Theorically, it should detect that user press at the same point, center of screen, right? But in practical, it's not non linear function. So the result is different and available for developer to detect.</p> <p>That's the secret behine my NeuSense Engine. ;)</p> <p>Sittiphol</p> http://blogs.forum.nokia.com/blog/sittiphol-phanvilais-forum-nokia-blog/2009/03/03/neusenseengine-multi-point-touch-screen-engine-for-s60-5th#comment24919 <p>Hi!<br /> Quite interesting idea. And what are the technical details of the realization? I assume that in case of sequential pointer events you get coordinates of the "middle points", e.g. when at first touch top-left circle then top-right circle - you get pointer event with y-coordinate = top and x-coordinate = (right-left)/2. Is it so?</p> <p>Yeah, I know, you wouldn't disclose the truth :)</p> http://blogs.forum.nokia.com/blog/sittiphol-phanvilais-forum-nokia-blog/2009/03/03/neusenseengine-multi-point-touch-screen-engine-for-s60-5th#comment24917
