Description
Technical Field
The present disclosure relates to the field of air mouse technologies, and in particular, to an air mouse wake-up method and apparatus, an electronic device, and a storage medium.
Background
An air mouse (air mouse for short) is an input device, can operate a screen cursor like a traditional mouse, but can be directly used by shaking in the air without being placed on any plane.
At present, a wake-up mode commonly adopted by an air mouse is to collect a linear acceleration value of the air mouse from a triaxial acceleration sensor, and wake up the air mouse when a modulus of the linear acceleration value exceeds a preset linear acceleration threshold value.
In practice, the three-axis acceleration sensor collects the linear acceleration of the air mouse in three coordinate axis directions under the self coordinate system of the three-axis acceleration sensor. Due to the influence of gravity, the data acquired by the three-axis acceleration sensor are added with the components of the gravity acceleration in three axes. Research shows that in practice, as the three-axis acceleration sensor is fixed on the air mouse, when the attitude of the air mouse changes, the directions of three coordinate axes of the coordinate system of the three-axis acceleration sensor also change, and the components of the gravity acceleration in the three axes also change correspondingly. Therefore, when the air mouse in different postures swings in the same direction by a large margin, the influence of the gravity acceleration on a linear acceleration mode is different. Resulting in some gestures where the user swings in some motion, the air mouse can be awakened. In other postures, the user swings in the same action and cannot wake up the air mouse. Namely different postures and the same action, and the difficulty level of awakening the air mouse is inconsistent.

Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
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 in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
Fig. 1 is a flowchart of an air mouse wake-up method according to an embodiment of the present disclosure, where the present embodiment is applicable to a case where an air mouse is woken up from a sleep state, the method may be executed by an air mouse wake-up apparatus, the apparatus may be implemented in a software and/or hardware manner, and the apparatus may be configured in the air mouse. As shown in fig. 1, the method may specifically include:
s110, periodically acquiring angular speed 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. Illustratively, the angular velocity sensor may be a gyroscope or an inertial measurement system.
And S120, judging whether the angular speed information meets a preset awakening condition or not based on the angular speed information.
There are various specific implementation methods of this step, and optionally, the angular velocity information includes an angular velocity measurement value, and a reference threshold value is preset. The specific implementation method of the step 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 the preset awakening condition or not based on the magnitude relation between the angular velocity measurement value and the reference threshold value.
Exemplarily, if the angular velocity measurement value is greater than the reference threshold value, it is determined that the angular velocity information satisfies a preset wake-up condition; and if the angular velocity measurement value is smaller than or equal to the reference threshold value, determining that the angular velocity information does not meet the preset awakening condition.
And 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 is that the air mouse is awakened by means of the angular velocity information instead of the linear acceleration acquired by the triaxial acceleration sensor, the air mouse is determined to be awakened, the interference of the gravity acceleration is avoided in the whole judging process, and the air mouse can be swung in the same action when the air mouse is in different postures, and the awakening difficulty degree 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 characteristics: the method is characterized in that the action is a coherent action, the action lasts for a certain time, but the duration is shorter; second, the action has a certain amplitude, which causes abrupt change of angular velocity. Based on this, optionally, S120 is provided, including: determining whether the motion to be recognized is continuous or not based on the angular velocity information; if the action to be recognized is continuous, judging whether the action to be recognized is a wake-up action; if the action to be recognized is a wake-up action, determining whether the angular velocity information meets a preset wake-up condition; otherwise, determining that the angular speed information does not meet the preset awakening condition. The step of determining whether the action to be recognized is continuous is to verify the first characteristic, and the step of determining whether the action to be recognized is a wake-up action is to verify the second characteristic. The setting can realize accurate identification of the awakening action.
Fig. 2 is a flowchart of another air mouse wake-up method according to an embodiment of the present disclosure. Fig. 2 is a specific example of fig. 1. Exemplarily, referring to fig. 1, the method comprises:
s210, periodically acquiring angular velocity information of the air mouse, wherein the angular velocity information comprises an angular velocity measurement value and an angular velocity measurement value acquisition time.
