Detailed Description

In order to solve the technical problems, the general idea of the embodiment of the present application is as follows:

firstly, acquiring a waveform of an acceleration value of electronic equipment within a first preset time period; then matching the waveform of the acceleration value with a preset waveform, wherein the preset waveform is a waveform corresponding to the motion state of the electronic equipment meeting the screen-lighting condition; and finally, determining whether to control the screen of the electronic equipment to enter a lighting state or not based on the matching result. That is to say, whether the motion state of the electronic device meets the screen-on condition is judged not by the difference algorithm, but whether the motion state of the electronic device meets the screen-on condition is judged by whether the waveform of the acceleration value of the electronic device is matched with the preset waveform, so that the number of sampling points is less limited, the technical effect of reducing time delay is achieved, and the hardware of the electronic device does not need to be improved, so that the cost can be considered; in addition, because the waveforms of different motion states of the electronic equipment are different, the matching reliability can be ensured based on waveform matching; in conclusion, the technical effect of simultaneously considering reliability, cost and response time is achieved by the scheme in the embodiment of the invention;

moreover, if the motion state of the electronic device corresponding to the screen lightening condition is the motion state obtained based on the hand-lifting and screen lightening gesture generated by the user, the waveforms generated by part of the hand-lifting action and the static action can be simultaneously utilized, so that the reliability of the detected hand-lifting and screen lightening gesture is increased, more static time is not needed, and whether the hand-lifting and screen lightening gesture is generated by the user can be judged more quickly.

In order to better understand the technical solutions of the present invention, the following detailed descriptions of the technical solutions of the present invention are provided with the accompanying drawings and the specific embodiments, and it should be understood that the specific features in the embodiments and the examples of the present invention are the detailed descriptions of the technical solutions of the present invention, and are not limitations of the technical solutions of the present invention, and the technical features in the embodiments and the examples of the present invention may be combined with each other without conflict.

In a first aspect, an embodiment of the present invention provides a method for controlling screen lighting, please refer to fig. 1, including:

step S101: acquiring a waveform of an acceleration value of the electronic equipment within a first preset time period;

step S102: matching the waveform of the acceleration value with a preset waveform, wherein the preset waveform is a waveform corresponding to the motion state of the electronic equipment meeting the screen-lighting condition;

step S103: based on the matching result, it is determined whether to control the screen of the electronic device to enter a lighting state.

For example, the solution is applied to an electronic device including a screen, such as: smart watches, bracelets, cell phones, tablet computers, and the like. As shown in fig. 2, a schematic structural diagram of a smart watch is shown, which includes: the system comprises an acceleration sensor, a microcontroller connected with the acceleration sensor and an AP (Application Processor) connected with the microcontroller, wherein the acceleration sensor detects an acceleration value of the electronic equipment and then sends the acceleration value to the microcontroller through a bus (for example, an I2C bus), the microcontroller judges whether a gesture (for example, a hand-lifting screen-watching gesture, a hand-turning screen-off gesture and the like) for controlling a screen is generated by a user or not by processing the acceleration value, if the corresponding gesture is generated, a control instruction corresponding to the gesture is generated, and then the control instruction is sent to the AP, so that the control of the lighting state and the lighting-off state of the screen is realized. In step S101, the acceleration sensor may continuously detect acceleration values of the electronic device in each coordinate axis direction, and further obtain a corresponding waveform for each coordinate axis direction, where a coordinate system of the electronic device includes: the X-axis, the Y-axis and the Z-axis are used for taking the geometric center of the screen as an original point, the X-axis from left to right, the Y-axis from inside to outside and the Z-axis from bottom to top when the screen of the electronic equipment is horizontally punched. When the screen is horizontally and upwards static, the z axis has an output of gravity acceleration, which is recorded as 1g, g is a gravity acceleration unit, and 1g is approximately equal to 9.8m/s2 due to the action of gravity acceleration. The obtained waveform diagrams in the three coordinate axis directions are shown in fig. 3, for example, in which the ordinate indicates the acceleration value (in units of g) and the abscissa indicates the sample point number in fig. 3. Of course, the waveform obtained may be different based on the motion state of the electronic device, and embodiments of the present invention are not illustrated in detail and are not limited.

