Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
In order to achieve the purpose that a person works when using the active pen product, the person enters a low-power consumption mode when not using the active pen product, the main stream is to detect acceleration by adopting an accelerometer, when the acceleration is larger than a certain threshold value, the person is regarded as waking up the active pen to start working when using the active pen, and when the acceleration is continuously lower than the certain threshold value and is continuously for a period of time, the person is regarded as not using the active pen, and the active pen enters the low-power consumption mode. The method for judging whether the person is using the active pen by detecting whether the acceleration is larger than a certain threshold value has low accuracy, and it is very difficult to actually judge that the intention of the person is just the acceleration.
For example, in the patent CN111142958A, "active pen sleep wake-up method, apparatus, device and readable storage medium", it is disclosed to use acceleration and/or nib pressure to determine the switch time of the active pen from the sleep mode of turning off the screen signal detection module to the wake-up mode of turning on the screen signal detection module, and then use the screen signal to determine the switch time of the active pen from the wake-up mode to the working mode. Therefore, the existing determination mode of the using intention of the active pen is still inaccurate.
In order to solve the above problems, the present invention provides a method for judging the usage of an active pen, in which after the active pen is started, a user's no-usage intention is judged by a screen end signal, a specific acceleration and a pen tip pressure together, so as to enter a first state, so that the situation of no-usage intention can be accurately judged; the use intention is further judged according to the acceleration in the first state, and the screen signal detection function is started within a period of time after the specific acceleration is detected, so that the use intention of the active pen can be accurately and not missed at any moment of a user, and the accuracy of the use intention of the active pen is improved; if the screen signal is not detected in the time period, the acceleration and the nib pressure are not concerned in a future period, so that the power consumption can be saved as much as possible on the premise of normal functions, the situation that the active pen is placed in a knapsack scene, the acceleration is continuously detected due to continuous transmission of the external shaking of walking to the active pen, and unnecessary power consumption is generated is reasonably avoided, and the judgment accuracy of the use intention of the active pen is comprehensively improved.

Based on the hardware structure, the embodiment of the method for judging the use of the active pen is provided.
Referring to fig. 2, fig. 2 is a flowchart of a first embodiment of an active pen usage discriminating method according to the present invention. The active pen use discriminating method comprises the following steps:
step S10, judging whether the active pen has specific acceleration or not when the active pen is in a first state of closing a screen end signal detection module, wherein the first state is a state that the active pen continuously does not detect nib pressure, a screen end signal sent by screen equipment and the specific acceleration in a preset first duration;
in this embodiment, the invention is applied to an active pen, i.e., an active capacitive pen. The capacitive pen is made of conductive materials and used for touch capacitive screens to complete man-machine conversation, and is an auxiliary device for simulating human bodies (usually fingers) to complete man-machine conversation by using conductive materials. The on-screen signal detection module is used for receiving an external signal and analyzing whether the external signal is a signal sent by the on-screen device. If the active pen is continuously started under the condition that the user does not use the active pen for a long time, the power consumption of the active pen can be greatly increased, so that the user needs to accurately judge the use intention of the active pen, the active pen is started only when necessary, and the active pen is closed in the rest time to save the power consumption. The specific acceleration refers to that the acceleration of the active pen exceeds a preset acceleration threshold value, and the threshold value can be flexibly set according to actual conditions. The first state refers to a state in which it is preliminarily determined that the user does not have a high intention to use the active pen, and in the first state, the screen end signal detection module is turned off by default, but the capability of detecting a specific acceleration and a pen point pressure is still provided (the energy consumption of detecting the two items is not high). The preset first time length refers to a time length for fixedly starting the screen end signal detection module after the active pen is started, and the time length can be flexibly set according to actual conditions, but is not suitable to be set too long, and the embodiment is not particularly limited.
Because the user can have one or more of three conditions of pen point pressure, screen signal and acceleration change when using the active pen to write, but can have one or more of the three conditions for various reasons when not using the active pen to write, but the three conditions do not exist simultaneously, when the active pen can not detect any one of the three conditions for a long time, the user can judge that the user does not have the intention to use at the moment, and the signal detection module can be closed first to enter the first state, so that the energy consumption is saved as much as possible. For example, the current scenario is: the user needs to use the active pen but leave the active pen temporarily out of the screen range. At this time, although there is no screen end signal and no nib pressure, there may be acceleration variation, if the user's intention to use in this scene is judged only by the screen end signal and nib pressure, that is, the signal detection module is turned off only by the screen end signal and nib pressure not being detected, misjudgment will occur, so that the user temporarily leaves the screen range of the active pen, and returns the active pen to the screen end for writing.
