The paper I recently presented in Savannah, GA during Eye-Tracking Research and Applications ETRA, was recently published in the ACM digital library.

This paper presents an algorithm that detects misunderstandings in collaborative work at a distance. It analyses the movements of collaborators’ eyes on the shared workspace, their utterances containing references about this workspace, and the availability of ‘remote’ deictic gestures. This method is based on two findings: 1. participants look at the points they are talking about in their message; 2. their gazes are more dense around these points compared to other random looks in the same timeframe. The algorithm associates the distance between the gazes of the emitter and gazes of the receiver of a message with the probability that the recipient did not understand the message.
