Robustness of Adobe Liquid Mode for PDF Layout Reinterpretation

Determine whether Adobe's Liquid Mode, which retroactively reinterprets PDF document layout to provide responsive reflow, works effectively across all cases of PDF documents.

Background

The paper discusses inherent accessibility limitations of PDF, particularly the lack of native responsive design and content reflow. Adobe has introduced Liquid Mode in Acrobat as a proprietary, mobile-only feature that attempts a retroactive reinterpretation of PDF layout to address these issues.

The authors note uncertainty about the general effectiveness of Liquid Mode across diverse document types and layouts, highlighting a gap in understanding whether this approach consistently produces usable results in all scenarios.
