Description

  The present application belongs to the technical field of an operation device, an operation control method, an information processing device, and an operation device program. More specifically, for example, the present invention belongs to the technical field of an operation device including a contacted portion such as a touch panel, an operation control method in the operation device, an information processing device including the operation device, and a program for the operation device.

  In recent years, portable terminal devices such as so-called smartphones and tablet terminals have been widely used. In addition, so-called touch panels are also generalized as interfaces used when the user operates these terminal devices. In this touch panel, a touch operation on the touch panel using a user's finger or a touch pen is executed, and various operation commands corresponding to the content of the touch operation are output from the control unit of the touch panel. And the process corresponding to the said operation command is performed in the said terminal device. In the following description, the user's finger or touch pen is collectively referred to simply as “finger”.

  On the other hand, as an example of the above touch operation on the touch panel, “tap” that releases a finger or the like immediately after touching the touch panel (that is, the touch panel is operated so as to strike the touch panel) or “double tap” that performs tapping twice in a short time. Alternatively, a touch operation such as “slide” is performed in which a finger once brought into contact with the touch panel is moved while maintaining the contact and then released from the touch panel. As an example of a conventional technique related to an operation on such a touch panel, there is a technique described in Patent Document 1 below.

  In the technique described in Patent Document 1, the strength of contact pressure in contact with a finger or the like on the touch panel is determined, and output corresponding to the operation content by the finger or the like is performed according to the contact pressure. . In relation to this, Patent Document 1 describes a configuration in which the slide amount in the display of a map or music list is changed as a function when the slide is performed based on the determination result of the strength of the contact pressure. In this configuration, while the contact pressure changes from “weak” to “strong”, the content of the same function is expanded according to the contact pressure.

On the other hand, for the purpose of simplifying the content of the operation imposed on the user, a completely different function is assigned to the slide described above according to the strength of the contact pressure. There is also. More specifically, for example, as a function of changing the display mode of the map displayed on the screen provided with the touch panel, the area of the map that is the display target is displayed while the “weak press” slide with low contact pressure is performed. A navigation device that can be moved (while maintaining the scale) and performs a process such as a transition of the map to an enlargement mode while a “strong push” slide with a strong contact pressure is performed is conceivable. As another example, for example, the following functions can be considered.
・ Weak → map slide, strong → map rotation,
・ When there is a map screen and music song list on one screen, weak press → map slide, strong press → song list slide In this way, “weak press” and “strong press” for slides on the touch panel When a function assigned to “strong press” is executed after providing a completely different function, the user touches on the determination of “strong press” / “weak press” from the first press of the slide. If a finger or the like is moved (slid) after an operation exceeding the pressure threshold, only the “strong press” function can be executed. In the following description, the pressing operation at the beginning of the slide is simply referred to as “press”.

However, even when the function assigned to “strong press” is executed in the same manner, for example, if a finger or the like is moved immediately after pressing in the “weak press” state (at the beginning of pressing), the movement is performed. The function assigned to the “weak press” operation is executed until the contact pressure threshold is exceeded, and as a result, the function assigned to the “strong press” operation is to be executed. A function contrary to the user's intention (i.e., assigned to the weak press) will be performed. Such an erroneous operation for the user frequently occurs when the slide is performed while being pressed with a finger or the like as in this example. Therefore, the following two methods are conceivable as general methods for solving this problem.
1) The threshold value itself relating to the determination of “strongly pressed” / “weakly pressed” is reduced (shifted to the “weakly pressed” side).
2) After a certain period of time has elapsed since the time of pressing, the determination of “strongly pressed” / “weakly pressed” is made and the previous slide is set to “invalid”.

  However, in the configuration of 1), there is a problem that even if the user intends to press lightly, the number of cases where the user is determined to be “strongly pressed” increases, resulting in an increase in malfunctions. Further, in the configuration of 2), malfunctions caused by the configuration of 1) are reduced, but a desired function (for example, a function assigned to “strong press”) is started after the first press. An unnecessary delay (time lag) occurs, and as a result, there is a problem in that the reactivity of the touch panel is deteriorated. In the following description, the reactivity is simply referred to as “response”. These two problems become fatal defects for products such as touch panels where operability is most important.