In a specific implementation process, the motion state of the electronic device meeting the bright screen condition may be a plurality of motion states, for example: a motion state where the motion + is stationary (corresponding to a hand-up motion where the user is in a stationary state), a motion state where the motion + motion speed becomes slow (corresponding to a hand-up motion where the user is in a motion state), and the like. The first preset time period is, for example: the time period corresponding to the user completing the preset operation, which is usually an operation satisfying the bright screen condition (for example, the time spent on the hand-up action when the user is in a static state, the time spent on the hand-up action when the user is in a moving state, and the like), and the first preset time period is, for example: 0.2s, 0.1s, 0.3s, etc., wherein after obtaining the waveform of the acceleration value of the electronic device, the waveform within a first preset time period may be obtained at preset time intervals (e.g., 0.1s, 0.2s, etc.), and then subsequent steps are performed based on the waveform.

In step S102, the motion state of the electronic device corresponding to the bright screen condition may include a plurality of different motion states, for example: a motion state in which the motion + rest, a motion state in which the motion + motion speed becomes slow, and the like, and the obtained preset waveforms are also different. For example: if the motion state of the electronic equipment corresponding to the bright screen condition is a motion state plus a static motion state, the motion state of the electronic equipment is generated firstly and then the motion state is static for a sampling user, an acceleration value of the electronic equipment is detected and obtained in the process that the user generates the motion, a waveform corresponding to the acceleration value is a preset waveform, and under a normal condition, each coordinate axis contains a preset waveform, so that if the coordinate axes comprise an X axis, a Y axis and a Z axis, the preset waveform comprises the preset waveform of the X axis, the preset waveform of the Y axis, the preset waveform of the Z axis and the like. In the preset waveform, the variation of the acceleration value of at least one coordinate axis direction (such as an X axis, a Y axis, a Z axis and the like) is larger than a preset variation value, the preset variation value is, for example, 0.5g, 0.4g, 1g and the like, taking the example shown in fig. 3, in the preset waveform, a part shown in an ellipse 30 in the preset waveform indicates that the electronic equipment is in a static state (such as a user standing upright), a part shown in an ellipse 31 indicates that the electronic equipment is in a motion state (such as the user lifting up his hand), a part shown in an ellipse 32 indicates that the electronic equipment is in a static state (such as a user viewing a screen), when the user standing upright, the acceleration value of the X axis is close to-1 g, and the acceleration value of the; in the process of lifting hands of a user, X, Y, Z triaxial output has large-amplitude change, namely the change quantity is larger than a preset change value; in the process of viewing the screen by the user, the output of an x axis is close to 0, and the output of a z axis is close to 1 g; for other motion states, the preset waveform is obtained in a similar manner, and therefore, the details are not repeated herein.

In step S103, if the matching result indicates that the waveform of the acceleration value matches the preset waveform, it often indicates that the motion state of the electronic device satisfies the screen-on condition, and in this case, the screen of the electronic device may be directly controlled to enter the on state, where the matching of the waveform of the acceleration value and the preset waveform is, for example: the waveforms on at least one coordinate axis can be completely matched with the corresponding preset waveforms, or the waveforms on all the coordinate axes can be completely matched with the corresponding preset waveforms, and the like. In order to detect the motion state of the electronic device more accurately, whether to control the screen of the electronic device to enter the lighting state may be further determined by some subsequent conditions, which are described below.

