I have a touch display. As input I can receive the coordinates and how many touch points are in use, basically I just get an X,Y couple for every touch event/activated point at a customizable rate.
I need to start from this and build my own callback system to achieve something like Object.onUp().doSomething() meaning that I would like to abstract just the detection of some particular movements and not having to deal with raw data: what algorithms can be useful in this case? What statements? Is there some C++ library that I can dissect to get some useful info?
Would you suggest the use of an heuristic algorithm?
