For an intelligent device with a touch screen, when a touch module on the intelligent device detects a touch action of a user on the touch screen, corresponding touch coordinates are acquired and reported to a processor, so that the processor can make feedback according to the touch coordinates; in some touch screen touch schemes, the touch module acquires touch coordinates and touch area information, so that the processor can make feedback according to the touch coordinates and the touch area information or transmit the feedback to other modules, and the touch area is usually represented by a resolution or a default scale range (such as a range of 0-1) in the related art.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any or all possible combinations of one or more of the associated listed items.

It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, these information should not be limited to these terms. 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 "at … …" or "responsive to a determination", depending on the context.

In order to solve the problem that the amount of information transmitted is large due to the fact that the touch area is represented by the resolution in the related art 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, 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, wherein the intelligent device refers to any device, instrument or machine with calculation processing capability, and for example, the intelligent device can be a smart phone, an intelligent tablet, a computer, an electronic whiteboard or a device with a touch screen, such as an intelligent home product. In the disclosure, the intelligent device comprises a touch module, the touch module comprises a plurality of sensors, the sensors are identical in size and are uniformly distributed 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 touch actions of a user on the touch screen.

As shown in fig. 1, fig. 1 is a flowchart of a touch area acquisition method according to an exemplary embodiment of the 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 sensors triggered 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, the sensor on the touch module generates a touch signal based on the touch action, and the touch module collects the touch signal and notifies the processor of the smart device of the number of triggered sensors according to the touch signal, that is, the touch module may correspondingly obtain 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 is obtained from the touch module, so that the information quantity required to be transmitted by the touch module is obviously reduced; the specific type of the sensor is not limited, and the sensor can generate a touch signal based on a touch action of a user, and the specific type of the sensor can be specifically set according to actual situations.

In one possible implementation, the touch module may transmit data to the processor of the smart device in a data transmission format of a maximum number of sensors triggered in an x-axis direction and a maximum number of sensors triggered in a 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, for example, the touch module transmits data to the smart device in a (1; 2) format, it may be understood that a concrete representation meaning of each parameter may be set according to an actual situation, such as a data format (1; 2), in one case, the first parameter may represent the x-axis direction and the second parameter represent the y-axis direction; in another case, the first parameter may also represent the y-axis direction and the second parameter represents the x-axis direction; in the first case, 1 sensor is triggered in the x-axis direction, 2 sensors are triggered in the y-axis direction, and in the second case, 1 sensor is triggered in the y-axis direction, 2 sensors are triggered in the x-axis direction, but the number of triggered sensors finally acquired is 2 (1×2=2). The embodiment can obviously reduce the information transmission quantity by transmitting the information in the above mode.

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; referring to fig. 2, for example, the touch module sends coordinates to illustrate that a (7×5) sensor matrix is formed on the touch module, if the sensor triggered by the touch action of the user is a black sensor, the first parameter represents the abscissa and the second parameter represents the ordinate, the touch module transmits coordinate information (4, 3;4,4;5,4;6, 4) to the smart device, and indicates that 4 coordinates are triggered, so that the smart device can determine the number of triggered sensors based on the number of coordinates.

In one embodiment, when a touch portion of a user touches the touch screen, a sensor corresponding to the touch position of the user generates a touch signal, but there is one case that: although the touch part of the user does not actually contact with the sensor corresponding to the edge of the touch part of the user, the sensors may 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 uses the sensor with the signal quantity of the touch signals larger than the preset threshold value as the triggered sensor, so that the number of the sensors actually triggered can be accurately determined, and the detection accuracy is improved; the specific numerical value of the preset threshold value is not limited in any way, and the specific setting can be performed according to actual conditions.

In step S102, after determining the number of triggered sensors, the intelligent module determines a touch area based on the number of triggered sensors and a pre-stored sensor size, wherein the size of the sensors may be determined according to the type of sensor selected, and the disclosure does not limit this, such as a single sensor size of 1mm×1mm, a determined number of triggered sensors of 2, and the touch area of 2mm ² The actual touch area is not only clarified, but also the acquired touch area is more accurate.