  Therefore, the present application has been made in view of the above problems, and one example of the problem is execution of functions not intended by the user (erroneous operation) while improving the response to the touch of the touch panel with the user's finger or the like. And an operation control method for the operation device, an information processing device including the operation device, and a program for the operation device.

  In order to solve the above-described problem, the invention according to claim 1 is an operation device that outputs contact mode information corresponding to a contact mode with respect to a contacted part that is contacted from the outside.

  In order to solve the above-described problem, the invention described in claim 7 is directed to a computer connected to a contacted portion that is contacted from the outside, and the operating device according to any one of claims 1 to 5. To function as.

It is a block diagram which shows schematic structure of the operating device which concerns on embodiment.

  Next, the form for implementing this application is demonstrated using FIG. FIG. 1 is a block diagram illustrating a schematic configuration of the operating device according to the embodiment.

  As shown in FIG. 1, the operating device S according to the embodiment is connected to a contacted part TP that is contacted from the outside, and outputs contact mode information corresponding to a contact mode from the outside with respect to the contacted part TP. It is an operating device. The operating device S includes a pressure detection unit 1, a determination unit 2, and an output unit 3.

  In this configuration, the pressure detection means 1 uses the contact pressure to the contacted part TP during the movement elapsed time, which is the time when the contact position after the start of contact with the contacted part TP has moved in the contact state, as the contact mode. To detect.

  Then, the determination unit 2 determines the contact at the time when the threshold time elapses based on the change in the contact pressure detected by the pressure detection unit 1 during the movement of the contact position from the start of the contact until the preset threshold time elapses. Aspect is determined.

  As a result, the output unit 3 outputs contact mode information corresponding to the contact mode determined by the determination unit 2.

  As described above, according to the operation device S according to the embodiment, the change in the contact pressure detected during the movement of the contact position from the start of the contact to the contacted part TP until the predetermined threshold time elapses. Based on this, the contact mode when the threshold time elapses is determined, and contact mode information corresponding to the determined contact mode is output. Therefore, since the contact mode at the time of the threshold time elapses is determined based on the change in the contact pressure until the predetermined threshold time elapses, the erroneous contact mode is determined while enhancing the response to the contact with the contacted part TP. Can be prevented.

  Next, specific examples corresponding to the above-described embodiment will be described with reference to FIGS. In addition, the Example demonstrated below is an Example at the time of applying this application to the operation control in terminal devices provided with a touch panel, such as a navigation device for vehicles, a tablet-type terminal device, or a smart phone.

  FIG. 2 is a block diagram illustrating a schematic configuration of the terminal device according to the embodiment, FIG. 3 is a diagram illustrating contents of a template according to the embodiment, and FIG. 4 illustrates an operation control process according to the embodiment. It is a flowchart. At this time, in FIG. 2, the same member number as each component in the operating device S is used for each component of the example corresponding to each component in the operating device S according to the embodiment shown in FIG. .

  As shown in FIG. 2, the terminal device SV corresponding to an example of the “information processing device” according to the present application and according to the embodiment is specifically realized as a tablet-type terminal device or a so-called smartphone as described above. Is. The operation device SV according to the embodiment includes a control unit 10 as an example of “execution means” according to the present application, and includes the CPU, a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. A display 12 composed of a liquid crystal display or the like provided with a touch panel TP as an example of the contact portion TP, an operation unit 13 composed of operation buttons other than the touch panel TP, an HDD (Hard Disc Drive) or an SSD (Solid State) Drive unit) and a recording unit 14 as an example of each of the “first storage unit”, “second storage unit”, and “association information storage unit” according to the present application; The interface 15 is connected to a network such as the Internet by wireless or wired. In the recording unit 14, template data T corresponding to a template according to an embodiment to be described later is recorded in a nonvolatile manner. Further, the recording unit 14 includes a process indicating a process as the terminal device SV that is set to be executed when an operation determined to be “strongly pressed” is performed in an operation control process according to an embodiment described later. The association information and the process association information indicating the process as the terminal device SV that is set to be executed when the operation determined as “weak press” in the operation control process is recorded in advance. ing. In this other recording unit 14, a program corresponding to an operation control process according to an embodiment to be described later, a program for controlling a process or operation as the terminal device S other than the operation control process, and the like are stored in advance in a nonvolatile manner. It is recorded.