First, the determining whether to control the screen of the electronic device to enter a lighting state further includes:

For example, the second preset time period is, for example: 0.01s, 0.02s and the like, which are time periods generally corresponding to a part of the electronic device which is close to the end of the first preset time period, and if the motion state of the electronic device which meets the bright screen condition is a motion state of motion + rest, the second preset time period is a time period generally corresponding to the electronic device which is still; if the motion state of the electronic device meeting the screen-lighting condition is a motion state of motion + reduced motion speed, the second preset time period is often a time period corresponding to reduced motion speed of the electronic device, and so on. The preset value range is typically around 1, for example: 0.8 to 1.2, 0.7 to 1.2, and the like. If the first judgment result is yes, the electronic equipment can be further confirmed to be in the static state.

Also, the screen of the electronic device may be directly controlled to enter the lighting state when the sum of squares is within the preset numerical range, and the screen of the electronic device may be controlled to enter the lighting state in a case where the lighting conditions of the respective screens are satisfied if other screen lighting conditions exist.

The process of determining whether the square sum is within the preset value range may be performed after the matching result in step S102 indicates that the waveform of the acceleration value is matched with the preset waveform, or may be performed simultaneously with the waveform matching, or performed before the waveform matching, which is not limited in the embodiment of the present invention.

Second, the determining whether to control the screen of the electronic device to enter a lighting state further includes:

if the lighting operation exists, judging whether a rotation angle value of the electronic equipment relative to the user direction is larger than a preset angle value or not, and obtaining a second judgment result, wherein the rotation angle value is the rotation angle value of the screen relative to the user direction from the time point of the lighting operation to the current time point;

For example, the third preset time period is, for example: 2s, 3s, 5s, etc., wherein, in general, the user does not view the screen of the electronic device twice at the same time for a very short period of time, so if there has been an operation of lighting the screen by means of waveform matching within a third preset period of time, there is a possibility that an erroneous operation (for example, the user places the hand on the table) is made even if the waveform of the currently detected acceleration value matches the preset waveform, so to prevent the erroneous operation, a further trigger condition (for example, whether the rotation angle value of the screen with respect to the user direction is larger than the preset angle value) may be set, if the angle value is greater than the preset angle value, it indicates that the user really wants to light the screen of the electronic device, so that the screen of the electronic device is controlled to enter a lighting state, and the preset angle value may be set according to actual requirements, for example: 20 °, 30 °, 40 °, etc. Wherein the rotation angle value with respect to the user direction being greater than the preset angle value means that the screen is turned inward, and the rotation angle value along the X-axis (in accordance with the right-hand rule) is greater than the preset angle value (for example, 30 °).

It is also possible to directly control the screen of the electronic apparatus to enter the lighting state when the second determination result is yes, and to control the screen of the electronic apparatus to enter the lighting state only in a case where each lighting condition is satisfied if there are a plurality of lighting conditions.

In a specific implementation process, whether a user generates a hand-lifting and screen-lighting gesture can be directly determined through a waveform of an acceleration value of the electronic device, and then whether the screen of the electronic device is controlled to enter a lighting state is determined, but in a general situation, when the user generates the hand-lifting and screen-viewing gesture in a static state and the hand-lifting and screen-viewing gesture in a motion state, the motion states of the electronic device are different, so that the motion states of the electronic device meeting the screen-lighting condition can be different motion states based on whether the electronic device is in the motion state. For example: whether the motion amplitude value of the electronic equipment is smaller than a preset amplitude value in a fourth preset time period before the first preset time period can be judged; and if the motion amplitude value is smaller than the preset amplitude value, executing the step of matching the waveform of the acceleration value with a preset waveform.

