               technology, it has been widely used in psychology, medicine, advertising, human-computer
               interaction and other fields. At present, the application of eye-tracking technology in the field of
               information retrieval is also a frontier topic. Interactive Information Retrieval (IIR) has a strong
               interdisciplinary nature, involving psychology, sociology, computer science and other fields. It
               is beneficial to use eye-tracking technology to better understand the motivation and mechanism
               of information seeking behavior. Although some studies have sorted out the application of eye
               tracking technology in the field of Library and Information Science, they have not yet elaborated
               on the application of eye tracking technology in IIR and these studies only pointed out a general
               overview of eye tracking measurement indicators and the combination of eye tracking and other
               methods. The purpose of this paper is to expound the application of eye tracking technology in IIR
               as comprehensively as possible, and put forward the prospect of the research trends of eye tracking
               technology in IIR.
                 The literatures used in this paper mainly come from databases such as WoS, ACM, Springer,
               Elsevier, Emerald, IEEE and CNKI. All of the selected literatures are closely related to IIR, the
               main method of which is eye-tracking. The retrieval methods of English documents are (“interactive
               information retrieval” or “information retrieval” or “information search behavior” or “information

               seeking behavior” or “web search”) * (“eye-tracking”), and Chinese documents are (“交互式
               信息检索”or“信息检索行为”or“信息搜索行为”or“信息搜寻行为”or“网页搜索
               行为”).
                 Through reviewing the related researches, four findings can be concluded: 1) Eye-tracking
               devices used in the research of IIR can be divided into three types: remote eye-tracker, head-
               mounted eye-tracker and open resources; 2) Eye-tracking analysis indicators commonly
               used in IIR research can be divided into two categories: functional identification indicators
               (i.e. indicators inferring that stimulate materials can be noticed, found and recognized by the
               subjects) and emotional identification indicators (i.e. indicators that reflect the emotional and
               cognitive state of the subjects to stimulate); 3) Eye-tracking is often used in combination with
               other methods, including three patterns: Eye-mouse collaboration model, Eye-NP collaboration
               model and Eye-cognition collaboration model; 4) Four research topics about eye-tracking in IIR
               are identified: the factors that influence the information search behavior, the browsing behavior
               on SERP, implicit relevance feedback on SERP and the prediction and recommendation on
               SERP.
                 Based on the findings above, an eye-tracking-based interactive information retrieval model is
               constructed. Meanwhile, three limitations of the current work are pointed out, including: there is a
               lack of in-depth study on the factors affecting IIR, such as individual characteristics, memory load
               and cognitive style and so on; most studies focus on the application of eye-tracking technology
               in desktop, lacking of the application in mobile; most eye-tracking studies are performed in the
               controlled laboratory, and there is a lack of IIR research performed in real environment. In view of
               the current limitations, we propose four research trends of eye-tracking research in IIR, including:
