摘要

对于盲人来说,用屏幕阅读器填写PDF表格一直是一个挑战。其中许多表单不是交互式的,因此无法访问;即使它们是交互式的,屏幕阅读器的串行读取顺序也使得很难将正确的标签与表单字段关联起来。这个演示将展示TransPAc[5],这是一种辅助技术,可以让盲人填写PDF表单。由于盲人熟悉网页浏览,因此TransPAc利用了这一点,将带有表单的PDF文档忠实地转换为HTML页面。盲人用户使用屏幕阅读器在HTML页面中填写表单字段,这些填写的数据值透明地传输到PDF文档中相应的表单字段中。因此,TransPAc解决了一个长期存在的PDF表单可访问性问题。

Ontology-Driven Transformations for PDF Form Accessibility.

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.
