DESCRIPTION (provided by applicant): The proposed project will develop an innovative Internet technology - the Descriptive Video Exchange (DVX) - to facilitate research into the effectiveness of amateur video description for the blind and visually impaired. Video accessibility is a critical and growing issue in the rehabilitation of the blind and visually impaired, and has impacts in education and employment, as well as entertainment and social integration. Professional video description requires careful scripting and recording of brief voiceover segments announcing on-screen events that would otherwise be inaccessible to the blind and visually-impaired. Video description has been shown to make educational and entertainment video more effective for blind and visually-impaired viewers, but it is extremely costly and time-consuming. With the accelerated production of video materials and dwindling funding to support professional description, it is increasingly important to investigate the effectiveness and viability of a volunteer-based system of video description. DVX will provide a platform for the simple creation, sharing, viewing, and evaluation of descriptions of DVD and Internet-based video content recorded by volunteers, and evaluated by people with a wide range of visual disabilities. DVX will be the first system to tightly couple video description recording and playback tools with a server-based, description-sharing mechanism, thus making the creation and consumption of the described materials seamless for both volunteers and blind consumers. The availability of DVX will make it possible to address several important research questions about the effectiveness of using amateurs to describe video. We propose several specific research questions; however DVX opens the possibility for many more future video description studies. The present project proposes to conduct the following investigations utilizing an Internet-based survey protocol involving 50 sighted amateur describers and 200 evaluation participants with a broad range of visual disabilities: 1. Evaluate the effectiveness of amateur description for a variety of genres and video formats, in comparison to traditional, professional video description. In addition, evaluate the influence of consumer feedback on the quality of amateur description. 2. Evaluate the effectiveness of a proposed set of Enhanced Playback Functions intended to mitigate problems commonly encountered in amateur description; 3. Conduct preliminary research into the use of mainstream social networking platforms (e.g., Facebook and Twitter) for the recruitment of amateur describers. PUBLIC HEALTH RELEVANCE: The limited accessibility of most video materials is a critical and growing issue in the rehabilitation of the blind and visually impaired, and has negative impacts on their education and employment, as well as entertainment and social integration. The proposed project will develop an innovative Internet technology - the Descriptive Video Exchange (DVX) - to facilitate research into the effectiveness of using amateur describers to boost the availability of accessible video for the blind and visually impaired. With the accelerated production of video materials and dwindling funding to support professional description, it is increasingly important to investigate the effectiveness and viability of a volunteer-based system of video description.

描述（由申请人提供）：拟议的项目将开发创新的互联网技术 - 描述性视频交流（DVX） - ，以促进对盲人和视觉障碍的业余视频描述有效性的研究。视频可访问性是盲目和视力障碍的康复，对教育和就业以及娱乐和社会融合产生影响的关键和日益严重的问题。专业视频描述需要仔细的脚本编写，并记录简短的配音片段，以宣布屏幕上的事件，否则这些事件将无法访问盲人和视觉上受损。已显示视频描述使教育和娱乐视频对盲人和视觉障碍的观众更有效，但它非常昂贵且耗时。随着视频材料的加速生产和资金减少以支持专业描述，研究基于志愿者的视频描述系统的有效性和生存能力越来越重要。 DVX将为简单创建，共享，查看和评估DVD和基于Internet的视频内容的简单创作，评估和评估，并由志愿者记录的基于Internet的视频内容，并由具有广泛视觉残疾的人进行评估。 DVX将是第一个与基于服务器的描述共享机制进行紧密磨练的视频描述和播放工具的系统，从而使志愿者和盲人消费者的无缝材料的创建和消耗。 DVX的可用性将使有关使用业余爱好者描述视频的有效性解决一些重要的研究问题。我们提出了一些具体的研究问题；但是，DVX为更多未来的视频描述研究打开了可能性。本项目提议利用基于互联网的调查协议进行以下调查，涉及50种视觉业余描述者和200名具有广泛视觉障碍的评估参与者：1。与传统，专业视频描述相比，评估各种流派和视频格式的业余描述的有效性。此外，评估消费者反馈对业余描述质量的影响。 2。评估一组提议的增强播放功能的有效性，该功能旨在减轻业余描述中常见的问题； 3.对主流社交网络平台（例如Facebook和Twitter）的使用进行初步研究，以招募业余描述。 公共卫生相关性：大多数视频材料的可访问性有限，是盲人和视力障碍的康复中的一个关键和日益严重的问题，对其教育和就业以及娱乐和社会融合产生负面影响。拟议的项目将开发创新的互联网技术 - 描述性视频交流（DVX） - ，以促进研究使用业余描述者来提高盲人和视觉障碍的可访问视频的有效性。随着视频材料的加速生产和资金减少以支持专业描述，研究基于志愿者的视频描述系统的有效性和生存能力越来越重要。
