Abstract

Emerging technologies provide information to people living in rural poverty. However, using information to affect health or farming practices requires overcoming unique challenges including illiteracy and lack of electricity. We examine the effects of a low-cost audio computer ("Talking Book")-a handheld device enabling users to create, listen to, and copy recordings-for improving learning and knowledge sharing in such environments. In northern Ghana, we studied the impact of giving rural villagers on-demand access to guidance created by local experts. Our evaluation shows Talking Books significantly impact learning, behavior change, and crop yields in a village with low literacy rates and no electricity.
