The integrated pressure data includes at least pressure data output by the first pressure sensor and pressure data output by the second pressure sensor. Because the first pressure sensor and the second pressure sensor are located on different planes, and the pressure distribution in the three-dimensional space can be determined by combining the pressure data respectively output by the first pressure sensor and the second pressure sensor, the specific situation of the pressure applied to the terminal equipment 10 can be more comprehensively obtained, the direction of the pressure source can be more accurately determined, the correct identification rate of the keys can be improved, and the non-pressing interference can be eliminated.
Specifically, the terminal device 10 stores the above-described pressing model in advance. Before the terminal device 10 leaves a factory, a preset effective pressing operation, such as a key operation, a touch operation on a designated touch area, and the like, may be applied to the terminal device 10, and standard comprehensive pressure data corresponding to the effective pressing operation may be collected, so as to construct an effective pressing model corresponding to the effective pressing operation according to the standard comprehensive pressure data; and various false touch scenes can be simulated, various false touch operations such as distortion and pressing of an unformed touch area are applied to the terminal equipment 10, standard comprehensive pressure data corresponding to the false touch operations are collected, and a false touch pressing model corresponding to the false touch operations is constructed according to the standard comprehensive pressure data.

In some embodiments, please refer to fig. 4. For convenience of description, the terminal device 10 is further illustrated by taking the handset 20 as an example. A plurality of first mounting regions 211 are spaced apart from each other on the back case 25 of the cellular phone 20, and one or more first pressure sensors 241 are mounted in each of the first mounting regions 211.

This embodiment is more efficient to use when the pressure currently applied by the user is primarily applied to the back shell 25 and display 23 of the handset 20. Specifically, by arranging the first sensor 241 below the display 23 to detect the pressure acting on the display 23, and arranging the other part of the first sensor 242 on the back shell 25 to detect the pressure acting on the back shell 25 in the opposite direction, since the display 23 and the back shell 25 are usually on two surfaces parallel to each other and are perpendicular to the plane of the side frame, a rectangular three-dimensional coordinate system can be determined according to at least one of the display 23 and the back shell 25 and the side frame, and the pressure distribution in the three-dimensional space corresponding to the coordinate system can be determined according to the comprehensive pressure data, and the change of the pressure from the display 23 to the back shell 25 or the change of the pressure from the back shell 25 to the display 23 can be determined, so that the accurate position pressed by the user and the direction of the applied pressure can be more accurately determined, and the recognition rate of the effective key operation and the key mis-touch operation can be further improved, thereby playing a good effect of preventing false touch.
In some embodiments, a back case 25 of the mobile phone 20 is provided with a sub-screen (not shown), and the number of the first pressure sensors 241 is plural, wherein: a part of the first pressure sensor 241 is arranged on the display 23 of the mobile phone 20 and faces the interior of the mobile phone 20; another part of the first pressure sensor 241 is disposed on the side of the sub-screen facing the inside of the cellular phone 20. The secondary screen here is the second screen or the second display screen of the mobile phone 20, and the size and the dimension of the secondary screen are not limited in the present invention.

Specifically, the first sensor 241 is arranged below the display screen 23 to detect the pressure acting on the display screen 23, the second sensor 242 is arranged below the secondary screen to detect the pressure acting on the secondary screen, the display screen 23 and the secondary screen are usually arranged on two surfaces which are parallel to each other, so that a right-angle three-dimensional coordinate system can be determined according to the display screen 23 and the secondary screen, the pressure distribution in a three-dimensional space corresponding to the coordinate system is determined according to comprehensive pressure data, the pressure size and the direction applied to the display screen or the secondary screen can be determined accurately, the accurate position pressed by the user is determined (namely, whether the user presses the display screen or the secondary screen is determined), and a good mistaken touch prevention effect is achieved.
In some embodiments, the second pressure sensor 242 includes at least two strain sensitive elements spaced apart from the side frame 12 of the terminal device 10, or alternatively, the second pressure sensor includes at least two sets of strain sensitive elements spaced apart from the side frame 12 of the terminal device 10. Optionally, one or more strain sensitive elements may be included in each set of strain sensitive elements. The at least two/at least two sets of strain sensitive elements may be disposed on the same side frame 12 of the terminal device 10, or may be disposed on different side frames 12. When two or two sets of strain sensitive elements are arranged at intervals, the number of the side buttons can be increased. For example, function keys 222 such as a power key and a volume key are provided at the side frame 22 of the handset 20, and at least one or a group of strain sensitive elements may be provided under each function key 222. Alternatively, the strain sensitive element may be a pressure sensor 24.
By providing two or two sets of strain sensitive elements spaced apart, the pressure sensing requirements of the plurality of function keys 222 can be met. For example, when two function keys 222 are provided and a group of strain sensing elements is provided below each function key 222, the function key pressed by the user can be accurately identified by using the embodiment, so that the occurrence of false touch is reduced.
The pressure sensor 24 of the present invention may be selected according to the actual situation, and the present invention is not limited thereto. The first pressure sensor 241 and the second pressure sensor 242 are collectively referred to as the pressure sensor 24.
In order to further improve the effect of preventing accidental touch, a control key can be added on the opposite side of the mobile phone 20, under the screen 23 of the mobile phone 20 or on the back shell 25 of the mobile phone 20, and when the control key (not shown) and the function key 222 (the function key includes a power key, a volume key, etc. arranged on the side frame of the mobile phone) are pressed simultaneously, the corresponding function operation is executed. The effect of preventing false touch can be promoted through the mode of combination button.

