When the area of the contact area is greater than a preset value, the amount of change in the contact area is detected to compare the amount of change with the corresponding threshold value. The touch event is determined to be an effective touch operation or an invalid touch operation according to the comparison result of the change amount and the corresponding threshold value. When it is determined that the touch event is an effective touch operation, an operation event corresponding to the effective touch operation is triggered. When it is determined that the touch event is an invalid touch operation, the event trigger function of the contact area is disabled.

In an embodiment of the present invention, when the area of the contact area is greater than a preset value, the location information of the contact area may be further recorded, and the touch panel is divided into an operable area and an inoperable area according to the location information, wherein The contact area is located in the inoperable area.

In an embodiment of the present invention, after the step of dividing the touch panel into the operable area and the inoperable area, when another touch event is detected from the inoperable area, another touch may be determined. Whether the control event is an effective touch operation, and when it is determined that another touch event is an effective touch operation When it is done, it can also trigger the operation event corresponding to the effective touch operation.

In an embodiment of the present invention, the touch operation data allowed by the currently executing application may be retrieved and stored in the database to determine that the touch event is an effective touch operation. The touch operation data is read from the database to query the operation events corresponding to the effective touch operation.

In an embodiment of the invention, the amount of change described above is a movement change amount or an area change amount.

The invention provides a touch device comprising a touch panel and a processing unit. The processing unit is coupled to the touch panel, and the processing unit triggers a plurality of modules, including a touch detection module, a touch analysis module, and a behavior processing module. The touch detection module receives touch events through the touch panel. The touch analysis module determines whether the area of the touch area in the touch panel is greater than a preset value, and when the area of the contact area is greater than a preset value, detecting a change amount of the contact area to compare the change amount and corresponding The threshold value is used to determine whether the touch event is an effective touch operation or an invalid touch operation. The behavior processing module triggers an action event corresponding to the effective touch operation or an event trigger function of the disabled contact area according to the touch event as an effective touch operation or an invalid touch operation.

In an embodiment of the present invention, the touch analysis module records position information of the contact area, and divides the touch panel into an operable area and an inoperable area according to the position information, wherein the contact area is located in the inoperable area. .

In an embodiment of the present invention, when the touch detection module is self-selectable When another touch event is detected in the operation area, the touch analysis module further determines whether the other touch event is an effective touch operation, so as to notify the behavior when determining that another touch event is an effective touch operation. The processing module triggers an operation event corresponding to the effective touch operation.

In one embodiment of the present invention, the touch device further includes a function recording module for capturing touch operation data allowed by the currently executing application and storing the data to the database. Here, when the touch analysis module determines that the touch event is an effective touch operation, the touch analysis module reads the touch operation data from the data library to query an operation event corresponding to the effective touch operation.

In an embodiment of the present invention, the amount of change described above is a change amount of movement or an amount of change in area.

In FIG. 1 , the electronic device 100 includes a touch panel 110 and processes The unit 120 is coupled to the touch panel 110. In addition, the electronic device 100 further includes a touch detection module 130 , a touch analysis module 140 , and a behavior processing module 150 , and the module can be triggered by the processing unit 120 .

In detail, the touch panel 110 can be disposed on a display panel (not shown), and the user can directly view the image displayed by the display panel through the touch panel 110. The touch panel 110 can have a plurality of sensing blocks (not shown), and the sensing blocks can generate sensing signals according to a user's touch operation. In addition, the touch panel 110 of the embodiment is, for example, a capacitive touch panel or a resistive touch panel.

The processing unit 120 is, for example, a central processing unit (CPU), or other programmable microprocessor (Microprocessor), a digital signal processor (DSP), a programmable controller, and a special application. Application Specific Integrated Circuits (ASICs), Programmable Logic Devices (PLDs), or the like.

In addition, the touch detection module 130, the touch analysis module 140, and the behavior processing module 150 may be code written by a programming language or a separate chip. For example, the touch detection module 130, the touch analysis module 140, and the behavior processing module 150 may be code written by a programming language, and the code is stored in a storage unit (not shown). For processing by the processing unit 120. The above storage unit is, for example, a non-volatile memory, a flash memory or a hard disk. Alternatively, the touch detection module 130, the touch analysis module 140, and the behavior processing module 150 are respectively one or The individual wafers of the plurality of logic gates are combined and coupled to the processing unit 120 to control the respective wafers through the processing unit 120.

