Eye-Tracking to Enhance Usability: A Race Game

Abstract

An important field of research in human-computer interaction studies is the usability of computer games. This paper provides brief definitions of human-computer interactions and usability, and also describes the relevance of these interactions to computer games. Design decisions concerning game elements such as graphical user interface, feedback messages, position and the colour of functional buttons located on the game screen play an important role in identifying the usability and playability of computer games. This study uses eye-tracking technology in order to record eye movements to focus the action of "seeing", which reflects the inner world of humans. A managerial racing game was chosen as an example to analyse its usability. In this context, the design of the social race game was reviewed by recording eye movement data of the participants. The results of eye-tracking data were supported by user comments, which were finally used to improve the design and usability features of the game.