The fourth preset time period is, for example: 1s, 2s, etc., and the predetermined amplitude values are, for example: 0.01g, 0.02g, etc., wherein whether the motion amplitude value of the electronic device is smaller than a preset amplitude value can be determined by the sum of the absolute values of the differences in acceleration values in the three coordinate axis directions, for example: if the sum of the absolute values of the acceleration value differences is within the preset numerical range, the motion amplitude value is smaller than the preset amplitude value, otherwise, the motion amplitude value is not smaller than the preset amplitude value, and the like. If the motion amplitude value is smaller than the preset amplitude value, it is indicated that the user of the electronic device may be in a stationary state, and in addition, it may be further determined whether the sum of the squares of the three axes is within a preset numerical range (for example, whether the sum is approximately equal to 1), and if the sum is within the preset numerical range, it may be further determined that the user is in the stationary state, in this case, when the user generates a hand-up and screen-viewing gesture, the motion state of the corresponding electronic device is a motion state + stationary motion state, and the waveform of the acceleration value may have an obvious difference when the motion is switched to the stationary state, so it may be accurately determined whether the motion state of the electronic device satisfies the screen-up condition in the manner provided in steps S101 to S103.

If the motion amplitude value is not smaller than the preset amplitude value, it indicates that the user may raise his hand to see the screen in the motion state, in this case, there is no obvious feature in the waveform of the acceleration value because there is no stationary motion, so in order to more accurately determine whether the operation of the user meets the screen-lighting condition, please refer to fig. 4, the following manner may be adopted:

step S401: if the motion amplitude value is not smaller than the preset amplitude value, determining the motion amplitude value of the electronic equipment within a fifth preset time period;

step S402: carrying out smoothing processing on the motion amplitude value to obtain a smoothed motion amplitude value;

step S403: judging whether the change trend of the smoothed motion amplitude value meets a preset change trend or not, and obtaining a third judgment result;

step S404: determining whether to control the screen to enter the lighting state based on the third judgment result; and if the third judgment result is yes, controlling the screen to enter the lighting state.

In step S401, the fifth preset time period is, for example: the fifth preset time period is, for example, a time period consumed by the user for generating the hand-raising and screen-viewing gesture in the motion state: 1s, 2s, 3s, etc. Which may be the same as or different from the first preset time period.

In step S401, a waveform of an acceleration value of the electronic device may be determined first, and then a motion amplitude value of the electronic device may be estimated through a differential operation, where the estimation method is as follows:

A(n)＝|x(n)-x(n-1)|+|y(n)-y(n-1)|+|z(n)-z(n-1)|

………………………………[1]

wherein n represents the current sample point and n-1 represents the last sample point;

a (n) represents the motion amplitude value of the current sample point;

x (n) represents an acceleration value of the X axis of the current sampling point;

x (n-1) represents the acceleration value of the X axis of the last sampling point;

y (n) represents an acceleration value of the Y axis of the current sampling point;

y (n-1) represents the acceleration value of the Y axis of the last sampling point;

z (n) represents an acceleration value of the Z axis of the current sampling point;

z (n-1) represents the acceleration value of the Z axis of the last sampling point.

In step S402, the motion amplitude value may be smoothed by various algorithms, such as: additive smoothing algorithms, interpolation smoothing algorithms, turing smoothing algorithms, and the like. The smoothing process may adopt a long smoothing mode or a short smoothing mode, and the smoothing algorithm is, for example:

s(n)＝α·s(n-1)+(1-α)·A(n),0≤α≤1

………………………………[2]

α represents a smoothing coefficient, and the larger the value α is, the longer the corresponding smoothing duration is;

s (n) represents the smoothing result of the nth sample point;

s (n-1) represents the smoothing result at the n-1 th point.

Since the amplitude of the acceleration value of the electronic device varies greatly during the movement of the user, in order to achieve a good smoothing effect, the movement amplitude value is often smoothed in a long smoothing manner, for example, α -0.975-1-1/40 may be taken as long smoothing (smoothing length is 40 sampling points), in the actual processing, the smoothing length may be 20-100, or 20-1000 sampling points and the like may be taken as long smoothing, based on the difference in the number of sampling points, the obtained smoothing coefficients are also different, and the embodiment of the present invention is not limited.

In step S403, if the user generates the hand-raising and screen-lighting gesture while in the motion state, the motion amplitude value of the user usually rises to a certain amplitude and then remains stable (corresponding to the motion process of the user), and then continues to fall to the first amplitude and then remains stable (corresponding to the hand-raising process of the user), so that the fifth preset time period includes, for example: the first sub-period and a second sub-period after the first sub-period, the preset trend of change includes: a trend of increasing in the first sub-period and decreasing in the second sub-period.

