India, a Personal View
but, power held by fewtremendous energy and optimism
incredible diversity, EM microcosmreminiscent of European Union
impact of weather (ubiquity of agriculture)
huge interest in PCs, by everyoneinformation still flows
(e.g., 250M mobiles)
Huge potential opportunity for computing industry.
But, there are new challenges that
neither India nor the industry have ever faced before.

Technology for Emerging Markets
Understand potential technology users in economically poor communities:
– E.g., urban domestic labourers– E.g., rural entrepreneurs
Adapt, invent, or design applications of computing that contribute to socio-economic development of poor communities worldwide.

Education in India
300M children aged 6-18; 210M enrolled in school; 105M actively attending.
Mostly children of low-income farmers, villagers, migrant wage workers
Teachers poorly trained and frequently absent
Schoolchildren outside of Bhopal

MultiPoint: Solution
Provide a mouse for every student
– One cursor for each mouse, with different colours or shapes
– USB mice• Have tried up to 20
– Content modified • Game-like environment
![Page 18: Computing for Socio-Economic Development](https://reader035.fdocuments.net/reader035/viewer/2022062520/56815915550346895dc63f86/html5/thumbnails/18.jpg)

MultiPoint: ResultsKids understand MultiPoint immediately.
All students more engaged for longer periods of time.
– Even children without mice engage longer.
Self-reporting is positive.– Exception: one student didn’t like
MultiPoint because of competitiveness
For memorization tasks, MultiPoint as effective as one PC per student

MultiPoint: Advantages
Costs reasonable; incentives aligned
– Cost effective: One computer + 5 mice comes to ~$100 per child.
– Content authors can adapt to paradigm
– Government / administrators can claim better use of computers
– Teachers can keep more students entertained
– Students have more fun (cf., multi-player computer games)

Split Screen
Two users, two mice, two keyboards, two instances of the OS, but only one monitor

Split Screen Research

IT training centre in a busy low-income urban community
– Run by HOPE Foundation– Co-certified by state gov’t
Content is basic computer skills education:– Computer basics– Office suite (Word, Excel)
No problems with usability; individual Split-Screen users can accomplish as much as single-screen users.
Minor technical problems.
Collaboration effects strongly correlated with existing degree of friendship between users

Illiteracy
1-2 billion illiterate population in the world.
98% live in developing countries.
India’s rate of literacy (optimistically) estimated at
~60%.
![Page 27: Computing for Socio-Economic Development](https://reader035.fdocuments.net/reader035/viewer/2022062520/56815915550346895dc63f86/html5/thumbnails/27.jpg)
Text-Free UI, Take 1
Design Principles:
– Pen or touch interface
– Liberal use of icons and images
– Voice feedback
– Care in details of graphics; semi-abstracted cartoons
– Aggressive use of mouse-over functionality
– Consistent help iconMonster.com for domestic labourers?
Maps for illiterate users?
![Page 28: Computing for Socio-Economic Development](https://reader035.fdocuments.net/reader035/viewer/2022062520/56815915550346895dc63f86/html5/thumbnails/28.jpg)
Results, Take 1
Task: For a friend who is unemployed, find the best-paying job in her neighborhood.
Results: Subjects could manipulate the application, but only 30% completed the task, even with significant prompting:
Problem: Deeper problem in motivation and lack of cognitive model of how the PC worked.
![Page 29: Computing for Socio-Economic Development](https://reader035.fdocuments.net/reader035/viewer/2022062520/56815915550346895dc63f86/html5/thumbnails/29.jpg)
Can any UI be converted into one that is usable by illiterate users?
ILLITERACY
FEAR OF TECHNOLOGY
LACK OF TRUST IN TECHNOLOGY
LACK OF AWARENESS OF WHAT TECHNOLOGY CAN DELIVER
New Problem!
Can a UI be developed to allow an illiterate, first-time PC user to access information he/she needs without any assistance or prompting?
New question:
Original question:
![Page 30: Computing for Socio-Economic Development](https://reader035.fdocuments.net/reader035/viewer/2022062520/56815915550346895dc63f86/html5/thumbnails/30.jpg)
Full-Context Video
A full-context video explains the broader context of the application and how it works, in addition to instructional material about how to use the application.
Full-Context Video
![Page 31: Computing for Socio-Economic Development](https://reader035.fdocuments.net/reader035/viewer/2022062520/56815915550346895dc63f86/html5/thumbnails/31.jpg)
Results, Take 2100% of subjects completed task with full-context video!
Round-two subjects were incredulous that round-one subjects didn’t understand the application.
Impact of video not permanent for most subjects. Many wanted to see the full-context video each time, even after seeing it before.
Full-context video appears to increase motivation, as well as performance.
Those who saw full-context video were interested in providing feedback on the specifics of the UI.

Agriculture Extension
Dissemination of expert agriculture information and technology to farmers
“Training & Visit” extension popularized by the World Bank in 1970s
– Face-to-face interactions of extension officers and farmers
100,000 extension officers in India– Extension agent-to-farmer ratio is 1:
2,000– 610,000 villages in India with average
1,000-person population
Typical extension officer salary is$100 per month
Extension officer “commuting” between farms

3. Mediated instruction
4. Structured sequencing

20 villages in Karnataka:– Language: Kannada– Crops: Ragi, banana, mulberry, coconut– Population: 50-80 households– Irrigation: 10-20 households with access– Television: 15-20 households
Metrics:– Knowledge: Before-and-after– Attendance: Farmers at each screening– Interest: Intent to take-up a practice– Adoption: Number of households taking up

7 times more adoptions over classical extensionat less cost per village
9 months: 12 villages, 3 nights a week, 1,000 regulars
Sustained local presence
Mediation
Repetition (and novelty)
Integration into existing extension operations
Social homophily between mediator, actor, and farmer
Desire to be “on TV”
Trust built from identities of farmers and villages in videos
Digital Green: Results
Digital Green is at least 10 times more effective per dollar spent than classical extension!
