These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.

In order to solve the problem that the amount of transmitted information is large due to the fact that the touch area is represented by the resolution and the problem that the actual touch area cannot be represented due to the fact that the touch area is represented by the preset proportion range in the related art, the embodiment of the disclosure provides a touch area obtaining method. The touch area obtaining method of the embodiment of the disclosure can be applied to an intelligent device, where the intelligent device refers to any device, instrument or machine with computing processing capability, for example, the intelligent device may be a device with a touch screen, such as a smart phone, a smart tablet, a computer, an electronic whiteboard, or a smart home product. In the disclosure, the smart device includes a touch module, the touch module includes a plurality of sensors, the sensors have the same size and are uniformly arranged in sequence to form a sensor matrix, and the formed sensor matrix corresponds to the touch screen, so that the touch module can respond based on a touch action of a user on the touch screen.

As shown in fig. 1, fig. 1 is a flowchart illustrating a touch area acquisition method according to an exemplary embodiment of the present disclosure, where the smart device includes a processor, and the method may be executed by the processor and includes:

in step S101, after the user performs a touch action, the number of triggered sensors on the touch module is determined.

In step S102, a touch area is determined based on the number of triggered sensors and a pre-stored sensor size.

In step S101, when a user performs a touch action, such as clicking or sliding, on a touch screen of the smart device, a sensor on the touch module generates a touch signal based on the touch action, the touch module acquires the touch signal and notifies the number of sensors triggered by a processor of the smart device according to the touch signal, that is, the touch module may correspondingly acquire the number of triggered sensors according to the number of generated touch signals, so that the processor determines the number of triggered sensors on the touch module after the user performs the touch action. In the step, only the parameter of the number of triggered sensors needs to be obtained from the touch module, so that the information quantity needing to be transmitted by the touch module is obviously reduced; the specific type of the sensor is not limited in any way, the sensor can generate a touch signal based on a touch action of a user, and the specific type can be specifically set according to actual conditions.

In one possible implementation, the touch module may transmit data to the processor of the smart device in a data transmission format of the maximum number of sensors triggered in the x-axis direction and the maximum number of sensors triggered in the y-axis direction, i.e., the number of triggered sensors determined by the processor includes the maximum number of sensors triggered in the x-axis direction and the maximum number of sensors triggered in the y-axis direction in a preset two-dimensional coordinate system, in one example, the touch module transmits data to the smart device in the format of (1; 2), it is understood that the specific representation meaning of each parameter may be set according to the actual situation, such as the data format (1; 2), in one case, the x-axis direction may be represented by a first parameter, and the y-axis direction may be represented by a second parameter, in another case, the first parameter may also represent the y-axis direction, and the second parameter represents the x-axis direction, and in the first case, the number of sensors triggered in the x-axis direction is 1, the y-axis direction is represented by a second parameter representing the y-axis direction, and the number of sensors triggered in the x-axis direction is 352, but the final trigger information is obtained by the present embodiment, the number of triggered sensors is 352, and the trigger information is reduced by the present embodiment.

In another possible implementation manner, the touch module may transmit an arrangement number of the triggered sensors or coordinates in a preset two-dimensional coordinate system to a processor of the smart device, so that the processor may determine the number of the triggered sensors based on the arrangement number or the number of the coordinates, please refer to fig. 2, which illustrates an example in which the touch module transmits coordinates, for example, a sensor matrix (7 × 5) is formed on the touch module, and if the sensors triggered by the touch action of the user are sensors in a black area, an abscissa is represented by a first parameter, and a ordinate is represented by a second parameter, the touch module transmits coordinate information (4, 3; 4, 4; 5, 4; 6,4) to the smart device, which indicates that 4 coordinates are triggered, so that the smart device may determine the number of the triggered sensors based on the number of coordinates.

