Filling out PDF forms with screen readers has always been a challenge for people who are blind. Many of these forms are not interactive and hence are not accessible; even if they are interactive, the serial reading order of the screen reader makes it difficult to associate the correct labels with the form fields. This demo will present TransPAc[5], an assistive technology that enables blind people to fill out PDF forms. Since blind people are familiar with web browsing, TransPAc leverages this fact by faithfully transforming a PDF document with forms into a HTML page. The blind user fills out the form fields in the HTML page with their screen reader and these filled-in data values are transparently transferred onto the corresponding form fields in the PDF document. TransPAc thus addresses a long standing problem in PDF form accessibility.
对于盲人来说，使用屏幕阅读器填写PDF表单一直是一项挑战。许多此类表单不具有交互性，因此无法访问；即使它们具有交互性，屏幕阅读器的串行阅读顺序也使得难以将正确的标签与表单字段相关联。本演示将展示TransPAc[5]，这是一种辅助技术，可使盲人填写PDF表单。由于盲人熟悉网页浏览，TransPAc利用这一事实，将带有表单的PDF文档忠实地转换为HTML页面。盲人用户使用他们的屏幕阅读器在HTML页面中填写表单字段，这些填写的数据值会被透明地传输到PDF文档中的相应表单字段上。因此，TransPAc解决了PDF表单可访问性方面长期存在的问题。
