Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The current active pen product adopts an accelerometer to detect acceleration in order to achieve the purpose that a person works when the person uses the active pen and enters a low power consumption mode when the person does not use the active pen, the active pen is considered to be awakened to start working when the acceleration is larger than a certain threshold, and the active pen enters the low power consumption mode when the acceleration is continuously lower than the certain threshold and is continuously used for a period of time. The method for judging whether the person uses the active pen by detecting whether the acceleration is greater than a certain threshold value has low accuracy, and it is difficult to actually judge the intention of the person only by the acceleration.
For example, CN111142958A, "active pen sleep wake-up method, apparatus, device, and readable storage medium" discloses that acceleration and/or nib pressure are used to determine the switching timing 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 the screen signal is used to determine the switching timing of the active pen from the wake-up mode to the working mode. Therefore, the existing method for determining the use intention of the active pen is still not accurate enough.
In order to solve the problems, the invention provides a method for judging the use of an active pen, namely, the active pen firstly judges that a user has no use intention through a screen end signal, specific acceleration and pen point pressure after being started so as to enter a first state, so that the condition 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 at any moment of the user can be accurately and not omitted, and the accuracy of the use intention of the active pen is improved; if the screen signal is not detected in the time period, acceleration and pen point pressure are not concerned any more in a future time period, so that power consumption can be saved as far as possible on the premise of normal functions, the situation that the active pen is placed in a backpack scene, and unnecessary power consumption is caused due to the fact that the external shaking of walking is continuously transmitted to the active pen and the acceleration is continuously detected, is reasonably avoided, and therefore the accuracy of judgment 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 illustrating a method for determining the use of an active pen according to a first embodiment of the present invention. The method for judging the use of the active pen comprises the following steps:
step S10, when the active pen is in a first state of closing the screen end signal detection module, judging whether the active pen has a specific acceleration, wherein the first state is a state that the active pen enters after pen point pressure, a screen end signal sent by screen equipment and the specific acceleration are continuously not detected within a preset first time length;
in this embodiment, the invention is applied to an active pen, which is an active capacitive pen. The capacitive pen is a pen which is made of a conductor material, has a conductive characteristic and is used for touch control of a capacitive screen to complete man-machine conversation operation, and is an auxiliary device for completing man-machine conversation by simulating a human body (usually fingers) through the conductor material. The screen end signal detection module is used for receiving an external signal and analyzing whether the external signal is a signal sent by the screen end equipment. 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 is greatly increased, so that the use intention of the user for the active pen needs to be accurately judged, 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 the acceleration of the active pen exceeding a preset acceleration threshold, and the threshold can be flexibly set according to actual conditions. The first state refers to a state of preliminarily judging that the user has no higher intention of using the active pen, and in the first state, the screen end signal detection module is closed by default, but the capability of detecting specific acceleration and pen point pressure is still provided (the energy consumption for detecting the two items is not high). The preset first duration refers to the duration that the screen end signal detection module needs to be fixedly started after the active pen is started, and specifically, the duration can be flexibly set according to actual conditions, but the duration cannot be set too long, and the embodiment is not specifically limited.
When the active pen is used for writing, one or more of three conditions of pen point pressure, screen signals and acceleration change may exist, and when the active pen is not used for writing, the three conditions may also exist for various reasons, but the three conditions do not exist simultaneously, so that when the active pen does not detect any of the three conditions for a certain period of time, the active pen can judge that the user does not have the intention to use at the moment, and the signal detection module can be turned off to enter the first state first, 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. At this time, although there is no screen end signal and no pen point pressure, there may be acceleration change, if the user's intention is judged only by the screen end signal and the pen point pressure, that is, the signal detection module is closed only by not detecting the screen end signal and the pen point pressure, an erroneous judgment will occur, which results in that the user temporarily leaves the screen range of the active pen and takes it back to the screen end for writing, because the active pen has closed the signal reception and can not write normally, therefore, only when the active pen does not meet the three conditions continuously for a period of time, the first state can be entered.
After the active pen enters the first state, although the intention judgment cannot be performed preferentially according to the screen end signal, the pilot judgment can be performed 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, the screen end signal detection module is continuously started within a preset second time length 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 may be triggered and the signal reception may be turned on briefly. The preset second time length refers to the duration of one-time awakening, and the duration is usually set to be shorter than the preset first time length, and can be flexibly set according to actual conditions.
The reason why the short-time wake-up mode needs to be set under the condition of no screen signal but acceleration is that even if there is no screen end signal but acceleration, the user still may have an intention to use the active pen, for example, the user picks up the active pen from other places to prepare to use the active pen for writing, and at this time, the active pen does not reach the screen range and has no pressure of the pen point, but the user has an intention to use, so that signal detection can be turned on briefly at this time to detect whether there is a screen end signal.
