Cell Phones Become Handheld Tools For Global Development

Mobile phones are on the verge of becoming powerful tools to collect data on many issues, ranging from global health to the environment.
Computer scientists at the University of Washington have used Android, the open-source mobile operating system championed by Google, to turn a cell phone into a versatile data-collection device. Organizations that want a fully customizable way to, say, snap pictures of a deforested area, add the location coordinates and instantly submit that information to a global environmental database now have a flexible and free way to do it.
UW computer scientists were already working on mobile tools for the developing world when Android, the first comprehensive open-source platform for mobile devices, was announced two years ago by the Open Handset Alliance, a group of companies of which Google is a member. For the past year UW computer science and engineering doctoral students Carl Hartung, Yaw Anokwa and Waylon Brunette have worked at Google’s Seattle office using Android to create a data-collection platform for use in developing regions.
Their free suite of tools, named Open Data Kit, is already used by organizations around the world that need inexpensive ways to gather information in areas with little infrastructure. Seattle’s Grameen Foundation Technology Center is using it to evaluate its Ugandan text-messaging information hotline; D-Tree International, a Boston-based nonprofit, is using it in Tanzania to guide health workers treating children under 5 years old; the University of California, Berkeley’s Human Rights Center is using it to record human rights violations in the Central African Republic. This fall the Jane Goodall Foundation in Tanzania and the Brazilian Forest Service signed up to use it to monitor deforestation.
“Many organizations need to be able to make evidence-based decisions, and to do that they need data,” Anokwa said. “We hope our toolkit enables organizations to gather the data quickly so they can analyze it quickly and make the best decisions for the communities they serve.”