  On the other hand, the control unit 10 includes a pressure detection unit 1 as an example of the pressure detection unit 1 according to the embodiment, a determination unit 2 as an example of the determination unit 2 according to the embodiment, and an example of the output unit 3 according to the embodiment. Output unit 3 and processing unit 11. At this time, the pressure detection unit 1, the determination unit 2, the output unit 3, and the processing unit 11 may be specifically realized by a hardware logic circuit included in a CPU or the like constituting the control unit 10. Alternatively, the program may be realized by software by causing the CPU or the like to read and execute a program corresponding to a flowchart showing an operation control process according to an embodiment described later. Further, as indicated by a broken line in FIG. 2, the pressure detection unit 1, the determination unit 2, and the output unit 3 constitute an example of the operating device S according to the embodiment.

  In the above configuration, the interface 15 obtains the data between the control unit 10 and the network when acquiring data or the like necessary for processing or operation as the terminal device SV from the network under the control of the control unit 1. Control the exchange of etc.

  In addition, when an operation for designating a process or operation to be performed on the terminal device SV is performed by the user in the operation unit 13, the operation unit 13 generates an operation signal corresponding to the content of the operation. To the control unit 10.

  Furthermore, the touch panel TP detects the contact position on the surface of the finger or the like in the operation when various operations such as the tap by the user using the finger or the like are performed on the surface, and the detected contact position Is generated and output to the control unit 10. At this time, the touch panel TP repeats the detection of the contact position at a preset first time interval, generates the position information indicating the detected contact position at each first time interval, and outputs the position information to the control unit 10. . At this time, in the case of the slide, for example, the touch panel TP generates and outputs position information indicating the contact position at each first time interval within the period during which the slide is performed. In addition to this, the touch panel TP detects a contact pressure by the finger or the like at the contact position, generates pressure information indicating the detected contact pressure, and outputs the pressure information to the pressure detection unit 1 of the control unit 10. That is, the touch panel TP repeats the detection of the contact pressure at a preset second time interval, generates the pressure information indicating the detected contact pressure at each second time interval, and outputs the pressure information to the pressure detection unit 1. . In the case of the slide, for example, the touch panel TP generates and outputs pressure information indicating the contact pressure at each second time interval within a period during which the slide is performed. Here, the second time interval may be the same as or different from the first time interval. The relationship between the first time interval and the second time interval will be described in detail later.

  And the control part 10 is based on the said operation signal from the operation part 13, and the said positional information and the said pressure information from the touch panel TP, the data etc. which were acquired via the interface 15, the program currently recorded on the recording part 14, etc. And the process or operation | movement as the terminal device SV containing the operation control process which concerns on an Example is controlled using the said template data T. FIG.

  At this time, the pressure detection unit 1 acquires, for example, the pressure information indicating the contact pressure by the finger or the like to the surface of the touch panel TP during the slide at every second time interval (that is, the contact pressure is calculated for the second time period). Detected at intervals) and output to the determination unit 2. Based on the pressure information sequentially output from the pressure detection unit 1, the determination unit 2 determines whether the touch to the touch panel TP by the finger or the like that has generated the contact pressure is the strong press or the weak It judges whether it is pushing, and outputs the mode information which shows the touch mode to touch panel TP with a finger etc. including the judgment result to output part 3. Thereby, the output unit 3 outputs the mode information output from the determination unit 2 to the processing unit 11.

  Then, based on the mode information output from the output unit 3, the processing unit 11 executes a process or operation associated in advance with a contact mode such as a finger indicated by the mode information. The processing association information indicating the association at this time is preset and recorded in the recording unit 14. Accordingly, the control unit 10 executes processing or operation as the terminal device SV corresponding to the operation signal output from the operation unit 13 using the processing result of the processing unit 11. Information to be presented to the user in the processing or operation is displayed on the display 12 and presented to the user.