The pressure touch method implemented by the terminal device 10 may include the following steps: after the program starts, the microprocessor MCU controls the analog-to-digital converter ADC to acquire data of each pressure sensor to form comprehensive pressure data; comparing the current comprehensive pressure data with a pre-established 3D pressing model, and judging whether the user operation corresponding to the comprehensive pressure data is normal pressing operation; if the pressing operation is judged to be normal pressing operation, the pressing event is marked as a normal pressing event, a pressing tag flag is reported to an IC (integrated circuit) end of the terminal equipment 10, and the program is ended; if the abnormal pressing operation is judged, the microprocessor MCU and the analog-to-digital conversion unit ADC enter a sleep state; then the microprocessor MCU and the digital-to-analog conversion unit ADC are awakened at regular time, next round of detection is started, namely when abnormal pressing operation is judged, the current abnormal pressing operation is not responded, and therefore mistaken touch is avoided.
The invention also provides a pressure touch method. Referring to fig. 6, the pressure touch method includes the following steps:
s101, acquiring comprehensive pressure data, wherein the comprehensive pressure data at least comprises pressure data of a first pressure sensor and pressure data of a second pressure sensor. The terminal device 10 will continue with the handset 20 as an example: because the first pressure sensors 241 can be distributed on the display screen 23, the sub-screen, the back shell 25, etc., and the second pressure sensors 242 can be distributed on the functional keys 222 of the side frame 22 and the non-functional keys 22 of the side frame, the pressure data can be summarized to obtain the comprehensive pressure data, so that the pressure applied by the user on the mobile phone 20 can be determined more comprehensively and accurately.
S102, processing the acquired comprehensive pressure data according to a preset pressing model, and determining whether the comprehensive pressure data is valid data.
Specifically, the terminal device 10 stores the above-described pressing model in advance. Before the terminal device 10 leaves a factory, a preset effective pressing operation, such as a key operation, a touch operation on a designated touch area, and the like, may be applied to the terminal device 10, and standard comprehensive pressure data corresponding to the effective pressing operation may be collected, so as to construct an effective pressing model corresponding to the effective pressing operation according to the standard comprehensive pressure data; and various false touch scenes can be simulated, various false touch operations such as distortion and pressing of an unformed touch area are applied to the terminal equipment 10, standard comprehensive pressure data corresponding to the false touch operations are collected, and a false touch pressing model corresponding to the false touch operations is constructed according to the standard comprehensive pressure data. The above-described valid compression pattern and/or false touch compression pattern are stored in the terminal device 10.
In the using process of a user, when the terminal device 10 acquires the comprehensive pressure data, the comprehensive pressure data can be input into a preset effective pressing model for analysis, so as to determine whether the current comprehensive pressure data is effective data; the comprehensive pressure data can also be input into a preset false touch pressing model for analysis, so that whether the current comprehensive pressure data is data generated by false touch or not is determined.
If the currently collected comprehensive pressure data is determined to be valid data through the valid pressing model or determined to be non-false-touch data through the false-touch pressing model, it indicates that the current pressing operation is a valid operation, and the terminal device 10 responds to the pressing operation of the user, for example, generates a key event or executes a touch operation corresponding to at least one pressure parameter of a position, frequency, force, and the like pressed by the user. If the currently collected comprehensive pressure data is determined as non-effective data through the effective pressing model or is determined as false touch data through the false touch pressing model, it indicates that the current pressing operation is a false touch operation, and at this time, the terminal device 10 may not respond to the current pressing operation of the user, so as to avoid generating a false touch event.
S103, if the comprehensive pressure data is valid data, executing a preset instruction corresponding to the comprehensive pressure data.
The effective data comprises effective data judged by an effective pressing model and non-mistaken touch data judged by a mistaken touch pressing model. If the currently collected comprehensive pressure data is determined to be valid data through the valid pressing model or determined to be non-false-touch data through the false-touch pressing model, it indicates that the current pressing operation is a valid operation, and the terminal device 10 responds to the pressing operation of the user, for example, generates a key event or executes a touch operation corresponding to at least one pressure parameter of a position, frequency, force, and the like pressed by the user. For example, assuming that the current integrated pressure data is valid data for pressing a volume key, the current pressing operation is a valid pressing operation on the volume key, and the terminal device 10 will execute a command for increasing or decreasing the volume.
If the currently collected comprehensive pressure data is determined as non-effective data through the effective pressing model or is determined as false touch data through the false touch pressing model, it indicates that the current pressing operation is a false touch operation, and at this time, the terminal device 10 may not respond to the current pressing operation of the user, so as to avoid generating a false touch event.
According to the embodiment, whether the current comprehensive pressure data is effective data or not can be judged by collecting and processing the comprehensive pressure data, and whether the pressing operation of the user at this time is effective operation or not is determined, so that the effective operation can be responded, the error touch operation is not responded, and the probability of error touch occurrence is greatly reduced.

s1021, preprocessing the comprehensive pressure data;
s1022, the preprocessed comprehensive pressure data are transmitted into a preset pressing model, and whether the comprehensive pressure data are effective data or not is determined according to a feedback result of the pressing model. By comparing the current comprehensive pressure data with the standard comprehensive pressure data in the preset pressing model, whether the current comprehensive pressure data is valid data can be determined.
Wherein the preprocessing is data denoising processing including integrated pressure data.
In some embodiments, before the preprocessed data is transmitted into the pressing model, the pressure touch method further includes the following steps: and performing data format conversion processing on the preprocessed comprehensive pressure data according to the input data format requirement of the pressing model.