In one embodiment, when a touch portion of a user contacts a touch screen, a sensor corresponding to the touch position of the user generates a touch signal, but there is a case that: although the touch part of the user does not actually contact the sensor corresponding to the edge of the touch part of the user, the sensors may also generate weak touch signals due to the approach of the touch part of the user, in the disclosure, the touch module compares the signal quantity of the touch signals generated by the sensors with a preset threshold value, and then the sensor with the signal quantity of the touch signals larger than the preset threshold value is taken as a triggered sensor, so that the number of the actually triggered sensors can be accurately determined, and the detection accuracy is improved; the specific value of the preset threshold value is not limited in any way, and can be specifically set according to actual conditions.

In step S102, the intelligent module determines a touch area based on the number of triggered sensors and the pre-stored sensor sizes after determining the number of triggered sensors, wherein the size of the sensors can be determined according to the type of the selected sensor, which is not limited by the present disclosure, for example, the size of a single sensor is 1mm × 1mm, the determined number of triggered sensors is 2, and the touch area is 2mm²Therefore, the actual touch area is determined, and the acquired touch area is more accurate.

The intelligent device determines the number of triggered sensors on the touch module after a user performs a touch action, then determines the touch area based on the number of triggered sensors and the pre-stored sensor size, and only needs to obtain the parameter of the number of triggered sensors from the touch module, so that the information quantity required to be transmitted by the touch module is reduced, and the acquired touch area is more accurate based on the number of sensors and the size of the sensors.

FIG. 3 is another flow chart diagram illustrating a touch area acquisition method according to an exemplary embodiment of the present disclosure. Fig. 3 depicts aspects of the present disclosure in more detail with respect to fig. 1.

As shown in fig. 3, the method may be applied to the smart device and executed by a processor of the smart device, and includes the steps of:

in step S301, after a user performs a touch action, determining the number of triggered sensors on the touch module; similar to step S101 in fig. 1, the description is omitted here.

In step S302, determining a touch area based on the number of triggered sensors and a pre-stored sensor size; similar to step S102 in fig. 1, the description is omitted here.

In step S303, based on whether the touch area is greater than or equal to a preset area threshold, different functions are executed; if the touch area is larger than or equal to a preset area threshold, judging that the palm touches, and executing a function corresponding to the palm touch; and if the touch area is smaller than a preset area threshold, judging that the finger touches, and executing a function corresponding to the finger touch.

In step S303, after obtaining a touch area corresponding to a touch action of a user, the smart device further determines whether the touch area is greater than or equal to a preset area threshold, if the touch area is greater than or equal to the preset area threshold, determines that the user touches the smart device with a palm, and executes a function corresponding to the palm touch, and if the touch area is less than the preset area threshold, determines that the user touches the smart device with a finger, and executes a function corresponding to the finger touch.

In an embodiment, the intelligent terminal may further determine, based on the touch action and the touch area, a corresponding trigger event, for example, multiple types of the touch action, such as a click, a slide, or a long press, and determine, based on the type of the touch action and the size of the touch area, a corresponding trigger event, it may be understood that the specific function setting of the trigger event is not limited in any way, and may be specifically set according to an actual situation, for example, when the touch area is greater than or equal to a preset area threshold value and is determined as a palm touch, the corresponding trigger event is further determined based on the type of the touch action, for example, when a palm touches, the touch action is a slide, and a screen capture function is executed; under the condition of palm touch, the touch action is taken as long press, a sharing function is executed, and the like; when the touch area is smaller than a preset area threshold, determining that the finger touches the touch screen, and further determining a corresponding trigger event based on the type of the touch action, for example, when the finger touches the touch screen, the touch action is sliding, and a page turning function is executed; in the case of finger touch, the touch action is a click, a link jump function is executed, and the like. More operation options are provided in the embodiment, and convenience of a user in using the intelligent device is improved.

It can be found that after the touch area is obtained, the corresponding trigger event can be set based on the size of the touch area, so that more convenient operation selection is provided for a user, excessive key pressing steps are reduced, and the convenience of the user in using the intelligent device is improved.

FIG. 4 is another flow chart diagram illustrating a touch area acquisition method according to an exemplary embodiment of the present disclosure. Fig. 4 depicts aspects of the present disclosure in more detail with respect to fig. 1.

