PolyRec is a unistroke gesture recognizer suitable for fast prototyping of gesture-based applications. The recognizer uses a nearest neighbor approach, and requires a small number of samples for each class.

The similarity between two gestures is calculated through a three steps procedure:
-firstly, each gesture is approximated to a polyline, in order to extract its main movements;
- then, the two polylines are aligned to obtain an equal number of segments from both of them;
- lastly, the distance is found by summing the contribution of each pair of segments.

This implementation is a prototype developed for scientific purposes. More technical details on PolyRec can be found in the following scientific paper:
