Development of Eye Blink Rate Level Classification System Utilizing Sitting Postural Behavior Data

Haehyun Lee, Taekbeom Yoo, Soomin Hyun, Donghyun Beck, Woojin Park
2021 IEEE Access  
Although low eye blink rate (EBR) has been pointed out as one of the main risk factors for DES, it is difficult for office workers to continuously monitor and increase their own involuntary blinking, especially  ...  The real-time EBR level classification system is expected to contribute to preventing/relieving DES and thereby enhancing the eye health of office workers.  ...  One feasible approach for this new system would be to estimate EBR with factors indirectly related to eye blinking.  ...
