Abstract:
This paper describes a novel tool for eliciting user requirements
early in the design process of mobile applications. The “Mobile
Oracle”, as we have called it, is intended to help developers and
designers obtain a better understanding of what the user wants at
different points in space and time. It is an extension of a lo-fi
version of the well-established Wizard of Oz technique, but it also
adds an “on demand” component to force users to explicitly
request the information they need. The technique has been tested
in an investigation involving 15 users (sighted, visually impaired,
and elderly). Results show it to generate valuable information
concerning the ways people ask about directions and distances, as
well as the services they would like to have in future mobile
applications.