S220, determining a first time interval of the acquisition time of the angular velocity measured value and the time of updating the accumulated times of continuously acquired effective data last time.
The valid data is response data of angular velocity information due to a human waking motion. Illustratively, 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 measurement value a is considered to be caused by the human wake-up motion, and therefore 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 assumed that the angular velocity is not caused by human waking motion, and thus the angular velocity measurement c is not valid data.
And S230, judging whether the first time interval is larger than a first time interval threshold value.
The swing action for awakening the air mouse usually lasts for a period of time, and the essence of the step is to judge whether the acquisition time of the angular velocity measurement value acquired this time and the time of the last time of updating the accumulated times of continuously acquired effective data correspond to the same action to be identified. If the first time interval is smaller than the first time interval threshold, it is indicated that the action to be recognized is continuous in a time period from the time of updating the accumulated times of continuously collecting the valid data to the time of collecting the angular velocity measurement value obtained this time, and it can be considered that the same action to be recognized corresponds to the time period. If the first time interval is greater than or equal to the first time interval threshold, it is indicated that the action to be recognized is discontinuous in a time period from the time of updating the accumulated times of continuously acquired valid data to the time of acquiring the angular velocity measurement value acquired this time, and it may be considered that the action to be recognized does not correspond to the same action to be recognized in the time period. This step verifies the first characteristic of the wake-up action described above.
And S240, if the first time interval is smaller than the first time interval threshold, judging whether the angular velocity measured value acquired this time is effective data.
In practice, the swing action for waking up the air mouse often needs to have a large swing amplitude, and the essence of this step is to determine whether the swing amplitude of the air mouse is large enough, and whether the swing action for waking up the air mouse is currently performed by the user.
And S250, if the angular velocity measured value acquired this time is effective data, updating the accumulated times of continuously acquiring the effective data.
And S260, if the accumulated times of continuously collecting the effective data is larger than the updating threshold value, awakening 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 currently waking up the air mouse satisfies a certain duration. And if the accumulated times of continuously collecting the effective data is greater than the updating threshold value, namely the duration of the swing action of awakening the air mouse at present reaches a certain time length, determining that the action to be identified is an awakening action, and awakening the air mouse.
S240-S260 are verification of the wake action feature one and feature two above.
The essence of the above technical solution is that the angular velocity information is considered from a plurality of angles (such as continuity of motion, duration of motion, and swing amplitude of motion), and the motion characteristics of the air mouse are determined to determine the intention of the air mouse holder, which can realize accurate identification of the wake-up motion.
On the basis of the above technical solution, optionally, the method further includes: recording the execution time of each step of judging whether the collected angular velocity measurement value is valid data; at this time, S240 may be replaced with: if the first time interval is smaller than the first time interval threshold, determining the acquisition time of the angular velocity measurement value and a second time interval of the execution time of the step of judging whether the angular velocity measurement value acquired at the time is valid data or not at the last time; judging whether the second time interval is greater than a second time interval threshold value; the second time interval is greater than the time interval of acquiring the angular speed information of the air mouse twice; and if the second time interval is greater than the second time interval threshold, judging whether the angular velocity measured value acquired this time is effective data.
