This paper presents the usability testing results for an
authoring tool that generalises scenario creation for a tool called
SignSupport. SignSupport is a mobile communication tool for
Deaf people that currently runs on an Android smartphone. The
authoring tool is computer-based software that helps a domain
expert, with little or no programming skills, design and populate
a limited domain conversation scenario between a Deaf person
and a hearing person, e.g., when a Deaf patient collects
medication at a hospital pharmacy or when a Deaf learner is
taking a computer literacy course. SignSupport provides
instructions to the Deaf person in signed language videos on a
mobile device. The authoring tool enables the creation and
population of such scenarios on a computer for subsequent
'playback' on a mobile device. The output of this authoring tool
is an XML script, alongside a repository of media files that can
be used to render the SignSupport mobile app on any platform.
Our concern now is to iteratively develop the user interface for
the authoring tool, focusing on the domain experts who create
the overall flow and content for a given scenario. The current
authoring tool was evaluated for usability; for both pharmacy
and ICDL course scenarios with purposive sampling. The
findings suggest that the authoring tool can generalise
SignSupport for multiple limited domain scenarios, mobile
platforms and signed languages.
