Where do they look at? Analysis of gaze interaction in children while playing a puzzle game

In recent years the usage of video-games in education, therapies and training, has risen sharply. The adaptation of serious games to users' needs may offer new enriching learning environments. Eye tracking sensors collect information about the location and duration of eye movements within a specific area on a computer monitor. This paper presents a usability analysis of users' eye movements while using the set of puzzle games. For this purpose a set of data collected from 63 children with an average age of 9.95 (SD = 1.21) and different attention skills is analyzed during their interaction with a set of puzzle games. Fixation data is extracted and analyzed as regards of where do they look first and most. These resources should be complemented with other interaction records, but they are interesting for creating optimized user interfaces.
