Title of Talk: Guiding eye movements for better communication


bstract: Abstract: In this talk I will present an overview of our objective

s and current
results related to gaze-based communication. Our goal is t

o integrate
gaze into visual communication systems by measuring and guid

ing eye
movements. For guidance we first predict a set of about 10 sali

locations. We then change the probabilities for one of these candida

to be attended: for one candidate the probability is increased for

others it is decreased. To increase saliency for example we add re

dots that are displayed very briefly such that they are hardly perceiv

consciously. To decrease the probability we locally reduce the spatia

and/or temporal frequency content. Again if performed in a

ntingent fashion with low latencies these manipulations of the
video re

main unnoticed. Overall the goal is to find that real-time

on of the video which minimizes the difference between the
actual and t

he desired scanpath. Applications are in the area of
vision-based commun

ication (better control of what information is
conveyed) and augmented v

ision (guide a person%92s gaze by the gaze of an
expert or a computer-vi

sion system).
