at each of a plurality of positions. More specifically, for example, the acquisition unit 120 acquires, from the sensor 110, the change amount of the capacitance value at each of a plurality of positions on the touch panel 310, that is, the distribution of the change amount of the capacitance value. When the change amount of the capacitance value from the sensor 110 is an analog value, the acquisition unit 120 acquires the change amount of the digital capacitance value by analog / digital conversion. The acquisition unit 120 outputs the acquired distribution of changes in capacitance value to the determination unit 130.

(Determination unit 130)
The determination unit 130 determines that there is no user operation if none of the amount of change in the capacitance value satisfies the first threshold condition. More specifically, if any change amount of the capacitance value is less than the threshold value CT1, the determination unit 130 determines that there is no user operation. That is, the first threshold value condition in this case is a change amount of capacitance value ≧ CT1. On the other hand, the determination unit 130 determines the presence / absence of a user operation from a combination of two or more capacitance value change amounts if any one of the capacitance value change amounts satisfies the first threshold value condition. That is, more specifically, if the threshold value CT1 or more, the determination unit 130 determines whether or not there is a user operation from a combination of two or more capacitance value change amounts (hereinafter referred to as “combination determination”). )I do. The combination of the two or more capacitance change amounts includes at least one capacitance value change amount that satisfies the first threshold condition, that is, a capacitance value change amount equal to or greater than CT1. The threshold value CT1 here is, for example, a value corresponding to 70% of a threshold value (threshold value CT2 to be described later) of a method for performing determination using an individual change amount as in the prior art.

  Rather than the determination by comparing the amount of change in the individual capacitance value and the threshold as in the conventional case, the presence or absence of the user operation is more determined by the first threshold condition and the combination determination, regardless of the position of the user operation. It becomes possible to determine with high accuracy. More specifically, in a case where the amount of change is low despite a user operation, such as a case where the user's finger 10 is positioned between the electrodes, for example, the amount of change of a certain amount is a plurality of positions. Appears dispersed. However, if the user operation determination threshold is lowered in order to determine that there is a user operation only from the individual change amount, the possibility that it is determined that there is a user operation despite no user operation increases. That is, there is a concern that the accuracy of determination may be reduced due to erroneous recognition. Therefore, in consideration of the fact that a certain amount of change appears when there is a user operation, first the user's operation is performed by checking whether the individual change amount satisfies the first threshold condition. Nevertheless, identify cases where the amount of change may be low. Then, in consideration of the fact that the change amount appears dispersedly in a plurality of positions when there is a user operation but the individual change amount is low, the next change amount satisfies the first threshold condition instead of the individual change amount. It is determined whether or not a user operation has really been performed using a combination of two or more change amounts including. By using the first threshold condition and the combination determination, the user operation can be performed without increasing the possibility of misrecognition even when the individual change amount is lowered depending on the position of the user operation. It becomes possible to recognize with certainty.

  Further, the above combination determination can be suitably combined with the conventional method determination. For example, the determination unit 130 determines that there is a user operation when the change amount of the capacitance value satisfies the second threshold value condition. More specifically, for example, if any change amount included in the distribution of the change amount of the capacitance value from the acquisition unit 120 is greater than or equal to the threshold value CT2, the determination unit 130 sets the user at the position of the change amount. It is determined that there is an operation (for example, contact with the user's finger 10). That is, the second threshold value condition in this case is a change amount of capacitance value ≧ CT2. As an example, the threshold value CT2 corresponds to 80% of the Cf, where Cf is the amount of change in the capacitance value detected when the minimum finger allowed for user operation is located immediately above the electrode of the sensor 110. Value. Further, as described above, the threshold value CT1 is a value corresponding to 70% of the threshold value CT2 as an example.

  On the other hand, the determination unit 130 performs the combination determination when none of the change amounts of the capacitance values satisfy the second threshold condition. More specifically, for example, when the change amount included in the distribution of the change amount of the capacitance value from the acquisition unit 120 is less than the threshold value CT2, the determination unit 130 determines two or more change amounts. The presence / absence of a user operation is determined from the combination.

  Thus, by combining the conventional method and the combination determination, when there is clearly a user operation, it is easily determined that there is a user operation, and when there is a suspicion of whether there is a user operation, the user operation It becomes possible to determine more precisely whether or not there is.

  Hereinafter, the combination determination will be described in more detail.

