Referring to fig. 1, fig. 1 is a block diagram of a mobile terminal 100 according to a preferred embodiment of the present application. The mobile terminal 100 includes a screen wakeup device 110, a memory 120, a processing unit 130, and an acceleration sensor 140.
The memory 120 and the processing unit 130 are electrically connected to each other directly or indirectly to realize data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The screen wakeup apparatus 110 includes at least one software function module which may be stored in the memory 120 in the form of software or firmware (firmware) or solidified in an Operating System (OS) of the mobile terminal 100. The processing unit 130 is used for executing executable modules stored in the memory 120, such as software functional modules and computer programs included in the screen wake-up device 110.
The acceleration sensor 140 is connected to the processing unit 130, and is configured to collect acceleration data of the mobile terminal 100 and send the acceleration data to the processing unit 130, in this embodiment, the acceleration sensor 140 may be a three-axis acceleration sensor.
In one example, the processing unit 130 may include an MCU or an ADSP for processing the data collected by the acceleration sensor 140, and a CPU for running an Android system.
The Memory 120 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (EEPROM), and the like. The memory 120 is configured to store a program, and the processing unit 130 executes the program after receiving the execution instruction.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for waking up a screen of the mobile terminal 100 shown in fig. 1, and the method includes various steps that will be described in detail below.
Step S110, when the screen of the mobile terminal is in a dormant state, periodically acquiring accelerations in at least two directions of the mobile terminal 100, and storing the acquired acceleration data in the at least two directions as a group into a buffer queue, wherein a direction perpendicular to a plane where the screen of the mobile terminal 100 is located is a Z-axis direction, and a direction in which a longer side of the screen of the mobile terminal 100 extends is a Y-axis direction.
In this embodiment, the acceleration sensor 140 may be a multi-axis acceleration sensor 140, and the mobile terminal 100 periodically acquires the current acceleration collected by at least two axes of the multi-axis acceleration sensor 140. Referring to fig. 3, in the present embodiment, a direction perpendicular to the screen of the mobile terminal 100 is a Z-axis direction; on the plane where the screen of the mobile terminal 100 is located, the direction extending along the longer side of the mobile terminal 100 is the Y-axis direction, and the direction extending along the shorter side of the mobile terminal 100 is the X-axis direction.
The mobile terminal 100 is configured with a buffer queue in advance, where the buffer queue is a first-in-first-out (FIFO) queue, for example, the FIFO queue may be a FIFO queue in MCU or ADSP. The mobile terminal 100 stores a set of acceleration data collected at each time to the top of the buffer queue, and discards a set of acceleration data at the bottom of the buffer queue. In the present embodiment, the period of the acceleration sampling may be set to 5 ms.
Step S120, detecting a variation trend of the acceleration rates of the first preset number groups recently acquired from the buffer queue.
In this embodiment, each time new acceleration data is stored in the buffer queue, the mobile terminal 100 performs a smoothing filtering process on the acceleration in each axial direction stored in the buffer queue to filter fine jitter and data noise generated by the acceleration sensor 140 itself.
Then, the variation trend of the acceleration of the first preset number of sets that is obtained recently, for example, after the mobile terminal 100 performs the smoothing filtering process, 50 sets of acceleration data that are collected recently are obtained, and the variation trend of the acceleration of each axis is detected.
In step S130, if it is detected that the acceleration in the Y-axis direction is increased and the acceleration in the Z-axis direction is decreased in the first preset number of acceleration groups, the screen of the mobile terminal 100 is woken up.
After a great deal of research by the inventor, it is found that, in the process of lifting the mobile terminal 100 to a position where the mobile terminal is convenient for the user to view, generally, the Y axis and the Z axis have a certain change rule, referring to fig. 4, when the mobile terminal 100 is placed on a desktop at rest, generally, the acceleration on the Z axis is the current gravitational acceleration, and the accelerations on the Y axis and the X axis are substantially 0. The mobile terminal 100 is generally lifted upward when being lifted and viewed by a user, and finally, a screen of the mobile terminal 100 is at an angle with respect to a horizontal plane. The Y-axis acceleration of the mobile terminal 100 generally increases from 0 during the process of being lifted, and finally stabilizes on a component of the gravitational acceleration. The original acceleration of the Z axis is the current gravitational acceleration, and the original acceleration can be finally stabilized on a component of small gravitational acceleration after being lifted. That is, the Y-axis acceleration increases and the Z-axis acceleration decreases during the lift.
