Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Fig. 2 is a flowchart of a key operation triggering method based on a heart rate signal according to an embodiment of the present invention. The key operation triggering method based on the heart rate signal comprises the following steps:
step S1: collecting the light signal reflected by the detected part and detecting the intensity of the reflected light signal.
In the embodiment of the present invention, the purpose of step S1 is to determine whether the optical signal reflected by the detected portion is a human optical signal.
When light of a specific wavelength is irradiated to the skin surface of a human body, the absorption rate and the reflectance to the light show a specific ratio due to the optical characteristics of the skin. According to the characteristic, whether the optical signal reflected by the detected part is a human optical signal can be judged.
Optionally, after the device is turned on, the light emitting power of the incident light source is automatically reduced, the light signal reflected by the detected part is collected, the intensity of the reflected light signal is detected, and whether the received light signal is a human light signal or not is judged.
Referring to fig. 3, a schematic diagram of a human body optical signal and a non-human body optical signal according to an embodiment of the present invention is shown. Δ DC1 represents the signal strength of light reflected from a non-human body surface back to the device sensing means. In general, since light is difficult to transmit into the inside of the non-human body, the non-human body optical signal does not have intensity variation caused by the light transmitting into the inside of the non-human body. Δ DC2 represents the signal strength of light reflected back to the device sensing means from the surface of the human skin, while Δ AC2 represents the signal strength of light transmitted into the human body and then reflected back to the device sensing means. When the incident light source irradiates the human skin surface with a certain light intensity, the intensity of the signal reflected by the human skin surface is in a fixed threshold range, and when the Δ DC2 is in the fixed threshold range (when the light intensity of the incident light source is different, the fixed threshold range in which the intensity of the signal reflected by the human skin surface is different), it can be determined that the sensed optical signal is a human optical signal.
Step S2: and when the intensity of the reflected light signal is within a preset threshold range, continuously collecting the reflected light signal within a period of time.
In the embodiment of the present invention, if the optical signal reflected by the detected portion is a human body optical signal, the step S2 is implemented to determine whether the stability of the reflected optical signal meets the requirement of collecting the heart rate signal.
Optionally, when the intensity of the reflected light signal is within a preset threshold range, the reflected light signal is continuously collected within 100 milliseconds, and the intensity change of the reflected light signal within 100 milliseconds is detected.
Specifically, reflected light signals in a time period are continuously collected, and if the intensity fluctuation range of the reflected light signals is stable within a preset fluctuation range within 100 milliseconds (the preset fluctuation range refers to that the intensity normal fluctuation range of the reflected light signals corresponding to different light intensities in a normal fluctuation range corresponding to the light intensity of an incident light source is different when the light intensities of the incident light sources are different), the stability of the reflected light signals is considered to meet the requirement of collecting heart rate signals.
Step S3: and when the intensity of the reflected light signal is stable within a preset variation range within the period of time, acquiring a heart rate signal through the detected part, and detecting the intensity of the heart rate signal.
Optionally, when the intensity of the reflected light signal is stable within a preset variation range within 100 milliseconds, the heart rate signal is acquired through the detected part.
Optionally, the light is emitted to the measured portion, the intensity of the emitted light is sufficient to transmit into the measured portion, the light signal reflected by the inside of the measured portion is received, and the light signal reflected by the inside of the measured portion is analyzed to obtain the heart rate signal.
The volume of blood inside the body will exhibit specific changes as the heart beats. When light is transmitted to the inside of the human body, the blood volume in the light-transmitted portion will also exhibit a certain change.
Referring to fig. 4, a diagram of the signal intensity Δ AC2 of the light transmitted into the human body and reflected back to the sensing device of the apparatus according to the embodiment of the present invention is shown. The changing characteristic of the Δ AC2 is a changing characteristic of the blood volume in the light-transmitting portion, i.e., a heart rate characteristic of a human body. Thus, the change in signal strength of the human heart rate signal can be reflected in the change in signal strength of Δ AC2 that light is transmitted into the human body and then reflected back to the device sensing apparatus.
Optionally, increasing the light emitting power may increase the intensity of the light signal, making the characteristics of the acquired heart rate signal more apparent.
Step S4: and when the intensity of the heart rate signal is smaller than a preset threshold value within a period of time, triggering key operation.
When the key is pressed, the human tissue at the light transmission part is extruded by the equipment, blood is not circulated due to the compression of subcutaneous tissues such as blood vessels, and the heart rate signal is also weakened or even disappears under the influence of the subcutaneous tissues. The greater the pressure on the keys, the more pronounced the weakening of the heart rate signal.
Referring to fig. 5, the characteristics of the heart rate signals at different pressure values according to the embodiment of the present invention are shown. The pressure value increased from 100g to 500g upon compression, and a single increase of 100g, it can be clearly observed in fig. 5 that the intensity of the heart rate signal gradually decreased with the increase of the pressure value. The subcutaneous tissues such as blood vessels are compressed, so that blood does not flow, and the intensity of the heart rate signal is weakened or even disappears. The heart rate of a normal person is 30 BPM-220 BPM (Beat Per Minute beats Per Minute), so that at least half of the heart rate waveform can be detected within 1 second.
Optionally, the heart rate signal of 1 second is continuously collected, the intensity of the heart rate signal is detected, the peak-peak value of the intensity fluctuation of the heart rate signal within 1 second is detected, and when the peak-peak value is smaller than a preset threshold value, a key operation is triggered.
Optionally, when the peak-to-peak value is detected to be greater than the preset threshold, the heart rate signal of 1 second is continuously acquired. And then searching the wave crest and the wave trough of the heart rate signal, and triggering key operation when the maximum peak-peak value is smaller than a preset threshold value.
According to the key operation triggering method based on the heart rate signal, whether the human body optical signal exists or not is judged by collecting the optical signal reflected by the detected part and detecting the intensity of the reflected optical signal. And when the intensity of the reflected light signal is within a preset threshold range, continuously collecting the reflected light signal within a period of time, detecting the intensity change of the reflected light signal within 100 milliseconds, and judging whether the stability of the reflected light signal meets the requirement of collecting the heart rate signal. When the intensity of the reflected light signal is stable within a preset variation range within 100 milliseconds, continuously collecting a heart rate signal for 1 second, detecting the intensity of the heart rate signal, detecting the intensity fluctuation peak-peak value of the heart rate signal within 1 second, and triggering the key operation when the peak-peak value is smaller than a preset threshold value. Therefore, the key operation triggering method based on the heart rate signal can reduce hardware for realizing key operation and is beneficial to realizing extremely simplified and highly integrated hardware.

Optionally, the optical signal collection module 100 emits light to the measured portion, and the intensity of the emitted light is sufficient to transmit into the measured portion. The optical signal collection module 100 receives an optical signal internally reflected by the portion to be measured. The optical signal acquisition module 100 analyzes the optical signal reflected inside the detected part to obtain a heart rate signal.

If the fluctuation range of the optical signal is stabilized within a preset fluctuation range within 100 milliseconds (the preset fluctuation range refers to that the normal fluctuation range of the optical signal corresponding to the different light intensities of the incident light source is different when the light intensities of the incident light sources are different), the stability of the optical signal is considered to meet the requirement of collecting the heart rate signal.