  In the combination determination, the combination of the change amounts of the two or more capacitance values includes, for example, the change amounts of the capacitance values at two or more consecutive positions among the plurality of positions. A continuous position here means that each position is adjacent to at least one other position. As described above, by using the combination of the amount of change in the capacitance value at successive positions, it is possible to determine using the amount of change related to the same user operation (for example, contact with a user's finger). . In addition, it is possible to avoid erroneously recognizing a user operation due to a combination of unrelated change amounts. Note that the amount of change in capacitance value at successive positions includes, for example, a value greater than or equal to the threshold value CT1. The combination may include a change amount at one or more discrete positions in addition to a change amount at two or more consecutive positions.

  The combination of the two or more capacitance value changes includes a peak change amount 11 and a change amount at at least one position adjacent to the position of the peak change amount 11. Here, the peak change amount 11 is a change amount having a larger difference from the change amount when there is no user operation (for example, 0) than the change amount at any position adjacent to the position of the peak change amount 11. is there. <1. As already described in Introduction>, when the user's finger 10 is touched, the peak change amount 11 usually appears at a position closest to the contact position. Therefore, if there is a user operation, it can be considered that this is near the peak change amount 11. Therefore, the determination using the peak change amount 11 is effective in determining the presence / absence of a user operation. Further, by narrowing down the determination target to the combination including the peak change amount 11, it is possible to avoid an increase in the calculation amount due to the determination using the combination of the change amount of the capacitance value irrelevant to the user operation. Note that the peak change amount 11 included in the combination of the two or more capacitance value change amounts is, for example, the peak change amount 11 greater than or equal to the threshold value CT1. Further, in the combination of the two or more capacitance value change amounts, the capacitance value change amount at the consecutive positions includes, for example, a peak change amount 11 equal to or greater than the threshold CT1.

  Here, a specific combination determination method in the present embodiment will be described. The determination unit 130 calculates a virtual peak value (hereinafter referred to as “virtual peak value”) from a combination of two or more capacitance value changes as the combination determination, and the virtual peak value is the second value. If the threshold condition is satisfied, it is determined that there is a user operation. <1. As described with reference to FIG. 4 in the introduction>, when there is contact between the electrodes of the sensor 110, the amount of change in the capacitance value is smaller than when there is contact on the electrodes. Therefore, even when the contact is between the electrodes, if the amount of change in the capacitance value estimated to be detected if the contact is on the electrode is calculated as a virtual peak value and used, Even when there is between the electrodes, it is possible to maintain the accuracy of the determination of whether or not there is a user operation.

  More specifically, the combination of the two or more capacitance value changes is, for example, a peak change amount 11 and a change amount at a position adjacent to the position of the peak change amount 11 is determined by the user operation. A change amount (hereinafter, referred to as “quasi-peak change amount”) having a larger difference from the change amount when there is no change (for example, 0). The virtual peak value is a change amount of the capacitance value estimated for a virtual position between the position of the peak change amount and the position of the quasi-peak change amount. When the user's finger 10 is in contact between the electrodes of the sensor, usually a large amount of change is detected in the electrode near the contact position. For example, if the user's finger 10 is in contact between the 5th electrode and the 6th electrode in the X-axis direction as shown in FIG. 4B, the amount of change is large at the positions of the 5th electrode and the 6th electrode. Is detected. In this case, the peak change amount 11b is detected at the position of the fifth electrode, and the quasi-peak change amount is detected at the sixth electrode. Thus, if the user operation is between the electrodes, it can be considered that the user operation is between the position of the peak change amount 11 and the position of the quasi-peak change amount. Therefore, if an electrode is present between the peak change amount position and the quasi-peak change amount position, the virtual peak value is estimated to be detected at a position (virtual position) on the electrode. It can be said that the amount of change in capacitance value. Thus, the capacitance detected when the user operation is on the electrode by estimating the amount of change in the capacitance value at the virtual position using the peak change amount 11 and the quasi-peak change amount. A virtual peak value closer to the amount of change in value can be obtained.

