Demo: Visualizing USSD and IVR Usage Data with Icicle Charts

Software designers in many parts of the world rely on Interactive Voice Response (IVR) and Unstructured Supplementary Service Data (USSD) to create applications that work universally on basic mobile phones. In this work, we demonstrate our use of hierarchical visualizations like icicle charts to explore the usage data generated by IVR and USSD applications, helping designers understand user behavior and evaluate the efficacy of the applications’ different components. By adding interactive elements, a viewer could zoom down to to see details about users’ behavior from a certain screen, or filter users by different demographics.
