Detect blinking

[willwade]

As a professional we find many people might not be able to do the eye movements but blink is possible. We'd like a simple way of detecting voluntary blinks. Ie filtering out shorter blinks.

Needed. Thoughts

• somehow use a opencv approach to this
• or train a different or same model to detect it. Will need labelled data for this

Maybe of interest. NB I found changing the threshold value to 4.5 from 5.5 (https://github.com/Asadullah-Dal17/Eyes-Position-Estimator-Mediapipe/blob/dd29b1e2120cbeaeda2dded2ef31291953b4b8c8/Eye_Tracking_part2/main.py#L109) - more reliable. For us we should have this as variable..