The first sub-time period is a time period corresponding to user movement and no hand raising, and the user is in a movement state in the time period, so that the movement amplitude value of the electronic equipment is in a growth state; the second sub-time period is a time period corresponding to the user movement and the hand-up viewing screen, and in this case, the movement amplitude of the user tends to be reduced, so that the movement amplitude value of the electronic device is in a reduced state.

In the specific implementation process, whether the motion amplitude value meets the preset variation trend can be determined in various ways, and two of them are listed below for description, but, of course, in the specific implementation process, the method is not limited to the following two cases.

FIG. 5 shows a waveform of an acceleration value of a user in a running state at a portion shown in an ellipse 50, a waveform of an acceleration value of an electronic device when the user lifts up and looks at a screen after the user is in the running state at a portion shown in an ellipse 51, and a waveform 52 of a motion amplitude value after smoothing processing, wherein whether a trend of increasing first and decreasing second exists at a portion of the waveform 52 in the fifth preset time period may be judged, and if so, it is determined that the variation of the motion amplitude value satisfies the preset variation trend.

The determination method ② includes obtaining a preset number of sample points (e.g., 10, 12, etc.) from the motion amplitude value of the electronic device, then determining the sample point with the highest value (e.g., 7 th sample point) from the sample points, determining whether the motion amplitude values of other sample points before the sample point are all smaller than the motion amplitude value of the sample point, and determining whether the motion amplitude values of other sample points after the sample point are all larger than the motion amplitude value of the sample point, and if the determination result is yes, determining that the variation of the motion amplitude value satisfies a preset variation trend.

In step S404, if the third determination result is yes, it is described that the motion state of the electronic device satisfies the lighting condition, if no other lighting condition exists, the screen of the electronic device may be directly controlled to enter the lighting state, and if other lighting condition exists, the screen of the electronic device is controlled to enter the lighting state only if the other lighting condition is also satisfied.

As an alternative embodiment, the determining whether to control the screen to enter the lighting state, referring to fig. 6, further includes:

step S601: acquiring a rotation angle value of the electronic equipment relative to a preset reference object;

step S602: judging whether the rotation angle value is within a first preset angle range or not to obtain a fourth judgment result;

step S603: determining whether to control the screen to enter the lighting state based on the fourth judgment result; and if the fourth judgment result is yes, controlling the screen to enter the lighting state.

In step S601, the rotation angle values may include rotation angle values corresponding to coordinate axis directions, and the preset reference objects may also be different based on different corresponding coordinate axis directions, for example: if the rotation angle value is the rotation angle value in the X-axis direction, the preset reference object is, for example, a plane formed by the Y-axis and the Z-axis, and the rotation angle in the X-axis direction is a pitch angle theta; if the rotation angle value is the rotation angle value in the Y-axis direction, the preset reference object is, for example, a plane formed by an X-axis and a Z-axis, and the rotation angle in the Y-axis direction is a roll angle; if the rotation angle value is a rotation angle value in the Z-axis direction, the preset reference object is, for example: the plane formed by the X axis and the Y axis, etc.

In the specific implementation process, the manner of determining the rotation angle value is different based on the difference of the motion state of the user, and two of them are listed below for description, and of course, in the specific implementation process, the method is not limited to the following two cases.

Firstly, if the motion amplitude value of the electronic equipment is smaller than the preset amplitude value, acquiring acceleration values of the electronic equipment in three coordinate axis directions within a sixth preset time period; and determining the rotation angle value of the screen based on the acceleration values in the three coordinate axis directions. In the case that the sixth preset time period is generally the time period (for example, 0.01s, 0.02s, etc.) corresponding to the first preset time period or the time period corresponding to the part of the fifth preset time period that is close to the end, if the motion amplitude value is smaller than the preset amplitude value, the difference between the acceleration value before and after smoothing is not large, and in this case, the rotation angle value is determined directly through the acceleration value, so that the processing load of the electronic device can be reduced.

