edu.stanford.hci.r3.pen
Class PenSimulator

java.lang.Object
  edu.stanford.hci.r3.pen.PenInput
      edu.stanford.hci.r3.pen.PenSimulator

All Implemented Interfaces:

java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.util.EventListener

public class PenSimulator
extends PenInput
implements java.awt.event.MouseListener, java.awt.event.MouseMotionListener

Opens a JFrame/JPanel that the user can draw on with his mouse or Tablet stylus. This will simulate a digital pen. We can make the pen activate by holding the left mouse button down.

This also contains a simple r-theta based ink simplification algorithm. Basically, if the distance of the current point is sufficiently far from the last two points, in terms of distance (r) or direction (theta), then we trigger a new pen sample. This algorithm might be applied to actual pen input in the future, to achieve ink simplification/beautification, etc.

Method Detail

addLivePenListener

public void addLivePenListener(PenListener penListener)

Description copied from class: PenInput

Adds a low-level pen data listener to the live pen. You SHOULD call this after starting live mode.... However, we can cache the listener for you, if you really want. This is to eliminate annoying ordering constraints. Subclasses *should* override this, and call the super, to actually make use of PenListeners.

Overrides:

addLivePenListener in class PenInput

mouseClicked

public void mouseClicked(java.awt.event.MouseEvent e)

Specified by:

mouseClicked in interface java.awt.event.MouseListener

mouseDragged

public void mouseDragged(java.awt.event.MouseEvent e)

Specified by:

mouseDragged in interface java.awt.event.MouseMotionListener

mouseEntered

public void mouseEntered(java.awt.event.MouseEvent arg0)

Specified by:

mouseEntered in interface java.awt.event.MouseListener

mouseExited

public void mouseExited(java.awt.event.MouseEvent arg0)

Specified by:

mouseExited in interface java.awt.event.MouseListener

mouseMoved

public void mouseMoved(java.awt.event.MouseEvent arg0)

Specified by:

mouseMoved in interface java.awt.event.MouseMotionListener

mousePressed

public void mousePressed(java.awt.event.MouseEvent e)

Specified by:

mousePressed in interface java.awt.event.MouseListener

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent e)

Specified by:

mouseReleased in interface java.awt.event.MouseListener

removeLivePenListener

public void removeLivePenListener(PenListener penListener)

Description copied from class: PenInput

Removes the pen listener from the live pen. Subclasses *should* override this, and call the super's implementation if necessary, to actually make use of PenListeners.

Overrides:

removeLivePenListener in class PenInput

startLiveMode

public void startLiveMode()

Specified by:

startLiveMode in class PenInput

stopLiveMode

public void stopLiveMode()

Specified by:

stopLiveMode in class PenInput
