摘要
视频生动形象的直观画面深受聋人喜爱,但由于聋人的听力受损,使得聋人对视频的信息处理面临诸多困难,无法有效接收、理解视频内容。为此,文章以聋人的自适应学习需求为导向,确定了包括数据处理、用户定位、字幕匹配和无障碍字幕呈现四个环节的聋人视频无障碍字幕设计流程。同时,文章介绍了两个典型的聋人自适应学习场景:面向聋人的交互式视频资源平台和人工智能技术支持的聋童识字阅读,并分别提出了相适的无障碍字幕设计方案。进行基于自适应学习需求的聋人视频无障碍字幕设计,不仅有利于提升聋人的学习兴趣并有效、完整地接收视频信息,而且在一定程度上促进了聋人的教育公平。
The vivid intuitive pictures of video are deeply loved by deaf people. However, deaf people face many difficulties in the information processing of video and cannot receive and understand video content effectively, due to hearing impairment. Therefore, oriented to the adaptive learning needs of deaf people, this paper determined the design flow of video barrier-free subtitles for deaf people, which included data processing, user positioning, subtitle matching and barrier-free subtitles presentation. Meanwhile, two typical adaptive learning scenarios for deaf people were introduced: interactive video resource platform for deaf people and literacy reading for deaf children supported by artificial intelligence technology, and appropriate design programs of barrier-free subtitles were put forward, respectively. The design of video barrier-free subtitles for deaf people based on adaptive learning needs was conducive to improving the learning interests of deaf people, effectively and completely receiving video information, and promoting education equity to some extent for deaf people.
