Will the New Mobile Era Change the World for the Better? MIT Says "Yes"

Nokia5800XpressMusic_Lifestyle_4_lowres_rsz The release this week of Google's new Android-based Nexus One smartphone should prove to be the iconic symbol of the new mobile computing era. As people increasingly rely on powerful mobile phones instead of PCs to access the Web, their surfing habits are poised for change that may prove as dramatic as the past shift from PC desktop to the Internet Era. What’s more, smartphone apps could replace online advertising as the Web’s primary economic engine, putting Google’s leadership role into question. 

Meanwhile, at MIT teams of the Media Lab's Next Billion Network -our next generation of tech movers and shakers- are exploring new ways to harness the increasingly ubiquitous cellphone to help people in developing nations to raise their incomes, learn to read, get where they're going, and diagnose their health.

The teams are attempting to answer the question "can you make a cellphone change the world?" says Jhonatan Rotberg, director of the  Next Billion Network, formed to examine potential applications for the next one billion people expected to become cellphone users over the next three years. With cellphones now in the hands of four billion people worldwide, Rotberg says, "we're at the threshold of something important in history."

Other cellphone applications for people in low-income countries are being developed by fellows at MIT's Legatum Center, whose director Iqbal Quadir was the founder of Bangladesh's GrameenPhone, a company that by introducing a low-cost cellphone service to Bangladesh starting in 1997 provided an early example of the power of mobile technologies to advance prosperity in the developing world.

"Since mobile phones are dispersed throughout the developing world, they now constitute a platform atop which other services - mobile banking, mobile health, etc. - are now possible," said Michael F. Maltese, the center's managing director.

Improving the delivery of health care in rural areas has been one major focus of these research efforts. Patients in a remote village, for example, now may have to spend a whole day or more traveling to the nearest clinic in order to be tested, diagnosed and receive treatment or a prescription drug for their health problems. But a new open-source software system developed by students who formed a nonprofit company called Moca could provide a faster way.

Using a menu of questions downloaded to a cellphone - and, if necessary, a picture taken with the phone's built in camera - a patient can transmit enough information to a doctor or nurse in a remote location to get a preliminary diagnosis, and to find out whether the condition warrants a trip to the clinic or not. "In developing countries, 80 percent of all physicians are in urban areas," while most of the people live in the countryside, says Moca team member Richard Lu, an MIT graduate student in biomedical informatics.

While Moca and Click Diagnostics aim to improve people's health, some new cellphone ventures also aim to build users' wealth. One such plan is a project called Zaca, which initially aims to empower farmers in the poor, rural Mexican state of Zacatecas.

Farmers there have been doing so poorly that many have already emigrated to the United States (it is estimated that up to 1 million Zacatecans now live in the U.S., compared to about 1.3 million still in the state). The Zaca team hopes to alleviate the situation by giving the farmers more information, allowing them to make deals through their cellphones to sell their crops directly instead of having to deal through middlemen, and giving them details of crop prices and growing practices that can help them make better decisions about what to plant each year.

Members of the Zaca team plan to work on the project in Zacatecas this summer, and then hope to expand the service to other parts of Mexico, as well as to other developing countries in Africa and Asia. They also hope to expand beyond farm information to provide similar services for rural fishing, forestry, crafts and other businesses. By using text messages on cellphones, says team member Ehsan Hoque, a graduate student at the Media Lab, the Zaca service provides "a cheap solution that could be used anywhere."

Farmers may get a better price for their crops using the Zaca system, but most of them are still unable to make use of modern banking systems, since there are usually no banks accessible in these rural communities. Only about 30 percent of people in Mexico have bank accounts, which means they earn no interest on what little money they have, and are unable to write a check to pay their bills. Dinube, another NextLab project, aims to solve that by providing banking services directly through people's cellphones.

The Dinube system, which will be tested in Mexico this summer, doesn't require its users to have bank accounts or debit cards, but enables them to make payments directly through their phones for a small fee.

One of the Legatum Center fellows, Ravi Inukonda of Sloan, is developing a for-profit model for bringing new mobile services to the estimated 200 million rural cell phone subscribers in India. These added applications include informational services such as updates on water and power shutdowns, current local market rates for produce, and weather forecasts, and allow for transactions between buyers and sellers.
Mobility and literacy

A variety of other applications for cellphones in remote areas are also being developed, including some aimed at improving coordination in areas where transportation both for people and goods is often unpredictable. One such system, called Transport Link, also developed in NextLab, is a way for people who rely on infrequent bus service to get timely updates on when the next bus will come through their area, or to arrange informal transportation with others in the area who have private vehicles.

For commercial transport, a company called Hammock aims to provide a way for shippers to connect with truckers, allowing for a better coordination of resources so that trucks are less likely to travel half-full, and farmers, for example, can get their goods to market without fear of spoilage.

Legatum Fellow Adnan Shahid of the Sloan School hopes to bring his previous experience as director of IT strategy for MobiLink in Pakistan, to the business of recycling cell phones in that country. Worldwide, only 10 percent of cell phones are recycled each year, resulting in wasted natural resources and higher greenhouse gas emissions. The environmental savings could be significant for Pakistan, whose cities consistently rank among the most polluted in the world.

But there's more to life than good health, economic empowerment and mobility. Another project aims squarely at ensuring a better future by improving literacy for impoverished people, especially young people, in developing countries where education is often a luxury that remains out of reach for millions of people.

The project, called Celedu, is starting its work in some rural villages in India, but hopes to expand far beyond that. Its initial offerings include cellphone-based games and quizzes that can teach basic literacy skills. For example, a child in India can play a game of Snakes and Ladders on the phone by answering multiple-choice questions about which words begin with a particular letter in the Hindi alphabet. Each correct answer allows the child's marker to advance through the game board, providing a fun and competitive approach to learning the written language.

"The biggest disease in India is illiteracy," which affects 400 million people there, says team member Rafael de Cardenas of Sloan. A PC-based version of the program, called Tele Akshar, "has already taught 54,000 women in 300 villages," he says, and the cellphone version should be able to reach far more people.

For all the projects, "our overarching goal is scalability," says Rotberg. His hope is that the student teams will be able to develop technological solutions and demonstrate the viability of their business plans, and then "take them to other parts of the world, where entrepreneurs can take it and run with it."

"which means they earn no interest on what little money they have" hmm I dont think that would make a difference I think in the 10 years Ive been banking ive been lucky to have received maby $0.60 total in interest and the banks in the mean time are constantly thinking of more and more creative ways to create fees and fines to take away your money. So if they had banks it would probably make them poorer. i know thats whats happened to me. Thats why i dont use the banks to put my money unless i absolutely have to. I found if I keep my money out of the banks I actually have more of it.

This article reminds me that wonderful things can and do happen when people care more about people rather than about enriching themselves. This article makes my day.

This is a compelling read and although I don't know much about mobile technology, won't there need to be some sort of infrastructure to make these phones work? Surely the costs of this infrastructure would be significant and only a telco looking for ROI would be interested to make the investment?

It depends upon the person how he uses the new technology it can be used for both good and bad.
