Eye movement of six subjects was recorded as they watched video segments with and without captions. It was found that the addition of captions to a video resulted in major changes in eye movement patterns, with the viewing process becoming primarily a reading process. Further, although people viewing a specific video segment are likely to have similar eye movement patterns, there are also distinct individual differences present in these patterns. For example, someone accustomed to speechreading may spend more time looking at an actor's lips, while someone with poor English skills may spend more time reading the captions. Finally, there is some preliminary evidence to suggest that higher captioning speed results in more time spent reading captions on a video segment.  相似文献

The eye movements of 23 deaf subjects, ages 14 to 61 years, were recorded 30 times per second while the subjects watched four 2.5-minute captioned television programs. The eye movement data were analyzed to determine the percentage of time each subject actually looked at the captions on the screen. It was found that subjects gazed at the captions 84% of the time, at the video picture 14% of the time, and off the video 2% of the time. Age, sex, and educational level appeared to have little influence on time spent viewing captions. When caption speed increased from the slowest speed (100 words per minute, or wpm) to the fastest speed (180 wpm), mean percentage of time spent gazing at captions increased only from 82% to 86%. A distinctive characteristic of the data was the considerable variation from subject to subject and also within subjects (from video to video) in regard to percentage of time spent gazing at captions.  相似文献

The Logical Uncertainty Principle is re-examined from the point of classical logic. Two interpretations are given, an objective one in terms of an axiomatic theory of information, and a subjective one based on Ramsey's theory of probability.  相似文献

ABSTRACT

In response to the Covid-19 pandemic, on 18 March 2020, Prime Minister Boris Johnson announced the immediate closure of schools in England. (The closure was not absolute: schools would remain open for vulnerable children and the children of key workers. In practice, though, very few children have continued to attend.) In what follows, nine English teachers reflect on their experience of teaching under lockdown.  相似文献
