How do I make touch controls motion controls?

How do I make touch controls motion controls, mostly for android ios and web os. I already found how to put it on I just don't know how to use it. I would like when user touches one sprite it moves left and when user touches other sprite it moves right. Please Help! <img src="smileys/smiley4.gif" border="0" align="middle" /> <img src="smileys/smiley19.gif" border="0" align="middle" />

Use an event something like:

+ Is touching BigLeftButton

-> Player: simulate control left

+ Is touching BigRightButton

-> Player: simulate control right

etc.