  More specifically, the determination unit 130 determines the peak change amount 11, the quasi-peak change amount, and the change in the capacitance value estimated in the direction from the position of the peak change amount 11 to the quasi-peak change amount. A virtual peak value is calculated from the amount increase degree I1 and the increase amount I2 of the capacitance value change amount estimated in the direction from the position of the quasi-peak change amount to the position of the peak change amount. In the graph of the change amount of the capacitance value with respect to the position as shown in FIG. 4, the increase degrees I1 and I2 are set as the slope of a straight line representing the increase or decrease of the change amount of the capacitance value with respect to the position. Can be caught. Hereinafter, a calculation example of the virtual peak value will be described in more detail with reference to FIGS. 6 and 7.

  FIG. 6 is an explanatory diagram for describing a first example of calculation of the virtual peak value Cvx. Referring to FIG. 6, a peak change amount 11 (peak change amount Cp) that is less than the threshold value CT2 and greater than or equal to the threshold value CT1 and a quasi-peak change amount 13 are shown. Further, it is a change amount of the capacitance value at a position adjacent to the position of the peak change amount 11 (electrode number 5), and is a position opposite to the position (electrode number 4) of the quasi-peak change amount 13 (electrode number 6). The change amount 15 of the electrostatic capacitance value in FIG. Further, a change amount 17 at a position adjacent to the position (electrode number 4) of the quasi-peak change amount 13 and a change amount 17 at a position (electrode number 3) opposite to the position of the peak change amount 11 (electrode number 5). It is shown.

  In this example, the determination unit 130 determines the position of the quasi-peak change amount 13 (electrode) from the position of the peak change amount 11 (electrode number 5) based on the difference between the change amount 15 of the capacitance value and the peak change amount 11. The degree of increase I1 to number 4) is estimated. That is, the determination unit 130 changes the capacitance value from the position of the electrode number 5 toward the position of the electrode number 4 with the slope of the straight line 21 passing through the change amount 15 of the capacitance value and the peak change amount 11. Estimate that the amount increases. In this example, the determination unit 130 determines the position of the peak change amount 11 from the position of the quasi-peak change amount 13 (electrode number 4) based on the difference between the change amount 15 of the capacitance value and the peak change amount 11. The degree of increase I2 to (electrode number 5) is also estimated. That is, the determination unit 130 estimates that the amount of change in the capacitance value increases from the position of the electrode number 4 toward the position of the electrode number 5 with the inclination of the straight line 23 that is symmetric with the straight line 21. Then, the amount of change 30a at the intersection of the straight line 21 and the straight line 23 is calculated as the virtual peak value Cvx.

  Note that the determination unit 130 may specify the virtual position 40a as the position of the user operation from the calculation result of the virtual peak value Cvx. Thus, if the position is specified, a position closer to the actual position of the user operation can be obtained as an input.

  FIG. 7 is an explanatory diagram for describing a second example of calculation of the virtual peak value Cvx. Referring to FIG. 7, similarly to FIG. 6, a peak value 11, a quasi-imaginary peak value 13, a capacitance value change amount 15, and a capacitance value change amount 17 are shown. A straight line 21 is also shown in the same manner as in FIG.

  In this example, the increase degree I1 is the same as that in the example of FIG. On the other hand, the increase degree I2 is different from the example of FIG. In this example, the determination unit 130 determines the position of the peak change amount 11 from the position of the quasi-peak change amount 13 (electrode number 4) based on the difference between the change amount 17 of the capacitance value and the quasi-peak change amount 13. The degree of increase I2 to (electrode number 5) is estimated. That is, the determination unit 130 determines the capacitance value from the position of the electrode number 4 toward the position of the electrode number 5 by the slope of the straight line 25 that passes through the change amount 17 of the capacitance value and the quasi-peak change amount 13. It is estimated that the amount of change will increase. Then, the amount of change 30b at the intersection of the straight line 21 and the straight line 25 is calculated as the virtual peak value Cvx.

  The combination determination has been described in detail above. In this description, an example in which the user operation is a single touch, that is, a user operation by touching one place has been given. However, this embodiment is not limited to this. For example, in the combination determination, the determination unit 130 individually determines the presence / absence of a user operation from each of a plurality of different combinations. As described above, the combination determination makes it possible to more accurately determine the presence or absence of individual contacts even when there is multi-touch. This point will be described in more detail with reference to FIG.

  FIG. 8 is an explanatory diagram for describing a first example of the detection result of the change amount of the capacitance value by multi-touch. Referring to FIG. 8, two peak change amounts 11a and 11b that are equal to or greater than the threshold value CT1 (less than the threshold value CT2) are shown. In this case, for example, the determination unit 130 performs the combination determination using a combination of the change amounts of the capacitance values including the peak change amount 11a, and uses another combination of the change amounts including the peak change amount 11b. Further combination determination is performed. In this way, for example, multitouch detection can be performed by selecting a change amount combination for each change amount greater than or equal to the threshold CT1 or a peak change amount 11 greater than or equal to the threshold CT1 and calculating the virtual peak value Cvx. .

  Furthermore, even when the amount of change in the capacitance value satisfies the second threshold condition, the determination unit 130 determines the presence / absence of a user operation from a combination of other amounts of change that do not satisfy the second threshold condition. This point will be described in more detail with reference to FIG.

  FIG. 9 is an explanatory diagram for explaining a second example of the detection result of the change amount of the capacitance value by multi-touch. Referring to FIG. 9, one peak change amount 11 that is less than the threshold value CT2 and greater than or equal to the threshold value CT1 and one peak change amount 18 that is greater than or equal to the threshold value CT2 are shown. In this case, the determination unit 130 determines that there is a user operation at the position of the electrode number 9 based on the peak change amount 18 and uses the combination of the capacitance value change amounts including the peak change amount 11 to determine the combination. I do. Thus, for example, even if there is a peak change amount 18 greater than or equal to the threshold CT2, a combination of change amounts of capacitance values is selected for each peak change amount 11 that is greater than or equal to the threshold CT1 and less than the threshold CT2, and the virtual peak value Cvx is determined. By calculating, multi-touch can be detected. Of course, when the determination based on the comparison between the threshold CT1 and the individual change amount is not performed, the combination determination may be performed using a combination of the change amount of the capacitance value including the peak change amount 18. .

  As described above, the determination unit 130 determines the presence / absence of a user operation and specifies the position of the user operation. If the determination unit 130 determines that there is a user operation, the determination unit 130 outputs the position of the user operation to the control unit 150.

(Storage unit 140)
The storage unit 140 stores information that should be temporarily or permanently stored in the information processing apparatus 100. For example, the storage unit 140 stores a threshold value CT1 and a threshold value CT2 used by the determination unit 130.

(Control unit 150)
The control unit 150 executes various processes in the information processing apparatus 100. For example, the control unit 150 executes processing according to the position of the user operation specified by the determination unit 130. In addition, the control unit 150 controls display of images on the display unit 160.

(Display unit 160)
The display unit 160 displays an image to be presented to the user. The display unit 160 displays, for example, the object 20 for user operation such as an icon, a button, or a scroll bar on the touch panel 310.

<3. Process flow>
Next, an example of input processing according to the present embodiment will be described with reference to FIG. FIG. 10 is a flowchart illustrating an example of a schematic flow of input processing according to the present embodiment.

  First, in step S <b> 201, the acquisition unit 120 acquires the amount of change in capacitance value at each of a plurality of positions on the touch panel 310.

  Next, in step S <b> 203, the determination unit 130 checks whether or not the amount of change in capacitance value satisfies the second threshold condition. That is, the determination unit 130 checks whether or not the change amount of the capacitance value is greater than or equal to the threshold value CT2. As a result, if any change amount is equal to or greater than CT2, the determination unit 130 determines that there is a user operation at the position of the change amount, and the process proceeds to step S205. If any amount of change is less than CT2, the process proceeds to step S207.

  In step S <b> 205, the determination unit 130 identifies the position of the change amount that is equal to or greater than the threshold CT <b> 2 as the position of the user operation, and outputs the position of the user operation to the control unit 150.

  In step S207, the determination unit 130 checks whether any of the change amounts Cp less than the threshold CT2 satisfies the first threshold condition. That is, the determination unit 130 checks whether any of the change amounts less than the threshold value CT2 is greater than or equal to the threshold value CT1. As a result, if any amount of change is greater than or equal to CT1, the process proceeds to step S209. If any amount of change is less than CT1, the process returns to step S201.

  In step S209, the determination unit 130 calculates a virtual peak value Cvx. If any virtual peak value Cvx is greater than or equal to the threshold value CT2 in step S211, the determination unit 130 determines that there is a user operation, and the process proceeds to step S213. If any virtual peak value Cvx is less than CT2, the process returns to step S201.

