Eye-gaze based interest awareness

In many situations, the amount of information that can be given to a receiving party exceeds practical constraints such as the time available for the information exchange, motivational limitation on the receiving party, or the maximum complexity that the receiving party is willing to process. A typical example of this situation is a professional, educated museum guide touring an interested party of art novices through a museum. The guide has access to much more knowledge that the party can handle, so she has to limit the information given during the tour. Based on the perceived interests of the party, the guide can adapt her tour, selecting from her extensive knowledge of the works exhibited in the museum, to better align the relayed information to the interests of the party.
This project will address the question of how to use eye-tracking data in extracting the interests of a user from her eye movements. In a previous project (described by Janssen, 2006; Van Maanen, Janssen, & Van Rijn, 2006), we built a Virtual Museum Guide (VMG) that commented on the presented art works based on the eye fixations of the visitor. The VMG only gave background information on the depicted objects or persons if users fixated on them.
However, from the eye movements literature it is known that people do not have voluntary control over their eye movements (Theeuwes, 1992). Usually, control of eye-movements is divided into a voluntary component and a stimulus-driven component (Henderson, 2003). That is, eye movements can be caused by salient features of the art works. In this project, we will adapt the existing Virtual Museum Guide to discount for the involuntary eye movements.
