Blinking, a rapid eye closure action called temporal reflexes; involuntary blinking of the human body is actually a protective action that distributes tear evenly over the cornea and conjunctiva to maintain the cornea and conjunctiva moist, and the blinking action also temporarily rests the retina and eye muscles to relieve eye fatigue. According to statistics, normal people blink about 15 times per minute on average, normally blink about once every 2-6 seconds, and the duration of each blink is 0.2-0.4 second. According to related researches, the blink frequency is closely related to the physiological and psychological conditions of people, the blink frequency of people is increased under the stress state, and the blink frequency is reduced when people meet with the spirit: when reading books and newspapers, the blink frequency is not more than 10 times/minute, the blink frequency is only 5 times/minute when using a computer, and the blink frequency can be as low as 3 times/minute when playing games.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

In one embodiment, as shown in fig. 1, a blink monitor 10 is provided, the blink monitor 10 may comprise: a micro-motion sensor 11 and a blink detection module 12 electrically connected to each other; the micro-motion sensor 11 can be attached around the orbicularis oculi muscle of the tested object and is used for collecting the orbicularis oculi muscle micro-motion signal; the blink detection module 12 may be configured to determine a current blink parameter of the subject according to the orbicularis oculi micro-movement signal; the blink parameters include a blink duration and a blink frequency.

In this embodiment, the subject may be a human being, or may be another subject having orbicularis oculi muscles such as an animal. When the tested object uses the eye-wearing device, the micro-motion sensor can be attached to the periphery of the orbicularis oculi muscle of the tested object; the orbicularis oculi muscle surrounds the eye for a circle, and the eye blinking can be controlled through contraction and relaxation, so that the micro-motion sensor can detect the pressure, displacement and other changes of the contact part of the orbicularis oculi muscle, and the pressure changes can be reflected in the orbicularis oculi muscle micro-motion signals acquired by the micro-motion sensor.

It can be understood that the micro-motion sensor is attached around the orbicularis oculi muscle of the detected object, and detects the micro-motion signal of the orbicularis oculi muscle through direct contact, so that the micro-motion sensor is not easily interfered by external electromagnetic waves and human body motion, and the accuracy rate of blink detection can be improved.

Alternatively, the Micro-motion sensor may be a MEMS (Micro-Electro-mechanical system) Micro-motion sensor, which has the advantages of small size, light weight, high sensitivity, low energy consumption, etc. The micro-motion sensor may be, but is not limited to, an acceleration sensor, a pressure sensor, a displacement sensor, a gyroscope, a velocity sensor, a piezoelectric film, and the like, which can detect a micro-motion signal.

The micro-motion sensor can be electrically connected with the blink detection module through a lead wire, or can be connected through an electric socket or other electric connection modes. Optionally, the blink monitor comprises two micro-motion sensors, the two micro-motion sensors may be respectively attached around orbicularis oculi muscles of left and right eyes of the subject when the subject uses the eye-worn device, and the blink detection module may be respectively electrically connected with the two micro-motion sensors.

In this embodiment, the blinking duration refers to the time taken for the subject to complete a single blinking action, and the blinking frequency refers to the frequency of blinking actions of the subject, which may be the number of blinks per minute. The following briefly describes the process of determining the current blink parameters of the subject by the blink detection module according to the orbicularis oculi micro-motion signals.

The blink detection module can acquire orbicularis oculi micro-motion signals acquired by the micro-motion sensor in real time, can perform signal processing such as filtering, noise elimination and amplification on the orbicularis oculi micro-motion signals, and then performs signal analysis on the processed orbicularis oculi micro-motion signals. The preset time period can be 3-10 seconds, 10 seconds-1 minute and the like, or longer, and can be determined according to actual requirements or actual debugging results.

Taking time domain analysis as an example, referring to fig. 2, because there is large oscillation in the orbicularis oculi micro-movement signal when the eye blinks, the signal analysis can be performed through a preset time window (the size of the time window can match the general blinking duration, for example, the size of the preset time window is 0.2 seconds): the blink detection module can determine a peak and a trough in a time window corresponding to an initial time node of a preset time period, and obtains a maximum amplitude change value of the time window by calculating a difference value between the peak and the trough in the time window; if the maximum amplitude variation value is smaller than a preset amplitude variation threshold value, moving the time window to a next time node through a preset time step (which is smaller than a preset time window, such as one tenth of the time window, for example, 20 milliseconds); if the maximum amplitude variation value is greater than or equal to a preset amplitude variation threshold value, the blink detection module can preliminarily determine that the time window is associated with one blink action, increase one blink time, and move the time window to the next time node by taking the size of the time window as a step length; and the time window is moved to the end time node of the preset time period. It is understood that the accumulated blink frequency is the blink frequency in the preset time period, so that the current blink frequency can be calculated. Certainly, in this embodiment, the blink detection module may further obtain the energy value by integrating the signal in the time window, and when the energy value is greater than or equal to the preset energy threshold, the blink detection module may preliminarily determine that the time window is associated with a blink action, and the blink frequency is increased by one, and the time window moving logic refers to the above description, which is not described herein again.

