Mining eyetracking data to characterise users and theirpatterns of use

Öder, Melih
Eye tracking studies typically collect an enormous amount of data that encodes a lot of information about the users’ behavior and characteristics on the web. However, there are not many studies that mine such data to learn and discover user characteristics and profiles. The main goal of this study is to mine eye tracking data by machine learning methods to create data models which characterise users and predict their characteristics, in particular, familiarity and gender. Detecting users’ characteristics can be used in creating adaptive user interfaces to improve user experience and interaction efficiency. In a typical eye tracking study, collected demographics data have participants’ educational backgrounds, gender, age, and frequency of the web page use. In this thesis, a model focusing on the users’ familiarity degree and gender is first created based on an existing eye-tracking dataset, and then a new eye-tracking study is conducted to validate this model. The main contribution of this thesis is a machine learning approach that can be used to characterise users, in particular, familiarity and gender, based on eye-tracking data and also a tool that can be used to extract features and metrics from an eye-tracking dataset.


Eye Tracking Scanpath Analysis Techniques on Web Pages: A Survey, Evaluation and Comparison
Eraslan, Sukru; Yesilada, Yeliz; Harper, Simon (2016-01-01)
Eye tracking has commonly been used to investigate how users interact with web pages, with the goal of improving their usability. This article comprehensively revisits the techniques that could be applicable to eye tracking data for analysing user scanpaths on web pages. It also uses a third-party eye tracking study to compare these techniques. This allows researchers to recognise existing techniques for their goals, understand how they work and know their strengths and limitations so that they can make an ...
Optimization of an online course with web usage mining
Akman, LE; Akkan, B; Baykal, Nazife (2004-02-18)
The huge amount of information existing in the World Wide Web constitutes an ideal environment to implement data mining techniques. Web mining is the mining of web data. There are different applications of web mining: web content mining, web structure mining and web usage mining. In our study we analyzed an online course by web usage mining techniques in order to optimize the navigation paths, the duration of the time spend on each page and the number of visits throughout the semester of the course. Moreove...
Eye tracking in multimodal comprehension of graphs
Acartürk, Cengiz (2012-07-31)
Eye tracking methodology has been a major empirical research approach for the study of online comprehension processes in reading and scene viewing. The use of eye tracking methodology for the study of diagrammatic representations, however, has been relatively limited so far. The investigation of specific types of diagrammatic representations, such as statistical graphs is even scarce. In this study, we propose eye tracking as an empirical research approach for a systematic analysis of multimodal comprehensi...
A tool for visualization of risk information: the Risk Box
Karakoçak, Elif; Birgönül, Mustafa Talat; Dikmen Toker, İrem; Department of Civil Engineering (2021-6-28)
Visualization is an effective way to represent data that mainly aims to make the data easier to be understood, analyzed, and processed by the users. In literature, there exist many studies focusing on the necessity and effectiveness of visualization in decision-making processes. Risk, on the other hand, is an important topic that needs to be considered for decision-makers in the project to decide on the further pathways to follow and need to be visualized in such a way to aid the decision-makers in these pr...
Examining an Online Collaboration Learning Environment with the Dual Eye-Tracking Paradigm: The Case of Virtual Math Teams
Uzunosmanoglu, Selin Deniz; Çakır, Murat Perit (2014-06-27)
The aim of this study is to investigate the computer supported collaborative problem solving processes using the dual eye-tracking method. 18 university students participated in this study, and 9 pairs tried to solve 10 geometry problems using Virtual Math Team (VMT) online environment. Which situations the participants' eye movements, and eye gazes overlap, and how usability of VMT environment affect the problem solving processes are tried to identify. After experiments with two eye-trackers, a questionnai...