In this embodiment, the processing unit 120 can execute various commands or programs on the electronic device 100 to control the overall operation of the electronic device 100, and can be controlled by the touch detection module 130, the touch analysis module 140, and the behavior. The processing module 150 implements a method of operating the touch panel 110. The functions of each module will be described below.

The touch detection module 130 receives the touch event through the touch panel 110. Further, the touch detection module 130 receives a series of sensing signals generated by the touch event from the touch panel 110.

The touch analysis module 140 is configured to determine whether the area of the touch area of the touch event in the touch panel 110 is greater than a preset value. When the area of the contact area is greater than the preset value, the touch analysis module 140 detects the amount of change in the contact area to compare the change amount with the corresponding threshold value, thereby determining whether the touch event is an effective touch operation or an invalid touch. operating. That is to say, the touch analysis module 140 detects whether the amount of change in the contact area meets the corresponding threshold value. In the present embodiment, the amount of change in the contact area is, for example, a movement change amount or an area change amount, but is not limited thereto.

In addition, the touch analysis module 140 can also record the location information of the contact area. Moreover, according to the location information, the touch analysis module 140 can divide the touch panel 110 into an operable area and an inoperable area, wherein the contact area is located in the inoperable area. For example, for the touch event of the touch panel 110 on the operable area, the touch analysis module 140 can directly treat the touch event as an effective touch operation. On the other hand, if the touch event is not operational The touch analysis module 140 further compares the contact area of the touch event with the touch panel 110 and the corresponding threshold value, thereby determining whether the touch event is an effective touch operation.

The behavior processing module 150 triggers an operation event corresponding to the effective touch operation or an event trigger function of the disabled contact area according to the touch event being an effective touch operation or an invalid touch operation. In addition, when the touch event is an effective touch operation, the behavior processing module 150 can also be combined with the effective touch operation transmitted by the touch analysis module 140 according to the touch operation data allowed by the currently executing application.

When the touch analysis module 140 determines that it is an effective touch operation according to the change amount of the touch event, the action processing module 150 can trigger the corresponding operation event (for example, page change).

In addition, the electronic device 100 further includes a function recording module 160. The function recording module 160 is configured to capture the touch operation data allowed by the currently executing application and store the data in the data repository 170. In detail, since the touch operation data allowed by different applications may be different, the function record module 160 can record the touch operation data and the corresponding operation events corresponding to each application through the data library 170. For example, the function recording module 160 can record operation events corresponding to various touch events in different applications, and record touch operation data corresponding to each operation event. For example, an action event triggered by a slide operation, and an action event that triggers the action The amount of change in movement or the amount of change in speed corresponding to this sliding operation, and the like. In this manner, when the touch analysis module 140 determines that the touch event is an effective touch operation, the touch analysis module 140 reads the touch operation data from the data library 170 to query an operation event corresponding to the effective touch operation. .

The operation method of the touch panel will be described below with the electronic device 100 described above. 2 is a flow chart of an operation method according to a first embodiment of the present invention. The operation method in this embodiment is applicable to the electronic device 100 having the touch panel 110.

Referring to FIG. 1 and FIG. 2, in step S201, the electronic device 100 receives a touch event through the touch panel 110. The touch event may be a touch operation performed by the user on the touch panel 110, for example, Press, click, or swipe.

Then, in step S203, the touch analysis module 130 determines whether the area of the touch area of the touch event in the touch panel 110 is greater than a preset value. Specifically, if the area of the contact area is greater than the preset value, the touch analysis module 130 can determine the contact area as a palm rejection, indicating that the touch area may hold the touch by the user. The touch event generated by the panel 110 or the touch event generated by the user accidentally touching the touch panel 110. Here, the user can set the preset value according to requirements.

If the result of the determination in step S203 is NO, the touch area is not the palm touch area, and step S213 is executed to execute the touch event analysis program to trigger the corresponding operation when the touch event is resolved as an effective touch operation. event.

If the result of the determination in step S203 is YES, it indicates that the touch area may be a palm touch area. Therefore, step S205 is further performed, and the touch analysis module 130 detects the change amount of the contact area to compare the change amount with the corresponding threshold value. The amount of change is, for example, the amount of change in movement or the amount of change in area of the contact area.