As shown in fig. 4, the method may be applied to the smart device and executed by a processor of the smart device, and includes the steps of:

in step S401, after the user performs a touch action, determining the number of triggered sensors on the touch module; similar to step S101 in fig. 1, the description is omitted here.

In step S402, determining a touch area based on the number of triggered sensors and a pre-stored sensor size; similar to step S102 in fig. 1, the description is omitted here.

In step S403, a matched input code is obtained according to the touch area, and unlocking is performed.

In step S403, firstly, the user may preset a corresponding relationship between the touch area and the input code, which is not limited in this disclosure, in an example, for example, the input code "1" is set in a first area range, the input code "2" is set in a second area range, and the like, where the setting of the area range may be specifically set according to actual situations, for example, the first area range is set to be smaller than the second area range; then, after the unlocking module obtains the touch area, the matched input code can be obtained according to the touch area and the preset corresponding relation, for example, when the touch area is in the first area range, the corresponding input code "1" is obtained, then the unlocking module unlocks based on the obtained input code, so that the unlocking function is realized under the condition that the password is not exposed, and the unlocking safety is improved.

In an embodiment, the processor of the smart device may further determine the position of each triggered sensor based on the arrangement number of the triggered sensors or the coordinates in the preset two-dimensional coordinate system, and then the processor may determine the touch area based on the position of each triggered sensor, as shown in fig. 5, the processor may divide the touch screen area into several touch areas in advance based on the setting of a program or the selection of a user, wherein the division number of the touch areas may be specifically set according to the actual situation, and the touch area and the corresponding relationship between the touch area and the input code may be preset by the user, in one example, for example, the setting is that the input code "1" is represented in the first area range, the input code "2" is represented in the second area range, the setting is that the input code "1A" is represented in the touch area 1, touch area 2 represents input code "2B", and then after determining the touch area and the touch area, the processor may obtain a matching input code according to the touch area and the touch area, so as to perform unlocking based on the matching input code, for example, if the determined touch area is touch area 2 and the touch area is within the first area range, and according to a possible ordering of touch areas after touch areas, the matching input code is "2B 1". The embodiment provides more forms for acquiring the input code, so that not only is the personalized password setting of the user realized, but also the unlocking safety is further improved.

In one possible implementation, when the touch module transmits data to the processor of the smart device in a data transmission format of the maximum number of triggered sensors in the x-axis direction and the maximum number of triggered sensors in the y-axis direction, the processor may acquire a touch shape and a touch angle with respect to a specified reference position based on the maximum number of triggered sensors in the x-axis direction and the maximum number of triggered sensors in the y-axis direction.

It is understood that the present disclosure does not limit the reference position of the touch angle, for example, the touch angle may be described with respect to the upper left corner of the touch screen, or the touch angle may also be described with respect to the upper edge of the touch screen; the touch shape and the touch angle of the touch screen are not limited in any way, for example, if the maximum number of the acquired sensors triggered in the x-axis direction is equal to the maximum number of the sensors triggered in the y-axis direction, the touch shape may be a square or a circle, and if the maximum number of the sensors triggered in the x-axis direction is not equal to the maximum number of the sensors triggered in the y-axis direction, the touch shape may be a rectangle or an ellipse; furthermore, if the maximum number of the triggered sensors in the x-axis direction is greater than or equal to the maximum number of the triggered sensors in the y-axis direction, the touch angle is touched towards the x-axis direction relative to the designated reference position, and if the number of the sensors in the x-axis direction is less than the number of the sensors in the y-axis direction, the touch angle is touched towards the y-axis direction relative to the designated reference position, in one example, if the touch module transmits data to the smart device in the format of (1; 2), if the first parameter represents the x-axis direction, the second parameter represents the y-axis direction, it indicates that 1 sensor is triggered in the x-axis direction, and 2 sensors are triggered in the y-axis direction, it may be determined that the touch shape is rectangular, and the touch angle is touched towards the y-axis direction; if the first parameter represents the y-axis direction and the second parameter represents the x-axis direction, indicating that 1 sensor is triggered in the y-axis direction and 2 sensors are triggered in the x-axis direction, it can be determined that the touch shape is a rectangle and the touch angle is a touch toward the x-axis direction.