And after the active pen enters the first state, although the intention judgment can not be preferentially carried out according to the screen end signal, the pilot judgment can be carried out by utilizing the acceleration. The active pen further detects whether the acceleration of the active pen is greater than a preset acceleration threshold in the first state.
Step S20, if yes, continuously starting the screen end signal detection module within a preset second duration after the specific acceleration is detected;
in this embodiment, if it is detected whether the acceleration of the active pen in the first state is greater than the preset acceleration threshold, a wake-up is triggered and signal reception is briefly turned on. The preset second duration refers to a duration for one wake-up, which is generally set to be shorter than the preset first duration, and specifically can be flexibly set according to practical situations.
The short-time wake-up mode needs to be set under the condition of no screen signal and acceleration, so that even if the active pen is in the condition of no screen signal and acceleration, the user still has the use intention of the active pen, for example, the user takes the active pen from elsewhere and prepares to write by using the active pen, at the moment, the active pen does not reach the screen range and has no nib pressure, but the user has the use intention, and therefore, the signal detection can be started briefly at the moment to detect whether the screen signal exists or not.
The condition of using the nib pressure is not considered for judgment because in actual cases there is also such a scene: the user does not use the active pen, but rests it in the barrel. In this scenario, there is no tip signal and acceleration, but there is tip pressure, i.e., there is no user intention in the case of only tip pressure in three conditions, so the signal detection cannot be turned on based on the presence of only tip pressure.
Step S30, judging whether the active pen detects the screen end signal within the preset second duration based on the screen end signal detection module;
and S40, if the screen end signal is not detected, closing the screen end signal detection module, and switching to an anti-interference mode which needs to be continuously preset for a third time, wherein the specific acceleration and the nib pressure are disregarded by the active pen in the anti-interference mode.
In this embodiment, the active pen determines whether the screen end signal can be detected within a preset second duration based on the screen end signal detection module that is currently temporarily turned on. For example, if the second duration is preset to be 1 minute, the active pen triggers a short-time wake-up at nine am, and then it is determined whether a screen end signal is received within one minute from nine am to nine am. If the screen end signal is not received, the user may just replace the active pen for placement in a place, or the active pen is placed in a knapsack at the moment, because the acceleration and the nib pressure are generated when the user walks, and no writing intention exists, the short-time wake-up of this time is finished, the screen end signal detection module is closed at the end of nine points of zero and one minute, and in order to prevent frequent interference shake under the knapsack situation, the anti-interference mode is performed for a period of time after nine points of zero and one minute. In this mode, the active pen is not affected by acceleration and nib pressure, i.e., acceleration and/or nib pressure are detected, nor is signal detection turned on. The preset third period of time may be flexibly set according to practical situations, but is not set too short in consideration of saving power consumption, and is generally set longer than the preset second period of time.
At the end of the primary tamper mode, the active pen may enter the normal first state again, and the process returns to step S10 to continue observing the specific acceleration.
The embodiment provides a method for judging the use of an active pen, which judges that a user does not use an intention through a screen end signal, specific acceleration and nib pressure together after the active pen is started so as to enter a first state, so that the situation of no use intention can be accurately judged; the use intention is further judged according to the acceleration in the first state, and the screen signal detection function is started within a period of time after the specific acceleration is detected, so that the use intention of the active pen can be accurately and not missed at any moment of a user, and the accuracy of the use intention of the active pen is improved; if the screen signal is not detected in the time period, the acceleration and the nib pressure are not concerned in a future period, so that the power consumption can be saved as much as possible on the premise of normal functions, the situation that the acceleration is continuously detected due to continuous transmission of the external shaking of walking to the active pen and unnecessary power consumption is generated is reasonably avoided, the judgment accuracy of the use intention of the active pen is comprehensively improved, and the technical problem of how to improve the accuracy of judging that the user has the use intention of the active pen is solved.
