DESCRIPTION:Humans involuntarily move their eyes when retrieving an image 
 from memory. This motion is often similar to actually observing the image.
  We suggest to exploit this behavior as a new modality in human computer i
 nteraction\, using the motion of the eyes as a descriptor of the image. In
 teraction requires the user's eyes to be tracked but no voluntary physical
  activity. We perform a controlled experiment and develop matching techniq
 ues using machine learning to investigate if images can be discriminated b
 ased on the gaze patterns recorded while users merely think about image. O
 ur results indicate that image retrieval is possible with an accuracy sign
 ificantly above chance. We also show that this result generalizes to image
 s not used during training of the classifier and extends to uncontrolled s
 ettings in a realistic scenario.
