Abstract

A method for organizing messages received and transmitted between at least two computer systems over a network and a system configured to implement the method are described. In one aspect, the method includes tracking where a user is gazing as the user is composing an outgoing message on a first computer system. During a composition time period in which the user is composing the outgoing message, a relevance rating for each of a plurality of gaze areas is determined. Each gaze area is associated with one of a plurality of messages displayed by the first computer system, and the relevance rating of a gaze area is based on a number of times the user'"'"'s gaze dwells on the displayed message associated with the gaze area after the user'"'"'s gaze is directed away from the displayed message. The method further includes identifying at least one displayed message that is related to the outgoing message based on the relevance ratings of each gaze area, and associating an identifier for each related message with the outgoing message.