  In step S213, the determination unit 130 identifies the virtual position 40a as the position of the user operation from the calculation result of the virtual peak value Cvx, and outputs the position of the user operation to the control unit 150. Then, the process returns to step S201.

<4. Modified example of combination determination>
Although the method of calculating the virtual peak value has been described as an example of the combination determination in the present embodiment, the combination determination method is not limited to this. Here, examples of three methods will be described as another method of combination determination. These combination determination methods can be used instead of or in combination with the method of calculating the virtual peak value.

(First modification)
First, as a combination determination, the determination unit 130 may determine that there is a user operation if each change amount of the capacitance value at a predetermined number of consecutive positions satisfies the third threshold condition. The third threshold condition here is the same as the first threshold condition, for example. That is, the third threshold condition is that the amount of change in capacitance value is equal to or greater than the threshold CT1. The predetermined number is, for example, 2 or 3. This combination determination will be described in more detail with reference to FIG.

  FIG. 11 is an explanatory diagram for explaining a first modification of the combination determination. Referring to FIG. 11, three capacitance value variations 19 that are equal to or greater than the threshold CT1 (less than the threshold CT2) are detected. The three change amounts 19 are change amounts at successive positions (positions of electrode numbers 3, 4, and 5). Therefore, when the change amount of the capacitance value as shown in FIG. 11 is detected, the determination unit 130 determines that there is a user operation. In general, when the contact area of the user operation is too large, a large amount of change appears at a plurality of positions as shown in FIG. 11, but any amount of change may be less than the threshold value CT2. In such a case, even if the virtual peak value is calculated, the virtual peak value can be less than the threshold value CT2. Therefore, according to the first modified example of the combination determination, it is possible to correctly determine that there is a user operation even when there is a user operation with such a large contact area.

(Second modification)
Second, the determination unit 130 may include two or more consecutive positions among the plurality of positions in a two-dimensional plane or a three-dimensional space indicating the relationship between the plurality of positions and the amount of change in capacitance value. The area or volume may be calculated based on the amount of change in capacitance value at the two or more consecutive positions. Then, the determination unit 130 may determine that there is a user operation if the area or volume satisfies the fourth threshold condition. This combination determination will be described in more detail with reference to FIG.

  FIG. 12 is an explanatory diagram for explaining a second modification of the combination determination. Referring to FIG. 12, a two-dimensional plane showing the relationship between a plurality of positions (positions of electrode numbers 1 to 10) and the amount of change in capacitance value is shown. Referring to FIG. 11, the determination unit 130 includes, for example, consecutive positions (electrode numbers 3 to 3) from the position of the minimum value 12 a to the position of the minimum value 12 b including the position of the peak change amount 11 (electrode number 5). In 8), the area of the portion 50 sandwiched between the line graph of the change amount of the capacitance value and the X axis is calculated. And the determination part 130 determines with there being user operation, when the said area is more than a threshold value. The area calculated in this way increases according to the contact strength of the user operation. Therefore, even if the peak operation amount 11 is less than the threshold value CT2 because the position of the user operation is between the electrodes, the presence or absence of the user operation can be correctly determined by determining the presence or absence of the user operation based on the area. Increases nature. Although the case where the area is used has been described here, the same effect can be obtained when the volume in the space as shown in FIG. 2 is used.

(Third Modification)
Third, as the combination determination, the determination unit 130 calculates a sum from the amount of change in the capacitance value at two or more consecutive positions of the plurality of positions, and the calculated sum is the fifth threshold value. If the condition is satisfied, it may be determined that there is a user operation. For example, the determination unit 130 calculates the sum total from the peak change amount 11 and the eight change amounts at eight positions adjacent to the position of the peak change amount 11. The sum may be a mere sum of these nine changes, or may be a weighted sum that is weighted by position. And the determination part 130 determines with there being user operation, when the calculated sum total is more than a threshold value. The sum calculated in this way also increases according to the contact strength of the user operation. Therefore, even if the peak operation amount 11 is less than the threshold value CT2 because the position of the user operation is between the electrodes, the presence / absence of the user operation can be correctly determined by determining the presence / absence of the user operation by the above sum. Increases nature.

  As described above, three modified examples have been described as the combination determination. However, the combination determination in the present embodiment is not limited to these, and various other combination determinations can be applied to the present embodiment.