In addition, the blink detection module may perform further signal analysis on the orbicularis oculi micro-movement signal within the time window associated with the one-time blink action to obtain the blink time duration. Specifically, the blink detection module can sample the orbicularis oculi micro-motion signal in the time window according to a preset sampling rate, find a peak sampling point with the maximum amplitude value from sampling acquisition sampling points, and an initial sampling point and a termination sampling point of a peak corresponding to the peak sampling point, and calculate the time length between the termination sampling point and the initial sampling point to be used as the blink time length of one blink action associated with the time window, so that the average blink time length of each blink time in the preset time period can be calculated to be used as the current blink time length. Wherein, the determination of the initial sampling point of the peak may be as follows: the blink detection module can calculate the difference value between a sampling point and a left adjacent sampling point of a peak sampling point from the peak sampling point and the left adjacent sampling point, and when the difference value is less than 0, any one of the two sampling points at the moment is selected as the initial sampling point of the peak; the determination of the ending sample point of a peak can likewise be as follows: the blink detection module can calculate the difference value between the sampling point and the right adjacent sampling point of the peak sampling point from the peak sampling point and the right adjacent sampling point, and when the difference value is smaller than 0, any one of the two sampling points at the moment is selected as the stop sampling point of the peak.

In this embodiment, the blink detection module may further determine the preliminarily determined blink action by determining the blink time length of each time, so as to obtain a more accurate blink time length and blink frequency. Specifically, the blink detection module may determine whether the blink duration of one blink action associated with the time window matches a standard blink duration (0.2 to 0.6 seconds), and if so, finally determine that the time window is associated with one blink action, add one to the blink frequency, and record the blink duration of the blink action; if not, finally determining that the time window is irrelevant to the blinking action, and adding zero to the blinking times or keeping the blinking times unchanged. For example, if the maximum amplitude variation value in a certain time window is greater than or equal to the preset amplitude variation threshold, but the blinking duration corresponding to the time window is 0.8 seconds, the blinking number is not changed, and the time window is moved to the next time node by the preset time step.

It will be appreciated that real-time monitoring of blink parameters is crucial for certain specific populations, for example: the blinking frequency and the blinking time duration are closely connected with the fatigue degree of a person, and the blinking frequency and the blinking time duration can be used for judging whether a driver is tired or not and ensuring safe driving; the blink frequency can also reflect the concentration degree of a person in the working and reading processes, the low blink frequency means higher concentration, and the increased blink frequency means lower concentration; the blinking frequency can also monitor healthy eyes of children (or white-collar workers and other objects) to avoid visual deterioration caused by excessive eye use; finally, blinking frequency may also indicate early stage ocular pathologies such as dry eye or other nervous system related ocular pathologies.

In summary, in the blink monitor of the embodiment, the micro-motion sensor can be attached around the orbicularis oculi muscle of the detected object, and the micro-motion signal of the orbicularis oculi muscle is detected by direct contact, so that the blink monitor is not easily interfered by external electromagnetic waves and human body movement, can improve the accuracy of blink detection, can accurately monitor the blink parameter of the detected object in real time, and is convenient for subsequent monitoring of eye fatigue or eye pathological changes and the like based on the blink parameter.

Referring to fig. 3, the blink detection module 12 may include: the signal receiving circuit 121 and the processor 122 are electrically connected to each other, wherein the signal receiving circuit 121 is configured to acquire and amplify the orbicularis oculi micro-motion signal acquired by the micro-motion sensor 11 in real time; the processor 122 is configured to determine a current blink parameter of the subject according to the amplified orbicularis oculi micro-movement signal.

The signal receiving circuit can comprise a signal amplifier, and can amplify the initial orbicularis oculi muscle micro-motion signal for subsequent processing. The processor may be, but not limited to, a Processing device such as a CPU (Central Processing Unit) or an MCU (micro controller Unit).

Taking the MCU as an example, if the orbicularis oculi micro-motion signal is an analog signal, the MCU may be integrated with an analog-to-digital converter for converting the analog signal into a digital signal to obtain a digital signal type orbicularis oculi micro-motion signal, and performing signal processing on the orbicularis oculi micro-motion signal to obtain current blink parameters.

Specifically, referring to fig. 4, the MCU122 may include a signal processing module 1221, a state determination module 1222, a motion detection module 1223, and a blink determination module 1224. The signal processing module 1221 is electrically connected to the signal receiving circuit 121, the state determining module 1222 and the motion detecting module 1223, respectively, and the blink determining module 1224 is electrically connected to the state determining module 1222 and the motion detecting module 1223, respectively. It can be understood that the signal processing module, the state determination module, the motion detection module, and the blink determination module may be implemented by hardware circuits.

Taking a blink monitor comprising two micro sensors as an example, a signal processing module can filter two routes of orbicularis oculi micro signals of left and right eyes collected by the micro sensors, each route of original signal is decomposed into two routes of orbicularis oculi micro signals, a first group of left and right routes of orbicularis oculi micro signals can be subjected to 1Hz low-pass filtering, and two routes of low-frequency baseline drift signals, namely motion signals of a detected object, are output and used for detecting the current object state of the detected object, wherein the object state comprises a static state and a motion state; the second group of left and right eye orbicularis oculi muscle micro-motion signals can be subjected to 2Hz high-pass filtering to obtain two high-frequency signals, namely blink signals, and the two high-frequency signals are used for detecting the action state of the orbicularis oculi muscles, namely detecting whether blinking occurs and the blinking time length. For example, the signal processing module may include a splitter and a filter circuit electrically connected to each other, the filter circuit including a high pass filter circuit and a low pass filter circuit.

The state judgment module can receive two paths of baseline drift signals and can judge whether a tested object is in a motion state or a static state through amplitude variation amplitude, because when the tested object moves (walks, kicks, swims and the like), the orbicularis oculi micro-motion signals collected by the micro-motion sensor also have low-frequency large-amplitude variation along with motion rhythm, the module can store the baseline drift signals within a period of time (3-10 s), calculate the signal variation amplitude between a wave crest and a wave trough by detecting the wave crest and the wave trough of the signals, and determine that the current object state of the tested object is in the motion state if the signal variation amplitude is larger than or equal to a preset variation amplitude threshold value; if the signal variation amplitude is smaller than a preset variation amplitude threshold value, determining that the current object state of the tested object is a static state; after the judgment is finished, the module inputs the judgment result of the current object state into the next module, namely a blink judgment module.

The action detection module can receive two paths of high-frequency signals, and the blinking action is performed in a very short time, so that the blinking action is reflected as a high-frequency component of the orbicularis oculi micro-movement signal, and the blinking action of the detected object can be detected through the high-frequency signals. Most blinking actions are completed by two eyes synchronously, so that when large-amplitude oscillation occurs in two paths of high-frequency signals simultaneously, the blinking actions can be preliminarily judged, and the duration of the oscillation is further detected; and since the blink duration is generally 0.2-0.6 s, when the oscillation duration is in the range, adding 1 to the module blink count, and recording the blink duration. The module periodically transmits the blinking times and the duration to the next module, namely a blinking judgment module, and the transmission period is consistent with the state judgment module. The above specific signal processing procedure may refer to the above description of performing signal processing by using a time window, and is not described herein again.

The blink judgment module can receive the processing results of the state judgment module and the action detection module and respectively count the blink parameters of the detected object in the static state and the moving state. In addition, the blink judgment module can also acquire a plurality of historical object states of the tested object and a plurality of historical blink parameters corresponding to the historical object states; and determining the characteristic blink parameters of the tested object in a static state and the characteristic blink parameters of the tested object in a motion state according to the historical object state and the historical blink parameters of the tested object. The blink judgment module can judge whether abnormal conditions such as overuse of eyes and the like occur or not by comparing the characteristic blink parameters with the current blink parameters; whether abnormal conditions such as abnormal blinking and the like of the tested object occur or not can be determined through the statistic value of the blinking parameter of the tested object and the healthy blinking parameter in a longer period; the blink judgment module can also send out warning messages after judging the abnormal conditions.

In addition, the blink detection module may further include a communication module, which is electrically connected to the processor and configured to send the blink parameters of the subject to a terminal device; and the terminal equipment is in communication connection with the communication module. Referring to fig. 4, the communication module 123 is electrically connected to the MCU122, and the module may integrate wireless communication modules such as WIFI (wireless fidelity) or bluetooth, and may be used to connect to the mobile terminal, upload blink data such as blink times and blink duration to the mobile terminal application, and the mobile terminal application may generate an eye report for viewing according to the blink data.

Referring to fig. 4, the blink detection module may further include a power module 124, which is electrically connected to the signal receiving circuit 121, the MCU122, and the communication module 123, respectively, for supplying power. Referring to fig. 4, the MCU122 may further include an alarm module 1225, a storage module 1226, and the like. The alarm module can be electrically connected with the blink judgment module and is used for receiving the warning information sent by the blink judgment module, conducting a corresponding alarm switch and triggering alarm hardware to send out an alarm; the alarm hardware can be selected from a buzzer, a loudspeaker, an LED (light emitting diode) lamp and other devices to give out sound or give out light alarm; the alarm module may include a register for storing custom alarm settings, configurable parameters as follows: excessive eye use prompting time, eye fatigue prompting time, regular rest reminding and the like. The storage module can locally store blink data and can be electrically connected with the blink judgment module and the communication module respectively. It should be noted that the alarm module and the storage module may be integrated in the micro control unit, or may be separate modules.

Referring to the description of the blink monitor, in the eye-wearing device of the embodiment, the micro-motion sensor can be attached to the periphery of the orbicularis oculi of the detected object, and the micro-motion signal of the orbicularis oculi is detected through direct contact, so that the eye-wearing device is not easily interfered by external electromagnetic waves and human body motion, the accuracy of blink detection can be improved, the blink parameter of the detected object can be accurately monitored in real time, and the subsequent monitoring of eye fatigue or eye pathological changes and the like based on the blink parameter is facilitated.

Thus, the cluster can be tightened when the eye wears the device.
