Hi Martin,

There is currently no explicit blink detection exposed through the EyeX Engine API.

You could implement a blink detection filter yourself by using the eye position data stream (TX_INTERACTIONBEHAVIORTYPE_EYEPOSITIONDATA). When the eye lid is closed there is no eye position data, so blinking corresponds to the gaps in the stream of eye position data for the respective eye. The gaps in the data can be calculated from the timestamps of the data packages. This way, blink detection can be made per eye.
