Paper Abstracts

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.

Projecting Health: Community-Led Video Education for Maternal Health

In this talk, I will present a qualitative study of Projecting Health, a public health project we deployed in rural Uttar Pradesh (India) to address persistently high maternal and infant mortality rates. This project is based on our model of Community-led Video Education (CVE), which leverages community resources for the generation, dissemination, and assimilation of visual media. We use the lens of information flows to examine how our instantiation of CVE enables the translation of globally approved health care norms to local household practices. We also demonstrate how CVE allows for integration with current community practices, existing state-supported health care infrastructure, social and patriarchal structures, and power dynamics within our target populations to drive community participation.   A copy of the paper can be found here: ICTD2015_Kumar

What:  Samia Razaq – Maternal and Child Health Projects in Pakistan

When: Tuesday, Feb 17 at 12pm

Where: The Allen Center, CSE 203

Please join us this week for Change.  Smaia Razaq from ITU-Punjab will be presenting information needs surrounding maternal health awareness in Pakistan.


Pakistan has the third highest maternal deaths in South Asia. Globally, more than 350,000 women die each year from preventable complications linked to pregnancy. Maternal Mortality Rate (MMR) is relatively higher in developing countries with a concentration in rural and underserved communities. In Pakistan around 30,000 women die each year due to the pre and postnatal complications.

In this talk Samia Razaq talks about three maternal health mHealth initiatives from ITU-Punjab to address these issues.  Projects include an SMS and IVR system to inform women about family planning, pre-maternal illness and general health, a digitized Android based IMCI protocol being deployed at Ganga Ram hospital, and work on digitizing immunization records.  All three projects help alleviate health information gaps among women, communities and health officials.

Krysta Yousoufian: Fair Trade Phone? Creating More Socially and Environmentally Responsible Electronic Devices

February 9th, 2015 by Trevor Perrier

What:  Krysta YousoufianFair Trade Phone? Creating More Socially and Environmentally Responsible Electronic Devices

When: Tuesday, Feb 10 at 12pm

Where: The Allen Center, CSE 203

Please join us for this week’s Change Seminar.  This week former UW student Krysta Yousoufian will be stopping by to talk about a side project she is passionate about: a fair trade smartphone.  Come learn more about the supply chain behind our ubiquitous devices and what we can do to make it more sustainable.

Please note, there will be a Change Seminar next week Feb 17.


Most of us love our smartphones and other gadgets, and we talk at length about their potential for global development. But there is a dark side to this proliferation of electronic devices: a host of social and environmental costs embedded throughout their lifecycle. How can we do better? At my workplace, a group of passionate employees has been looking at how we can create a more socially, environmentally responsible smartphone. Begun during a company-wide Hackathon and continued on our own time, our project aims to put these issues on the map, create a real alternative, and ultimately change the way the industry does business.

We want you to be part of the conversation. Join a discussion on questions such as: How do we address the most pressing social and environmental costs of our devices? How do we create a device that consumers can trust is “better,” and will they buy it? Are “do well” and “do good” even compatible?

This is an entirely a personal project on our own time. Although our project has benefited from company channels for encouraging innovation, we speak only on behalf of ourselves.
