Determining optimal caption placement using eye tracking

Abstract

In this study, the effect of caption placement on information intake is examined. Eye movement data is used to quantitatively analyze the effect of four different captioning methods. Information intake (i.e. Information Assimilation (IA)) is measured via a 4-category comprehension quiz, developed by S.R Gulliver and G. Ghinea, which measures key differing aspects of captioned videos. Results indicate that caption placement can have significant effects on reading time, number of saccadic crossovers, and ratio of fixations on captions.
