Blink detection method and apparatus based on dynamic threshold, device, and storage medium

The application provides an eye blinking detection method and device based on a dynamic threshold, equipment and a storage medium. The eye blinking detection method based on the dynamic threshold comprises the following steps: S1, acquiring an electromyographic signal set; the electromyographic signal set comprises electromyographic signals of an eye region of a user corresponding to a current time window and / or at least one time window before the current time window; S2, extracting an eye blinking feature parameter of each electromyographic signal in the electromyographic signal set; S3, updating an eye blinking detection threshold based on the eye blinking feature parameter; and S4, performing eye blinking detection by using the updated eye blinking detection threshold. The method can dynamically update the eye blinking detection threshold based on the electromyographic signals of the user, realize adaptive adjustment of the threshold, and help improve the accuracy of detecting eye blinking of the user.

Method and system for detecting concussion

A method for identifying an occurrence of a concussion in a subject involves capturing eye blink raw data from at least one eye of the subject. The method next involves analyzing the eye blink raw data to generate at least a first subject specific eye blink metric and determining that a significant difference exists between the first subject specific eye blink metric and a predefined normal value. Next, the occurrence of the concussion in the subject may be identified, based on determining that the significant difference exists.

Computer controlled contact-lens-based video recording using machine learning

A computer controls a recording device within a contact lens environment. The computer receives a video signal from a Video Recording Device (VRD) within a contact lens environment proximate an eye of a user. The computer controls the VRD, and the video signal provides a substantially real-time representation of a monitored zone. The computer receives eye blinking metadata for the user and generates a blinking pattern using a machine learning model trained to determine eye blinking patterns from metadata. The computer establishes a recording routine characterized by periods of recording and pausing substantially synchronized to the blinking pattern. The computer directs, in response to receiving a start signal, the VRD to record the video signal in accordance, at least partially, with the recording routine. The computer identifies within the video signal, a recording modification trigger condition and initiating a corrective action in response thereto.
