Also be aware that if you can't achieve 100% reliable gesture detections, it is worth experimenting with half page turns or scrolling by partial pages. In that way it isn't a disaster if a gesture is not detected sometimes, you can repeat it again. From my personal experience, the two gestures which work best for me are 'Open mouth' and 'Smile' N.B. The smile is a smile with open lips, closed lips doesn't work at all for me.
