Our communication is increasingly mediated through the creation and consumption of digital content such as videos, podcasts and myriad forms of social media. Access to digital content has become integral to our social and civic participation in society. Much of this creation and consumption, however, is not equally accessed by all. People with accessibility needs face several challenges in accessing digital content and are therefore at risk of isolation. Accessibility capabilities for digital content are typically viewed through the lens of standards such as subtitles and audio description. While these are helpful for some users, digital content still introduces challenges for many with a range of diverse needs. This proposal aims to explore the design of bespoke accessibility solutions, based on a given individual's exact needs, to support access to digital content. CA11y (Content Accessibility: Highly Individualised Digital Content for Supporting Diverse Needs) proposes a shift in how we consider the provision of accessible digital content. CA11y will envision and develop technologies that allow for highly-responsive content, unique to each individual's accessibility needs. Simultaneous, individual renderings of content will allow us to explore previously unconsidered accessibility solutions. For instance, for users who face challenges with speech, we might limit the background noise in a radio drama to make the actor's voice clearer. We might slow a news ticker to support easier comprehension. We might completely reconfigure content so that scenes with complex dialogue or textual descriptions are removed. Or, finally, we might change the visual contrast of individual onscreen elements (e.g. graphic overlays) to support ease of viewing.The distribution of digital content via the internet, with accompanying metadata, means that content can respond to the end-user's requirements. This may be rendered to an individual's devices or needs, based on some rule-set or ontology. This concept is broadly termed Object-Based Media (OBM). Crucially, OBM enables an entirely individual rending of digital content for each end-user. While the distribution of digital content in such a way has been shown to offer novel exciting, responsive digital content experiences, little work has explored what this can mean for accessibility.The highly individualised digital content afforded by concepts such as OBM provides transformative potential to support those with a range of diverse accessibility needs. CA11y will work with one such group - people with aphasia. Aphasia is a language impairment that affects one-third of stroke survivors. People with aphasia often have a range of complex accessibility needs due to specific challenges with language, notably listening, reading, speaking and writing. This means that they often can no longer engage with digital content, meaning they face a growing digital divide. The aforementioned accessibility standards such as subtitles and audio description do not cater to their needs. In CA11y, people with aphasia will support the co-design of an innovative range of technological prototypes to support their access needs through responsive, individualised digital content. CA11y will act as a radical first step in a new research field that seeks to support those with a range of access needs through highly individualised experiences, with users with aphasia acting as an exemplar for others with accessibility needs.

通过创建和消费数字内容，例如视频，播客和各种社交媒体形式，我们的沟通越来越多地介导。获取数字内容已成为我们社会参与社会的组成部分。但是，大部分创造和消费并非所有人平均访问。具有可访问性需求的人在访问数字内容时面临几个挑战，因此有孤立的风险。通常通过字幕和音频说明等标准镜头查看数字内容的可访问性功能。尽管这些对某些用户很有帮助，但数字内容仍然为许多有多种需求的许多人带来挑战。该建议旨在根据给定个人的确切需求探索定制可访问性解决方案的设计，以支持对数字内容的访问。 CA11Y（内容可访问性：高度个性化的数字内容以支持各种需求）提出了我们考虑提供可访问数字内容的方式的转变。 CA11Y将设想和开发允许高度响应内容的技术，这是每个人的可访问性需求所特有的。同时，内容的单个渲染将使我们能够探索以前未经考虑的可访问性解决方案。例如，对于用语音面临挑战的用户，我们可能会限制无线电戏剧中的背景噪音，以使演员的声音变得更加清晰。我们可能会放慢新闻股票，以支持更容易理解。我们可能会完全重新配置内容，以便删除具有复杂对话或文本描述的场景。或者，最后，我们可能会更改单个屏幕上的元素（例如图形覆盖层）的视觉对比度，以支持易于观看的易于观看。通过Internet和随附的元数据进行数字内容的分布意味着内容可以响应最终用户的要求。这可以根据某些规则集或本体论渲染到个人的设备或需求。这个概念广泛称为基于对象的媒体（OBM）。至关重要的是，OBM为每个最终用户提供了完全个性化的数字内容范围。尽管已经证明，数字内容的分布可提供令人兴奋的，响应迅速的数字内容体验，但很少的工作探讨了这对可访问性意味着什么。OBM等概念提供的高度个性化的数字内容为支持那些具有多种可访问性需求的人提供了变革潜力。 CA11Y将与一个这样的群体合作 - 失语症患者。失语症是影响三分之一中风幸存者的语言障碍。失语症的人通常由于语言挑战，尤其是聆听，阅读，说话和写作，因此通常有一系列复杂的可访问性需求。这意味着他们通常无法再参与数字内容，这意味着他们面临着不断增长的数字鸿沟。上述可访问性标准（例如字幕和音频说明）无法满足其需求。在CA11Y中，失语症的人将通过响应迅速的个性化数字内容来支持一系列创新的技术原型的共同设计，以支持其访问需求。 CA11Y将在一个新的研究领域中充当激进的第一步，该领域旨在通过高度个性化的体验来支持具有一系列访问需求的人，而失语症的用户则是对其他有可访问性需求的人的典范。