The reason why the judgment is made without considering the condition of using the pen tip pressure is that in actual situations, there is a scene: the user does not use the active pen, but rests it in the pen container. In this scenario, although there is no screen edge signal and acceleration, there is pen tip pressure, i.e., there is only pen tip pressure among the three conditions, and the user has no intention to use, and therefore, signal detection cannot be turned on based on the presence of only pen tip pressure.
Step S30, judging whether the active pen detects the screen end signal within the preset second time length based on the screen end signal detection module;
and step S40, if the screen end signal is not detected, closing the screen end signal detection module, and switching to an anti-interference mode needing to continuously preset a third time at a single time, wherein the active pen does not look at the specific acceleration and the pen point pressure in the anti-interference mode.
In this embodiment, the active pen determines whether the screen end signal can be detected within a preset second time period based on the currently temporarily turned on screen end signal detection module. For example, the preset second time duration is 1 minute, and the active pen is triggered to wake up once at nine am for a short time, and then it is determined whether the screen end signal is received within zero minutes from nine am to nine am. If the screen end signal is not received, the situation shows that the user may place the active pen only in one place, or the active pen is placed in the backpack at the moment, and the short-time awakening is finished because the acceleration and the pen point pressure are generated due to the walking of people and no writing intention exists, the screen end signal detection module is closed when nine points are finished and one zero point is finished, and in order to prevent frequent interference and jitter under the backpack situation, the repentance is performed for a period of time at nine points and one zero point. In this mode, the active pen is not affected by acceleration and tip pressure, i.e. neither acceleration and/or tip pressure is detected, nor signal detection is enabled. The preset third duration can be flexibly set according to actual conditions, but is considered in terms of saving power consumption, is not suitable to be set to be too short, and is generally set to be longer than the preset second duration.
At the end of the one-time tamper-proof mode, the active pen may again enter the normal first state, and also return to step S10 to continue to observe the specific acceleration.
The embodiment provides an active pen use judging method, which is characterized in that after an active pen is started, a screen end signal, specific acceleration and pen point pressure are firstly used for jointly judging that a user has no use intention so as to enter a first state, so that the condition 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 at any moment of the user can be accurately and not omitted, and the accuracy of the use intention of the active pen is improved; if no screen signal is detected in the time period, acceleration and pen point pressure are not concerned any more in a future time period, so that power consumption can be saved as far as possible on the premise of normal functions, the situation that the active pen is placed in a backpack scene, and unnecessary power consumption is caused due to the fact that the external shaking of walking is continuously transmitted to the active pen and the acceleration is continuously detected 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 the use intention of the active pen of a user is solved.
Further, based on the first embodiment shown in fig. 2, a second embodiment of the active pen usage determination method of the present invention is provided. In this embodiment, after step S30, the method further includes:
step A1, if the screen end signal is detected, the active pen is switched to a second state of default opening of the screen end signal detection module.
In this embodiment, if the active pen detects the screen end signal in any one of the short-time wake-up modes, it indicates that the active pen can be excluded from being placed in the backpack and interfered, and the user has currently picked up the active pen and placed in the screen range, and when the current short-time wake-up mode is released, the active pen is switched to the second state of continuously opening the screen end signal detection module, that is, the normal writing state, so that the user normally uses the active pen to write, and the writing experience of the user cannot be influenced.
Further, after the step a1, the method further includes:
step A2, judging whether the specific acceleration, the pen point pressure and/or the screen end signal are detected within a preset fourth time after the active pen enters the second state;
step a3, if the active pen detects the screen end signal within the preset fourth time period, but does not detect the pen tip pressure and the specific acceleration, the second state is maintained.
In this embodiment, the preset fourth duration is a duration for fixedly turning on the screen end signal detection module after the active pen enters the second state, and is usually set to be longer than the preset second duration, which may be the same as the preset first duration. The following may occur due to actual use: the user uses the active pen, but hovers it over the screen to think the problem stagnant. That is, in the second state, the case where there is no pen tip pressure, no specific acceleration, but a screen signal occurs. At this time, the user still has the intention of use, so the signal detection module cannot be turned off, but is kept on.
The embodiment comprises the following steps: when the screen signal is detected but the pen point pressure and acceleration change cannot be detected in the second state, 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 use intention is improved.
In addition, as an implementation manner, the preset fifth duration may be continuously turned on after the preset fourth duration is preset, and if the screen signal is not detected within the time of continuously turning on the preset fifth duration, the state may be switched to the first state to save energy consumption.
This processing manner is provided because the following may occur in actual use: after using the active pen for a period of time, the user stops not using the active pen, but stands still on the screen in the working state. That is, after entering the second state, a long-time no-nib pressure and no acceleration may occur, but there is a screen end signal, so if acceleration or nib pressure is not detected within a period of time after entering the second state, only a screen signal is required, the signal detection needs to be kept on for a period of time, and if acceleration or nib pressure is not detected after a period of time, it is determined that the user has no intention to use at this time. If the scene is not identified, the signal detection module is always started under the condition that only the screen signal exists, and unnecessary energy consumption of the active pen is increased.
