The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the disclosure and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations (or steps) can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of an application control method provided in an embodiment of the present invention. The method and the device for controlling the target application on the terminal equipment can be suitable for the situation of quickly and accurately controlling the target application on the terminal equipment. The method may be performed by an application control apparatus, which may be implemented in software and/or hardware, and may be configured in an electronic device having a network communication function. As shown in fig. 1, the application control method provided in the embodiment of the present application may include the following steps:
and S110, determining a target knocking vibration signal generated by effective knocking operation acting on a preset human body area.
In this embodiment, fig. 2 is a schematic diagram of different tapping positions of a human body region provided in an embodiment of the present invention. Referring to fig. 2, the human body has a complicated structure, so that different knocking vibrations are generated when knocking is performed at different parts of the human body region. For example, taking an arm area in a human body area as an example, when a finger taps different positions in the arm area, different tapping vibrations are generated. Although human ears feel similar to the vibration at different positions and cannot sense the vibration signals at different positions in a distinguishing way, the vibration sensors can capture different vibration signals.
In this embodiment, referring to fig. 2, the preset body area may be a body arm area, and at least two preset tapping positions may be preset in the preset body area. The user can select one preset knocking position from a plurality of preset knocking positions in the preset human body area according to the requirement to perform knocking operation. The effective knocking operation may be an operation of performing knocking at any preset knocking position in the preset human body area. Based on the principle that the vibration sensor can capture different knocking vibration signals generated at different knocking positions, the vibration sensor can be used for detecting the knocking vibration signals generated by effective knocking operation of a user acting on a preset human body area, and the knocking vibration signals are recorded as target knocking vibration signals for distinguishing. Alternatively, the vibration sensor may include an accelerometer sensor and a gyroscope sensor; for example, to ensure that sufficient vibration signal data can be collected, the accelerometer sensor may employ a 6-axis accelerometer to collect multiple vibration signals simultaneously.
S120, determining a target knocking position of the effective knocking operation in a preset human body area according to the target knocking vibration signal; wherein the tapping operation at different tapping positions produces different tapping vibration signals.
In the embodiment, when the knocking operation is performed at different knocking positions of the preset human body area, the generated knocking vibration signals are different. On the basis, after the target knocking vibration signal is determined, it can be identified at which preset knocking position of the preset human body area the effective knocking operation is performed, the target knocking vibration signal can be generated, and the preset knocking position capable of generating the target knocking vibration signal in the preset human body area can be recorded as the corresponding target knocking position.
In this embodiment, different preset tapping positions can be pre-marked for tapping operation, so as to generate standard tapping vibration signals, and the preset tapping positions and the corresponding standard tapping vibration signals are correlated. On the basis, after the target knocking vibration signal is determined, the standard knocking vibration signal generated by executing the knocking operation at which preset knocking position of the preset human body area is similar to the target knocking vibration signal can be identified, and then the preset knocking position associated with the similar standard knocking vibration signal is used as the target knocking position of the effective knocking operation in the preset human body area.
And S130, controlling the target application related to the control equipment according to the operation information related to the target knocking position.
In the present embodiment, referring to fig. 2, different operation information may be set for each preset tap position in the preset human body area, each operation information being related to each function of the target application. For example, taking the target application as a music-type application as an example, the preset tap position No. 1 shown in fig. 2 indicates returning to the home page, the preset tap position No. 2 indicates opening the music application, the preset tap position No. 3 indicates playing a song in the music application, the preset tap position No. 4 indicates pausing the playing of the music application, the preset tap position No. 5 indicates playing a previous song, and the preset tap position No. 6 indicates playing a next song. In this way, the control device can generate a target control instruction of a target application associated with the control device according to the operation information associated with the target tapping position, so as to perform function control on the target application.
In the embodiment, the control device can be integrated with a vibration sensor and worn near a preset human body area; for example, the control device may be a smart watch. The control device can be in communication connection with the target application on the terminal device, and can send the generated target control instruction to the target application of the terminal device through the communication connection to control various functions of the target application.
The embodiment of the application provides an application control method, when a user needs to perform function control on a target application, the user does not need to take out a terminal device where the target application is located and perform control operation on a mobile terminal device, and does not need to execute some special knocking times or knocking actions to perform control, and only needs to perform simple knocking operation at a preset knocking position of a set human body area, so that the target application can be controlled to realize the function related to the preset knocking position, the control process of the target application is simplified, meanwhile, the target application can be quickly and accurately controlled, and human-computer interaction experience is enhanced.
