Eye movements as implicit relevance feedback

Reading detection is an important step in the process of automatic relevance feedback generation based on eye movements for information retrieval tasks. We describe a reading detection algorithm and present a preliminary study to find expressive eye movement measures. Keywords Eye tracking, relevance feedback, reading and skimming detection, relevance prediction General Terms Algorithms, Experimentation, Measurement ACM Classification Keywords H.5.2 [User Interfaces]: Input devices and strategies
