Description
Technical Field
The disclosure relates to the technical field of air mice, and in particular relates to an air mouse wake-up method, an air mouse wake-up device, electronic equipment and a storage medium.
Background
An air mouse (abbreviated as air mouse) is an input device which can operate a screen cursor like a traditional mouse, but can be directly used without being placed on any plane and swaying in the air.
At present, an air mouse is usually awakened by acquiring a linear acceleration value of the air mouse from a triaxial acceleration sensor, and when a modulus of the linear acceleration value exceeds a preset linear acceleration threshold value, awakening the air mouse.
In practice, the three-axis acceleration sensor collects linear accelerations of the air mouse in three coordinate axis directions under the coordinate system of the three-axis acceleration sensor. Due to the influence of gravity, the components of the gravity acceleration in three axes are added to the data acquired by the triaxial acceleration sensor. In practice, the three-axis acceleration sensor is fixed on the air mouse, so that when the posture of the air mouse changes, the directions of three coordinate axes of the three-axis acceleration sensor are also changed, and the components of gravity acceleration on the three axes are correspondingly changed. The air mouse in different postures swings greatly along the same direction, and the influence of the gravity acceleration on the linear acceleration mode is different. Causing the user to swing with some action in some gestures, the air mouse may be awakened. While in other poses, the user swings with the same action and cannot wake up the air mouse. I.e. different gestures, the same action and inconsistent difficulty in waking up the air mouse.

Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.
Fig. 1 is a flowchart of an air mouse wake-up method provided in an embodiment of the present disclosure, where the embodiment may be suitable for a case of waking up an air mouse from a sleep state, the method may be performed by an air mouse wake-up device, the device may be implemented in a software and/or hardware manner, and the device may be configured in the air mouse. As shown in fig. 1, the method specifically may include:
s110, periodically acquiring angular velocity information of the air mouse.
Alternatively, the angular velocity information of the air mouse may be periodically acquired using an angular velocity sensor integrated in the air mouse. The angular velocity sensor may be a gyroscope or an inertial measurement system, for example.
S120, judging whether the angular velocity information meets a preset wake-up condition or not based on the angular velocity information.
The specific implementation method of this step is various, and optionally, the angular velocity information includes an angular velocity measurement value, and a reference threshold value is set in advance. The specific implementation method of the steps comprises the following steps: and determining the magnitude relation between the angular velocity measurement value and the reference threshold value, and judging whether the angular velocity information meets a preset wake-up condition or not based on the magnitude relation between the angular velocity measurement value and the reference threshold value.
For example, if the angular velocity measurement is greater than the reference threshold, determining that the angular velocity information satisfies a preset wake-up condition; if the angular velocity measured value is smaller than or equal to the reference threshold value, determining that the angular velocity information does not meet the preset wake-up condition.
S130, if the angular velocity information meets the preset awakening condition, awakening the air mouse.
According to the technical scheme, whether the angular velocity information meets the preset awakening condition is judged based on the angular velocity information, if the angular velocity information meets the preset awakening condition, the air mouse is awakened, the essence of the method is to determine whether to awaken the air mouse by means of the angular velocity information instead of the linear acceleration acquired by the triaxial acceleration sensor, the air mouse cannot be interfered by the gravity acceleration in the whole judging process, and the effect that the air mouse swings in the same action when the air mouse is in different postures can be achieved, and the awakening difficulty of the air mouse is consistent.
Studies have shown that in practice, the wake-up action (i.e. the swinging action of the air mouse by the user in order to wake up the air mouse) has two features: the first feature is that the motion is a coherent motion that lasts for a certain time but is shorter in duration; and secondly, the motion has a certain amplitude, and the angular velocity is suddenly changed. Based on this, optionally, setting S120 includes: determining whether the action to be recognized is continuous or not based on the angular velocity information; if the action to be identified is continuous, judging whether the action to be identified is a wake-up action or not; if the action to be identified is a wake-up action, determining whether the angular velocity information meets a preset wake-up condition; otherwise, determining that the angular velocity information does not meet the preset wake-up condition. Wherein, the step of determining whether the action to be identified is continuous is to verify the first feature, and the step of determining whether the action to be identified is a wake-up action is to verify the second feature. This arrangement allows for accurate recognition of the wake-up action.
Fig. 2 is a flowchart of another method for waking up an air mouse according to an embodiment of the present disclosure. Fig. 2 is a specific example of fig. 1. Illustratively, referring to FIG. 1, the method comprises:
s210, periodically acquiring angular velocity information of the air mouse, wherein the angular velocity information comprises angular velocity measurement values and angular velocity measurement value acquisition time.
S220, determining a first time interval between the angular velocity measured value acquisition time and the accumulated time of last updated continuous effective data acquisition.
The valid data is response data of angular velocity information caused by a wake-up operation of a person. For example, since the swing motion for waking up the air mouse needs to have a certain amplitude, a reference threshold value c is preset, and if the angular velocity measurement value a is greater than the reference threshold value c, the angular velocity is considered to be caused by the wake-up motion of the person, and thus the angular velocity measurement value a is valid data. If the angular velocity measurement b is less than or equal to the reference threshold c, it is considered that the angular velocity is not caused by the wake-up action of the person, and therefore the angular velocity measurement c is not valid data.
S230, judging whether the first time interval is larger than a first time interval threshold.
Since the swing motion for waking up the air mouse often lasts for a period of time, the essence of the step is to judge whether the collection time of the angular velocity measured value obtained this time and the accumulated time of last updated continuous collection effective data correspond to the same motion to be identified. If the first time interval is smaller than the first time interval threshold, the time period from the last time of updating the accumulated time of continuously collecting the effective data to the time of collecting the angular velocity measured value obtained this time is indicated that the action to be identified is continuous, and the action to be identified can be considered to correspond to the same action to be identified in the time period. If the first time interval is greater than or equal to the first time interval threshold, the time period from the last time of updating the accumulated time of continuously collecting the effective data to the time of collecting the angular velocity measured value obtained this time is indicated that the action to be identified is discontinuous, and the action to be identified can be considered as not corresponding to the same action to be identified in the time period. This step is to verify the feature one of the wake-up action above.
S240, if the first time interval is smaller than the first time interval threshold, judging whether the angular velocity measured value acquired at this time is effective data.
Since in practice, the swing motion for waking up the air mouse often needs to have a larger swing amplitude, the essence of this step is to determine whether the swing amplitude of the air mouse is large enough or not, and whether it can be recognized that the user is currently making the swing motion for waking up the air mouse.
S250, if the acquired angular velocity measured value is effective data, updating the accumulated times of continuously acquiring the effective data.
S260, if the accumulated number of continuous collection of effective data is larger than the update threshold value, waking up the air mouse.
Since in practice, the swing motion for waking up the air mouse often has a certain duration, the essence of S250 and S260 is to determine whether the duration of the swing motion for waking up the air mouse currently satisfies a certain duration. If the accumulated number of continuous collection of effective data is larger than the update threshold value, namely the duration of the swing action of the current wake-up air mouse reaches a certain duration, determining the action to be identified as the wake-up action, and waking up the air mouse.
S240-S260 verify the wake-up action feature one and feature two above.
The essence of the above technical solution is that the angular velocity information is considered from multiple angles (such as continuity of motion, duration of motion and swing amplitude of motion), and the motion characteristics of the air mouse are determined so as to judge the intention of the holder of the air mouse, which can realize accurate recognition of the wake-up motion.
On the basis of the technical scheme, optionally, the method further comprises: recording the execution time of each step of executing the step of judging whether the acquired angular velocity measured value is valid data or not; at this time, S240 may be replaced with: if the first time interval is smaller than the first time interval threshold, determining the current angular velocity measured value acquisition time and a second time interval of the last execution time of the step of judging whether the current acquired angular velocity measured value is effective data or not; judging whether the second time interval is larger than a second time interval threshold value or not; the second time interval is larger than the time interval of acquiring the angular velocity information of the air mouse twice; if the second time interval is greater than the second time interval threshold, judging whether the acquired angular velocity measured value is effective data or not.