Fig. 3 is a flowchart of another application control method provided in the embodiment of the present invention. The technical solution of the embodiments of the present application is optimized based on the above embodiments, and the embodiments of the present application may be combined with various alternatives in one or more of the above embodiments. As shown in fig. 3, the application control method provided in the embodiment of the present application may include the following steps:
s310, determining the amplitude of a part of vibration signals in the initial vibration signals acquired by a preset vibration sensor; the preset vibration sensor is arranged at a preset distance of a preset human body area.
In this embodiment, this vibration sensor can set up in the predetermined distance department of predetermineeing the human body region, guarantees that the position of setting up of vibration sensor can not predetermine the position of strikeing too far away from predetermineeing in the human body region, avoids as far as possible because the vibration sensor is too far away from predetermineeing the position of strikeing and leads to catching and carry out the produced vibrations signal that strikes of operation predetermineeing the position of strikeing.
In the present embodiment, the vibration sensor may capture the vibration signal, but the vibration signal is not usually screened and captured, so the initial vibration signal detected by the vibration sensor may only include the tapping vibration signal generated by performing the effective tapping operation at any one of the preset tapping positions of the preset human body area; or may also include only vibration signals due to other factors; or it may also include a combination of vibration signals generated by both of the above factors. For this purpose, after obtaining the initial vibration signal captured by the vibration sensor, the amplitude of the initial vibration signal captured by the vibration sensor may be detected to determine amplitude information of at least a portion of the initial vibration signal. Optionally, after the vibration sensor captures the initial vibration signal, the captured initial vibration signal may be written into the buffer, and at this time, traversal monitoring may be directly performed on the initial vibration signal in the buffer in sequence, and the amplitude of a part of the vibration signal in the initial vibration signal is read.
In this embodiment, optionally, if the vibration sensor is always in the vibration signal detection stage, it is necessary to acquire the vibration signal data in real time, which wastes detection resources. For this reason, a detection activation mechanism needs to be provided for the vibration sensor to reduce the influence of the above real-time detection.
In this embodiment, optionally, after the vibration sensor is activated, some vibration signals generated by the non-tapping operation of the user may be captured by the vibration sensor, and once data similar to the tapping vibration signal but not the tapping vibration signal is detected by the vibration sensor, and the captured vibration signals generated by the non-tapping operation are similar to the tapping vibration signal generated by the effective tapping operation, if subsequent control is performed according to such vibration signals, it is likely to cause misoperation. For this reason, after the vibration sensor is activated, it is possible to detect whether a preset operation of the gyroscope in the vibration sensor, for example, a rotation operation of a preset angle occurs. If the gyroscope is subjected to preset operation, a vibration signal detected by the vibration sensor is used for carrying out a subsequent control processing process; otherwise, the vibration signal detected by the vibration sensor may not be processed temporarily.
S320, if the amplitude of the partial vibration signal is determined to be larger than the effective knocking threshold value, determining a target knocking vibration signal generated by effective knocking operation acting on a preset human body area, and determining a target starting position and a target ending position in the initial vibration signal.
In this embodiment, the effective tapping threshold may be used to determine whether the initial vibration signal includes a tapping vibration signal generated by an effective tapping operation. If the amplitude of the read partial vibration signal is larger than the effective knocking threshold value in the process of traversing and reading the initial vibration signal, the initial vibration signal is considered to contain a target knocking vibration signal generated by effective knocking operation acting on a preset human body area. At this time, it is necessary to continuously determine the starting position and the ending position of the target tapping vibration signal in the initial vibration signal so as to extract the portion of the vibration signal from the initial vibration signal as the target tapping vibration signal.
In an alternative manner of this embodiment, the operation of determining the target tapping vibration signal generated by the effective tapping operation on the preset human body area, the target starting position and the target ending position in the initial vibration signal, may include steps a1-a 2:
step a1 is to set, as the target start position, a signal position at which the amplitude of the signal detected for the first time is greater than the tapping vibration threshold value in the process of detecting the amplitude of the initial vibration signal.
In this embodiment, the effective tapping threshold is set to identify whether the initial vibration signal includes a target tapping vibration signal generated by an effective tapping operation, so that a relatively large effective tapping threshold is set to avoid an identification error. The tapping vibration threshold is used for identifying the beginning and the end of the target tapping vibration signal from the initial vibration signal, so that the size of the tapping vibration threshold needs to be smaller than that of the effective tapping threshold, and thus the false deletion of the beginning part and the end part of the target tapping vibration signal can be avoided. The effective knocking threshold value can be dynamically determined according to the sum of the noise mean value and the 3-time standard deviation of the target knocking vibration signal, and the knocking vibration threshold value is dynamically determined according to the sum of the noise mean value and the 1-time standard deviation of the target knocking vibration signal.
