DESCRIPTION:The OpenGazer project has recently been revived! OpenGazer is 
 an open source application that tracks a user’s gaze directly from webca
 m images in real-time. The final goal is to write in Dasher using  only on
 e's eyes.  I will discuss work in progress on two problems that we are try
 ing to solve:\n\n1) A binary gesture switch: Here the problem is to learn 
 “yes” and “no” gestures from facial images captured from an ordina
 ry webcam. The learning is done in a short setup phase\, after which these
  signals are automatically detected.  I will show some preliminary results
 . We hope that this switch can be used as a communication device for patie
 nts  with locked-in syndrome.\n\n2) Robust head pose estimation: Here the 
 problem is to control a mouse cursor with one’s head. Again\, there is a
  short training phase involved (specific to the user)\, after which a regr
 ession algorithm computes the corresponding cursor coordinates.
