*What*: Nicki Dell: Field Evaluation of a Camera-Based Mobile Health
System in Low-Resource Settings
*When:* Tuesday, Oct 21 at 12pm
*Where:* The Allen Center, CSE 203
Please join us this week at Change as Nicki Dell presents findings from
a field evaluation in Zimbabwe where her Android based diagnostic tool
into was interoperated into the health services work flow.
*Abstract:*
The worldwide adoption of mobile devices presents an opportunity to
build mobile systems to support health workers in low-resource settings.
This paper presents an in-depth field evaluation of a mobile system that
uses a smartphone’s built-in camera and computer vision to capture and
analyze diagnostic tests for infectious diseases. We describe how health
workers integrate the system into their daily clinical workflow and
detail important differences in system usage between small clinics and
large hospitals that could inform the design of future mobile health
systems. We also describe a variety of strategies that health workers
developed to overcome poor network connectivity and transmit data to a
central database. Finally, we show strong agreement between our system’s
computed diagnoses and trained health workers’ visual diagnoses, which
suggests that our system could aid disease diagnosis in a variety of
scenarios. Our findings will help to guide ministries of health and
other stakeholders working to deploy mobile health systems in similar
environments.
*About the speakers:*
Nicki Dell is a final year PhD Candidate in Computer Science and
Engineering at the University of Washington in Seattle. Her research
interests lie in human-computer interaction and mobile computing with a
focus on designing and evaluating systems that improve the lives of
underserved populations in low-income regions. Her PhD thesis focuses on
the technical, user interaction and deployment challenges of integrating
mobile, camera-based systems into resource-constrained environments.
Nicki obtained a BS in Computer Science from the University of East
Anglia (UK) in 2004 and an MS in Computer Science and Engineering from
the University of Washington in 2011. Nicki has won several awards and
fellowships including a Graduate Facebook Fellowship and a Google Anita
Borg Scholarship. She has completed internships at Microsoft Research in
Redmond, USA and in Bangalore, India and has helped to organize the
Change group at the University of Washington since 2011.
