personally I make the objects I want to interact with "sensible" to optical flow: ie. I fit the grid of my optical flow on the portion of the screen occupied by the object i want to move. this way i obtain  what you could call a "mousemoved" effect, as I can drag and/or rotate stuff. (look here to see what i mean).

for the "mousepressed" thing maybe optical flow alone is not the best tool as it can't guess gestures. the easiest thing to do is to make your interface in such a way that it doesn't need mouse clicks (personally I make draggable buttons etc.)
