/Engaging Pregnant Women in Kenya with a Hybrid Computer-Human SMS
Communication System/
A growing body of HCI4D research studies the use of SMS communication to
deliver health and information services to underserved populations. This
paper contributes a novel dimension to this field of study by examining
if a hybrid computer-human SMS system can engage pregnant women in Kenya
in health-related communication. Our approach leverages the different
strengths of both the computer and the human. The computer automates the
bulk-sending of personalized messages to patients, allowing the human to
read patients’ replies and respond to those in need of attention.
Findings from a 12-month deployment with 100 women show that our
approach is capable of engaging the majority of participants in
health-related conversations. We show that receiving messages from the
system triggers participant communication and the amount of
communication increases as participants approach their expected due
date. In addition, analysis of participants’ messages shows that they
often contain sensitive health information conveyed through a complex
mixture of languages and ‘txting’ abbreviations, all of which highlight
the benefits of including a human in the workflow. Our findings are
relevant for HCI researchers and practitioners interested in
understanding or engaging underserved populations.
/Sangeet Swara: A Community-Moderated Voice Forum in Rural India/
Interactive voice forums have emerged as a promising platform for people
in developing regions to record and share audio messages using low-end
mobile phones. However, one of the barriers to the scalability of voice
forums is the process of screening and categorizing content, often done
by a dedicated team of moderators. We present Sangeet Swara, a voice
forum for songs and cultural content that relies on the community of
callers to curate high-quality posts that are prioritized for playback
to others. An 11-week deployment of Sangeet Swara found broad and
impassioned usage, especially among visually impaired users. We also
conducted a follow-up experiment, called Talent Hunt, that sought to
reduce reliance on toll-free telephone lines. Together, our deployments
span about 53,000 calls from 13,000 callers, who submitted 6,000 posts
and 150,000 judgments of other content. Using a mixed-methods analysis
of call logs, audio content, comparison with outside judges, and 204
automated phone surveys, we evaluate the user experience, the strengths
and weaknesses of community moderation, financial sustainability, and
the implications for future systems.
*Bio:* Aditya Vashistha <http://www.adityavashistha.com/> is a second
year PhD student in CSE. Prior to coming to UW he was at MSRI working
with the Technologies for Emerging Markets

interests are in the domain of Information and Communication
Technologies for Development, Human-Computer Interaction for
Development, Social Computing and Ubiquitous Computing.
Trevor Perrier is a third year PhD student in CSE. He works closely
with UW Global health to implement SMS projects for behaviour change.
He is interested in building systems that engage individuals through
ubiquitous communication technology.
