Big themes in ICTD
Mobile phones are the thingThere are more mobile phones (6B in 2014)
in the world than toothbrushes1B Android phones sold in 201485% mobile penetration in Africa+10% mobile penetration +.6% GDP
Leverage limited numbers of highly trained peopleUse technology to empower less-trained
people

General Challenges
Diverse languages and scripts22 different languages in India alone
○ Wikipedia is not useful in these regions
Low literacy Really poor people are just like us
Don’t want to study in their spare timeBut they have less spare time!
Armed conflict, unstable governmentsThe war in the DRC has killed 5.4 million since 1998

Pre-Natal education
Work done by Ramachandran et al in a collaboration between Berkeley and MSRI
Better suited to one-on-one interaction Difficult to persuade people to change
traditional practices Trust is very important!

Maternal mortality In 2012, India recorded more maternal deaths than
any other country in the world (around 56,000 per year),accounting for more than 20% that occur globallyFor comparison, in 2011 in US, 32,367 people died in car
accidents
A preliminary study has shown that moving deliveries from home to the hospital can reduce maternal mortality by half.
But in India, over 60% of all deliveries are still conducted at home, without a skilled birth attendant.

Empowering “Ashas”
Ashas are women in villages in India who are charged with convincing pregnant women to use health services and educating them about warning signsASHA = Accredited Social Health ActivistPersuading family as wellAshas’ status in the village is questionable“Very early, we were struck by the regularity with
which village women chose to ignore advice from health workers, and decline use of free health services”
21
Mobile phone as video creation AND presentation device Ashas are given some videos to start,
but can also make their own videos Videos of village elders
endorsing practice especially
usefulCache of technology
22
Findings (1) videos served as anchors for health discussions
that both scaffolded the ASHA and engaged her clients, a necessary precursor for persuasion
(2) creation of videos was motivating and fun for ASHAs
(3) high-status influencers in the community participated in video creation to a surprising extent
(4) Improved ASHA motivation (5) modest learning gains by ASHAs

Expanding Rural Cellular Networks with Virtual Coverage Work out of Berkeley’s TIER group
Start-up recently acquired by Facebook Mobile phones are a huge driver of
economic developmentRemittancesGetting goods to market
The cellular network is the biggest network in the world ~6B usersBut ~1B are uncovered, mostly in rural areas of
developing world.
Why aren’t they covered? Too expensive to build and operate towers.
Why?Power!“Contacts in rural areas have reported prices
between five hundred thousand to one million USD for the installation of a cell tower in an area without existing power or network”
The International Telecommunications Union has indicated that 50% of the OPEX cost for a rural network is power
Goal: Reduce cost of expanding the network
Make it cheaper by saving power Currently, turn it off at night
In the Punjab province of Pakistan, no power to the tower for over eighteen hours a day
So no calls, including emergency calls
Can we be smarter about when it’s turned off?“Virtual coverage”The tower turns off when no one is using it and
turns on when someone wants to make a call.
“Virtual Coverage”
This design allows us to save a large amount of power in the largest networks on Earth while still providing consistent coverage at all times.
• Sounds simple, right?
Not really! Requires changes to the way the tower
works. You can make a tower that will
automatically wake up for an incoming call, BUTa special device is still needed to wake
it up for an outgoing call.
They built the tower, and the device,
and a phone with the device built in!
Results “idle” mode saves between 65% to 84% of the
power on a tower. user’s experience is not dramatically affected Call setup increases by 2 seconds with Wake-up
Phone At most 25 seconds with normal phones and Wake-
up Radio (the cheaper solution) An installation using virtual coverage in a low-density area could operate with less than one-sixth of the solar panels, batteries, and price of a traditional setup.
Results
Reduce the network power draw by 34% at night (21% during the day) for a South Asian operator.
In sub-Saharan Africa, where towers are more heavily utilized, save 21% of the power at night (and just 7% during the day)
Allow cellular companies to expand into new areas more cheaply

