how to detect the shape that touch the touch screen
<p>I have received requirement like this <a href="http://www.youtube.com/watch?v=7MYQicokwmY&amp;feature=plcp" rel="nofollow">http://www.youtube.com/watch?v=7MYQicokwmY&amp;feature=plcp</a> I am reviewing this requirement.As per requirement we have to build touch detection like in video link for Android enabled Tablets.</p>

<p>In that video toys (toys with circular, star or rectangle shape) uses Conductive Silicone Sensors with that they are detecting touch on screen &amp; deciding shape of external world object like triangle,circle or a star &amp; further processing the shape.</p>

<p>I have to use same touch detection for android tablets.Can anybody help me to find the way to implement this on Android platform ? Is there any API or framework to implement it?</p>