The intelligent device determines the number of triggered sensors on the touch module after a user executes a touch action, then determines the touch area based on the number of triggered sensors and the pre-stored sensor size, and only obtains the parameter of the number of triggered sensors from the touch module, thereby not only reducing the information quantity required to be transmitted by the touch module, but also enabling the acquired touch area to be more accurate based on the calculation of the number of the sensors and the size thereof.

Fig. 3 is another flowchart of a touch area acquisition method according to an exemplary embodiment of the present disclosure. Fig. 3 depicts an aspect of the present disclosure in more detail with respect to fig. 1.

As shown in fig. 3, the method can be applied to the intelligent device and executed by a processor of the intelligent device, and comprises the following steps:

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

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

In step S303, after the smart device obtains the touch area corresponding to the touch action of the user, it is further determined 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, it is determined that the smart device is a palm touch, a function corresponding to the palm touch is executed, if the touch area is less than the preset area threshold, it is determined that the smart device is a finger touch, and a function corresponding to the finger touch is executed.

In an embodiment, the intelligent terminal may further determine a corresponding trigger event based on the touch action and the touch area, for example, the touch action has multiple types such as clicking, sliding or long pressing, and the intelligent terminal may determine a corresponding trigger event based on the type of the touch action and the size of the touch area, and it may be understood that the specific function setting of the trigger event is not limited, and the specific setting may be performed according to an actual situation, for example, when the touch area is greater than or equal to a preset area threshold, and it is determined that a palm touches, and further determines a corresponding trigger event based on the type of the touch action, for example, when the palm touches, the touch action is sliding, and performs a screen capturing function; in the case of palm touch, the touch action is a long press, and a sharing function or the like is executed; when the touch area is smaller than a preset area threshold, and the touch area is judged to be touched by a finger, a corresponding trigger event is further determined based on the type of the touch action, for example, when the touch action is sliding and a page turning function is executed; in the case of a finger touch, the touch action is clicking, and a link jump function is executed. In the embodiment, more operation choices are provided, and convenience of a user in using the intelligent device is improved.

It can be found that after the touch area is obtained, a 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 steps are reduced, and convenience of the user when using the intelligent device is improved.

Fig. 4 is another flowchart of a touch area acquisition method according to an exemplary embodiment of the present disclosure. Fig. 4 depicts an aspect 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, a detailed 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, a detailed description is omitted here.

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

In step S403, the user may preset the correspondence between the touch area and the input code, which is of course not limited in any way, and in one example, the input code "1" is represented in the first area range, the input code "2" is represented in the second area range, etc., where the setting of the area range may be specifically set according to the actual situation, for example, the first area range is set to be smaller than the second area range; and then, after the unlocking module acquires the touch area, acquiring a matched input code according to the touch area and a preset corresponding relation, for example, acquiring a corresponding input code '1' when the touch area is in the first area range, and then, unlocking the unlocking module based on the acquired input code, so that the unlocking function is realized under the condition of not exposing a password, 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 a preset two-dimensional coordinate system, then the processor may determine a touch area based on the positions of each triggered sensor, as shown in fig. 5, the processor may divide a touch screen area into several touch areas in advance based on the setting of a program or the selection of a user, where the division number of the touch areas may be specifically set according to the actual situation, and the correspondence between the touch areas and the input codes may be preset by the user, in an example, the input code "1" may be represented in a first area range, the input code "2" may be represented in a second area range, the input code "1A" may be represented in the touch area 1, then the touch area 2 may represent the input code "2B" after the touch area and the touch area are determined, the touch area and the touch area may be matched may be obtained in advance according to the setting of the program, and the touch area may be determined as a matching area based on the touch area may be determined as a matching area after the touch area is determined as the touch area is the first 2. The embodiment provides more modes for acquiring the input codes, so that the personalized password setting of the user is realized, and 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 a maximum number of sensors triggered in an x-axis direction and a maximum number of sensors triggered in a y-axis direction, the processor may acquire a touch shape and a touch angle with respect to a designated reference position based on the maximum number of sensors triggered in the x-axis direction and the maximum number of sensors triggered in the y-axis direction.

