A Personal Word-Hiding Video Caption System on English Vocabulary Learning for Elementary School Students

English is the most important international communication tool in the word. How to teach students to learn English in Non-English speaking countries is always a major task for education. Today, learning for fun and learning from life experience would be a better policy for learning English, especially for children. For the reason that, video is a good media suitable for learning languages, which can record real life situations and can be easily clicked-through via a browser on the Internet, i.e., Youtube. But, when the student watches an English video with caption, the student would be interfered by the pop-up caption since the words in caption are familiar. On the other hand, the caption is closed for watching a video, which may results in heavy cognitive load of learning for the student when most of the words in caption are unfamiliar. Therefore, in this paper, we proposed a new mechanism, called Personal Word-Hiding English Vocabulary Learning System, which can be embedded into a video-browser and automatically hide English words for students involved in the video caption when the students watches English Video through a Browser on the Internet.
