Description

Technical Field

[0001] The present invention is a touch pressure determination method, and more particularly, relates to a touch pressure determination method which is applied to a force touch panel provided with at least two force sensors and can correctly know the position and force of a user's touch pressure operation. Background Art

[0002] Modern people often use laptop computers in their daily lives. In addition to using an external mouse device to operate the laptop computer, users can also use a touch pad conventionally configured on the laptop computer to perform controls and operations such as cursor movement or clicking.

[0003] Compared to the horizontal movement and sliding control of ordinary touchpads, force touch pads or pressure touchpads provide an additional vertical pressing operation method, that is, the user's finger can press down, press hard or press for a long time on the board to activate different control functions, thereby providing a more natural and intuitive control experience compared to existing double-click or multi-touch gestures.

[0004] Unlike ordinary keyboard keys that use a mechanical structure to provide users with a sense of pressure, this type of force touchpad uses several force sensors to first sense the touch pressure of the user's fingers, and then uses a vibration motor to generate a simulated mechanical structure of the press vibration to feedback to the user, so that the user can know that an effective touch has been completed.

[0005] However, in order to effectively sense the user's touch pressure, a certain number of force sensors must be set and evenly distributed in the touch area of ​​the touchpad. The larger the touch area, the more force sensors are needed to compensate for the lack of linearity between the pressure source and the sensor, but this will cause problems in production costs. In addition, when the user is operating, there may be false touches that are not intended by the user. For example, the operation of the right hand is the user's original intention, but the left hand accidentally touches the touch area, which may cause misjudgment, thereby affecting the operation results of the relevant control functions.

[0006] Therefore, how to effectively determine the user's touch pressure to provide subsequent processing and judgment so that the touch pressure control function of the force touch pad can operate correctly is the main purpose of the present invention. Summary of the invention

[0007] The purpose of the present invention is to provide a touch pressure determination method. The touch pressure determination method is applied to a force touch panel provided with at least two force sensors to complete the sensing and determination of corresponding touch pressure operations, thereby being able to correctly know the position and force of each touch pressure operation, so that subsequent related applications or preset functions can be correctly executed in accordance with user needs, and the inconvenience caused by mis-touch can be eliminated.

[0008] The present invention is a touch pressure determination method, which is applied to a force touch panel. The force touch panel has a processing module, a touch plane, a first force sensor and a second force sensor. The method comprises the following steps: allowing the touch plane to receive a first touch operation with a first actual force value, and generating a first touch position corresponding to the first touch operation by the touch plane; generating a first sensing signal value by the first force sensor for the first touch operation, and generating a second sensing signal value by the second force sensor for the first touch operation; summing the first sensing signal value and the second sensing signal value by the processing module to generate a total sensing signal value; obtaining a first correction force value for the first touch position by the processing module; obtaining a first correction signal value of the first force sensor for the first touch position by the processing module, and obtaining a second correction signal value of the second force sensor for the first touch position by the processing module; summing the first correction signal value and the second correction signal value by the processing module to generate a total correction signal value; and obtaining the first actual force value by the processing module according to the ratio of the total sensing signal value to the total correction signal value being the same as the ratio of the first actual force value to the first correction force value.

[0023] The following embodiments are provided for detailed description. The embodiments are only used as examples and do not limit the scope of the invention. In addition, the drawings in the embodiments omit unnecessary elements or elements that can be completed by conventional techniques to clearly show the technical features of the invention.

[0024] The implementation of the touch pressure determination method proposed by the present invention is now described using a first embodiment. Figure 1 , is a schematic diagram of an application of a force touch panel 1 using the touch pressure determination method of the present invention. Figure 1 As shown, the force touch panel 1 has a touch plane 10, a first force sensor 11 and a second force sensor 12. The first force sensor 11 and the second force sensor 12 are disposed under the touch plane 10 and are relatively evenly distributed within the range of the touch plane 10.

[0025] In addition, the force touch panel 1 also has a processing module and a vibration module (neither of which are shown in the figure). The processing module signal is connected to the first force sensor 11 and the second force sensor 12 to perform processing and judgment of the touch pressure judgment method of the present invention, and the vibration module can execute the corresponding vibration function according to the processing and judgment results of the processing module.

