Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flowchart of a prompting method of a mobile terminal according to an embodiment of the present invention, and is applied to a mobile terminal including an off-screen fingerprint identification component and a display screen, as shown in fig. 1, the method includes the following steps:
In the embodiment of the present invention, when the mobile terminal is in the screen locking state, the mobile terminal may detect a variation of a motion parameter of the mobile terminal through a motion detection component of the mobile terminal, for example: the mobile terminal may detect an acceleration change amount thereof, etc. through the acceleration sensor.
The motion parameter variation detected by the mobile terminal may include at least one of a displacement amount, a speed variation, an attitude angle variation, and the like, for example: in a time window with a preset width, the mobile terminal can calculate the angle increment according to the detection data of the gyroscope on the x axis, the y axis and the z axis; calculating to obtain a speed increment according to the detection data of the acceleration sensor on the x axis, the y axis and the z axis; and solving a quaternion updating matrix, namely a strapdown matrix, by using a Bika method, and carrying out normalization processing on the quaternion so as to solve the position variation (namely displacement), the speed variation and the attitude angle variation of the mobile terminal.
In the embodiment of the present invention, when the mobile terminal is in the screen locking state, the mobile terminal may detect whether it meets an unlocking condition, for example: the mobile terminal judges whether a face image of a user exists in an image acquisition area of a front camera of the mobile terminal, if so, the mobile terminal determines that an unlocking condition is met, otherwise, the mobile terminal determines that the unlocking condition is not met; or, the mobile terminal detects whether the capacitance value variation of a preset area of the touch screen is greater than or equal to a preset capacitance value variation threshold, if so, the mobile terminal determines that the unlocking condition is met, otherwise, the mobile terminal determines that the unlocking condition is not met, and the like.
And 102, prompting the fingerprint identification area if the motion parameter variation meets a preset condition.
In the embodiment of the present invention, after the mobile terminal detects the motion parameter variation amount in step 101, the mobile terminal may detect whether the motion parameter variation amount satisfies a preset condition, and prompt the fingerprint identification area when the motion parameter variation amount satisfies the preset condition.
The above-mentioned mobile terminal detects whether the motion parameter variation thereof satisfies the preset condition, which may be that the mobile terminal determines whether the motion parameter variation thereof is smaller than or equal to a certain threshold, for example: the mobile terminal judges whether the displacement is smaller than or equal to a certain threshold value, the threshold value can tend to zero, and if the displacement is smaller than or equal to the threshold value, the motion parameter variation is determined to meet a preset condition, namely the motion parameter variation tends to be static.
In addition, the prompt fingerprint identification area may be a fingerprint identification area that is lighted up by the mobile terminal, or a prompt icon that is displayed in the fingerprint identification area, for example: the fingerprint image is displayed in the fingerprint identification area to prompt the user to input a fingerprint or the like on the fingerprint image.
It should be noted that the fingerprint identification area is an identification area of an off-screen fingerprint identification component arranged on a screen, and when a user inputs a fingerprint in the fingerprint identification area, the off-screen fingerprint identification component can receive an image of the fingerprint input by the user.
Certainly, after the mobile terminal prompts the fingerprint identification area, when the mobile terminal receives a fingerprint image input by a user in the fingerprint identification area, if the mobile terminal determines that the fingerprint image is matched with a preset fingerprint image, the mobile terminal unlocks the display screen.
In this embodiment of the present invention, the mobile terminal may be any mobile terminal including an off-screen fingerprint identification component, for example: a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
In the embodiment of the invention, when the mobile terminal is in a screen locking state, the variation of the motion parameters of the mobile terminal is detected; and if the motion parameter variation meets a preset condition, prompting a fingerprint identification area. Like this, mobile terminal can be when its motion parameter variation satisfies the default condition, and the automatic suggestion fingerprint identification is regional to the user realizes the unblock in the regional input fingerprint of fingerprint identification, and the simple operation just saves time, promotes unblock timeliness.
Referring to fig. 2, fig. 2 is a schematic flow chart of a prompting method of a mobile terminal according to an embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:
The implementation process and the beneficial effects of this step are already described in step 101, and are not described herein again.
Optionally, the motion parameter variation includes at least one of a displacement amount, a speed variation, and an attitude angle variation, so that the mobile terminal can accurately determine whether the mobile terminal is in motion, and prompt the fingerprint identification area.
For example: in a time window with a preset width, the mobile terminal can calculate the angle increment according to the detection data of the gyroscope on the x axis, the y axis and the z axis; calculating to obtain a speed increment according to the detection data of the acceleration sensor on the x axis, the y axis and the z axis; and solving a quaternion updating matrix, namely a strapdown matrix, by using a Bika method, and carrying out normalization processing on the quaternion so as to solve the position variation (namely displacement), the speed variation and the attitude angle variation of the mobile terminal.
In this embodiment of the present invention, if the motion parameter variation of the mobile terminal is detected in step 201, the mobile terminal determines whether the motion parameter variation is greater than or equal to a first threshold, and if the motion parameter variation is greater than or equal to the first threshold, the mobile terminal determines that the motion parameter variation satisfies a preset condition, and the mobile terminal prompts the fingerprint identification area.
For example: taking the above motion parameter variation as a displacement, if the first threshold is 50 mm, and if the detected displacement of the mobile terminal is 60 mm, the displacement is greater than the first threshold, and the mobile terminal prompts the fingerprint identification area.
Optionally, the mobile terminal further includes an infrared sensor, and before step 202, the method may further include: detecting whether the infrared sensor receives incident light corresponding to the emitted light after the infrared sensor emits the emitted light; the step 202 includes: and if the motion parameter variation meets a preset condition and the infrared sensor does not receive incident light corresponding to the emitted light, prompting a fingerprint identification area.
In the embodiment of the invention, after the infrared sensor in the mobile terminal emits the emitted light, the mobile terminal can detect whether the incident light which is formed by the reflection of the emitted light when encountering an obstacle and enters the infrared sensor is received, if the mobile terminal detects the incident light, the mobile terminal can determine that the incident light is shielded, the user does not need to unlock the mobile terminal under the condition, and at the moment, the misoperation can be caused if a fingerprint identification area is prompted; and if the mobile terminal does not detect the incident light and the motion parameter variation meets the preset condition, if the motion parameter variation is larger than or equal to the first threshold, the mobile terminal determines that the user needs to unlock the mobile terminal, and the mobile terminal prompts the fingerprint identification area, so that misoperation of the mobile terminal is reduced, and electric energy is saved.
It should be noted that, in the case where the detected motion parameter is smaller than the first threshold value or the infrared sensor receives the incident light corresponding to the emitted light, the mobile terminal may be configured not to perform any operation, that is, not to perform an operation of prompting the fingerprint identification area.
The detection of whether the infrared sensor receives the incident light corresponding to the emitted light may be performed before step 201, may be performed after step 201, or may be performed simultaneously with step 201, and is not limited herein.
Of course, after detecting that the variation of the motion parameter of the mobile terminal satisfies the preset condition in step 201, for example, is greater than or equal to the second threshold, the mobile terminal may further determine whether the user needs to unlock the mobile terminal through another preset condition, so as to reduce the misoperation of the mobile terminal.
Optionally, step 202 may include: if the motion parameter variation meets a preset condition, detecting the capacitance variation in a preset area of the touch screen; and prompting the fingerprint identification area if the capacitance value variation of the preset area is detected to be larger than or equal to a second threshold value.
In this embodiment, according to the operating principle of the touch screen, if a finger of a user approaches or touches a certain area of the touch screen, a capacitance value of the area in the touch screen changes, and if a capacitance value change amount of the area is greater than a certain threshold, the mobile terminal may determine that the mobile terminal is held by a hand of the user or the user performs an input operation. Therefore, whether the capacitance value variation of the preset area of the touch screen is larger than or equal to the threshold value or not is detected, and when the motion parameter variation meets the preset condition, such as that the motion parameter variation is larger than or equal to the first threshold value, and the capacitance variation of the preset area is larger than or equal to the second threshold value, the mobile terminal prompts the fingerprint identification area, the mobile terminal determines that the user needs to unlock the mobile terminal, so that the fingerprint identification area is prompted, misoperation of the mobile terminal can be reduced, and electric energy is saved.
The preset area of the touch screen may be an area that is designated in advance in the mobile terminal and is easily approached or touched by a finger of a user when the mobile terminal is held by the user, for example: the preset area can be a touch area on the left edge and the right edge of the touch screen when the mobile terminal is displayed on a vertical screen.
It should be noted that, the mobile terminal determines that the user needs to unlock the mobile terminal, or the mobile terminal may determine that the variation of the motion parameter satisfies a preset condition, such as being greater than or equal to a first threshold, the infrared sensor does not receive incident light corresponding to emitted light emitted by the infrared sensor, and the variation of the capacitance in a preset area of the touch screen is greater than or equal to a second threshold, as a condition that the unlocking is satisfied, so as to further reduce misoperation of the mobile terminal.
For example: the mobile terminal preliminarily determines that the user needs to unlock the mobile terminal when detecting that the variation of the motion parameter of the mobile terminal is larger than or equal to a first threshold and the infrared sensor does not receive incident light corresponding to the emitted light, and further detects whether the variation of the capacitance of the preset area of the touch screen of the mobile terminal is larger than or equal to a second threshold, if so, the mobile terminal finally determines that the user needs to unlock the mobile terminal, and the mobile terminal prompts the fingerprint identification area.
Further optionally, after the step 202, the method may further include: if the fingerprint image input by the user in the fingerprint identification area is not received within the preset time length, stopping prompting the fingerprint identification area; judging whether the times of continuously stopping prompting the fingerprint identification area are greater than or equal to the preset times or not; and if the times of continuously stopping prompting the fingerprint identification area are larger than or equal to the preset times, increasing the first threshold value and/or the second threshold value.
