摘要

音频描述可以使视障人士能够理解视频中的视觉内容。然而,大多数在线视频缺乏音频描述,部分原因是缺乏能够创建高质量描述的专家。我们介绍了ViScene,这是一个基于网络的创作工具,它可以利用更多的视力正常的非专家来帮助他们通过两种反馈机制——简洁的可视化和专家的评论——生成高质量的描述。通过一项有N = 6名参与者的混合设计研究,我们探讨了ViScene的可用性以及有和没有反馈意见的视力非专家创建的描述的质量。我们的研究结果表明,非专家可以用反馈意见做出更好的描述;初步的见解也强调了有视觉障碍的人在提供这种反馈方面可以发挥的作用。

ViScene: A Collaborative Authoring Tool for Scene Descriptions in Videos.

Audio descriptions can make the visual content in videos accessible to people with visual impairments. However, the majority of the online videos lack audio descriptions due in part to the shortage of experts who can create high-quality descriptions. We present ViScene, a web-based authoring tool that taps into the larger pool of sighted non-experts to help them generate high-quality descriptions via two feedback mechanisms-succinct visualizations and comments from an expert. Through a mixed-design study with N = 6 participants, we explore the usability of ViScene and the quality of the descriptions created by sighted non-experts with and without feedback comments. Our results indicate that non-experts can produce better descriptions with feedback comments; preliminary insights also highlight the role that people with visual impairments can play in providing this feedback.