<5. Hardware configuration>
Next, an example of the hardware configuration of the information processing apparatus 100 according to the present embodiment will be described with reference to FIG. FIG. 13 is a block diagram illustrating an example of a hardware configuration of the information processing apparatus 100 according to the present embodiment. Referring to FIG. 13, the information processing apparatus 100 includes a CPU (Central Processing Unit) 301, a ROM (Read Only Memory) 303, a RAM (Random Access Memory) 305, a bus 307, a storage device 309, and a touch panel 310.

  The CPU 301 functions as an arithmetic processing device and a control device, and controls the overall operation in the information processing device 100 or a part thereof in accordance with various programs recorded in the ROM 303 or the storage device 309. The ROM 303 stores programs and calculation parameters used by the CPU 301. The RAM 305 is used as a work memory for the CPU 301 to develop a program when the program is executed, and is used as a buffer memory for temporarily recording data.

  A bus 307 connects the CPU 301, the ROM 303, and the RAM 305 to each other. A storage device 309 and a touch panel 310 are further connected to the bus 307.

  The recording device 309 stores various data such as basic software such as an OS and applications. Here, the recording device 309 may be, for example, a magnetic recording medium such as a hard disk, such as an EEPROM (Electrically Erasable and Programmable Read Only Memory), a flash memory, a MRAM (Magnetoresistive Random Access Memory). ), FeRAM (Ferroelectric Random Access Memory), PRAM (Phase change Random Access Memory), and the like.

  The touch panel 310 includes a display device 311, a sensor 313, and a controller 315.

  The display device 311 displays an output image from the information processing device 100. The display device 311 may be, for example, an LCD, an organic EL display (organic ElectroLuminescence display), or the like.

  The sensor 313 detects a value corresponding to a user operation such as contact, proximity, or pressing on the touch panel 310. The sensor 313 may be, for example, a sensor using a capacitance method, a resistance film method, an optical method, or the like on the assumption that detection values at a plurality of positions can be output. The sensor 313 may be an in-cell type sensor.

  The controller 315 is a module of the touch panel 310 and controls the sensor 313. For example, the controller 315 sets a threshold value, a gain, and the like of the sensor 313. The controller 315 functions as an interface between the sensor 313 and the CPU 301.

  Note that the acquisition unit 120 and the determination unit 130 in this embodiment may be implemented by the CPU 301, the ROM 303, the RAM 305, and the storage device 309, or may be implemented by the controller 315. For example, the sensor 110 is mounted by the sensor 313, the storage unit 140 is mounted by the storage device 309, and the display unit 160 is mounted by the display device 311.

<6. Summary>
So far, the information processing apparatus 100 according to the embodiment of the present disclosure has been described with reference to FIGS. According to the present embodiment, by using the first threshold condition and the combination determination, it is possible to determine the presence / absence of the user operation with higher accuracy regardless of the position of the user operation. More specifically, in a case where the amount of change is low despite a user operation, such as a case where the user's finger 10 is positioned between the electrodes, for example, the amount of change of a certain amount is a plurality of positions. Appears dispersed. However, if the user operation determination threshold is lowered in order to determine that there is a user operation only from the individual change amount, the possibility that it is determined that there is a user operation despite no user operation increases. That is, there is a concern that the accuracy of determination may be reduced due to erroneous recognition. Therefore, in consideration of the fact that a certain amount of change appears when there is a user operation, first the user's operation is performed by checking whether the individual change amount satisfies the first threshold condition. Nevertheless, identify cases where the amount of change may be low. Then, in consideration of the fact that the change amount appears dispersedly in a plurality of positions when there is a user operation but the individual change amount is low, the next change amount satisfies the first threshold condition instead of the individual change amount. It is determined whether or not a user operation has really been performed using a combination of two or more change amounts including. By using the first threshold condition and the combination determination, the user operation can be performed without increasing the possibility of misrecognition even when the individual change amount is lowered depending on the position of the user operation. It becomes possible to recognize with certainty.

  Also, by fusing the determination of the conventional method with the second threshold condition, when there is clearly a user operation, it is easily determined that there is a user operation, and if there is a doubt about whether there is a user operation, It becomes possible to more strictly determine whether or not there is a user operation.

  Further, the combination determination based on the virtual peak value can maintain the accuracy of the determination as to whether or not there is a user operation even when the contact is between the electrodes. Further, by specifying the virtual position 40a as the position of the user operation from the calculation result of the virtual peak value Cvx, a position closer to the actual position of the user operation can be obtained as an input.