  Next, the operation control process according to the embodiment as a part of the process or operation in the control unit 10 will be specifically described with reference to FIGS.

  First, a template according to an example that is recorded in a nonvolatile manner in the recording unit 14 will be specifically described with reference to FIG.

  As described above, the template according to the embodiment is specifically recorded in the recording unit 14 as the template data T illustrated in FIG. In FIG. 3, the horizontal axis is the time when the finger or the like is in contact with the surface of the touch panel TP, the left end indicates the timing of the press, and the right end indicates the timing when the finger or the like is separated from the surface of the touch panel TP. ing. At this time, releasing the finger or the like from the surface of the touch panel TP is hereinafter referred to as “release”. Also, the time from the press timing illustrated in FIG. 3 to the release timing is usually about 0.5 seconds, for example. On the other hand, the vertical axis in FIG. 3 indicates the contact pressure when a finger or the like is in contact with the touch panel TP, that is, the contact pressure detected by the pressure detection unit 1.

  The template data T according to the embodiment is, as illustrated in FIG. 3, the contact in the “strong pressing” in which the maximum value of the contact pressure during the contact from the press to the release is equal to or greater than a preset threshold pressure. Strong pressing template data TF indicating temporal change of pressure, weak pressing template data TW indicating temporal change of contact pressure in the above-mentioned "weak pressing" in which the maximum value of the contact pressure is lower than the threshold pressure, Is included. Note that the threshold pressure in FIG. 3 may be set experimentally or empirically in advance, for example, or may be changed later by the user based on, for example, personal contact with the touch panel TP. It may be possible.

  Further, the template data T itself may be created, for example, from changes in contact pressure of each of general strong press and weak press, or for each terminal device SV (more specifically, a control unit (not shown) on the touch panel TP). May be. Here, as a method of generating the template data T for each terminal device SV, for example, at the time of initial setting at the time of manufacturing the terminal device SV or starting its use, strong pressing and weakness (as a user's individual) A method of actually pressing a plurality of times, obtaining approximate curves from their average values, and setting them as the strong press template data TF and weak press template data TW illustrated in FIG. A method for obtaining from an operation history for the touch panel TP is exemplified.

  Further, as a specific example of the method using the operation history, when there is no template data T corresponding to the individual user, the general template data T is determined any number of times (for example, ten times), and From this determination result and the change in contact pressure, template data T for the individual user may be generated. More specifically, for example, if the actual operation is performed ten times, if six times are weak press operations and the remaining four times are strong press operations, the average value of the six weak press operations An approximate curve as template data T-W is obtained from the above, and an approximate curve as template data T-F is obtained from the average value of the four strong press operations. The template data TW and the strongly pressed template data TF are preferable. These template data T are also used when determining the threshold time t2 according to the embodiment, as will be described later. This will be described in detail later.

  Next, the operation control process according to the embodiment will be specifically described. Note that the operation control process according to the embodiment is a process executed as a part of the process or operation in the control unit 10 as described above, for example, as an interrupt process for each preset time interval.

  That is, as shown in FIG. 4, when the operation control process according to the embodiment is started, first, the control unit 10 detects the press position of a finger or the like on the surface of the touch panel TP via the pressure detection unit 1 or the like. Then, the press position information indicating the detected press position is acquired (step S1), and time measurement by a timer (not shown) in the control unit 10 is started. Next, when the slide is performed after pressing, the control unit 10 detects a contact position (or a change thereof) of a finger or the like in the slide at each first time interval, and detects each detected contact position. Move position information indicating (or change thereof) is acquired (step S2). At this time, the “move” means that the finger or the like is moved on the touch panel TP while the contact of the finger or the like started by pressing with the touch panel TP is maintained. Next, when the slide is performed, the control unit 10 detects a contact pressure by a finger or the like during the movement through the pressure detection unit 1 in association with each contact position at each second time interval, and Contact pressure information indicating each detected contact pressure is acquired (step S3). Then, the control unit 10 causes the recording unit 14 or the like to temporarily record the press position information, the move position information, and the contact pressure information respectively acquired by the processes of Steps S1 to S3.

