Eye Tracking

o Effects of eye movements on the flow of information during free-viewing


   It is commonly believed that the primary purpose of  eye movements is
   to increase the information flow through the center of gaze.  In this
   paper  we  directly  test  the  influence  of  eye  movement  on  the
   information flow  to  the  brain  by  recording  eye positions during
   free-viewing  videos   of   natural   activities  and  quantitatively
   analyzing the resulting visual input.  The recorded eye positions are
   used  to  derive  the  gaze-centered  time-varying  images  from  the
   original video.  The statistical properties of  the resulting images,
   in particular, the temporal correlations  are analyzed systematically
   and are used to verify quantitatively  that  the  information flow at
   the center of gaze  is  dramatically  increased  due  to saccadic eye
   movements, on a time scale longer than saccade interval.