Because in practice, the duration of the swing motion for waking up the air mouse is often much longer than the time interval between the acquisition moments of two adjacent angular velocity sensors, the essence of such arrangement is that only a few times of angular velocity information acquired by the angular velocity sensors is selected as a data basis for judging whether to wake up the air mouse when the air mouse wake-up method provided by the disclosure is executed; instead of taking all angular velocity information acquired by the angular velocity sensor as a data basis for judging whether to wake up the air mouse, the calculation amount of the air mouse wake-up method in the whole execution process can be reduced, and the power consumption is reduced.
Further, in S240, it is determined whether the angular velocity information acquired this time is valid data, including; determining a modulus of angular acceleration based on the angular velocity measurement; based on the modulus of the angular acceleration, whether the angular velocity measured value acquired at this time is effective data or not is judged. Since only a small number of angular velocity information acquired by the angular velocity sensor is selected as a data basis for judging whether to wake up the air mouse when the air mouse wake-up method provided by the present disclosure is executed, it may result in different time intervals of acquisition time of adjacent two angular velocity information selected as the data basis. The method comprises the steps of judging whether the angular velocity measured value acquired at this time is effective data based on a model of angular acceleration, and judging whether the angular velocity measured value acquired at this time is effective data based on the change amount of angular velocity in unit time. The method is equivalent to converting the change condition of angular velocity of different time lengths into the change condition of angular velocity of the same time length, and can ensure that the finally obtained judgment result is accurate.
Further, "based on the modulus of angular acceleration, judging whether the angular velocity measurement value acquired this time is valid data", including: and judging whether the acquired angular velocity information is effective data or not based on the magnitude relation between the modulus of the angular acceleration and the angular acceleration threshold value.
On the basis of the technical scheme, optionally, the method further comprises: and if the first time interval is greater than or equal to the first time interval threshold value, the accumulated number of continuous effective data acquisition is 0. Since the first time interval is greater than or equal to the first time interval threshold, the action is not consistent in the time period from the current time to the time of last updating the accumulated number of times of continuously collecting the effective data, and the action of not corresponding to the same swinging action of waking up the air mouse in the time period can be considered. Therefore, the accumulated number of the continuous effective data collection is cleared by 0, so that the intention of the holder of the air mouse is accurately judged next time.
On the basis of the technical scheme, optionally, the method further comprises: if the angular velocity measured value acquired at this time is not effective data, the accumulated times of continuously acquiring the effective data are not updated.
Fig. 3 is a flowchart of yet another air mouse wake-up method provided in an embodiment of the present disclosure. Fig. 3 is a specific example of fig. 1. Illustratively, referring to FIG. 3, the method includes:
s301, periodically acquiring angular velocity information of an air mouse, wherein the angular velocity information comprises angular velocity measurement values and angular velocity measurement value acquisition time.
For example, in the angular velocity information acquired at time t, the angular velocity measurement value is (ω x,t,ωy,t,ωz,t), and the angular velocity measurement value acquisition time is t.
S302, determining a first time interval between the angular velocity measured value acquisition time and the accumulated time of last updated continuous effective data acquisition.
Illustratively, the accumulated time of last updated continuously collecting effective data is set to be t score, and the first time interval Δt1=t-t score.
S303, judging whether the first time interval is larger than a first time interval threshold, if yes, executing S310, and if not, executing S304.
For example, the first time interval threshold is set to T timeout, and this step determines the magnitude relationship between Δt1 and T timeout.
S304, determining the current angular velocity measured value acquisition time and a second time interval of the last execution time of the step of judging whether the current acquired angular velocity measured value is valid data.
For example, the execution time of the last step of determining whether the current acquired angular velocity measurement value is valid data is set to t check, and the second time interval Δt2=t-t check.
