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