It will be appreciated that the disclosure is not limited in any way with respect to the location of the touch angle, such as the touch angle may be described with respect to the upper left corner of the touch screen, or the touch angle may be described with respect to the upper edge of the touch screen; the method and the device have the advantages that the method and the device do not limit the determination rules of the touch shape and the touch angle, for example, if the acquired maximum number of the triggered sensors in the x-axis direction is equal to the maximum number of the triggered sensors in the y-axis direction, the touch shape can be square or round, and the like, and if the maximum number of the triggered sensors in the x-axis direction is not equal to the maximum number of the triggered sensors in the y-axis direction, the touch shape can be rectangular or elliptical, and the like; further, it may be set that if the maximum number of sensors triggered in the x-axis direction is greater than or equal to the maximum number of sensors triggered in the y-axis direction, the touch angle is touched toward the x-axis direction with respect to the designated reference position, if the number of sensors in the x-axis direction is less than the number of sensors in the y-axis direction, the touch angle is touched toward the y-axis direction with respect to the designated reference position, in an example, the touch module transmits data to the smart device in a format of (1; 2), if the first parameter indicates the x-axis direction, the second parameter indicates the y-axis direction, indicating that 1 sensor is triggered in the x-axis direction and 2 sensors are triggered in the y-axis direction, the touch shape may be determined to be rectangular, and the touch angle is touched toward the y-axis direction; if the first parameter indicates the y-axis direction and the second parameter indicates 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, the touch shape can be determined to be rectangular, and the touch angle is toward the x-axis direction.

In another possible implementation manner, the smart device can also 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, further determine the touch shape based on the position of each triggered sensor, and determine the touch angle relative to the designated 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, the smart device can determine the positions of the 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 touch sensor relative to a designated reference position based on the relationship between the positions of the triggered sensors, for example, the designated reference position is the upper edge of the touch screen, and the touch angle is inclined by a certain angle towards the y-axis direction (or the vertical direction) relative to the upper edge of the touch screen.

In an embodiment, the user may also preset the touch area, the touch shape, and the corresponding relation between the touch angle and the input code, which is of course not limited in any way, and in one example, the input code "1" is represented in the first area range, the input code "2" is represented in the second area range, the input code "a" is represented in the oval shape, the input code "B" is represented in the circular shape, the input code "a" is represented in the horizontal direction, the input code "B" is represented in the vertical direction, and so on, and then the processor of the intelligent 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 unlocks. The embodiment provides more input code acquisition modes, and further improves unlocking security.

In an embodiment, the user may further preset a touch area, a touch shape, and a correspondence between a touch angle and an input code, so that 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 correspondence. In this embodiment, only one touch action of the user is required, the input code with higher security can be obtained to perform unlocking operation, so that the user operation is convenient, and the unlocking security is further improved.

It can be found that the technical characteristics of the matched input codes are obtained based on the touch area, so that the unlocking function can be realized without exposing the password, and the unlocking safety is improved.

In addition, in the related art, the under-screen fingerprint acquisition technology generally exposes the under-screen fingerprint module for a fixed time under the irradiation of a fingerprint light spot with fixed brightness, so as to meet the light energy required by the under-screen fingerprint sensor, so that the under-screen fingerprint sensor performs fingerprint acquisition based on the light energy, however, when the touch area of a user and a touch screen is smaller, the exposure is excessive due to the fixed brightness of the fingerprint light spot, so that the acquired fingerprint image cannot be identified due to the fact that the brightness is too large. In view of the foregoing, the present application provides a touch area acquisition method, referring to fig. 6, and fig. 6 is a flowchart of a touch area acquisition method according to an exemplary embodiment of the present disclosure. The touch area acquisition method of the embodiment can be applied to an intelligent device, the intelligent device further comprises an off-screen fingerprint module, and further, the touch area acquisition method can be executed by the off-screen fingerprint module and comprises the following steps:

In step S601, after the user performs a touch action, the number of sensors triggered on the touch module is determined.