Further, based on the first embodiment shown in fig. 2, a second embodiment of the active pen use discriminating method of the present invention is proposed. In this embodiment, after step S30, the method further includes:
and step A1, if the screen end signal is detected, switching the active pen to a second state of opening the screen end signal detection module by default.
In this embodiment, if the active pen detects the screen end signal in any short-time wake-up mode, it is indicated that the situation that the active pen is placed in the backpack and is disturbed can be eliminated, the user currently picks up the active pen and places the active pen in the screen range, and when the current short-time wake-up mode is released, the active pen is switched to a second state of continuously starting the screen end signal detection module, that is, a normal writing state, so that the user can write by using the active pen normally, and the writing experience of the user cannot be affected.
Further, after step A1, the method further includes:
a2, judging whether the specific acceleration, the nib pressure and/or the screen end signal are detected within a preset fourth time period after the active pen enters the second state;
and step A3, if the active pen detects the screen end signal within the preset fourth time period, but does not detect the nib pressure and the specific acceleration, the second state is maintained.
In this embodiment, the preset fourth duration is a duration for the active pen to fixedly turn on the screen end signal detection module after entering the second state, which is generally set to be longer than the preset second duration, and may be the same as the preset first duration. The following situations may exist due to actual use: the user uses the active pen but hangs it from the on-screen stagnant thinking problem. That is, in the second state, no nib pressure, no specific acceleration, but a screen signal occurs. At this time, the user still has the intention of using, so the signal detection module can not be turned off, but is kept on.
The embodiment is provided with the following steps: in the second state, when the screen signal is detected but the pressure and acceleration change of the pen point are not detected, the rule of using the active pen is still considered, so that the misjudgment condition of using the active pen but suspending the pen on the screen to stop thinking can be avoided, and the judgment accuracy of the using intention is improved.
In addition, as an implementation manner, the preset fifth time period may be continuously started after the preset fourth time period, and if the screen signal is not detected within the preset fifth time period after the preset fifth time period is continuously started, the first state may be switched to so as to save energy consumption.
This processing mode is set because there may be the following cases in actual use: after the user uses the active pen for a period of time, the user stops the active pen, but stands on the screen in the working state. That is, the condition that the pen point pressure is absent for a long time and the pen point pressure is absent after the pen point pressure enters the second state, but the pen point pressure is absent is provided, so that if the acceleration or the pen point pressure cannot be detected within a period of time after the pen point pressure enters the second state, only the pen point signal is provided, the signal detection needs to be kept for a period of time to be started, and if the acceleration or the pen point pressure is still not detected after the time, the fact that the user temporarily does not use the pen point pressure is judged at the moment, and the signal detection module can be temporarily closed to be switched to the first state for saving energy consumption, and then is opened after the acceleration is detected later. If the scene is not identified, the signal detection module is always started under the condition that only the screen signal exists, so that unnecessary energy consumption of the active pen can be increased.
The embodiment is provided with the following steps: when the screen signal is detected but the pressure and acceleration change of the pen point are not detected in the first state, if the rule that the active pen is not used is considered to be long, the misjudgment condition that the active pen is used to be placed on the screen in the working state can be avoided, and the judgment accuracy of the using intention is improved.
Further, after step A1, the method further includes:
and step A4, if the active pen does not detect the screen end signal and the pen point pressure within the preset fourth time period, but detects the specific acceleration, the screen end signal detection module is kept on.
In this embodiment, since during actual use, it may happen that the user needs to use the active pen, but the active pen is temporarily moved out of the screen range. Although the screen end signal is detected previously, the screen end signal is not detected when the pen leaves, the pen point pressure is not detected, and acceleration change possibly exists, so that the user still keeps the use intention under the situation, and the screen end signal detection module needs to be kept on to ensure the normal writing function of the active pen. If the screen end signal detection module is closed at this time, misjudgment occurs, so that the user temporarily leaves the screen range of the active pen and returns the active pen to the screen end for writing, and the writing experience is greatly influenced because the active pen is closed for receiving signals at this time and cannot write normally.
