Purpose This paper aims to examine the effect of domain knowledge on eye-tracking measures and predict readers’ domain knowledge from these measures in a navigational table of contents (N-TOC) system. Design/methodology/approach A controlled experiment of three reading tasks was conducted in an N-TOC system for 24 postgraduates of Wuhan University. Data including fixation duration, fixation count and inter-scanning transitions were collected and calculated. Participants’ domain knowledge was measured by pre-experiment questionnaires. Logistic regression analysis was leveraged to build the prediction model and the model’s performance was evaluated based on baseline model. Findings The results showed that novices spent significantly more time in fixating on text area than experts, because of the difficulty of understanding the information of text area. Total fixation duration on text area (TFD_T) was a significantly negative predictor of domain knowledge. The prediction performance of logistic regression model using eye-tracking measures was better than baseline model, with the accuracy, precision and F(β = 1) scores to be 0.71, 0.86, 0.79. Originality/value Little research has been reported in literature on investigation of domain knowledge effect on eye-tracking measures during reading and prediction of domain knowledge based on eye-tracking measures. Most studies focus on multimedia learning. With respect to the prediction of domain knowledge, only some studies are found in the field of information search. This paper makes a good contribution to the literature on the effect of domain knowledge on eye-tracking measures during N-TOC reading and predicting domain knowledge.

Text Information

In China in recent years, the rental housing market has boomed, but insufficient attention has been paid to microsubject tenants in the market, and there is a lack of research results on tenants’ decision-making processes. In keeping with the characteristics of China’s accommodation-renting population, this study takes as its research object graduating students, who form an important group in the housing rental market, and focuses on the information retrieval process underlying prospective tenants’ rental decisions. First, it investigates tenants’ concerns during the renting process by means of questionnaires. Second, using eye-tracking experiments, the real online renting process is simulated and tenants’ web listings are analyzed qualitatively and quantitatively. In the process of information search, the characteristics and rules of browsing the entry search page, the listings page, and the details page are obtained, and the factors that prospective tenants pay attention to in their search for rental information are obtained. The research results show that initial alphabetical sorting of the term search page can improve the subjects’ efficiency in locating the target keywords, the text information display area of the listings page receives more attention than others, and the real concern factors of the tenants on the page listing details are generally consistent with their selected factors but deviate slightly. Finally, the layout and display of web page information affect how subjects’ attention is distributed, and web page information presents a significant difference in attention between upper and lower pages.

Purpose The purpose of this paper is to introduce eye tracking as a method for capturing direct and indirect measures of online human information search behaviour. The unique contribution of eye-tracking data in studying information behaviour is examined in the context of health information research. Design/methodology/approach The need for multiple methods of data collection when examining human online health information behaviour is described and summarised. The nature of human eye movements in information use and reading is outlined and the emergence and application of contemporary eye-tracking technology are explained. Findings The paper summarises key contributions and insights that eye tracking has provided across multiple studies, with examples of both direct data on fixations and gaze durations as well as theoretical assessments of relevance and knowledge gain. Originality/value The paper provides a basic introduction to the application of a unique method for information research in general and online health information search in particular and provides readers with an awareness of how such data are captured and interpreted.

The extensification activities of Education Informatics Network use in Turkey are in progress. The use and preferability of this education portal by teachers and students depend on various factors. One of these factors is usability. The purpose of this research is to make the usability analysis of the Education Informatics Network from the perspective of secondary school students. The participants of the study consist of 10 students who are from secondary school where the Movement of Enhancing Opportunities and Improving Technology is carried out. The data of the study were obtained from the eye-tracking method in the completion process of the authentic tasks given to the students and from the survey that was used to determine the demographic information. The results of the study show that the students completed the authentic task with success and they are able to reach the search results accurately and rapidly.   Keywords: Education informatics network, FATIH project, usability, eye tracking, information search behavior, secondary school students, human–computer interaction, interface design.

Areas Of Interest

Using eye-tracking, this study investigates fixation duration of students viewing pictures of pigs, which systematically vary in the facial expression of the pig and in the barn setting. The aim of this study is to analyze which picture elements are viewed and for how long, as well as how fixation times vary with a change of the expression of the pig and the barn type. The results show clear effects of picture composition: pig expression and pen type affect fixation durations of different areas of interest with the influence of the pig being considerably larger. Face regions are viewed longer in the “happy” pig, while floor/bedding and the eyes are viewed longer in pictures showing the “unhappy” pig which might be a hint for information search. The power of facial expressions, also for the depiction of farm animals, is a new finding of this paper, which might be of importance when selecting agricultural pictures for different purposes.
