We organize a PASCAL EU Network of Excellence challenge for
inferring relevance from eye movements, beginning 1 March 2005. The
aim of this paper is to provide background material for the
competitors: give references to related articles on eye movement
modelling, describe the methods used for extracting the features
used in the challenge, provide results of basic reference
methods and to discuss open questions in the field.
This work was supported by the Academy of Finland, decision
no. 79017, and by the IST Programme of the European
Community, under the PASCAL Network of Excellence, IST-2002-506778.
