Class PenStreamingConnection

java.lang.Object
  edu.stanford.hci.r3.pen.streaming.PenStreamingConnection

public class PenStreamingConnection
extends java.lang.Object

This class reads from a COM port (connected to a Bluetooth transceiver). It streams data from the Nokia SU-1B pen and converts it according to the Nokia Document. The idea for this class is that it reports low-level pen events. It does not do any bit of gesture recognition.
