Abstract
We describe the development and evaluation of across-modal
XML (Extensible Mark-up Language) schema browser. The
aim of developing the system is to investigate cross-modal
collaboration between users. The browser provides an audio
representation of XML schema documents in a way that
preserves the structure of documents and supports multi-level
navigation. The project has two principle objectives: 1) to
overcome the difficulties faced by visually impaired users and
sighted people using small screen devices when browsing XML
schema files, 2) To explore usability issues when users
collaborate using the auditory and visual interfaces of the
system. The paper also examines differences between sighted
and visually impaired users of the developed auditory interface.
The overall results of the usability evaluations
demonstrate that both sighted and visually impaired users were
able to perform tasks using the audio modality efficiently and
accurately, and the same was true of sighted users interactions
with the GUI. The use of the system to support collaboration where
each user employs a different mode (audio or visual) of the
system clearly demonstrated that cross-modal collaboration is
effectively supported, enabling users to collaborate and
successfully complete a complex shared task.