  Further, according to the combination determination of the first modification, it is possible to correctly determine that there is a user operation even when there is a user operation with a large contact area. Further, the combination determination of the second modification and the third modification increases the possibility of correctly determining the presence / absence of the user operation even when the position of the user operation is between the electrodes.

  In addition, by performing combination determination from each of a plurality of different combinations, it is possible to more accurately determine the presence or absence of individual multi-touch.

  In the example of the combination determination, the combination determination based on the virtual peak value is particularly effective. Referring to FIG. 14, as an example, when dragging in the X-axis direction by the user's finger 10 is performed as illustrated in 3 a of FIG. 3, the peak change amount 11, the virtual peak value 30, and It shows how the total amount of change in the capacitance value of Modification 3 changes. Here, the total amount of change in capacitance value is the sum of peak change amount 11 and eight change amounts at eight positions adjacent to the position of peak change amount 11. In FIG. 14, the change in the peak change amount 11, the change in the virtual peak value, and the change in the sum of the change amounts are shown as a curve 61, a curve 63, and a curve 65, respectively. The peak change amount changes drastically according to the change of the X coordinate as shown by the curve 61, and the total change amount of the capacitance value is more gradual than that of the curve 61, but is stable as shown by the curve 65. There is no change. On the other hand, even if the X coordinate changes, the virtual peak value maintains a stable value with almost no fluctuation like the curve 63. Thus, according to the virtual peak value, it is possible to accurately determine the presence / absence of a user operation regardless of the position of the user operation.

  As mentioned above, although preferred embodiment of this indication was described referring an accompanying drawing, it cannot be overemphasized that this indication is not limited to the example concerned. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present disclosure. Understood.

  For example, although an example in which the determination by comparison between the detection value of the individual sensor and the threshold value CT1 and the combination determination are used together has been described, of course, only the combination determination of these determinations may be used.

  Moreover, the sensor of a touch panel may enable user operation by proximity | contact, a press, etc. instead of user operation by contact. In this case, the detection value of the sensor changes according to, for example, the proximity distance, the magnitude of the pressure, and the like. In addition, the sensor of the touch panel may be a sensor of any method other than the capacitance method, such as a resistance film method or an optical method, as long as detection values at a plurality of positions can be output. The sensor of the touch panel may be an in-cell type sensor. In the above-described embodiment, an example is shown in which the sensor is a capacitance type sensor, and the detection value of the sensor is a change amount of the capacitance value. However, the detection value of the sensor is the capacitance value itself. Or another value obtained by performing some calculation on the capacitance value.

  Further, for the sake of simple explanation, examples of the distribution of detected values mainly focusing on the X-axis direction are shown in the respective drawings. Of course, the same applies to the distribution of detected values focusing on the Y-axis direction. A determination method can be applied. That is, instead of using the detection value distribution in the X-axis direction or in combination with the determination, the determination using the detection value distribution in the Y-axis direction may be performed. In this case, for example, when the threshold condition for the combination determination is satisfied in either the X-axis direction or the Y-axis direction (for example, the virtual peak value is greater than or equal to the threshold CT2 in either the X-axis direction or the Y-axis direction) It may be determined that there is a user operation. In addition, the same determination method (for example, determination based on a virtual peak value) is applied to the entire distribution of detected values on the XY plane as shown in FIG. 2 instead of a single axis, either the X axis or the Y axis. can do.

  Moreover, although the example in which the user's finger 10 is used as the user operation has been described, means (for example, a touch pen) other than the user's finger 10 may be used.

  Although an example in which the input device is a touch panel has been described, the input device may be another device (for example, a touch pad) as long as it can output detection values at a plurality of positions like a touch panel.

  Moreover, although the smart phone was mentioned as an example of information processing apparatus, the information processing apparatus may be provided with the input device or another device connected to the input device.

  Further, each step in the input processing of this specification does not necessarily have to be processed in time series in the order described in the flowchart. For example, each step in the input process may be processed in an order different from the order described as the flowchart, or may be processed in parallel.

  In addition, it is possible to create a computer program for causing hardware such as a CPU, ROM, and RAM incorporated in the information processing apparatus to exhibit functions equivalent to those of each configuration of the information processing apparatus. A storage medium storing the computer program is also provided.