Secondly, if the motion amplitude value of the electronic equipment is not smaller than the preset amplitude value, acquiring acceleration values of the electronic equipment in three coordinate axis directions within a sixth preset time period; carrying out smoothing processing on the acceleration value to obtain the smoothed acceleration value; and determining the rotation angle value based on the acceleration value after the smoothing processing.

For example, when the motion amplitude value of the electronic device is not less than the preset amplitude value, the change amplitude is large, so that the rotation angle value of the electronic device cannot be directly determined through the acceleration value. The acceleration values in the three coordinate axis directions can be smoothed in various ways, and the smoothing algorithm is introduced above and thus is not described herein again. The acceleration values in the three coordinate axis directions can be smoothed in a long smoothing mode or a short smoothing mode, and the smoothing formula is similar to the formula [2 ].

As an alternative example, the respective acceleration values may be smoothed by short smoothing, and then the rotation angle value of the screen may be determined based on the smoothed acceleration values, for example, α ≈ 0.83 ≈ 1-1/6, and smoothing of about 6 points (the smoothing length is six sampling points) may be taken, and in the actual processing, 2-10 sampling points or the like with the smoothing length may be considered as the short smoothing.

In step S602, the purpose of determining whether the rotation angle value is within the first preset angle range is to determine whether there is a screen viewing action after the user has raised his/her hand, and if so, further indicating that the user needs to view the screen.

In general, consider that the user is in a standing or supine position, etc., if the rotation angle values include: the angle value of the roll angle, the first preset angle range corresponding to the roll angle includes: -45 ° to 45 °; if the angle of rotation value includes: if the motion amplitude value is smaller than a preset amplitude value (for example, the user is in a stationary state), the first preset angle range corresponding to the pitch angle includes: -15 to 150 °; if the motion amplitude value is not smaller than the preset angle value (for example, the user is in a motion state), the first preset angle range corresponding to the pitch angle includes: -15 to 90.

In step S603, if the rotation angle value is within the first preset angle range, it indicates that there may be an action of viewing the screen by the user, and in this case, it may be determined that the rotation angle value meets the screen-lighting condition, and the screen of the electronic device may be directly controlled to enter the lighting state, or the screen of the electronic device may be controlled to enter the lighting state under the condition that other screen-lighting conditions are met; and if the rotation angle value is not in the first preset angle range, the rotation angle value is not in accordance with the screen lighting condition, and the screen of the electronic equipment can not be controlled to enter the lighting state.

As an alternative embodiment, the method further comprises: after the electronic equipment is controlled to enter the lighting state, acquiring a rotation angle value of the electronic equipment relative to a preset reference object; judging whether the rotation angle value is within a second preset angle range or not; and if the screen is positioned in the second preset angle range, controlling the screen to enter a turning-off state.

In a specific implementation process, after controlling the screen of the electronic device to enter the on state, if the electronic device is used up, the user may control the screen of the electronic device to enter the off state in order to save power. The second preset angle value is often other angle values different from the first preset angle value, and if the rotation angle value of the electronic device is not within the first preset angle range, it indicates that the user does not watch the screen, so that the screen of the electronic device can be controlled to enter a turning-off state.

Wherein, in general, if the rotation angle value includes: the angle value of the roll angle, the second preset angle range corresponding to the roll angle includes: gamma >60 DEG or gamma < -60 DEG; if the angle of rotation value includes: the angle value of the pitch angle, and the corresponding second preset angle range thereof includes: theta < -30 deg., theta >165 deg., and so on. Because the second preset angle range is not completely overlapped with other angle ranges outside the first preset angle range, the robustness of the algorithm can be ensured, and the screen is prevented from being frequently controlled to be switched between the on state and the off state.