In another possible implementation manner, the smart device can further determine the position of each triggered sensor based on the arrangement number of the triggered sensors or the coordinates in a preset two-dimensional coordinate system, and further determine the touch shape based on the position of each triggered sensor, and determine the touch angle relative to a specified reference position based on the relationship between the positions of each triggered sensor; referring to fig. 2, taking the example that the touch module sends coordinates as an example, the touch module transmits coordinate information (4, 3; 4, 4; 5, 4; 6,4) to the smart device, so that the smart device can determine the positions of 4 triggered sensors based on the coordinate information, further determine the touch shape more accurately based on the positions of the triggered sensors, and accurately determine the touch angle of the triggered sensors relative to a specified reference position based on the relationship between the positions of the triggered sensors, for example, the specified reference position is the upper edge of the touch screen, and the touch angle is inclined to the y-axis direction (or vertical direction) relative to the upper edge of the touch screen by a certain angle.

In an embodiment, the touch area, the touch shape, and the corresponding relationship between the touch angle and the input code may be preset by the user, and of course, the present disclosure does not limit this to any way, and in an example, for example, if the input code "1" is set in the first area range, the input code "2" is set in the second area range, the input code "a" is set in the oval shape, the input code "B" is set in the circular shape, the input code "a" is set in the horizontal direction, the input code "B" is set in the vertical direction, and the like, the processor of the smart device obtains the matched input code according to the touch area, the touch shape, and the touch angle after determining the touch shape and the touch angle relative to the designated reference position, and performs unlocking. The embodiment provides more forms for acquiring the input code, and further improves unlocking safety.

In an embodiment, the user may further preset a corresponding relationship between the touch area, the touch shape, and the touch angle and the input code, and after the user performs a touch action, the processor determines a matched input code based on the determined touch area, touch shape, touch angle, and the corresponding relationship. In the embodiment, only one touch action of the user is needed, the input code with higher safety can be obtained for unlocking operation, so that the operation of the user is facilitated, and the unlocking safety is further improved.

According to the technical characteristics of the touch area-based input code acquisition and matching, the unlocking function can be realized without exposing the password, and the unlocking safety is improved.

In addition, in the related art, the technology for acquiring fingerprints under the screen is usually that the fingerprint module under the screen is exposed for a fixed time under the irradiation of the fingerprint light spot with fixed brightness, so that the light energy required by the fingerprint sensor under the screen is met, and the fingerprint sensor under the screen performs fingerprint acquisition based on the light energy. In view of the above problem, the present application provides a touch area obtaining method, please refer to fig. 6, where fig. 6 is a flowchart illustrating a touch area obtaining method according to an exemplary embodiment of the present disclosure. The touch area obtaining method of this embodiment may be applied to an intelligent device, where the intelligent device further includes an underscreen fingerprint module, and further, the touch area obtaining method may be executed by the underscreen fingerprint module and includes:

In step S602, determining the area of a fingerprint spot based on the number of triggered sensors and the size of a prestored sensor, and performing underscreen fingerprint acquisition; the fingerprint light spot is used for exposing the fingerprint module under the screen.

In step S601, when a user performs a touch action such as clicking or sliding on the touch screen of the smart device, the sensors on the touch module generate touch signals based on the touch action, the touch module acquires the touch signals and notifies the number of the sensors triggered by the fingerprint module under the screen according to the touch signals, that is, the touch module may correspondingly acquire the number of the triggered sensors according to the number of the generated touch signals, so that the fingerprint module under the screen determines the number of the triggered sensors on the touch module after the user performs the touch action. In this step, only the parameter of the number of triggered sensors needs to be obtained from the touch module, so that the information quantity needing to be transmitted by the touch module is obviously reduced.

