eKichabi: Information Access through Basic Mobile Phones in Rural Tanzania
2018
This paper presents eKichabi, a tool for retrieving contact information for agriculture-related enterprises in Tanzania. eKichabi is an Unstructured Supplementary Service Data (USSD) application which users can access through basic mobile phones. We describe our focus groups, a design iteration, deployment in four villages, and follow up interviews by phone. This work demonstrates the feasibility of USSD for information access applications that have the potential for deployment on a large scale in the developing world. From user interviews, we identified strong evidence of eKichabi fulfilling an unmet need for business related information, both in identifying business contacts in other villages, as well locating specific service providers. One of our key findings demonstrates that users access information through multiple modes, including text search, in addition to menu navigation organized by both business sector category and geographic area.