For example, FIG. 3 is a schematic diagram of a touch event according to a first embodiment of the present invention. In this embodiment, the user uses a hand to hold the touch panel 110 as an example for description. Referring to FIG. 3, the user holds the right side of the touch panel 110 with the palm of the hand. Here, it is assumed that the palm is initially in contact with the contact area 302 of the touch panel 110 (shown by oblique lines). Also, it is assumed that the area of the contact area 302 is larger than a preset value. Accordingly, the contact area 302 is considered to be a palm touch area. Further, in Fig. 3, the contact area 302' is a position at which the thumb moves. That is, while holding the touch panel 110, the user can also perform a sliding operation with the thumb. At this time, the area change amount or the movement change amount between the contact area 302 and the contact area 302' is further calculated by the touch analysis module 140 as a basis for triggering an effective touch operation. For example, it is known to generate a sliding operation by moving the amount of change.

It is to be noted that the touch analysis module 140 can determine the threshold value to be compared with the amount of change in the contact area according to the currently executing application of the electronic device 100. That is to say, for different applications, the touch analysis module 130 can obtain different threshold values to compare with the amount of change in the contact area. In this way, since the touch analysis module 130 can select different threshold values according to different applications, the embodiment can be based on The application produces different judgment results.

Returning to FIG. 2, after comparing the amount of change of the contact area with the corresponding threshold value, in step S207, the touch analysis module 130 determines that the touch event is an effective touch operation according to the comparison result of the change amount and the corresponding threshold value. Or invalid touch operation.

When the touch analysis module 130 determines that the touch operation is effective, as shown in step S209, the behavior processing module 150 triggers an operation event corresponding to the effective touch operation. The touch analysis module 140 can read the touch operation data from the data library 170 to query an operation event corresponding to the effective touch operation. On the other hand, in step S207, the touch analysis module 130 determines that the touch event is an invalid touch operation. At this time, as shown in step S211, the behavior processing module 150 disables the event trigger function of the contact area, so that The behavior processing module 150 does not trigger any operational events in the contact area.

Here, the operation of FIG. 3 is taken as an example, and it is assumed that the application currently executed by the electronic device 100 is a reader. When the user grasps and holds the touch panel 110 by hand, the user performs a sliding operation by using one of the fingers of the hand (such as a thumb) to perform a slide operation when the page of the reader is switched. During the process, the contact areas 302 and 302' of the touch panel 110 are successively contacted. Here, if the amount of movement change between the contact areas 302 and 302' exceeds the corresponding threshold value (for example, 20 pixels), the touch analysis module 130 regards the sliding operation in the touch event as an effective touch. Control operation. Then, the touch analysis module 140 reads the moving direction or coordinate corresponding to the sliding operation from the data library 170 to query the operation event corresponding to the sliding operation. Accordingly, the behavior processing module 150 The operation event of the page switching of the reader can be performed according to this sliding operation.

On the other hand, the page switching of the reader is also taken as an example for explanation. When the user performs a sliding operation to switch the browser page while holding the touch panel 110, if the movement change between the contact areas 302 and 302' corresponding to the sliding operation does not exceed the threshold value (for example, 20 pixels) The touch analysis module 140 regards the sliding operation in the touch event as an invalid touch operation. In other words, the touch analysis module 130 does not perform page switching of the reader according to the sliding operation performed by the user.

Based on the above, when the contact area is greater than the preset value, whether the touch event from the user is an effective touch operation may be determined according to the amount of change of the contact area of the touch panel 110, so as to determine that the touch is effective. Operation, trigger the corresponding operation event. According to this, even in the case where the palm touch area is generated, the operation event can be realized by the touch panel, and the convenience of the user when using the control panel can be improved.

Second embodiment

4 is a flow chart of a method of operation in accordance with a second embodiment of the present invention. This embodiment is a further application of the first embodiment, and is still described herein in conjunction with the electronic device 100 of FIG.

Referring to FIG. 1 and FIG. 4 , in step S401 , the touch detection module 130 receives the touch event through the touch panel 110 . In step S403, the touch analysis module 140 determines whether the area of the contact area of the touch event is greater than a preset value. If the area of the contact area is not greater than the preset value, it means that the palm touch area is not detected, and step S411 is performed to directly perform the touch event analysis process. sequence. Moreover, when the touch event is parsed as an effective touch operation, step S413 is executed to trigger a corresponding operation event.