  Next, the control unit 10 confirms whether or not it has been determined in the operation control process shown in FIG. 4 whether the slide is a strong press or a weak press (step S4). Note that the determination in step S4 is for performing operation control with priority given to either strong pressing or weak pressing.

  If it is determined in step S4 that the strong press / weak press has already been determined (step S4; YES), then the control unit 10 determines whether or not the determined contact state is a strong press (step S5). When it is determined that it is a strong press (step S5; YES), the control unit 10 refers to the processing association information recorded in the recording unit 14 and refers to the terminal device SV associated with the strong press operation. The process or operation is executed (step S9). Thereafter, the control unit 10 determines whether or not the finger or the like that has been in contact with the surface of the touch panel TP has been released (step S10). If the release has been made (step S10; YES), the terminal device SV is used. Of the original process or operation of the above, or the process or operation associated with the slide, the process or operation after release is entered. On the other hand, if it is determined in step S10 that the release has not been made (step S10; NO), the control unit 10 proceeds to the process of step S2 and continues the operation control process according to the embodiment.

  On the other hand, when it is not determined to be a strong press in the determination in step S5 (step S5; NO), the determination unit 2 of the control unit 10 next determines that the contact pressure indicated by the contact pressure information acquired by the process in step S3 is the contact pressure. It is determined whether or not it is equal to or higher than the threshold pressure illustrated in FIG. 3 (step S6). If the threshold pressure is exceeded (step S6; YES; refer to “TF” in FIG. 3), at that time It is determined that a strong press is being performed (step S7). Thereafter, the control unit 10 proceeds to the process of step S9. In the determination of step S6, when it is determined that the contact pressure indicated by the contact pressure information acquired by the process of step S3 is not equal to or higher than the threshold pressure illustrated in FIG. 3 (that is, less than the threshold pressure) ( Step S6: NO, see “TW” in FIG. 3), the determination unit 2 determines that weak pressing is being performed at that time, and then the control unit 10 performs the above-described processing recorded in the recording unit 14 With reference to the association information, processing or operation as the terminal device SV associated with the weak pressing operation is executed (step S8). Thereafter, the control unit 10 proceeds to the determination in step S10.

  On the other hand, when the strong press / weak press has not been determined in the determination in step S4 (step S4; NO), the control unit 10 next counts the time in the timer from the timing of the first press less than the threshold time t2. It is determined whether or not there is (step S11).

  Here, the threshold time t2 according to the embodiment refers to the threshold time when a strong press / a weak press is not determined by a determination process described later until the threshold time t2 elapses from the timing of the first press. This is a preset elapsed time from the press timing for determining whether to press hard or weakly based on the contact pressure at the timing when t2 has elapsed. The information indicating the threshold time t2 may be recorded in the recording unit 14 in advance, or may be changed later by the user based on, for example, personality about the touch on the touch panel TP. Good. More specifically, for example, when the threshold time t2 is set to 0.3 seconds as the threshold time t2, when the strong pressing or the weak pressing is not determined by the passage of 0.3 seconds from the press timing, Strong pressing or weak pressing is determined based on the contact pressure at the time of 0.3 seconds and the threshold pressure illustrated in FIG. 3 (see FIG. 3). In addition, as a relationship between the first time interval and the second time interval and the threshold time t2, for example, the first time interval and the second time interval are set to be one tenth or less of the threshold time t2. .

  As a method for determining the threshold time t2 according to the embodiment, for example, as illustrated in FIG. 3, in the time from press to release, a value exceeding the threshold pressure in the strong press template data TF (in FIG. 3). The threshold value t2 is the timing at which the exemplified value “5A”) is five times the value less than the threshold pressure (the value “A” exemplified in FIG. 3) in the weakly pressed template data TW at the same timing. Is preferred. Alternatively, for example, the threshold time t2 may be changed according to the processing or operation as the terminal device SV associated with the strong pressing operation and the weak pressing operation. In this case, for example, when a process or operation that requires an improvement in response even if an erroneous operation on the touch panel TP is allowed to some extent is associated, it is preferable to set the threshold time t2 to be small (short). . On the other hand, when a process or operation that requires accuracy of operation is associated even at the expense of the response, it is preferable to set the threshold time t2 to be large (long). In the latter case, the frequency of the operation control process according to the embodiment increases.