In practice, the duration of the swing action for waking up the air mouse is often much longer than the time interval between the acquisition moments of two adjacent angular velocity sensors, so that the essence of the arrangement is that when the air mouse wake-up method provided by the present disclosure is executed, only a few times of angular velocity information acquired by the angular velocity sensors are selected as a data basis for judging whether to wake up the air mouse; instead of using all the angular velocity information acquired by the angular velocity sensor as a data basis for judging whether to awaken the air mouse or not, the calculation amount of the air mouse awakening 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 collected this time is valid data, including; determining a norm of the angular acceleration based on the angular velocity measurement; and judging whether the angular velocity measured value acquired this time is effective data or not based on the mode of the angular acceleration. Since only a few times of angular velocity information collected by the angular velocity sensor is selected as a data basis for determining whether to wake up the air mouse when the air mouse wake-up method provided by the present disclosure is performed, it may cause a difference in time interval between the collection times of two adjacent times of angular velocity information selected as the data basis. "based on the model of the angular acceleration, whether the angular velocity measurement value collected this time is valid data" is judged, and it is substantially based on the amount of change in the angular velocity per unit time, whether the angular velocity measurement value collected this time is valid data is judged. The method is equivalent to converting the change conditions of the angular velocities in different time lengths into the change conditions of the angular velocities in the same time length, and the final obtained judgment result can be ensured to be accurate.
Further, "judge whether the angular velocity measurement value collected this time is valid data based on the model of the angular acceleration", includes: and judging whether the angular velocity information collected this time is effective data or not based on the magnitude relation between the modulus of the angular acceleration and the angular acceleration threshold.
On the basis of the above technical solution, optionally, the method further includes: and if the first time interval is greater than or equal to the first time interval threshold, clearing 0 the accumulated times of continuously acquiring the effective data. Because the first time interval is greater than or equal to the first time interval threshold, it is indicated that the motion is discontinuous in the time period from the current time to the time of updating the accumulated times of continuously collecting the valid data last time, and it can be considered that the same swing motion for waking up the air mouse is not corresponding to the time period. Therefore, the accumulated times of continuously collecting effective data is cleared to 0, so as to ensure that the intention of the air mouse holder is accurately judged next time.
On the basis of the above technical solution, optionally, the method further includes: and if the angular velocity measured value acquired this time is not valid data, not updating the accumulated times of continuously acquiring the valid data.
Fig. 3 is a flowchart of another air mouse wake-up method according to an embodiment of the present disclosure. Fig. 3 is a specific example of fig. 1. Illustratively, referring to fig. 3, the method includes:

And S308, judging whether the accumulated number of the current continuous effective data acquisition is greater than an updating threshold value, if so, executing S309, and if not, executing S313.
Illustratively, the updating threshold value is set to S0, and the magnitude relation between S and S0 is judged.

Illustratively, the accumulated number s of continuously collected valid data is not updated, nor is t updatedscore。
And S313, not waking up the air mouse.
According to the technical scheme, the angular velocity information is considered from a plurality of angles (such as the continuity of the action, the duration of the action and the swing amplitude of the action), the motion characteristics of the air mouse are determined, the intention of the air mouse holder is judged, and the awakening action can be accurately identified. According to the technical scheme, in the whole execution process, the intention of the air mouse holder can be judged only by means of low-frequency data reporting, and the air mouse can be awakened in time.
In addition, in the above technical scheme, the first time interval threshold, the second time interval threshold, the angular acceleration threshold and the update threshold can be set according to user requirements to meet awakening requirements of different scenes, and the method has expandability and customizability. For example, for an air mouse serving as a remote controller and matched with a smart television, through reasonable setting of the parameters, the air mouse can be awakened only when a user forcibly swings the air mouse for many times or swings the air mouse greatly along a certain direction, and the adverse phenomenon that the air mouse is mistakenly awakened when the user does not use other functions can be avoided. Aiming at the air mouse matched with a computer, the air mouse can be awakened only by lifting the air mouse through reasonable setting of the parameters, and the awakening sensitivity of the air mouse can be improved.
In the basis of the above technical scheme, it may also be set that the cumulative number of times of continuously acquiring valid data at present is greater than the update threshold, and the acquisition time t of the current angular velocity measurement value and the time interval of waking up the air mouse for the last time are greater than a preset wake-up interval, then the operation of waking up the air mouse is executed this time. The setting can avoid that the air mouse frequently reports the instruction of waking up the air mouse to the electronic equipment (such as an intelligent television or a computer) matched with the air mouse, and can reduce the calculation amount of the electronic equipment matched with the air mouse.