On the other hand, if the area of the contact area is greater than the preset value, it means that the palm touch area is detected, and in step S405, the touch analysis module 140 records the position information of the contact area. The position information is, for example, a coordinate position of the contact area on the touch panel or the like. Then, in step S407, the touch analysis module 140 divides the touch panel 110 into an operable area and an inoperable area according to the location information, wherein the contact area is located in the inoperable area.

Here, the inoperable area varies depending on the area or position of the contact area. For example, the area value between the inoperable area and the contact area may be proportional, or the inoperable area may be generated around the contact area. The area where the inoperable area is excluded is the operable area. Of course, the user can also set the area of the operable area and the inoperable area or the area on the touch panel 110 according to the requirements of the actual product, which is not limited herein.

After being divided into an operable area and an inoperable area, steps S409 and S415 may be simultaneously performed. In step S409, the touch detection module 130 determines whether another touch event is detected from the inoperable area. In step S415, the touch detection module 130 detects the amount of change in the contact area, as shown in step S415.

When the touch detection module 130 detects another touch event from the inoperable area, as shown in step S411, the touch analysis module 140 directly executes the touch event analysis program to determine whether the touch event is For effective touch operating. Specifically, the other touch event described above is, for example, a user performing a pressing, clicking, or sliding operation in an inoperable area. Generally, in the case where the touch panel 110 is divided into an inoperable area by a touch event, when the touch event is received in the inoperable area, the touch event does not trigger any correlation. Operational event. In the present embodiment, step S411 is further performed. When it is determined that the other touch operation event is an effective touch operation, step S413 is executed, and the action processing module 150 triggers an operation event corresponding to the effective touch operation.

Returning to step S409, if another touch event is not detected in the inoperable area, step S415 is performed. In the present embodiment, steps S415, S417, S419, and S413 are the same as steps S205, S207, S211, and S209 of the first embodiment, and are not described herein again.

For a clearer explanation, an embodiment will be described below. FIG. 5 is a schematic diagram of a touch event according to a second embodiment of the present invention. As shown in FIG. 5, the user grasps the right side of the touch panel 110 with his hand, and forms a contact area 502 (shown by oblique lines) on the touch panel 110. Here, it is assumed that the area of the contact area 502 is larger than a preset value, that is, the contact area 302 is a palm touch area. At this time, the touch analysis module 140 records the position information of the contact area 502, and the touch analysis module 140 divides the touch panel 110 into the operable area 520 and the inoperable area according to the position information of the contact area 502. 510. The contact area bit 502 is located in the inoperable area 504.

In Fig. 5, the contact area 502' is the position where the thumb moves. That is, while holding the touch panel 110, the user can also enter the thumb Line sliding operation. At this time, the area change amount or the movement change amount between the contact area 502 and the contact area 502' is further calculated by the touch analysis module 140 as a basis for triggering an effective touch operation. For example, it is known to generate a sliding operation by moving the amount of change. The method for comparing the amount of change with the threshold value has been described in the first embodiment, and thus will not be described again.

On the other hand, in the case where the hand grasps the contact area 502, if another touch event (for example, a tap event) is detected at the position 504 of the inoperable area 510, the light touch is determined according to the above step S411. The event is an effective touch operation, and the corresponding operation event can be triggered. That is, when the touch analysis module 140 divides the touch panel 110 into an operable area 520 and an inoperable area 510. At this time, if another touch event is detected in the inoperable area 510, and the touch analysis module 140 determines that it is an effective touch operation, the behavior processing module 150 may also trigger the corresponding corresponding to the effective touch operation. Operational event.

Moreover, when it is determined that the touch area 110 is the palm touch area and the touch panel 110 is divided into the operable area 520 and the inoperable area 510, if another touch event is detected at the position 506 in the operable area 520 The touch event parser (ie, the general handler) will also be executed directly. That is, the user can normally perform any effective touch operation in the operable area 520. In summary, in the above embodiment, when the area of the touch area of the touch event received by the touch panel is greater than a preset value, whether the touch event is an effective touch may be determined according to the amount of change of the contact area. The operation is to trigger a corresponding operation event when determining that the touch event is an effective touch operation. Thereby, when the user operates the touch panel Convenience.