  In the determination of step S11, when the elapsed time in the timer is less than the threshold time t2 (step S11; YES), the determination unit 2 of the control unit 10 next indicates the contact pressure information acquired by the process of step S3. It is determined whether or not the contact pressure is equal to or higher than the threshold pressure illustrated in FIG. 3 (step S12). If the contact pressure exceeds the threshold pressure (step S12; YES, see “TF” in FIG. 3). The process proceeds to step S7 and subsequent steps. On the other hand, in the determination of step S12, when it is determined that the contact pressure indicated by the contact pressure information acquired by the process of step S3 is less than the threshold pressure illustrated in FIG. 3 (step S12; NO; reference symbol “T” in FIG. 3). Next, the determination unit 2 predicts the contact pressure based on the speed of movement of the finger or the like until the time is counted in the timer (that is, the speed of movement of the contact position by the finger or the like) (step S13, hereinafter prediction). (Referred to as (A)), prediction of contact pressure based on the acceleration of movement of the finger or the like until the time is counted in the timer (that is, acceleration in the movement of the contact position) (step S14; hereinafter referred to as prediction (B)). The contact pressure is predicted by comparing the correlation between the change in the contact pressure of the finger or the like until the time is counted in the timer and each template data T (step S15; The (C) referred to as.), Performed sequentially.

First, in the process of the prediction (A), for example, the time measured by the timer (that is, the elapsed time from the first press) is “t” (where t <threshold time t2), and the latest detected contact. When the pressure is “p”, the contact pressure at time t1 where 0 ≦ t1 <t is “p1”, and the contact pressure when the threshold time t2 has elapsed is “p2”,
p2 = p + {(p−p1) / (t−t1)} × (t2−t) (1)
When the contact pressure p2 is equal to or higher than the predetermined threshold pressure illustrated in FIG. 3, the determination unit 2 predicts that a strong pressing operation is performed when the threshold time t2 has elapsed. On the other hand, when the contact pressure p2 calculated by the formula (1) is less than the threshold pressure, the determination unit 2 predicts that a weak pressing operation is performed when the threshold time t2 has elapsed.

Next, in the process of the prediction (B), for example, the time measurement by the timer is “t”, the contact pressure change speed at time t is “v”, and the speed at time t1 where 0 ≦ t1 <t is set. When “v1” is set and the contact pressure when the threshold time t2 has elapsed is “p2 _a ”,
p2 _a = v × t + (1/2) × (v−v1) / (t−t1) × (t2−t) ² (2)
If made contact pressure p2 _a is equal to or greater than the threshold pressure, the determination unit 2 predicts an operation of pressing strength during a threshold time t2 elapsed is performed. On the other hand, when the contact pressure p2 _a calculated by the above equation (2) is less than the threshold pressure, the determination unit 2 predicts that a weak pressing operation is performed when the threshold time t2 has elapsed.

  Finally, in the process of the prediction (C), for example, the first correlation between the change in the contact pressure indicated by the strong press template data TF and the change in the actual contact pressure until the time is measured by the timer, Based on the second correlation degree between the change in the contact pressure indicated by the weakly pressed template data TW and the actual change in the contact pressure until the time is measured by the timer, the determination unit 2 determines that the threshold time t2 has elapsed. It is predicted whether a strong pressing operation or a weak pressing operation will be performed. More specifically, when the first correlation degree is greater than the second correlation degree, the determination unit 2 predicts that a strong pressing operation is performed when the threshold time t2 has elapsed, and the first correlation degree is the second correlation degree. If it is smaller than the correlation degree, it is predicted that a weak pressing operation will be performed when the threshold time t2 has elapsed, and if the first correlation degree and the second correlation degree are equal, it is assumed that the contact mode cannot be predicted.

