This study examined how viewers' video watching was affected by the impact the display of video content on an L-shaped news ticker that shows textual information in the margin of a TV screen. By establishing video replay conditions using the L-shaped ticker and the normal screen, we analyzed the viewer's gaze fixation, and their sense of comprehension and degree of recall of the video contents. Differences in the distribution of fixation durations between the two conditions were confirmed; indicating that viewing video on the L-shaped ticker rather than on the normal screen decreased the frequency of longer fixation durations and shortened the total fixation durations when viewing video. No difference was observed in the sense of comprehension and degree of the video contents between the two conditions. Based on these findings, we discussed the possible effects of L-shaped news tickers on viewers' video recognition and the application of the results.
