It should be noted that, as long as no conflict is formed, each embodiment of the present invention and each feature of each embodiment may be combined with each other, and the formed technical solutions are all within the protection scope of the present invention.
Additionally, the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer executable instructions, and although a logical order is illustrated in the flowcharts, in some cases the steps illustrated or described may be performed in an order other than that herein.
Referring to fig. 1, the method for controlling an electronic device provided by the present invention includes: s101, receiving elastic wave signals generated by external touch of electronic equipment through a plurality of sensors attached to the electronic equipment, and converting the elastic wave signals into voltage signals; s102, acquiring touch object information of the electronic equipment according to the voltage signal analysis; s103, calculating and obtaining characteristic information corresponding to the voltage signal according to the voltage signal; s104, obtaining corresponding pre-stored feature vectors according to the touch object information, comparing the feature information with the feature vectors, and obtaining pre-stored control instructions according to the comparison result to control the electronic equipment. In the above embodiments, the sensor may include one or more of a piezoceramic sensor, a resistive strain gauge, a grating pressure sensor, a thin film piezoelectric sensor, and the like having a sensor for detecting an elastic wave signal; the touch object information includes: finger-abdomen touch information, finger joint touch information, object touch information, nail touch information, and the like; when an external object (such as a finger, a finger joint, a touch pen, a finger nail and the like) touches the electronic equipment, an elastic wave signal is generated, the elastic wave signal is captured by the sensor and then converted into a voltage signal with the same frequency as the elastic wave signal, the voltage signal is only convenient for post calculation, the converted voltage signal can be the same as the elastic wave signal in frequency, and can be converted into voltage signals with different frequencies in actual work, and the voltage signal can be correspondingly regulated in post calculation; then, based on the principle that the materials or structures of different touch objects are different, the generated elastic waveforms are also different; further calculating and analyzing according to the voltage signals to obtain touch object information and corresponding characteristic information of the elastic wave signals; the characteristic information can be used for identifying actions such as multi-tap, hard tap and the like of a user; finally, a pre-stored feature vector is obtained according to the touch object information, the feature vector is used as a threshold value, and when the feature information generated by touch is larger than the threshold value, the operation can be confirmed to be the real intention of the user and is correspondingly controlled; of course, it should be noted that, in the actual work, other methods exist for judging the actual intention of the user, and the present invention will be further described later, so that it will not be described here; as for the control manner of controlling the electronic device according to the pre-stored control command, those skilled in the art may select to use according to actual needs, and the present invention will not be described in detail herein.
Referring to fig. 2, in the above embodiment, the step S102 of obtaining touch object information of touching the electronic device according to the voltage signal analysis includes: s201, comparing the component duty ratio of each frequency band of the voltage signal on the frequency domain and the waveform characteristics on the time domain with a pre-stored corresponding table respectively, and obtaining the closest touch object information according to the correlation coefficient between the two; s202, obtaining touch object information touching the electronic equipment according to the closest touch object information. For example, the finger joints have more high-frequency components than the finger flanks, and have more late oscillating waveforms, long duration, less oscillating waveforms of the finger flanks and short duration. Of course, in actual working, other modes can be adopted to identify the touch object information corresponding to the elastic wave signals, for example, a machine learning algorithm and/or a deep learning algorithm are used for establishing a characteristic model; then, according to the voltage signals and the characteristic model, calculating to obtain touch object information corresponding to the voltage signals; for example, a worker may collect elastic wave signals generated by touching electronic devices with different objects in advance, convert the elastic wave signals into voltage signals, and train the voltage signals according to a machine learning algorithm and/or a deep learning algorithm as input signals to obtain a feature model for associating the voltage signals with corresponding touching objects; at the moment, the voltage signal is used as input, the corresponding touch object is used as output, and a characteristic model is established through a deep learning algorithm or a machine learning algorithm; and then when the actual user touches the electronic equipment through different objects, the converted voltage signals can be analyzed and calculated through the characteristic model to obtain the corresponding touch objects. In actual work, a characteristic model can be obtained by collecting voltage signals generated by massive touch and utilizing the voltage signals through a machine learning algorithm and/or a deep learning algorithm, and related information of a touch object can be obtained by the characteristic model and the voltage signals generated by actual touch of a user in the later period; the present invention is not particularly limited herein, and those skilled in the art can select and use the present invention according to actual needs.
