Open Data Kit (ODK)

Project started in 2008

Mobile data collection tools for Android devicesThere was too much focus on clumsy J2ME devicesNot enough focus on the trajectory of technology

Modular, open architecture

Too many stove-piped solutionsLarge commercial enterprise systems

Open source (Apache2)To use for any purpose

ODK Usage

ODK has been a successful open source projectWebsite usage stats (still doubling every year)

Over 150K unique visitors from 202 countriesAverage of 10K unique visitors/monthCode site gets over 3K unique visitors/month

Online survey (73 respondents) last year (small portion of users)

55 deployments involving >5500 devices in 30+ countriesInstalls and code downloads3.5K code downloads25K distinct clients have installed ODK Collect using PlayNOTE: many orgs setup their devices directly w/o Play



10/33

Community

Mailing list of over 1K, developers list of over 500

Many consulting companies (25+)support the ODK tool suite

How we work

Identify technology needs from on-the-groundexperience

Work with local NGO to strengthen their systems

Focus research questions on improvements rather thanoutcomes

Provide community with new building blocks



31/33

Capstone Design Courses

Incubators for new ideas

3 Gates Grand Challenge Grants to dateMidwives Ultrasound (with UW Radiology) - UgandaMilk Banking (with PATH) South AfricaODK Scan (with VillageReach) - Mozambique

All projects have external customers local NGOs

Students from CSE and Human-Centered Design & Engr.work in teams with course staff as managers



32/33

Future Work

Further refinement of ODK Tools for non-programmers

Integration of interactive voice response (IVR) and SMS

Complete sensor data flow including provenance

Improved security and privacy

Connection with electronic banking systems
