Mobile Tech for Social Change Barcamp

Last Saturday I attended the Mobile Tech for Social Change barcamp. From their website —

Mobile Tech 4 Social Change Barcamps are local events for people passionate about using mobile technology for social impact and to make the world a better place. Each event includes interactive discussions, hands-on-demos, and collaborations about ways to use, deploy, develop and promote mobile technology in health, advocacy, economic development, environment, human rights, citizen media, to name a few areas. Participants for Mobile Tech 4 Social Change barcamps include nonprofits, mobile app developers, researchers, donors, intermediary organizations, and mobile operators.

The event began with a talk (via Skype!) from Ethan Zuckerman, who I had seen speak previously in my Applications class last semester. He’s been involved in various service projects in Africa and is a co-founder of Global Voices Online, a community brought together by ‘bridgebloggers’ that translate posts between languages and cultures. His most salient and useful point was that mobile technology was most powerful when it was paired with another medium, such as FM radio.


I went to three breakout sessions. The first was given by a few people from the Innovations Team at UNICEF and a couple of students from Columbia working on the aforementioned Malawi project. I had seen some of what they presented before, but got to play with the RapidAndroid version of the RapidSMS software (which runs on a G1 mobile phone), and I saw some sample database inputs and SMS form instructions. In addition, I learned that while initial SMS error rates have been high in the pilot studies, the system will respond asking the user to resend the message, and this feedback loop is effective at teaching users to send correctly formatted SMS messages. My group in the Design for UNICEF class will continue with our Mechanical Turk project — there will still be unparseable messages or messages that don’t get resent — but it will be good to keep this in mind as we develop.

In between sessions I saw a demo from an MIT PhD student named Nadav Ahrony at the Viral Communications group at the Media Lab. He was working on a not-yet-released general platform for development of wifi/bluetooth peer-to-peer mobile applications. He had built a demo application that would let people associate their phones with a particular group of phones, and then automatically sync content on these phones over an ad-hoc network. The most interesting use case he suggested: if a protester takes a photo with the device, and there is risk that the device might be confiscated, it will automatically be downloaded by the others in the group immediately after being taken, so even if the original device is lost the data is not.

The second breakout session was lead by Josh Nesbit, a current undergrad at Stanford graduating this year. He presented an SMS-based project he did in Malawi for hospitals and the surrounding villages that used FrontlineSMS, an alternative SMS platform (that isn’t necessarily comparable in aim to RapidSMS). More information on that project is available here.

The last breakout session was for mobile developers, and we had an interesting conversation about developing for Android. Overall I enjoyed the day and found it useful, and I’m looking forward to going to the next m4change barcamp.
