How can the UX of Accessible Services be accurately measured and used to improve the overall experience of using accessible devices?

数字平台被用来为社会所有成员提供信息和服务。随着对技术的依赖，对所有人都可以获得的服务的需求也在增加。然而，可访问性被刻板地视为一种附加服务，因此采用二元方法来创建可访问的解决方案；服务要么可访问，要么不可访问。很难确定哪些产品实现了可访问性，并增加了更易用的好处。无障碍服务不应该被创建得足够好，但应该让参与数字体验的整体体验对最终用户来说似乎是愉快的。我们之前在开发专注于媒体字幕的框架时研究了无障碍用户体验，并随后利用这一点开发了在不同设备上显示字幕内容的可访问和可用的方法。然而，目前还不清楚应该使用哪些因素来总体上理解无障碍产品的用户体验，以及这些因素对最终用户的重要性。在这个博士学位中，我们的目标是回答以下问题：如何准确测量和使用无障碍服务的用户体验，以改善使用无障碍设备的整体体验？

Digital platforms are used to provide information and services for all members of society. With a reliance on technology comes an increase in the demand for services that are accessible by all. However, accessibility is stereotypically viewed as a bolt-on service and as such a binary approach is taken to creating accessible solutions; services are either accessible or not. It is difficult to identify products that achieve accessibility with the added benefit of being more usable. Accessible services should not be created to be 'good enough' but should make the overall experience of participating in a digital experience seem pleasant to the end user.We have previously examined UX within accessibility in the development of a framework that focuses on media subtitles and subsequently used this to develop accessible and usable methods of displaying subtitled content on different devices. However, it is unclear what factors should be used to understand the UX of accessible products in general and the importance that these factors have to end users. In this PhD, we aim to answer the following:How can the UX of Accessible Services be accurately measured and usedto improve the overall experience of using accessible devices?
