Method and device for judging conscious blinking and unconscious blinking

Abstract

The invention discloses a method and device for judging conscious blinking and unconscious blinking. The method comprises the steps of carrying out experiments of unconscious blinking and conscious blinking on a testee; acquiring an electric signal of graphene resistance change when the testee performs the conscious blinking and the unconscious blinking through a graphene sensor attached to the orbicularis oculi muscle of the testee, and obtaining detection ranges of a time characteristic and a peak characteristic of the unconscious blinking of the testee, and detection ranges of a time characteristic and a peak characteristic of the conscious blinking of the testee; obtaining an electric signal of graphene resistance change when the testee blinks at a time in a non-experimental state, andextracting a time characteristic and a peak characteristic of the obtained electric signal; and judging the conscious blinking and the unconscious blinking according to the time characteristic and the peak characteristic extracted in the previous step. The method is not affected by the environment, and can judge the conscious blinking and the unconscious blinking more stably, reliably and accurately.

Description

technical field [0001] The invention relates to a method for distinguishing between conscious blinking and unconscious blinking based on graphene sensors and radio frequency technology. The flexible graphene stress sensor and RFID passive tag technology are used to read and transmit blinking signals, and the time characteristics and peak values ​​of the signals are used. The feature enables the distinction between conscious and involuntary blinks. Background technique [0002] With the continuous advancement of technology and society, new interactive methods are introduced, bringing user experience that traditional interactive methods do not have. For special groups of people who have lost the ability to move and operate, the use of blinking for interactive control has also become a reliable tool for them to better integrate into the current society. In addition, the blink signal can also distinguish the fatigue state of the person. [0003] Blinking can be divided into un...

Problems solved by technology

[0004] The current blink detection methods are mainly the image analysis method based on the camera and the blink signal detection method based on the eye tracker, both of which have high requirements on the environment, for example, when the ambient light is poor, the detection results will be greatly affected

[0005] In the current academic research, the method of distinguishing between conscious blinking and unconscious blinking is mainly to set electrodes around the eyes, use the potential difference to directly collect the electro-oculogram signals generated by the muscles themselves, and then make judgments based on the collected electro-oculogram signals. Electrical signals are greatly interfered by electrical signals from other body parts