Therefore, in this embodiment, when the mobile terminal 100 detects that there is a trend that the acceleration in the Y-axis direction increases and the acceleration in the Z-axis direction decreases in the first preset number of acceleration groups, it is determined that the mobile terminal 100 is lifted up for viewing, and the screen of the mobile terminal 100 needs to be woken up.
Optionally, in order to make a false determination caused by the shaking of the mobile phone, in this embodiment, the mobile terminal 100 wakes up the screen of the mobile terminal 100 when the mobile terminal detects that the acceleration in the Y-axis direction increases and the acceleration in the Z-axis direction decreases while detecting that the acceleration in the first preset number group does not fluctuate in a large range.
Based on the above design, the solution provided in this embodiment can more accurately and automatically determine the lifting action of the mobile terminal 100 by identifying the trend of the acceleration change in the Y-axis direction and the Z-axis direction. Compared with the scheme that the lifting of the mobile terminal 100 is judged through the initial inclination angle and the termination angle inclination angle in the prior art, the scheme provided by the embodiment can judge the lifting without waiting for the completeness and stability of the lifting action of the mobile terminal 100, the scheme provided by the embodiment can identify the lifting action according to the change of the lifting process, the identification speed is quicker, the user waiting time is shortened, and the user experience is improved.
Further, in some cases, it may be that some shaking of the mobile terminal 100 may cause the acceleration in the Y-axis direction to increase while the acceleration in the Z-axis direction to decrease, which may cause the screen of the mobile terminal 100 to be awoken by mistake.
The inventor finds that the acceleration of the Y axis is not very large during normal lifting, and the instantaneous acceleration of the Y axis may be very large during sudden shaking. Therefore, in this embodiment, if the mobile terminal 100 detects that the acceleration in the Y-axis direction increases and the acceleration in the Z-axis direction decreases in the first preset number of sets of acceleration rates, the preset number of sets of acceleration rates is used as a first detection interval, and it is detected whether the acceleration in the Y-axis direction exceeds a preset first acceleration threshold value in the first detection interval. Wherein the first acceleration threshold may be 1.5 times the acceleration due to gravity.
If it is detected that no acceleration in the Y-axis direction exceeds the first acceleration threshold in the first detection interval, the mobile terminal 100 is considered to be normally lifted, and then the screen of the mobile terminal 100 is woken up.
In another writing case, the user lifting the mobile terminal 100 very quickly may cause the acceleration in the Y-direction to be too large, so in this embodiment, the quick lifting action needs to be recognized.
Specifically, if the mobile terminal 100 detects that the acceleration in the Y-axis direction in the first detection interval exceeds the first acceleration threshold, a second preset number group acceleration stored earlier than the first detection interval in the cache queue is acquired as a second detection interval, and a third preset number group acceleration stored later than the first detection interval in the cache queue is acquired as a third detection interval.
In this embodiment, if it is detected that the acceleration in the Z-axis direction is decreased while the acceleration in the Y-axis direction is increased in the first preset number of sets of acceleration rates, the preset number of sets of acceleration rates is used as a first detection interval (denoted as D1 in this embodiment), and after the D1 is recorded, the mobile terminal 100 still continues to perform the action of acquiring the acceleration and storing the acceleration into the buffer queue.
If it is detected that the acceleration in the Y-axis direction is increased and the acceleration in the Z-axis direction is decreased in the first preset number group acceleration, and it is detected that the acceleration in the Y-axis direction exceeds the first acceleration threshold in the first detection interval, the mobile terminal 100 needs to perform the identification of the fast lift-up action, acquire a second preset number group acceleration stored earlier than the first detection interval in the cache queue as a second detection interval (denoted as D2 in this embodiment), and acquire a third preset number group acceleration stored later than the first detection interval in the cache queue as a third detection interval (denoted as D2 in this embodiment).
Then, the mobile terminal 100 detects the variation tendency of the acceleration in the second detection section and the third detection section.
The inventors have found that the accelerations of the axes of the mobile terminal 100 generally repeatedly fluctuate when the mobile terminal 100 is in motion. For example, referring to fig. 5, in fig. 5, series 1 represents the X-axis acceleration, series 2 represents the Y-axis acceleration, and series Z represents the axis acceleration.
Therefore, if the mobile terminal 100 detects that the number of accelerations greater than the second acceleration threshold in the accelerations of any one of the second detection interval and the third detection interval exceeds a fourth preset threshold, the action of waking up the screen of the mobile terminal 100 is not performed.