In this embodiment, the amplitude of the initial vibration signal written in the buffer may be sequentially detected, and when it is detected that the signal amplitude is larger than the tapping vibration threshold, the position where the signal amplitude is larger than the tapping vibration threshold may be recorded. In the case where it is determined that the amplitude of a part of the vibration signal in the initial vibration signal is greater than the effective tapping threshold value, the recorded position where the amplitude of the signal is greater than the tapping vibration threshold value may be directly used as the target start position.
Step a2 is to set, as the target end position, a signal position at which the detected signal amplitude is continuously smaller than the tapping vibration threshold while continuing to detect the amplitude of the initial vibration signal.
In this embodiment, when it is determined that the amplitudes of some of the initial vibration signals are greater than the effective tapping threshold, the amplitudes of the remaining initial vibration signals can be continuously detected in sequence. When a signal having a signal amplitude continuously smaller than the tapping vibration threshold value is detected to occur in the remaining initial vibration signals, the signal position at which the signal amplitude is continuously smaller than the tapping vibration threshold value may be regarded as the target end position.
In this embodiment, when the vibration sensor acquires at least two initial vibration signals, for example, the vibration sensor may include a 6-axis accelerometer, and the 6 initial vibration signals may be captured in real time by the 6-axis accelerometer, and the signals captured in real time are written into the buffer. Optionally, because each path of initial vibration signal is captured and collected synchronously, amplitude detection can be performed on any path of initial vibration signal captured by the vibration sensor to determine the target starting position and the target ending position, and detection is not required to be performed on each path of initial vibration signal to determine the starting position and the ending position, so that the waste of computing resources is avoided.
By adopting the mode, the target knocking vibration signal generated by effective knocking operation can be simply and quickly found out at the initial position and the end of the initial vibration signal, so that the target knocking vibration signal can be extracted later.
S330, determining the vibration signal from the target starting position to the target ending position in the initial vibration signal as a target knocking vibration signal.
In the present embodiment, the target tap vibration signal is extracted from the initial vibration signal in accordance with the target start position and the target end position. And judging whether the length of the target knocking vibration signal meets a preset signal length condition or not. If the length of the target knocking vibration signal meets the condition, entering the next process; otherwise, returning to re-determining the target starting position and the target ending position so that the length of the re-extracted target knocking vibration signal meets the preset signal length condition.
In this embodiment, under the condition that the vibration sensor acquires at least two paths of initial vibration signals, the target tapping vibration signals corresponding to the respective paths of initial vibration signals can be respectively extracted from the respective paths of initial vibration signals according to the target starting position and the target ending position. And then, splicing the extracted target knocking vibration signals corresponding to all paths according to a preset sequence to obtain a complete target knocking vibration signal.
In an optional manner of this embodiment, after determining the vibration signal from the target start position to the target end position in the initial vibration signal as the target tapping vibration signal, steps B1-B3 may further be included:
and step B1, under the condition that the vibration sensor acquires at least two paths of initial vibration signals, filtering the target knocking vibration signals extracted from the initial vibration signals.
In this embodiment, there may be other vibration disturbances during the user's tapping process, such as a fist making motion being mistaken for tapping, and other large-amplitude motions of the user being detected by the accelerometer and gyroscope being mistaken for tapping. Since these motions are all at high frequencies, 10hz high-pass filtering processing can be performed on the target tap vibration signal extracted from the initial vibration signal.
And step B2, determining the signal-to-noise ratio of the target knocking vibration signal according to the pre-filtering signal and the post-filtering signal of the target knocking vibration signal.
And step B3, if the signal-to-noise ratio of the target knocking vibration signal is greater than a preset signal-to-noise ratio threshold, determining that the target knocking vibration signal belongs to an effective knocking vibration signal.
In the embodiment, after filtering the target tapping vibration signal containing noise signals caused by the motion of making a fist and other motions of large amplitude, the signal-to-noise ratio of the noise signals is obviously lower than that of the tapping vibration signal. Respectively calculating the energy of the first m points and the energy of the second m points of the filtered target knocking vibration signal, judging whether the signal-to-noise ratio of the target knocking vibration signal is greater than a signal-to-noise ratio threshold value, and if so, judging that the signal is an effective knocking vibration signal; otherwise it is considered a noise signal. And then, sequentially splicing the extracted multi-path target knocking vibration signals.