The embodiment comprises the following steps: when the screen signal is detected but the pen point pressure and acceleration change cannot be detected in the first state, if the rule lasts for a long time, the active pen is not used, so that the misjudgment condition that the active pen is used and is still on the screen in the working state can be avoided, and the judgment accuracy of the use intention is improved.
Further, after the step a1, the method further includes:
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, keeping the screen end signal detection module on.
In this embodiment, it may happen that the user needs to use the active pen during actual use, but the active pen is temporarily moved out of the screen. Although the screen end signal is detected before, no screen end signal and no pen point pressure exist when the pen leaves, and acceleration change may exist, so that the user still keeps the use intention under the situation and needs to keep the screen end signal detection module to be started to ensure the normal writing function of the active pen. If the screen end signal detection module is closed at the moment, misjudgment can occur, so that the user can temporarily leave the screen range of the active pen and take the active pen back to the screen end for writing, and the writing experience is greatly influenced due to the fact that the active pen is closed and the signal is received, and the situation that normal writing cannot be performed is achieved.
The embodiment comprises the following steps: when the current state is in the second state, if acceleration exists, the rule of 'using the active pen' state is continuously kept even if no screen signal is detected, so that the misjudgment condition that the pen leaves the screen range temporarily when the active pen is used can be avoided, and the judgment accuracy of the use intention is improved.
Further, based on the first embodiment described above, a third embodiment of the active pen use determination 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 pen point pressure meeting a preset pressure condition;
and step B2, if the pen point pressure meeting the preset pressure condition is detected, closing the screen end signal detection module to switch to the first state.
In this embodiment, if the active pen does not detect the specific acceleration for a long time after entering the first state, even if only the stable pen tip pressure is detected, the pen tip pressure can be ignored, the first state is maintained, and the detection of the specific acceleration is continued. There may therefore be a scenario: the user does not use the active pen, but rests it in the pen container. In this scenario, although there is no screen edge signal and no acceleration, there is a stable pen tip pressure, that is, there is no intention of the user in the case where only the pen tip pressure is present among the three conditions in the first state, and therefore, the signal detection cannot be turned on based on the presence of only the pen tip pressure.
Further, the step of determining whether the active pen detects the pen tip pressure satisfying the preset pressure condition in step B1 includes:
step B11, judging whether the active pen detects pen point pressure with a variation amplitude not exceeding a preset amplitude threshold value;
step B12, if yes, judging that the active pen detects pen point pressure meeting a preset pressure condition;
and step B13, if not, judging that the active pen does not detect the pen point pressure meeting the preset pressure condition.
In the present embodiment, the pen tip pressure satisfying the preset pressure condition refers to a stable pen tip pressure, and whether the pen tip pressure is stable or not can be determined by a preset amplitude threshold. If the variation amplitude between the pen point pressures acquired at the adjacent sampling moments does not exceed the preset amplitude threshold value, the pen point pressure is stable, otherwise, the pen point pressure is unstable. The preset amplitude threshold value is generally set to be zero or a value close to zero, and can be flexibly set according to actual conditions.
The embodiment comprises 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 the active pen' is considered, so that the condition of misjudgment of the 'pen container situation' can be avoided, and the judgment accuracy of the use intention is improved.
Further, before step S10, the method further includes:
step S01, the screen end signal detection module is continuously started within a preset first time after the active pen is started, and whether the screen end signal, specific acceleration and/or pen point pressure are detected by the active pen within the preset first time is judged;
step S02, if the screen end signal, the specific acceleration and the pen tip pressure are not detected, the screen end signal detection module is closed to enter the first state.
In this embodiment, since the user needs to start the active pen first when using the active pen to write, the possibility that the user has an intention to use at the time of starting the active pen is very high, the detection of the signal needs to be fixedly started within a period of time after starting the active pen, and the user may have one or more of the three conditions of pen point pressure, screen signal and acceleration change during the use of the active pen, but the three conditions may also 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, so that when the active pen fails to detect any of the three conditions within a period of time, it can be determined that the user does not have the intention to use at this time, and the signal detection module can be turned off first to enter the first state, thereby saving energy consumption 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. At this time, although there is no screen end signal and no pen point pressure, there may be acceleration change, if the user's intention is judged only by the screen end signal and the pen point pressure, that is, the signal detection module is closed only by not detecting the screen end signal and the pen point pressure, an erroneous judgment will occur, which results in that the user temporarily leaves the screen range of the active pen and takes it back to the screen end for writing, because the active pen has closed the signal reception and can not write normally, therefore, only when the active pen does not meet the three conditions continuously for a period of time, the first state can be entered. 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 at this time, and the second state is continuously maintained.
The embodiment comprises the following steps: when the screen signal cannot be detected and no acceleration or pressure change exists for a period of time, the rule of 'not using the active pen' is considered, so that the condition that 'using the active pen but temporarily leaving the screen range' is wrongly judged as 'not using the intention' can be avoided, meanwhile, the situation that 'not using the active pen is still on the desktop' can be identified, and the judgment accuracy of the using intention is improved.