Benefits of Facilitated Video It enables a less skilled person to lead class Provides teacher training while teaching
BUT it relies heavily on the facilitatorInteraction is vitalThe quality of interaction matters
39
How can we ensure high quality and quantity
of interaction?Technology to increase capabilities of facilitators
Goal:
Use technology in facilitated video to provide structure to the interactionsupport to the facilitator
40
Contributions of this work:
41
Identifying the kind of support that is helpful to the facilitatorTargeted facilitation advice
Building two different technological solutions to provide support
Field testing and evaluating these solutionsWith a real deployment
Custom hardware remote control Audio Codes/Android Device
Talk Outline
Identifying what kinds of support are useful The technological solutions we built Field testing and evaluation of technological
solutions
42
What kinds of support are useful? During a 12-week investigationTried several interventionsUnderstand facilitator’s needs using low-tech prototypes
The most successful was providing information to the facilitator using subtitlesAdvice on when to stop
the video and
what to say
43
Lessons Learned
44
Helped a novice facilitator create more interaction Could it be useful for more advanced facilitators?
Enriched the kind of interaction
This is the approach we pursue:Providing information to the facilitator
Talk Outline
Identifying what kinds of support are useful The technological solutions we built Field testing and evaluation of technological
solutions
45
Approach: Provide prompts to the facilitator When to stop the videoWhat to sayOn a handheld device
Why use a handheld device? For monitoring the facilitator
Providing information to supervisors about the facilitator’s behavior
It provides a private channel to the facilitator
Allows us to provide richer materialsLonger prompts, pictures
Much easier to update materials
46
There is a challenge: How does the device know what video is playing and where it is?
47
We developed two different approaches
to this problem
Why two separate approaches? The two approaches have
complementary strengths and weaknesses
Rather than guessing which was betterEvaluate in the field with real users
48
First Approach: “Smart” Remote Control
Custom hardware device Normal remote control
+ screen for presenting information When the user puts the DVD into the
player, they enter that DVD’s ID
number Then the device tracks button presses to
know which video is playing and at what time offset
49
Second Approach:Audio Codes + Android Application Create (audible) “audio codes”
with distinctive frequency distribution
Embed them into the video at regular intervals
An Android-based application Activates the microphoneListens to audioUses simple digital signal
processing to the detect codes and display the correct information

How do we define Success? This determines how we design our study:
If success is: adoption of the systemOur study will be exploratoryWill focus on understanding “best practices”Will be an in-depth study of small user baseThis is more useful to Digital Green
If success is: rigorous evaluation of technology and deployment strategyOur study will involve randomized assignmentHave rigid up-front designBe a less detailed study of large user baseYield more generalizable results
53
Our goal is to build a system that is useful to Digital Green, so we define success as:
Adoption of the systemOur study will be exploratoryWill focus on understanding “best practices”Study will be an in-depth study of small user base
Field trials
4 week deployment 3 audio code users 1 remote control user
54
Goal was to understand use cases
We collected several kinds of data to do this:Audio recorded showsLog data from the devicesFacilitator surveys after each showSemi-structured interviews with facilitators
55
User responseIn interviews, all users said: They liked using the deviceIt helps them remember the points they should highlightWithout it sometimes they would forget points Facilitating was easier; without the device they needed to watch the video more closely
56
All the users enjoyed the deviceBut different users used it very differently
This is a solution people can and will use But they will use it in different ways and for
different reasons
57
Benefits gained by:
New facilitatorsEncourage questionsLearn timingGain confidence
58
Experienced facilitatorsExpand repertoireAllow more multi-tasking during showReminder of details
Lessons Learned – Audio codes
Acoustics affect recognition of audio codesMistakes did not decrease trust in the deviceWe would like to design a more sophisticated, robust
coding system
People didn’t mind noise from codesLikely because videos are of generally low production
quality
59
Lessons Learned - Remote
Not an extra deviceReplaces existing remote
Remote can get out of
sync with DVD player
60
Remote control commands
don’t always reach DVD
playerAs with audio codes,
mistakes did not decrease
trust in the device
Conclusions Support for the facilitator has a number of benefits
Improved interactionIncreased confidenceFacilitation trainingMaking facilitation easier
Context mattersAffects which benefits are realizedThe setting and the users matter
