In the interactive video, as the user's memory blurs executive list and forgets, the user may repeat the operation, resulting in the subsequent user experience cannot be optimized. The construction of context lines helps reduce the probability of repeated executive list operations by users. In this article, the author introduces and analyzes the context of interactive video, let's take a look. I. Introduction This article mainly introduces one of the important functions of interactive video: context lines. In order to facilitate understanding, In the story, the eldest brother built a straw executive list house, the second brother built a wooden house, and the third brother built a brick house. In the end, only the third brother's house was not destroyed by the wolf. The three brothers also worked together to get the wolf into the pot and eat the big bad wolf. This is a story that some of us are familiar with, and not only the version of "pigs eat wolves", but also versions such as "wolves eat pigs, a clever plan to drive away the big executive list bad wolf", etc., are also widely circulated. The Context of Interactive Video" We try to treat executive list the multi-dimensional possibilities of interactive video content as different parallel worlds , and it is easy for people to get lost and confused before entering and repeatedly jumping several times. For example, in the story, the more behaviors the pig may have, the more parallel worlds will be generated executive list accordingly. Because the world line is no longer developed in a single line, more content information and more possibilities also form information pressure on users.
