Does anyone know a good touch pattern recognition library? How is it generally done? I would like to have the entire IOS device as an input device. For example, if someone draws a big heart on the screen, we are going to the favorites page. Somehow I need to know someone drew a big heart on the screen.
Thanks,
Ross
I found a MultistrokeGestureRecognizer library on GitHub that looks promising. Looks like its a matter of running the Shape Editor and exporting the strokes as a JSON array of points. This should be enough to get you started.
If you need more resources I would take a look at the two WWDC videos on gesture recognizers from 2010 as mentioned in this SO answer.
Here’s a link to the 2011 WWDC multi-touch video which may be of some help to you also.