S305, judging whether the second time interval is larger than a second time interval threshold value; the second time interval is larger than the time interval of acquiring the angular velocity information of the air mouse twice; if yes, S306 is executed, and if no, S311 is executed.
Illustratively, the second time interval threshold is set to T check, and this step determines the magnitude relationship between Δt2 and T check.
S306, judging whether the angular velocity measured value acquired at this time is effective data, and updating and executing the execution time of the step of judging whether the angular velocity measured value acquired at this time is effective data; if the determination result is execution S307, if the determination result is execution S312.
Illustratively, setting the angular acceleration threshold as a, optionally, when executing the step, firstly obtaining a module of the angular velocity measurement value acquired this time (i.e. the angular velocity measurement value acquired at the time t) and a module of the valid data determined last time; determining a model of angular acceleration based on the model of the angular velocity measured value acquired at this time and the model of the effective data determined last time; based on the modulus of the angular acceleration, whether the angular velocity measured value acquired at this time is effective data or not is judged.
Exemplary, the last determined effective data is set to be modulo omega t-1, and the current acquired angular velocity measurement is modulo omega t-1 Mode of angular acceleration/>And updates t check. Judgment/>And the magnitude relation with A to determine whether the angular velocity measured value acquired at this time is effective data.
S307, updating the accumulated times of continuously collecting the effective data, and recording the collection time of the collected angular velocity measured value.
Illustratively, ifThe angular velocity measured value acquired at this time is considered as effective data, the accumulated number s of continuous acquisition of the effective data is updated, and t score is updated.
S308, judging whether the accumulated number of the current continuous acquisition effective data is larger than an updating threshold value, if so, executing S309, and if not, executing S313.
Illustratively, the update threshold is set to S0, and the magnitude relation between S and S0 is determined.
S309, waking up the air mouse.
Illustratively, if S > S0, the air mouse is awakened.
S310, the accumulated times of continuously collecting effective data are cleared to 0.
S311, discarding the acquired angular velocity information.
S312, the accumulated times of continuously collecting the effective data are not updated, and the collecting time of the collected angular velocity measured value is not recorded.
Illustratively, the accumulated number s of continuously acquired valid data is not updated, nor is t score updated.
S313, not waking up the air mouse.
According to the technical scheme, the angular velocity information is considered from multiple angles (such as the continuity of motion, the duration of motion and the swing amplitude of motion), and the motion characteristics of the air mouse are determined so as to judge the intention of a holder of the air mouse, so that the accurate recognition of the awakening motion can be realized. According to the technical scheme, in the whole execution process, the purpose of judging the intention of an air mouse holder and waking up the air mouse in time can be met only by reporting low-frequency data, and in the whole execution process, the calculation amount is low and the power consumption is low.
In addition, in the technical scheme, the first time interval threshold, the second time interval threshold, the angular acceleration threshold and the updating threshold can be set according to the user requirements so as to meet the wake-up requirements of different scenes, and the system has expandability and customizable performance. For example, for the air mouse which is matched with the intelligent television and serves as a remote controller, through reasonable setting of the parameters, the air mouse can be awakened only when a user throws the air mouse forcefully for many times or swings the air mouse in a certain direction to a large extent, and the phenomenon that the user does not wake the air mouse by mistake when using other functions can be avoided. Aiming at the air mouse matched with the computer, through reasonable setting of the parameters, the air mouse can be awakened only by lifting the air mouse, and the awakening sensitivity of the air mouse can be improved.
In the above technical solution, the current continuous collection of effective data may be further set to have the accumulated number of times greater than the update threshold, and the collection time t of the current angular velocity measurement value and the time interval of last waking up the air mouse are greater than the preset wake-up interval, so that the operation of waking up the air mouse is executed this time. The arrangement can avoid the frequent report of the instruction of waking up the air mouse to the electronic equipment (such as an intelligent television or a computer, etc.) matched with the air mouse, and can reduce the calculation amount of the electronic equipment matched with the air mouse.