In order to provide a more diversified control manner of the electronic device, referring to fig. 3, in an embodiment of the invention, the calculating the characteristic information corresponding to the voltage signal according to the voltage signal may include: s3011, extracting a plurality of comparison feature vectors corresponding to the touch times according to the voltage signal when the electronic equipment is touched for a plurality of times in a preset period time; s3012 takes any one of the comparison feature vectors as a feature source and respectively compares the feature source with other comparison feature vectors to obtain a plurality of comparison results; s3013, generating characteristic information corresponding to the voltage signals according to a plurality of comparison results; s3021, extracting a comparison feature vector according to the voltage signal when the electronic device is touched only once in a preset period time; s3022, comparing the comparison feature vector with a pre-stored feature vector to obtain a comparison result; and S3023, generating characteristic information corresponding to the voltage signal according to the comparison result. Specifically, the characteristic vector αn represents the characteristic vector generated when different gestures or different objects touch the device, and the comparison characteristic vector αn [ i ] in the characteristic vector can be a time domain characteristic, a frequency domain characteristic, a phase characteristic and the like; when a user touches the electronic equipment for the nth time within the period time, the sensor generates a corresponding voltage signal, and according to the characteristics of the signal, a characteristic vector alpha n of the voltage signal is extracted, wherein the characteristic vector comprises a plurality of comparison characteristic vectors alpha n [ i ], and n is more than or equal to 1; at this time, because the user stores the feature vectors of alpha 1, beta·alpha n in the n-time touching process, the comparison feature vector alpha 1[i of the feature vector alpha 1 is used as a feature source, and the feature vectors are sequentially compared with the comparison feature vector in the feature vector alpha 2, beta 1, beta n-1 in sequence, and corresponding feature information is produced according to the comparison results; if n=1, the comparison feature vector α 1[i of the feature vector α1 is compared with the comparison feature vector α 0[i of the pre-stored feature vector α0, and the comparison result is β0, which is also the subsequent feature information. Of course, the above examples are only for convenience of describing the feature information generating process, and in actual work, any one of the plurality of comparison feature vectors may be used as the feature source, and the present invention is not limited in any way.
In order to facilitate improvement of recognition accuracy of a user touching an electronic device, in an embodiment of the present invention, obtaining a corresponding pre-stored feature vector according to the touch object information, comparing the feature information with the feature vector, and obtaining a pre-stored control instruction according to the comparison result to control the electronic device further includes: and comparing the characteristic information with the characteristic vector, and obtaining a pre-stored control instruction to control the electronic equipment when each comparison result in the characteristic information is larger than the characteristic vector.

When each comparison result in the characteristic information is larger than the characteristic vector, a corresponding pre-stored control instruction is obtained according to the energy value of the voltage signal to control the electronic equipment; wherein the energy value of the voltage signal is an accumulated value or an average value of the energy values of the comparison feature vectors. Specifically, a threshold value β may be set, where the threshold value β represents a touch intensity threshold corresponding to the touch object, that is, the feature vector; comparing whether beta 0, beta N-1 is larger than a threshold beta, and if beta 1, beta N-1 is larger than beta, determining that N touches are the same touch behavior. Otherwise, the touch behaviors are different; the result of this determination may be used to wake up the trigger conditions of the relevant application. For example, a notebook in sleep is awakened, a switch is controlled, and the like, and of course, in actual work, different touch behaviors can also be correspondingly allocated with a required control instruction, for example, the same touch behavior is used for controlling the switch notebook, and different touch behaviors can be used for playing music, and the like.
In the above embodiment, the energy value of the voltage signal can be obtained mainly by calculation by the following formula:
in the formula, E is the energy value of the voltage signal, and m is the number of the acquired signal points; n is the number of signal points determined by selecting the voltage signal wavelength with a predetermined length according to the actual situation, and a person skilled in the art can select the setting according to the actual requirement, which is not limited herein.
