Track Blink State

[grahamfogartyplus]

There is no mention in the Sdk documentation for support for blink detection. Will this feature be added in the near future??

Blink detection is in our roadmap, but at this point we cannot provide information about when it will be added to the software.

Javier, any update on blink detection?

One "naive" way to detect blinks is to monitor the datastream for momentarily lost tracking which could indicate a blink event. I've made a little application called GazePlotWPF that draws the x/y/pupilsize for each eye and flashes the background when a potential blink occurred. It's not 100% accurate but could be enough to get some ideas going.



Source code is available on Github. I've also made a pre-compiled binary for your delight.

Proper eyelid closure and accurate blink detection is still on the roadmap, ETA unknown.
