Much of the world's knowledge is captured in writing, and shared through writing, and as such is inaccessible to the one eighth of the world's population who are illiterate. We are developing a software system for the use of this population based on speech and images without written text. We have evaluated basic interaction devices and simple interface metaphors to arrive at the design of an overall interface that is attractive to and usable by illiterate people. We report our usability experiments, and describe our system.