[0026] As mentioned above, the force touchpad 1 of the present invention can be configured on a computer device (not shown in the figure), especially a laptop computer, and can be a user interface or a control panel of the laptop computer, which is used to provide the user with horizontal movement, sliding control and vertical pressing control of the cursor in the operating system. Of course, the concept of the present invention is not limited to this, and in other embodiments, the force touchpad 1 can also be configured on other electronic devices, such as smart phones, tablet computers or wearable devices.

[0027] Specifically, the computer device may be a conventional electronic device, and the touch pressure determination method of the present invention may be configured as a firmware for execution, or stored in a flash memory as an operating program code for access and execution by the processing module, thereby performing a touch pressure determination function.

[0028] The main purpose of the touch pressure determination method of the present invention is to determine the force of the user's touch pressure operation, especially the touch pressure operation of the finger or even the palm, with a limited number of force sensors. This first embodiment is illustrated by the touch pressure operation of two force sensors 11, 12 and a touch pressure position PA. After the position and force of the user's touch pressure operation are determined, the computer device can effectively confirm the user's operation intention and complete the specified operation. The detailed implementation process is described as follows.

[0029] Please also see Figure 2 , is a flow chart of the first embodiment of the touch pressure determination method proposed by the present invention. First, the touch plane 10 receives a first touch pressure operation with a first actual force value, and the touch plane 10 generates a first touch pressure position PA corresponding to the first touch pressure operation (step S11); secondly, the first force sensor 11 generates a first sensing signal value for the first touch pressure operation, and the second force sensor 12 generates a second sensing signal value for the first touch pressure operation (step S12); then, the processing module adds the first sensing signal value and the second sensing signal value to generate a total sensing signal value (step S13); then, the processing module obtains a first calibration value for the first touch pressure position PA. positive force value (step S14); then, the processing module obtains a first correction signal value of the first force sensor 11 for the first touch position PA, and the processing module obtains a second correction signal value of the second force sensor 12 for the first touch position PA (step S15); then, the processing module adds the first correction signal value and the second correction signal value to generate a total correction signal value (step S16); finally, the processing module calculates the first actual force value according to the ratio of the total sensing signal value to the total correction signal value which is the same as the ratio of the first actual force value to the first correction force value (step S17).

[0030] Regarding the step S11, in this embodiment, the touch plane 10 is used as a component in the force touch panel 1 to sense the horizontal movement and sliding touch operation of the user's finger. Taking capacitive touch as an example, the touch plane 10 has a touch sensing module (not shown in the figure). When the finger touches the panel, the capacitance of the electrostatic field on the panel will change, and the touch sensing module can detect the changed position to reflect the movement of the finger. Therefore, the details of step S11 can be: when the first touch operation occurs on the touch plane 10, the touch sensing module generates the first touch position PA corresponding to the first touch operation on the two-dimensional plane. In other words, the first touch position PA can be regarded as information that can be obtained through the sensing of existing components in the present invention.

[0031] Regarding step S12, in this embodiment, the two force sensors 11 and 12 are independently configured and perform independent sensing, so they will respectively generate a sensing signal value, such as the first sensing signal value and the second sensing signal value. Although the two force sensors 11 and 12 are relatively evenly distributed within the range of the touch plane 10, the user's finger may touch and press at any position within the range of the touch plane 10, such as the first touch position PA. Therefore, it can be understood that when the touch position is closer to a certain force sensor, the sensing signal value generated by the force sensor will be larger; conversely, when the touch position is farther from a certain force sensor, the sensing signal value generated by the force sensor will be smaller, and the two are in a linear relationship. Even if the two force sensors 11 and 12 sense the same touch operation, the sensing signal values ​​obtained respectively may not be exactly the same.

[0032] Regarding step S13, in this embodiment, the sum of the first sensing signal value and the second sensing signal value is designed to be directly added. For example, if the first sensing signal value is 2 million units and the second sensing signal value is 4 million units, the total sensing signal value is 6 million units.

[0033] Regarding steps S14 to S15, in this embodiment, the processing module further has a storage unit (not shown in the figure), which stores a comparison table, and the comparison table stores a set of calibration signal values ​​corresponding to each coordinate on the touch plane 10 of the first force sensor 11 and the second force sensor 12 and a calibration force value corresponding to each coordinate.

