Rural developing regions are often defined in terms of their resource constraints, including limited technology exposure, lack of power and low access to data connections (leading to an inability to access information from digital or physical sources), as well as being amongst the most socioeconomically disadvantaged and least literate in their countries' populations. This paper is focused around information access in such regions, aiming to build upon and extend the audio-based services that are already widely used in order to provide access to further types of media. In this article, then, we present an extended exploration of AudioCanvasan interactive telephone-based audio information system which allows cameraphone users to interact directly with their own photos of physical media to receive narration or description. Our novel approach requires no specialist hardware, literacy, or data connectivity, making it far more likely to be a suitable solution for users in such regions.
