With the development of technology, the application of eye tracking technology in landscape research has gradually increased, which provides a more objective evaluation method for landscape visual evaluation research. Eye tracking was mainly used in advertising evaluation and reading research in the early stage. It has been gradually introduced in design psychology, cartography, driving, multimedia courseware design, geography and living environment in recent years. At present, researchers have applied eye tracking to landscape visual assessment. By recording people’s observation of the landscape environment objectively, the visual experience and cognitive process of human eyes are quantified, so that the subjective feelings of evaluators can be objectively reflected through eye movement indicators. Compared with the verbal reports of participants, eye tracking technology is more objective, with the advantages of quantitative research and direct evaluation. It is a powerful tool in landscape research. This paper purposes to summarize and prospect the application, general application characteristics, limitations and trends of eye tracking technology in landscape research on the basis of reviewing relevant research literature. This article uses the CiteSpace visual atlas analysis tool, based on 127 English literatures from Web of Science database and 88 Chinese literatures from CNKI, to visualize and quantitatively analyze the status and trends of eye movement research in the landscape, assisted with qualitative analysis. To summarize the research findings: eye movement research began in 2003, and such research in China has been started relatively late, with a large number of studies focused between 2013 and 2020. In landscape research, eye tracking technology is currently mainly used in the field of landscape aesthetics, practical effects and healing effects. Researches on aesthetic effects mainly focus on building a subjective evaluation system of landscape visual quality by combining eye movement with subjective evaluation, use eye tracking technology to analyze the participants’ visual behavior and landscape quality, and then infer the influence of the landscape space or its components on the landscape quality; practical effects pursue the satisfaction of people’s needs for familiarity, viewing, and use of scenery, and related research focuses on wayfinding, tourism resources and map use; the healing effect focuses more on the adjustment of the individual’s physical and mental health,with eye tracking technology generally combined with questionnaires and scales to explore the relations between environmental components and individual behavioral psychology. This paper sorts out the existing eye movement research in the landscape field, and summarizes the general characteristics of eye movement research in the landscape from three aspects: participants, experimental materials, and eye movement indicators. In eye movement research, experimental design is particularly important. The results have an important relationship with the choice of participants, experimental materials and eye movement indicators. Due to the complexity of the experiment, college students are usually selected as participants, and the number is about 30. Experimental materials include static stimulus, dynamic stimulus and real environment. The three stimulus materials have their own advantages and disadvantages. From the feasibility of current research and the systematic perspective of data interpretation, static stimulus materials are the most widely used. Dozens of eye movement indicators have been used in various studies. Among them, commonly used eye movement indicators include fixation indicators, saccade indicators, and pupil indicators. At present, the application of eye tracking technology in landscape research still has certain limitations. In order to ensure the scientificity of eye movement research, the scientific and rigorous aspects of eye movement data extraction, interpretation and experimental process control should be further promoted. The base number and selection range of the participants should be expanded, making the samples diverse. Combining with cognitive psychology testing methods, strengthening the coordination of eye movement and other physiological sensor technologies, and conducting multi-sensory comprehensive evaluation in the landscape field will help to better explore and explain the relationship between “human-space-perception”. The application of eye tracking technology to quantify and explore people’s in-depth perception of the landscape environment, to enhance the credibility of landscape evaluation using objective data, and to improve the quality of the landscape, is bound to get more attention and recognition in landscape design and optimization. Eye tracking will also become an irreplaceable method and tool in landscape visual evaluation. It is believed that with the development of research, eye tracking technology will be more widely used in the landscape field, and more in-depth and systematic research will be completed.