[0034] In detail, the force touch panel 1 designed with two force sensors 11 and 12 will be subjected to a calibration procedure before leaving the factory, that is, each touchable point on the touch plane 10 is touched one by one to detect the sensing results of the two force sensors 11 and 12, and the results are recorded in the comparison table. The content of the comparison table records the corresponding information in the order of coordinates (e.g. (x, y)); a calibration force value is recorded for each coordinate, and the two force sensors 11 and 12 will each record a calibration signal value for the same coordinate.

[0035] In other words, because two force sensors 11 and 12 are designed, a certain coordinate in the comparison table will correspond to two calibration signal values, and even if the user performs a touch operation on the same coordinate with different forces, the two calibration signal values ​​remain fixed. In addition, similarly, even if the user performs a touch operation on the same coordinate with different forces, the calibration force value remains fixed.

[0036] Therefore, the details of steps S14 to S15 can be: the processing module searches the comparison table according to the coordinates of the first touch position PA to obtain the first correction force value; and the processing module searches the comparison table according to the coordinates of the first touch position PA to obtain the first correction signal value and the second correction signal value.

[0037] Regarding step S16, in this embodiment, similarly, the sum of the first correction signal value and the second correction signal value is also designed to be directly added. For example, if the first correction signal value is 1 million units and the second correction signal value is 2 million units, the total correction signal value is 3 million units.

[0038] As for step S17, it can be seen from the above description that since the total sensing signal value can be obtained by sensing, and the total correction signal value and the first correction force value can be obtained by looking up a table, the only unknown thing to be found is the first actual force value. One feature of the present invention is that the ratio of the total sensing signal value to the total correction signal value is set to be the same as the ratio of the first actual force value to the first correction force value, so that the first actual force value can be found.

[0039] Specifically, assuming that the total sensing signal value is The total correction signal value is The first correction force value is F C , the first actual force value is F, then the above relationship can be written as the following mathematical formula:

[0040]

[0041] Or, it can be expressed as:

[0042]

[0043] A ratio R can be set as:

[0044]

[0045] Therefore, formula (1-2) can be further rewritten as:

[0046]

[0047] For example, according to equations (1-1) to (1-4), if the first calibration force value F C is 200 grams (g), the total sensing signal value The total correction signal value is 6 million units. If it is 3 million units, then the ratio R is 2, so the first actual force value F can be calculated to be 400 grams (g).

[0048] After the first actual force value is obtained, it means that the computer device used has known the force of the first touch operation, and can perform various processing and applications. For example, the processing module can first determine the first actual force value, and when the first actual force value is greater than a touch threshold value, the processing module sends a feedback instruction to the vibration module to make the vibration module vibrate.

[0049] Specifically, this application is to determine whether the user is making an effective touch or just an unintentional touch, and the touch threshold value is designed as the judgment standard, and then the vibration generated by the vibration module (such as a vibration motor) is fed back to the user so that the user can know that an effective touch has been completed. In this way, the device can achieve this technical effect with only two force sensors, and successfully eliminate the possibility of accidental touch by the user.

[0050] Alternatively, the computer device used is loaded with an application program, and when the processing module determines that the first actual force value is greater than the touch pressure threshold value, the processing module issues a running instruction to the application program so that the application program executes a preset function. The application program here can be an existing program that is matched with a general force touchpad, or a program that can be specified by the user; and the preset function is an existing function that corresponds to the application program, or a function that can be specified by the user, all of which can be determined according to the actual application situation.

[0051] The implementation of the touch pressure determination method proposed by the present invention is now described using a second embodiment. Figure 3 , is a schematic diagram of the application of the force touch panel 1 using the touch pressure determination method of the present invention. Figure 1The only difference is that this second embodiment uses two touch positions PA and PB as examples, but still uses two force sensors 11 and 12. Since there are two touch operations, this embodiment is particularly used to distinguish and determine the positions and forces of multiple touch operations to effectively confirm the user's operation intention and complete the specified operation. The detailed implementation process is described below.

[0052] Please also see Figure 4A and Figure 4B , is a flow chart of the second embodiment of the touch pressure determination method proposed by the present invention. First, the touch plane 10 receives a first touch pressure operation with a first actual force value and a second touch pressure operation with a second actual force value, and the touch plane 10 generates a first touch pressure position PA corresponding to the first touch pressure operation and a second touch pressure position PB corresponding to the second touch pressure operation (step S21); secondly, the first force sensor 11 generates another first sensing signal value for the first touch pressure operation and the second touch pressure operation, and the second force sensor 12 generates another second sensing signal value for the first touch pressure operation and the second touch pressure operation (step S22); then, the processing module adds the another first sensing signal value and the another second sensing signal value to generate another total sensing signal value (step S23); then, the processing module obtains a first calibration force value for the first touch pressure position PA and a second calibration force value for the second touch pressure position PB (step S24); Then, the processing module obtains a first correction signal value of the first force sensor 11 for the first touch position PA and a third correction signal value for the second touch position PB, and the processing module obtains a second correction signal value of the second force sensor 12 for the first touch position PA and a fourth correction signal value for the second touch position PB (step S25); Then, the processing module adds up the first correction signal value, the second correction signal value, the third correction signal value and the fourth correction signal value to generate another total correction signal value (step S26); Finally, the processing module calculates the first actual force value and the second actual force value according to the ratio of the other total sensing signal value to the other total correction signal value being the same as the sum of the ratio of the first actual force value to the first correction force value and the ratio of the second actual force value to the second correction force value (step S27).

[0053] Regarding step S21, the second embodiment is similar to the first embodiment, and both use the touch sensing module to generate corresponding touch positions on the two-dimensional plane. The only difference is that the second embodiment has two touch operations at the same time, so there are two touch positions PA and PB.

[0054] Regarding step S22, in this embodiment, although the two force sensors 11 and 12 perform independent sensing, because the two touch operations occur simultaneously, the other first sensing signal value generated by the first force sensor 11 is the result of sensing the two touch operations together; similarly, the other second sensing signal value generated by the second force sensor 12 is also the result of sensing the two touch operations together. It should be noted that although the purpose of this embodiment is to distinguish and find out the actual force values ​​of the two touch operations, it is not necessary to find out the sensing result of a certain force sensor for a certain touch operation separately.

[0055] Regarding step S23 , in this embodiment, the sum of the other first sensing signal value and the other second sensing signal value is designed to be combined into a matrix, for example, the other total sensing signal value is represented as a 2×1 matrix.

[0056] As for the steps S24 to S25, the relevant calibration force values ​​and calibration signal values ​​are also recorded in the comparison table during the calibration procedure, as is the case with the first embodiment. In this embodiment, since there are two touch operations, there are two touch positions PA and PB. If one touch position corresponds to one coordinate, then the two touch operations will correspond to two calibration force values. Also, since two force sensors 11 and 12 are designed, if one touch position corresponds to one coordinate, then the two touch operations will have four calibration signal values.

[0057] Therefore, the details of steps S24 to S25 can be as follows: the processing module searches the comparison table according to the coordinates of the first touch position PA and the coordinates of the second touch position PB to obtain the first correction force value and the second correction force value; and the processing module searches the comparison table according to the coordinates of the first touch position PA and the coordinates of the second touch position PB to obtain the first correction signal value, the second correction signal value, the third correction signal value and the fourth correction signal value.

[0058] Regarding step S26, in this embodiment, similarly, the sum of the first correction signal value, the second correction signal value, the third correction signal value and the fourth correction signal value is also designed to be assembled into a matrix, for example, the other total correction signal value is represented as a 2 by 2 matrix.

[0059] As for step S27, it can be known from the above description that since the other total sensing signal value can be obtained by sensing, and the other total correction signal value, the first correction force value and the second correction force value can be obtained by looking up a table, the only unknown values ​​to be found are the first actual force value and the second actual force value. Another feature of the present invention is that the ratio of the other total sensing signal value to the other total correction signal value is set to be the same as the sum of the ratio of the first actual force value to the first correction force value and the ratio of the second actual force value to the second correction force value, so that the first actual force value and the second actual force value can be found.

[0060] Specifically, let the other total sensing signal value be The other total correction signal value is The first correction force value is F CA , the second correction force value is F CB , the first actual force value is F A , the second actual force value is F B , and referring to equations (1-1) to (1-4) in the first embodiment, the above relationship can be written as the following mathematical formula:

[0061]

[0062] Or, it can be expressed as:

[0063]

[0064]

[0065] Where R is R A and R B The sum of R A is the first actual force value F A The first correction force value F CA The ratio, R B is the second actual force value F B The second correction force value F CB In this embodiment, R in formula (2-1) is also designed to be assembled into a matrix, for example, represented as a 2×1 matrix.