The fourth preset threshold may be set to 2, that is, if the acceleration data of any axis has more than 2 large peaks, the data is considered to be shaking, as can be determined from the acceleration data of D0 or D2. In this case, an action of waking up the screen of the mobile terminal 100 is not performed.
In the fast lifting process of the mobile terminal 100, the acceleration of each axis is a process in which the area is stable after one change. For example, referring to fig. 6, in fig. 6, series 1 represents the X-axis acceleration, series 2 represents the Y-axis acceleration, and series Z represents the axis acceleration.
Therefore, if the mobile terminal 100 detects that the number of accelerations greater than the second acceleration threshold in the accelerations of any one of the second detection interval and the third detection interval does not exceed a fourth preset threshold, the screen of the mobile terminal 100 is awakened.
Further, in this embodiment, after waking up the screen of the mobile terminal 100 through step S130, the step S110 is stopped to be continuously executed. In other words, after waking up the screen of the mobile terminal 100, the action of acquiring the mobile terminal acceleration for waking up the screen is stopped.
Based on the design, the scheme provided by the embodiment can automatically recognize general lifting actions and quick lifting actions, and eliminates data interference possibly caused by shaking, so that the recognition of the lifting actions is more accurate.
Referring to fig. 7, the present embodiment further provides a screen wakeup device 110 applied to the mobile terminal 100 shown in fig. 1, which includes an acceleration acquisition module 111, a detection module 112, and an execution module 113.
The acceleration obtaining module 111 is configured to periodically obtain accelerations in at least two directions of the mobile terminal 100 when the screen of the mobile terminal is in a dormant state during sleep, and store the obtained acceleration data in the at least two directions as a group into a buffer queue, where a direction perpendicular to a plane where the screen of the mobile terminal 100 is located is a Z-axis direction, and a direction in which a longer side of the screen of the mobile terminal 100 extends is a Y-axis direction.
In this embodiment, the acceleration obtaining module 111 may be configured to execute step S110 shown in fig. 2, and for a detailed description of the acceleration obtaining module 111, reference may be made to the description of step S110.
Optionally, the detection module 112 is specifically configured to perform a smoothing filtering process on the accelerations in the buffer queue in the axial direction to filter fine jitter and data noise formed by the acceleration sensor 140 itself, and then detect a variation trend of the acceleration speed of the first preset number group that is obtained recently in the buffer queue.

The executing module 113 is configured to wake up the screen of the mobile terminal 100 if it is detected that the acceleration in the Y-axis direction is increased and the acceleration in the Z-axis direction is decreased in the first preset number of acceleration groups.
In this embodiment, the execution module 113 may be configured to execute the step S130 shown in fig. 2, and reference may be made to the description of the step S130 for a detailed description of the execution module 113.
Optionally, the executing module 113 is specifically configured to, if it is detected that the acceleration in the Y-axis direction is increased and the acceleration in the Z-axis direction is decreased in the first preset number of groups of acceleration speeds, use the preset number of groups of acceleration as a first detection interval, and detect whether there is an acceleration in the Y-axis direction in the first detection interval that exceeds a preset first acceleration threshold; if it is detected that no acceleration in the Y-axis direction exceeds the first acceleration threshold in the first detection interval, the screen of the mobile terminal 100 is woken up.
Optionally, the first acceleration threshold is 1.5 times the acceleration due to gravity.
Optionally, the executing module 113 is further configured to, after detecting whether the acceleration in the Y-axis direction in the first detection interval exceeds a preset acceleration threshold, if it is detected that the acceleration in the Y-axis direction in the first detection interval exceeds the first acceleration threshold, obtain a second preset number group acceleration stored earlier than the first detection interval in the cache queue as a second detection interval, and obtain a third preset number group acceleration stored later than the first detection interval in the cache queue as a third detection interval; detecting the variation trend of the acceleration in the second detection interval and the third detection interval; if the acceleration quantity greater than the second acceleration threshold value in the accelerations of any one of the second detection interval and the third detection interval is detected to exceed a fourth preset threshold value, the action of awakening the screen of the mobile terminal 100 is not executed; if the acceleration quantity greater than the second acceleration threshold value in the accelerations of any one of the second detection interval and the third detection interval is detected not to exceed a fourth preset threshold value, awakening the screen of the mobile terminal 100.