The embodiment is provided with the following steps: when the screen signal is in the second state, if the acceleration exists, the rule of using the active pen is continuously maintained even if the screen signal is not detected, so that the misjudgment condition that the active pen is used but the pen temporarily leaves the screen range can be avoided, and the judgment accuracy of the using intention is improved.
Further, based on the above-described first embodiment, a third embodiment of the active pen use discriminating method of the present invention is proposed. In this embodiment, after step S10, the method further includes:
step B1, if not, judging whether the active pen detects the nib pressure meeting the preset pressure condition;
and step B2, if the nib pressure meeting the preset pressure condition is detected, closing the screen end signal detection module to switch to the first state.
In this embodiment, after the active pen enters the first state, if the specific acceleration is not detected for a long time, even if only the stable pen tip pressure is detected, the active pen can be disregarded, and the specific acceleration is continuously detected while maintaining the first state. There may thus be a scenario: the user does not use the active pen, but rests it in the barrel. In this scenario, there is no tip signal and acceleration, but there is a stable tip pressure, i.e. no user intention to use if there is only tip pressure in the three conditions in the first state, so the signal detection cannot be turned on based on the presence of only tip pressure.
Further, the step of determining in the step B1 whether the active pen detects the nib pressure satisfying the preset pressure condition includes:
step B11, judging whether the active pen detects the nib pressure with the change amplitude not exceeding a preset amplitude threshold;
step B12, if yes, judging that the active pen detects the pen point pressure meeting the preset pressure condition;
and step B13, if not, judging that the active pen does not detect the nib pressure meeting the preset pressure condition.
In this embodiment, the nib pressure satisfying the preset pressure condition refers to a stable nib pressure, and specifically, whether the nib pressure is stable or not can be determined by a preset amplitude threshold. If the variation amplitude between the nib pressures acquired at adjacent sampling moments does not exceed the preset amplitude threshold, the nib pressure is indicated to be stable, otherwise, the nib pressure is not stable. The preset amplitude threshold is generally set to be zero or a value close to zero, and can be flexibly set according to actual conditions.
The embodiment is provided with the following steps: when the screen signal and the acceleration change cannot be detected for a period of time in the first state, if the pen point has pressure but keeps stable, the rule of 'not using an active pen' is considered, so that the misjudgment of the 'pen container situation' can be avoided, and the judgment accuracy of the using intention is improved.
Further, before step S10, the method further includes:
step S01, continuously starting the screen end signal detection module within a preset first time period after the active pen is started, and judging whether the screen end signal, specific acceleration and/or pen point pressure are detected by the active pen within the preset first time period;
and step S02, if the screen end signal, the specific acceleration and the nib pressure are not detected, closing the screen end signal detection module to enter the first state.
In this embodiment, when the user uses the active pen to write, the active pen needs to be started first, so that the possibility that the user has a use intention at the start time of the active pen is high, the start signal detection needs to be fixed within a period of time after the start, and the user may have one or more of three conditions including pen point pressure, screen signal and acceleration change during the use of the active pen, but when the user does not use the active pen to write, the three conditions may have one or more of the three conditions for various reasons, but the three conditions do not exist simultaneously, so that when the active pen cannot detect any one of the three conditions for a continuous period of time, the user can judge that the user does not have the use intention at the moment, and the signal detection module can be turned off first to enter the first state, so that energy consumption is saved as much as possible. For example, the current scenario is: the user needs to use the active pen but leave the active pen temporarily out of the screen range. At this time, although there is no screen end signal and no nib pressure, there may be acceleration variation, if the user's intention to use in this scene is judged only by the screen end signal and nib pressure, that is, the signal detection module is turned off only by the screen end signal and nib pressure not being detected, misjudgment will occur, so that the user temporarily leaves the screen range of the active pen, and returns the active pen to the screen end for writing. Similarly, if the specific acceleration, the pen point pressure and the screen signal are detected within the first time period, the user is indicated to have the use intention, and the second state is kept.
The embodiment is provided with the following steps: the rule of "not using active pen" is considered when the screen signal is not detected and acceleration and pressure change are not generated for a period of time, so that the situation that the active pen is used but the pen temporarily leaves the screen range and is misjudged as "no use intention" can be avoided, the situation that the active pen is not used and is stationary on a desktop "can be identified, and the judgment accuracy of the use intention is improved.