[0066] In addition, the other first sensing signal value is set to S1, the other second sensing signal value is set to S2, and the other total sensing signal value is set to is a 2×1 matrix. Next, let the first correction signal value be S CA1 , the second correction signal value is S CA2 , the third correction signal value is S CB1 , the fourth correction signal value is S CB2, and design the other total correction signal value is a 2 by 2 matrix. Therefore, formula (2-2) can be further rewritten as:

[0067]

[0068] From the above, it can be seen that in formula (2-4), only R A and R B is an unknown number, that is, only the first actual force value F A and the second actual force value F B Since there are only two unknowns among the eight symbols, and the other six are known, after further expansion into simultaneous equations, there is enough information to solve the two unknowns, that is, to find the first actual force value F A and the second actual force value F B size.

[0069] After the first actual force value and the second actual force value are obtained, the computer device used can know the force of the first touch operation and the second touch operation, and can perform various processing and applications. In addition to the effective or invalid touch judgment mentioned in the first embodiment to determine whether to issue the feedback instruction to the user, or to execute the function of the related application program, other applications can also be included.

[0070] For example, since there are two touch operations at the same time, it means that one of them may be an accidental touch that is not intended by the user. Therefore, the following judgment can be designed: when the first actual force value and the second actual force value are both greater than a touch threshold value, and the second actual force value is less than the first actual force value, the processing module ignores the second actual force value.

[0071] In other words, although both touch operations may pass the touch threshold, the touch represented by the smaller force is discarded by comparing the two, so that only the corresponding function of one is executed and the feedback instruction is issued to eliminate possible false touches.

[0072] Regarding the calibration procedure of the above two embodiments, the present invention is designed to detect each touchable point in the form of coordinates and record it into the comparison table. However, in actual operation conditions, the user may not touch the coordinates with recorded data; in this regard, the processing method of the present invention is to look up the table with closer coordinates, or to determine the final selection result by interpolation or related averaging of the records corresponding to all nearby related coordinates.

[0073] It can be seen that the user's touch operation may also have a certain touch area, for example, the first touch position of the first touch operation has a first sensing range, and the second touch position of the second touch operation has a second sensing range. If this situation is used to determine which operation is more in line with the user's original intention, the following judgment can be designed: when the second sensing range is larger than the first sensing range, the processing module ignores the second actual force value.

[0074] In other words, although both touch operations may be normal touch situations, the touch represented by the larger sensing range is still discarded by comparing the touch areas. For example, the touch operation of the finger is retained, and the touch operation of the palm or wrist is discarded, so that only the corresponding function of one is executed and the feedback instruction is issued to eliminate possible false touches.

[0075] The touch pressure judgment method of the present invention can also be further changed according to the concepts disclosed in the above embodiments. For example, three force sensors are set to sense and judge three touch pressure operations; or, more force sensors can be set to perform more accurate touch pressure sensing and judgment. Regardless of the change method, it can be formulated according to the concepts of the above formulas (1-1) to (1-4) and (2-1) to (2-4). It should be noted that since there are several touch pressure operations, there are several unknowns. Therefore, in order to have enough information to calculate the unknown actual force value, the principle of setting is: if there are several force sensors, at most only a few actual force values ​​of touch pressure operations can be calculated.

[0076] It is understandable that if the number of sensors is greater, the matrix of the total sensing signal value on the left side of the equal sign in formula (2-4) will be further expanded; if the number of touch operations is greater, the matrix of the proportional sum on the far right side of the equal sign in formula (2-4) will also be further expanded. However, since the contents of the matrix of the total correction signal value can be obtained by looking up the table, for example, if three force sensors are matched to two touch operations, the total correction signal value is a 3 by 2 matrix. Therefore, under the condition that the number of force sensors is not less than the number of touch operations, there is enough information to find out the proportional relationship, that is, to solve the actual force value of each touch operation.

[0077] In summary, the touch pressure judgment method proposed in the present invention can effectively complete the sensing and judgment of the corresponding touch pressure operation under the condition of setting at least two force sensors, and then can correctly know the position and force of each touch pressure operation, so that subsequent related applications or preset functions can be correctly executed in accordance with user needs and eliminate the inconvenience caused by accidental touch.

[0078] Therefore, the present invention can effectively solve the related problems existing in the prior art, thereby successfully achieving the main purpose of the development of the present disclosure.

[0079] Although the present invention has been disclosed as above by way of embodiments, it is not intended to limit the present invention. A person skilled in the art of the present invention may make various changes and modifications without departing from the concept and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
