javascript, is there a way to set a (smaller) threshold on touchmove event

At this moment my touch input device generates a touchmove event (after a touchstart event) AFTER a number of pixels have been moved (I think it’s about 10 pixels)
This means that when using this technique to draw with my finger on the canvas, the first part of a curve is always a straight line with length 10 pixels.
I want a touchmove event after just 2 or 3 pixels after the touchstart event. Is there some sort of threshold I can manipulate?