In this embodiment, the mobile terminal may increase the first threshold or the second threshold, or both the first threshold and the second threshold when the number of times of continuously stopping prompting the fingerprint identification area is greater than or equal to the preset number of times, so that the mobile terminal determines that the mobile terminal is in motion, and determines that the condition that the mobile terminal is held by the user or a finger of the user approaches is stricter, thereby further reducing the misoperation of prompting the fingerprint identification area by the mobile terminal, and saving electric energy.
The adjusting of the first threshold and/or the second threshold may be that the mobile terminal adjusts the first threshold or the second threshold according to a preset rule, or adjusts the first threshold and the second threshold simultaneously, for example: if the variation of the motion parameter of the mobile terminal is greater than or equal to the first threshold and the variation of the capacitance value is greater than or equal to the second threshold, the mobile terminal prompts the fingerprint identification area, and the mobile terminal may simultaneously increase the first threshold and the second threshold according to a certain ratio, for example, when the mobile terminal continuously lights an icon of the prompt fingerprint identification area for 5 times and does not receive a fingerprint input by the user, that is, the mobile terminal continuously stops lighting the icon of the fingerprint identification area for 5 times, the mobile terminal adjusts the first threshold to 110% of the first initial value and adjusts the second threshold to 110% of the second initial value, where the first initial value and the second initial value are preset fixed values stored in the mobile terminal.
In addition, each time the mobile terminal reaches the prompt fingerprint identification area for the preset number of times without receiving the input fingerprint, the mobile terminal increases the first threshold and the second threshold simultaneously, or only increases the first threshold, or only increases the second threshold, for example: when the mobile terminal stops lighting the icon of the fingerprint identification area for 5 times continuously, adjusting the first threshold value to be 110% of the first initial value, and adjusting the second threshold value to be 110% of the second initial value; when the lighting of the icon of the fingerprint identification area is stopped 10 consecutive times, the first threshold value is adjusted to 120% of the first initial value, and the second threshold value is adjusted to 120% of the second initial value, and so on.
It should be noted that, in the process of continuously prompting the fingerprint identification area by the mobile terminal for N times, if the mobile terminal does not receive the fingerprint image input by the user in the fingerprint identification area within the preset time length each time the fingerprint identification area is prompted, the number of times that the mobile terminal continuously stops prompting the fingerprint identification area is N times, where N is a positive integer greater than or equal to 2; in addition, the above-mentioned continuous N times of stopping prompting the fingerprint identification area should be understood as that the mobile terminal does not receive the fingerprint image input by the user in the fingerprint identification area between any adjacent time points of stopping the fingerprint identification area twice in the process of stopping prompting the fingerprint identification area N times.
Further optionally, step 204 includes: if the fingerprint image input in the fingerprint identification area is detected to be received within the preset time, detecting whether the received fingerprint image is matched with a preset fingerprint image; if the received fingerprint image is matched with a preset fingerprint image, adjusting the first threshold value to a first initial value and/or adjusting the second threshold value to a second initial value, wherein the first threshold value is larger than the first initial value, and the second threshold value is larger than the second initial value.
In this embodiment, when the mobile terminal is successfully unlocked, and when it is detected that at least one of the first threshold and the second threshold is greater than the corresponding initial value, the mobile terminal may adjust the threshold greater than the corresponding initial value of the first threshold and the second threshold to the corresponding initial value, for example: if the first threshold is larger than the first initial value and the second threshold is larger than the second initial value, the mobile terminal simultaneously adjusts the first threshold to the first initial value and adjusts the second threshold to the second initial value so as to improve the timeliness of prompting the fingerprint identification area when the mobile terminal subsequently meets the unlocking condition.
In addition, if the fingerprint input in the fingerprint identification area is received within the preset time period, after detecting whether the received fingerprint image is matched with a preset fingerprint image, the method may further include: and if the received fingerprint image is not matched with the preset fingerprint image, sending a prompt message for prompting to adjust the fingerprint input position and the pressing strength.
In this embodiment, when the mobile terminal detects that the fingerprint image input by the user does not match the preset fingerprint image, for example: when detecting that the definition of the fingerprint image input by the user is lower than the definition threshold or the fingerprint image is incomplete, the mobile terminal sends a prompt message to prompt the user to adjust the fingerprint input position and/or the pressing force, so that the fingerprint identification success rate of the mobile terminal can be improved.
In the embodiment of the invention, when the mobile terminal is in a screen locking state, the variation of the motion parameters of the mobile terminal is detected; if motion parameter variation is greater than or equal to the first threshold value, then indicate the fingerprint identification area, thereby make mobile terminal realize automatic suggestion fingerprint identification area according to its motion state, make the simple operation and save time, promote the unblock timeliness.
