Google's library does a poor job of reporting eye coordinates. There is almost no difference between an eye closed versus open. So I had to rely on one of their features where they provide a probability that each eye is open. A wink, in this case, is when there is a large probability that one eye is open and the other isn't. If this isn't working for you, it means Google's library cannot clearly identify when your eyes are open or closed. I'm not sure there is much I can do about that I'm afraid.
The head tilt detection is just based on a rotation amount. The gesture starts when the head is tilted less than 8 degrees up or down (so mostly center) and triggers when the head has tilted more than 16 degrees. It then waits until the head is less than 8 degrees again before starting the next gesture. If you are triggering this, it means your head is moving up or down more than 8 degrees at a time which is a lot. The gesture size increases or decreases the amount of rotation required. If you set the gesture size to the largest, MobileSheets will require 28.8 degree rotation. I'm not sure how you could possibly generate false positives with that... So if you haven't tried increasing the gesture size, start by increasing one at a time and then testing.
Open mouth is one of the more simple ones, but determining the amount the mouth has to be open to trigger is somewhat complicated. Increase the gesture size will require the mouth to be open more, but this is not one where false positives should be generated as the mouth has to be mostly closed to even start the gesture. If you are leaving your mouth open the entire time while playing, then this is probably not the best gesture to use unless you use a really large gesture size. If the largest gesture size isn't large enough, I can always increase the offset a little more.
