@javispedro I haven't found any occurrence of this kind of patents being enforced in Europe. Do you know of any ?

@droll Levenstein distance is good for spelling mistakes if you can get individual keystrokes. In case of a "swype"-like keyboard it does not work (IMO) because it's not possible to isolate individual strokes.

The current algorithm is based on geometric properties of the curve drawn. It walks through the tree of all possible words (with scoring & heuristics applied very soon to trim the candidates tree) and try to assign a score to every possible word based on properties showing user "intention" (distance to key, speed, sharp turns ...).

@matimilko for the moment weather is on your side