  Next, the determination unit 2 performs prediction (determination) of strong pressing / weak pressing at the time of the threshold time t2 using the prediction results of Steps S13 to S15 (Step S16). That is, the determination unit 2 determines the threshold time when all of the predictions (A) to (C) are predictions of “strongly pressed” (step S16; (A), (B), and (C) all strongly predicted). It is predicted (determined) that a strong pressing operation is performed when t2 has elapsed, and the process proceeds to step S7 to execute subsequent processing. On the other hand, if it is determined in step 16 that all of the predictions (A) to (C) are “weak press” predictions (step S16; (A) (B) (C) all weak press predictions), determination is made. The unit 2 predicts (determines) that a weak pressing operation is performed when the threshold time t2 has elapsed (step S17), and proceeds to the process of step S8. On the other hand, when any of the predictions (A) to (C) is different from the other predictions in step 16 (step S16; other), the determination unit 2 determines that the current time (before the threshold time t2 has elapsed). Assuming that determination of strong press / weak press is impossible (step S20), the process proceeds to step S10 in order to execute the operation control process according to the embodiment again.

  Next, in the determination of step S11, when the elapsed time in the timer is equal to or greater than the threshold time t2 (step S11; NO), the determination unit 2 of the control unit 10 then performs a process other than the prediction in steps S13 to S15. The contact pressure when the threshold time t2 has elapsed is determined by an arbitrary or predetermined method (step S18 and step S19), and when the determination result is a strong pressing operation (step S19; YES), the control unit 10 The process proceeds to step S9. On the other hand, if it is determined in step S19 that the determination result in step S18 is a weak pressing operation (step S19; NO), the control unit 10 proceeds to the process in step S8. Note that, since the threshold time t2 has elapsed at the time of transition to the processing of step S18 (see step S11; NO), the contact pressure at the time (in the moment of progress) is greater than or equal to the threshold pressure. It is determined that the operation is a strong press (step S19; refer to YES), and when the contact pressure is less than the threshold pressure, it is determined that the operation is a weak press (step S19; refer to NO). Therefore, either the strong pressing operation or the weak pressing operation is always determined by executing the processing in step S18 and the determination in step 19 described above.

  As described above, according to the operation control processing according to the embodiment, during the movement of the contact position on the touch panel TP from the start of the touch to the touch panel TP until the predetermined threshold time t2 elapses (that is, the move). Based on the detected change in the contact pressure, the contact pressure at the time when the threshold time t2 has elapsed is predicted (determined), and the process or operation corresponding to the determined contact pressure is executed. It is possible to prevent an erroneous determination of the contact mode while increasing.

  In the process of the prediction (C), the contact pressure at the time when the threshold time t2 has elapsed is either strongly pressed or weakly pressed based on two correlations for the strongly pressed template data TF and the weakly pressed template data TW. Therefore, it is possible to more accurately determine and execute a corresponding process or operation.

  Further, using either the prediction (A) process or the prediction (B) process, the contact pressure can be determined more accurately and the corresponding process or operation can be executed.

  Furthermore, when the processing association information indicating the processing or operation associated with the strong pressing operation or the weak pressing operation is recorded in the recording unit 14 in advance, the processing or operation according to the user's intention is reacted. It can be carried out with good accuracy.

  In the determination of step S16 in the operation control process according to the above-described embodiment (see FIG. 4), if any of the predictions (A) to (C) is a “strong press” prediction, the prediction ( A) to prediction (C) differ depending on the three cases when the prediction is “weak push” or when any of the predictions (A) to (C) is different from the other predictions. In addition to this, the determination in step S16 may be performed using only the prediction (C) processing result. In addition, the determination in step S16 is performed using two of the prediction (C) processing result and the prediction (A) processing result or the prediction (B) processing result. May be.

  Further, the program corresponding to the flowchart shown in FIG. 4 is recorded on a recording medium such as an optical disk or a hard disk, or is acquired via a network such as the Internet, and is read out to a general-purpose microcomputer or the like. It is possible to cause the microcomputer to function as the control unit 10 according to the embodiment.