In step S602, determining an area of a fingerprint spot based on the number of triggered sensors and a pre-stored sensor size, and performing on-screen fingerprint acquisition; the fingerprint light spots are used for exposing the under-screen fingerprint module.

In step S601, when a user performs a touch action such as clicking or sliding on a touch screen of the smart device, the sensors on the touch module generate a touch signal based on the touch action, the touch module collects the touch signal and notifies the number of sensors triggered by the fingerprint module under the screen according to the touch signal, that is, the touch module may correspondingly obtain the number of triggered sensors according to the number of generated touch signals, so that the fingerprint module under the screen determines the number of 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 is obtained from the touch module, so that the amount of information to be transmitted by the touch module is significantly 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 a maximum number of sensors triggered in an x-axis direction and a maximum number of sensors triggered in a y-axis direction, i.e., 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 a format of (1; 2), it may be understood that a specific meaning of each parameter may be set according to an actual situation, such as a data format (1; 2), in one case, a first parameter may represent the x-axis direction and a second parameter may represent the y-axis direction; in another case, the first parameter may also represent the y-axis direction, and the second parameter the x-axis direction; in the first case, 1 sensor is triggered in the x-axis direction, 2 sensors are triggered in the y-axis direction, and in the second case, 1 sensor is triggered in the y-axis direction, 2 sensors are triggered in the x-axis direction, but the number of triggered sensors finally acquired is 2 (1×2=2). The embodiment can obviously reduce the information transmission quantity by transmitting the information in the above mode.

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 on-screen fingerprint module of the smart device, so that the on-screen fingerprint module may determine the number of the triggered sensors based on the arrangement number or the number of the coordinates.

In one embodiment, when a touch portion of a user touches the touch screen, a sensor corresponding to the touch position of the user generates a touch signal, but there is one case that: although the touch part of the user does not actually contact with the sensor corresponding to the edge of the touch part of the user, the sensors may 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 uses the sensor with the signal quantity of the touch signals larger than the preset threshold value as the triggered sensor, so that the number of the triggered sensors can be accurately determined, and the detection precision is improved; the specific numerical value of the preset threshold value is not limited in any way, and the specific setting can be performed according to actual conditions.

In step S602, the under-screen fingerprint module determines the area of the fingerprint light spot based on the number of triggered sensors and the pre-stored sensor size, where the position of the fingerprint light spot may be a preset position, and then the under-screen fingerprint module performs fingerprint collection based on the area of the fingerprint light spot and the preset position, so as to prevent the fingerprint light spot from being too large or too small to affect the final fingerprint identification effect, ensure the exposure of the under-screen fingerprint module to be moderate, and make the acquired fingerprint image lines clearer when the under-screen fingerprint module performs the under-screen fingerprint collection, thereby being beneficial to improving 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 sensors or the coordinates in the preset two-dimensional coordinate system, and further 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 accurately, so that the fingerprint image acquired by the under-screen fingerprint module is clearer and more accurate, and fingerprint identification precision is further improved.

In an embodiment, the under-screen fingerprint module includes a plurality of light emitting sub-modules, and the fingerprint light spots are generated based on the light emitting sub-modules, so that the under-screen fingerprint module can determine the triggering number of the light emitting sub-modules based on the number of the triggered sensors, thereby determining the area of the generated fingerprint light spots; and the under-screen fingerprint module can also rapidly determine the trigger position of the light emitting submodule based on the positions of the triggered sensors, so as to determine the position of the fingerprint light spot. The embodiment provides a method for simply and rapidly determining the fingerprint light spot area based on the fingerprint light spot position, which is beneficial to improving the response speed of the under-screen fingerprint module. It should be noted that the light emitting sub-module is not limited in this application, for example, the light emitting sub-module may be a light emitting diode or the like.

It can be seen that the area of fingerprint facula is determined based on the number of sensors received from the touch module and the pre-stored size information of the sensors, so that the under-screen fingerprint module is exposed in a proper range, the fingerprint image with clear lines is collected, and the fingerprint identification precision is improved.
