I am trying to write a game in which the user can issue commands by drawing certain patterns with his fingers ... for example, if he draws a circle, the letter "S", an extract, etc.
I am already familiar with touch events, and I am able to read the coordinates ... my problem is finding algorithms and pattern recognition information with some degree of error ... for example, If I have to find a circle that I have to detect, even if the user isn’t made perfect.
Any resources in this matter, thanks!
