Online games have been attracting a lot of users' attention. It is highly impressed that the users are engaged in the game world. Applying online games to help students learn has been a controversial issue. In this study, seven undergraduate students were asked to read Chinese texts, solve math problems, and identify differences between two nearly identical pictures with their eye movement recorded with an eye tracker (FaceLab4.5). The preliminary result indicated that the game playing scale of the subjects was somewhat positively correlated with the overall eye fixation counts in Chinese text reading and math problem solving, but the opposite was found in comparing two pictures. More findings regarding how the subjects' game playing duration and frequency influenced their abilities in reading texts and viewing pictures were further discussed.
