Eye Tracking in Educational Games Environment: Evaluating User Interface Design through Eye Tracking Patterns

Eye tracking research has been commonly used in human computer interaction study. Researcher can collect data on user's behavior through their eye movement by using eye tracking technique. Many company or individual has taken this technology for overcome usability issues in their website, application as well as games. It is not easy to design and develop educational game application. Many aspects must be considered in making a good game. Educational game needs to have good usability in order to be effective and easy to learn. In this paper, we analyze of eye tracking patterns (heat map and gaze plot) to evaluate user interface design in educational game. In addition, we proposed a user interface design guidelines to the issues that highlighted. We conducted experiments using Tobii T60 remote eye tracking system and ManGold software suite to capture and analyze the user's experience when playing educational game. The findings suggest eye-tracking patterns consist of a series of metrics, such as 'number of fixations' and 'heat map separation' correlating with the user interface design issues and ineffective presentation.
