Thanks Mike,
I already configured the settings and actions.  However, I've reset them and tried again.
Smile and turn head right/left seem to be the only ones responding consistently.
Others are either not responding or going crazy, for example raising eyebrows to go to next page results on multiple pages being turned or showing and hiding the audio player multiple times if it's the action assigned to it.
Blink either right or left eyes won't respond at all.
Turning head up/down is registered when I test it but it won't perform the action when using it.  It also seem to get confused when raising eyebrows, so for example tilting the head up it often registers raising eyebrows and tilting head down it also registers raising eyebrows immediately after probably because raising the head back also raises the eyebrows points.
Anyway, I'll keep experimenting and hopefully some can be actually used reliably.
