Hi,<p>I'm experimenting or rather gonna be experimenting with some new cool ways to draw things on touch based devices. I wish to conduct a small user experience experiment with iPhone, iPad & iPod touch users. Its a very simple experiment where one is required to draw/trace shapes by dragging their finger. It supports single touch.<p>The app is currently active at http://toucherry.appspot.com/<p>Through this I wish to find out how easy do the user find these simple tasks. I'm hoping to build a better curve editor through this experiment.<p>Thanks
