Class Recognizer

java.lang.Object
  java.lang.Thread
      ch.claudio.pen.Recognizer

All Implemented Interfaces:

PenListener, java.lang.Runnable

public class Recognizer
extends java.lang.Thread
implements PenListener

This class or its helpers analyze permanently the ink store to find features. This can be letters or graphical contructs (circle rectangle etc.) or gestures which translate into commands. Everytime a new "dot" is reported and also after some time has expired since the last new dot the central recognizer() method is called to inspect the ink store. Besides that it tries to determine the probable "orientation" of the device.
