A method and device for identifying and reminding abnormal blinking movements

Abstract

The present invention relates to a method and device for identifying and reminding abnormal blinking movements. The device used in the method includes: a wearable terminal device, a cloud signal processing unit, and a processing result feedback unit; wherein, the wearable terminal device is worn by a tester The body is used to capture and transmit the blinking movement data of the tested person; the cloud signal processing unit is used to calculate the blinking movement data of the tested person; the processing result return unit is responsible for sending the abnormal blinking movement results that need to be prompted by the cloud signal processing unit through wireless The network sends back to the wearable terminal device; the cloud signal processing unit, through wireless signal reception, processes the blinking movement data of the tested person in three stages: the first stage is to calculate the baseline data of the tested person’s blinking movement; the second stage , to capture the eye blinking data in the question-and-answer stage of the test question; in the third stage, compare the eye blinking data in the second stage with the baseline data of the eye blinking in the first stage and perform relative calculations, and filter to obtain abnormal eye blinking results.

Description

technical field [0001] The invention relates to a method and device for identifying and reminding abnormal blinking movements, belonging to the field of intelligent expression recognition. Background technique [0002] A microexpression is a very rapid expression that lasts only 1 / 25 to 1 / 5 of a second and expresses real emotions that a person is trying to suppress and hide. Microexpressions are very fleeting, involuntary facial expressions that humans reveal when they try to suppress or hide their true emotions. As an effective clue to identify lies, micro-expressions can be applied in security, justice, clinical and other fields. [0003] Existing wearable (portable) facial expression recognition devices are divided into two categories, one is worn on the person being tested, the other is worn on the tester, and some of them are fixed cameras for the tester, which are non-portable but have the same function as the first one. The second category is similar. [0004] The ...

[0005] The second category is the equipment worn or used by the tester, which captures and recognizes the expression and blinking movements of the tester outside the body of the tester. The shortcomings of this type of equipment are very obvious

Therefore, this kind of equipment can only play the role of "performing expression" recognition, but cannot capture and analyze the subtle expressions and abnormal blinking movements that represent the true state of mind of the testee
