Processing Written Language in Video Games: An Eye-Tracking Study on Subtitled Instructions.

Written language is a common component among the multimodal representations that help players construct meanings and guide actions in video games. However, how players process texts in video games remains underexplored. To address this, the current exploratory eye-tracking study examines how players processed subtitled instructions and resultant game performance. Sixty-four participants were recruited to play a videogame set in a foggy desert, where they were guided by subtitled instructions to locate, corral, and contain robot agents (targets). These instructions were manipulated into three modalities: visual-only (with subtitled instructions only), auditory only (with spoken instructions), and visual-auditory (with both subtitled and spoken instructions). The instructions were addressed to participants (as relevant subtitles) or their AI teammates (as irrelevant subtitles). Subtitle-level results of eye movements showed that participants primarily focused on the relevant subtitles, as evidenced by more fixations and higher dwell time percentages. Moreover, the word-level results indicate that participants showed lower skipping rates, more fixations, and higher dwell time percentages on words loaded with immediate action-related information, especially in the absence of audio. No significant differences were found in player performance across conditions. The findings of this study contribute to a better understanding of subtitle processing in video games and, more broadly, text processing in multimedia contexts. Implications for future research on digital literacy and computer-mediated text processing are discussed.
