Hi @tw2018, no I am afraid there is no blink detection samples included with the Core SDK. you would need to implement your own algorithm for this purpose.
You may find the following thread @ https://developer.tobii.com/community/forums/topic/blink-detection/ useful to get you started.
Essentially, one needs to have a loop counter that detects a blink based upon duration of gaze lost time which for a blink is approximately 300 ms.
Check out the info, and let us know if you require further assistance in this respect.
Could you kindly clarify what you mean by camera window? If you mean some graphical heads up display of eye locations then this is not an integrated command I am afraid, but please let me know if this is not what you were looking for.