In one possible implementation, the touch module may transmit data to the under-screen fingerprint module of the smart device in a data transmission format of the maximum number of sensors triggered in the x-axis direction and the maximum number of sensors triggered in the y-axis direction, that is, the number of triggered sensors determined by the under-screen fingerprint module includes the maximum number of sensors triggered in the x-axis direction and the maximum number of sensors triggered in the y-axis direction in a preset two-dimensional coordinate system, in one example, the touch module transmits data to the smart device in the format of (1; 2), it is understood that the specific meaning of each parameter may be set according to the actual situation, such as the data format (1; 2), in one case, the x-axis direction may be represented by a first parameter, the y-axis direction may be represented by a second parameter, in another case, the y-axis direction may also represent the y-axis direction, the x-axis direction may represent the x-axis direction, in the first case, the x-axis direction represents 1, the y-axis direction represents the y-axis direction, and the final triggering information may be obtained by the triggering of the second sensor 352, if the information is 352, the case, the final triggering information is obtained by the present embodiment, the method.

In another possible implementation manner, the touch module may transmit an arrangement number of the triggered sensors or coordinates in a preset two-dimensional coordinate system to an off-screen fingerprint module of the smart device, so that the off-screen fingerprint module may determine the number of triggered sensors based on the arrangement number or the number of coordinates.

In one embodiment, when a touch portion of a user contacts a touch screen, a sensor corresponding to the touch position of the user generates a touch signal, but there is a case that: although the touch part of the user does not actually contact the sensor corresponding to the edge of the touch part of the user, the sensors may also generate weak touch signals due to the approach of the touch part of the user, in the disclosure, the touch module compares the signal quantity of the touch signals generated by the sensors with a preset threshold value, and then the sensor with the signal quantity of the touch signals larger than the preset threshold value is taken as a triggered sensor, so that the number of the triggered sensors can be accurately determined, and the detection accuracy is improved; the specific value of the preset threshold value is not limited in any way, and can be specifically set according to actual conditions.

In step S602, the area of the fingerprint light spot is determined by the underscreen fingerprint module based on the number of the triggered sensors and the size of the prestored sensors, the position of the fingerprint light spot can be a preset position, and then the underscreen fingerprint module performs fingerprint acquisition based on the area of the fingerprint light spot and the preset position, so as to prevent the influence of too large or too small fingerprint light spot on the final fingerprint identification effect, ensure the exposure of the underscreen fingerprint module is proper, so that the acquired fingerprint image has clearer texture when the underscreen fingerprint module performs underscreen fingerprint acquisition, and improve the fingerprint identification precision.

In an embodiment, the under-screen fingerprint module may further determine the position of each triggered sensor based on the arrangement number of the triggered sensor or the coordinates in a preset two-dimensional coordinate system, and then determine the position of the fingerprint light spot according to the position of each triggered sensor, so that the under-screen fingerprint module may perform under-screen fingerprint acquisition based on the determined area of the fingerprint light spot and the position of the fingerprint light spot, so that the under-screen fingerprint module may perform light spot adjustment based on the current touch condition, so that the fingerprint image acquired by the under-screen fingerprint module is clearer and more accurate, and the fingerprint identification accuracy is further improved.

In an embodiment, the under-screen fingerprint module includes a plurality of light-emitting sub-modules, and the fingerprint light spot is generated based on the light-emitting sub-modules, the under-screen fingerprint module may determine the triggering number of the light-emitting sub-modules based on the number of the triggered sensors, and further determine the area of the generated fingerprint light spot; and the under-screen fingerprint module can also quickly determine the trigger positions of the light-emitting sub-modules based on the positions of the various triggered sensors, so as to determine the positions of the fingerprint light spots. The embodiment provides a method for determining the area of the fingerprint light spot based on the position of the fingerprint light spot more simply and quickly, and is beneficial to improving the response speed of the under-screen fingerprint module. It should be noted that, the present application does not limit the light emitting sub-module, for example, the light emitting sub-module may be a light emitting diode.

According to the fingerprint identification method and device, the area of the fingerprint light spot is determined based on the number of the sensors received by the touch module and the size information of the pre-stored sensors, so that the fingerprint module under the screen is exposed in a proper range, the fingerprint image with clear lines is guaranteed to be collected, and the fingerprint identification precision is improved.