The method has the advantages that the target knocking vibration signal can be effectively identified, the situation that the amplitude of the vibration signal caused by some special actions is similar to that of the knocking vibration signal generated by effective knocking operation, and the vibration signal generated by ineffective knocking operation is mistaken for the knocking vibration signal generated by effective knocking operation, so that the follow-up error control on target application is caused is avoided.
S340, determining a target knocking position of effective knocking operation in a preset human body area according to the target knocking vibration signal; wherein the tapping operation at different tapping positions produces different tapping vibration signals.
And S350, controlling the target application related to the control equipment according to the operation information related to the target knocking position.
The embodiment of the application provides an application control method, when a user needs to perform function control on a target application, a target knocking vibration signal which is useful for an identification signal can be accurately extracted according to effective knocking operation of the user, and then a target knocking position is determined according to the extracted target knocking vibration signal, so that the user does not need to take out terminal equipment where the target application is located and perform control operation on mobile terminal equipment, and does not need to execute some special knocking times or knocking actions for control, and the target application can be controlled to realize the function related to the preset knocking position only by performing simple knocking operation at the preset knocking position of a set human body area, the control process of the target application is simplified, meanwhile, rapid and accurate control over the target application can be realized, and man-machine interaction experience is enhanced.
Fig. 4 is a flowchart of another application control method provided in the embodiment of the present invention. The technical solution of the embodiments of the present application is optimized based on the above embodiments, and the embodiments of the present application may be combined with various alternatives in one or more of the above embodiments. As shown in fig. 4, the application control method provided in the embodiment of the present application may include the following steps:
and S410, determining a target knocking vibration signal generated by effective knocking operation acting on a preset human body area.
And S420, determining the target tapping vibration characteristic information of the target tapping vibration signal.
In this embodiment, time-frequency analysis may be performed on the target knocking vibration signal to obtain time-domain characteristic information and frequency-domain characteristic information of the target knocking vibration signal, and the time-domain characteristic information and the frequency-domain characteristic information may be combined to obtain target knocking vibration characteristic information of the target knocking vibration signal. Optionally, discrete short-time fourier transform may be performed on the target knocking vibration signal to obtain frequency spectrum information representing frequency domain characteristics of the target knocking vibration signal, and meanwhile, time domain characteristic information of the target knocking vibration signal may also be obtained to obtain target knocking vibration characteristic information. For example, the following formula is used to calculate the spectrum information:
where x [ n ] is the input signal, w [ n-m ] is the window function, and m is the displacement; and combining the frequency spectrum information and the time domain characteristic information, and sequentially splicing into complete target knocking vibration characteristic information.
In this embodiment, the target tap vibration feature information may include feature vectors of multiple dimensions, and the feature vectors of different dimensions have different importance. Therefore, the characteristic information with the highest score of 50% can be selected by adopting the Fisher score to serve as the final target knocking vibration characteristic information, and therefore the subsequent identification accuracy can be improved. For example, the fisher score is calculated as follows:
wherein r represents a frequency point position, niIndicates the number of samples of the i-th class, uiAnd
the mean and variance of the samples representing the ith class, and u represents the mean of all classes of the dimensional feature.
S430, determining standard knocking vibration characteristic information matched with the target knocking vibration characteristic information from a preset knocking vibration characteristic set; and one standard knocking vibration characteristic information in the knocking vibration signal set is associated with a unique preset knocking position.
In an alternative manner of this embodiment, determining standard tapping vibration characteristic information that matches the target tapping vibration characteristic information from a preconfigured tapping vibration characteristic set may include steps C1-C2:
and step C1, determining the feature information similarity between the target tapping vibration feature information and each standard tapping vibration feature information in the pre-configured tapping vibration signal set.
And step C2, determining at least one standard tapping vibration characteristic information with the highest characteristic information similarity as the standard tapping vibration characteristic information matched with the target tapping vibration characteristic information.
In the embodiment, the nearest neighbor algorithm is used to calculate the similarity between the target tapping vibration characteristic information and each standard tapping vibration characteristic information in the tapping vibration signal set, and the standard tapping vibration characteristic information with the highest similarity is used as the matched standard tapping vibration characteristic information. Optionally, the calculating the similarity is to calculate the feature information similarity between the target tapping vibration feature information and each standard tapping vibration feature information in a pre-configured tapping vibration signal set by combining the euclidean distance and a dynamic time programming algorithm.
In an alternative manner of the present embodiment, before determining the standard tapping vibration feature information matching the target tapping vibration feature information from the preconfigured tapping vibration feature set, steps D1-D3 are further included:
and D1, receiving a training knocking vibration signal generated by effective knocking operation of a user on a preset knocking position of the preset human body area when the training knocking vibration signal is used for the first time.
